Analysis of the cause of alkali

When using cement mortar wet stickers, the alkaline substances in the cement react 3 hydrolysis reactions. A large number of CA2+ and OH- use water as a medium, to reach the surface of the stone through the stitching gap or pores of the stone. Powder -like substances are called alkali. CASIO3 + H2O → Hydrolysis → CA2 + + H2SIO3 + OH’s alkaline substances returned to the air carbon dioxide, sulfur dioxide and other substances in the air, and various substances such as calcium carbonate, calcium sulfate, and calcium sulfate are called Baihua. Essence Baihua has a serious erosion effect, which will destroy the surface of the stone.

Analysis of the cause of pollution

白色石材防护、加工、 施工方案

The micro -cracks and gaps of stones are pores, which will automatically adsorb various liquids, small dust and pollutants, various water -soluble or oily organic pigments. With the help of liquid penetration into the stone pores of the stone, pollution stone forms organic stains, stone materials, stone materials, stone materials, stone materials, stone materials, stones The higher the pore rate and water absorption rate, the easier it is to cause pollution and lesions. At the same time, the number label and non -dry glue on the surface of the stone on the surface of the stone will also pollute the stone.

(3) Brown: algae, wood chips, coffee, tea juice, tobacco, lubricating oil, gasoline, chocolate, urine, etc.

(4) Gray -white: aluminum dandruff, Baihua, etc.

(5) Green: fuel, green ink, copper rust, algae, etc.

(6) Orange: iron rust, fruit drinks, food, etc.

(7) Red: blood, red ink, iron rust, food, etc.

(8) White: aluminum dandruff, Baihua, etc.

(9) Yellow: cloud stone gum, lubricant, iron rust, urine, metamorphic wax, wood chips, three grasses, paper packaging, etc.

Analysis of the cause of yellow change

The main causes of stone yellow change are:

白色石材防护、加工、 施工方案

(1) Stone protection is not in place, resulting in the iron ions in the stone and water reactions, forming iron oxide, which leads to yellow changes in stone, and white series stone such as elegant white, jazz white, and big flowers white is particularly prominent.

(2) During the processing of stone, the equipment and blade rust spots are polluted to the back of the stone;

(3) The failure of the finished product protection measures will cause iron to harm stone, or the iron in the water rust, affect the stone, and cause yellow change.

白色石材防护、加工、 施工方案

(4) Stone maintenance is irregular: After the acidic pharmaceutical effect is react with the steel wire cotton reaction, the material penetrates into the pores of the stone, resulting in yellow change.

(5) During the polishing process, the use of stone wax containing pigment or acid -alkalinic substances, causing stone yellow changes.

白色石材防护、加工、 施工方案

Analysis of color difference

The main reasons for stone production are:

1. Stone waste comes from different pits or different levels and directions;

2. There is no typesetting after the stone cutting and processing;

3. Follow the code and batch number of the supplier’s supply;

4. During the wet paving process, the bonding material used is exposed to the surface of the stone, which causes poor stone color after reaction to the stone;

5. After a period of use of natural stone, the color gradually began to fade, and the original bright and beautiful stone began to become dark or not.

5.1. The chemical composition of the stone has changed. For example, some color reactions in the stone have an oxidation reaction and the air in the stone causes the color change;

5.2 Some minerals in stone loses crystalline water, which reduces the color saturation of the stone;

5.3 The acid gas or acid rain in the atmosphere changes the color and brightness of the stone;

5.4 Paste space: Stones with strong shots in ultraviolet rays are more likely to change.

Stone lesion control

Step 1: Pre -control

白色石材防护、加工、 施工方案

1. Before the stone order, there must be a special person to see the large plate to the stone factory to understand the color and volume;

2. It is best to find the raw ore and master the reserves of the mine source;

3. The stone waste should come from the same pit or the same level;

4. Selection of stone processing manufacturers:

(1) The same parts of the same part, different parts, but related to the relationship between the relationship, and the splicing relationship shall be processed by the same manufacturer;

白色石材防护、加工、 施工方案

(2) The same material should be processed by the same manufacturer;

(3) The same part of the same part with the same type of material with different types and plates should be processed by the same factory.

5. Perform effective communication with stone manufacturers: material output rate, processing loss rate, backpill and backplane method, protective measures, grinding backward angle process, polishing gloss, open hole, packaging method, etc. must be determined by the same way.

白色石材防护、加工、 施工方案

(1) Clarify the product delivery period and processing sequence of product delivery to manufacturers, and have clear production plans (2) Clarify product processing quality standards: appearance, size deviation, gloss, etc.;

(3) Clarify the requirements of the color, style, and patterns of raw materials: Small samples should be designed, Party A, stone manufacturer, and project department confirmed (at least 300*300mm in small samples, preferably 1m*1m);

(4) Clarify the main position of the project, especially the key position, first ensure the quality of the stone material;

(5) Clarify the specific processing site and the quantity of processing.

(6) Clarify the method of picking up the goods, and go to the detailed location of the unloading;

(7) Clarify the responsibilities and compensation standards of the two parties.

Step 2: Stone processing control

白色石材防护、加工、 施工方案

1. Stone processing process (stone manufacturer)

1. Stone cutting must be cut with infrared cutting machine to prevent problems such as blasting edges;

2. The ground -shaped stone spelling should be reasonably designed and divided into seams, customized in the manufacturer, and cutting with a professional water knife.

3. Clean the water on the surface of the stone on the surface of the stone, such as diamond sand, dust, etc.

4. Put the board in a ventilated and dry place for more than 48 hours to ensure that the stone is dry and stacked. When the construction period is tight, you can set up a dry house or a blower;

5. The stone exhaust layout should be produced according to the size of the stone hair embryo, and the loss should be reduced as much as possible. If the loss is too large, the design plan should be adjusted in time (the best ground stone is not greater than 800*800mm). The stone layout map should be designed according to the on -site size. If stone is paved, the number of molds should be set as much as possible to reduce losses.

6. Stone control of stones: snowflake white, fish belly white and other stones are difficult to replenish. It is best to use rough stone to powder and add glue to repair; if the pattern is not connected, it is not recommended to use modification methods If the effect is not achieved, it will destroy the original line. Stone to control processing process: (1) Material selection: select the large board with obvious patterns;

(2) Polish and polishing on the front and back of the large plate: According to the sequence number of the barred board, the front large plate is processed as the light surface, and the bottom surface of the dual large plate is processed into the light surface to ensure that the number of positive and negative numbers is half;

(3) Patient processing: Select half of the processing pattern of the single -number plate, select the other half of the dual -number plate processing picture case, and select the large board processing in order in order;

(4) Machining effect verification: During processing, according to the processing single number diagram, place the cut stones on the ground, make it while swinging, and then pair it. Number and arrow direction.

7, reverse waterproof gel treatment

7.1 Preparation: The waterproof liquid and powder are weighed according to the proportion of the instructions, and the electric mixer is fully mixed and evenly (add the liquid first when stirring, add the powder while mixing) for 5-10 minutes. Construction after elimination;

1) Allow the limit deviation of the diagonal line is 0.5mm;

2) The requirements for geometric size are negative differences (1mm);

白色石材防护、加工、 施工方案

3) The surface flatness allows the error to be positive and negative (specification: 1000mm x 1000mm);

4) The thickness and negative tolerance of the thickness is not greater than 1mm;

5) The surface smoothness is not less than 85 degrees;

Five -sided protection: deal with the four sides of the stone

Noodles and positive protective protection

Material: oily protective agent

Apply brush method: First brush the side, turn to the front when the side is brushed, and ensure that the side yang corners are painted in place, and finally brush the front, and then dry. Standard: JC/T973-2017 Natural stone protective agent for building decoration

How to distinguish the protective agent

(1) I heard: It can distinguish the solvent -type protective agent (odor) and a complete water -based protective agent (no gas flavor). From different odors, it can also distinguish the oil -soluble solvent -based maintenance agent and water -soluble solvents.

(2) Burning: Can distinguish the solvent -type protective agent (can be or flammable) and a complete water -based protective agent (non -combustible) (3) See: The liquid of the maintenance agent is a milk -white protective agent, and the colorless ones are other ones for others. Conservation agent. In addition, put the maintenance agent into the glass and then inject water, the oil -based maintenance agent with the water layer; the water -based maintenance agent that is completely fused with the water.

(4) Touch: The two protective agents of silicon and fluoride have a slippery feeling. Both propylene acid protective agent has a strong viscosity. Silicon C. A sense of viscosity.

(5) Called: 1L of maintenance agent is called weight. Under normal circumstances, it is less than 1 kg of oily; equal to or more than 1 kg is water properties.

Packaging requirements:

Stone plate packaging should be determined according to factors such as quantity and transportation conditions. The form of packaging is divided into wooden box packaging and grass rope packaging. It is not recommended to pack straw rope for white plates, because the straw rope is prone to pollute stone, resulting in yellowing. Wooden box packaging: Compare the light surface of the board, and place it in the box of the inner lining tide -proof paper in order. The wooden box must not be used for external materials. Add an iron waist hoop and an iron bag on the horizontal gear. After panel packaging, the number or name, specifications and quantities of the plate should be attached; the materials of the supporting engineering should be numbered on each plate; “The indication logo, its symbols and usage methods shall meet the provisions of GBL91-73” Packaging Storage and Transport Sign “.

白色石材防护、加工、 施工方案

Transportation requirements: handling and loading must comply with the following regulations:

(1) Put lightly when handling, and it is strictly forbidden to fall. When the upright code is released, the back of the back must be on the edge of the edge; The edge edge of its force must be pad;

(3) When loading and unloading with heavy equipment, it is advisable to hang a box each time;

(4) The loading code should be carried out in accordance with the storage requirements. The requirements of the transportation are stable and the collision is strictly prohibited.

Storage requirements:

The stone plate should be stored indoors, and the outdoor storage must be covered. When the board is placed, the light surface should be relative. The tiltness should not be greater than 15 °. The height of the stack is 1.6m. The bottom surface and between the layers must be pads without polluting the elastic material. When the code cannot be placed upright, the light surface should be opposite, and the ground should be flat and solid. The height of the product after the packaging is 2M.

Step 3: Stone Paper Control

1. Grassroots preparation: Before construction, we must pay attention to grassroots treatment. It must ensure that the grassroots are strong, flat, and no drums. Cracks and contraction cracks; ensure that the grassroots have completely solidified before the stone installation;

2. Grassroots treatment: Wet the grassroots water with water, and clean the construction after the base layer is not bright water.

3. Material preparation:

3.1 Stone: Stone should avoid the dark cracks or damage of the board caused by rolling or collision; the time should not be too long when stacked outdoors, and the sun should be avoided. 4 hours to move into the interior to solve the melody; the construction of the rainy season should be covered with waterproof cloth to prevent the rain and wet.

3.2 Bonding material: Special adhesive for white cement or stone

白色石材防护、加工、 施工方案

4. Tool preparation: handheld mixer, 10*10mm jagged knife, scraper, shovel, rubber hammer, horizontal ruler, mixing barrel, brush, sprinkler, sponge, etc.

5. Environmental requirements: The environmental temperature is best at 10 ~ 40 ° C, if it is lower than 5 ° C, the construction environment and the adhesive should be heated. When the construction is lower than 0 ° C or higher than 40 ° C. The curing is incomplete and the intensity is reduced; the temperature is too high, the reaction is too fast, and the construction time is not enough.

6. Material weighing: The double -component adhesive is notified according to the proportion required by the instruction manual.

7. Avoid using sea sand with more calcium, magnesium, and sodium plasma, and avoid using groundwater with a lot of minerals as mixing water to reduce the source of metal ions.

白色石材防护、加工、 施工方案

The method of identifying sea sand and river sand:

(1) Different from the appearance of Haisha and river sand: From the appearance color, the color of the sea and sand is dull, dark brown, and the color is lighter. The color of the river sand is relatively yellow. From the perspective of granular pieces, Haisha generally has shells such as shells, and river sand will have different sizes.

Stone lesion control

cobblestone.

(2) Use the instrument to measure the chlorine ion content: the electrode method is selected with ions, and the water -soluble chlorine ion content of concrete, sand, gravel, cement, mixing water and other inorganic ion content is quickly determined at room temperature through the ions and chemical anti -jamming reagents. , So as to prevent premature corrosion of concrete reinforcement. The chlorine ion content measurement instrument is light, the body is small, the fuselage is small, which is convenient for users to carry and suitable for on -site detection.

(3) Comparison of Haisha and Hezha from specifications: The river sand used in buildings has certain specifications. In the process of sieved in river sand, it is generally divided into 4-8 mesh of river sand, 8-16 meters of river sand, 10-20 meters of river sand, 20-40 meters of river sand, 40-70 meters of river sand, and river sand Various types of 50-100 mesh, which refers to the number of sand particles in the one-inch round range. Haisha does not have such a fine and clear rules.

kind.

(4) Different from the feel different from Hai Sa and Hezha: Grab a sand and hold it in your hand and then pat it out. If it is not sticky, it is river sand.

(5) The difference between Haisha and Hezha: This is the simplest and most direct way. Asked it and found that it was river sand that was not salty, and the salty was Haisha. At present, there are also many Haisha who have passed down

For melody, we can soak the sand in the water for a while, taste the taste of the water, and the salty is sea sand.

(6) The difference between Haisha and Hezha in the ingredients: The main ingredients of the sea sand are silicon dioxide, the crystal phase is mainly quartz, the long stone and rock chips particles are relatively small, the content of Yunmu films is less and the grinding degree is also very good. river

Salmonic and silicon content is lower. There are more metal ions such as calcium and aluminum.

But this is just an overall average situation, sometimes there are special cases, and it is difficult to have specific numbers

Overall indicator.

(7) Stir: Stir the weighted adhesive. be careful:

7.1 The order of feeding: Pour the weighted liquid component into the stirring barrel, then slowly pour the powder into it, and stir with a hand -held mixer while pouring.

7.2 Making method: The speed is 300 rpm/min, stirring time: 5min, the mixing gun should be increased up and down until the stirring is stirred until the mixing is stirred (the adhesive is raised with a plastering knife, the effect of the adhesive is the best); Still for 2min, discharge the air bubbles and stir it slightly.

白色石材防护、加工、 施工方案

7.3 The accuracy of the material and the uniformity of the stirring directly affects the bonding effect of the final construction. It is recommended that the special person is responsible, and the stirring staff is equipped with a timer to control the stirring time.

(8) Twist and rub the stone slightly when pasted, and then gently knock on the rubber mallet to make the stone and the adhesive closely fit. You can observe whether the edge striped glue adhesive is compacted. Use horizontal ruler adjustment

The flatness and reserved seam width between the stone.

白色石材防护、加工、 施工方案

(9) Protection: Put the stone or press heavy objects within 3 days. After 3 days, use foam plates, plasma plates, cotton -wool products and other covers to protect it;

白色石材防护、加工、 施工方案

Adhesive stirring process

10. Clear seam: Use the handheld cutting machine to cut the gap to clean the bonding agent in the gap; use dust and the vacuum cleaner to completely clean the working surface; fill in the same color fillers as the stone, and use a shovel to fill the seams. The agent is scraped at the gap, and the scraping direction and the gap are 45 degrees. Press the filling agent into the gap to ensure that the filling is full and dense. This process must be filled with full: the standard is the standard. Otherwise, the collagen will shrink after curing, and it should be avoided within 24 hours of half a seam after grinding. 11. Practicing crystals

11.1 Early ground grinding: For places with high cutting mouths, first use the polishing machine to treat a slightly flat, and must be grinded over there, as much as possible to avoid the subsequent processes.

Drop the mill.

11.2 Cleaning stone surface: Use professional machinery with pores to clean brush (steel wire brush) to clean the dirt at the stone damage or break to ensure that the subsequent process is fully bonded and the stone is fully bonded. This step

The sudden is quite important: if the steel wire is not cleaned, the dirt in the stone damage cannot be cleaned,

Nature affects the adhesion of repairing glue and stones, which will cause the epidermis to fall off, which will reduce the repairs

quantity.

11.3 Early Grinding Treatment (No. 30-60): Use 12 professional stone flat mechanics to cut the stone due to deformation, paving, processing and other factors

Flat, and remove the holes through the first grinding, and create it for the latter pores and fine grinders.

Create conditions.

白色石材防护、加工、 施工方案

11.4 Rough grinding treatment (No. 36-50): Remove the excessive repair glue of the grinding grinding and hole repair process of the first grinding, further adjust the flatness of the grinding surface, and prepare for the lower polishing process. Standard: There is no scratch of No. 50! There is no residual repair glue!

11.5 Corner grinding treatment (referred to as repairing border): For large-scale machines that cannot complete the corner parts or the edge scratches left by the first grinding and the middle mill, use the corner-specific equipment Supporting role grinding machine) Corner grinding and polishing connection processing. Standard: There are no cuts in the corner! There are no wool and scratches on the edge!

11.6 Essential milling treatment (500-1000-3000): On the basis of the flatness of the first grinding and middle ground stone, the luster of the stone is grinded and prepared for the polishing process of the lower road. Process points: Starting the grinding film from No. 500 must be placed aside! Perform the edge! First polish the surrounding edges, and then grind the middle. The middle grinding method is the same as the middle grinding method. The edge of the edge must be noted that if you use the 220 machine to polish, you must move the machine from the back and let the machine workpad close to the wall. If you use a 380 machine, you must rely on the corner of the machine to approach the wall.

11.7 Polishing Crystal Treatment:

(1) Spray the K-2 crystal surface treatment agent on the ground, and apply it to the steel pad attached to the crystal surface processing machine. Except for dust.

(2) Spray the K-3 additive on the ground and apply it to the red pads attached to the crystal processing machine. test).

白色石材防护、加工、 施工方案

(3) Spray the crystal surface treatment agent K-2 on the ground again, and then apply it with a white polishing pad, and apply it evenly. The brightness is further improved until the gloss of the ground reaches about 90 degrees.

Step 4: Stone Maintenance Control

1. In the process of paving marble sections and broken marble sections, the operating regulations should be traces of cement and mortar on the dry cloth and pure marble surface;

2. Regular (ranging from 3 to 6 months, depending on the usage) to carry out stone crystal maintenance and maintenance;

3. When cleaning, a neutral cleaner should be selected to prohibit the use of acidic or alkaline cleaner such as toilet spiritual or alkaline cleaners to avoid chemical corrosion such as acid and alkali;

4. Daily cleaning is forbidden to mop water. Long -term contact with water will destroy the protection and crystallization of the stone surface, causing various stone lesions and pollution problems;

5. During daily maintenance, if you encounter slight pollution, if juice, coffee, sewage, etc., you can wipe it with a semi -dry towel, and then dry it with a dry towel.

6. Import and exit control: Stones at the entrance of the entrance pass through a large number of people’s stamps, physical friction and bruises of the soles of the feet, which will cause deep scratches. At the same time

Pollution problem.

6.1 Features of entrances and exits: The entrance is a channel connecting the interior and external environment of the building, and it is also the main channel for people and things to enter and exit. During the circulation process, it can cause pollution or damage to the ground stone,

There are the following factors:

(1) Research and statistics show that people who enter inside the building through the exit and exit from the outside world will bring 7 grams of dust under their feet, containing sand grains and various pollutants.

(2) In rainy weather, the flowing stamp brings a lot of water and pollutants.

(3) Unexpected pollution of various substances.

6.2 Control method: Basic control methods are achieved by increasing pads. But what kind of ground pads and how to place it can effectively achieve the effect of pollution control?

6.2.1 Selection and placement of ground pads:

(1) Sand scraping stage: Persons’ first two steps on the cushion from the outside. At this time, the dust and pollutants carried at this time reaches the peak. You must first absorb and remove most of the sand, dust, and pollutants. Selected: Rough mat. Through strong friction, the sand shaving effect is played, and most of the substances of the soles of the feet

Stay on the cushion.

(2) Dust -extinguishing stage: After the first stage, most of the large particles and pollutants are removed, but there are still quite a lot of floating dust. After using the first cushion, it will also make a small amount of dust on the soles of the shoe. Selected: delicate cushion. By adsorbing, remove the material and floating dust left in the first stage

(3) Dust stage: After the first two mats, it can remove most of the substances that affect the decoration and life of stone. But we still need to add a dusty mat to completely adsorb the dust.

Selection: The cushion made of fine fibers or ultra -fine fibers has a good adsorption effect.

(4) Rain and snowy weather: If it encounters rain and snow, you need to add an additional cushion to the cushion at the door. The cushion must be extended inward by 2 to 3 meters inward.

6.2.2 Skills for opening doors: Nowadays, most hotels and shopping malls use the design of “rotating doors+double -side doors”. In addition to the cushion protection, the reasonable opening and closing door can disperse the concentrated stomach of the stone in specific areas to reduce the degree of wear.

(1) During important activities: During the meeting, exhibition and other important activities, the people have a large traffic. At this time, three doors should be opened to play a role in diverting the crowd.

(2) Non -activity period: During the non -activity period, the rotating door is closed and two side doors. Open for 15 days as the weekly period, allowing the flow of people to pass through different areas, which can reduce wear and protect the effect of stone. This method is very common in hotels and malls.

(3) Wind -proof sand: Dust earth and sand, except for the flow of people, the wind and sand are also one of the main reasons. In the windy weather, pay attention to the door and window strict.

6.2.3 Prevention in advance, saving time and effort:

(1) Prevention of Winning: Lian glass material, hard mobile phone screen, we are also used to sticking to the protective film. Natural stone is prone to various problems such as scratching, water absorption, and lesions. Especially in and out

白色石材防护、加工、 施工方案

These key positions, do a good job of pollution control system in advance, instead of waiting for the problem before solving,

This is the most scientific method to solve the problem of stone application decoration.

(2) Maintenance of the cushion: Used for pollution -controlled cushions. If there are too many sand and dust, the use effect will be reduced. Therefore, it should be replaced and cleaned regularly to keep it clean and dry.

4. Disease treatment

Alkali Returnement Treatment Process

1. Broken water: The water to be broken here refers not only to see water, but the source of all water and tide. There is no universal method to find the source of water, and all possibilities need to be considered in order to comprehensively

Really eliminate the contact between stone and water. Drag to water, direct water source contact, water on the back of the stone

The source, soil are humid, rainwater, high air humidity, etc., all details must be considered.

2. Dry: Open the doors and windows to ventilate, dry naturally, and pull dry with a pulling machine. The greater the power of the drawing machine, the better, and the blower is blowing with the drums to enhance air circulation, floor heating, baking light or flame spray heating (cautious),, use cautiously),, use cautiously),, use cautious),, use cautious),, use cautious),, use cautious),, use cautious),, use cautiously),, use cautiously),, use cautiously),, use cautiously),, use cautiously),, use cautious),, use cautiously),, use cautiously),, use it with caution),, use cautiously),, use it with caution),, use it with caution).

Using lime moisture (use cautious), etc., according to the situation on the spot, these methods can be applied, and the purpose is only

One is to keep the stone completely dry.

3. Cleaning: First use a shovel knife to clean the serious part of the alkali return, and then wipe the surface of the stone with a dry rag (or with a Baijie pad);

4. Protection

4.1: Seal the seams of the stone with cloud stone gum or filling agent;

4.2: Use a bristles or soft cloth to apply the stone light increase agent (infiltration type) on the surface of the stone, about 20m2/L, keep it for more than 48 hours, wipe the surface of the stone;

4.3: Repeat it with a stone-enlarged gorgeous agent every other week. After approximately 2-3 times, Bai Hua can prevent Baihua from exuding again.

Pollution lesions treatment process

1. Differences of pigment pollution: Stone pigment pollution is mainly due to the residues caused by non -color pollutants into the pores of the stone, or because certain pollutants are stained with water, air, and stone itself. Generally, the types of pollution are roughly judged by the stain color and combined on the spot, thereby formulating a treatment method. For example, pigmented pollution in the office area, generally belongs to coffee, tea, tea, and ink, because this is in line with the characteristics of office workers; the same pollution situation, if it appears in the construction of construction, should be judged whether it is oil, rust, wood, wood, wood, wood, wood Pollution such as pigmentation. If it is a restaurant area, food, fruit juice, soy sauce and other pollution should be considered; if pollution occurs on the warehouse floor, it should be considered whether it is paint, oil, and wooden boxes. If in the toilet area, sewage pollution should be considered.

2. Method of pigmentation: After judging the source of pollution, cleaning becomes very simple. The principle of pigmentation is basically the same. It is mainly used to use chemical discoloration methods, that is, the molecular structure of damaging the pollutants, and then cleaning. It is strictly forbidden to use strong acids, strong alkali, or other destructive materials to clean the pigment pollution of stone materials. These cleaning materials not only remove the effect of pigmentation are not as good as professional cleaning agents, but also cause severe destruction of stone structures and materials, causing various other stone materials question.

Rust spots disease treatment process

1. Rust spots: stone rust spots can be divided into two categories: foreign rust spots and their own rust spots. Only by clearing the rust spots first can we take the medicine and formulate subsequent protection measures.

1.1 The main types of foreign rust spots are: welding, steel cutting, scouring of rainwater scouring, iron stacking, etc. The characteristics of foreign rust spots are generally very obvious, and can be judged according to the shape of the rust spots

Source of pollution.

1.2 The rust of the stone itself is caused by the high iron content of the stone, which is produced from the inside out. Generally, it is round, dot -shaped, and sheet.

2. The choice of rust spots governance materials: The principle of marble and granite rust removal is essentially different, and the product cannot be universal.

2.1 Marble rust removal material: You cannot use acidic substances, otherwise the stone itself will be severely damaged. The peroxide must be used as the main ingredient to restore the rust ingredients inside the marble to achieve the purpose of rust.

2.2 Granite rust removal material: Granite has a strong acid and alkali resistance. The rust removal agent can be used to decompose the material, which passes through acidic substances, and decomposes the FE2O3 in the rust to form a neutral salt analysis, so as to achieve the purpose of rust. 2.3 Auxiliary materials:

(1) Stone rust spots are often accompanied by other pigment pollution. Therefore, rust removal products must be used with pigmentation products to achieve good results.

(2) There are many stone pollution, which is easily misjudged into rust spots. If it is found that the use of rust removal products is not effective, try it.

Stone pigmentation products.

3. The implementation process of stone rust removal: The removal of stone rust spots must go through the three processes of “absorption, decomposition, removal”. This process is a process of repeated cycle. Generally, rust spots need to go through three cycles.

3.1 Absorption process: Stone has a small microporous structure. The absorption of rust removal materials is a slow process. It requires certain conditions and time to penetrate inside the stone. The degree of absorption of materials is the key to determining the rust removal effect. The location, temperature, and brushing method of the board have influenced the absorption process.

3.2 Decomposition process: After infiltrating the inside of the stone, the rust removal material reacts with the rust composition, which requires a certain time. The response order of rust spots in different depths and positions is different from the reaction order of rust removal materials.

Need to have enough patience. 3.3 Removal process: Apply it with materials that are easy to absorb, such as toilet paper, gauze, etc. to adsorb the rusty solution after the decomposition of the reaction.

4. Protection process: After the rust removal is completed, protective treatment must be done, and the infiltrated protective agent must be selected.

5. Stone rust spots treatment plan formulation

5.1 Prevention of Winning: Preventing the occurrence of rust spots is more important than using the best rust removal products. It should be advocated the concept of “preventing victory and governance”.

(1) Stones that are prone to rust spots are not used in places that are easy to contact with water such as pools, toilets; (2), after the stone paving is completed, it must be well protective.

5.2 Comprehensive consideration and right medicine: Different environments and causes, such as temperature, humidity, stone variety, paving position, rust spots formation time, surrounding conditions, etc., will have a direct impact on the processing process. Therefore, in addition to the use of high -quality rust removal products, other factors must be comprehensively considered in order to formulate perfect technical solutions.
