Crystal surface treatment is currently an ideal stone surface maintenance method, which is a chemical process. The principle is to use the crystal surface treatment agent plus the crystal surface treatment machine to rub the stone surface. Under the dual action of chemical and physical, the surface layer of the ground forms a hard and dense crystal hard crystal layer, so that the stone surface is not easily damaged, and it is not easy to be Sticks stains to ensure the essential properties of the stone. In other words, the crystal layer separates the source of pollution from the stone, and the only layer of crystal on the stone is contaminated and damaged.
Because the core element of stone surface treatment is to form a dense crystalline hard treatment layer through a certain temperature and a certain agent, the machine for stone surface treatment must have the following three key elements.
One: temperature, the appropriate temperature for stone crystallization is about 60 degrees.
Two: When doing crystal face treatment, the machine must reach a certain speed to heat the heat to 60 degrees. The suitable speed is about 220 rpm.
Three: The right weight, most of the crystal surface treatment machines currently on the market, the speed can only reach about 170 rpm, so the friction can only be strengthened by increasing the weight, and it is suitable. temperature. The counterweight is too heavy, which is not conducive to machine operation, and the counterweight is too light to achieve the desired crystallization effect. According to the manufacturer data of the world's top production crystal surface treatment machine, the machine weight is about 60KG. The material such as wax water is consumed repeatedly, and the wax water is mostly alkaline, and the marble is rapidly deteriorated due to corrosion of calcium carbonate. Granite quartz is highly resistant to corrosion, but feldspar and mica are not resistant to corrosion, so the pitting is constantly deepening and deepening.
Waxing is a form of protection used in the past, it is a physical process. Simply put, a layer of covering (wax) is applied to the floor to protect the floor surface. Daily maintenance will only be the cleaning and maintenance of the covering (wax). This covering method does not reflect the natural texture of natural stone and has a short service life. Waxing should be waxed regularly, constantly
The stone crystal surface does not change the structure of the stone, nor is it coated with a layer of covering, so it does not change the texture of the original stone. After the crystal face treatment, the stone surface molecules are denser and the gloss brightness is obviously improved, making the stone surface brighter and more noble. The crystal face treatment accumulates its effects and value during the continuous care process.
So common stone curing methods
First, the stone surface treatment
(1) Tools: Multi-function weighting machine (17T model), water-absorbent vacuum cleaner, 3M red P polishing pad, 3M white polishing pad and various steel wool.
(2) Pharmacy: K2, K3 crystallizing agent, various crystal powders.
(iii) Steps:
The stone has been used or used for a few years. In order to prevent the surface layer from aging and prevent the stain from penetrating into the inner layer of the stone, the wear resistance is enhanced and the appearance is seriously affected. The crystal hardening treatment is carried out by liquid crystallizing agent or powdery crystal powder to chemically react with the calcium component in the stone to form a new layer of crystallized material on the surface of the stone, so that the stone reflects the natural luster to achieve A certain hardness and brightness. In particular, natural stone itself contains strong radiation, which will cause great harm to the human body. The main function of crystallization treatment is to greatly reduce the radiation contained in the stone itself.
There are two types of crystallization treatment systems, one is liquid crystal and the other is powder crystal powder.
Liquid crystallizing agents are the most commonly used agents, and K2 and K3 are a two-in-one crystallizing agent. K2 is a pink liquid containing particulate matter. Its main function is to clean the surface sludge and increase the brightness. First, spray the pharmacy on the ground to be treated, then pressurize the wire surface with a weighting machine (17T model), and evenly polish the agent on the ground until the K2 is polished to form a film, so that the surface of the stone is clean and the brightness is reached. Ideally, if you don't achieve the effect, you can repeat K2 again. Then sprinkle K3 on the ground that has been worn over K2. The main function of K3 is to increase the hardness and wear resistance of the stone surface. It is also polished on the ground by the weighting machine, and the K3 is polished to form a transparent protective film. This method not only protects the surface of the stone, but also increases the brightness by 20-30 degrees on the original basis, especially in marble marble.
Powder crystal powder, also known as polishing powder. There are many brands and types, so there are many different colors of crystal powder, but they are basically the same. The main function is to clean the sludge on the stone surface and increase the brightness of the stone. Usually used in terrazzo, artificial marble, sandstone, microcrystalline stone and other stone. The operation method is to use a weighting and polishing machine, generally pressurizing the red 3M brand wool polishing pad, and then spraying the crystal powder and water on the ground to be treated at a ratio of 1:10. The ideal effect of grinding is generally increased by 20-30 brightness. .
(4) Notes:
Daily cleaning work is done every day according to different needs, and the dust is kept clean at regular intervals. Do not use a black wax pad to polish. When cleaning, use red and white scouring pad to clean. Avoid using floor scrubbing brush. The irregular pressure and hardness of the ground brush can easily wear the ground.
Second, stone renovation treatment
(1) Equipment used
Special tools such as stone refurbished machine, multi-function weighting machine, vacuum suction machine, counterweight iron, various types of diamond grinding discs, 3M polishing pad, and various accessories.
(2) The medicine used:
Stone protective agent, stone crystallizing agent, stone crystal powder, K2, K3 brightening and hardening agent and other stone special chemicals.
(3) Steps:
a) No matter what stone, you must make a model before renovating it, and then draw conclusions on the stone according to the effect of the slate.
b) Begin large-scale renovation, and it is recommended that Party A waterproof the stone when necessary.
c) Marble joints, using marble joint glue, fill the gap between the paving stones with the same color of glue, so that the stone achieves the effect of integration, increase the beauty of the stone, and achieve seamless treatment.
d) Start grinding the thickest 50th, and the 50th grinding must be smoothed, mainly grinding and cutting, the time is long, the place with extra large cuts should be handled separately by hand throwing machine, when grinding with hand throwing machine, Pay attention to his flatness, pay special attention to the pit.
e) No. 150 and No. 300 are normal grinding, as long as the grinding is uniform, it is fine. But you must pay attention to the grinding in place, there can be no leaks.
f) No. 500, very important. This time, the grinding number is to make the stone the most basic light, so it must be polished evenly and for a long time, so that the basic foundation of the gloss of the stone can be laid.
g) No. 1000 and No. 2000 are also normal grinding, as long as the grinding is uniform, it will be fine. But you must pay attention to the grinding in place, there can be no leaks.
h) No. 3000, the last time, the polishing time should be long, and the water should be put a little more, so that the work of the stone renovation part is finished.
i) If necessary, give some marble (marble) a special light block grinding process. The special light block is a compound synthesized from calcium oxalate. When you polish the special light block, pay attention to its length of time, the amount of water, and the flatness. When holding the machine, grasp the smoothness and polish evenly. After polishing, you must use a polishing pad to add water and wash it again. Otherwise, the leftover oxalic acid will affect the gloss of the grinding.
j) After finishing the above work, the stone renovation work will be finished. After cooling for 24 hours in a ventilated environment, you can do the post-crystallization maintenance work.
k) Note: The grinding technology adopted above is the grinding number of Jiali B-grade grinding disc. If it is very advanced or special stone, or the customer requirements are very high, you can choose Jiali brand special film, model number For: 60#, 120#, 220#, 400#, 800#, 1800#, 3500#, special light block, the grinding process is basically the same as above.
L) The above is just some basic stone renovation process, mainly the material, characteristics, performance, origin, and stone-specific minerals of the stone on the construction site.
(4) Effect:
The surface of the stone that has been refurbished and crystallized has no impurities, and the brightness reaches 90 degrees or more, and the hardness is obviously increased by 2-3 Mohs hardness.
Third, stone lesion treatment
The main lesions of stone are caused by oil stains, water stains, coffee stains and other colored stains that penetrate into the stone. There is also a lesion caused by minerals contained in the stone after being damp or blistered, and generally has a series of lesions such as anti-yellow, anti-alkali, and anti-rust. The stone is subject to external factors, and its performance and color will be affected in various ways, and the decorative effect will also decrease. The reason is that the harmful ionic solution passes through the water as a carrier to freely enter and exit the capillary pores of the stone, and participates in the chemical reaction of harmful substances to form a stone lesion.
Common stone diseases include rust yellow spots, organic spots, white spots, wet spots, chemical corrosion, oil spots and oil stains, loss of light, powdering, shelling and peeling. For the treatment of the lesions, the special professional imported agent is used to remove the lesions, and the method of the construction site is removed to draw conclusions, so that the stone can be restored to its original color and achieve the desired effect. We generally repair stone conditions by physical or chemical means.
(1) Chemical treatment of illness - professional cleaning:
Professional cleaning of stone is the use of chemical methods to clean and maintain the dust or other pollutants on the stone surface. The preferred method for rust yellow spots, organic spots, white water, water spots, oil spots and oil stains is professional. The method of chemical cleaning. If there is a loss of light on the surface of the stone, peeling of the shell, holes, cracks, etc., it is necessary to use a physical method - stone renovation.
Professional cleaning construction process:
1. According to the material of the stone, use professional cleaning agent to spray the cleaning agent on the surface of the stone to let the cleaning agent and the dirt molecules act to absorb the residual dirt on the stone.
2. When the stone is cleaned to the desired effect, it is necessary to further dilute the cleaning agent to the stone microporous suction residue, and repeat it many times to prevent the disease from happening again.
3, stone cleaning after natural drying, stone protection, allowing the protective agent to fully penetrate into the interior of the stone, and form a water-blocking protective layer to achieve the function of preventing disease.
(b) physical treatment of the disease - refurbishment or repair:
If the shell surface is peeling off, holes, cuts, hollow drums, cracks, it is necessary to repair or refurbish the treatment. In order to prevent the above-mentioned symptoms from occurring during the use of the stone, the best treatment method at present is to refurbish the stone, usually by physical and chemical methods.
Fourth, stone protection treatment
Stone waterproofing is a general term, and it can also be called stone protective agent. It can prevent many substances from invading the stone, or colored stains penetrate into the deep layers of the stone to produce diseases. The most common ones are: water stains, oil stains, stains, coffee stains, and other colored stains.
There are two types of stone waterproofing systems: oil-based protective agents and water-based protective agents. There are many common types, and the methods of use and protective functions are basically the same.
Oily protective agents are generally used for rough-faced stone, such as various fire-burning boards, stone, bluestone, travertine, etc. Before painting, the dust on the surface of the stone must be cleaned first, until the water inside the stone is completely dry. So that you can brush the protective agent, then use a brush to evenly apply the protective agent on the surface of the stone, generally brushing 2-3 times. Special stone needs special treatment.
The water-based protective agent has a wide application range and is an organosilane type oil solution body which can penetrate into the depth of the stone by more than 8 mm to form a firm network water-blocking protective layer and effectively protect the substrate for a long time. It has many functions such as waterproof, moisture proof, anti-fouling, acid and alkali resistance, anti-aging and anti-mildew. In particular, the alkali and salt resistance functions are even better. After use, it does not change the color of the stone and protects the breathability of the stone. It is a protective agent of choice for transparent, colorless, non-strong odor buildings and artifacts. It is suitable for the protection of natural stone, artificial stone, ceramic, brick, cement and other pore materials, but it is not recommended for sandstone and other similar substrates.
