With more and more extensive use of stone in the field of architectural decoration, the stone disease associated with it not only greatly reduces the decorative effect of the stone, but also shortens the service life of the stone. There are three main problems: First, some of the material inside the stone material and the atmosphere of the material formed by the chemical reaction; and the second is caused by increasingly serious air pollution; Third, due to improper installation of stone material in the construction method. The following explains the stone disease treatment method and stone care precautions for everyone. Common stone disease treatment methods Stone lesions are inevitable, but stone lesions are also common, namely water spots, white hua, rust spots, and efflorescence. This article will do a combing of these four common stone disease removal methods. Water spots: First of all, it is necessary to distinguish what is the cause of water spots (stains) quit. If there is a lot of water below the stone village (for example: after the pavement is completed, cut the ground with a cutting machine; the ground is full of moisture before paving; after the installation, a large amount of water is infiltrated from the joints), so that this should be The dry peak-like cement layer is saturated with water, and the ground should be air-dried. After a long time of natural drying, the moisture in the layered cement is evaporated and the stone itself is treated. . If blindly cleaning with chemicals at this time, it will often aggravate immersion. The reason is very simple. Cleaning is to use water, and water can never wash away. Only evaporation is reasonable. Some people use the method of warming, if you use hot air drying method is possible, but it is not suitable for a large area to use a lot; but the use of fire, light baking and other methods, the effect is not ideal, these methods are able to quickly improve The temperature of the stone surface cannot increase the temperature of the cement layer for a long time. The evaporation effect on the water will not be too obvious, but the negative effect will be great. Due to the rapid warming, the stone Peng will swell, and the cement layering will cause emptying phenomenon. Sometimes it will cause the stone to curl up and produce clippings. The consequences are difficult to control and it is not recommended. Bai Hua: 1. The main reason for determining whether Baihua (alkaline) is produced is whether water is caused by cement during stone construction or due to wall leakage. If it is caused by water leakage, the source of the leak should be blocked first, and then the clean-up work of Baihua (alkaline) should be carried out. 2. Baihua (alkaline) can be treated with Baihua scavenger. Baihua scavenger has a corrosive effect on the marble surface and should be used with special care. 3. Before the treatment of the white stone of the smooth stone, you can use a marble blade to clean the thick part and then treat it with the white scavenger. The rough surface of the stone is uneven and the surface is difficult to clean. It is recommended to brush white. After the Chinese scavenger is used, it must be allowed to fully react (the color of the medicine is changed from colorless to green) and then brushed with gravity using a wire brush. If one time is not enough, it can be repeated several times until it is completely cleaned up; the pan-alkali treatment can be directly applied to brush white scavenger for treatment. 4. After the white stone (alkaline) on the stone has been cleaned up, apply a high-quality curing agent to treat the surface and crevices of the stone and then use a waterproof sealant to seal all the gaps. Eliminate Bai Hua again. Rust spot: The first step is to scrub the surface of the stone and remove the dirt that has penetrated into the interior of the stone. After that, apply a rust remover. Marble rust remover, rust removal effect is slow, heavy rust must be cleaned after 5 times to remove. If the construction period is shorter, granite rust remover can be used. It has a corrosive effect on stone stone, so it can be diluted to 1 times and can be used above. Severe rust trace can be removed only after 2 passes. The second step is to clean the stone with clean water until the surface of the stone is dry and prepare the stone colorant. When using colorants, follow the instructions for dilution. Diluents may also be used as appropriate. The third step is to paint colorants and protective agents. Coloring agent brushing requirements uniform, brushing after standing for more than 2 hours until the surface is dry and wipe the surface floating color. Check if the coloring is even. If it is found to be uneven, it should be repeated. After confirmation, apply a brightening type stone protective agent and wipe off the surface liquid after 2 hours. Alkaline: 1. As soon as possible on the board seam, the surface of the board and other comprehensive waterproof treatment, to prevent the continued invasion of water, so that ubiquitine will no longer expand. 2. Available stone pan-alkali cleaning agent on the market. The cleaning agent is a colorless translucent liquid made of a non-ionic surfactant, a solvent, etc., and has a certain effect on the cleaning of part of the natural stone surface. However, before use, you must first make a sample test block to test the effect and decide whether to use it. Stone maintenance precautions 1, non-neutral cleaners should be used with caution Stone is afraid of the strong acidity of the liquid, in the cleaning of the stone can not be ignored for the cleaning agent composition. General cleaning agents contain acidity and alkalinity. Therefore, if you use a cleaner with unknown ingredients for a long time, the surface gloss of the stone will be lost. In addition, the non-neutral chemical residue on the stone is also the main cause of stone lesions in the future. 2, waxing need to be carefully selected There are a wide variety of waxes on the market, including aqueous wax, stearic acid wax, oily wax, acrylic wax, and the like. These waxes basically contain acid-base substances. Not only will it block the capillary pores that the stone breathes, but it will also be stained with dirt to form wax scales, which will cause yellowing of the stone surface. When waxing is required in locations where pedestrians and goods are frequently circulated, professional maintenance companies must instruct waxing and maintenance methods. 3, ventilation and dryness is a magic weapon to maintain natural characteristics Stone is afraid of too much humidity in the environment. Water vapor will produce hydration, hydrolysis and carbonation of the stone, resulting in water spots, whitening, weathering, erosion, rust and other diseases, destroy the stone, so the installation of stone should always be kept dry and ventilated. 4. The variety of protective agent must be selected After the construction of the stone is protected, it must be able to maintain the permeability of the stone and waterproof, anti-fouling. Do not use the unknown protective agent to avoid not only failing to achieve protective effect, but increasing the difficulty of stone maintenance. 5, clean and clean to adhere to do a good job Whether hard granite (hardness HRs88-1114-7) or soft marble (hardness HRs46-773-5) is not resistant to the long-term turbulence of wind sand and soil particles. Therefore, it is necessary to use dust collectors or electrostatic mops to do a thorough job of dust removal and cleaning. The entrance to the commercial space is best able to place a dust mat to prevent the sand particles on the shoes from scratching the stone. It is advisable to change the wearer's sandals after entry to reduce the dust abrasion on the stone surface.
