Granite Stone conservation Wikipedia

  
    In recent years due to the deterioration of the natural environment, dust, industrial emissions, motorcycle exhaust, acid rain and other pollutants, the construction of stone used easily polluted. Stone once contaminated building after cleaning very difficult. If you use bad detergent, and forcibly polluted pots removed easily hurt Stone, Stone accelerate the deterioration. A modern building, in addition to improve the structural design, the entire exterior maintenance should not be overlooked. Domestic construction of the stone used in external wall decoration is becoming increasingly popular, the conservation project for Stone also increasingly aroused architect, construction companies and owners of three attention.
    Generally speaking frequently encountered problems: the external walls of water seepage Stone, Bai Hua, rust, polluted pot, water grouper, oil spots, the pollution of construction materials, weathering, aging, and personnel access caused luster wear, and so on. To address the problem, the Company provides the following types of treatment and preventive conservation method for your reference.
    As Tower ranks to the drive, relatively polluted. As Stone itself caps and absorbent, air pollution, dust with the sour gas in the air, motorcycle exhausts, and other sources over the stone to attach to the surface, when it rained, the acid rain pollution will accelerate the erosion of the Stone of Stone and adsorption in the small caps, caused not easy cleaning the polluted, especially in the face of Stone fire, the formation of such pollution faster, not easy cleaning, use only commercially available detergent can not remove these pollution; If the stone smooth, shiny will very quickly be eroded swap. Therefore, in order to remove these pollution, can be used for cleaning agent JSC Stone, commonly used by JSC powerful scavenger, or JSC - scavenger, such stone dedicated cleaning agent can be infiltrated cap the pollution completely removed, and will not damage the stone. If Stone once again to prevent contaminated, it can clean the stone after stone surface dry in the circumstances, a further protection of action, the permeability of such a commonly used protective agent JSC-protective agent, JSC15 of Stone protective agent, which can be protective agent infiltrated several internal Stone , the formation of a protective layer, a waterproof, anti-pollution, anti-rust spots, anti-oil pollution, wind-proof, Anti-aging, Acid and Basic Resistance, Anti-tea stains, cola, soy sauce, and so the oil spots results, and to the formation of a controlled Bai Hua, without loss and permeability of the original Stone, the normal cleaning Wipe water for only effect can be achieved without the use of other cleaning agent.
  
    Prior external pollution protective treatment: Generally speaking, are that a stone wall of height, once after the cleansing of pollution, construction very inconvenient. Prior can do if protective handling the case, not after the completion of the pollution problems, day-to-day work of cleaning wipe can only water, and the protective pre-construction costs low, the construction more easily with more economical. Commonly used a JSC multifunctional agent, JSC15 of Stone protective agent, a revolutionary breakthrough in the past to improve the protection of wasting time and effort dealing with problems, the current method abroad has been widely used in stone projects.
    Stone completed, after a very long time will not dry, and always left water marks on the surface, which is commonly known as water grouper. To remove water spots can be said to be very difficult to do so because of the formation of water grouper complex, which includes cement, acid rain, Bai Hua, sandy bad, and self-absorption Stone underground pollution, pollution of metamorphic stone itself, such a qualitative change is not easy Stone cleared Therefore, the water grouper, the only way is prevention. To prevent the formation of water spots before construction can be used in multi-functional protective agent JSC Stone or JSC15 of protective agent. Before construction of a protective stone processing, can effectively prevent the formation of water spots, while the anti-pollution can be achieved good results.
    We often see some white crystals in the joints from Stone flow out, and this is called "Bai Hua" (Pan-alkali). Bai Hua divided into two types, one is the "first Bai Hua", a "secondary Bai Hua." "One Bai Hua" is caused by the construction, cement mortar undergo chemical changes formation of calcium hydroxide, from Stone in the joints emerge from the stone itself or the texture, caps Department emerge, and the carbon dioxide in the air with a white crystals; "Second Bai Hua," mainly due to Stone internal rainwater infiltration contact with cement mortar, undergo chemical changes and the formation of Bai Hua. Both Bai Hua phenomenon can be used JSC powerful scavengers to remove. Generally speaking, it is necessary to remedial and prevent Bai Hua renewable required from different areas. First to prevent the pollution that is outside the infiltration of rainwater, which can be made from stone protective surface treatment and strengthening Sealant Waterproofing part of the function to proceed, as long as the water is no longer outside infiltration Stone, and Stone also without water, Bai Hua is not renewable.
