In recent years due to the deterioration of the natural environment, dust, industrial waste gas, vehicle exhaust gas, acid rain and other pollution, more and more serious, easy to cause the pollution of building stone.The following will building stone material to introduce the maintenance of common sense knowledge.

Building stone once contaminated, very not easy cleaning.If you use bad cleaner, forcibly remove blotch, extremely easy damage of stone material, accelerate the degradation of stone material.A modern building, in addition to improve the structure of the design, the whole appearance of the maintenance also nots allow to ignore.Domestic stone used in construction within the exterior wall decoration increasingly widespread, for stone material maintenance also increasingly cause the architect, construction company and owner from three aspects.

Some problems raised often in general are: stone wall seepage, hua, rusty spot, blotch of pollution, water pollution, oil stain, construction materials, weathering, aging, and access to burnish the wear, and so on.According to the above problem, can adopt the following maintenance methods stone disease prevention and management.

Due to the building came to pivot, relatively pollution is especially serious.Because of stone material itself has wool stoma and water imbibition, air pollution, dust and acid gas in the air, vehicle exhaust, etc., accumulate over a long period to attached to the stone material surface, when it rains, will accelerate the pollution of acid rain erosion of stone material and adsorption in stone wool stoma, cause not easy cleaning blotch, especially for the fire stone, the faster of the pollution, and it is not easy to wash, the use of commercially available cleaning agents can not only remove the pollution;If smooth stone, the luster eroded away soon.To remove these pollution, therefore, can use stone material is special cleaning agent, have strong scavenging agents usually used or clearing agent such as stone dedicated multi-function detergent.This kind of stone material is special cleaning agent can penetrate into the pollution completely remove inside the wool stoma, and won't hurt stone.If you want to prevent stone once again by the pollution, in the stone after clean, in the case of the stone surface drying, again make a protective processing work, the permeability of the protective agent commonly used some multifunctional protective agent or stone material is special protective agent, this kind of protective agent can penetrate stone, form a protective layer, a waterproof, anti-fouling, prevent rusty spot, prevent oil, weathering, prevent aging, resistant to acid and alkali, tea, coke, causing the blotch effect such as soy sauce, and can effectively control the generation of hua, and do not hurt the original permeability, stone cleaning water wipe effect could be achieved, usually don't require the use of other cleaning agents.

Prior protection of external wall pollution treatment: in general, stone walls were very high, come again after cleaning, once the pollution caused by the construction great inconvenience.If can do a good protective treatment in advance, after the completion is no pollution problems, the daily work of cleaning the also just can wipe with water, and the protective treatment before the construction cost is low, construction is more easily, more economic.

After the completion of the stone material, after a long time will not always have dry the wet trace on the surface, which is commonly known as water spots.To remove water spot, is very difficult, because the formation of the water pollution is very complicated, including cement, acid rain, hua stone, sand, and pollution of the earth.The pollution cause the deterioration of stone material itself, changed the nature of stone material is rather easy to clean, so for water spots, the only way is to prevent.To prevent the formation of the water pollution can be used before the construction of multi-function special protective agent or stone protective agent.Before construction, to the stone protective processing, can effectively avoid the formation of water pollution, and can achieve good antifouling effect.

We often see some white crystal out stone in the seam, which is commonly known as "hua" (whiskering).Hua is divided into two kinds, one kind is "hua", is a kind of "secondary hua".The cause of the "hua" is the construction of the cement mortar to produce chemical changes in the formation of calcium hydroxide, come out from the stone seam or from grain, wool stoma stone material itself, and carbon dioxide from the air to form white crystal;"Secondary hua" is mainly due to the rain infiltration internal contact with cement mortar, stone material produces chemical changes and form hua.Both kind of hua phenomenon, to use powerful remover to remove.In general, to remedy and prevent hua regeneration must begin from many aspects.First to prevent the external pollution of rainwater infiltration, this is the stone material surface protective treatment and strengthening the caulking portion of the waterproof function to begin, as long as the water is no longer into stone outside, also do not have moisture inside the stone material, hua is unable to regenerate.
