subject: Strengthen The Conservation Is Top Priority To Prevent Pollution Of Decorative Stone [print this page] For Stone Wall Building The reason for the piebald, water stains, yellow rust and other phenomena, the Beijing Municipal Construction Project Materials Association Stone Professional Committee and executive deputy director Shixue Li said in an interview. Currently used for exterior wall decoration of the stone, the basic construction techniques are used hanging, was the result of pollution phenomenon, there are many reasons. First of all, no matter Granite Or Marble , As there are some small stone pores. Because different types of materials, the internal chemical composition is different. When in the course of construction or installation is completed, in case of non-standard dry pendant from corrosion, or the natural environment such as acid rain and snow, and air attacks, such as sulfur dioxide and other corrosive gases, the pollutants through the stone surface of the micro- L larvae cause corrosion and pollution.
Beijing Construction Material Association Professional Committee of stone added to the Secretary-General Zhang Yun Mao Road: Granite And other stone, it seems extremely hard, in fact, in a sense, is also very fragile. For example, in mining, the technology used to cut stone iron Gaza. When processing a small iron powder, if not promptly washed away the pollution will result in stone. Transport links are also important, if the transport of coal wagon, in the not thoroughly washed after handling and continue to load the stone, then the transport process would certainly result in pollution of the stone.
Secondary prevention treatment China Stone Application
care expert Wang Yanhua Group, said in an interview: decorative stone now exists in China is still quite serious pollution problems.
About how to control pollution of the way stone, Wang Yanhua proposed the theory of secondary prevention treatment. He said: First, from the prevention of pollution control staff stone, stone by brushing Protection (Conservation) agent approach, eliminate the phenomenon of stone disease. Stone Protectant is like giving a shot, stone surface, brush the curing agent, equivalent to put a layer of invisible garments, you can prevent pollution of the invasion. There are many types of curing agents, to different species and parts of stone, choose a different formulation of the curing agent.
Wang Yanhua, for example: stone for the wall hanging techniques. Contamination in natural stone over man-made factors, dust, rain water is stone appears the main reason for rust spots. So, then select the repellant, should choose a waterproof product.
If the investment units in the building originally had decorative, can understand this point, moderate increase in investment in some of curing agent, will be a multiplier effect. Compared with the second into the future to the cost of pollution, about five times the gap.
Wang Yanhua pointed out: With the right choice, but had to correct operation. Talking about how to properly operate the problems Wang Yanhua as the four elements. The first stone dried; second curing agent into the volume; third maintenance cycle; Fourth, rolling, brushing, spraying, wiping must be uniform. Wang Yanhua that: as long as four points, the basic building stone walls can be eliminated stone surface when it rains, "Pan-flowers" phenomenon.
Stone protection industry to be standardized
According to Wang Yanhua description: As the stone protectants of solidifying material production is not a high-precision and advanced science and technology, a variety of Additive , Stabilizer of the formula easier to engage in, so although protective stone or a new industry, but now there are many units and individuals engaged in this industry, so inevitably the product mixed, market disorder phenomenon.
Wang Yanhua said: Stone protectants causing confusion in the market for many reasons, first, the owners do not understand the investor protection does not attach importance to the stone that can be high or low grade of products, virtually for a number of employees is not responsible for the creation of a " an opportunity. " Second, those who are blinded by greed, shoddy. There is the stone protection industry has not been a timely support for relevant departments. Related such as "Construction Fee", "construction professional level of qualification standards" still need to be established.
