the building tone material surface stained with dust
Abstract: Nowadays, with the rapid development of china’s economy and the increase of people’s living standard, China’s construction industry has made a rapid development, at the same time the quality of urban construction and decoration demand have made a great improvement, besides that the pursuit of beautiful and luxurious and the advocate of return to nature have become a kind of trend of architecture art and decoration art. Compares with the cement, wood and plastic construction and decoration materials, nature stones have become more and more favorable to the owner and designer for its unique property. What’s more, the nature stones’ application has become more and more widely and its usage amount has constantly increasing in the field of architecture. As a main aggravate of beton, nature stones could used as stone pillar, stone mat and so on in the structural engineering ; as a sort of plane material, nature stones could used in the stone carving decoration and industrial construction. However, because of the environmental pollution, the quantities of solid particles in the air are increasing rapidly, which lead to the outstanding dust pollution of the building surface; the paper mainly discusses the mechanism of building surface stained dust and the protection schemes.
The paper first studies the protection status quo of the nature stones. Nature stones protection has been developed 30years abroad while it just beginning at home.
Next, the paper studies the mechanism of building surface stained dust. When the building is exposed in the air, the dust particles will be constantly stained in its surface. If there is no external action, it is difficult to pull the dust particles away from the surface adhesion. Why the dust could be stained in the surface of the nature stones? What kind of action are they receiving? How many factors are they influenced? The paper makes a detailed discussion of above questions.
Last but not least, the paper studies the protection scheme of the stones surface. Through the studies of the physical surface dust removal machine, the article puts forward the protective scheme of building stone, which is mainly involves four aspects: do regular maintenance, choose the appropriate nature stones care equipment and nature stones protective agent and timely processing nature stones disease.
