Stone surface contamination and against

First, pollution and erosion of the stone surface

      People choose decorative landscaping stone, the main reason is for beauty, but now almost all of the country due to previous installation used directly without surface treatment, a long time, due to the stone itself reason or process from outside influence or cause the formation of stains, rust, discoloration, peeling and other drawbacks common, even ubiquitous. This greatly affects the appearance, which should be valued lower. Therefore, decorative stone installation before construction or during use of the surface treatment is extremely important. Foreign decades ago to carry out research in this area, and have devised various methods of surface treatment, while China is just in its infancy, it is necessary to strengthen work in this field. http://www.stonegroupon.com/

      Second, several common symptoms and causes of pollution violations

      stone tile saw cutting through the sand into a rough board, face flushing with water if not clean, more or less stick with iron, longer storage time, the wool board surface rust. Air of carbon dioxide, sulfurous acid gas dissolved in the rain, will corrode the marble stone to lose their luster.

      Because the stone has a fine pore water to penetrate, so that anchor rusting steel, iron leaking, causing rust. Wet paste installation, sheet metal and concrete in contact with water leaking alkaline solution stone surface, after drying, often forming a basic crystalline substance attached to the surface of the stone, the so-called anti-base phenomena (Bai Hua), commonly known as " drip nose "," tears ", the stone pollution discoloration. For the kitchen, the bathroom, stairs, handrails, etc. due to exposure to various oils or dirt to form traces of oil or stain. Stone products due to improper packing straw, damp or wet was, could easily lead to spots, especially by sea erosion during transport, easier to form discoloration. Stone wool characteristics and the evaporation rate is a key factor in the stone straw erosion rate. At higher temperatures or stone surface in direct sunlight, eroded faster, accelerating its surface discoloration. Because the stone pores, cracks must have access to water, causing ice cracking, cold and heat changes in the temperature difference between day and night can also cause the stone to crack. Stone encounter moisture qualitative distribution of soluble salts, in particular will be subject to abuse, so the beach stone, because the salt solution dry, wet wind erosion change, make it easier for the stone discoloration. Corrosion. Organic growth, such as moss, fungi, algae color, lichens, etc., so that the stone surface form a variety of spots, the city some organic matter in order to survive, had to sulfide, nitrogen oxide and carbon dioxide in the air as protest, and will change the texture of the stone.
