Berson Rizhao City, Shandong Province Building Materials Technology Co., Ltd. (www.cnbsfs.com) is located in Rizhao City, Shandong Rizhao Rizhao City, a new urban Jinan City Garden Road 17-A, Contact: Lin Dong many factories laying the ground floor appears aging, cracking and other phenomena, it is because destroying the external environment, or their own qualitative change occurs it? Actually, the reason these two have toxic emery flooring manufacturers, and even the human factor. Sunshine Emery floor damaged some of the external environmental factors factory floor is laid in the open space environment, which makes it vulnerable to the effects of wind and sun, thus exacerbating the ground aging. Emery floor is also the essence of cement products, it is the high-grade cement with different levels of silica sand mixed product nontoxic Emery floor construction, it certainly has the characteristics of cement products: Ca + Mg + free states of ions from the pores caused by non-stop precipitation dust generation; cooperation with the loss of the last of hydration water, resulting in a lot of toxic Emery floor pores, thus causing not dense, so its strength and durability are greatly reduced due to the thickness of the silicon carbide is generally 3-5 mm, very easy to fall off, if the next time did not master the material. After the thickness of this layer is worn, the following will be the beginning of gray cement, it is often in the use of the floor a year later, even with waxing maintenance, it is inevitable scratches and wear.
