Coloured sand in coloured sand epoxy floor refers to coloured quartz sand, not other types of sand. The reason why quartz sand is chosen is that quartz raw materials come from a wide range of sources and have high mineral hardness, which makes the raw materials and quality of the floor have a fundamental guarantee. Quartz sand is colorless or white. Through new dyeing technology, quartz sand particles can be processed into colorful sand grains with rich color. With the mixed decorative design of colored sand, the floor is endowed with colorful aesthetic feeling. Quartz sand should also be round or spherical granular, so as to facilitate the free sliding between particles in the construction process, so that the sand can be as close as possible, "the most compact accumulation", so that the epoxy color sand layer is fully dense, to ensure the floor excellent pressure resistance and wear resistance. In addition, when the epoxy coloured sand layer is fully compacted, the amount of resin used in the surface layer can be saved and the cost can be reduced. 閫夋嫨濂界殑褰╄壊鐭宠嫳鐮傚�瑰僵鐮傚湴鍧�鐨勯珮璐ㄩ噺鑷冲叧閲嶈�侊紝杩囧幓楂樿川閲忓僵鐮備富瑕侀潬杩涘彛锛屼竴浜涘�栬祫浼佷笟鐩存帴浠庡浗澶栬喘寰椼�備絾鏄�锛岀幇鍦ㄥ浗鍐呭凡鏈夊巶瀹惰兘鐢熶骇楂樺搧璐ㄥ僵鑹茬煶鑻辩爞锛屽�傚寳浜�瀹濊幉绾冲叕鍙哥敓浜х殑褰╃爞锛屽叾鑹叉辰銆侀�楃矑鍦嗗害銆佺矑搴﹂厤姣斿強鑰愬寲瀛︽�х瓑鎸囨爣鍧囦笌鍥藉�栦骇鍝佺浉褰擄紝璐ㄩ噺绋冲畾鍙�闈狅紝涓嶄粎浠锋牸杈冧綆锛岃�屼笖渚涜揣鍛ㄦ湡鐭�銆佸敭鍚庢湇鍔″ソ锛屽凡涓哄�栬祫鍏�鍙告墍閲囩敤鎴栦负鎸囧畾鐢ㄧ爞銆�

Choosing good color quartz sand is very important to the quality of color sand floor. In the past, high quality color sand was mainly imported, and some foreign-funded enterprises bought it directly from abroad. However, now domestic manufacturers can produce high-quality color quartz sand, such as the color sand produced by Beijing Baolianna Company. Its color, particle roundness, particle size ratio and chemical resistance are comparable to those of foreign products. The quality is stable and reliable. Not only the price is low, but also the supply cycle is short and the after-sales service is good. It has become a foreign capital. Sand used or designated by the company.

The price of coloured sand epoxy flooring is higher than that of self-leveling epoxy flooring, as in the past and now. The basic reason is that the material cost is higher and the construction technology is more complex. In order to reduce the cost, some companies in South China have tried to replace coloured quartz sand with coloured sand made from natural stone waste (which contains carbonate rock), but the quality of coloured sand floor can not be guaranteed. First of all, the wear resistance is not qualified. This kind of natural coloured sand has complex composition and different hardness. It is generally suitable for wall decoration, but not for floor decoration. Now there are poor quality color quartz sands on the market. The grains are not rounded, there are edges and corners, the dyeing is not uniform, the color bonding is not strong, and the color fades easily. It is the product of mixing ordinary quartz sands with some color coatings. The manufacturing process is simple, not professional, and the quality is easy to be problematic. Please pay attention to the construction units.
