Brief introduction of carborundum filter material: carborundum, SiC, also known as silicon carbide. Pure is colorless crystal. The density is 3.06~3.20. The hardness is very high, about 9.5 degrees Mohs. Generally, it is colorless powder particles. After grinding, it can be used as grinding powder, polishing paper and Grinding wheel And the friction surface of the grinding stone. It is made by putting sand and proper amount of carbon in an electric furnace to strengthen heating. Natural emery, also known as garnet sand, is a silicate mineral. Abrasive materials made by hydraulic separation, machining, screening and grading. The emery filter material has a long history of production and use, and emery grinding has been used in ancient China crystal Glass , various jade History of. The 1840s are far away pin Toyo. The emery filter media can be divided into three categories: coarse, medium and fine. The coarse mesh is black red, the middle mesh is light red, and the detail mesh is red white. All mesh sizes have uniform particle size, uniform particle shape, angular crystals, sharp edges, and high grinding force. For stone industry grinding marble and other soft materials. Glass industrial grinding glass burrs, TV picture tubes, optical instruments, lenses, prisms, clock glass, etc. Metal industrial sand blasting, rust removal, grinding. It is used for grinding offset plate in printing industry, processing plastic samples, leather, sandpaper, etc. in light industry. The grinding force of natural emery is slightly lower than that of electric furnace white corundum, but it is capricious and has the characteristics of shell shaped section mouth. Its advantages are high smoothness of grinding parts, few sand marks and shallow sand marks. The grinding surface is fine and even, which can improve the product quality and is the unique feature of emery. The grinding time of natural emery is short, the benefit is high, and the price is low, which can make up for the short life.
Pure natural emery is suitable for sand blasting, rust removal, polishing and other purposes. It is widely used in electronics, microelectronics, communication, computer room, optics, biochemistry, pharmacy, food, printing, chemicals, health equipment, accurate machinery, electroplating, plastic hardware, various spraying workshops, automobile manufacturing and other industries.
