Use of Sichuan white sand
The effect of polishing and brushing wear-resistant materials with silicon powder is very good. Follow the progress of intelligent professional skills, and the surface solution of materials is also required to be higher and more precise. The application of wear-resistant materials is becoming increasingly common. Because its particles are close to the ring, the silicon micropowder is superfine crushed according to the extremely fine and grade classification, and then treated with modified materials. It is an excellent scrub wear-resistant material for metal products. If it is used in scrub rolling bearings, the smoothness can reach more than 3.0, better than similar imported products. Other products are used for polishing semiconductor material posts, fine gate valves, hard disks, magnetic tape drives, and cars.

The magnetic separation equipment removes iron according to the chemical properties of iron. The magnetic separation equipment has two methods, dry separation and wet separation, each of which has its own advantages. When it is used, the composition of raw quartz sand should be measured as far as possible. If the raw quartz sand contains hematite, limonite, biotite and other weak magnetic residues with intergrowth particles in it, the wet separation is the only way, However, the disadvantages of wet separation are large power consumption, easily damaged materials, large water demand for production, and high operation and maintenance costs. If the above residues are not available, dry separation can be used. Compared with wet separation, the cost and maintenance are extremely low.

Because of its advantages of good quality and low price, textured sand has been widely used in plastic, architectural coatings, paper industry and other industrial production. Using calcium bicarbonate as filler can not only increase the amount and control the cost, but also improve the electronic optics, thermodynamics, structural mechanics and other properties of plastic products, in which the structural mechanical properties are the key and basic properties. Calcium carbonate filled with plastics has a history of more than ten years. With the development of technology in recent years, it can not only control the cost, but also not significantly reduce the performance of products, and even in some levels, such as mechanical equipment, heat and other levels can be greatly improved.

It is not important that quartz sand is polluted by waste water environment. Sludge can itch or anaerobic respiration, dissolving pollutants in water. But for the fine quartz sand filter material, if the pure water is treated, it can be used for 2-3 years. Once the environment is polluted, it can be replaced immediately, otherwise the actual filtering effect will be seriously affected. Snow white sand is a kind of commodity for mining, production and processing. Natural quartz sand is widely used in people's daily life, which shows the necessity of natural quartz sand in the market. The precious network resources that can not be regenerated by natural quartz sand are not inexhaustible network resources. The actual effect of natural quartz sand filtration material in sewage treatment is excellent, and the market share will become smaller and smaller.
Use of Sichuan white sand
The flame retardancy of quartz sand can be indicated by its sintering point, that is, the temperature at which the test material is gradually melted and sintered. Sintering point refers to the temperature at which the surface of raw sand particles or the mixture between sand particles gradually melts. The sintering point test can be carried out in various continuous high temperature tubular heating furnaces, and the temperature should be controlled to 1350 ℃. Before the test, the electric furnace is heated to the predetermined temperature, and then the dried test materials are put into the calcined porcelain boat. The temperature of gradual test can be determined from 1000 ℃ or based on practical experience. During the whole process of the test, the porcelain boat equipped with test materials gradually pushed the furnace, insulated for 5min at the required temperature, and then gradually pulled the porcelain boat out of the furnace.
