If the test material is not sintered, it shall be replaced with a new test material, and 50 degrees shall be raised one by one according to the sintering condition until the test material is sintered. Test materials with sintering point higher than 1350 ℃ shall be tested in high temperature electric furnace with temperature higher than 1350 ℃. During the test, put the test material on the heat-resistant porcelain boat or tablet computer, and carry out the test according to the above requirements. The actual screening effect of white quartz sand filter varies with the actual filtering effect. Quartz sand filter material is now the filter material for economic development. Most sewage treatment stations are inseparable from quartz sand filtration materials and quartz sand filtration devices. At present, there are three kinds of quartz sand filtering devices, single filter, double filter and multi-media filter.

Application of silicon powder in plastic products active silicon powder is an ideal synergist for polypropylene, polyethylene, high-pressure polyethylene and other products. Silicon micropowder is used for alkane epoxy resin plastic film. Its powder equipment is loose and uniform, with good film coating performance and strong structural mechanics function. Compared with the plastic packaging film produced with PCC as filler, the infrared induction transmittance of the barrier is reduced by more than 10%, which is extremely beneficial to the application of agricultural machinery shed film. It can also be used in areas where the outer sheath of cables and wires is too long. Application of silicon powder in laminated glass and glass fiber for melting instruments and equipment due to its small particles and high purity.

When used in rubber, it can increase the volume of rubber, improve the technological performance of rubber, play a semi reinforcing or reinforcing role, and adjust the strength of rubber. Used in building materials, it has the characteristics of high temperature resistance, solvent erosion resistance, low temperature resistance, sound insulation and noise reduction, earthquake resistance, and easy production and processing. It can be used as door, ceiling, panel wall, wood floor, cable, etc. In oil soluble building coatings, heavy calcium can be used as filler, which can have a framing effect. In plastics, it can increase the volume of plastics, reduce production costs, improve the stability of plastic specifications and the strength and stiffness of plastics, improve the production characteristics of plastics, improve the temperature resistance of plastics, and improve the astigmatism of plastics.

What is the main use of quartz sand? What are its main uses and effects in industrial industry and daily life? In the eyes of ordinary people, quartz sand is only one kind of industrial mineral raw materials. In fact, quartz sand is not an organic chemical dangerous goods. It is widely used in glass, casting, porcelain and refractory materials, smelting ferrosilicon, metallurgical industrial solutions, metallurgical industry, engineering construction, chemical plants, plastics, rubber, wear-resistant materials and other industries. The key component of quartz sand is quartz, with a relative density of 2.65 grams per cubic centimeter and a hardness of 7. The crystal belongs to the 60000 crystal system, and its appearance is milky white, grayish green, grayish white, etc.

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.

In the production of refined quartz sand, generally speaking, there are three ways of iron removal: mechanical equipment wiping iron removal, magnetic separation equipment iron removal and ultrasonic wave iron removal. The iron removal by mechanical equipment wiping is mainly to remove the iron residue outside the quartz sand raw ore according to the effect of external force. There are two kinds of mechanical equipment wiping: rod mill wiping and mechanical equipment wiping. When using mechanical equipment to remove iron, some aqueous solutions are also required to cooperate with each other, and the concentration value of coal slurry is set to a certain ratio to remove iron from raw ore quartz sand. However, this kind of iron removal method is only applicable to some manufacturers with small production capacity or the situation where the quality of raw quartz sand is very good.
