Particle size and particle size analysis: particle size refers to the size of particles. Particle size analysis refers to the proportion of particles of various sizes in the number of particles in the powder sample. It is common for people to use "screen mesh number" to indicate the fineness of the powder, and D97 is used to indicate the relative particle size. However, a simple D97 does not mean the fineness characteristics of the powder, and a complete particle size layout should be used to show the fineness characteristics. In plastic products, the narrower the scope of calcium carbonate particle size analysis, the more stable the production, processing and product quality; The wider the particle size analysis is, the more difficult the production and processing are, and the product quality is unstable.

Generally speaking, there are three methods of iron removal: mechanical equipment scrubbing, magnetic separation equipment and ultrasonic wave. The iron removal by mechanical equipment scrubbing is mainly to remove the iron residue outside the raw quartz ore through the actual effect of external force. Mechanical equipment scrubbing also includes rod scrubbing and mechanical equipment scrubbing. When mechanical equipment is used for iron removal, some aqueous solutions are required to cooperate with each other, and the concentration of coal slurry is set to a certain ratio to conduct iron removal and carding of raw ore quartz sand. However, this kind of iron removal method is only applicable to some manufacturers with small output, and the quality of raw quartz sand may be very good.

Application of silicon powder in plastic products Active silicon powder is added to rubber, cis-1,4-polybutadiene rubber, etc. The powder equipment is easy to loosen, the professional skill of rubber mixing is good, and the injection and extrusion properties are good. It can also develop the vulcanization rate of vulcanizates, and improve the viscosity of plastics, especially the ultra-fine silicon powder, which replaces some white carbon black added to rubber, The development of physical property index values of finished products and the reduction of product costs have good practical effects. Silicon micropowder is used in the battery rubber shell instead of clay, active calcium carbonate and other powder equipment materials, with the charging amount up to 65% and superior professional skills.

Quartz glass is a kind of glass containing only silicon dioxide. Because of different types, processing techniques, and raw materials, they are often called silicate glass, quartz glass, fused quartz, fused quartz, and fused quartz, as well as transparent, translucent, and opaque quartz that have not been defined overseas. In China, quartz glass is commonly called quartz glass, which is classified according to the processing method, main use and appearance, such as transparent quartz glass for electric melting pipe fittings, continuous melting quartz glass, gas refining transparent quartz glass, generated quartz glass, opaque quartz glass, electronic optical quartz glass, quartz glass for semiconductor materials, and quartz glass for energy-saving lamps.

The plastic increases the plastic volume and reduces the commodity. This product improves the stability of plastic specifications and the strength and rigidity of plastic, improves the production and processing characteristics of plastic, improves the temperature resistance of plastic, improves the plastic astigmatism, and uses the high whiteness, water absorption, high impact compressive strength and other characteristics of calcium carbonate. Heavy calcium carbonate has the characteristics of corrosion resistance, low temperature resistance, sound insulation and noise reduction, and earthquake resistance, which is convenient for production and processing. Secondly, active calcium carbonate dolomite raw materials are mainly used as fillers in the fields of plastics, plastics, paper industry, architectural coatings, inks, and other fields, as well as chemical raw materials such as tooth cleaning powder, toothpaste, and skin care products. It is used for mechanical equipment generation, metallurgical industry, and laminated glass wool production to manufacture heavy calcium iron ore.

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.
