Calcium carbonate is a kind of odorless white powder, which is widely used as an inorganic filler. As a white color paste, calcium carbonate is of high quality and low price. It has rich resources and high taste, and is widely used in building coatings, plastics, rubber and other industries. Calcium carbonate is used as electrostatic powder, which has the characteristics of high powder rate, large total paint area, no sand, no heavy metal exceeding the standard, etc. The type of calcium carbonate depends on the different production methods of calcium carbonate. Calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloidal solution calcium carbonate and crystalline calcium carbonate. According to the macro structure of calcium carbonate, the sorting methods are different, that is, the sorting of molecules and positive ions and whether there is regularity.

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.

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.

Physical mechanical equipment, such as magnetic separation equipment, selection, flotation reagents, ultrasonic separation, water cleaning, etc. In the chemical method, strong oxidants and organics are selected for leaching, and iron oxide on the surface of iron or quartz is removed according to chemical changes. After the fine white sand particles are broken through production and processing, there are still single impurities and impurities in the form of color spots on the surface of quartz sand or mixed with the internal structure of quartz sand. Such impurities include iron oxide, clay, biotite and organic chemical impurities. In order to reasonably reduce the composition of impurities in quartz sand, acid cleaning process is usually used to purify quartz sand in industrial production.

Basic filtering principle of quartz sand filter material: quartz sand filter material has filtering effect, just as water penetrates into the ground according to sand and stone, it blocks suspended solids in the water. The key is these weak suspended solids. The general quartz sand filter material is generally suitable for wastewater treatment. It has no problem after three to five years of application. It is only necessary to avoid the loss of quartz sand, and environmental pollution is not important. Due to wastewater treatment, sludge can itch or anaerobic respiration, and pollutants in wastewater are dissolved. If it is used for pure water treatment, it is mainly used for fine quartz sand filter material. Generally, after the pollutants are encapsulated by quartz sand, they can no longer have good filtering effect, and only need to be replaced.

Activity of surface treated heavy calcium: surface treated heavy calcium is also called active heavy calcium. In order to better improve its fusion with the raw materials of the base material and enhance its dispersivity, it is necessary to solve its activity. For heavy calcium manufacturing enterprises, surface treatment of calcium carbonate is the main way of commodity production and processing, which can enhance the added value and obtain faster economic benefits. However, for the active calcium carbonate and the following customers, the active calcium carbonate should be used, followed by heavy calcium, which is usually solved by physical covering or organic chemical mechanical equipment to modify materials. Its working principle and the whole process are different from the anti condensation solution of carbonization in the production process of light calcium.
