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.

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.

Fine quartz powder is used as the raw material of paint, which can not only increase the filling capacity, thicken and perish in the paint, but also has the coloring characteristics of building paint and paint, moisture-proof, corrosion resistance, bacteria resistance, anti caking, avoiding flowing column, compressibility, ultraviolet radiation, anti-aging, strength film, heat resistance, high score, scrub resistance, and the smoothness of the surface of the insulation layer resistant to electricity. Ultra fine quartz powder has no environmental pollution caused by organic compounds and low metal composition It can improve the UV resistance of the coating film and has good thermal insulation It is necessary to improve the reliability of paint, building paint, storage and reduce costs.

If the crushed debris is not washed away but deposited on the surface of the filter layer, the water yield will increase. Friction resistance, reduce filtration cycle time, and reduce water flow. Therefore, various mechanical properties of filter materials should be manipulated. When it is very large, the fine suspended solids will be based on the filter layer. It is not easy to loosen the filter layer during backwashing. The backwashing is not complete, and it is very easy to harden the bottom. The running water is uneven, resulting in the reduction of water bodies and the rapid invalidation of the filtering equipment; If the particle size is too small, the flow friction resistance of water will be very large, and the filter layer is easily blocked by floating solids in the whole process of filtration, thus increasing water loss too quickly.

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.

Adding colorful quartz sand to the transparent epoxy resin paint can obtain the actual effect of the floor similar to marble. The difference is in color. The color sand epoxy resin floor paint has a large number of choices and matching. The color sand floor is not only more beautiful in appearance design, but also more powerful in physical and chemical properties, which is also because the abrasion resistance and compression resistance of quartz and strong organic chemical resistance improve the compressive strength of the floor. According to the application of color sand flooring, the natural environment of the flooring can obtain higher toughness and service life, so it is suitable for the application in places with high aesthetic requirements and high compressive strength, such as stadiums, hospitals and outpatient clinics.
