Use of Guangxi Snow White Sand
Heavy calcium carbonate, commonly known as heavy calcium carbonate, is an equipment that uses fine dolomite as raw material to produce milky white powder. Its main component is CaCO3, which is insoluble in water and ethyl acetate. It has the characteristics of high gloss, good purity, mild color and stable composition. It is a major inorganic filler used in industrial production. Heavy calcium is usually used as filler, and it is also widely used in daily chemical manufacturing industries such as synthetic floor tiles, rubber, plastics, paper industry, building coatings, paints, printing inks, cables, engineering construction appliances, food, pharmaceuticals, textiles, refined feed, whitening toothpaste, etc. As filler, it can improve the volume of commodities and reduce product costs.

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.

The specific surface area of the powder sample is the sum of the areas of all particles in the sample of enterprise quality. Generally speaking, the finer the fineness, the larger the specific surface area. However, the composition of coarse powder and stone powder should also be considered. If the composition of stone powder is high, but its D97 standard value is relatively large, the condition of large fineness and large specific surface area will occur. At the same time, when judging the specific surface area, the surface appearance of particles and whether particles are solid should also be considered. If there are many holes or dents on the surface of particles, the measured specific surface area is also high. Generally, the larger the specific surface area, the higher the smoothness of the product, but its dispersion is also difficult.

Calcium carbonate is widely used, and most plastics can be used. In addition, calcium carbonate is effective in improving some properties of plastic products to expand their use standards. In plastic production and processing, they can reduce the shrinkage rate of epoxy resin, improve rheological personal behavior, and manipulate viscosity. It can also have the following functions: improve the reliability of the overall dimensions of plastic products; Improve the strength and rigidity of plastic products; Improve the processing properties of plastics; Improve the temperature resistance of plastic products; Improve the astigmatism of plastics; It can make the product have certain performance; Reduce the cost of plastic products.
