There are three key types of calcium carbonate: high quality calcium carbonate and light quality calcium carbonate. Heavy calcium carbonate is produced by crushing natural dolomite, limestone, limestone, pearl shell, etc. immediately with equipment. Light calcium, also known as sedimentary calcium carbonate, is produced by calcining raw materials such as dolomite to produce lime powder, adding water to digest and absorb lime powder to form mature lime, and then filling carbon dioxide to carbonize and deposit, which is dried, dried and crushed. Or, first, dilute hydrochloric acid and calcium chloride are used to carry out the double decomposition reaction to form calcium carbonate deposits, and then they are prepared by dehydration, drying and crushing. Because the production method is different, light calcium has a large deposition volume and looks light. In fact, the relative density of the two is not very different.

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.

The magnetic separation equipment removes iron according to the chemical properties of iron. The magnetic separation equipment has two methods, dry separation and wet separation, each of which has its own advantages. When it is used, the composition of raw quartz sand should be measured as far as possible. If the raw quartz sand contains hematite, limonite, biotite and other weak magnetic residues with intergrowth particles in it, the wet separation is the only way, However, the disadvantages of wet separation are large power consumption, easily damaged materials, large water demand for production, and high operation and maintenance costs. If the above residues are not available, dry separation can be used. Compared with wet separation, the cost and maintenance are extremely low.

Silicon micro powder is not as hard to move as industrial equipment, because it is a agglomerate particle. In the process of transportation, measures such as packaging, safety protection and fixation should be taken. Otherwise, once leakage and other problems occur in the whole process of transportation, it will cause greater damage to rights and interests. Now let's talk about the common problems when transporting this product. Understand the physical and organic chemical characteristics of the goods before transportation. In summer, the car shall be equipped with awning poles and awnings. Ventilation and shading shall be provided, especially to avoid sunlight. When loading, unloading and handling, handle with care. Do not drop, drag, press or rub. Do not damage the packaging containers. Pay attention to ensure that the other party is in place.

The magnetic separation equipment removes iron through the chemical properties of iron. The magnetic separation equipment has two methods, dry separation and wet separation, each of which has its own advantages. In application, the composition of raw ore quartz sand should be measured first as far as possible. If the raw ore quartz sand contains weak magnetic residues such as hematite, limonite and biotite with intergrowth particles in it, only wet separation can be used, However, the disadvantages of wet separation are large power consumption, simple material damage, large water demand for production, and high work and maintenance costs. If the above residues are not available, dry separation can be used. Compared with wet separation, it has very low cost and maintenance.

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.
