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.

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.

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.

There are many specific contents, methods and processing technologies of water treatment, involving physics, organic chemistry and microbial solutions. In order to better remove the mechanical residue in water, one or more composition solutions, such as natural deposition, solidification deposition, filtration and ultrafiltration membrane, are usually applied according to the characteristics of solid chemicals. The practical experience has proved that the physical and chemical solution of filtration can reach the higher water body regulations after sedimentation and coagulation sedimentation, which is an economic development and effective enterprise water treatment technology. Water treatment quartz sand is a common filter material. In addition, there are also filter materials used to remove some residues in the water.
