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.

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.

In the case of pure water purification treatment, the general application time period will produce some relatively. In the case of pure water purification, everyone's water resources are relatively clean, generally all surface water, precipitation and drinking water. This water quality is relatively clean, so there are relatively few residues and organic compounds, so the time period used is relatively long, and the general replacement cycle is once in 1-2 years. It is the quartz sand in the reclaimed water treatment. The goal of reclaimed water treatment is to save water and use it repeatedly. Then the quality of reclaimed water is relatively poor. Generally, the replacement cycle is about 12 months.

Snow white sand is a colorless transparent quartz, which is called amethyst in Greek, meaning white ice. They firmly believe that quartz is durable ice. Snow white sand is a kind of preloaded clastic rock. It originates from various skarns and sedimentary rocks. There are very few heavy minerals, and the associated minerals are marble, biotite and clay minerals. Quartzite can be divided into two types: accumulation causes and metamorphic causes. The former one has no obvious boundary between the crushed slag particles and the binder, while the latter one refers to the quartzite iron ore with deep metamorphic level and pure quality. Vein quartz is produced by hydrothermal effect, almost all of which are composed of quartz, with high-density small structure.
