Basic filtering principle of quartz sand filter material: quartz sand filter material has filtering effect, just as water penetrates into the ground according to sand and stone, it blocks suspended solids in the water. The key is these weak suspended solids. The general quartz sand filter material is generally suitable for wastewater treatment. It has no problem after three to five years of application. It is only necessary to avoid the loss of quartz sand, and environmental pollution is not important. Due to wastewater treatment, sludge can itch or anaerobic respiration, and pollutants in wastewater are dissolved. If it is used for pure water treatment, it is mainly used for fine quartz sand filter material. Generally, after the pollutants are encapsulated by quartz sand, they can no longer have good filtering effect, and only need to be replaced.

Silicon micropowder is very common. The raw iron ore is obtained by crushing, water cleaning, scrubbing, extremely fine, and grading. The use of silicon micropowder is very common. Its sphericity is improved, its touch is fine, its loose adhesion is good, and its oil absorption rate is low, making it widely used in many fields, such as building coatings, electronic devices, and chemical plants, In the production and processing of silica fume, we need to pay attention to that the production and processing methods are different, the prices are different, and the regions used are also different.

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.

Particle size and particle size analysis: particle size refers to the size of particles. Particle size analysis refers to the proportion of particles of various sizes in the number of particles in the powder sample. It is common for people to use "screen mesh number" to indicate the fineness of the powder, and D97 is used to indicate the relative particle size. However, a simple D97 does not mean the fineness characteristics of the powder, and a complete particle size layout should be used to show the fineness characteristics. In plastic products, the narrower the scope of calcium carbonate particle size analysis, the more stable the production, processing and product quality; The wider the particle size analysis is, the more difficult the production and processing are, and the product quality is unstable.

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.
