Quartz sand filter material can often distinguish ordinary quartz sand from refined quartz sand, first because its appearance is very different. The second is the manufacturing process. Generally, quartz sand for sewage treatment only needs simple processing processes such as crushing and drying. The raw quartz sand used for general quartz sand is also different from refined quartz sand. The surface layer is generally yellow skinned quartz sand. The iron ore without impurities on the surface layer is immediately produced and processed into refined quartz sand, but the quality of iron ore is poor. After acid pickling and passivation of refined quartz sand, its pale yellow surface is melted and cleaned after acid pickling and passivation, and its appearance is transparent, beautiful and generous.

Characteristics of light calcium carbonate Calcium carbonate is non irritating, odorless, white, dry, carboxyl free, soft powder, and its strength is Mocha No. 3. Light calcium carbonate is a chemical production of calcium carbonate, with an average particle size of 0-6um and a glossiness of more than 95%, which is usually used as an electrostatic powder of calcium carbonate. Heavy calcium carbonate is made of natural dolomite, limestone and other raw materials by mechanical equipment. Because of the variety of equipment, its application in electrostatic powder is limited. It plays a framing role in the electrostatic powder. Their addition can improve the thickness of the coating, corrosion resistance and durability of its coating.

Organic Chemistry Reliability. When the filter material is soaked in the water to be treated and filtered, its physical properties should be kept for a long time to avoid the chemical change between the filter material and the filter material, which will lead to the deterioration of the water body. It cannot include chemicals that are harmful to health and production. For example, water treated quartz sand can be used in intermediate, acid-base and slightly alkaline water, but discomfort is used to use water treated quartz sand as a filter for water that needs to be softened, because SI02 in quartz sand will melt and endanger its quality. Mechanical properties, impact toughness. The filter material shall have sufficient impact toughness to reduce the mutual friction of particles during the actual operation period of backwashing.

Porcelain filter material made of bauxite has been used in engineering projects. Because the filter material has many microporous plates, large total area, high porosity and strong absorption function, it can replace quartz sand or anthracite filter material layer. Wooden filter materials, such as golden pomelo shell, are increasingly used because of their uniform particle size, light volume, high compressive strength, damage resistance and remarkable de oiling effect. Filter materials such as water treatment quartz sand and anthracite shall meet the following application standards: the physical properties are stable and not easy to harm the quality of wastewater; With good impact toughness, it is not easy to break in the whole process of application; Medium level granularity.

Some technical indicators of calcium carbonate include mesh size, whiteness and calcium carbonate content. Screen mesh number: the mesh number refers to the total number of holes on the stainless steel screen in the total area. The larger the mesh number, the smaller the particle size, and the required processing technology will be more complicated. Generally, the filler with large mesh size needs surface treatment to enhance its dispersion. Whiteness: Because pure calcium carbonate is milky white, the higher the content of calcium carbonate, the whiter the products will be, and the less miscellaneous. Ferrite and silicon will make the products yellow and dark. Generally speaking, when the whiteness is higher than 90%, calcium carbonate can be used as an opalescent dye for plastics, but many manufacturers are not satisfied with the 90% specification.

Select appropriate packaging containers and transport goods properly. Before transportation, dangerous goods shall be packaged according to their characteristics, transportation routes, road conditions along the road and other safety methods. The package must be firm and tight, and clear, standard and easy to identify marks shall be made on the package. During transportation, the driver shall drive stably and safely. The transport driver shall be highly skilled, and shall not drive fast, drink, smoke or drive dangerously. When driving safely, try to avoid using the emergency brake pedal to maintain the stability of the goods. Check the silicon powder frequently during driving to see if there is any leakage. Because the car shakes and vibrates during driving, it is usually easy to cause package damage and leakage.
