Anionic polyacrylamide is a water-soluble linear polymer with high degree of polymerization. It has flocculation, thickening, shear and resistance reduction properties. Dispersion and other valuable properties. Anionic polyacrylamide although the water surface tension reduction is very small, but the molecule has active groups, adsorbed on the interface, can change the interface state. Its cool amine group (CONH2) and many substances affinity, adsorption to form hydrogen bonds, which can make it in the adsorption of particles of the bridge, so that several or even dozens of particles connected together, can promote colloidal particles gathered into large flocculent, accelerate the settlement of particles in the suspension, accelerate solution clarification, promote filtration and other effects.

Activated alumina has the characteristics of large adsorption capacity, large specific surface area, high strength and good thermal stability. It can be widely used as adsorbent, desiccant and catalyst carrier in chemical, petrochemical and fertilizer industries.
Our companys main product is fiber ball filter media. Filter balls is made of polyester or polyethylene, eco-friendly recyclable material.Now it is a alternative of filter sand with the advantage of better filtering effect, easy to use, light to handle, no leak of sand in the pool, less backwash, energy saving. Compared with the traditional rigid filter, the fiber ball filter has the advantages of good elasticity, non floating, long working cycle and small head loss. In the process of filtration, the gap of filter layer along the flow direction becomes smaller and smaller, which is consistent with the pore distribution structure of ideal filter material.
Filter balls is optimal filter media for swimming pool water treatment. Filter balls fits all existing sand/glass filters. Lvyuan Filter balls is made of polyester fiber, eco-friendly recyclable material. It is a alternative filter sand with the advantage of better filtering effect easy to use, light to handle, no leak of sand in the pool, less backwash, energy saving.
Manufacturers selling white corundum abrasive powder, white corundum, white corundum is high-quality aluminum oxide powder as raw material, the crystal in a fused, slightly higher than the corundum hardness, toughness is a bit low, high purity, good self sharpening, strong grinding ability, low calorific value, high efficiency, high temperature, acid and alkali corrosion thermal stability is good. It is used to make grinding tools for grinding high speed steel, high carbon steel and so on. It is widely used in consolidation grinding tools, coated abrasives, polishing and precision casting industries. White corundum abrasives are suitable for surface treatment and beautification of various high-end products, crafts or hardware products. After blasting, the surface is clean without any impurities. Because white corundum is made by electrofusion and crystallization, its hardness is slightly higher than that of brown corundum, its toughness is slightly lower, its purity is high, acid and alkali resistance is corroded, and high temperature and thermal stability are good. It is a high-grade refractory material. Fine white corundum can be used for polishing and grinding, and can also be used as a kind of additive for various products. The granularity of the white corundum products produced by Ningxia Tengyuan environmental protection material Co., Ltd. is manufactured according to international standards and national standards, and can be processed according to the requirements of the user. The general particle size is F4~F220, and its chemical composition varies depending on the size of the particle. The prominent feature is small impact resistance to crystal size. If the grinding machine is broken, the particles are mostly spherical particles, the surface is dry and easy to bond.
