u003cbru003e u003cbru003eSeveral classifications of sintered filter elements u003cbru003e u003cbru003e u003cbru003e u003cbru003e Sintered filter elements can be divided into two categories according to their materials; metal sintered filter elements and non-metallic sintered filter elements. Each material has its own characteristics in different fields and scopes; u003cbru003e Metal sintered filter element includes; stainless steel sintered filter element, copper powder sintered filter element, titanium rod filter element, etc. u003cbru003eStainless steel sintered filter element; stainless steel sintered filter element is a filter element made of stainless steel powder 304/304L/316/316L as raw materials, formed by molds, and fired with high-temperature micropores. The filtration accuracy can reach up to 5um, and the permeability is good. High mechanical strength, suitable for working conditions with higher temperature and corrosive environment. It is widely used in medicine, water treatment, food, biology, petroleum, chemical industry, metallurgical industry and gas purification, dustproof and dustproof. u003cbru003e Performance index accuracy range 5-100um; temperature resistance 400℃; easy to clean, reproducible, high strength, machinable, weldable, uniform pores, can be used for material distribution, and can be used normally and stably in various acid and alkali environments . Due to the advantages of powder molding, the shape and size can be customized according to requirements. u003cbru003e Copper powder sintered filter element; Copper powder sintered filter element is made of selected spherical tin bronze (tin-zinc-copper) powder, put into a processed mold, and formed by high-temperature firing. The particle size of copper powder is between 20-300 mesh, and the pore size of the copper filter element formed by copper powder of different diameters is different, and the corresponding precision is 3-100 microns. The larger the mesh, the smaller the precision. Also because of the mold forming, the size and shape can be customized according to the requirements of different manufacturers. u003cbru003e The performance has various porosity (28%-50%), pore size (4u-160u) and filtration accuracy (0.2um-100um), crisscross channels, high temperature resistance, and resistance to rapid cold and heat. Corrosion resistance. Suitable for a variety of corrosive media such as acids and alkalis u003cbru003e Titanium rod filter element; Titanium rod filter element is a kind of industrial high-purity titanium powder (99.6%, 0.4% titanium alloy nitrogen, hydrogen, iron, manganese, etc.) as raw materials, after sieving, cold isostatic pressing , Porous titanium filter element sintered at high temperature and high vacuum. u003cbru003e Performance has excellent performance such as corrosion resistance, high temperature resistance, high strength, easy filtration accuracy, easy regeneration, etc.; titanium filter element is formed by forming titanium powder and sintered at high temperature, so the surface particles are not easy to fall off; use in air The temperature can reach 500~600℃; suitable for filtering various corrosive media u003cbru003e Non-metallic sintered filter elements include; PE sintered filter element, PTFE sintered filter element, activated carbon sintered filter element, etc. u003cbru003e PE sintered filter element; PE sintered filter element uses UHMW-PE ultra-high molecular weight polyethylene powder as the raw material to sinter the filter medium through a set process. PE filter media is the core element of microporous filters used in chemical, pharmaceutical and environmental protection industries. u003cbru003e Performance Uniform pore size distribution, strong acid and alkali resistance, high temperature resistance, good mechanical properties, and strong resistance to organic solvents. The production of large-scale water treatment equipment can adopt automatic or manual recoil deslagging method, solid particles can be recovered by dry slagging, without frequent replacement of filter elements, automatic operation, low filtration cost and other advantages, which are well received by users. u003cbru003e PTFE sintered filter element; it is made of pure polytetrafluoroethylene raw material and sintered under high temperature and high pressure, so the filter element has strong acid and alkali resistance, strong alkali resistance, high strength and toughness of the filter element, and the filter element It can withstand high temperatures up to 200°C and is known as the 'King of Filter Elements'. u003cbru003e Performance Super large flow rate and high porosity (60%) ensure greater fluid flow per unit area; smooth and smooth outer surface, impurities are not easy to stick, easy to backwash thoroughly; strong anti-fouling ability, small size, large filtration accuracy Makes impurities not stay in the filter element, and can press the sludge to 70% of the water content; Excellent cost performance The filter element has excellent comprehensive performance and low price, suitable for water treatment, environmentally friendly sewage treatment, reclaimed water reuse, and filtration of chemical products Working conditions with high flow rate; u003cbru003e Sintered activated carbon filter element; is a filter element made by mixing activated carbon powder material and polymer hot-melt pore-forming material, pouring into a special mold, and sintering at a high temperature of 200-300℃. It integrates adsorption, filtration, interception, and catalysis. It can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the effects of decolorization and removal of peculiar smell. u003cbru003e The performance pore size can be adjusted arbitrarily, the smallest can reach 0.2 μm, which is better than the large flux hollow ultrafiltration membrane on the market; the black water flowing out is less than that of granular activated carbon. After the black powder in the carbon rod is washed out for the first time, There will be no black water in the future, nor will the desorption after adsorption caused by the washing of water flow like granular activated carbon, resulting in secondary pollution; using activated carbon powder below 80 mesh processing, u003cbru003e For more information, please consult us u003eu003eu003e
