A detailed description
The titanium filter element is a new type of high-efficiency porous filter material made from titanium metal powder as raw material and processed through powder classification, molding, sintering, mechanical welding and other processes. Because of its pores and filtration accuracy, it can be carried out in a fairly wide range. Adjustment, is widely used in fields such as self-lubrication, filtration, separation, catalysis, flame extinguishing, heat exchange, hot electron generation and gas distribution.
Main uses: used for filtration of gases and liquids and gas distribution. Filtration precision: 0.22～50μm Diameter: 30～80mm Length: 100～1000mm (special specifications can be customized)
Filtration principle: The titanium filter element is a titanium metal porous filter material made by powder metallurgy. Its internal pores are curved and crisscrossed, with uniform pore size distribution. The filtration mechanism is a typical deep filtration.
Performance: This product has excellent properties such as corrosion resistance, high temperature resistance, high strength, easy to ensure filtration accuracy, and easy regeneration; the titanium filter element is made of titanium powder that is formed and sintered at high temperature, so the surface particles are not easy to fall off; used in the air The temperature can reach 500~600℃; it is suitable for filtration of various corrosive media, such as: filtration of hydrochloric acid, sulfuric acid, hydroxide, sea water, aqua regia and chloride solutions such as iron, copper, sodium and so on. It has excellent mechanical properties and can be processed by cutting, welding and other machining. It has high pressure resistance and internal pressure destruction strength of up to more than 2MPa. Its filtration accuracy is easy to ensure, and the pore diameter will not deform even when working under high temperature and high pressure. Its porosity can reach 35-45%, the pore size distribution is uniform, the dirt holding capacity is large, and the regeneration method is simple, and it can be reused after regeneration.
