The filter elements in the chemical industry are currently mainly occupied by large manufacturers, with hundreds of thousands of models involved.
In terms of material selection, it is generally determined based on the use environment of the filter element. For example, it needs to be resistant to high pressure, acid and alkali, etc.
In terms of technology, currently, no one can say for certain based on the combination of one's own product design and one's own equipment. But it must meet the environmental requirements of the filter element. High-strength built-in steel plate round hole punching support, and end caps are mostly made of engineering plastics. The filter material generally chooses fiberglass or stainless steel high-precision woven cloth. As for domestic industrial filter elements, the outer protection net generally chooses round-hole punched steel mesh or diamond-shaped hole stretched steel mesh. Common filter materials are glass fiber, chemical fiber, and stainless steel. End caps are mostly made of steel plates or aluminum, and some are made of engineering plastics.
Industrial filter elements range from 0.01 to 500um in terms of filtration accuracy.
Industrial filter elements come in many types of filter materials. Common ones include fiberglass, chemical fiber, polyester, stainless steel (various models such as 304, 304l, etc.), nickel microporous, oil-absorbing felt, water-repellent mesh, etc. Generally, industrial filter elements are made of a variety of materials to meet the needs of the use environment.
Support material, mainly involved. Stainless steel (various models such as 304, 304l, etc.), cold-rolled steel plates, engineering plastics, etc.
The material of the end cap is almost the same as the support material
The design of the industrial filter element end cover needs to be completely matched with the use environment.
Final summary: Industrial filter elements are a high-end filtration industry and must have their own R&D department with advanced production machines and testing equipment.
