PTFE composite filter paper is widely used in many fields such as air purification and industrial dust removal. It has a reliable filtration level of H13-U16, low wind resistance and low energy consumption, and can meet the requirements of sub-efficient, high-efficiency and ultra-high-efficiency air filtration. filter level requirements.
There are many ways to combine two filter materials together, including hot-rolled composite, mechanical composite, adhesive composite, ultrasonic composite, etc.
Considering the physical and chemical properties of wood pulp paper, the composite method of nonwoven fabric/wood pulp paper generally adopts adhesive composite, ultrasonic composite or both.
The ptfe composite filter paper product is made of polytetrafluoroethylene. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process to become a new type of filter paper. Material.
The porosity can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um. The high-efficiency filter paper has high and low temperature resistance (-200℃ -260℃), it will not age, split or discolor after long-term use and has strong weather resistance.
The ptfe composite filter paper produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. It can filter some very small particles with a diameter of 0.1um-0.3um. The level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
