Using the special node fibrillation of PTFE film, smooth surface, chemical resistance, air permeability and water impermeability, large air permeability, and resistance to It has the characteristics of combustion, temperature resistance, strong acid and alkali resistance, etc., and can be used for atmospheric dust removal, air purification, etc.
PTFE film is based on nanofibers prepared by high-tech electrospinning technology and constructed through a composite process The three-dimensional nanoporous membrane has a filtration accuracy of 0.3 microns, and the filtration efficiency for haze (PM2.5 particle size is 2.5 microns), dust, and pollen is higher than 99%, and it also has other strong functions. Nanofibers are used to build a three-dimensional structure, which has a large specific surface area, that is, a large surface area/volume ratio. It has many micropores on the formed mesh, has a high porosity, greatly reduces air resistance, and at the same time is resistant to dust particles. The adsorption capacity has also been greatly improved.
Using these structural characteristics of polytetrafluoroethylene film for submicron air purification and fine particle air purification, its filtration The efficiency is greatly improved compared to conventional air filtration materials. For example, compared with the filtration efficiency of nano air filtration membranes and conventional vinylon fiber filter felts of the same weight, the former is more than 5 times that of the latter.
The polytetrafluoroethylene film produced has strong hydrophobicity, chemical resistance, hydrophobicity and low wind resistance. And it can achieve high dust removal efficiency. For some extremely fine particles with a diameter of 0.1um-0.3um, the filtration level can reach H13-U16. In addition, the biaxially stretched film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company and complies with current environmental protection standards.
