PTFE bubble point membrane composite material is a very important component in filters. Its importance is self-evident, especially now that many industries need to use this high-tech material.
The bubble point test can only be used on filters of certain specifications.
The larger the filter surface area, the higher the impact of diffusive flow through the membrane on the test.
If there are a large number of large-pore membrane holes in a large area, the diffusion flow generated by the air flow will cover up the real bubble point, that is, the filter area will affect the observation of the bubble point to a certain extent. , because the larger the filter, the more air is allowed to pass per unit time.
PTFE bubble point membrane composite material has a microporous structure with staggered fibers, with a porosity of up to 80%~90%. After high-temperature heat setting treatment, the microporous structure is stable and can effectively intercept dust particles, and its pore size is Small and uniform, surface filtration mechanism, easy dust removal, strong hydrophobicity, low surface energy, good non-adhesive ability, effectively removes dust accumulated on the surface.
The ptfe bubble point film composite material produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely small particles with a diameter of 0.1um-0.3um For particles, the filtration 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.
