It is said that the development of the times is inseparable from the progress of science and high-tech. As an innovative pioneer in the high-tech industry, we have developed ptfe bubble point film composite materials, which provides the most powerful support for the development of various fields in our country. and protection.
Filter selection: The currently used filter pore size standard** is 0.2um. The pore size of 0.2um or smaller is based on microbial interception experimental testing, rather than based on the average particle size of microorganisms. Sterilizing filtration The effective filtration rate of the device is no less than 107 colonies per square centimeter.
Therefore, it is necessary to verify it in the actual selection and select the appropriate instrument according to the instructions.
PTFE bubble point film composite material, also known as ptfe bubble point film, is generally made of polytetrafluoroethylene (ptfe) suspended powder as raw material, which is expanded and stretched to form a microporous film.
It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore size ranges from 0.1μm to 0.5μm.
Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material.
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.
