Generally speaking, the conventional production method of polytetrafluoroethylene microporous membrane is: mix polytetrafluoroethylene dispersion resin and liquid additives, make the mixture into a thin sheet by calendering, and then use a machine to biaxially stretch the sheet Thus produced.
Micropore filtration is a screening process and is a precision filtration.
Micropore precision filtration refers to the filtration technology that filters out particles from 0.1μm to 10μm. Generally speaking, the filtration mechanism is divided into two types: surface type and deep type.
Micropore filtration is a screening process and is a precision filtration.
The filtration mechanism of the polytetrafluoroethylene microporous membrane manufactured by advanced technology is surface filtration.
Since the filter pore size is fixed, the accuracy and reliability of filtration can be ensured.
Depth filtration is divided into non-fixed irregular pores and fixed irregular pores. The former, such as chemical fiber wound filter elements, is generally only used as a relatively rough pre-filtration.
PTFE microporous membrane is an excellent polymer material. This material is resistant to high temperatures, corrosion resistance, excellent dielectric properties, stable chemical properties and has good mechanical properties. Therefore, this material is widely used. In all aspects of engineering, military, and life.
However, polytetrafluoroethylene polymer is non-polar and its surface free energy is very low, which makes its surface wetting and hydrophilic properties very poor, which affects its wide application in actual production.
We are a manufacturer specializing in the production of polytetrafluoroethylene membrane materials. In the field of industrial sewage treatment, we have the characteristics of “uniform and stable, high efficiency and low resistance, long life, customizable, easy cleaning and maintenance”, etc., and are accepted by the majority of enterprises and favorite.
