Do you know the material of ptfe high-efficiency filter paper, and do you know its specific functions and advantages? Today I will take you to learn about this material.
In order to determine the level of a Class A area, the sampling volume of each sampling point shall not be less than 1m3.
The level of air dust particles in Class A areas is ISO4.8, with dust particles ≥0.5μm as the limit standard.
The level of air dust particles in the B-level area (static) is ISO5, including dust particles of two sizes in the table.
For Class C zones (static and dynamic), the levels of air dust particles are ISO7 and ISO8 respectively.
PTFE high-efficiency filter paper is suitable for various clean rooms from Class 1 to Class 100,000. It adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
The ptfe high-efficiency filter paper produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can obtain 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.
