As we all know, ptfe nanofilm has excellent chemical corrosion resistance, high and low temperature resistance, aging resistance, low friction, dielectric properties, non-stickiness, and physiological inertness, making it widely used in chemical industry, machinery, electrical, construction, and medical It has become an indispensable special material in many fields. It can create new processes and technical equipment instead of traditional materials in the past, which can not only improve work efficiency but also extend service life. Its importance has attracted the attention of the world.
Paper mill flushing wastewater contains a large number of pollutants. PTFE membrane can replace absorption and electrochemical methods to remove dark lignin and chlorinated lignin produced from the wood pulp bleaching process, because many organic matter in the pollutants are Being negatively charged, they are easily intercepted by the positively charged nanofiltration membrane and do not cause major pollution to the membrane.
PTFE nanomembrane uses polytetrafluoroethylene as the main raw material and is made by wet molding process. It has the characteristics of uniform fiber distribution, large dust holding capacity, low resistance and high strength. It is an ideal air filtration material.
The technical indicators of filter paper can be mainly divided into two aspects. One is the filtration characteristics of the filter paper, and the other is the physical properties.
Filtration characteristics include air permeability, air resistance, maximum pore size, and average pore size.
The ptfe nanofilm produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of the ptfe film; it is imported from the United States It has advanced production and testing instruments to test the quality of PTFE film, and has also passed international SGS testing and certification, as well as ISI testing and certification.
