PTFE Nano-Pore Size Air Filter Film

Product Description

Poly Tetra fluoroethylene, short for PTFE, is a polymer prepared with polytetrafluoroethylene as a monomer. White waxy, translucent, good heat and cold resistance, can be used at -180 ~ 260ºC for a long time. This material has acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high-temperature resistance, its friction coefficient is very low.

PTFE nano-aperture air filter membrane is PTFE as raw material, using PTFE film unique node fibril, smooth surface, chemical resistance, permeability, permeability, flame retardant, high-temperature resistance, strong acid and alkali resistance, non-toxic characteristics, etc. After baking, extrusion, calendering, bidirectional stretching, and heat setting, it forms a film product consisting of millions of continuous interconnected filaments with a non-concentric cross arrangement structure.

The internal structure of PTFE nano-pore membrane prepared by bidirectional stretching process presents node-pore staggered distribution, small and uniform pore size, high porosity (> 80%), and is a kind of multi-functional high-end material. PTFE membranes are characterized by extremely high efficiency, which can be achieved from E10-U17 levels of purification efficiency. Low air resistance, its resistance is only 1/2-1/3 of the glass fiber filter material. High chemical stability, high-temperature resistance, corrosion resistance, aging resistance, very low surface energy, low adhesion to dust, easy to blow dust. Surface filtration performance can blow back dust or water washing, long service life. The filtration efficiency of PTFE microporous air filter membrane is high, up to 99.99%, close to zero emission; Low running resistance, fast filtering speed; Long service life, and reusable, thus reducing operating costs.

PTFE nano-pore size air filter membrane categories are divided into bubble film, composite material, clothing film, air filter film, and electronic film.

Product Feature

1. Surface filtration mechanism

PTFE air filter membrane has excellent surface filtration performance, the pore size of the membrane is small and uniform, and dust is not easy to penetrate the filter membrane into the base cloth when a large amount of dust is filtered, will adhere to the surface of PTFE film, forming a filter cake, after back blowing off the cake, to restore the original permeability.

2. High filtering efficiency and high QF value

The pore size of the PTFE microporous membrane can be up to 0.1μm, so PTFE material can achieve very high filtration efficiency and can meet the sub-high efficiency, high efficiency, ultra-high efficiency air filter filtration efficiency level requirements. phase compared with other high-efficiency filtration materials, PTFE microporous membrane has a higher QF value and better filtration performance.

3. Good uniformity and stable product performance

The uniformity of bidirectional stretch film is difficult to control, mainly including the permeability uniformity of transverse and longitudinal, but this has a great impact on the performance stability of the final device, so the raw material, process, and equipment will be reasonable design and strict control. Through the uniformity analysis of product resistance, the CV value of our membrane product can reach 7%.

4. High porosity, high permeability, and high interception efficiency can be achieved simultaneously

Using the high temperature stretching process, the knot-fiber structure is regular, has high porosity, uniform pore size distribution, and the average pore size in the range of 0.1-5^m adjustable, on the one hand, the high density of fiber accumulation ensures the filtering accuracy of fine and small dust, On the other hand, high porosity and good pore size uniformity make the air permeability of the film is also excellent. The balance of high permeability and high interception efficiency makes the product very suitable for the interception and collection of fine dust. After testing the resistance and filtration efficiency, the QF value of our membrane products can reach more than 29 (0.1-02 particle size segment).

5. Good membrane strength and long service life

Generally, the relative density of the standard is small (SSGW2.162), and the molecular weight is high (Mn & GT; 7 million)) and PTFE powder with narrow molecular weight distribution, the strength of the raw material is high, and the same permeability and density of the film are higher so that the performance is more reliable and longer service life.
