What is the main structure of PTFE film?
The main structure of polytetrafluoroethylene film: 1. The surface morphology of ptfe film is a spider web-like microporous structure. Pores are formed between the microfibers, and the arrangement direction of …
What principle is used to make ptfe mask film? What are the characteristics?
PTFE mask membrane refers to a new type of mask that uses a single layer of nano-PTFE film material as the filter material. The principle is to use the latest film material with a fiber diameter between 100 and…
Why do all current vacuum cleaners use PTFE air filter membranes?
PTFE air filter membrane has a node-fine fiber structure, forming hundreds of millions of micropores per unit area, which can effectively intercept dust in the air. It is very suitable for air purification fiel…
Why is ptfe mask film better than traditional masks?
The protective function of film masks is very strong, far better than ordinary masks. Answer this question from two perspectives. First of all, membrane masks have better filtration effect. This is mainly becau…
What is the filtration effect of ptfe mask membrane on PM2.5?
PTFE mask membrane is made of suspended polytetrafluoroethylene resin by molding, sintering, cooling into a blank, and then turning and calendering. The membrane has a node-fine fiber structure with small pore …
What principle is used to make ptfe mask film?
Thin film masks refer to new masks that use a single-layer nano-PTFE mask membrane as the filter material. The principle is to use the latest film material with a fiber diameter between 100 and 200 nanometers. …
What are the applications of ptfe waterproof and breathable membrane in medical medicine?
PTFE waterproof breathable membrane is purely inert, has very strong biological adaptability, will not cause rejection by the body, has no physiological side effects on the human body, can be sterilized by any …

What are the applications of the anti-stick properties of PTFE microporous membranes?
PTFE material has the smallest surface tension among solid materials and does not adhere to any substance. It also has excellent high and low temperature resistance, making it widely used in anti-stick applicat…
Can swimming pool filter material be used in baby swimming pools?
I believe that for baby swimming pool operators, the use of baby swimming pool filters is no stranger. To put it simply, the filter element can filter impurities in the water and reduce operating costs. Many br…
Why is PTFE microporous membrane uniform and stable?
In actual production, due to problems such as uneven density distribution of the raw resin, uneven mixing and kneading, and uneven tension during stretching, polytetrafluoroethylene microporous membranes often …
