It goes without saying that everyone knows how popular masks are nowadays. Today I will introduce to you a very popular mask. It is a mask made of ptfe mask film. Let us learn more about it in detail. .
The materials required to make traditional masks are generally ordinary non-woven fabrics, cotton cloth or gauze.
Current dust masks are generally made of two layers, inner and outer, with a layer of filter cloth in the middle.
The filtering of dust in the air mainly relies on the filter cloth in the middle. However, ordinary filter cloth can only intercept some dust with larger particles, and cannot have a good effect on those fine dust.
So, people continue to conduct scientific research, and finally discovered that there is a material that can effectively block those fine dust in the air, which is the environmentally friendly material PTFE mask film.
Polytetrafluoroethylene has a strong application background in traditional industrial fields and is often used as a purification material. One of the reasons is that it is washable and has low moisture absorption.
The filter layer used by the mask membrane is less than 1/6 the thickness of traditional non-woven masks, and the breathing resistance of the mask is positively correlated with its thickness.
The nanometer-scale distribution of membrane pore sizes makes a layer of physical screening and filtration a reality, greatly reducing breathing resistance.
Only 1/2 of traditional non-woven masks.
