“Wine has the fragrance of old age, haze is the richness of imperial capital.” When I saw such a joke again, I suddenly realized that the haze season has arrived for another year.
We are in the season of wearing masks again, so are your anti-smog masks ready? Today we will take a look at masks made of polytetrafluoroethylene mask film.
The “PTFE film”, known as the king of plastics, can withstand high and low temperatures, chemicals, radiation penetration, non-stick surface, atmospheric aging resistance and other comprehensive protection, but the first and second generation PTFE circulating on the market The film has the following problems: it cannot be washed with detergent, it is not breathable (second generation), and it is not resistant to oil and alcohol.
The above shortcomings have been overcome in the third generation, and the durability has been improved to more than 10 years. The material has even entered the medical field and has successfully made artificial organs, attracting much attention in the industry.
The polytetrafluoroethylene mask membrane has high-density micropores, which is refreshing and breathable. The film has excellent properties of micropores, hydrophobicity and non-moisture absorption. Water vapor is not easy to accumulate, and it can quickly wick away moisture, keeping it fresh and breathable for a long time.
Due to the different materials of masks, the effects are also different. Non-woven and cotton ordinary fabrics will attenuate with filtration time, while masks made of ptfe film are long-lasting and stable, can be self-cleaned, have the same resistance, and filter It is also more efficient than ordinary masks.
