In today’s society, environmental pollution is becoming increasingly serious, and the first thing to be affected is air pollution. Therefore, when traveling in hazy weather, most people wear masks to block harmful gases in the air.
But, can the masks we usually wear really effectively block those harmful gases in the air? Today we will learn about traditional masks and PTFE masks.
The main component of polytetrafluoroethylene film masks is polytetrafluoroethylene mask film, referred to as ptfe film.
Masks made of this material are very different from ordinary masks, and the contrast between the two is very obvious.
Comparison 1: The barrier efficiency of polytetrafluoroethylene mask membrane is higher.
This is mainly due to the fact that it uses materials with smaller fiber diameters compared to traditional masks.
Generally speaking, the fiber diameter of the ordinary non-woven materials used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE film material is between 100 and 200 nanometers, which is much smaller than the above diameters. , so it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.
Comparison 2: Masks made of polytetrafluoroethylene mask film have a longer service life.
The reason for this is that it uses physical principles to block pollutants in the air, so it is more durable.
The ordinary non-woven fabric used in our traditional masks relies on static electricity to absorb particles in the air due to its large fiber diameter. However, static electricity will lose its effectiveness within a short period of time, so it can only be used once.
Comparison 3: A mask made of polytetrafluoroethylene mask film makes breathing easier and freer when worn.
PTFE membrane is a flexible and elastic material with high porosity and very uniform pore size, so it has very good breathability.
The breathability of the materials used in traditional masks is far inferior. If worn for a long time, it will feel damp and hot, which can cause some abdominal diseases and is not good for physical and mental health.
