We all know that when the air quality is not very good, we will choose to wear masks when traveling, in order to prevent harmful gases in the air from being inhaled into the lungs, thereby ensuring our health.
So, can the masks we usually wear really block those harmful gases? We all know that the materials required to make traditional masks are generally ordinary non-woven fabrics, cotton 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 it 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.
Scientific research has found that as long as the PTFE mask film is added to the mask, it can effectively block small particles in the air and even some bacteria that are invisible to the human eye.
PTFE mask film, also known as polytetrafluoroethylene film, has a three-dimensional mesh structure, no through holes, and a high porosity, with the opening rate generally between 80% and 95%.
Furthermore, the filtration principle of this membrane is surface filtration, with low filtration resistance, which can block harmful gases in the air from the outside and ensure that they are not inhaled by the human body.
Controlling the pore size of this membrane to between 0.2 and 3μm can effectively trap fine dust with extremely small diameters.
These advantages are unmatched by ordinary masks.
Finally, masks made of PTFE mask film are also very comfortable to wear. Traditional masks will make people feel hot and humid after being worn for a long time, because the air inhaled when wearing such masks is mixed together. , that is to say, what we inhale is the gas we just exhaled, so wearing this type of mask for a long time is not good for our physical and mental health.
Wearing a ptfe mask will not cause stuffiness! This is due to the high porosity of the membrane, so the ventilation rate will be high.
