The role of medical masks in daily life
Medical masks are a kind of protective medical supplies often used in the medical industry. At the same time, medical masks are also used in other industries. In some industries containing toxic gases or steam, medical masks are also used.
Medical masks have the functions of dustproof and anti-virus, can filter substances that are toxic to the human body, and are very important to health. Woven gauze dust masks are respiratory protective equipment that only protects personnel's respiratory organs from harmful substances. It is generally composed of a mask and a filter box. The filter box is equipped with an adsorbent or a sorbent, and the adsorption effect is very good; some filter boxes are also equipped with a filter layer, which can prevent aerosols at the same time. The gas masks used in the military are mainly made of activated carbon cloth, or use water-resistant and oil-resistant fabric as the outer layer, glass fiber filter material as the inner layer, and activated carbon-impregnated polyurethane foam as the bottom layer. Provide temporary protection. There are many types of respirators, but in terms of structure and working principle, they are mainly divided into two categories: air filter masks and air supply masks.
(1) The working principle of an air filter mask, or simply a filter mask, is to make the air containing harmful substances filter and evolve through the filter material of the mask before being inhaled. The structure of a filter mask is divided into two parts, one is the main body of the mask, and the other is the filter material part, including filter cotton for dust prevention and chemical filter box for anti-virus.
(2) Air-supplied masks refer to clean air sources that are isolated from harmful substances, and are sent to people's faces through tubes and masks for breathing by means of power, such as air compressors, compressed gas cylinder devices, etc. The role of medical masks in daily life is very important.
