The important role of disposable masks in daily use
Disposable masks are a kind of protective medical products that are often used in the medical industry. At the same time, disposable masks are also used in other industries, such as those that operate in hazardous gas or steam environments. One of the products of the mask, there is a disposable mask.
Disposable masks are dust-proof and anti-toxic, and can filter substances that are toxic to the human body, which is very important for health. Weaving gauze dust masks are only protective devices for respiratory organs that protect people's respiratory organs from harmful substances. It is generally composed of a mask and a filter cartridge. The filter cartridge contains an adsorbent or a sorbent, and the adsorption effect is very good; some of the filter cartridges are also equipped with a filter layer to prevent aerosol at the same time. The anti-virus mask used in the military is mainly made of activated carbon cloth, or the outer layer is made of water-resistant and oil-resistant fabric, the inner layer of glass fiber filter material is used, and the polyurethane foam impregnated with activated carbon is the bottom layer, which can be attacked by poisonous gas. Provide temporary protection. There are many types of respirator, but in terms of structure and working principle, they are mainly divided into two categories: air filter masks and air supply masks.
(1) The air filter type mask, or simply the filter type mask, works by filtering the air containing the harmful substances through the filter material of the mask and then inhaling it. 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 dustproof and chemical filter box for anti-virus.
(2) Air supply mask refers to a clean air source that will be isolated from harmful substances. It can be sent to the person's face for breathing through the tube and mask through dynamic action such as air compressor and compressed gas cylinder device.

There are many types of medical disposable masks, and we usually divide them into air-supply medical disposable masks and air-filtered medical disposable masks. Moreover, in medical disposable masks, air-filtered medical disposable masks are mainly used to prevent harmful gases from entering the human body through the air, thereby enabling filtration. In the air supply type medical disposable mask, the harmful substances are isolated and the movement is used to provide breathing through the mask. In comparison, filter-type medical disposable masks are used more.
