Analysis of the Material and Function of Medical Masks

Ⅰ. What is the medical face mask made of?

The material of medical masks is generally based on non-woven fabrics, which are light and have high filterability. The mask is divided into three layers: inner, middle and outer, which are made of non-woven fabric or ordinary sanitary gauze; ultra-fine polypropylene fibre melt-blown material; non-woven fabric or ultra-thin polypropylene melt-blown material. Among them, medical masks are divided into three kinds of masks, and ordinary medical masks are not waterproof.

Medical 3-layer masks are generally divided into three layers: inner, middle, and outer. The inner layer is generally non-woven fabric or skin-friendly material made of ordinary sanitary gauze; the middle layer is generally an isolation filter layer made of ultra-fine polypropylene fibre melt-blown material; the outer layer is generally non-woven fabric or ultra-thin polypropylene melt Special antibacterial layer made of spray material.

There are three types of medical masks, namely ordinary medical masks, medical surgical masks, and medical protective masks. Among them, medical surgical masks and medical protective masks are often used in hospitals, and their protection and filtering properties will be better. The ordinary medical 3 layer face mask has a high filtration rate, but it is not waterproof, so it must be changed frequently when it is worn.

Ⅱ. What are the functions of the medical face mask in other industries?

Medical masks are a kind of protective medical supplies often used in the medical industry, and medical masks are also used in other industries. In some industries that contain toxic gases or steam, medical masks are also used.

Medical masks are dust-proof and anti-toxic, and can filter substances that are toxic to the human body. Disposable masks are very important to health. Woven yarn dust masks protect the respiratory organs of personnel from harmful substances. Respiratory protection equipment is generally composed of a mask and a poison filter box. The filter box contains an adsorbent, which has a very good adsorption effect. Some filter boxes are also equipped with a filter layer to prevent aerosols at the same time. And the medical supplies manufacturer focuses on the research more and more.

The anti-virus 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 fibre filter material as the inner layer, and activated carbon-impregnated polyurethane foam as the bottom layer, which can be suddenly attacked by poisonous gas. Provide temporary protection at times. There are many types of gas masks, 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 filtering disposable face mask is referred to as the filtering mask. Its working principle is that the air containing harmful substances is filtered and evolved by the filter material of the mask before being inhaled by people. 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 disposable mask refers to a clean air source isolated from harmful substances, which is delivered to the face of a person through a tube and a face mask through a power action such as an air compressor, a compressed gas cylinder device, etc., for people to breathe.
