1. The composition structure of masks
There are various types of masks, and each type has its specific application scope and structural principle.
1.1 Components
The various components of a mask include a colored waterproof layer, a filter layer, absorbent non-woven fabric, metal strips and protective ropes. Each part has a special function to ensure protection and stability. The waterproof layer is usually blue, red or green and can effectively prevent droplet infection. The filter layer is the key part in a mask responsible for filtering bacteria and dust. Water-absorbing non-woven fabric can absorb saliva produced by the wearer. The design of the metal strip aims to enhance the stability of the mask and prevent it from falling off. The protective straps are responsible for hanging the mask over both ears to ensure a tight fit to the face.
1.2 Enhanced Design
Design features that enhance the protective power of masks, such as the stability of metal strips and the fit effect of protective ropes, increase the comfort and safety of wearing.

2. Classification and Functions of Masks
2.1 Protective masks
Protective masks are made of one or more fabrics that can effectively isolate virus aerosols, virus-containing liquids and other substances. They are made of suitable materials and have properties such as low air resistance and synthetic blood barrier. This mask features a self-priming design that maintains a barrier against viral aerosols, virus-containing liquids, etc. throughout the breathing process. It is specially designed for medical environments to prevent the spread of viruses from patients to medical staff.
2.2 Surgical masks
Surgical masks are mainly composed of face shields, shaping parts, straps and other components, and are usually made of nonwoven fabric materials. Its isolation effect is mainly achieved through the filter material, which can effectively prevent the direct filtration of pathogenic microorganisms, body fluids, particulate matter, etc. This type of mask is suitable for medical staff in operating rooms, providing two-way protection for both medical staff and patients and preventing the spread of microorganisms and liquids.
2.3 Medical masks
Medical masks consist of a face shield and the connection part of the mask. They have undergone sterilization treatment and are for single use only. Most of them adopt a self-priming filtration design and are suitable for clinical medical staff to wear during invasive procedures. This type of mask provides basic protection but is not suitable for products with new functions.

3. The applicable scope of various masks
3.1 Scope of application of medical Protective masks
Medical protective masks are specially designed for medical staff and related workers. They have a high protection level and can effectively block harmful substances such as virus aerosols and virus-containing liquids. They are suitable for the protection against respiratory infectious diseases.
3.2 Scope of application of medical surgical masks
Medical surgical masks are suitable for basic protection of medical staff or related personnel in clinical environments. It can effectively prevent the spread of blood, body fluids and splashes, and is suitable for invasive operations.
3.3 Application Scope of Ordinary disposable medical masks
Ordinary disposable medical masks can be used for one-time hygiene care in ordinary environments. They are affordable. Although their protective effect against pathogenic microorganisms is not definite, they can be used for daily protection.
