The role and variety of masks
Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, when working in dust and other polluted environments, wearing masks has a very good effect. China is the first to use masks in the world. In ancient times, in order to prevent dust and breath pollution, people in the palace began to use silk scarves to cover their mouth and nose. It was not until the 19th century that masks were invented and started to be used.
In the medical field. It has become an indispensable item in people's lives, and it is no longer just dust or breath, but is often used to block germs.
1. Medical mask
A medical mask is composed of a mask face and a tightening belt. The face of the mask is divided into three layers: inner, middle and outer. Non-woven fabric. This high-efficiency medical mask has strong hydrophobic and air permeability, has a significant filtering effect on small virus-carrying aerosols or harmful dust, the overall filtering effect is good, and the materials used are non-toxic, harmless and comfortable to wear. It is suitable for the protection of medical staff and related staff against air-borne respiratory infectious diseases. The high level of protection is attracted by static electricity and adsorbed on the filter material to capture fine dust, which really plays a role of dust blocking.
2. PM2.5 mask
A mask that can effectively filter PM2.5 particles. The airtightness of the multiple layers of the mask determines the ability to filter suspended particles. It can effectively filter the invisible killers in the air-viruses, dust mites, smog, volatile chemicals, etc.
In addition to being dustproof, PM2.5 masks can also prevent PM2.5. The mask fabric is made of Kanglun fiber that can kill "super **" that can't kill even ***.
The PM2.5 mask has good air permeability, dustproof, virus and anti-**, and it is particularly comfortable to wear. Use three-dimensional cutting, close to the face design, reserved space to make your breathing easier. The inner layer
High-quality material, gentle and close to the skin, comfortable to wear. In addition, there are plastic nose strips, which are closer to the shape of the nose and make the mask more effective.
Three, anti-fog mask
The anti-fog medical mask consists of a high-transparency anti-fog lens combined with a disposable mask to form a whole, which can effectively avoid infections caused by blood and body fluids splashing to medical staff during the process of receiving medical treatment and accident treatment. . This product can also effectively protect people who work in dangerous environments such as scientific research laboratories, forensic anatomy, and solid splashing.
With its unique pleat design, it can prevent liquid polymerization, and the internal and external water-resistant design reduces the risk of pollution. The special three-anti-material on the surface can be used to prevent alcohol, blood, and oil. In addition,
The unique anti-fog lens integrated with the mask is easy to wear and provides safe protection. The mirror surface adopts high-strength heat sealing, which can withstand general gravity pulling without falling off.
