Classification of dust masks

Dust respirator is an indispensable protective equipment for those who are engaged in and exposed to dust. Low working environment and dusty working environment. Filter boxes contain only sorbent or sorbent. Some cartridges also contain a filter to keep out aerosols. Some military protective masks mainly use activated carbon cloth, or waterproof and oil-resistant fabric as the outer layer, glass fiber filter material as the inner layer, and polyurethane foam soaked in activated carbon as the bottom layer, which can provide temporary protection in case of sudden gas attack.

Dust masks There are also many kinds. But their principles are the same: they all use composite filter materials. The general filter materials are: activated carbon fiber, activated carbon particles, melt-blown non-woven fabric, electrostatic fiber, and of course there are other special filter materials, which are mainly used to process other special materials. Toxic gases or radioactive particles, etc. The classification of dust masks is similar to that of other masks. We can also classify them according to how many times they are used and how they look.

According to the number of uses: it can be divided into disposable respirator dust respirator, multiple respirator respirator Dust masks and recyclable respirators.

Divided according to the appearance: it can be divided into half mask type, comprehensive belt type, flat cup type and duckbill type.

duckbill

The duckbill dust mask adopts a boat-shaped design, the outer nose clip line is adjustable, and the inner sponge strip is adjustable. The design of the elastic band is more in line with the mechanical requirements, and has good sealing performance. It can go around the ears and pass through the head, so as to avoid ear discomfort caused by wearing a mask for a long time.

The three-dimensional design of the duckbill mask makes conversation more convenient, especially suitable for clean rooms, medical use to prevent bacterial and viral infections , Industrial use to block tiny dust. This product is a fully automatic production line.

Its inner and outer layers are made of soft PP non-woven fabric, which can reduce fiber shedding.

The filter layer adopts melt-blown material, which can effectively prevent dust and non-oily particles in the air. Applications: construction, mining, textile, grinding, cement, glass, hardware and other industries.

with breather valve

The dust mask is designed with an exhalation valve to reduce heat accumulation and make breathing easier, suitable for long-term use in high temperature and high humidity environments, odorless, non-allergic, raw materials. Adjustable nose clip, high filtration efficiency, low resistance, making the mask and face airtight, dust is not easy to leak into the filter layer after electrostatic treatment, effectively filters and absorbs fine harmful industrial dust, prevents silicosis ultrasonic welding, elastic band polyurethane fiber The material is more effective in protecting the wearer: construction industry, agriculture and animal husbandry, food processing industry, cement factory, textile factory, cutting dust, workplaces with heavy metal harmful pollutants.
