Dust masks(4)
Update time:2016-09-27 09:53:36 Click Num:4027Selection criteria:
First: the dust cover of the mask to be more efficient. The efficiency of dust suppression of a mask is based on its dust on the micro-dust, especially for 5 m below the respiratory dust dust as the standard efficiency. General gauze masks, the principle of dust-proof mechanical filter, that is, when the dust hit the gauze, after a layer of the barrier, some large particles of dust in the gauze. However, the fine dust, especially less than 5 μm of dust, will pass through the gauze mesh into the respiratory system. There are some dust masks on the market for sale, the filter material by filling the permanent electrostatic fibers, those less than 5 μm of respirable dust in the process of passing through this filter material, will be attracted to the electrostatic adsorption in the filter , The real play to the role of dust.
Second: the mask and the face shape of the degree of better adhesion. When the mask is not close to the human face, the dust in the air will be from the mouth around the mask into the respiratory tract. Therefore, people should choose for their face shape of the dust mask and wear a dust mask properly.
Third: wear to be comfortable, including breathing resistance to be small, light weight, wear health, easy maintenance, such as wearing a dust mask masks.
species:
(1) dust protection duckbill type:
Duck-type dust mask with hull design, the external adjustable nose clip, internal sponge, elastic design more in line with mechanical requirements, closed performance, can bypass the ear, across the head, to avoid the Long-term wear masks caused by ear discomfort, improve the wearing comfort.
The three-dimensional design of the duckbill masks make conversation more convenient, especially for clean rooms, medical use to prevent bacteria, virus infection, industrial use to block small dust. This product is fully automated production line production.
The inner and outer layers are made of soft PP non-woven fabric, which can reduce the fiber shedding phenomenon and increase the wearing comfort.
The filter layer uses high-performance melt-blown material, can effectively block dust and air non-oily particles. Applications: construction, mining, textile, grinding, pharmaceutical, cement, glass, metal and other industries.
(2) with a breathing valve:
With breathable design dust mask to reduce heat build-up, make breathing easier, suitable for high temperature, high humidity environment, long-term use of non-toxic, tasteless, non-allergenic, non-stimulating raw materials. High efficiency, low resistance adjustable nose clip, so that the mask and the face of the closed better, the dust can not easily leak into the electrostatic treatment of the filter layer, effectively filter and adsorb very fine harmful industrial dust, to prevent silicosis Ultrasonic welding, spandex silk elastic material to the wearer more effective protection applications: construction, agriculture, animal husbandry, food processing industry, cement plants, textile mills, cutting dust, heavy metals harmful pollutants workplace.
