disposable mask

Outer layer of mask: PP non-woven fabric, inner layer of mask: solution spray non-woven fabric (filter paper), inner layer of mask: PP non-woven fabric

Mask packaging: 50 pieces / box, 1000 pieces / box

Disposable masks can be applied to: electronic manufacturing, catering services, food processing, schools, motorcycles, handicrafts, factories, environmental cleaning, but also suitable for construction, stone, textile, grinding, metal casting, electronics, material processing and grinding and other protective dust-proof operations.

Characteristics of disposable mask materials


Everything has its two sides, the same with disposable masks. It has advantages and disadvantages at the same time:


Advantage


Advantages of disposable mask: very good ventilation; can filter toxic gas; can keep warm; can absorb water; can waterproof; has scalability; will not be messy; feel very good and quite soft; relatively light texture compared with other masks; very elastic, can be reduced after stretching; low price, suitable for mass production;

shortcoming


Disadvantages of disposable masks: compared with other cloth masks, disposable masks can't be cleaned; because their fibers are arranged in a certain direction, they are easy to tear; compared with other textile cloth masks, the strength and durability of disposable masks are worse than other masks.


Use conditions of disposable masks


There are various kinds of disposable dust masks, which must be selected according to different operation requirements and working conditions.

First, the disposable mask should be selected according to the dust concentration and toxicity. According to the selection, use and maintenance of respiratory protective equipment (GB / t18664), as a half mask, all dust masks are suitable for the environment where the concentration of harmful substances does not exceed 10 times of the occupational exposure limit, otherwise, a full mask or respirator with higher protection level should be used.


If the particles are highly toxic, carcinogenic and radioactive, the filter material with the highest filtration efficiency should be selected as a disposable mask.


If the particles are oily, be sure to select the appropriate filter material as a disposable mask.

If the particles are needle like fibers, such as slag cotton, asbestos, glass fiber, etc., due to the dust-proof disposable mask can not be washed by water, the mask with micro fibers on the sealing part of the face is easy to cause facial irritation, and is not suitable for use.


For high temperature and high humidity environment, the respirator with exhalation valve will be more comfortable. The disposable respirator with ozone removal can be used for welding to provide additional protection. However, if the ozone concentration is higher than 10 times of the occupational health standard, the mask can be replaced with dust and poison combination filter elements. For the environment with no particles but only some peculiar smell, the dust-proof disposable mask with active carbon layer is much lighter than that with gas mask, such as some laboratory environment, but the national standard does not regulate the technical performance of this kind of disposable mask.
