Disposable non-woven cloth mask is made of two layers of non-woven cloth and filter paper;The disposable three-layer mask is made of two layers of professional non-woven fabric used in medical care, with an additional layer in the middle to filter and prevent bacteria up to 99% of the filter dissolved spray cloth, which is welded by ultrasonic wave.Filtering effect up to 99% B.F.E is particularly suitable for electronic plants;Disposable activated carbon mask is the surface layer of 28 grams of non-woven cloth, the middle of the first layer is the use of anti-bacteria filter paper to filter bacteria up to 99% to play a role in anti-bacteria, to prevent virus damage;The middle second layer is made of activated carbon fiber and activated carbon cloth, which are new effective adsorption and filtration materials.
Disposable mask in the production is the use of environmental protection plastic nose bridge strip nose bridge clip design can be made according to different face shape the most comfortable adjustment.With ultrasonic spot welding inside, the ear band can be very firm and not easy to fall off.
Disposable masks can be applied to electronic manufacturing, dust-free workshop, catering services, food processing, school, riding motorcycles, spraying processing, hardware stamping, electroplating, chemical industry, steel, welding, institutes, hand processing industry, hospital, cosmetic, pharmaceutical, etc. Various factories, clean environment, public utility method of use: elastic ear GouGua on ears, with total nasal type, gently press stator fixed, make the face mask and facial joint.
Main technical indicators: carbon tetrachloride adsorption rate :>70% benzene adsorption rate :≥15% resistance force :80% area weight :135~145g/m2.Size: 9 cmx17. 5
Everything has its two sides, disposable mask is the same, it has some advantages while also has some disadvantages:
Advantages: very good ventilation;Can filter toxic gases;Able to keep warm;Water absorption;Waterproof;Flexible;Not messy;Feel very good and quite soft;Compared with other masks, the texture is relatively light;Very elastic, can be reduced after stretching;Relatively low price, suitable for mass production;
Disadvantages: compared with other cloth masks, disposable masks can not be washed;Because the arrangement of its fibers has a certain direction, so it is easier to be torn;Compared with other textile masks, the strength and durability of disposable masks are worse than other masks.
Disposable dust respirators are available in a variety of ways and must be selected according to different operating requirements and working conditions.
If the particles are highly toxic, carcinogenic and radioactive, the filtration material with the highest filtration efficiency should be selected.
If the particles are oily, be sure to choose the appropriate filter material.
If the particulate matter is needle-like fiber, such as slag wool, asbestos, glass fiber, etc., since the dust mask cannot be washed, the mask coated with tiny fiber is easy to cause facial irritation in the face sealing area, and is not suitable for use.
For the high temperature and high humidity environment, choose the mask with breathing valve will be more comfortable, choose the mask that can remove ozone for welding can provide additional protection, but if the ozone concentration is higher than 10 times of the occupational health standard can be replaced mask, dust, poison combination filter elements.In the absence of particulate matter, but only some odor of the environment, the choice of the dust mask with activated carbon layer than wearing a gas mask is much lighter, such as some laboratory environment, but because the national standards do not this kind of mask technical performance specifications.
