Disposable protective masks can be divided into disposable flat masks and disposable three-dimensional masks. Three-dimensional masks can be divided into: disposable cup masks, disposable folding masks, disposable duckbill masks.
Disposable protective mask material: non-woven fabric, meltblown filter cotton conventional size: 17.5cmx9.5cm
Disposable protective masks are made of more than three layers of 28 grams of non-woven fabric; the bridge of the nose is made of environmentally-friendly all-plastic strips, contains no metal, is equipped with breathability, and is particularly suitable for electronics factories and daily use.
Features of Disposable Protective Mask
Size 17.5cmx9.5cm, 50 pieces / box, 2000 pieces / carton, disposable masks are divided into disposable three-layer masks, disposable non-woven masks, disposable four-layer masks, disposable activated carbon masks.
Disposable three-layer masks are made of two layers of non-woven fabric and filter paper. Disposable three-layer masks are made of two layers of fiber non-woven fabrics that are professionally used for medical and health. More than% of the filter dissolve spray cloth is made by ultrasonic welding. The nose bridge is made of environmentally-friendly all-plastic strips. It does not contain any metal. The filtering effect of BFE is as high as 99%, which is especially suitable for electronics factories; disposable activated carbon masks use a surface layer of 28 g of non-woven fabric, and the first layer in the middle is made of antibacterial filter paper to prevent bacteria by 99%. , To prevent virus damage; the second layer in the middle is made of a new type of high-efficient adsorption and filtering material-activated carbon fiber, activated carbon cloth, which has the functions of anti-virus, deodorization, bacteria filtration, and dust blocking;
Disposable protective masks are manufactured with environmentally friendly plastic nose bridge strips. The nose bridge clip design can be adjusted most comfortably according to different face shapes. With the optional ultrasonic spot welding, the earbands are very strong and will not fall easily.
Disposable protective masks can be used in electronics manufacturing, dust-free workshops, catering services, food processing, schools, motorcycles, spray processing, stamping hardware, electroplating, chemicals, steel, welding, health centers, handicrafts, Beauty, pharmacy, factory, environmental cleaning, public places and other uses. Use: hook the elastic ears on both ears, with a full nose type, and gently press the fixed piece to fix the mask to the face. Product main technical indicators: Carbon tetrachloride adsorption rate:> 70% Benzene adsorption rate: ≥15% Moisture resistance: 80% Area weight: 35 ～ 45g / m2. Remarks: 1. Size: 9CMx17.5 2. Product.
Material characteristics of Disposable Protective Mask
Advantages: very good air permeability; can filter toxic gases; be able to keep warm; can absorb water; be waterproof; have elasticity; will not be messy; feels very good and quite soft; Very flexible, can be reduced after stretching; the price is relatively low, suitable for mass production;
Conditions of Use
There are various types of disposable dust masks, which must be selected according to different operating requirements and working conditions.
The first choice should be based on the concentration and toxicity of the dust. According to GB / T18664 "Selection, Use and Maintenance of Respiratory Protective Products", as half masks, all dust respirators are suitable for environments where the concentration of harmful substances does not exceed 10 times the occupational exposure limit, otherwise a full face mask or protection level should be used Higher respirator.
If the particulate matter is oily, be sure to select a suitable filter material.
If the particulate matter is needle-shaped fibers, such as slag wool, asbestos, glass fiber, etc., since the dust mask cannot be washed, the mask with microfibers on it will easily cause facial irritation at the face seal, and it is not suitable for use.
For high-temperature and high-humidity environments, choosing a mask with an exhalation valve will be more comfortable. Choosing a mask that can remove ozone can provide additional protection for welding. However, if the ozone concentration is higher than 10 times the occupational health standard, you can replace the mask. Poison combination filter element. For environments where there is no particulate matter but only certain odors, it is much lighter to choose a dust mask with an activated carbon layer than a gas mask, such as in some laboratory environments, but due to national standards, there is no technical performance specification for this type of mask .
Instructions of Disposable Protective Mask
4. Disposable protective masks are usually replaced every 8 hours, and cannot be reused.
