Product Details
Disposable masks are made of more than three layers of 28g non-woven fabrics; the nose bridge is made of environmentally friendly all-plastic strips, does not contain any metal, is equipped with breathable, warm and especially suitable for electronic factories, daily life use. Disposable masks (medical surgical masks) can prevent respiratory infections at a certain level, but cannot prevent haze. Attention should be paid when purchasing, should choose the mask clearly marked "Medical surgical mask" on the outer packaging
Size 17.5cmx9.5cm, 50 pcs / box, 2000 pcs / 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 fabrics and filter paper; disposable three-layer masks are made of two layers of fiber non-woven fabrics professionally used in medical and health, with an additional layer in the middle to filter and prevent bacteria up to 99 More than% of the filter solution spray cloth is made by ultrasonic welding. The nose bridge is made of environmentally friendly all-plastic strips, does not contain any metal, and is equipped with steam permeable and warm. The filter effect BFE is up to 99%, which is especially suitable for electronic factories; the disposable activated carbon mask is made of 28 grams of non-woven fabric on the surface, and the first layer in the middle is anti-bacterial filtering paper with anti-bacterial filter paper of 99%, which plays an anti-bacterial role To avoid virus hazards; the middle second layer is made of new-type high-efficiency adsorption and filtering materials-activated carbon fiber and activated carbon cloth, which has the effects of anti-virus, anti-odor, filter bacteria and dust resistance;
Disposable masks are manufactured with environmentally friendly all-plastic nose bridges. The design of the nose bridge clip can be adjusted to the most warmth according to different face shapes. The inner ultrasonic spot welding is used, the ear straps are very strong and not easy to fall.
Disposable masks can be used in electronics manufacturing, dust-free workshops, catering services, food processing, schools, locomotives, spray processing, stamping hardware, electroplating, chemical, steel, electric welding, health centers, hand processing industry, hospitals Beauty, pharmaceuticals, factories, environmental cleanliness, public places, and other useful methods: Hang elastic ears on both ears, with full nose type, gently press the fixed piece to fix, so that the mask fits the face. The main technical indicators of the product: Carbon tetrachloride adsorption rate:> 70% benzene adsorption rate: ≥15% resistance: 80% area weight: 35 ～ 45g / m2. Remarks: 1. Size: 9CMx17.5 2. Product.
Everything has its two sides, as is the disposable mask. It has some advantages while having some advantages:
advantage
Advantages: Very good ventilation; can filter toxic gases; can keep warm; can absorb water; can be waterproof; flexible; will not be messy; feels very good and very soft; relative to other masks, the texture is lighter; Very elastic, can be recovered after stretching; the price is relatively low, suitable for mass consumption;
defect
Disadvantages: Compared with other cloth masks, disposable masks cannot be cleaned; because the fibers are arranged in a certain direction, they are easier to be ripped apart; compared with other textile cloth masks, the strength and strength of disposable masks Durability is worse than other masks.
There are a variety of disposable dust masks, which must be selected according to different operating needs and working conditions.
The choice should first be based on the dust concentration and toxicity. According to GB / T18664 "Respiratory protective equipment selection, use and maintenance", as a half mask, all dust masks are suitable for environments where the concentration of harmful substances does not exceed 10 times the occupational exposure limit, otherwise a full mask or protection level should be used Higher respirators.
If the particulate matter is a highly toxic substance, carcinogen and radioactive, the filter data with the highest level of filtering efficiency should be selected.
If the particulate matter is oily, be sure to select the applicable filtering data.
If the particulate matter is needle-shaped fiber, such as slag wool, asbestos, glass fiber, etc., because the dust mask can not be washed, the mask with the tiny fiber is likely to form facial irritation at the face sealing part, which is not suitable for use.
For high-temperature and high-humidity environments, it is warmer to choose a mask with an exhalation valve. Selecting a mask that can remove ozone can be used for welding to provide additional protection. Poison combination filter element. For environments where there is no particulate matter, but only certain odors, choosing a dust mask with an activated carbon layer is much more cumbersome than wearing a gas mask, such as some laboratory environments, but due to national standards, technical performance standards for such masks are not stopped .
How to use
1. Wash your hands before wearing a mask.
2. Hold the ear strap with both hands, and put the dark side on the outside (blue) and the light side on the inside (white suede).
3. Put the side of the mask with a wire (a small piece of hard) on the nose, squeeze the wire according to my nose shape and pull the mask body completely down, so that the mask completely covers the nose and nose.
4. One-time masks are usually replaced in 8 hours and cannot be used repeatedly.
Things to keep in mind
1. Please use the disposable mask within the validity period.
2. Only for one-time use and destruction after use.
3. The packaging is damaged, and its use is prohibited.
4. Pay attention to the date of consumption.
Storage conditions
Disposable masks are stored in a room with a relative humidity of no more than 80%, no corrosive gases and well-ventilated rooms to prevent high temperatures.
