As people's health awareness is becoming stronger and stronger, the demand for respirators is becoming more and more accurate. Today, let's know what a respirator is!
The following knowledge points are listed below:
What is disposable respirators
Advantages and disadvantages of disposable respirators
How to choose disposable respirators
Disposable respirators are made of more than three layers of 28 grams of non-woven fabric; The bridge of the nose is made of an environment-friendly plastic strip, which does not contain any metal and is breathable and comfortable. Especially suitable for electronic factories, daily use. disposable respirators (surgical respirators for medical use) can prevent respiratory infections to a certain extent and cannot prevent haze. Be careful when purchasing respirators that clearly indicate "surgical respirators for medical use" on the outer package.
Disposable respirators are made of environmentally friendly plastic nose strips and nose clips, which can be adjusted according to different face shapes. The inner ultrasonic spot welding, the earband can be very firm and not easy to fall off.
Disposable respirators 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, hospital, cosmetic, pharmaceutical, factories, clean environment, public places such as a variety of purposes Usage: use elastic ear GouGua on ears, with total nasal type, Gently press the fixator to fasten the respirators to the face.
Everything has two sides, disposable respirators are the same, it has some advantages and disadvantages at the same time.
Advantages: very good ventilation; Can filter toxic gas; Can keep heat; It can absorb water; Can waterproof; It is flexible; Will not be messy; It feels very good and quite soft; Compared with other respirators, the texture is relatively light; Very elastic, can be reduced after stretching; The price is relatively low, suitable for large-scale production;
Disadvantages: disposable respirators can't be cleaned compared to other cloth respirators; Because the fibers are arranged in a certain direction, so it is easier to be torn; disposable respirators are less strong and durable than other textile respirators.
There are a variety of disposable respirators, which must be selected according to different operating requirements and working conditions.
The first choice should be based on the concentration and toxicity of dust. According to GB/T18664 "Selection, Use and Maintenance of Resrespiratory Equipment", as a half respirators, all dust respirators are suitable for the environment where the concentration of harmful substances does not exceed 10 times the occupational exposure limit; otherwise, full respirators 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.
If the particles are oily, be sure to select the appropriate filter material.
If the particles are needle-like fibers, such as slag wool, asbestos, glass fiber, etc., the respirator can not be washed with water, and the respirator with tiny fibers attached on the sealing part of the face is likely to cause facial irritation, so it is not suitable for use.
For high temperature and high humidity environment, choose a respirator with an exhalation valve that will be more comfortable, choose respirator with ozone removal for welding can provide additional protection, but if the concentration of ozone is higher than 10 times the occupational health standard, you can replace the respirators, with dust and toxic combined filter element. For the environment where there is no particulate matter but only some peculiar smell, it is much more portable to choose dust respirators with activated carbon layers than to wear gas respirators, such as some laboratory environments. However, due to the national standards, technical performance specifications for such respirators are not carried out.
