Lead generally comes from the oxide of lead that is emitted during the refining process. Lead poisoning can occur when inhaled. For respiratory protection, it is recommended to choose a KN100 grade dust mask for protection.
Choose a dust mask scientifically, choose a good mask with good protective effect, smooth breathing, and economical use. Helps prevent lung damage from occurring. The way to clean the dust:
Now dust masks must implement the GB2626-2006 standard. Dust masks are divided into three grades: KN100, KN95 and KN90. Among them, KN100 can achieve nearly 100% (more) protection effect against ultrafine dust.
If the granularity is large, KN95 grade can be selected. The effectiveness of protection depends on 2 aspects. One is the filtration efficiency of the filter cotton.
The second is the air leakage rate after the mask is mated to the face. Therefore, masks must be divided into large and small sizes, and the air leakage rate between masks and faces varies from person to person. The way to clean the dust:
The scientific selection of dust masks certified by the GB2626-2006 standard helps to prevent lung damage. 1. Choose a duplex half mask type. Disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate.
2. Select KN100 level. A high dust environment with a low protection rate will lead to physical injury. 3. Choose a silicone mask, which has a relatively long service life, soft and comfortable.
Wear it for a long time and it is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation. 4. Masks are divided into large and small sizes, which is extremely important.
It is not recommended to buy those so-called universal models of masks, which are prone to air leakage. 5. There are two types of masks covering the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable. 6. It is recommended to choose a breathing mask.
Some masks are designed with double filter cotton + double filter surface, which is relatively smooth to breathe and has a long service life. It is recommended to evaluate occupational protection from the above quality, grade, comfort and economy, and choose a good mask that can effectively prevent pneumoconiosis.

If it is only dustproof and non-oily particles, it is recommended to choose a KN95 or N95 dust mask, such as 3M 9500 series, Honeywell H901V, 3M 9334CN+ (trench choice) and so on. The above only applies to non-oily particulate matter.
If your working environment will also be exposed to toxic and harmful gases, it is recommended to buy a half-mask or full-face gas mask, such as 3m, etc., and choose the corresponding filter box according to the specific type of toxic and harmful gases.
As for the difference between non-oily particulate matter and oily particulate matter, the choice of the corresponding mask, the choice of gas mask filter cartridge. and so on, one or two sentences can not be clear, you can find our company to understand.

Beanda is the only company in China that has passed the highest respiratory protection level of N100, and its respirator has three main protection features, 1Face Mask 2...Breathing valve 3
Filter cotton. The mask is made of silicone, which is soft, non-toxic and odorless, age-resistant, and has excellent skin-friendliness. If the mask does not combine well with the face, it is equivalent to no protection, but this does not occur with the Beanda mask.
Breathing valve, each breathing valve is strictly inspected (every one is inspected), the breathing valve is very important, if it does not play a sealing dust, it will enter the human mouth, which is equivalent to no protection.
Cotton filter, Baianda filter cotton is a foreign technology, produced from the United States and then processed in China, because there is no domestic manufacturing N100 level equipment, Baianda filter cotton is the use of electrostatic adsorption function, so that no matter how small the dust can only stay outside, so that your breathing is better and clearer. Moreover, the filter is double-sided, so that the breathing resistance is better and lower. In addition, I recommend a few anti-virus filter cartridges.
a-1301
Protection objects: organic vapor, benzene and its homologues, gasoline, acetone, carbon disulfide, ether and other E-1301
Protection object: chlorine, sulfur dioxide, hydrogen sulfide, nitrogen oxides and other acid gases K-1301
Protection object: ammonia and ammonia derivatives.
