Can 3M9001V masks protect against chemicals produced by rosin burning

Hello! We are happy to answer for you, rosin combustion products have a complex composition, in addition to particulate matter, there are also gaseous substances of unknown composition. In the case you mentioned, it is recommended that you choose an anti-particulate respirator with activated carbon and a filtration efficiency of at least KN95 (95% efficiency), such as 3M 8247 (NIOSH R95) or 3M 8577 (NIOSH P95) Both masks have a small amount of activated charcoal that you can use to see if it works.

We hope you are satisfied with the above reply! If you still have questions, please feel free to ask the company.

A: You said that non-woven masks are, of course, non-woven fabrics. Common mask classifications:

The common masks on the market now include industrial, medical, and general civilian. Regardless of the category, you have to choose a high-grade mask.

Industrial masks have the characteristics of high protection, extensive and low cost, and do not focus on aesthetics and comfort.

Ordinary civilian masks often only play a role in keeping warm and decorating, and the cost is not too high.

There are two types of medical masks: ordinary and advanced. The cost of ordinary medical masks is not high, and the protection is not outstanding; High-grade medical masks are used by surgeons or dentists, focusing on the filtration of particulate matter and the barrier to fluids, so as to ensure the breathability of wearing in a precise working environment.

The characteristics of Puweixin: in line with the highest standards of the United States, the United States imports the official website of Beijing is very good, and the details can be connected.

The landlord good flux tin strip DXT-398A thinks that it is better to work in a ventilated environment. Let's install an exhaust fan.

The chemical components of rosin mainly include rosin acid, pepper acid, etc. The gases produced by the oxidation of these substances (which also contain tar) have a strong prickly smell, and when inhaled by the human body, the tar will accumulate in the lungs, causing lung tissue lesions, similar to smoking. However, small amounts of these gases do not cause discomfort to the human body.

Industrial rosin is mainly used in paint, papermaking, rubber manufacturing, etc. It is not very toxic to the human body, but because it often contains heavy metals such as lead and toxic compounds, as well as peroxides produced after oxidation, it will seriously affect human health. The traditional Chinese medicine rosin must go through strict quality testing, and the content of various toxic substances must meet certain standards before it can be used in medicine.

Pure rosin is not harmful to the human body, but inhalation of rosin dust will cause harm to the human respiratory system, and rosin powder will condense when exposed to water, which is difficult to remove. In addition, when rosin is not completely burned, toxic and harmful substances will be released, so attention should be paid to maintaining good ventilation and wearing protective equipment (such as masks) during construction

The lead content of rosin is somewhat high, and the lead is not excreted after being eaten, and the deposition will cause varying degrees of damage to the intelligence of children in the process of growth. Rosin becomes more and more toxic after repeated use. When heated at high temperatures, duck feathers and rosin will produce high-temperature oxidation, and the substances produced are more complex and the damage to the human body is greater.

It may or may not be lethal.

Oh my God, I just learned that you can't use rosin to dehair ducks, my family has used it, but I don't know if it will be harmful, I see a lot of pine forests with bags to collect rosin, it is estimated that it is used for dehairing.
