Does the mask have a protective effect on the dust of FRP?

Masks can effectively prevent the harm of FRP dust to the body.

However, not all masks can effectively protect against ultra-fine dust or toxic dust.

After FRP dust is inhaled, it can cause lung stromal tumors.

It can also cause respiratory tracts.

and lung inflammation, for the sake of good health, it is recommended to do a good job of respiratory protection. The current high-grade mask has changed the characteristics of poor breathing in the past, and the level of protection.

High, breathe as smoothly and at a very low cost.

1. Dust masks belong to special labor insurance and must be certified by GB2626-2006. You can't use a normal mask.

2. Dust masks have a protection level according to the national standard. Low N90, Medium N95, High N100. Among them, N100 can protect against ultra-fine dust. For good protective effect, it is recommended to choose a KN100 grade dust mask.

3. Dust masks are available in sizes according to the national standard. You should choose the right size according to your head shape, and the sealing effect is good.

4. Try to choose a breathable one. Some manufacturers adopt a double-sided, double-piece design, and the breathing resistance is basically not felt.

5. Try to choose long-lasting cotton filters. Some manufacturers use long-lasting filter cotton, which has low breathing resistance, and the filter can be used for nearly a month. The average daily cost is one dollar. Such masks are easily accepted by the general public.

On December 21, 2015, **10, 13:22 Truth Column, there was a report on how to choose a mask.

It is recommended to use a silicone dust mask, which can be replaced with inner core filter cotton, particulate filter cotton and activated carbon filter cotton.

Anti-smog masks are OK, and you can go to Beijing Jiakang Times Medical Equipment to buy them.

Dust masks are used to filter fine dust particles in the air, so they are called dust masks and anti-particulate respirators.

In China's respiratory protection standard GB2626-2019, it is clearly stipulated that the pre-level of dust mask protective rubber is divided into three levels: KN100, KN95 and KN90, of which KN100 is the highest protection level.

KN100 is the highest protection level of Liang Heqing dust mask, which can filter fine dust particles; The KN95 has only 95% filtration efficiency, and the KN90 can only reach 90% filtration efficiency.

The higher the filtration efficiency of the dust mask, the less fine dust is inhaled, and the less likely it is to develop pneumoconiosis.

Summary. Prevent or reduce the entry of airborne dust into human respiratory organs.

In addition to dustproofing, it can also prevent droplets, aerosols, bacteria, and viruses.

What hazards to prevent with a dust mask.

Prevent or reduce the entry of airborne dust into human respiratory organs. In addition to dustproofing, it can also prevent droplets, aerosols, bacteria, and viruses.

Prevent the harm of dust in the air into the respiratory organs.

Dust masks are indispensable protective equipment for workers engaged in and exposed to dust. It is mainly used in work environments containing low concentrations of harmful gases and vapors, as well as in work environments where dust is generated. The cartridge contains only adsorbents or absorbents.

Some cartridges are also equipped with a filter layer to protect against aerosols at the same time. Some military gas masks, mainly made of activated carbon cloth, or with an outer layer of water- and oil-resistant fabric, an inner layer of glass fiber filter material, and a base layer of polyurethane foam impregnated with activated carbon, can provide temporary protection in the event of a sudden gas attack.

Material: Most of the dust masks are constructed with two layers of non-woven fabric inside and outside, and a layer of filter cloth (meltblown cloth) in the middleFiltration principle: The filter of fine dust mainly depends on the filter cloth in the middle, because the meltblown cloth has the characteristics of static electricity, it can adsorb very small particles.

Because the fine dust is adsorbed on the filter cloth, and the filter cloth cannot be washed with static electricity, the dust masks are disposable.

Hope mine is helpful to you.

Yes;Masks can be selected according to the characteristics of harmful substances:

1. Particulate matter protective masks.

3M particulate matter protective masks are commonly known as 3M dust masks. The use of protective masks at work to protect the health of workers falls under the category of occupational hygiene. Particulate masks are used to reduce the amount of harmful particulate matter (from coarse sand and dust, fumes, fumes, air pollutants, and fine pathogens) suspended in the air through the respiratory tract.

Particulate masks have different levels of filtration efficiency from low to high, which are specified by the standard to which the product applies, for example, the Chinese National Standard GB2626-2006 specifies 3 levels of filtration efficiency97%）。3M anti-particulate matter masks are widely used for occupational protection, aiming at the particulate matter generated in the production process, such as mineral dust, casting smoke, welding smoke, drug dust, wood dust, etc., ** for this type of application of specific regulations, standards, specifications and guidance for the selection, usually, 90% filtration efficiency level can be used for all kinds of low-toxicity dust, but it is not recommended for smoke (such as welding smoke) protection; The 95% level is suitable for smoke (such as welding fumes), highly toxic dust (such as heavy metal lead, cadmium, etc. and pharmaceutical dust) and pathogenic microorganisms (such as influenza virus), and the level is suitable for more toxic and harmful particulate matter, such as radioactive dust, carcinogens, etc.

2. Features of masks with activated carbon layers:

It is to add a thin layer of activity to the particulate protective mask.

Carbon or other gas-adsorbed materials can reduce some low-concentration gases with unpleasant tastes, that is, reduce odors and improve breathing comfort. For example, the odor emitted by putrefactive substances (mainly organic substances).

When the concentration of odorous gases is high enough to be harmful to health, a gas mask is required.
