Description

Filtration formula protective facial mask with from moist water absorption function
Technical Field
The invention relates to the field of protective masks, in particular to a filter type protective mask with a self-moistening water absorption function.
Background
The filtering type mask has long application in daily life, has the effects of filtering bacteria, blocking dust, preventing poison, deodorizing and the like, can effectively block harmful substances such as microorganisms, particles and the like in the air, and ensures the health of human bodies.
The adsorption material such as activated carbon has a large number of micropores in the internal structure and thus has a large specific surface area, so that the adsorption material such as activated carbon can adsorb a large number of toxic gas molecules therein without escaping. Therefore, in order to improve the protection effect on toxic gas, the protective mask adopts the bed layer stacked activated carbon particles or non-woven fabric mixed with activated carbon powder or used as a filtering material, and toxic gas is removed by adsorption and is not inhaled by people. However, the treatment and installation requirements of adsorbing materials such as activated carbon are high, for example, coarse particles can cause inter-particle gaps, and toxic gas can penetrate into respiratory tract from the gaps and is not adsorbed; too fine particles will in turn lead to an increased breathing resistance, with the risk that the activated carbon powder will leak out as dust contaminants.
In the working environment, when the air contains high water-soluble gases such as hydrogen chloride, ammonia gas and the like, common masks and activated carbon masks are difficult to remove through filtering and adsorption. The water absorption can effectively remove the hydrogen chloride, ammonia gas and other polluting gases in the air, but the mask needs to be wetted firstly in use. It is particularly notable that an overly wetted filter will increase air resistance, resulting in poor breathing, and an unevenly wetted filter will fail due to channeling or drift in the contaminated air stream as a result of the dry zone passages. Under the circumstance, for respiratory protection under the emergency escape condition of the dangerous environment, the development of a mask with water wetting property becomes necessary.
