Description
Technical field
The present invention relates to a kind of anti-PM2.5 masks, more particularly to a kind of active carbon mask of anti-PM2.5.
Background technology
Mask be worn over nose and mouth for filter disengaging mouth and nose air, to reach the gas of blocking harmful, smell, winged
Foam passes in and out the apparatus of wearer's mouth and nose, is mostly made with cloth or paper etc..PM2.5 is that diameter is less than or equal to 2.5 microns in air
Pellet, PM2.5 contain pernicious gas and heavy metal substance, and PM2.5 is small and light, it is difficult to which natural subsidence is to ground
On, long-term floating in air, and adsorbs a large amount of poisonous and harmful substances, thus very big to human health damage.Exploitation is a kind of
It can effectively stop that the mask of PM2.5 has become a top priority.But traditional mask generally use multilayer gauze or nonwoven
Cloth overlapping is fabricated to mask, mask covering mouth and nose during use, in order to reached molecule in air filtering or
Either the number of plies of non-woven fabrics or increase gauze or non-woven fabrics when aerial dirt count is very big it is necessary to increase gauze
Textile density, the permeability of such mask will reduce, in use, people can be allowed to breathe difficulty increase, feel bored, breathe out simultaneously
Moisture row do not go out, people is allowed to feel very uncomfortable.The present invention has studied a kind of anti-PM2.5 mouthfuls containing activated carbon non-woven layer of cloth
Cover, active carbon nonwoven fabric have good absorption property, and thickness is uniform, good permeability, free from extraneous odour, and carbon content is high, activated carbon
Grain is not easily to fall off, and PM2.5, microorganism, virus etc. in air filtering were come by the good adsorptivity of activated carbon, prevents air dirty
Dye endangers health.
The anti-PM2.5 active carbon masks of invention, good permeability, light comfortable, hygienic environment-protecting, the active carbon nonwoven fabric contained
Layer can in environment PM2.5, dust particle, sulfide, nitride, organic hydrocarbon compounds, metal ion and bacterium, virus
Etc. the multiple isolation of harmful substances, remove harmful substance, clean, safe air be provided for human body.
