This year, along with dense haze weather has appearred continuing in a plurality of provinces and cities of China, and national pay attention to day by day to environmental protection, " ambient air quality " of new revision also increased the PM2.5 monitoring index.These all make people more and more pay close attention to " PM2.5 ".
PM, English full name is particularmatter, is particle.PM2.5 refers to that diameter in atmosphere is less than or equal to the particle of 2.5 μ m, also referred to as entering the lung particle.Its particle diameter too small be difficult for stopped by respiratory tract, can directly enter bronchus and alveolar after being inhaled into human body, disturbs the gas exchange of lung, and causes other diseases.Simultaneously the PM2.5 particle diameter is little, its surface easily be rich in a large amount of poisonous and harmful substances and the time of staying in atmosphere long, fed distance is far away, thereby human body is caused to the threat of multiple health.
Be accompanied by the rapid growth of China's economy, the higher objective reality that become of PM2.5 granule density value in many regional air, pollution for reply PM2.5, the common people have shown great enthusiasm to mouth mask, but the special mouth mask that protects for this superfine particle is also few in the market, on market, the existing mouth mask overwhelming majority uses nonwoven, gauze, plastic net cloth etc. to be prepared from, they knit hole or mesh is all larger, the particle that some are tiny or flue dust can also pass mouth mask and enter nasal cavity.
The utility model content
The purpose of this utility model is to provide a kind of purification PM2.5 mouth mask with replaceable overlay film filter core.Main purpose of the present utility model will solve exactly that present common gauze, non-woven fabrics gauze mask are relative with plastic net cloth mouth mask gap excessively can't stop the PM2.5 particle, utilize the small-bore of microporous teflon membran, effectively realize intercepting the purpose that the PM2.5 particle enters human body, the utility model filter core can also absorbed air in toxic gas, remove peculiar smell, allow the people breathe high-quality air.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of purification PM2.5 mouth mask, with replaceable overlay film filter core, is composited by the first spun-bonded non-woven fabrics layer, melt-blown nonwoven layer of cloth, PTFE microporous film layers, activated carbon non-woven layer of cloth and the second spun-bonded non-woven fabrics layer from top to bottom successively.
Above-mentioned the utility model mouth mask is with replaceable overlay film filter core, and during use, the first spun-bonded non-woven fabrics layer is outside, near air; The second spun-bonded non-woven fabrics layer, inwardly, near population.The PTFE microporous film layers refers to the microporous teflon membran layer.
The utility model the first spun-bonded non-woven fabrics mainly plays protection filter core and the first heavy filtration effect; The in-depth filtration of melt spraying non-woven fabrics plays the second heavy filtration effect; The PTFE microporous barrier plays the more filtration of deep layer; Active carbon nonwoven fabric can be realized further separating fines and remove peculiar smell by absorption, and the second spun-bonded non-woven fabrics layer can play further filtration.
In order to improve the filter efficiency of filter core, guarantee simultaneously its air penetrability, the grammes per square metre of the first spun-bonded non-woven fabrics layer, melt-blown nonwoven layer of cloth, activated carbon non-woven layer of cloth and the second spun-bonded non-woven fabrics layer is 20～30g/m
2The grammes per square metre of PTFE microporous barrier is 1.0～4.0g/m
2The pore size of PTFE microporous barrier is 0.1～1.0 μ m, and porosity is 80～90%, and air penetrability is 8～14cm/s.
Above-mentioned air penetrability is what under 127Pa, measure.
Daily required in order to meet, purifying the PM2.5 mouth mask is rectangle with the cross section of replaceable overlay film filter core, and long is 105-115cm, and wide is 75-85cm.
Above-mentioned purification PM2.5 mouth mask closes and forms with the manufacture method of replaceable overlay film filter core, the first spun-bonded non-woven fabrics layer, melt-blown nonwoven layer of cloth, PTFE microporous film layers, activated carbon non-woven layer of cloth and the second spun-bonded non-woven fabrics layered suture that utilize hot melt tape edge technology that order is stacked.
In order to improve the intensity of stitching, the temperature of hot melt tape edge is 105～180 ℃, and hot melt pressure is 0.2～0.8MPa.
The not specified technology of the utility model is prior art.
The utility model overlay film filter core, utilize small-bore, the high porosity of microporous teflon membran, and it and other layers is composite, by multiple filtration and suction-operated, effectively realized intercepting the purpose that the PM2.5 particle enters human body, and the overlay film filter core is pieces of sheet, very light, Acceptable life is long, prevents the effective of PM2.5 particle, good permeability, and be replaceable use design, economize on resources, meet the characteristic of environmental requirement, be worth producing and promoting.
