Do further explanation and explanation in the face of the technical scheme of the utility model down:
A kind of mouth mask filter disc that can effectively filter PM2.5, described filter disc is a three-decker, is respectively polypropylene spunbond nonwoven skin, polypropylene fibre melt spraying non-woven fabrics intermediate layer and polypropylene spunbond nonwoven internal layer.Or be provided with the layer of active carbon layer between skin and the intermediate layer or between internal layer and the intermediate layer.
Mouth mask major part does not in the market have the effect of filtering PM2.5, and the inventor invents out a kind of filter disc that can effectively filter PM2.5 through research; This filter disc is positioned in the common mouth mask; Just can play the effect of filtering PM2.5, simultaneously cheap, the consumer is received more tangible benefits.
The filter disc that the utility model adopted is three layers or four layers of composite construction, can increase the filter effect of filter disc to pellet, and further preferred polypropylene spunbond nonwoven internal layer and the outer field grammes per square metre of polypropylene spunbond nonwoven are for being respectively 30g/m
2, the grammes per square metre in polypropylene fibre melt spraying non-woven fabrics intermediate layer is 25g/m
2, total grammes per square metre is 85g/m
2Or polypropylene spunbond nonwoven internal layer and the outer field grammes per square metre of polypropylene spunbond nonwoven are for being respectively 30g/m
2, polypropylene fibre melt spraying non-woven fabrics intermediate layer grammes per square metre is 25g/m
2, active carbon layer grammes per square metre be 40g/m
2, total grammes per square metre is 125g/m
2Active carbon layer can increase adsorption effect.This is owing to adopt the nonwoven polypropylene fabric filter disc of this thickness; Make filter disc have good particle filter efficiency; Can reach the effect of NIOSH (American National employment security health research institute) N95 type mouth mask; In the testing process to PM2.5, the novel filter disc of this use is not less than 95% to the particle filter efficiency, and can reach 99%.The filter disc of the utility model has excellent air permeability, is under the 85L/min situation at gas flow, and the inspiratory resistance of filter disc is 210～270Pa.Comfort level when the ventilative degree of mouth mask has determined to wear; The mouth mask of gas permeability difference can be in mouth mask, water smoke is formed on the surface, of long duration may multiply bacterium, and poor like the gas permeability of mouth mask; A lot of weakly old men, child and patient; All should not wear, so in the particle filter efficiency that guarantees mouth mask simultaneously, guarantee that gas permeability is only the key of product.Some cost an arm and a leg, baroque mask, face shield, and its gas permeability is poor, is inappropriate for people and uses in daily life and wear.And also there is the shortcoming of ventilative difference in the medical yarn mouth mask of 12-16 layer.
The utility model passes through the optimized choice to filter disc, thereby makes the filter disc of the utility model have filter effect and gas permeability concurrently, is the good selection of people's daily life protection PM2.5.The filter disc of the utility model can be used with the mouth mask that is designed with socket, also can be used with common mouth mask, thereby can make the common mouth mask in consumer's hand become the mouth mask that can effectively protect PM2.5.
