Description
Technical Field
The utility model relates to the technical field of articles for daily use, especially, relate to a gauze mask filter core.
Background
At present, the filter material variety that gauze mask product on the market adopted is more, mainly includes: carbon fiber felt pad, nonwoven fabric, gauze, filter paper, melt-blown fiber cloth with electrostatic adsorption, etc., and the protective layer of the mask is usually made of
A plurality of laminated layers of the above materials. Wherein, materials such as carbon fiber felt pad, non-woven fabrics, gauze, filter paper adopt mechanical type filtration, make the particulate matter retain wherein through layer upon layer separation promptly. However, these materials can only filter large particles, and have poor filtering effect on fine particles; meanwhile, in order to improve the filtering effect, the mask made of the materials is often large in thickness, so that a wearer can feel great breathing resistance, and the comfort level is poor. The filtering principle of the melt-blown fiber cloth with electrostatic adsorption is electrostatic adsorption, which has obvious adsorption effect on fine particles with the particle size smaller than 0.5 micron, and the adsorption effect is enhanced along with the reduction of the particle size of the fine particles, however, the dust holding capacity of the melt-blown cloth with electrostatic adsorption is limited, and the adsorption effect on the fine particles is reduced quickly after dust with various particle sizes is accumulated on the melt-blown cloth.
Therefore, the common mask filter material has an unsatisfactory filtering effect on fine particles, can not filter dust with various particle sizes, has obvious respiratory resistance and seriously influences the use comfort.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the existing mask is poor in filtering fine particles and bacteria, and the protection effect is poor, and provides a simple structure, and the mask filter element is breathable and can effectively filter fine particles and bacteria.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme:
a mask filter element comprises a combined cover body formed by five layers of hot pressing from outside to inside, and is characterized in that the five layers of combination are respectively as follows: the polypropylene fiber non-woven fabric outer layer, the second polypropylene fiber non-woven fabric layer, the third polyurethane non-woven fabric layer, the fourth E-PTFE nano film layer, the fifth polyurethane non-woven fabric layer and the polypropylene fiber non-woven fabric inner layer; the second layer of polypropylene non-woven fabric, the third layer of polyurethane non-woven fabric, the fourth layer of E-PTFE nano film and the fifth layer of polyurethane non-woven fabric are sequentially overlapped and hot-pressed to form, and the outer layer of the polypropylene non-woven fabric and the inner layer of the polypropylene non-woven fabric are welded with other layers through ultrasonic edge lines to form an integrated structure.
The length of the mask filter element is 12.5cm +/-1 cm, and the width of the mask filter element is 8cm +/-1 cm.
The effectiveness of this technical scheme gauze mask filter core mainly derives from two parts, the combination of the effective functional layer of multilayer, secondly the line ball formula structure as an organic whole.
The adopted polypropylene non-woven fabrics and polyurethane non-woven fabrics have simple manufacturing process flow, high yield and no toxicity or harm to human bodies, so the cost is low and the popularization is wide; and the nonwoven fabric has excellent properties such as strength, flexibility, uniformity, comfort, moisture absorption and the like.
The core filter layer is formed by sequentially overlapping a second layer of polypropylene non-woven fabric, a third layer of polyurethane non-woven fabric, a fourth layer of E-PTFE nano film and a fifth layer of polyurethane non-woven fabric in a hot-press mode. The fourth layer of E-PTFE nano film is a material with wide application, and a core filter layer prepared by compounding and connecting the fourth layer of E-PTFE nano film with non-woven fabrics has air permeability and can effectively block ultrafine dust particles, smoke particles, floating dust, sand storm and raised sand and various other harmful pollutants and bacteria in the air, and the protection effect of the fourth layer of E-PTFE nano film cannot be rapidly attenuated. The aeration resistance is less than or equal to 150Pa, the filtration rate of salt particles reaches 99 percent, and the filtration rate of bacteria with the average particle diameter of 3.0 mu m reaches 99 percent.
Utilize ultrasonic wave technology, the line ball synthesis integral type circular arc structure accords with human face structure, can effectively block the extremely fine dust particle in the air, soot, floating dust, sand storm raise sand and various other harmful pollutants and get into the respiratory track to the protection people avoid the injury of fine particle dust and the infringement of bacterium.
The utility model has the advantages that: light and breathable, and effectively prevents ultrafine dust particles, smoke particles, floating dust, sand storm and sand and various other harmful pollutants and bacteria in the air.
