Description
Technical field
The utility model relates to a kind of mask material, particularly a kind of anti-dust respirator filter disc.
Background technology
In productive life, the dust produced by different approaches can impact the health of people.Current, China is in modernization of industry process, and all kinds of problem of environmental pollution progressively manifests, and wherein the affect problem of dust on people ' s health is particularly outstanding, therefore becomes problem demanding prompt solution to the protection of dust.For the bulky grain thing in dust, existing guard technology generally all has good protection effect; But the fine particle in dust is because the time of staying is in an atmosphere long, fed distance is far away, and subsidiary poisonous and harmful substances (such as, heavy metal, microorganism etc.), human body bronchus can be taken directly, interference pulmonary gases exchanges, cause the diseases such as asthma, bronchitis and cardiovascular disease, thus very large on the impact of health, protection is also comparatively difficult.
In existing guard technology, people select the mode wearing mouth mask to protect the dust in air usually, but due to the fine particle penetrability in dust very strong, very easily penetrate the overcoat of mouth mask, therefore existing mouth mask product cannot realize good protection to it.
At present, the filtering material kind that the mouth mask product on market adopts is more, mainly comprises: the meltblown fibers cloth etc. of Carbon fibe felt pan, non-woven fabrics, gauze, filter paper, static electrification absorption, the overcoat of mouth mask is made up of multiple laminations of above-mentioned material usually.Wherein, the materials such as Carbon fibe felt pan, non-woven fabrics, gauze, filter paper adopt mechanical filtration, namely by intercepting layer by layer, particle are detained wherein.But these materials only can filtering bulky grain thing, the filtration result for fine particle is poor; Meanwhile, for improving filter effect, the mouth mask made with these materials often thickness is comparatively large, and can make the respiratory resistance that wearer feels very large, comfort level is poor.The work principle of filter of the meltblown fibers cloth of static electrification absorption is Electrostatic Absorption, and it has obvious suction-operated to the fine particle that particle diameter is less than 0.5 micron, and adsorption effect strengthens with the reduction of fine particle particle diameter; But the dust containing capacity of meltblown fibers cloth of static electrification absorption is limited, after the dust of various particle diameter accumulates thereon, its adsorption effect to fine particle declines very fast.
As can be seen here, above-mentioned conventional mouth mask filtering material is all undesirable to the filtration result of fine particle, can not the dust of the simultaneously better various particle diameter of filtering, and respiratory resistance is obvious, has had a strong impact on comfort.
Utility model content
All undesirable to the filtration result of fine particle for solving existing mouth mask filtering material, can not the dust of the simultaneously better various particle diameter of filtering, and respiratory resistance is obvious, affect the problems such as comfort, the utility model provides a kind of anti-dust respirator filter disc.
This anti-dust respirator filter disc is formed by multiple filtration material superimposion, comprise successively non-woven fabrics, nuclear pore membrane, static electrification absorption meltblown fibers cloth and non-woven fabrics.
The material of described nuclear pore membrane is preferably polypropylene, polyester or Merlon.
The core micropore average pore size of described nuclear pore membrane is preferably the nuclear pore membrane of 0.2-3 micron.
The core pore density of described nuclear pore membrane is preferably 10
6-10
9individual/square centimeter.
The thickness of described nuclear pore membrane is preferably 4-25 micron.
The material of the meltblown fibers cloth of described static electrification absorption is preferably polypropylene.
Nuclear pore membrane is the microporous membrane of early 1970s invention, and its microcellular structure is cylindrical vent, compared with common mouth mask filtering material, its pore size is homogeneous, has clear and definite to retain threshold value, and bearing capacity is strong, high temperature-resistant disinfected, chemistry and biological stability good, come off without particle.
In anti-dust respirator filter disc stepped construction of the present utility model, nuclear pore membrane for intercepting the part that in bulky grain thing in dust and fine particle, particle diameter is larger, by its filtering; The meltblown fibers cloth of static electrification absorption can penetrate the less part of particle diameter in fine particle that nuclear pore membrane intercepts for adsorbing; The meltblown fibers cloth that non-woven fabrics adsorbs for nuclear pore membrane and static electrification provides fixed bearing and protective effect, and can filtering part bulky grain thing.
Owing to have employed above-mentioned stepped construction, dust only deposits the part that in fine particle, particle diameter is less after nuclear pore membrane filters, and therefore adopts the meltblown fibers cloth of static electrification absorption by its filtering, and can keep good adsorption effect for a long time.Meanwhile, the venting capability of this stepped construction is good, and respiratory resistance is in use little.
In sum, anti-dust respirator filter disc of the present utility model is owing to have employed rational stepped construction and filtering mechanism, solve the problem that existing mouth mask filtering material is all undesirable to the filtration result of fine particle, can the simultaneously better dust of the various particle diameter of filtering, bacterium and virus, and respiratory resistance when reducing use, comfort level is good.
Accompanying drawing explanation
Fig. 1 anti-dust respirator filter disc of the present utility model schematic diagram.
Reference numeral: 1. non-woven fabrics, 2. nuclear pore membrane, the meltblown fibers cloth of 3. static electrification absorption, 4. non-woven fabrics.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Embodiment
As shown in Figure 1, the meltblown fibers cloth 3 that anti-dust respirator filter disc of the present utility model is adsorbed by non-woven fabrics 1, nuclear pore membrane 2, static electrification successively and non-woven fabrics 4 superimposion form, the material of described nuclear pore membrane 2 is Merlon, and the material of the meltblown fibers cloth 3 of described static electrification absorption is polypropylene.Wherein, the mass thickness of non-woven fabrics 1 and non-woven fabrics 4 is 70 grams/m, and the mass thickness of the meltblown fibers cloth 3 of static electrification absorption is 40 grams/m, and the core pore density of nuclear pore membrane 2 is 10
7individual/square centimeter, core micropore average pore size is 1 micron, and the thickness of nuclear pore membrane 2 is 12 microns.
Test to above-mentioned anti-dust respirator filter disc containing dust air with simulation, result shows this filter disc and all has good filter effect to the dust of various particle diameter.
Carry out contrast to the mouth mask finished product adopting this filter disc to make with the multiple mouth mask buied by market and try inspection on, most of examination wearer thinks that the mouth mask adopting this filter disc to make is breathed the most smooth and easy, wears for a long time and experiences well.
