Description
Technical field
This relates to a kind of ultrafine dust and removes film, belongs to environmental supplies technical field.
Background technology
Ultrafine dust is puzzled people always, wherein diameter is less than or equal to the particle of 2.5 microns, namely be the PM2.5 that we are commonly called as, can not be stopped by respiratory tract, bronchioli terminales and alveolar can be goed deep into, and deposit in alveolar, cannot discharge, affect the gas exchanges of lung, long-term suction can cause pneumoconiosis, pulmonary fibrosis, even lung cancer occurs.It is reported, " the global environment prospect 5 " of United Nations Environment Programme's announcement in 2012 points out have the premature death case of nearly 2,000,000 relevant with Particulate Pollution every year.
Haze belongs to aerosol, and aerosol is suspended in gas by solid or liquid fine particle (0.001 ~ 0.1 micron) and forms.Not only haze weather, also such ultrafine dust is there is in other lives and production, such as, the combustion gas of food and drink family scavenges, flour processing process dust, vehicle exhaust, the super cleaning shop of waste incineration, Ferrous Metallurgy or field of petrochemical industry, particularly medicine and electronic material need of production.
Have various filtration system at present, multiple absorbing material, such as active carbon, melt-blown cotton etc., industrial have electrostatic precipitator technology, and vehicle exhaust adopts " three-element catalytic technology " etc.But insufficient owing to filtering, still remain ultrafine dust and enter in air.
Summary of the invention
The object of this invention is to provide a kind of ultrafine dust and remove film, to solve the removing problem of still residual superfine particulate matter after generality process.
Implementation procedure of the present invention is as follows:
A kind of ultrafine dust removes film, and it is obtained by application of adhesive and flocculant on porous supporter.Described supporter is non-woven fabrics, cotton or other permeable fiber fabrics.Non-woven fabrics comprises spunlace non-woven cloth, heat seal non-woven fabrics, dry method of paper-making non-woven fabrics, wet nonwoven fabrics, spun-bonded non-woven fabrics, melt spraying non-woven fabrics, needle punched non-woven fabrics, loop bonding non-woven fabrics, cotton, and fiber also can do supporter.
Described adhesive is animal glue, natural plant gum, synthesis of medical glue, synthetic elastomer, synthetic thermoplastic material, synthesis thermosets, heat cure thermal conductive material and body compound adhesive, as alpha-cyano propyl group acid esters system glue, polymethyl methacrylate system glue, PVP polyvinylpyrrolidone class glue, aromatic series many methacrylic acids polyurethane series glue, polyamide, polyester, polyethylene, polyesteramide, rubber pressure sensitive glue, thermoplastic elastomer (TPE) pressure-sensitive adhesive, polyacrylate and copolymer thereof, polyurethane, polyvinyl chloride, polyvingl ether, SANWET.
Described flocculant is polyvinyl chloride, polyvinyl alcohol, polyethylene glycol, Sodium Polyacrylate, polypropylene glycol, animal glue, protein, polyacrylonitrile, polyacrylamide and graft, polymeric ferric aluminum, ferric trichloride.
The composite that also can apply sorbing material and adhesive and flocculant on porous supporter obtains, and sorbing material is active carbon, silica gel, aluminium oxide, diatomite and molecular sieve.
The dust-cleaning principle that ultrafine dust of the present invention removes polymer binder in film is novel unique, and efficiency is high; Preparation technology is simple, and cost is low; Adsorption effect naked eyes are visible, can change removing film at any time.Ultrafine dust of the present invention removes that film can be applicable to haze prevention, the combustion gas of food and drink family scavenges, super cleaning shop, flour processing, vehicle maintenance service, in paint production and use, waste incineration, Ferrous Metallurgy or petrochemical industry for removing ultrafine dust.
Detailed description of the invention
Ultrafine dust of the present invention is removed film and is obtained by application of adhesive and flocculant on porous supporter, with Breathable nonwoven or cotton or other fibers for supporter, polymer binder that is natural or synthesis, aerosol flocculant are combined into it.
The mechanism of action that this ultrafine dust removes film interception superfine particulate matter is obviously different from current material, and these polymeric binder materials have two Main Functions: promote that aerosol coagulation becomes bulky grain; Bonding superfine particulate matter.The present invention has used for reference bionic thought, and this cementation is similar to the effect of " cobweb "
.
Consider from aerosol particles coagulation angle, organic macromolecule compound directly causes micelle to be assembled and sedimentation, is called " flocculation process ".The material impelling colloidal sol that flocculation occurs is called " flocculant "." bridge formation effect " thinks that macromolecular compound is adsorbed in the surface of sol particles, is connected together by two or more micelle by bridge formation mode, due to macromolecular " spasm " effect, directly causes flocculation.What the commercially available flocculant trade mark was maximum is polyacrylamide, and other flocculants also have: polyvinyl chloride, polyvinyl alcohol, polyethylene glycol, Sodium Polyacrylate and animal glue, protein etc.
.
Super absorbent resin is the aerosol deposition agent or " flocculant " that a class performance is good.Can fluffy network structure be formed after moisture absorption, there is lower surface energy and larger specific area, as a kind of good particulate sorbing material, reduce or eliminate for aerocolloidal, the sedimentation time of smog can be made greatly to shorten.Super absorbent resin mainly contains Sodium Polyacrylate, polyacrylamide, acrylonitrile, acrylamide polysaccharide graft thing etc.The ion of organic compound has very strong coagulation ability, some inorganic matter polymeric ferric aluminums, ferric trichloride etc., also has and promotes the effect of particulate coagulation.
Adhesive is animal glue, natural plant gum, synthetic elastomer, synthetic thermoplastic material, synthesis thermosets, heat cure thermal conductive material and body compound adhesive.For requiring that the pharmaceutical manufacturer of super purification can adopt synthesis of medical glue: alpha-cyano propyl group acid esters system glue, polymethyl methacrylate system glue, PVP polyvinylpyrrolidone class glue, aromatic series many methacrylic acids polyurethane series glue, PUR and pressure sensitive adhesive.PUR mainly comprises polyamide, polyester, polyethylene and polyesteramide etc.; Pressure sensitive adhesive comprises rubber pressure sensitive glue, thermoplastic elastomer (TPE) pressure-sensitive adhesive and resin pressure sensitive adhesive.Resin pressure sensitive adhesive is main: polyacrylate, polyurethane, polyvinyl chloride, polyvingl ether etc.Take acrylate as the copolymer of main component, the composition of compound rubber and tackifying resin.

embodiment 4test effect
This experiment produces certain density cigarette at the quantitative commercially available mosquito-repellent incense of analogue means (Clear glass bottles and jars) combustion and carrys out simulated flue gas aerosol, after obtaining certain density flue gas, seal with removing film a, b, c of embodiment 1,2,3 at once, take pictures, obtain opaque photo full of smoke in bottle; Ding Daer phenomenon specific to aerosol is can be observed with light source irradiation smog.Continue to observe:
(1) can smog be observed through bottle more and more less, finally take pictures after 20-30 minute, obtain transparent picture;
(2) take off removing film to find to darken, have dense smoke taste, be bonded with small flue dust above;
(3) Ding Daer phenomenon disappears.A, b, c effect is substantially identical.
Control group does not use removing film, smog longer collapsing time about a times.
