Abstract
The utility model discloses a flame-retardant washable nano-photocatalyst-activated carbon fiber membrane-coated filtering material. The main point of the technical scheme of the utility model is that the flame-retardant washable nano-photocatalyst-activated carbon fiber membrane-coated filtering material comprises a flame-retardant washable nano-photocatalyst-activated carbon fiber non-woven fabric, wherein the flame-retardant washable nano-photocatalyst-activated carbon fiber non-woven fabric is formed by soaking in a flame-retardant glue solution, rolling by dual rollers, drying, spraying the flame-retardant glue solution, drying and flattening. The surface of the flame-retardant washable nano-photocatalyst-activated carbon fiber non-woven fabric is coated with a layer of polytef membrane. The polytef membrane has the characteristics of microporosity, air permeability and hydrophobic nature, the surface of the membrane is smooth, the frictional coefficient is very low, the sticky dust stripping property is good, no dust is accumulated easily, the micropore diameter of the polytef membrane can be chosen according to the applicable filtering and purifying occasion, and then the purpose of preliminary filtering is fulfilled.
Description
Technical field
The utility model relates to a kind of anti-flaming washable filter material, is specifically related to a kind of anti-flaming washable nano photo-catalytic-NACF coated filter material.
Background technology
In daily life, as room, kitchen, lavatory and public place etc., due to people's life activity frequently, all can inevitably to surrounding environment, bring certain pollution.According to related data investigation, these gases such as volatile solvent, oil smoke and sweat acid smell that airborne pollutant mainly contains hydrogen sulfide, sulfur dioxide, carbon monoxide, ammonia, finishing material mostly exist with the molecule of gas phase.In addition, the stink that people's sense of smell can be differentiated, is mainly the little molecular organic compound that contains ammonia nitrogen and sulfydryl sulfide (hydrogen sulfide, mercaptan, thioether, isovaleric acid and amido), and the diameter of these gas molecules is all less than 0.3 μ m conventionally.
Nano photocatalyst-active carbon fiber composite filter medium, be mainly used in household electrical appliance filter element, it is a kind of high dust catching rate that has, gel powder with high adsorptive, antibiotic, deodorizing, the functional air filtering medium of the characteristics such as water-fastness and long-life, can make the organic molecule aerosol that conventional efficient filter layer cannot trap be adsorbed very rapidly by the activated carbon granule of nano carbon fiber, because nano photo-catalytic-activated carbon granule is dispersed in the surface of carrier fibre, carrier macromolecule plays the effect of fixed bonding nano particle, have water-fastness, do not fall the characteristic of charcoal particle.In addition, in actual use procedure, nano active charcoal layer is placed in the outlet air surface of filter element conventionally, and the Wave-shaped structural that its pleating material provides can facilitate for uviol lamp fully irradiates active carbon, is more conducive to the regeneration of active carbon layer.
The current fire-retardant filtering material that we use is due to water-fastness, needs the filtering material that more renews after dust containing capacity reaches capacity, and so both increased the spending of enterprise, again environment caused to pollution simultaneously.Poly tetrafluoroethylene has very high peel strength, and cohesive is very excellent, makes this poly tetrafluoroethylene can not depart from easily viscose non-woven material layer.Therefore, be necessary a kind of anti-flaming washable nano photo-catalytic-NACF coated filter material of design research and development, so both can reduce deashing frequency, filtering material is dirty and can after washing, reuse, and has also reduced the production cost of enterprise when reducing waste pollution.This material can carry out in-depth filtration to air, and this filtering material has again anti-flammability, greatly improves fireproof security.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of anti-flaming washable nano photo-catalytic-NACF coated filter material, this filtering material arresting efficiency is high, deashing is easy, good mechanical property, anti-flaming washable, and can under the effect of photocatalyst, make active carbon there is the adsorption function of regeneration.
The technical solution of the utility model is: a kind of anti-flaming washable nano photo-catalytic-NACF coated filter material, comprise anti-flaming washable nano photo-catalytic-activated carbon fiber non-woven cloth, it is characterized in that: described anti-flaming washable nano photo-catalytic-activated carbon fiber non-woven cloth is to be first soaked in fire retardant glue solution, through two roll-ins, roll, dry, spray again fire retardant glue solution, oven dry, pressing form, and this anti-flaming washable nano photo-catalytic-activated carbon fiber non-woven cloth surface is covered with one deck poly tetrafluoroethylene.
The micropore size of poly tetrafluoroethylene described in the utility model is 0.2-15 μ m, and thickness is 20-100 μ m, and porosity is more than 95%.
Anti-flaming washable nano photo-catalytic-NACF coated filter material described in the utility model is the filtering material that fiber intersection points is fixing by glue point and anti-flaming washable nano photo-catalytic-activated carbon fiber non-woven cloth surface is covered by poly tetrafluoroethylene.
The utlity model has following advantage: be 1, a kind of anti-flaming washable filter material, 2, can recycle, active carbon can be regenerated under the effect of nano photo-catalytic, again the adsorption function of activity recovery charcoal, 3, the micropore size of poly tetrafluoroethylene can be selected according to applicable filtration, purification occasion, and then realizes preliminary object of filtering, 4, coated poly tetrafluoroethylene has very high peel strength, and cohesive is very excellent, makes this filtering material can not depart from easily viscose non-woven material layer in filtration and deashing process, in addition, poly tetrafluoroethylene has microporosity, gas permeability and hydrophobicity, film surface is smooth, rubbing, it is extremely low to examine coefficient, binding dust fissility is good, be difficult for laying dust, make the big dust particle in flue gas almost all be blocked in the surface of poly tetrafluoroethylene, the dust layer forming is easily fallen clearly, realize surface filtration, big dust particle can not be penetrated into the inside of anti-flaming washable nano photo-catalytic-activated carbon fiber non-woven cloth, big dust particle does not contact with anti-flaming washable nano photo-catalytic-activated carbon fiber non-woven cloth, wearing and tearing have been reduced, reduced deashing energy consumption, greatly improved the service life of filtering material.
