For solving the technological means of problem
In order to solve the problem of the above-mentioned prior art, air cleaning filter of the invention and possesses air purification use The air purifier of filter has following composition.
Technical scheme 1 record air cleaning filter possess fiber assembly, conformal component, recess and Epidermis；The fiber assembly is formed as non-woven fabric-like by the fiber of aluminum or aluminium alloy；The conformal component it is made of aluminum or It is made of aluminium alloy and there are multiple hole portions, capped two planes for being arranged on above-mentioned fiber assembly；It is right that the recess passes through The surface of the above-mentioned fiber of the upstream side of at least the above fiber assembly carries out roughened formed；The epidermis is to be formed on The alumina layer or aqua oxidation aluminium lamination of the outer surface of above-mentioned fiber assembly and above-mentioned conformal component.
According to this composition, following such effect is obtained.
(1) by being formed as the fiber assembly of non-woven fabric-like with the fiber by aluminum or aluminium alloy, with glass fibers Dimension, paper are negatively charged compared to being easier to, and the particulate such as PM2.5 of positively charged is strongly attracted and is captured in atmosphere, so, can Particulate is trapped without allowing particulate to flee from, can positively keep the particulate being captured, the efficiency of the trapping of particulate, certainty are excellent More.
(2) non-woven fabric-like is formed by fiber assembly, fiber intricately kinks, although thin particulate is easily hung Firmly, can the really and expeditiously object to be processed matter such as trap debris, particulate, so, total thickness can be made thinning, easily sought light Quantify, resource-saving, operability are superior.
(3) it is capped to be arranged at the two of fiber assembly since there are multiple hole portions with conformal component, the conformal component A plane, so, it can prevent deforming, being damaged for fiber assembly, shape stability, operability are superior, also, can be by conformal structure Part is adjusted the thickness of fiber assembly, and property is superior freely for design.
(4) occasion being made of metal in fiber assembly and conformal component, using crimping, welding, sintering the methods of Firmly fix fiber assembly and conformal component, superior durability, it is not necessary to the shape holding members such as frame are separately equipped with, can Simplify and form, batch generation property is superior.
(5) surface by the fiber with the upstream side (air inflow side) for making at least fiber assembly is roughened come shape Into recess, can make fiber assembly fiber surface area increase, so, it is possible to increase the contact surface with the particulate in air Product, particulate are liable to stick on the surface of the fiber of fiber assembly, and the efficiency of the trapping of particulate, certainty are superior.
(6) since fiber assembly by the fiber of aluminum or aluminium alloy is formed as non-woven fabric-like, so, can be to being adsorbed Cleaned, can be removed it by dust catcher attraction, maintainability, environmental protection property are superior in the process object material of fiber.

(g) voidage as fiber assembly, preferably 50~90%.As voidage becomes smaller than 50%, can lead to The quantitative change for the air crossed is few, and there are blocking to become incidental tendency, and with becoming bigger than 90%, mesh is thicker, becomes not Particulate can be trapped, there is the tendency that trapping performance becomes to be easily reduced, it is all undesirable.
(h) thickness as air cleaning filter, preferably 1~4mm.With the thickness of air cleaning filter Become thinner than 1mm, the ratio of fiber assembly tails off, the object to be processed qualitative change in air easily by becoming unable to catch Collect particulate, there is the tendency that trapping performance becomes to be easily reduced, as thickness becomes thicker than 4mm, the amount increase of fiber assembly, Can be few by the quantitative change of the air of fiber assembly, there are blocking to become incidental tendency, all undesirable.By making sky The thickness of gas purifying filter is as thin as 1~4mm, can carry out Bending Processing etc., and processability is superior, and the free degree of design is high, institute With, can be corresponding with variform various equipment, light weight, operability, versatility are superior.
(i) when fiber assembly and conformal component are all made of aluminum or when being made of aluminium alloy, hydration is formed on the surface The layer (envelope) of aluminium oxide (hydrous oxide of aluminium), so, it is more satisfactory.
(j) aluminium by more than about 90 DEG C of hot water (or vapor), being become hot water, water steaming by hydrated alumina The passive state that the contact surface of gas and aluminium is reacted and formed.Therefore, by setting water on the surface of fiber assembly and conformal component Close alumina layer, even in bactericidal metal be mixed into it is sprayed in occasion, aluminium also do not contact with dissimilar metal, moisture it is attached Electric current caused by also does not occur, so, it can prevent the galvanic corrosion (electrochemical corrosion) of corpus fibrosum, conformal component.
(k) thickness as aqua oxidation aluminium lamination, preferably 0.2~2 μm.As the thickness of aqua oxidation aluminium lamination becomes to compare It is 0.2 μm thin, it becomes difficult to form aqua oxidation aluminium lamination, also, the intensity of epidermis is difficult to improve, and is closely connect with sprayed Touching property reduces, there are the tendency that corrosion resistance, durability become to be easily reduced, with becoming than 2 μ m-thicks, aqua oxidation aluminium lamination Formed it is time consuming, it is all undesirable there are the tendency that productivity becomes to be easily reduced.
(l) epidermis as the outer surface for being formed at fiber assembly and conformal component, although as long as fibre can be protected The epidermis of aggregate and conformal component is tieed up, but can be compatibly using hard, corrosion resistance, the superior table of wear resistance Cortex.
(m) by the occasion of the sprayed outer surface for being formed at epidermis, as epidermis, as long as spraying plating material can be made The close contact of material improves, the epidermis that corrosion resistance is superior, melting point is high, then is not particularly limited.
In addition, as fiber assembly and conformal component be made of aluminum or epidermis of the occasion made of aluminium alloy, can Include aluminium oxide (Japanese：ア Le マ イ ト), hydrated alumina (Japanese：ベ ー マ イ ト) etc..Wherein, in hydrated alumina Occasion, due to can independently form the overall epidermis without spot with the shape of air cleaning filter, so, it is more satisfactory.
As long as (n) conformal component of the conformal component with multiple hole portions, the shape that fiber assembly can be kept, material Matter is not particularly limited, and can be metal or synthetic resin.In the occasion that conformal component is made of metal, although as long as It is dictyosome or porous metallic plate, is then not particularly limited, but metal lath, perforated metal, woven wire etc. can be compatibly Use.Wherein, because without the crooked of mesh, bonding part is integrally formed metal lath, so, robustness is superior, air For Flowing Hard to be blocked, the stability of shape is also superior.
In addition, the occasion being made of metal in conformal component, material are not particularly limited, can be used iron, copper, silver, gold, aluminium, Nickel, stainless steel, tungsten, molybdenum etc..
(o) percent opening of conformal component can compatibly use 50~90% percent opening.With the percent opening of conformal component Become smaller than 50%, exposing for fiber assembly diminishes, and the unit interval can be few by the quantitative change of the air of fiber assembly, exists Blocking becomes incidental tendency, and with becoming bigger than 90%, the structural strength of conformal component dies down, and exists and is led by external force etc. Breakage of cause etc. becomes incidental tendency, all undesirable.
(p) the mesh opening area of 1 hole portion of conformal component can compatibly use 0.5~500mm2Mesh opening face Product.As the mesh opening area of hole portion becomes to compare 0.5mm2Small, mesh attenuates, and air is become difficult to by the way that there are easy hair The raw tendency blocked, with becoming to compare 500mm2Greatly, mesh is thicker, becomes unable to trap particulate, and there are trapping performance Become the tendency being easily reduced, it is all undesirable.
(q) thickness as conformal component, can compatibly use the thickness of 0.3~1mm.Become with the thickness of conformal component Must be thinner than 0.3mm, bending strength deficiency, in the presence of becoming easily disrumpent feelings tendency during manufacture, with becoming thicker than 1mm, fiber collection Zoarium tails off relative to the ratio of the thickness of air cleaning filter entirety, exist cannot fully obtain that air passes through when The tendency of the separation function of the process object material of time, it is all undesirable.
The invention that technical solution 2 is recorded is that in the air cleaning filter that technical solution 1 is recorded, have following structure Into, i.e. possess the sprayed of the outer surface that is formed at above-mentioned epidermis, this is sprayed to include the gold with photocatalyst function Belong to compound.
According to this composition, in addition to the effect of technical solution 1, following such effect is also obtained.
(1) sprayed due to being formed in the outer surface of fiber assembly and the epidermis of conformal component, this is sprayed Comprising the metallic compound with photocatalyst function, so, the close contact of the metallic compound obtained by spraying plating is high, spray Plate stripping of envelope etc. to be difficult to happen, durability, the quality stability of product are superior.
(2) epidermis is utilized, fiber assembly and conformal component is not directly contacted with sprayed, so, if table Cortex is passive state, then the fiber assembly as caused by being attached to the moisture on air cleaning filter surface, conformal structure do not occur The galvanic corrosion (electrochemical corrosion) of part, corrosion resistance is superior, and can make to kill in bactericidal metals such as sprayed middle combined silver, copper Bacterium property improves.
(3) since the surface of the fiber formed with epidermis is roughened, concavo-convex, institute is formed on the outer surface of epidermis With using anchoring effect, depositing materials are easily deep into the recess of epidermis, and sprayed compactness, close contact property are excellent More.
(4) due to possessing the sprayed of the outer surface for the epidermis for being formed at fiber assembly and conformal component, the spray Plate envelope and include the metallic compound with photocatalyst function, so, contacted for the surface with air cleaning filter Virus, the bactericidal properties of bacterium are superior.
