Description
Technical field
The utility model relates to a kind of two-layer compound filter paper for pleated type air cleaner.
Background technology
High efficiency particle air filter (HEPA) in conventional air cleaners is generally the pleated type filter of frame-type.Wherein filter material uses the double layer material that smart nonwoven fabric (as melt spraying non-woven fabrics) and thick nonwoven fabric (as spun-bonded non-woven fabrics, immersion non-woven fabrics, wet-formed nonwoven fabric etc.) are composited.Wherein smart nonwoven layer is efficiency layer, plays the effect of filtration of particulate matters; Thick nonwoven fabric is supporting layer, plays reinforcing material deflection, keeps the effect of pleated shape.The filtration mechanism of this conventional composite filter material is Electrostatic Absorption mechanism, therefore has the feature of efficient low-resistance, can ensure the inceptive filtering effect of air purifier for particle.But, because oiliness a large amount of in air has the very strong electrostatic efficiency that disappears with the particle of carbon black class when contacting with filtering material, the filter efficiency of filtering material for particle in air purifier use procedure is caused constantly to reduce, and then affect the clean effect (Clean air delivery rate CADR) of air purifier, reduce purification life-span and the accumulation purge amount of air purifier.
Utility model content
For the problem of the filter efficiency decline that high efficiency particulate air filter filter paper electrostatic dissipation in conventional air cleaners causes, the purpose of this utility model is intended to propose a kind of two-layer compound filter paper for pleated type air cleaner.
For achieving the above object, the utility model adopts following technical scheme:
For a two-layer compound filter paper for pleated type air cleaner, it is characterized in that: comprise melt spraying non-woven fabrics filter course and glass fiber filter layer; The fiber diameter of described melt spraying non-woven fabrics filter course is 0.5-10 μm, and grammes per square metre is at 10-50g/m
2, thickness is 0.05-0.50mm; The fiber diameter of described glass fiber filter layer is 0.5-5 μm, and grammes per square metre is at 50-100g/m
2, thickness is 0.25-0.50mm.
Explanation and the further scheme of such scheme are as follows:
1., in such scheme, the grammes per square metre of described melt spraying non-woven fabrics filter course is at 10-30g/m
2, thickness is 0.10-0.30mm.
2., in such scheme, the grammes per square metre of described glass fiber filter layer is at 60-80g/m
2, thickness is 0.25-0.35mm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
A kind of two-layer compound filter paper for pleated type air cleaner that the utility model provides, wherein melt-blown nonwoven layer of cloth, filtration; Glass fiber filter layer, plays the effect of filtration and supporting layer.This duplex paper combines electro static filtering mechanism and mechanical filter mechanism, ensure that the long-lasting of filter efficiency, thus greatly improves accumulation purge amount and the purification life-span of air cleaner.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram that the utility model applies in pleated type air cleaner.
In above accompanying drawing: 1, melt-blown nonwoven layer of cloth; 2, glass fiber filter layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 1:
For a two-layer compound filter paper for pleated type air cleaner, comprise melt spraying non-woven fabrics filter course 1 and glass fiber filter layer 2; The fiber diameter of described melt spraying non-woven fabrics filter course 1 is 0.5-10 μm, and grammes per square metre is at 10-50g/m
2, thickness is 0.05-0.50mm; The fiber diameter of described glass fiber filter layer 2 is 0.5-5 μm, and grammes per square metre is at 50-100g/m
2, thickness is 0.25-0.50mm.
Wherein preferred, the grammes per square metre of described melt spraying non-woven fabrics filter course 1 is at 10-30g/m
2, thickness is 0.10-0.30mm.
Wherein preferred, the grammes per square metre of described glass fiber filter layer 2 is at 60-80g/m
2, thickness is 0.25-0.35mm.
Wherein melt spraying non-woven fabrics filter course 1 plays the effect of filter course; Glass fiber filter layer 2 plays the effect of filter course and supporting layer simultaneously.This utility model can be coated with the combination process such as compound and be prepared from by hot melt adhesive dusting compound, powder point compound, glue spraying compound or the hydrosol.
Glass fiber filter layer 2 is prepared from by wet papermaking process: cut the raw material such as thick glass fibre, synthetic fiber mixing dispersion slurrying by cotton, short for micro-for different-diameter glass.Slurry is dispersed on forming net by head box, after cylinder, fourdrinier wire or slope screen former, carry out drying and dehydrating, final formation glass fiber filter coiled material.Can select if desired to add the intensity that the adhesive such as acrylic latex, phenolic resins latex strengthens fiberglass layer in technical process.Exhibits initial filtration efficiency (0.3 micron of DOP test, test wind speed is 5.33 cels) is between 20% to 80% (preferably between 20% to 60%).Resistance (testing under 5.33 cels) is (preferably between 30 handkerchiefs to 60 handkerchiefs) between 10 handkerchiefs to 100 handkerchiefs.
