Abstract
The invention discloses an air filter paper which is suitable for usage under sandstorm and haze environment, the air filter paper comprises an upper layer fibrous layer and a lower layer fibrous layer, a resin layer is coated on the upper side of the upper layer of the fibrous layer, the upper layer fibrous layer is mercerized wooden fiber with 65-85g/cm<2>, and the lower layer fibrous layer is broad leaf wooden fiber with 40-60g/cm<2>. The air filter paper has high filtration accuracy and can ensure the filtering efficiency of the filter paper.
Description
Technical field
The present invention relates to filter paper technical field, be specifically related to a kind of air paper being applicable under dust storm area and haze environment.
Background technology
Traditional air paper structure is single xylon layer, surface-coated resin bed.This class air paper, under the environment of large dust storm and haze, because fiber is single, makes interfibrous void ratio more even.Dust easily stops up space, thereby causes porosity to reduce, and dust containing capacity also extremely declines, and filter effect is obviously on the low side.
Therefore, we need to have the air paper compared with the long life under a kind of adverse circumstances again.
Summary of the invention
The object of the invention is for a kind of air paper that can use under the adverse circumstances such as large dust storm and haze is for a long time provided.
In order to achieve the above object, the invention provides following technical scheme: a kind of air paper, comprise top fiber layer and lower floor's fibrage, described top fiber layer upside scribbles resin bed, described lower floor fibrage downside scribbles resin bed, described top fiber layer is that the mercerization xylon of 65-85 gram/cm forms, and described lower floor fibrage is that the broad-leaved wood fiber of 40-60 gram/cm forms.
Described top fiber layer and lower floor's fibrage through directly compound, then dried and are formed filter paper blank after processing through drawing water respectively, and blank surface obtains described air paper after resin-coated.
In order to realize the structure of above-mentioned air paper, need to adopt following manufacture craft: by wet different stacked being added together of xylon of fibre length in two up and down, extract its moisture out by vacuumizing, two-layer formation is pricked mutually and glue for one deck structure, after drying, form filter paper blank, be that two fibre layers is in the time vacuumizing, fiber head with the broad-leaved wood fiber layer of air-flow direction penetrates in pin mercerization wood fibre layer, make thus two fibre layers mutually prick and stick together, make broad-leaved wood fiber form the wooden fibrage of lower floor's fibrage and upper strata between fiber holes be not destroyed, therefore relatively improve its porosity and held dirt rate, extend its service life
Beneficial effect of the present invention: because top fiber layer adopts the mercerization fiber of fiber in long stapled mercerization fiber and part, its fibrolaminar aperture is larger, and porosity is large, makes top fiber layer have good dust absorbing ability; And lower floor's fibrage adopts the broad-leaved wood fiber of staple fibre, its fibrolaminar aperture is less, and porosity is little, makes the fibrolaminar filtration effect of lower floor better, and filtering accuracy is high.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of air paper of the present invention.
1, top fiber layer; 2, lower floor's fibrage; 3, resin bed.
Detailed description of the invention
Below in conjunction with accompanying drawing, the air paper described in the present embodiment is further described.
As shown in fig. 1, the air paper of the present embodiment, comprise top fiber layer 1 and lower floor's fibrage 2, described top fiber layer 1 upside scribbles resin bed 3, described lower floor fibrage 2 downsides scribble resin bed 3, described top fiber layer 1 is that the mercerization xylon of 65-85 gram/cm forms, and described lower floor fibrage 2 is that the broad-leaved wood fiber of 40-60 gram/cm forms.Described top fiber layer 1 and lower floor's fibrage 2 through directly compound, then dried and are formed filter paper blank after processing through drawing water respectively, and blank surface obtains described air paper after resin-coated.
In the present embodiment, being filtered fluid media (medium) flows into from the top fiber layer 1 of thick and porosity gap, flow out from lower floor's fibrage 2 of fine and closely woven hole, impurity is mainly intercepted in the macrovoid of top fiber layer 1, because top fiber layer 1 interstitial space is large, there is huge dust capaciting ability, thereby greatly extend filtration members service life, and filtration resistance is low, and the tight and tiny hole of lower floor's fibrage 2 is further tackled less in the rear fluid media (medium) of top fiber layer 1 filtration and minute impurities particulate.Effectively ensure filtering accuracy, given full play to each fibrolaminar combination property.
Top fiber layer of the present invention, except adopting mercerization pulpwood, also can adopt single needle pine slurry or the composite material of needle pine slurry and mercerization wood pulp.Concrete material is changeable, does not do concrete restriction.
Claims (2)
1. an air paper, it is characterized in that: comprise top fiber layer and lower floor's fibrage, described top fiber layer upside scribbles resin bed, described lower floor fibrage downside scribbles resin bed, described top fiber layer is that the mercerization xylon of 65-85 gram/cm forms, and described lower floor fibrage is that the broad-leaved wood fiber of 40-60 gram/cm forms.
2. air paper according to claim 1, it is characterized in that: after described top fiber layer and lower floor's fibrage are processed through drawing water respectively, through directly compound, then to dry and form filter paper blank, blank surface obtains described air paper after resin-coated.
