Abstract
The invention discloses ceiling filtration cotton. The cotton comprises a fiber layer and a finely-knitted web layer, wherein the fiber layer and the finely-knitted web layer are adhered together; the density of the fiber layer increases gradually from the side away from the finely-knitted web layer to the side near to the finely-knitted web layer. Through adopting the method, the ceiling filtration cotton provided by the invention can filter out dust particles of which diameters are larger than or equal to 5 microns, can resist a temperature reaching 120 DEG C, and is stable in filtration performance and long in service life.
Description
Technical field
The present invention relates to a kind of air filting material.
Background technology
Ceiling cotton has another name called medium air filtration cotton, and main filtering object is the dust that diameter is more than or equal to 5 μ m, belongs to thick dirt and filters.On the products such as air-conditioning, train, be applicable to using.For temperature and humidity, there is tolerance.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of ceiling filter cotton, and this filter cotton can filter the dust that diameter is more than or equal to 5 μ m, and heatproof reaches 120 ℃, and strainability is stable, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of ceiling filter cotton is provided, comprise: fibrage and fine works stratum reticulare, described fibrage and fine works stratum reticulare are glued together, and described fibrolaminar density increases gradually from a side of the laterally closer described fine works stratum reticulare away from described fine works stratum reticulare.
In a preferred embodiment of the present invention, described fibrage adopts synthetic fibers to make.
In a preferred embodiment of the present invention, described fine works stratum reticulare adopts glass fibre to be made into latticed.
In a preferred embodiment of the present invention, described fibrolaminar thickness is 3-5mm.
In a preferred embodiment of the present invention, the thickness of described fine works stratum reticulare is 0.5-1mm.
The invention has the beneficial effects as follows: ceiling filter cotton of the present invention can filter the dust that diameter is more than or equal to 5 μ m, heatproof reaches 120 ℃, and strainability is stable, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of ceiling filter cotton of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, fine works stratum reticulare, 2, fibrage.
The specific embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of ceiling filter cotton, comprises fibrage 2 and fine works stratum reticulare 1, and described fibrage 2 and fine works stratum reticulare 1 are glued together, and the density of described fibrage 2 increases gradually from a side of the laterally closer described fine works stratum reticulare 1 away from described fine works stratum reticulare 1.
Preferably, described fibrage 2 adopts synthetic fibers to make.
Preferably, to adopt glass fibre to be made into latticed for described fine works stratum reticulare 1.
Preferably, the thickness of described fibrage 2 is 3-5mm.
Preferably, the thickness of described fine works stratum reticulare 1 is 0.5-1mm.
The beneficial effect of ceiling filter cotton of the present invention is:
Ceiling filter cotton of the present invention can filter the dust that diameter is more than or equal to 5 μ m, and heatproof reaches 120 ℃, and strainability is stable, long service life.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
