Abstract
The invention discloses three-layer composite filter cloth which comprises a first filter cloth layer, a filter membrane layer and a second filter cloth layer which are sequentially arranged from top to bottom, wherein the filter membrane layer is a PTFE filter membrane or a PU filter membrane; the first filter cloth layer and the second filter cloth layer are formed by performing warp and weft weaving on chemical fibers by virtue of a loom; the warp and weft density is not less than 5 yarns per centimeter; and the warp yarns and weft yarns are made of polypropylene fibers, polyester, acrylic, PTFE, PPS, PVDF, P84 or aramid fibers. The filter cloth layers are arranged on two sides of the filter membrane layer, so that the problem that the wear resistance is poor when the filter membrane is contacted with particles is solved. Meanwhile, compared with the filter cloth in the prior art, the particles with the size of 0.1 micron to 10 microns can be filtered and purified under the condition that the density of the filter cloth material is not changed.
Description
Technical field
The present invention relates to and make material carry out the technical field of filter cloth being separated and filtering, particularly relate to a kind of three layers of compound filter cloth and manufacture method thereof.
Background technology
Filter cloth is for allowing suspension contact with filter cloth, be less than the solid particulate matter in filter cloth aperture under the effect of the pressure through filter cloth, and the particle being more than or equal to filter cloth aperture is trapped within a kind of filter on the surface of filter cloth.
At present, if need to adapt to the filtration to different size particles material, the convention of people considers to improve count to change the size in filter cloth hole.But the aperture of filter cloth of the prior art is difficult to the size accomplishing to be less than 10 microns.Therefore filter cloth of the prior art is when collection material, and filter cloth is good not to the filter efficiency of less than 10 microns materials, cause a lot of more valuable granule materials being less than 10 microns in liquefied gas or liquid along with gas or fluid loss.Particularly other material filtering filter cloth of a kind of minimum microsize grade is badly in need of in the ultrafinepowders such as photovoltaic industry and dyestuff industry field of reclaiming.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the object of this invention is to provide a kind of three layers of compound filter cloth can accomplishing the fine particulate matter of filtration 10 micron level.
To achieve these goals, the technical solution used in the present invention is: a kind of three layers of compound filter cloth comprise the first filter layer of cloth, filter membranous layer and the second filter layer of cloth that sequentially arrange from top to bottom.
Described filter membranous layer is PTFE filter membrane or PU filter membrane.
Described first filter layer of cloth and the second filter layer of cloth all adopt chemical fibre to be formed by weaving through loom longitude and latitude, and thread count is no less than 5 pieces/centimetre.
Described warp thread is polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber.
Described weft yarn is polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber.
Described filling yarn is monofilament yarn.
Described filling yarn is folded yarn.
Described filter membranous layer is water-wet behavior.
Described filter membranous layer is hydrophobic property.
Another object of the present invention is to provide a kind of manufacture method of three layers of compound filter cloth, and it comprises the following steps:
Material is polypropylene fibre by step S1, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber fiber adopt loom longitude and latitude to be woven into the first filter layer of cloth and the second filter layer of cloth, and the density of filter cloth is no less than 5 pieces/centimetre;
Step S2, is undertaken filter cloth shaping, surperficial calendering and chemical treatment;
Step S3, adopt compounding machine by the first filter layer of cloth and the second filter layer of cloth surface the face of calendering and the two sides of filter membranous layer carry out compound respectively; In recombination process, temperature controls between 150-350 degree; The equal compound in the two sides of filter membranous layer then completes after filter layer of cloth the making of three layers of compound filter cloth.
The invention has the beneficial effects as follows: the present invention utilizes the structure being provided with filter layer of cloth on the two sides of filter membranous layer, solve the problem worn no resistance when filter membrane directly contacts with particle.Meanwhile, relative to the filter cloth of prior art, achieve under the condition not changing filter cloth material density, just can purify to the filtration of the particle of 0.1 to 10 micron of size.The present invention utilizes the structure being provided with filter layer of cloth on the two sides of filter membranous layer, achieves under the condition not changing filter cloth pore size, just can purify to the filtration of the particle of 0.1 to 10 micron of size.Meanwhile, relative to the filter cloth of prior art, the anti-wear performance that filter cloth strengthens whole compound filter cloth is all set on filter membrane two sides.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of three layers of compound filter cloth of the present invention.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the present invention is described in more detail.Should be appreciated that, these describe just exemplary, and do not really want to limit the scope of the invention.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
As shown in Figure 1, a kind of three layers of compound filter cloth comprise the first filter layer of cloth 1, filter membranous layer 2 and the second filter layer of cloth 3 that sequentially arrange from top to bottom.Described filter membranous layer 2 is PTFE filter membrane or PU filter membrane.Described first filter layer of cloth 1 and the second filter layer of cloth 3 all adopt chemical fibre to be formed by weaving through loom longitude and latitude, and thread count is no less than 5 pieces/centimetre.Described warp thread is any combination of a kind of material in polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber or two kinds and above material.Described weft yarn is any combination of a kind of material in polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber or two kinds and above material.Described filling yarn can be monofilament yarn, also can be folded yarn.Described filter membranous layer 2 can be water-wet behavior, also can be hydrophobic property.
Above-mentioned three layers of compound filter cloth can obtain by the following method:
Filter cloth adopts chemical fibre fiber characteristics to adopt loom weaving, warp thread is the organic or inorganic fibers such as polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84, aramid fiber with weft yarn, yarn feature monofilament or folded yarn, braiding can be the same monofilament of monofilament, the same folded yarn of monofilament, the same folded yarn of folded yarn.Thread count is no less than 5/cm and is made into filter cloth, carry out shaping and surperficial calendering process according to the surface smoothness in face again, again can according to final application, cloth is carried out chemical finishing again, after cloth is placed on compounding machine the polishing of cloth one side carried out compound with film, the tension force pulling force of control temperature and blowing collecting machine in recombination process, after first two layers of compound is good, again by good for compound first put time compounding machine in, by filter cloth finish side to be composite with this compound become well the PTFE film of two-layer structure or PU and temperature controlled between 150-350 degree, the speed of service controls between 3-20 rice, suitable tension force and pulling force.Warp thread and weft yarn can be single material or more than two kinds and two kinds material mixed textiles.Filter membrane material is PTEE or PU, and membrane material can select water-wet behavior, also can select hydrophobic property.
