Abstract

The utility model discloses monofilament filter cloth for fine chemical engineering and belongs to the technical field of filter cloth for chemical industry. The monofilament filter cloth is woven of warp yarns and weft yarns, and is characterized in that the warp yarns and weft yarns are monofilaments; the warp yarns and weft yarns are made of polypropylene fibers; the polypropylene fiber monofilament of the warp yarns has the diameter phi of 0.18; the polypropylene fiber monofilament of the weft yarns has the diameter phi of 0.2; the product has the net weight of 372.4g through cleaning treatment after weaving; the warp yarns and weft yarns have dual-warp dual-weft four-section tissue; the warp floating line is long, the cloth surface is smooth, and high-temperature setting and high-temperature calendering are adopted during later-stage manufacturing, so that the dimensional stability of the cloth is guaranteed; the size change avoided due to the action of the external force in the using process, the cloth surface style is met, the cloth surface is tender and smooth, materials with fine particles can be intercepted efficiently, and the optimal filtering effect is achieved.

Description

Fine chemistry industry monofilament filter cloth

Technical field

The utility model relates to fine chemistry industry monofilament filter cloth, belongs to chemical industry filter cloth technical field.

Background technology

When China's fine chemistry industry industry was carried out Separation of Solid and Liquid to suspension, great majority used multifilament braiding filter cloth to separate with non-woven mat.In use, suspension contacts with filter cloth, solid particle less than the filter cloth aperture under the effect of pressure passes filter cloth, be trapped within surface formation one deck filter cake of filter cloth more than or equal to the particle in filter cloth aperture, then the filter cake by progressive additive continues trapped particles, thereby realizes Separation of Solid and Liquid.But in use there is following problem: l, when material viscosity surpasses certain value, is easy to stop up; 2, bacterium is easy to grow; 3, lack service life, power of regeneration is poor; 4, filter cake and filter cloth stripping performance are poor, and general woven filter cloth can not filter the bigger material of viscosity, cause difficulty for the bigger material of filtration viscosity, and efficient is low, the cost height.Just brought into use monofilament filter cloth to carry out Separation of Solid and Liquid in the world since the nineties, work efficiency obviously improves.Yet because the import monofilament filter cloth is expensive, for smaller enterprise, cost is higher, and generally uses diameter to do parallel as the polypropylene filament of ∮ 0.25 in the filter cloth weaving process, and woven like this finished product is far longer than design objective, uses limited.

Summary of the invention

In view of the defective that prior art exists, the purpose of this utility model provides a kind of fine chemistry industry monofilament filter cloth that has good filter effect and increase the service life.

For achieving the above object, the technical solution that the utility model adopts is: fine chemistry industry monofilament filter cloth, weaved by warp and parallel and to form, be characterised in that warp and parallel are monofilament, and warp and parallel all adopt the polypropylene fibre composition, the polypropylene filament diameter of described warp is ∮ 0.18, parallel polypropylene filament diameter is ∮ 0.2, after weaving, the clean processing, the product net weight is 372.4g; Described warp and parallel adopt 4 pieces of satin tissues of double ends double weft, through floating long line length, cloth cover is smooth, adopt high-temperature shaping and high temperature calendering during post-production, make the dimensional stability of cloth be guaranteed, the variation on the size in use can not take place because of the effect of external force, and satisfy cloth style, cloth cover is smoothly fine and smooth, can efficiently hold back the small material of particle, reaches splendid filter effect.

After adopting such scheme, compared with prior art have following beneficial effect: this product is through close big, and the filtering accuracy height belongs to high accuracy monofilament filter cloth, is the product of the ultra-fine material of rare filtration in the monofilament product.Product adopts 4 pieces of satin tissues of double ends double weft, and the benefit of this kind tissue is that cloth cover is smooth through floating long line length, be conducive to peeling off of filter cake, it is residual that material is not had in cloth, and bacterium can not grow in cloth, reduce the wearing and tearing of asking of material and cloth, prolong the service life of filter cloth.Adopt the technology of high-temperature shaping and high temperature calendering during the filter cloth post-production.High-temperature shaping makes the dimensionally stable type of cloth be guaranteed, and the variation on the size in use can not take place because of the effect of external force.The high temperature calendering is met cloth style, and level and smooth fine and smooth cloth cover can efficiently be held back the small material of particle, reaches splendid filter effect.
