Abstract
The utility model relates to a composite plate type filter cloth which is characterized in that the utility model adopts a hot melt adhesive to fasten woven fabric and no-woven cloth together to form composite filter cloth. The utility model has the advantage of combining the advantages of the woven fabric and the no-woven cloth into one body, and overcomes the defects of the filter cloth requiring multilayer-overlapped use and affecting an edge sealing effect, cockamamie operation and inconvenience existing in the prior art. The dielectric material combines carelessness and compactness together. The utility model has the advantages of better filtering rate, good filtering effect and high mechanical strength. The composite filter cloth is used in the scope of 0-150 DEG.
Description
The utility model relates to a kind of plate-like product, particularly a kind of composite filtering cloth.
At present, be used for the particularly used filter medium of filter-press type filter of liquid filtering, adopt woven cloth or non-weaving cloth usually.Woven cloth mostly uses cotton textiles or synthetic fibers, and this material cost is higher, needs multilayer overlapping during use, thereby is prone to and tears wrinkle open, influences service life.Owing to the yarn of this medium formation rule arrangement, yarn closely interweaves mutually again again, and fiber lacks the possibility that forms the labyrinth system, and filter efficiency is low.Non-weaving cloth is generally bonded fabric or Nomex etc., and because of its hole is bigger, filter effect is not good, and its mechanical strength is lower simultaneously, and service life is influenced.In addition, above-mentioned two kinds of materials are because of the necessary overlapping use of multilayer, and the selvedge sealing effectiveness is bad, use also inconvenience, and it is many to consume filter cloth, the operating cost height, and economic benefit is relatively poor.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of composite board type filter cloth that to collect above-mentioned two kinds of filter cloth characteristics be one is provided.
Technical solution of the present utility model is: a kind of composite filtering cloth, comprise woven cloth or non-weaving cloth, and its special character is to adopt hotmelt that woven cloth and non-weaving cloth are tightened together, and constitutes the composite board type filter cloth.Adhesive is preferably selected polyolefin or hot-melt adhesives such as polyolefin derivative thing or improved polyalkene for use.Woven cloth is industrial poplin cloth or pure cotton fabric or blend fabric or structure other fabric more closely.Non-weaving cloth is the slim stiffening nonwoven more than two layers, and its raw material is preferably polypropylene fibre, polyamide fibre, polyester staple fiber or viscose staple fibre.
Composite filtering cloth described in the utility model has overcome existing filter cloth to be needed the overlapping use of multilayer and influences the selvedge sealing effectiveness, operate numerous rope, use inconvenient deficiency, with woven cloth and non-weaving cloth advantage molten be one, but individual layer uses, cost is low, simplifies procedures.Careless and fine and closely woven combining with cloth matter promptly has filtering rate preferably, has good filter effect again, has higher mechanical strength simultaneously.Woven cloth also plays a part to support and strengthen in as filter medium.This composite board type filter cloth can use 0～150 ℃ of scope.
Fig. 1 is a cutaway view of the present utility model.
Further specify below in conjunction with accompanying drawing.
The composite board type filter cloth that Fig. 1 provides a kind of filter press to use scribbles one deck polyolefin-based adhesive 3 between industrial poplin cloth (1) and the nonwoven (2), through the hot melt pressurization it is tightened together.
Claims (4)
1, a kind of composite board type filter cloth comprises woven cloth (1) or non-weaving cloth (2), it is characterized in that adopting hotmelt (3) that woven cloth and non-weaving cloth are tightened together, and constitutes the composite board type filter cloth.
2, composite board type filter cloth according to claim 1 is characterized in that adhesive is polyolefin or polyolefin derivative thing or improved polyalkene.
3, composite board type filter cloth according to claim 1 is characterized in that woven cloth is industrial poplin cloth or pure cotton fabric or blend fabric or structure other fabric more closely.
4, composite board type filter cloth according to claim 1 is characterized in that non-weaving cloth is the slim stiffening nonwoven more than two layers.
