Abstract
The invention discloses a manufacturing method of a reinforcing bar pleating filtering structure. The structure comprises a filtering bottom layer and a polyester reinforcing bar net, wherein the polyester reinforcing bar net is attached to the filtering bottom layer; and then a pleating operation is performed. As the polyester reinforcing bar net is attached to the filtering bottom layer instead of a metal structure, the cost is low; and the polyester reinforcing bar net is attached to the filtering bottom layer before the pleating operation, the processing is simple and easy, and the polyester material can be sufficiently degraded and recycled.
Description
Technical field
The present invention relates to a kind of manufacturing approach of strengthening the pleating filtration of arrangement of reinforcement.
Background technology
Strengthening the pleating filtration of arrangement of reinforcement is a kind of comparatively general construction package in the filtration, conventional filter in the market, and such as Al-alloy metal framework filtration, cost is high, and difficulty of processing is big, and material can not fully repeat to reclaim.
Summary of the invention
For overcoming the defective of prior art, the technical problem that the present invention will solve has provided the manufacturing approach of the pleating filtration of reinforcement arrangement of reinforcement that a kind of cost is low, processing is simple and easy, material can fully reclaim.
Technical scheme of the present invention is: the manufacturing approach of the pleating filtration of this reinforcement arrangement of reinforcement, this structure comprise filters bottom and polyester reinforcement network, and the polyester reinforcement network is attached to and filters on the bottom, carries out pleating operation again.
Because adopting polyester arrangement of reinforcement sheet to replace metal structure to be attached to filters on the bottom, so cost is low; And polyester arrangement of reinforcement sheet is attached to through mechanical degradation and filters on the bottom, carries out pleating operation again, can fully reclaim so process simple and easy, material.
The specific embodiment
Do further detailed description in the face of technical scheme of the present invention down.
The manufacturing approach of the pleating filtration of this reinforcement arrangement of reinforcement, this structure comprise filters bottom and polyester reinforcement network, and the polyester reinforcement network is attached to through mechanical degradation and filters on the bottom, carries out pleating operation again.The polyester reinforcement network is perhaps filtering on the bottom through pasting such as glue, perhaps is placed on regard to frictionally without jointing material simply and filters on the bottom.Optimum structure is to comprise two jacket layers; Two jacket layers are in different plane; The net that forms like this is the prior art of being known, its fusion polymer is extruded into the cylindrical net goods, the smooth then water tank of crossing after through two mutually despun moulds; Cut according to machine direction then, promptly be shaped to planar bilayer nonwoven sheet or net.
Complete filtration tissue comprises that polymeric layer with holes, net and filtration bottom are as a pleating structure simultaneously.The effect of this polymer arrangement of reinforcement layer with holes helps to keep the pleating structure of appended filtration bottom.
The specific constituent of filter bottom does not constitute any limitation in this invention.Especially, filter bottom and can use various types of materials and use structure miscellaneous, this depends on that this filters the application scenario of bottom.Filter bottom and can use textile fabric, continuous fiber, diaphragm and film.In addition, filtering bottom can be formed by laminated multi-layer, such as use multilayer revolve spunbond close with or molten blowing material, and multilayer different polymer, such as polyester, nylon etc.
Preferably, said mechanical degradation is mechanical cracking or polishing, and it is pleating that said pleating operation is to use anilox roll to carry out, and the footpath number of the polyester reinforcement network that forms is generally 2 strands-25 strands of per inch.Just need not carry out the thermosetting operation, so the polyester reinforcement network is processed by original polyester material like this.
Preferably, said polyester arrangement of reinforcement sheet adopts fusing point smaller or equal to 350 ℃ polyester material.Better, said polyester reinforcement network adopts fusing point smaller or equal to 265 ℃ polyester material.Best, said polyester reinforcement network employing fusing point is 240-265 ℃ a polyester material.
Preferably, said polyester reinforcement network adopts the polyester material processing that gathers para Toluic Acid's fourth two fat or PET.
Preferably, the footpath number that forms the polyester reinforcement network is 2 strands-15 strands of per inch more fortunately.Better, the footpath number that forms the polyester reinforcement network is 2 strands-6 strands of per inch.
Preferably, said polyester reinforcement network adopts the PET film to carry out mechanical degradation, the net footpath be 4 bursts of footpaths of per inch in one direction and 3 bursts of footpaths of per inch on another direction.Wherein, breaking of the carbon-to-carbon set of control PET film makes its cleanliness factor be reduced to 40%-50% from original 65%.Better so noncrystallinely organize hardlyer, need not heat the ability that can keep fold so possess.
The used polyester reinforcement network of the present invention is to use the non woven web of being processed by original copolymer to have the manufacture of identical non woven web with prior art.Prior art has different registration marks by U.S. moral star technology company, comprises Delnet, Naltex, Delpore and Delnet.
PETP; Possibly cause the fracture of carbon-to-carbon set in its tissue such as the mechanical degradation of PET film; Can provide a more unbodied structure to make non woven web compare with using undegradable polymeric material like this, the intensity of net is bigger and harder.Special feature is that the PET of mechanical degradation has been considered to have the initial coefficients higher than original copolymer, but lower fracture elongation.
Adopt the beneficial effect of above scheme to be:
1. alternative metals structure.
2. plastic material is reproduced utilization easily.
3. reduce the problem that reduces injury to personnel, because the edge of metal is quite sharp-pointed.
4. material structure own is more firm: also know simultaneously and can use polymer, the mesh plate is made with the former para Toluic Acid's of gathering fourth two fat PET, works to strengthen pleating filtration bottom.But these strengthen sheet material, under original state, have very much a pliability, originally form be highly susceptible to bending, be unfavorable for forming the fold state that effectively keeps on the bottom so that attached reinforcement sheet material is played booster action filtering.Therefore, when pleating filtration uses PET to strengthen sheet material, to use glue on the footpath of PBT sheet material (line), to smear at first; Adhere to this sheet material then and filter bottom to the plane; The heated lamination structure when structure is in lamination, forms pleating laminar structure with the lamination tissue through pleating roller.Subsequently, rely on the cooling of pleating structure, the pleating structure of the filtration bottom that the thermal finalization of PBT mesh sheet material helps to keep appended on pleating structure.In many cases, PBT mesh sheet material need be applied to the tow sides of filtering substrate, heating and pleating before enough pleating laminations of behind thermoset forming, stablizing are provided.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs to the protection domain of technical scheme of the present invention to any simple modification, equivalent variations and modification that above embodiment did.
