Abstract

The invention relates to a method for recycling fabric liner soft PVC, which breaks PVC waste blocks into 1-3mm particles, to be screened out most fabric fiber group separated from PVC waste, then obtains PVC particles in a particle separator. The invention has the advantages that the invention can completely recycle the PVC in fabric liner soft PVC, while the PVC content can reach 99.5%, to reuse PVC and reduce pollution.

Description

The production technology that soft PVC containing woven lining reclaims
One, technical field
The present invention relates to the production technology that a kind of flexible PVC reclaims, especially relate to the production technology that a kind of soft PVC containing woven lining reclaims.
Two, background technology
Present soft PVC containing woven lining waste material, the leftover pieces that produce in the production as useless raincoat, scrap rubber footwear, useless puggaree and raincoat, rubber overshoes or puggaree, owing in PVC, be mixed with one deck fabric, also there is not effective method that this PVC is recycled fully at present, can only abandon or carry out landfill, its PVC can't short-term decompose at occurring in nature, and environment has been caused pollution, also is simultaneously the waste to the PVC raw material.
Three, summary of the invention
At above-mentioned shortcoming, the object of the present invention is to provide a kind of production technology that can environment not polluted and utilize again the soft PVC containing woven lining recovery of PVC raw material.
Technology contents of the present invention is, the production technology that a kind of soft PVC containing woven lining reclaims, and its production stage is:
(1), the useless piece material of soft PVC containing woven lining is carried out precomminution through pulverizer earlier, making the PVC waste material particle grain size after the pulverizing is 40～50mm;
(2), the PVC waste material particle after the precomminution is cleaned, after the cleaning, it is broken to treat that particle drying carries out fine powder by pulverizer with PVC waste material particle again, and making the PVC waste material particle grain size after the pulverizing is 3～5mm; PVC waste material particle input cyclone separator with fine powder after broken is sieved by cyclone separator input sieve again, most of fabric fibre of separating from the PVC waste material that produces in fine powder is broken is wadded a quilt with cotton remove from PVC waste material particle;
(3), that the PVC waste material particle after above-mentioned the sieving is carried out fine powder through pulverizer again is broken, the PVC waste material particle grain size after the pulverizing is 1～3mm; PVC waste material particle input cyclone separator with fine powder after broken is sieved by cyclone separator input sieve again, most of fabric fibre of separating from the PVC waste material that produces in fine powder is broken is wadded a quilt with cotton remove from PVC waste material particle;
(4), the PVC waste material particle after will sieving in step (3) sends into the particle separation machine, and the remaining fabric fibre wadding of separating from the PVC waste material is thoroughly separated with PVC waste material particle, promptly obtains the PVC particle of recyclable utilization.
Cyclone separator is that the pulverized particles of PVC waste material is separated with the fabric fibre wadding of pulverizing from PVC and separating in aforementioned production method, makes them not produce bonding, and the pulverized particles of being convenient to the PVC waste material is by sieve fabric fibre wadding.
The advantage that the present invention had is the PVC that can fully reclaim in the soft PVC containing woven lining, the content of PVC reaches more than the 99.5 weight % in the PVC pulverized particles that reclaims, the PVC of recovery is utilized again, significantly reduced the pollution destruction of this waste material environment.
Four, specific embodiment
Example 1:
The useless raincoat of soft PVC containing woven lining and useless sunshade cloth material are carried out precomminution through pulverizer earlier, and making the PVC waste material particle grain size after the pulverizing is 40～50mm;
PVC waste material particle after the precomminution is cleaned, and after the cleaning, it is broken to treat that particle drying carries out fine powder by pulverizer with PVC waste material particle again, and making the PVC waste material particle grain size after the pulverizing is 3～5mm; PVC waste material particle input cyclone separator with fine powder after broken is sieved by cyclone separator inputted vibration sieve again, most of fabric fibre of separating from the PVC waste material that produces in fine powder is broken is wadded a quilt with cotton remove from PVC waste material particle;
It is broken that PVC waste material particle after above-mentioned the sieving is carried out fine powder through pulverizer again, and the PVC waste material particle grain size after the pulverizing is 1～3mm; PVC waste material particle input cyclone separator with fine powder after broken is sieved by cyclone separator inputted vibration sieve again, most of fabric fibre of separating from the PVC waste material that produces in fine powder is broken is wadded a quilt with cotton remove from PVC waste material particle;
PVC waste material particle after sieving above-mentioned two is sent into the particle separation machine, and the fabric fibre wadding of separating from the PVC waste material is thoroughly separated with PVC waste material particle, obtains the PVC particle of recyclable utilization; The content of PVC reaches 99.8 weight % in the PVC pulverized particles that reclaims.
