Problems solved by technology

[0002] At present, soft PVC wastes containing fabric linings, such as waste raincoats, waste rubber shoes, waste sunshade cloth and scraps produced in the production of raincoats, rubber shoes or sunshade cloth, because there is a layer of fiber fabric mixed in PVC, there is currently no effective way to remove them. To fully recycle the PVC, it can only be discarded or landfilled. Its PVC cannot be decomposed in nature for a short time, causing pollution to the environment, and it is also a waste of PVC raw materials.

example 1

[0013] Pre-crushing the waste raincoats and waste sunshade cloth pieces containing soft PVC in the fabric lining through a pulverizer, so that the particle diameter of the pulverized PVC waste particles is 40-50mm;

[0014] Clean the pre-crushed PVC waste particles. After cleaning, wait for the particles to dry and then finely pulverize the PVC waste particles through a pulverizer, so that the particle size of the pulverized PVC waste particles is 3-5mm; the finely pulverized PVC The waste particles are input into the cyclone separation device, and then the cyclone separation device is input into the vibrating sieve for sieving, so that most of the fabric fiber wadding separated from the PVC waste generated in the fine crushing process is removed from the PVC waste particles;

[0015] The above sieved PVC waste particles are then finely pulverized by a pulverizer, and the particle size of the pulverized PVC waste particles is 1-3mm; the finely pulverized PVC waste particles are...

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

1. Technical field [0001] The invention relates to a production process for recycling soft PVC, in particular to a production process for recycling soft PVC with fabric lining. 2. Background technology [0002] At present, soft PVC wastes containing fabric linings, such as waste raincoats, waste rubber shoes, waste sunshade cloth and scraps produced in the production of raincoats, rubber shoes or sunshade cloth, because there is a layer of fiber fabric mixed in PVC, there is currently no effective way to remove them. To fully recycle the PVC, it can only be discarded or landfilled, and its PVC cannot be decomposed in nature for a short period of time, which pollutes the environment and is also a waste of PVC raw materials. 3. Contents of the invention [0003] For above-mentioned shortcoming, the object of the present invention is to provide a kind of production process that can not pollute environment and recycle the soft PVC that contains fabric lining and reuse PVC raw ...
