Problems solved by technology

However, when the paper-plastic composite bag is recycled after use, it is found that the paper-plastic composite bag cannot be processed directly; the reason 1 is that the paper bag can be degraded but the plastic cannot be degraded; Paper bags cannot be regenerated and granulated; therefore, the paper-plastic composite material cannot

Embodiment Construction

[0009] As shown in the drawings, its structure is composed of a separation device body 2, a heating plate 3, and a heater 4; a control panel 1 is installed on the upper end of the separation device body 2; a steel heating plate 3 is installed in the separation device body 2 , an electric heater 4 is installed at the lower end of the heating plate 3 . Its working principle is as follows: First, cut the two sides of the waste paper-plastic composite material bag, and cut the bottom edge to form two plane paper-plastic composite materials. Then a stack of about 20 paper-plastic composite materials is put into the upper end of the heating plate 3 in the separation device body 2 . Then operate the control panel 1. If the paper-plastic composite material is relatively thin, control the operating temperature to about 180°C and heat it for 30 seconds. At this time, through human observation, it is found that the last piece of plastic shrinks and can be pulled out. Make the above pape...

Abstract

The invention is a kind of separation method for paper-plastic compound materials; it separates the paper and plastic in order to regenerate them. The paper of paper-plastic compound material are laid on the heating board, it is heated through the heating board; the heating temperature is from 150oC to 280 oC; the heating time is 20-50 seconds, the paper-plastic compound material is heated, thus the paper and plastic are deformed and separated. The invention can separate the paper and plastic to waste paper-plastic. The invention can solve environment protection problem.

Description

technical field [0001] The paper-plastic composite material separation method of the present invention is a method for separating waste and old composite paper-plastic materials, so that paper and plastic are separated for regeneration. Background technique [0002] At present, in the packaging of various powders and granular materials, most of them use packaging bags made of paper-plastic composite materials. This kind of packaging bag is economical and practical, with good quality, strong tensile force, small damage, rainproof and moisture-proof, easy to fold, and low cost; therefore, it is widely used in the packaging and transportation of salt, cement, flour and various chemical materials. However, when the paper-plastic composite bag is recycled after use, it is found that the paper-plastic composite bag cannot be processed directly; the reason 1 is that the paper bag can be degraded but the plastic cannot be degraded; Paper bags cannot be regenerated and granulated; t...
