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
Composite paper-plastic material separation method of the present invention is that the waste and old paper material that is combined with each other is separated, and paper and plastics are separated so that the method for regenerating respectively.
Background technology
At present, most of packaging bag of adopting composite paper-plastic material to make in the packing of various powder, grain material.This packaging bag is economical and practical, and quality is good, pulling force is strong, breakage is little, rainproof protection against the tide, folding convenient, and cost is low; So in a large amount of packed and transported that is applied to salt, cement, flour and various chemical materials.But when after the composite paper-plastic material bag uses, recycling, find that but this composite paper-plastic material bag can not directly handle; Its reason 1 is that paper bag can be degraded and plastics can not be degraded; Its reason 2 is that plastics can regeneration and granulation and paper bag can not regeneration and granulation; So the composite that this paper is combined with each other can't directly be handled, paper must separate and could handle respectively; And also do not have this separation method at present, be very necessary so develop a kind of separation method to overcome compound this problem that can't separate of paper according to the existing in prior technology problem.
Summary of the invention
In view of the existing in prior technology problem, the objective of the invention is to develop a kind of method that paper in the composite paper-plastic material bag is separated with plastics.
Composite paper-plastic material separation method of the present invention is that the waste and old paper material that is combined with each other is separated, and paper and plastics are separated so that the processing method of regenerating respectively.
A kind of composite paper-plastic material of the present invention is on the paper placing flat heating plate with composite paper-plastic material, to heat by heating plate; Its heating-up temperature is between 150 ℃～280 ℃; Between 20 seconds～50 seconds heat time heating time, the plastic shrink distortion on the composite paper-plastic material is separated with paper by heating.The composite paper-plastic material of the separation method of composite paper-plastic material of the present invention is composited by paper and plastics, and paper is wood pulp paper or straw paper; Plastics are poly-third ethene or polyethylene.
Application of the present invention can separate the waste and old paper pocket that can't handle in the past, thereby waste paper can be regenerated.Can utilize pulping and paper-making; The renewable granulation of waste or used plastics is injection molded into new plastic product.So waste and old paper material is turned waste into wealth, and solved environmental issue, so have huge economic benefit and social benefit.
Description of drawings
Accompanying drawing of the present invention is a composite paper-plastic material separation equipment structural representation
Among the figure: 1, control panel 2, separation equipment body 3, heating plate 4, heater 5, composite paper-plastic material
The specific embodiment
As shown in drawings, its structure is made up of separation equipment body 2, heating plate 3, heater 4; In the upper end of separation equipment body 2 control panel 1 is housed; The heating plate 3 of steel is housed in separation equipment body 2, electric heater 4 is housed in the lower end of heating plate 3.Its operation principle is: at first waste and old composite paper-plastic material bag both sides are cut off, the base is cut off, and forms the composite paper-plastic material of two sheet of planar.Then a composite paper-plastic material of folding about 20 is put into the upper end of the heating plate 3 in the separation equipment body 2.Operation control panel 1 then, if composite paper-plastic material is thin then the control operation temperature is about 180 ℃, heat and got final product in 30 seconds, this moment is through eye-observation, find that next plastic shrink of opening is offed normal and can be extracted out, heat treated is carried out on the last plane that makes top a piece of paper plastic composite materials fall into heating plate 3 again.
