Abstract
The invention relates to a process for producing a polyethylene (PE) pipeline by using waste plastics, in particular to the production of a liquid conveying pipeline by mixing the regenerated waste plastics with new particles, and belongs to the technical field of injection molding. The process has the technical characteristics of comprising the production of returned material particles and the PE pipeline and is characterized in that the returned material particles are placed in a master and secondary wire drawing grain cutting machine to be cut into small particles with a size of about 4mm at the decomposition temperature of 60 to 180 DEG C; and the returned material particles are mixed with the first used plastic particles in a weight ratio of 7:3. The process has the advantages of strong adaptability, high flexibility, simple operation, reliable performance and the like.
Description
Technical field
The present invention relates to a kind of production technology of the PE of making pipeline, relate in particular to and a kind ofly utilize after the waste plastics recycling and new particle mixing manufacture liquid conducting pipes, belong to the injection molding technology field.
Background technique
Known PE pipeline generally all is to be raw material with high molecular polymers such as polyethylene, polypropylene, forms through the injection machine high-temperature injection.Its raw material generally comes from the tankage after the Petroleum refining to be produced.Because high molecular polymers such as polyethylene, polypropylene have the effect of utilizing again through high temperature processing, and high molecular polymer leftover pieces such as a large amount of polyethylene, polypropylene are arranged on the market or use after waste material, requirement is not too high to some pipeline to raw material in addition, and this just brings a research topic of utilizing waste plastics such as polyethylene, polypropylene high molecular polymer for raw material to us.
Summary of the invention
For the PE pipeline is produced in the plastic pellet comprehensive utilization of waste or used plastics particle and use first, the present invention proposes a kind of production technology of utilizing waste plastics to make the PE pipeline.
To achieve these goals, the technical solution adopted in the present invention is: 1, and the making of feed back particle: comprise cleaning, select materials, drench is done, pulverizing, granulation.2, the making of PE pipeline: comprise mixing, fusion, injection moulding.
Cleaning in the step 1 is meant: the old plastics that reclaim are slightly washed in the pond and washed, enter to rotate again and add washing agent in the washing machine or caustic soda cleans half an hour;
Select materials and be meant:, will classify by polyethylene, polypropylene, PVC etc. through the waste plastics after cleaning according to the constituent difference;
Drench is dried to be meant: cleaned fritter waste material is done through Haug drainer dehydration or drench;
Pulverizing is meant: be ground into 1cm left and right sides fritter entering fine pulverizer through the unit of plastic after the above-mentioned steps by classification, pack;
Granulation is meant: the little lump waste materials after pulverizing is put into primary and secondary wire drawing pelleter, under the situation of 60-180 ℃ of decomposition temperature, approximately earnestly become the segment particle about 4mm.
Mixing in the step 2 is meant: the plastic pellet of feed back particle and use was first mixed by weight 7: 3, and stir;
Fusion is meant: the heating cabinet of stuff and other stuff being put into 200 ℃ of left and right sides environment adds thermal agitation until becoming pasty substances;
Injection moulding is meant: will put into extruding equipment through the pasty substances of fusion and produce the PE pipe.
It is characterized in that the feed back particle puts into primary and secondary wire drawing pelleter, under the situation of 60-180 ℃ of decomposition temperature, approximately earnestly become the segment particle about 4mm; The plastic pellet of feed back particle and use first was by weight 7: 3.
The present invention had both had environmental protection, energy-conservation, social effect such as turn waste into wealth, and had economic benefits such as the cost of material is low, material source is wide, produce market is big again.
Embodiment
The invention will be further described to closing concrete enforcement below; At first the waste or used plastics collected or the leftover pieces of plastic production are classified, be divided into according to the constituent difference: polyethylene, polypropylene, PVC etc.The polyethylene waste material of different colours is torn into the 5-10cm fritter through shredmaster, pulverizes entering fine pulverizer, be ground into 1cm left and right sides fritter, pack being torn into the 5-10cm fritter.The fritter that is processed into 1cm is slightly washed in the pond, removed dirt, impurity is removed in rinsing, and water washes; Enter to rotate and add washing agent in the washing machine or caustic soda cleans half an hour.Cleaned fritter waste material is done through Haug drainer dehydration or drench.The little lump waste materials that has taken off water is put into primary and secondary wire drawing pelleter, under the situation of 60-180 ℃ of decomposition temperature, approximately earnestly become the segment particle about 4mm.Oven dry or dry pack.Material polyethylene and feed back are mixed by weight 3: 1 ratios, and the heating cabinet of stuff and other stuff at first being put into 200 ℃ of left and right sides environment adds thermal agitation until becoming pasty substances; To put into extruding equipment through the pasty substances of fusion and produce the PE pipe.
Claims (2)
1. production technology of utilizing waste plastics to make the PE pipeline, technological scheme is: 1, the making of feed back particle: comprise cleanings, select materials, drench is dried, pulverizing, granulation; 2, the making of PE pipeline: comprise mixing, fusion, injection moulding, it is characterized in that the feed back particle puts into primary and secondary wire drawing pelleter, under the situation of 60-180 ℃ of decomposition temperature, approximately earnestly become the segment particle about 4mm.
2. a kind of production technology of utilizing waste plastics to make the PE pipeline as claimed in claim 1, the plastic pellet that it is characterized in that feed back particle and use first was by weight 7: 3.
