Abstract
The invention discloses a method for recycling and processing plastic into plastic particles, which comprises the following steps: step one, putting the recycled waste plastic into an acid liquor pool, soaking for 1 day, and then fishing out; step two, washing the waste plastics treated in the step one with water, and drying in the sun; and step three, crushing the waste plastics treated in the step two, and putting the crushed waste plastics into a double-screw extruder for granulation to finish the processing of plastic particles. In the invention, the waste plastic is firstly put into an acid liquor pool for treatment, so that the waste plastic is pickled to clean impurities and metal particles on the waste plastic, the purity of the produced plastic particles is improved, and the application range of the plastic particles is expanded. The invention can effectively recycle waste plastics and improve the utilization of waste.
Description
Technical field
The present invention relates to a kind of processing method of waste or used plastics, be specifically related to the method that a kind of technics of reclaim of plastic waste is processed into plastic grain.
Background technology
Waste material in food pack, plastic sheeting for farm use, woven bag, beverage bottle plastic tub, bucket, toy, old sandals, vehicle bumper, household appliances shell and the plastic shaping process or the like, the white pollution direct threats that a large amount of discarded objects forms human environment of depending on for existence.Reclaiming and utilizing waste plastics comes into one's own as the measure of an energy savings, protection environment just day by day.
Summary of the invention
The object of the present invention is to provide a kind of technics of reclaim of plastic waste and be processed into the method for plastic grain.
The present invention is achieved in that
A kind of technics of reclaim of plastic waste is processed into the method for plastic grain, comprises the steps:
Step 1, the waste or used plastics that reclaims is put into acid bath, soak and pull out after 1 day;
Step 2, the waste or used plastics after step 1 is handled, water is rinsed well, dries;
Step 3, the waste or used plastics after step 2 handled are smashed, and get into double screw extruder, carry out granulation, promptly accomplish the processing of plastic grain.
Scheme further is: the acid solution main component is nitric acid or sulfuric acid in the said acid bath.
Among the present invention, at first waste or used plastics being put into acid bath and handle, is in order waste or used plastics to be carried out pickling, to clean impurity and metallic particles on the waste or used plastics, improve the cleanliness of the plastic grain of producing, enlarging the scope of application of plastic grain.
The present invention can effectively reclaim waste or used plastics, improves the efficient of waste or used plastics twice laid.
The specific embodiment
A kind of technics of reclaim of plastic waste is processed into the method for plastic grain, comprises the steps:
Step 1, the waste or used plastics that reclaims is put into the nitric acid acid bath, soak and pull out after 1 day;
Step 2, the waste or used plastics after step 1 is handled, water is rinsed well, dries;
Step 3, the waste or used plastics after step 2 handled are smashed, and get into double screw extruder, carry out granulation, promptly accomplish the processing of plastic grain.
Claims (2)
1. the method for plastic grain is processed in a plastics recovery, it is characterized in that comprising the steps:
Step 1, the waste or used plastics that reclaims is put into acid bath, soak and pull out after 1 day;
Step 2, the waste or used plastics after step 1 is handled, water is rinsed well, dries;
Step 3, the waste or used plastics after step 2 handled are smashed, and get into double screw extruder, carry out granulation, promptly accomplish the processing of plastic grain.
2. according to the said method of claim 1, it is characterized in that: the acid solution main component is nitric acid or sulfuric acid in the said acid bath.
