Abstract
The invention discloses a method for recycling and processing plastic to obtain plastic particles. The method comprises the following steps: step one, screening the recycled waste and old plastic, then soaking the selected plastic into an acidic liquid pool for two days, and then fishing out the plastic; step two, washing the waste and old plastic, which has been processed in the step one, by water and drying the plastic under the sun; step three, grinding the waste and old plastic, which has been processed in the step two, transferring the grinded plastic to a double-screw extruder to carry out granulation so as to obtain the plastic particles. In the provided method, the waste and old plastic is processed in an acidic liquid pool at first to carry out an acid washing treatment on the waste and old plastic so as to eliminate the impurities and metal particles on the waste and old plastic, thus the cleanness of the produced plastic particles is improved, and the application range of the plastic particles is enlarged. The provided method can effectively recycle waste and old plastic and increase the waste utilization rate.
Description
Technical field
The present invention relates to a kind of processing method of waste or used plastics, be specifically related to a kind of method that 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 plastics processing process etc., the white pollution that a large amount of discarded objects is formed directly threatens the environment that the mankind depend on for existence.The recycling of waste or used plastics, as the measure of an economize energy, protection of the environment, comes into one's own 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
Technics of reclaim of plastic waste is processed into a method for plastic grain, comprises the steps:
Step one, by the waste or used plastics of recovery sorting screening after put into acid bath, soak and pull out after 2 days;
Step 2, through step one process after waste or used plastics, rinse well with water, dry;
Step 3, the waste or used plastics after step 2 process to be smashed, enter double screw extruder, carry out granulation, namely complete the processing of plastic grain.
Further scheme is: stating acid solution main component in acid bath is nitric acid or sulfuric acid.
In the present invention, first waste or used plastics being put into acid bath and process, is to waste or used plastics be carried out pickling, washing
Impurity on clean waste or used plastics and metallic particles, improve the cleanliness of the plastic grain produced, and expands the scope of application of plastic grain.
The present invention effectively can reclaim waste or used plastics, improves the efficiency of waste or used plastics twice laid.
Detailed description of the invention
Technics of reclaim of plastic waste is processed into a method for plastic grain, comprises the steps:
Step one, by the waste or used plastics of recovery sorting screening after put into nitric acid acid bath, soak and pull out after 1 day;
Step 2, through step one process after waste or used plastics, rinse well with water, dry;
Step 3, the waste or used plastics after step 2 process to be smashed, enter double screw extruder, carry out granulation, namely complete the processing of plastic grain.
