Abstract
A kind of plastic working method, comprises the following steps：Waste or used plastics are crushed using pulverizer first, preliminary crushing is carried out using 0.95 1.15MPa pressure；Pre- fine powder is carried out using 1.2~1.25MPa pressure broken；Plastic residues after crushing are put into by concentrated nitric acid pond or concentrated sulfuric acid pond using 1.3MPa pressure progress fine powder broken (2), pulled out after immersion 23；(3) by waste plastics cleaning, broken, drying until moisture content disappears；(4) rigid plastics is put into screw extruder, by the granulation outcome of screw extruder, obtains plastic grain；(5) overlay film is carried out to plastic grain, waste or used plastics are first put into acid bath and handled by a kind of plastic working method proposed by the present invention, are in order to waste or used plastics are carried out into pickling, the impurity and residual particles on waste or used plastics are cleaned, the cleanliness of the plastic grain of production is improved.
Description
Technical field
The invention belongs to technical field of plastic processing machinery, and in particular to a kind of plastic working method.
Background technology
At present, food pack, agricultural film, woven bag, beverage bottle plastic tub, bucket, toy, old sandals, vehicle bumper, family
Waste material during electrical appliance shell and plastics processing etc., the white pollution of substantial amounts of discarded object formation is directly threatened
Environment for the survival of mankind, the recyclings of waste or used plastics as one save the energy, environmental protection measure, just increasingly
It is taken seriously.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of plastic working method.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of plastic working method, comprises the following steps：
(1) waste or used plastics are crushed using pulverizer first, preliminary powder is carried out using 0.95-1.15MPa pressure
It is broken；Pre- fine powder is carried out using 1.2~1.25MPa pressure broken；Fine powder is carried out using 1.3MPa pressure broken.
(2) pulled out after the plastic residues after crushing being put into concentrated nitric acid pond or concentrated sulfuric acid pond, immersion 2-3；
(3) by waste plastics cleaning, broken, drying until moisture content disappears；
(4) rigid plastics is put into screw extruder, by the granulation outcome of screw extruder, obtains plastic grain；
(5) overlay film is carried out to plastic grain.
It is preferred that, the acid strength in the concentrated nitric acid pond or concentrated sulfuric acid pond is 85-90%；
It is preferred that, the temperature of the crushing is 80-90 DEG C..
The beneficial effects of the present invention are：Waste or used plastics are put into acid bath first to be handled, are in order to by waste and old modeling
Material carries out pickling, cleans impurity and metallic particles on waste or used plastics, improves the cleanliness of the plastic grain of production.
Embodiment
