Abstract
The invention discloses a kind of method of plastic injection processing, comprise the following steps：Obtain plastic grain and cleaning treatment is carried out to plastic grain, plastic grain is put into nonionic surfactant solution and soaked, then plastic grain is put into clear water and cleaned, then plastic grain is put into alkaline solution again and soaked, then plastic grain is put into clear water and cleaned；Plastic grain after cleaning is put into dryer and dried；Plastic grain is put into injection machine, carrying out heating to it makes its fusing；The plastic grain under molten condition is injected in mold cavity by the injection device in injection machine；Mould type cavity pressure is kept until the plastic grain under molten condition solidifies；Plastic products after shaping are removed from the molds.The present invention is first cleaned by the plastic grain for obtaining the recycling and processing device of waste or used plastics, then carries out injection molding, and operating efficiency is high, and the cost of equipment is low, and preparation method is simple.
Description
Technical field
The present invention relates to a kind of field of plastics processing, and in particular to a kind of method of plastic injection processing.
Background technology
Polycarbonate plastic is widely used in clothing industry, construction material, agricultural, mechanical industry etc..Regeneration
Grain is one kind of plastic grain, may be utilized in fabricating life appliances such as various polybags, bucket, basin, toy, furniture, stationery and various
Plastic products, critically important effect is played in life, be one of most widely used plastics in the world today, because it has
Good water resistance, thermal insulation, insulating properties, agent of low hygroscopicity and stronger shock strength, and its light, firm, easy-formation, valency
The features such as lattice are low, be widely used and pack, be incubated, waterproof, heat-insulated, damping, decoration, the field such as catering trade, infiltrate through its people
Economic each department.
With developing rapidly for plastic products industry, substantial amounts of plastic products widely use, and have supervened substantial amounts of
Waste plastic, these discarded potential hazards to caused by environment, it has also become the environmental problem of Chinese society all circles concern, discard modeling
The regeneration of material has received the attention of all circles.
The content of the invention
For above-mentioned the deficiencies in the prior art, the technical problems to be solved by the invention are：How to provide a kind of using useless
The method for abandoning the plastic injection processing of the progress plastic products making of plastic reclaimed plastic grain.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：
A kind of method of plastic injection processing, comprises the following steps：
1）Obtain plastic grain and cleaning treatment is carried out to plastic grain, plastic grain is put into nonionic surfactant solution
In carry out immersion 5~10 minutes, then plastic grain is put into clear water and cleaned 5~10 minutes, then again puts plastic grain
Enter and soaked 5~10 minutes in the alkaline solution that pH value is 11~12, then plastic grain is put into clear water and cleaned 5~10 minutes；
2）Plastic grain after cleaning is put into dryer, constant weight is dried in 45~55 DEG C of temperature；
3）Plastic grain is put into injection machine, carrying out heating to it makes its fusing；
4）The plastic grain under molten condition is injected in mold cavity by the injection device in injection machine；
5）After the plastic grain being full of in mold cavity under molten condition, mould type cavity pressure is kept until under molten condition
Plastic grain solidification；
6）Plastic products after shaping are removed from the molds.
Because waste plastic is all that its own surface carries spot from collected by rubbish heap and various cemeteries,
In the present invention, first pass through and these are cleaned by the obtained plastic grain formed of waste plastic, then carry out melting injection and add
Work, finally give plastic products.
As optimization, before the injection of step 4 injection machine, first mould is cleaned, mould is immersed in mold clean
In agent, soak time 5~7 minutes, soaking temperature is 45~55 DEG C, and wherein die cleaning agent is made by following quality proportioning：10
Part deionized water, 4 parts of ethanol, 2 parts of potassium hydroxide and 4 parts of sodium hydroxides, take out mould and rinsed well using clear water, and be dried to
Constant weight.
As optimization, in step 1, plastic grain is put into nonionic surfactant solution, while utilizes ultrasonic wave
Vibrated, ultrasonic frequency is 25~45KHz.
In summary, the beneficial effects of the present invention are：The present invention is by the way that the recycling and processing device of waste or used plastics is obtained
Plastic grain first clean, then carry out injection molding, operating efficiency is high, and the cost of equipment is low, and preparation method is simple.
