Description
Technical field
The present invention relates to resource reutilization field, more particularly to a kind of waste or used plastics to crush recovery method.
Background technology
Waste or used plastics are the general designations for the plastics in the purposes such as civilian, industrial, using and finally eliminating or replace.
As plastic products consumption figure constantly increases, waste or used plastics are also on the increase.At present China's waste or used plastics be mainly plastic sheeting,
Plastic wire, knitting, foamed plastics, plastic package box, container, daily plastic product, polybag etc..
House refuse is handled in a manner of landfill more at present due to domestic, waste or used plastics can not only take greatly with garbage loading embeading
Soil is measured, and occupied soil cannot recover for a long time, influence the sustainable use in soil.Therefore the recovery of waste or used plastics
Seem and be even more important.
Polypropylene and polystyrene are the raw materials of conventional making plastics, and the plastic product of making typically may be used to eat
Product are held, but it is cumbersome to run into edible oil cleaning up, wastes time and energy, the food especially manufactured by resource reutilization
Thing container, less easy cleaning edible oil are dirty.
The content of the invention
It is an object of the invention to provide a kind of waste or used plastics to crush recovery method, to solve above-mentioned technical problem.
The present invention using following technical scheme in order to solve the above technical problems, realized：
A kind of waste or used plastics crush recovery method, it is characterised in that comprise the following steps,
A. by weight, 20-30 part waste or used plastics particle, 2-3 part paraffin oils are placed in glycerin solution and soak 2-3
Hour, and aid in irradiating with ultraviolet；
B. pull waste or used plastics particle out, cleaned with clear water, and waste or used plastics particle and the polyacrylic acid of 0.1-0.3 parts are sent
Enter high-pressure smelting groove to be melted, temperature setting is 180-210 DEG C, and the time is arranged to 30-45 minutes；
C. the waste or used plastics particle after melting is put into the cracking still for being preheated to 180-210 DEG C, adds 1-3 part titanium dioxides
Si powder, agitating device is opened, and temperature is adjusted to 300-350 DEG C, continue 20-30 minutes；
D. 0.2-0.5 part sodium hydroxide powders are added into cracking still, the vacuum plant of later on cracking still, are made in kettle
Pressure is 100-200Pa, continues to melt 1-1.5 hours；
E. the outlet valve of cracking still is opened, material is subjected to IQF, temperature setting is -60 DEG C to -50 DEG C, during freezing
Between be 12-18 hours；
F. the material of obtained freeze-drying state in E is crushed, and particle is made by comminutor.
The present invention first passes through usual manner and waste or used plastics particle is softened, cleaned, and passes through above-mentioned raw materials and side
Method step is prepared for the material with oleophobic properties, in order to strengthen oleophobic properties, increases silica in raw material, and use hydrogen-oxygen
Change sodium to be catalyzed；IQF then changes the physical property of material, material oleophobic properties is further strengthened.
Preferably, microwave irradiation of the auxiliary using power as 2000-2500w during described IQF.
Preferably, described IQF process is carried out in 100-200pa environment under low pressure.
Preferably, microwave irradiation of the auxiliary using power as 2000-2500w during described IQF, and
Carried out in 100-200pa environment under low pressure.
It the experiment proved that, low pressure and microwave can optimize oleophobic properties, and synergy is more preferable.
Preferably, described agitating device rotating speed is arranged to 200-300 revs/min.
Preferably, the making raw material of described waste or used plastics is polypropylene, polystyrene one kind therein.
Polypropylene, polystyrene are usually used in making food container, and plastic grain prepared by the present invention then has more to edible oil
Good alienation effect.
The beneficial effects of the invention are as follows：The invention provides a kind of waste or used plastics to crush recovery method, mainly will be waste and old
Plastic grain recycling, lay equal stress on it is freshly prepared go out a kind of plastic grain with oleophobic properties.
