Description
Technical field
The present invention relates to a kind of acrylic leftover pieces and clast processing methods and preparation method thereof, belong to organic glass recovery processing
Technical field.
Background technique
Acrylic is called PMMA or organic glass, is originated from English acrylic (acrylic plastics), and chemical name is poly- first
Base methyl acrylate.Acrylic is a kind of exploitation high molecular thermoplast earlier, and machine-shaping is more convenient, acrylic
The molding mode of material mainly has cast molding and extrusion forming, can also be soft by its by reheating after acrylic material molding
The mode of change is made the various shape of needs, and acrylic has the preferable transparency and a light transmittance, light transmittance up to 92%,
Chemical stability and weatherability are preferable, very strong to natural environment adaptability.
In acrylic process, the waste materials such as a large amount of leftover pieces, clast can be generated, it, can if cannot recycle
Generate vast resources waste.Existing acrylic clast recovery and treatment method is simple, and treatment effeciency is low.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of acrylic leftover pieces and clast processing method.
The technical problems to be solved by the invention take following technical scheme to realize:
A kind of acrylic leftover pieces and clast processing method, specifically include following operating procedure:
1) it recycles clast: the waste materials such as the leftover pieces, clout, clast that generate in acrylic process is collected；
2) it cleans: the big impurity (such as wooden unit, paper scrap, hair) being mixed in the waste material of centralized recovery being rejected, and passes through pulverizer
Break process is carried out, it is spare to obtain acrylic pellet；
3) it cleans: pellet being placed in the rinse bath for being marked with the supersonic wave cleaning machine of cleaning solution and impregnated 1-2 hours, immersion terminates
Afterwards, supersonic wave cleaning machine is opened, pellet is cleaned 20-30 minutes；
4) primary colors is handled: pellet being taken out from rinse bath and is drained, and pellet is put into cooker and is boiled, continues 1-3
Hour, the distilled water of its volume 3/4 is added in cooker, and the powdered sodium carbonate of distillation water quality 1-3% and taking off for 3-5% is added
Toner；
5) it rinses: the pellet in cooker is taken out, and by distilled water to pellet repeated flushing 10-20 seconds, flushing water is returned
Packaging film sealed envelope is used after receipts, is used for boiling；
6) dry: pellet being placed in 40-60 DEG C of baking oven by clean charging tray collection and is dried, it is cold that nature is taken out after drying
But spare after；
7) melting remodeling: pellet after cooling is added into crucible, to vacuumize process is carried out in crucible, until crucible internal pressure
After power is 0.05-0.07MPa, injected in crucible by nitrogen so that crucible external and internal pressure is identical, by intermediate frequency furnace to crucible into
It goes and heats, heating temperature is 460-480 DEG C, continues 2-4 hours, so that the pellet in crucible all becomes to stop adding when molten state
Heat, and fused materials are cast to the chilled glass die of preparatory surface filming, it is formed after cooling, obtains acrylic profile；
8) it stores: packaging film sealed envelope will be used after the recycling of acrylic profile, be staggeredly stacked, room temperature storage.
The cleaning solution weighs following material mixing for component by weight and forms: 1-3 parts of odium stearate, emulsifier 4-7
Part, 3-5 parts of sodium hydroxide, 20-30 parts of water.
The temperature of the cleaning solution is kept for 50-60 DEG C.
The beneficial effects of the present invention are: the present invention is conducive to by the way that acrylic waste material is carried out crushing granulation to granular original
Material is handled, and is impregnated, is cleaned by ultrasonic to bulk material by cleaning solution, can removed and be adhered to waste material in process
On carving liquid, oil stain, stain, by be added decolorising agent carry out boiling, the acrylic waste material of different colours can be restored
At primary colors, be conducive to that waste material is uniformly processed, improve waste disposal efficiency, then by melting remodeling, by waste material carry out at
Type can be used directly.
