Description
Technical field
The present invention relates to the production technology that rod extruded by a kind of heavy caliber lucite.
Background technology
Rod extruded by lucite is obtained organic glass products by extruding-out process, has fabulous light transmission, higher mechanical strength, has certain heat-resisting cold resistance, and corrosion-resistant, insulating properties are good, and dimensionally stable, can require the transparent configuration part of some strength.Lucite is extruded rod and is widely used in business, light industry, building, chemical industry etc., but along with its expanded range applied, also more and more higher to its requirement.Although the producer of domestic production organic glass products is a lot, production and processing ability is very large, and production scale is little, product structure is very unreasonable, can only production common variety product, in kind and quality, all can not meet the demand in market, the product of some high added values, high technology content is not enough.Such as lucite extrudes rod as ornament materials, different sizes can be applied to the effect that different places reaches decoration, and there is the light transmission stronger than glass and workability, can substitute the decorative effect of glass completely and improve security, but needing bigbore lucite to extrude rod could meet special requirement.
But in prior art, small-bore Product Process is ripe, and rod production process imperfection extruded by heavy caliber lucite, can not large-scale production.In addition, lucite extrude rod enter after passing extruder head delivery track shaping before, must cool through cooling system, and cooling system of the prior art, most utilization water cooling, water-cooled can not solve the problem that the interior contractile vacuole in rod extruded by lucite well, and during cooling, cooling inequality can cause product to bend, lose circle, affect product quality, urgently improve.
Summary of the invention
For prior art Problems existing, the object of the invention is to propose the production technology that rod extruded by a kind of heavy caliber lucite, to improve the quality that rod extruded by lucite.
A production technology for rod extruded by heavy caliber lucite, comprises the following steps:
Material is joined in plastic extruder by charging aperture;
Described material is in the heat stepwise melting of multiple thermals treatment zone;
Vacuum filtration is carried out near the thermal treatment zone of extrusion at extruder;
Material after melting is extruded from extrusion;
Sizing is carried out to the material be extruded from extrusion;
Under the guiding of guiding device, air cooling way is adopted to be down to room temperature sizing to shaping rod of extruding.
Preferably, also comprise and carry out again as required cutting, check, pack, put in storage.
Preferably, described multiple thermal treatment zone is 7.
Preferably, the temperature of described 7 thermals treatment zone arranges and is respectively 145 DEG C, 150 DEG C, 190 DEG C, 170 DEG C, 168 DEG C, 168 DEG C, 160 DEG C.
Preferably, described material is 2-3m/h from the speed that described extrusion is extruded.
Preferably, the temperature of charge of described extrusion is 120 DEG C.
Preferably, the diameter after described sizing is 150mm.
Extruding-out process in the present invention is produced heavy caliber lucite and is extruded rod, has used vacuum exhaust formula to exempt to dry materials device, has effectively eliminated the Small molecular in raw material; Have employed novel cooling system, solve the problems such as product mistake is round, bending, contractile vacuole.
Accompanying drawing explanation
Fig. 1 is that in the embodiment of the present invention, rod production process flow chart extruded by a kind of heavy caliber lucite.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing:
Embodiments provide the production technology that rod extruded by a kind of heavy caliber lucite, as shown in Figure 1, comprise the following steps:
Step 101, is joined material in plastic extruder by charging aperture.
Step 102, material in the heat stepwise melting of multiple thermals treatment zone, such as, is divided into 7 thermals treatment zone, and temperature arranges and is respectively 145 DEG C, 150 DEG C, 190 DEG C, 170 DEG C, 168 DEG C, 168 DEG C, 160 DEG C.
Step 103, carries out vacuum filtration at extruder near the thermal treatment zone of extrusion, such as, in the 5th district, the moisture in material, oligomer is got rid of.In above-mentioned vacuum filtration process, carry out drying and processing without the need to material, simplify production technology, save energy consumption.Because nutsch filter is serially connected with on unit Material pipeline, while production, adopt vacuum to absorb the moisture existed in material online, moisture in material can well be got rid of, and the low-molecular material that can absorb in material, solve in the problem extruding excellent production process generation bubble and pit, improve the transparency of product, and can economize energy, raise the efficiency.
Step 104, the material after melting is extruded from extrusion, and such as extruded velocity is 2-3m/h.
Step 105, carries out sizing to the material be extruded from extrusion, and the temperature of charge of such as extrusion is 120 DEG C, the diameter 150mm after sizing.
Step 106, under the guiding of guiding device, adopts air cooling way to be down to room temperature, the final shaping to shaping rod of extruding.The wind of blower fan blowout in air cooler, the lateral wall of air cooler is passed into by wind conveying pipe, and air cooler is a closed cavity, wind can only be provided with the inwall of several equally distributed defeated air holes from it, blow to and extrude rod from the lucite of extruder head output, after making lucite extrude excellent wind-engaging, cooling evenly, can meet factory's continuous prodution in one-shot forming technique, the interior contractile vacuole that rod extruded by good solution lucite, the problem lost circle, bend, ensure that the quality of product.
Step 107, then carries out as required cutting again, checks, packs, puts in storage.
Embodiments provide the above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
