Abstract
The invention discloses a production technology for large-diameter organic glass extrusion rods. The production technology comprises the following steps: adding material into a plastic extruding machine through a feed opening; carrying out segmental heating and smelting to materials in a plurality of heating zones; carrying out vacuum suction filtration in the heating zone of the extruding machine, which is close to an extrusion port; extruding the smelted material from the extrusion port; sizing the material extruded from the extrusion port; under the guiding of a guidance device, reducing the temperature of the extrusion rod to be a room temperature for shaping by adopting an air cooling manner. The extrusion molding technology provided by the invention is used for producing large-diameter organic glass extrusion rods, and due to the adoption of a vacuum exhausting type material drying-free device, small impurities in raw material are effectively eliminated; a novel cooling system is adopted, so that the problems of product distortion, bending, contractile vacuole and the like can be solved.
Description
Technical field
The present invention relates to a kind of heavy caliber lucite and extrude the production technology of rod.
Background technology
It is to be made organic glass products by extruding-out process that lucite is extruded rod, and fabulous light transmission is arranged, and higher mechanical strength has certain heat-resisting cold resistance, and corrosion-resistant, insulating properties are good, and dimensionally stable can require the transparent configuration spare of some strength.Lucite is extruded rod and is widely used at aspects such as commerce, light industry, building, chemical industry, yet along with the expanded range of its application, also more and more higher to its requirement.Although the producer of domestic production organic glass products is a lot, the production and processing ability is very large, and production scale is little, product structure is very unreasonable, can only production common variety product, demand that all can not satisfying the market aspect kind and quality, the product of some high added values, high technology content is not enough.Extrude rod as ornament materials such as lucite, different sizes can be applied to the effect that different places reaches decoration, and have light transmission and the workability stronger than glass, decorative effect that fully can instead of glass also improves security, could satisfy special requirement but need bigbore lucite to extrude rod.
Yet small-bore Product Process is ripe in the prior art, and the heavy caliber lucite is extruded the rod production process imperfection, can not large-scale production.In addition, lucite extrude the rod after passing extruder head, enter the delivery track moulding before, must cool off through cooling system, and cooling system of the prior art, mostly use water cooling, water-cooled can not solve the problem that lucite is extruded the interior contractile vacuole in the rod well, and during cooling the cooling inequality can cause product crooked, lose circle, affect product quality, demand urgently improving.
Summary of the invention
For the problem that prior art exists, the object of the invention is to propose the production technology that a kind of heavy caliber lucite is extruded rod, extrude the quality of rod to improve lucite.
A kind of heavy caliber lucite is extruded the production technology of rod, may further comprise the steps:
Material is joined in the plastic extruder by charging aperture;
Described material is in the heat stepwise melting of a plurality of thermals treatment zone;
Carry out vacuum filtration at extruder near the thermal treatment zone of extrusion;
Material after the melting is extruded from extrusion;
The material that is extruded from extrusion is carried out sizing;
Under the guiding of guiding device, adopt air cooling way that the rod of extruding of moulding is down to the room temperature typing.
Preferably, also comprise as required and cut again, check, pack, put in storage.
Preferably, described a plurality of thermal treatment zone is 7.
Preferably, the temperature setting of described 7 thermals treatment zone is respectively 145 ℃, 150 ℃, 190 ℃, 170 ℃, 168 ℃, 168 ℃, 160 ℃.
Preferably, the speed that is extruded from described extrusion of described material is 2-3m/h.
Preferably, the temperature of charge of described extrusion is 120 ℃.
Preferably, the diameter behind the described sizing is 150mm.
Extruding-out process among the present invention is produced the heavy caliber lucite and is extruded rod, has used the vacuum exhaust formula to exempt to dry by the fire materials device, has effectively got rid of the little molecule in the raw material; Adopted novel cooling system, solved product and lost the problems such as circle, bending, contractile vacuole.
Description of drawings
Fig. 1 is that a kind of heavy caliber lucite is extruded the rod production process flow chart in the embodiment of the invention.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment:
The embodiment of the invention provides a kind of heavy caliber lucite to extrude the production technology of rod, as shown in Figure 1, may further comprise the steps:
Then step 107 is cut as required again, check, packs, is put in storage.
The embodiment of the invention provides the above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
