Go out in machine, sandwich layer slurry is formed by extruding；
4th step：Sandwich layer slurry and top layer slurry are filled into mould respectively（Sandwich layer slurry and top layer slurry groundwater increment ratio
It is 8:2）, extruding is mixed in mould, form section bar；
Two charging apertures of mould carry out slurry perfusion simultaneously（Sandwich layer slurry and top layer slurry groundwater increment ratio are 8:2）, charging
Perfusion is the interior sandwich layer slurry out of the double screw extruder of standard 65 in mouth 14, and sandwich layer slurry flows through flat flow channel 15, first
Runner 16, second flow channel 17 and third flow channel 18 form the top layer slurry warp of extrusion in the profile of section bar, 47 double screw extruders
Upside charging aperture 22 enters core material runner 23, then enters membership stream plate 3 through third flow channel 18, in the third flow channel 18 that can flow plate 3,
Top layer slurry and sandwich layer slurry can flow, and top layer slurry carries out cladding treatment in cladding road 24 to section bar, then through first
The extrusion die of discharging opening 23 shaping of the mouth template 1 of third flow channel 18 and second of mouth template 2；Die size is 600mm*400mm,
Template thickness 25-50mm, is that the twice of existing mold is more, mould inner flow passage diameter increase, so that into the material in mould
Slurry disclosure satisfy that the forming requirements of the section bar of multiple discharging openings 23；Cladding road 24 is designed as surrounding the outside of third flow channel 18 one week,
The operation of full cladding can be realized carrying out the inner profile of third flow channel 18, so as to produce full cladding section bar；Through fixed between mould
Position pin is positioned, it is ensured that assembly precision, and is attached using screw, and the displacement of mould will not occur in process；
The two ends of after-poppet 5 are provided with fixed mount 22, and mould can be fixed, it is ensured that the stabilization in processing；In mould
Three runners 18 can be 6, or 8, even more many, and a multi-cavity mold is to be designed to realize that mould one goes out many behaviour
Make, as long as the slurry of perfusion disclosure satisfy that requirement, it is possible to realize producing simultaneously the work of many section bars；
Active response comprehensive utilization of resources of the present invention and the call of energy-saving and emission-reduction, building material " environmental protection, hair are advocated by country
Exhibition recycling economy promotes waste and old material regeneration ", the design and the improvement of equipment die of done novel process；The present invention
The secondary release of the material property brought according to the characteristic of PVC material, " secondary plasticizing ", in some simple auxiliary agents of addition,
So that the material resources performance of the script of product is greatly improved；Top layer material effectively solves products application Environment-friendlycalcium calcium zinc stabilizer institute band
The unstability come and problem is separated out, and no longer make because lead salt stabilizer has micro- poison and is eliminated not possessing acid rain preventing effect
With；Top layer material consumption is less（The ratio of core material and skin-material extrusion capacity is 8:2）, the present invention improve top layer material into
This, so that product has more glossiness and anti-aging performance；Waste and scrap cannot largely be reclaimed in original technique
Utilize, and the present invention can reach more than 70% using the ratio of waste polyvinyl chloride, effectively reduce cost, and to waste and old
Polyvinyl chloride is recycled, it is to avoid the pollution and destruction of environment.
Top layer of the invention and sandwich layer use different formulas（The ratio of core material and skin-material usage amount is 8:
2）, sandwich layer requirement is relatively low, so the ancillary additions of costliness need not be added, and uses substantial amounts of waste polyvinyl chloride, can be with
Substantial amounts of Material Cost is saved, the extra-pay needed for reducing waste disposal can effectively control cost；The present invention is made
47 twin-screws, can strengthen the density of extruded slurry so that can using the slurry made by waste polyvinyl chloride
Meet national standard requirement；The mould of a multi-cavity mold used during production, by the size and mould inner flow passage that increase mould
Diameter, realize multiple flow passages work simultaneously and the full cladding section bar of production purpose, go out many processing modes using one, so as to improve
Operating efficiency, improves output.
