The production process of modified plastic particles mainly includes: mixing process, extrusion process, packaging.
Mixing.
1. Six tests of mixing: billing, receiving, cleaning, dividing, swinging, mixing.
2. Machine cleaning: it is divided into four grades A, B, C and D, of which An is the highest (smooth surface), and so on.
3. Material sharing: ensure that the relevant raw materials will not be mistaken in the operation.
4. Mixing: the order of general mixing is: particle powder, toner.
Ⅱ. Feeding.
Through computer control, blanking is controlled according to weight change.
Advantages:
1. Ensure the accuracy of material proportion.
2. Reduce the delamination of materials.
Ⅲ. Screw plasticizing, extrusion, drawing.
Ⅳ. Water cooling (sink).
Cool and cool the plastic strip extruded from the extruder.
Ⅴ. Air drying (water pump, air knife).
Remove the moisture from the plastic strip and dry it.
Ⅵ. Granulation.
Generally, the size of the cut particles is 3mm*3mm PVC material standard: GB/T8815-2002.
Ⅶ. Sifting (vibrating screen).
Filter the cut particles and control the size of the particles.
Ⅷ. Overmagnetization (magnetic filter).
Suck out particles with iron impurities.
Ⅸ. On-site inspection.
It is mainly the appearance control, which detects whether the color of the particles is up to the standard and whether it is unified.
Ⅹ. Mixing (double cone rotary mixer).
Ensure that the color and performance of the modified plastic particles are uniform.
Ⅺ. Packaging (all-electronic quantitative packaging machine).
Ⅻ. Storage
