PVC granulation processing production process and related attention requirements.

Granulation process is to high polymer resin and all kinds of additives, additives, through measuring, stick together, plasticizing, diced into granular plastic production process, the plastic particles is plastic molding processing of semi-finished products, and such as extrusion, injection molding, blow molding, foaming molding processing production of raw materials.
The resin has two kinds: powder and grain.
Extruding method is the most basic and simple method for granulation.
For all kinds of plastic forming processing methods, the advantages of granulated granule are as follows:
(1) it is convenient to add materials, and it is not necessary to install the mandatory feeder in the hopper.
(2) the relative density of pellets is larger than powder materials, and the strength of plastic products is better.
(3) the mixture of resin and various solid powder or liquid additives is more uniform, and the physical properties of plastic products are more uniform.
(4) the color of plastic products is even.
(5) the particles are less volatile and make the plastic products less prone to bubbles.
(6) the granules are free of pollution to the extruder and the production environment.
