[0041] Working or installation process:

[0042] The first step is to preheat the mixer so that the temperature inside the mixer reaches 60 degrees Celsius to 80 degrees Celsius;

[0043] In the second step, each ingredient is weighed and poured into a high-speed mixer for stirring. The order of adding the ingredients is as follows: 50 parts of type V PVC resin, 9 parts of dioctyl phthalate, 16 parts of dioctyl terephthalate, and 4 parts of chlorinated polyethylene are poured into the high-speed mixer for stirring and stirring for 5 minutes.
