[0037] I: First, decompose the plastic of the waste refrigerator, crush it first, and separate the high-density impurities in it from the plastic block through cleaning, and complete the first step of decomposition;
[0038] II: Pyrolysis the processed plastic block, then put the plastic block into the melting furnace for high temperature treatment, melt the plastic block, add stabilizer barium isozincate, Plasticizer chlorinated paraffin and lubricant barium stearate, and the mixture produced by them is stirred and mixed through the stirring rod in the dissolving furnace, so that the substances in the dissolving furnace can react more completely;
[0039] III: Cool the mixture after mixing, and cool the mixture to a certain extent by air-cooling to ensure that it will not be too diluted or too hard, which is convenient for subsequent granulation;
[0040] IV: The mixture falls into the interior of the granulator, and the mixture is dry-pressed through the mold, and then the e...
