Description

technical field [0001] The invention belongs to the technical field of plastic material processing and discloses a processing technology of insulating plastic material. Background technique [0002] Plastic is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid, and it is a molten liquid during the manufacturing process. Therefore, it can be melted by machine heating, pressure can be applied to make it flow, and cooling can make it Solidified and formed into various shapes, this large and varied group of materials is called plastics. Plastic parts are widely used in every field of life today, such as household appliances, instruments, wires and cables, construction equipment, communication electronics, automobile industry, aerospace, daily hardware, etc. The main component of plastic raw materials is carbon-containing compounds, which are made of polymer synthetic resin (polymer) as the main component,...
