1. If you make plastics from scratch, you have to understand basic chemistry knowledge and turn raw materials into plastics through various chemical reactions. If you have plastic and want to make plastic products, there are basically two steps, heating and molding. Heating is to melt the plastic and facilitate molding. Molding is to make the plastic what you want through various means, which can be extrusion, injection into a mold, and so on.Then just wait for it to cool down
2.Different plastics require different technologies. Generally speaking, it is polymerization, in which small molecules are linked into polymer products.
3.The raw materials of plastics are various plastic particles, which are processed by different materials through polymerization processes. Film materials are formed through stretching and other processes, and after processing, we common plastic bags and other products are formed.The plastics mentioned in the production of goods are all polymerized
