Resin into the plastic process is

Resin into plastic what was the process of the plastic industry including resin production preparation and plastic products, plastic production three parts. The manufacturing process of resin is a lot of small molecule materials ( Monomer) Through polymerization, polymer compounds. Elements such as the monomer composition and structure change, the polymerization can be divided into addition polymerization and polycondensation reactions. Monomer addition together called polymerization reaction, such as polyethylene, ethylene ( Monomer) Open the double chain, let each ethylene molecule ' 'hand in hand to form polyethylene. Polycondensation reaction is in the process of reaction, in addition to the formation of polymer, but also produce low molecular by-products such as water, alcohol, ammonia. How to become a plastic resin? In today's society puts forward higher and higher requirements for plastic products, such as plastic, with a single synthetic resin manufacturing in performance is difficult to meet the requirements of diversification and high quality at the same time. Therefore, usually adopt the method of 'modification, add various kinds of additives in synthetic resin, change performance, make single limited categories of resin in a variety of excellent performance of new materials. Plastics industry of the last step is the plastic molding, plastic into a certain shape of objects or materials. Plastic molding process is as follows: first, the polymer pellet or powder into plasticity flow dynamics, is usually made up by heat melt or solution, emulsion or paste, then the flow of plastic mold cavity, or stretch film, or by the spinneret spinning, etc. , forming after cold cure. For fiber and film pass stretching orientation, processing after annealing, quenching, etc, in order to achieve the stability of the product shape, and the required performance. From here also can see, resin can be made from plastic products, also can be made into fibers.
