How the oil into plastics

Plastics industry, including resin, plastic and plastic products prepared in three parts. Resin manufacturing process is the raw material of many small molecules (monomers) linked by polymerization into polymers. Single element, such as by changes in the composition and structure of points can be added into the polymerization and condensation polymerization reactions. 

 

Addition polymerization reaction of monomers together is called polymerization reactions, such as polyethylene, the ethylene (monomer) of double-stranded open, so that each ethylene molecule, "Hand in Hand" on the formation of polyethylene. Polycondensation reaction process in addition to the formation of polymer addition, and also produce water, alcohol, ammonia and other low molecular weight by-products. 

 

How to become a plastic resin, then? Today's society of plastic products made increasing demands, such as the use of a single resin and plastics, while the performance is difficult to meet the diverse, high quality requirements. Therefore, usually a "modified" approach, synthetic resin in a variety of additives added to change the performance, so that a single type of resin into a limited variety of new materials with excellent properties. 

 

The final step in the plastics industry of plastic molding, is to have some plastic into the shape of the object or shape material. Plastic molding process as follows: First, the polymer pellets or powder into the flow of dynamic plasticity, usually by heating or melting paired solution, lotion or paste, and then the flow of plastic mold cavity filled, or cast into membrane, or spinneret, spinning, etc., after forming condensation curing. For the tensile fiber and film go through orientation, annealing, quenching, after processing in order to achieve stability in the product shape and the required performance. From here can see that both can be made into plastic resin can also be made into fiber.
