Analysis of synthetic resin
for ease of processing and improve performance, often add fertilizer, sometimes directly used for processing and forming, reason often is the synonym of plastics. Synthetic resin or synthetic fiber production, coatings, adhesives, insulation materials such as the warp and woof of raw materials.
is a great variety of synthetic resin. According to the main chain structure with carbon chain, miscellaneous chain and the carbon chain synthetic resin; According to the synthetic reaction characteristics of addition polymerization and polycondensation synthetic resin. In the practical application, often according to the thermal behavior of divided into thermoplastic resin and thermosetting resin. Among them, the thermoplastic resin such as polyethylene, polypropylene, polystyrene, polyvinyl chloride (PVC). Thermosetting resin with urea-formaldehyde resin, phenolic resin and epoxy resin, the fluorine resin, unsaturated polyester and polyurethane etc.
for macromolecular synthetic resin, resin, the composition of the material is made of low molecular material - monomer ( Such as ethylene, propylene, vinyl chloride, etc. ) After the separation of polymerization reaction into macromolecular and consumption. Commonly used in industry aggregation method with bulk polymerization, suspension polymerization, emulsion polymerization and solution polymerization of 4.
