【 The news. A large variety of synthetic resin roof tile cold resistant ability is good
application is important to create plastic synthetic resin. To facilitate 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. Various 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. Synthetic resin for polymer synthetic resin, synthetic resin variety is made up 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.

first, roofing, size accurate, juncture easy lap, parity error is small, the quality of a good roofing tile, after the shop is good either horizontal or vertical or inclined, is present in a straight line, like printed, very beautiful, and a few big error of roofing tile, will not spread into a straight line. Secondly, fastness to weathering, and still do not fade, color no matter how many years experience, still bright as before, but many other types of tile, due to production, uniform coating enough, or simply to use spray paint, only a thin layer, so easy to fade, mottled, is not beautiful. Roof tile, after cold resistant ability is good, especially in the cold north, often outdoor temperature about 10 degrees below zero, if the density is too low, it makes roofing tile absorbent is too strong, just can make roofing tile expansion and brittle is too strong. The content of the
the above introduction is about the variety of synthetic resin roof tile good cold resistance ability ', we see our introduction, and the understanding of the content in this area is enough. Besides this, we in the article also introduces for everybody resin composite tile, manufacturers, wholesale, and other content, attention please!
