Colophony classifies colophony to have the branch of natural colophony and synthetic resin by origin. Natural colophony is to point to by the amorphous organic material that plant secretion earnings uses in nature, wait like glue of colophony, amber, bug. Synthetic resin is to point to the colophony result that be synthesized by chemistry of classics of simple and organic matter or gets, wait like phenolic aldehyde colophony, polyvinyl chloride colophony, among them synthetic resin is plastic bases. Colophony is pressed by synthesis reaction method classification presses this method to be able to get together resorcinol to add content and condensation polymerization content. Add get together content is the polymer that shows by addition polymerization reaction is made, the structural formula of the chemical type of structure of its chain link and monomer is same, like polyethylene, polystyrene, get together 4 fluorine ethylene. Condensation polymerization content is the polymer that shows by condensation polymerization reaction is made, the structural formula of the chemical type of its construction unit and monomer is different, wait like phenolic aldehyde colophony, polyester colophony, polyamide colophony. Colophony is pressed by the element advocate catenary composition will classify can be resorcinol carbolic catenary polymer, miscellaneous catenary polymer and element by this method organic polymer. Carbolic catenary polymer is to point to advocate the polymer that catenary makes by carbolic atom completely, wait like polyethylene, polystyrene. Miscellaneous catenary polymer is to point to advocate the polymer that the atomic place that waits for element of two kinds of above by carbon and oxygen, nitrogen, sulfur makes chain, like polyformaldehyde, polyamide, get together sulphone, get together ether. Element organic polymer is to point to advocate carbolic atom is not contained certainly on catenary, the atom that basically waits for an element by silicon, oxygen, aluminous, titanium, boracic, sulfur, phosphor is formed, be like organic silicon. Colophony presses by physico-chemical property classification heats up solid sex colophony (glass reinforced plastics uses this kind of resin commonly) : Not saturated polyester / vinyl ester / annulus oxygen / phenolic aldehyde / acyl of double Ma Lai inferior amine (BMI) / get together acyl inferior amine colophony. Thermoplastic colophony: Polypropylene (PP) / polycarbonate (PC) / nylon (NYLON) / get together ether aether ketone (PEEK) / get together ether sulphone (PES) etc. Synthetic resin is by artificial complex polymer of a kind of high polymer. The application with fundamental synthetic resin is to make plastic. Improve performance to facilitate treatment is mixed, chang Tian adds auxiliary, also use at machining figuration directly sometimes, reason often is plastic synonymous language. The fundamental raw material that synthetic resin still makes synthetic fibre, coating, adhesive, insulating material wait. Synthetic resin sort is various, among them polyethylene (PE) , polyvinyl chloride (PVC) , polystyrene (PS) , polypropylene (PP) it is 5 big general colophony with ABS colophony, it is application is extensive synthetic resin data. Master resinous knowledge, also be necessary to consumer, you are OK more deepness understands the product that you use is which kind of colophony, thereby ego the safety performance that controls a product.
