I-synthetic resin iyinhlanganisela ye-polymer, ekhiqizwa ngokuhlanganisa izinto zokusetshenziswa eziphansi zamangqamuzana - ama-monomers (njenge-ethylene, i-propylene, i-vinyl chloride, njll.) ibe ngama-macromolecules ngokusebenzisa i-polymerization.Izindlela ze-Polymerization ezivame ukusetshenziswa embonini zifaka i-polymerization ngobuningi, i-polymerization yokumiswa, i-emulsion polymerization, i-polymerization ye-solution, i-slurry polymerization, i-gas phase polymerization, njll. Izinto zokusetshenziswa zokwenziwa kwama-synthetic resins ziningi.Ezinsukwini zokuqala, ikakhulukazi kwakuyimikhiqizo yetiyela yamalahle kanye ne-calcium carbide calcium carbide.Manje sekuyimikhiqizo kawoyela negesi yemvelo, efana ne-ethylene, i-propylene, i-benzene, i-formaldehyde ne-urea.
I-Ontology aggregation
I-Bulk polymerization inqubo yokwenza i-polymerization lapho ama-monomer enziwa i-polymerized ngaphansi kwesenzo sabaqalisi noma ukushisa, ukukhanya, nemisebe ngaphandle kokwengeza enye imidiya.Isici siwukuthi umkhiqizo uhlanzekile, akukho ukuhlukaniswa okuyinkimbinkimbi nokuhlanzwa okudingekayo, ukusebenza kulula, futhi izinga lokusebenzisa imishini yokukhiqiza liphezulu.Ingakwazi ukukhiqiza ngokuqondile imikhiqizo yekhwalithi ephezulu njengamapayipi namapuleti, ngakho-ke ibizwa nangokuthi i-block polymerization.Okubi ukuthi i-viscosity yezinto ezibonakalayo ikhula ngokuqhubekayo nenqubekelaphambili ye-polymerization reaction, ukuxuba nokudlulisa ukushisa kunzima, futhi izinga lokushisa le-reactor akulula ukulawula.Indlela ye-polymerization ngobuningi ivame ukusetshenziswa ekukhiqizeni ama-resin afana ne-polyadditional methyl acrylate (evame ukubizwa ngokuthi i-plexiglass), i-polystyrene, i-polyethylene ephansi, i-polypropylene, i-polyester ne-polyamide.
ukumiswa kwe-polymerization
I-Suspension polymerization ibhekisela kunqubo ye-polymerization lapho i-monomer ihlakazeka ibe ngamaconsi ngaphansi kwesenzo sokunyakaziswa komshini noma ukudlidliza kanye ne-dispersant, futhi ngokuvamile imisiwe emanzini, ngakho-ke kubizwa nangokuthi i-polymerization yobuhlalu.Izici: kukhona amanzi amaningi ku-reactor, i-viscosity yezinto ezibonakalayo iphansi, futhi kulula ukudlulisa ukushisa nokulawula;ngemuva kwe-polymerization, idinga kuphela ukudlula ngokuhlukanisa okulula, ukuwasha, ukomisa nezinye izinqubo ukuze uthole umkhiqizo we-resin, ongasetshenziswa ngokuqondile ekubumbeni ukubunjwa;umkhiqizo umsulwa ngokulinganayo, ngokulinganayo.Okubi ukuthi amandla okukhiqiza we-reactor kanye nokuhlanzeka komkhiqizo akukuhle njengendlela yobuningi be-polymerization, futhi indlela eqhubekayo ayikwazi ukusetshenziselwa ukukhiqiza.I-polymerization yokumiswa isetshenziswa kabanzi embonini.
