I-Synthetic resin yi-polymer compound, eveliswa ngokudibanisa izinto eziphantsi ze-molecular - monomers (ezifana ne-ethylene, i-propylene, i-vinyl chloride, njl.) kwi-macromolecules ngokusebenzisa i-polymerization.Iindlela zePolymerization eziqhelekileyo ezisetyenziswa kwishishini ziquka i-polymerization yobuninzi, i-polymerization yokumiswa, i-emulsion polymerization, i-polymerization yesisombululo, i-polymerization ye-slurry, i-polymerization yesigaba segesi, njl.Kwiintsuku zokuqala, yayiyimveliso yetar yamalahle kunye ne-calcium carbide calcium carbide.Ngoku zininzi zeoyile kunye negesi yendalo, njenge-ethylene, propylene, benzene, formaldehyde kunye neurea.
Udityaniso lweOntology
Ubuninzi bepolymerization yinkqubo yepolymerization apho iimonomers zenziwa ipolymerized phantsi kwesenzo sabaqalisi okanye ubushushu, ukukhanya, kunye nemitha ngaphandle kokongeza enye imidiya.Uphawu kukuba imveliso imsulwa, akukho kwahlulwa kuntsonkothileyo kunye nokucocwa kuyadingeka, ukusebenza kulula, kwaye izinga lokusetyenziswa kwezixhobo zokuvelisa liphezulu.Iyakwazi ukuvelisa ngokuthe ngqo iimveliso ezikumgangatho ophezulu ezifana nemibhobho kunye namacwecwe, ngoko ke kuthiwa i-block polymerization.Ukungalungi kukuba i-viscosity yezinto eziphathekayo iyanda ngokuqhubekayo kunye nenkqubela phambili ye-polymerization reaction, ukuxuba kunye nokutshintshwa kobushushu kunzima, kwaye ukushisa kwe-reactor akulula ukulawula.Indlela yobuninzi be-polymerization isoloko isetyenziselwa ukuveliswa kwee-resin ezifana ne-polyadditional methyl acrylate (eyaziwa ngokuba yi-plexiglass), i-polystyrene, i-polyethylene ephantsi, i-polypropylene, i-polyester kunye ne-polyamide.
ukumiswa kwepolymerization
Ukumiswa kwepolymerization kubhekiselele kwinkqubo ye-polymerization apho i-monomer ihlakazekile ibe ngamathontsi phantsi kwesenzo sokuvuselela oomatshini okanye ukungcangcazela kunye ne-dispersant, kwaye ngokuqhelekileyo inqunyanyiswa emanzini, ngoko ikwabizwa ngokuba yi-polymerization ye-bead.Iimpawu zezi: kukho ubuninzi bamanzi kwi-reactor, i-viscosity yezinto eziphathekayo iphantsi, kwaye kulula ukudlulisa ukushisa nokulawula;emva kwe-polymerization, idinga kuphela ukuhamba ngokuhlukana okulula, ukuhlamba, ukomisa kunye nezinye iinkqubo zokufumana imveliso ye-resin, engasetyenziselwa ngokuthe ngqo ukubunjwa kokubumba;imveliso icocekile ngokulinganayo.Ukungalungi kukuba amandla okuvelisa i-reactor kunye nokucoceka kwemveliso ayilungile njengendlela yobuninzi be-polymerization, kwaye indlela eqhubekayo ayinakusetyenziswa kwimveliso.Ukumiswa kwepolymerization kusetyenziswa kakhulu kwishishini.
