Upharafini oyi-Chlorinated uketshezi oluphuzi olusagolide olusagolide noma olu-amber viscous, olungashi, aluqhumi, futhi luphansi kakhulu. Incibilika kuzincibilikisi eziningi eziphilayo, ezingancibiliki emanzini ne-ethanol. Uma ishisiswe ibe ngaphezu kuka-120℃, izobola iyodwa kancane kancane futhi ingakhulula igesi ye-hydrogen chloride. Futhi ama-oxide ensimbi, i-zinc, nezinye izinsimbi azothuthukisa ukubola kwayo. Ipharafini ene-chlorinated iyi-plasticizer eyisizayo ye-polyvinyl chloride. Ukuguquguquka okuphansi, okungashi, akunaphunga. Lo mkhiqizo uthatha indawo yengxenye ye-plasticizer eyinhloko, enganciphisa izindleko zomkhiqizo futhi inciphise ukuvutha.
Izici
Ukusebenza kwe-plasticizing kapharafini e-chlorine 52 kuphansi kune-plasticizer eyinhloko, kodwa kungakhuphula ukufakwa kukagesi nokumelana nomlilo futhi kungathuthukisa amandla okubamba. Ububi bepharafini ekloriniwe 52 ukuthi ukumelana nokuguga kanye nokumelana nezinga lokushisa eliphansi kubi, umphumela wokubuyisela kabusha wesibili nawo awubi, futhi i-viscosity iphezulu. Kodwa-ke, ngaphansi kwesimo sokuthi i-plasticizer eyinhloko ayitholakali futhi iyabiza, upharafini ofakwe nge-chlorine 52 usasebenzisa ingxenye yemakethe.
Upharafini we-chlorinated 52 ungaxutshwa nezinto ezihlobene ne-ester, ungenza i-plasticizer ngemva kokuxuba. Ngaphezu kwalokho, ibuye ibe nezici njenge-flame retardant kanye nokuthambisa. Uma kunesidingo, kungase futhi kubambe iqhaza ku-antisepsis.
Amandla okukhiqiza kapharafini 52 anamandla kakhulu. Enqubweni yokufaka isicelo, sebenzisa ngokuyinhloko indlela ye-chlorination eshisayo kanye nendlela ye-catalytic chlorination. Ezimweni ezikhethekile, izindlela ze-photochlorination nazo zisetshenziswa.
Isicelo
I-1.I-Chlorinated parafini 52 ayincibiliki emanzini, ngakho-ke ingasetshenziswa njenge-filler kuma-coatings ukuze kuncishiswe izindleko, kwandiswe izakhiwo ezingabizi futhi ezingenamanzi nezingashi.
2.Isetshenziswa emikhiqizweni ye-PVC njenge-plasticizer noma i-plasticizer eyisizayo, ukuhambisana kwayo nokumelana nokushisa kungcono kune-parafini e-chlorinated-42.
I-3.Ingasetshenziswa futhi njengesengezo ku-raber, upende, noketshezi lokusika ukuze udlale indima yokumelana nomlilo, ukumelana nomlilo, nokuthuthukisa ukunemba kokusika, njll.
I-4.Ingasetshenziswa futhi njenge-anticoagulant kanye ne-anti-extrusion ejenti yamafutha okugcoba.
