Iparafini enechlorine lulwelo olumthubi olubugolide okanye olu-amber viscous, olungatshiyo, aluqhushumbisi, kwaye luphantsi ngokugqithisileyo. I-Soluble kwi-solvents ezininzi ze-organic, ezinganyibilikiyo emanzini kunye ne-ethanol. Xa ishushubezwa ukuya kutsho ngaphezulu kwe-120℃, iya kubola ngokucothayo kwaye inokukhulula igesi yehydrogen chloride. Kwaye iioksidi zentsimbi, i-zinc, kunye nezinye iintsimbi ziya kukhuthaza ukubola kwayo. Iparafini ene-chlorine yi-plasticizer encedisayo kwi-polyvinyl chloride. Ukuguquguquka okuphantsi, okungatshiyo, ukuvumba. Le mveliso ithatha indawo ye-plasticizer ephambili, enokunciphisa iindleko zemveliso kunye nokunciphisa ukutsha.
Iimbonakalo
Ukusebenza kweplastiki yeparafini ekloriniwe 52 ingaphantsi kuneplasticizer ephambili, kodwa inokunyusa ukufakwa kombane kunye nokumelana nomlilo kwaye inokuphucula amandla okuqina. Ukungalungi kweparafini ekloriniwe 52 kukuba ukumelana nokuguga kunye nokumelana nobushushu obuphantsi kubi, isiphumo sokuphinda sisetyenziswe kwakhona sibi, kwaye i-viscosity iphezulu. Nangona kunjalo, phantsi kwemeko yokuba eyona plasticizer inqongophele kwaye iyabiza, iparafini ekloriniwe 52 isathatha indawo yentengiso.
Iparafini ye-chlorinated 52 inokuxutywa kunye nezinto ezinxulumene ne-ester, inokwenza i-plasticizer emva kokuxuba. Ukongeza, ikwaneempawu zokunqanda amadangatye kunye nokuthambisa. Ukuba kuyimfuneko, inokudlala indima kwi-antisepsis.
Umthamo wemveliso yeparafini ekloriniwe 52 yomelele kakhulu. Kwinkqubo yesicelo, ngokukodwa sebenzisa indlela ye-thermal chlorination kunye ne-catalytic chlorination method. Kwiimeko ezikhethekileyo, iindlela ze-photochlorination nazo zisetyenziswa.
Isicelo
I-1.I-parafini ye-chlorine 52 ayinyibiliki emanzini, ngoko ke ingasetyenziselwa ukuzalisa kwiingubo zokunciphisa iindleko, ukunyusa iindleko ezingabizi kakhulu kunye nezakhiwo ezingenamanzi kunye nomlilo.
I-2.Isetyenziswe kwiimveliso ze-PVC njenge-plasticizer okanye i-plasticizer encedisayo, ukuhambelana kwayo kunye nokumelana nobushushu kungcono kune-parafini ye-chlorinated-42.
I-3.Inokuthi isetyenziswe njengesongezo kwi-rubber, ipeyinti, kunye nokusika i-fluid ukudlala indima yokumelana nomlilo, ukumelana nomlilo, kunye nokuphucula ukuchaneka kokusika, njl.
I-4.Inokuthi isetyenziswe njenge-anticoagulant kunye ne-anti-extrusion agent ye-lubricating oils.
