Igama lohlobo lwePVC yaseTshayina lidla ngokusetyenziswa isidanga sepolymerization okanye imodeli yochazo.Ngokomzekelo, uhlobo olusixhenxe lwe-PVC (i-brand S-800, SG-7) okanye uhlobo olusibhozo lwe-PVC (i-brand S-700, SG-8) enomgangatho omhle iya kuphawulwa ngokwahlukileyo ngabavelisi abahlukeneyo.Uninzi lwazo luphawulwe nge-SG kunye nedijithi enye ukumela iimodeli zePVC.Inani lamakhulu kunye namawaka amanqaku amele iqondo lepolymerization (inani elifanayo limele imveliso efanayo, njengeQingdao Haijing HS1000, iShanghai chlor-alkali WS1000,Qilu Petrochemical S1000bonke bamele uhlobo ezintlanu PVC).

UTHELEKISO UKUBA UMNQA WASEKHAYA USEBENZA IZIXHOBO EZIBONAKALISAYO IPHEPHA LOKUSEBENZA ANGAPHEZULU 7, 8 IINTLOBO, YINTONI UKUSETYENZISWA NGOKUQHELEKILEYO QILU PETROCHEMICAL, Shanghai CHLOR-ALKALI, CANG HUA, Qingdao HAI JING, DAGU HUA'S PRODUCT.

Abanye amaqabane amatsha nabanomdla banokubuza ukuba kutheni abavelisi bamashidi bakhetha ukusebenzisa uhlobo lwe-7 kunye nohlobo lwesi-8 endaweni yohlobo lwesi-5. Ayikho enye, kodwa ezisixhenxe, ezisibhozo uhlobo lwe-PVC polymerization degree iphantsi, kulula ukuyiqhuba.Iphepha kuphela, izixhobo zombhobho wePVC, iivalvu zePVC nazo zifanelekile ukusetyenziswa.

Iifektri zemibhobho zihlala zisebenzisa uhlobo lwe-5. Umlinganiselo ophezulu we-calcium carbonate nawo wongezwa ukunciphisa iindleko, ezingafanele zichazwe apha.

Ngaloo minyaka yoyikekayo, iPVC yelizwe lethu yayahlulahlulwe yaziindidi ezisibhozo, ezizezi, uhlobo loku-1 ukuya kolwesi-8. Aba bazalwana basibhozo bavavanywa (baphanziswa) yimarike, kwasala abane kuphela:

Uhlobo lwesi-3(i-polymerization degree 1300, isetyenziselwa ukuvelisa i-wire kunye nentambo, ifilimu ye-calendering), uhlobo lwe-5 (i-polymerization degree 1000, isetyenziselwa kakhulu kwiiprofayili, imibhobho), kunye nohlobo lwe-7 yesibhozo.

Imveliso yePVC ephambili kusetyenziswa indlela yokunqunyanyiswa, ekukhethweni kwe-dispersant eyahlukeneyo yokumiswa, inokufumaneka ubume be-particle kunye ne-morphology yeentlobo ezimbini ze-resin.
