Ubushinwa izina rya PVC mubusanzwe rikoreshwa murwego rwa polymerisation cyangwa kwerekana icyitegererezo.Kurugero, ubwoko burindwi bwa PVC (ikirango S-800, SG-7) cyangwa ubwoko umunani bwa PVC (ikirango S-700, SG-8) bufite ubuziranenge buzarangwa muburyo butandukanye nababikora batandukanye.Benshi muribo barangwa na SG numubare umwe kugirango uhagararire moderi ya PVC.Umubare w'amajana n'ibihumbi byerekana urwego rwa polymerisation (umubare umwe ugereranya ibicuruzwa bimwe, nka Qingdao Haijing HS1000, Shanghai chlor-alkali WS1000,Qilu Ibikomoka kuri peteroli S1000byose byerekana ubwoko butanu bwa PVC).

Gereranya NUKO AKARERE KA DOMESTIQUE AKORESHEJE URUPAPURO RW'IMPAKA ZIKORESHEJWE BIKORESHEJWE BYINSHI 7, 8

Bamwe mubafatanyabikorwa bashya kandi bashimishijwe barashobora kubaza impamvu abakora impapuro bahitamo gukoresha Ubwoko 7 hanyuma bakandika ubwoko bwa 8 aho gukoresha ubwoko bwa 5. Ntayindi, ariko irindwi, umunani ubwoko bwa PVC polymerisation ni buke, byoroshye gutunganya.Ntabwo ari urupapuro gusa, ibyuma bya PVC, ibyuma bya PVC nabyo birakwiriye gukoreshwa.

Uruganda rukora imiyoboro rusanzwe rukoresha ubwoko bwa 5. Umubare munini wa calcium karubone nayo wongeyeho kugirango ugabanye ibiciro, bitagomba gusobanurwa hano.

Muri iyo myaka iteye ubwoba, PVC mugihugu cyacu yagabanijwemo ubwoko umunani, aribwo bwoko bwa 1 kugeza kuri 8. Abavandimwe umunani barageragejwe (barimbuwe) nisoko, hasigaye bane gusa:

Andika 3.

Ibikorwa byingenzi bya PVC ukoresheje uburyo bwo guhagarika, kubijyanye no gutoranya ibintu bitandukanye byo guhagarika, birashobora kuboneka imiterere yimiterere na morphologie yubwoko bubiri bwa resin.
