Saina PVC igoa igoa e masani ona faʻaaogaina tikeri polymerization poʻo faʻamatalaga faʻataʻitaʻiga.Mo se faʻataʻitaʻiga, e fitu ituaiga PVC (brand S-800, SG-7) poʻo le valu ituaiga PVC (brand S-700, SG-8) faʻatasi ai ma uiga lelei o le a faʻailoga ese e tagata gaosi oloa eseese.O le tele oi latou e fa'ailogaina i le SG ma le numera tasi e fai ma sui o fa'ata'ita'iga PVC.Ole numera o le selau ma le afe o faʻailoga e faʻatusalia ai le tikeri o le polymerization (o le numera tutusa e faʻatusalia le oloa tutusa, e pei o Qingdao Haijing HS1000, Shanghai chlor-alkali WS1000,Qilu Petrochemical S1000o fa'atusa uma e lima-ituaiga PVC).
O LE FA'AFA'ATA'IGA O LE FA'AIGA FA'ALO'OGA E FA'A'OA'O LE FA'A'OA'OGA FA'AMATALAGA E 7, 8 ITU FA'A'OGA, O LE FA'A'OA'OGA E MASANI AI O QILU PETROCHEMICAL, Shanghai CHLOR-ALKALI, CANG HUA, Qingdao HAI JING, FA'AOGA A DAGU HUA.
O nisi o paaga fou ma fiafia e ono fesili pe aisea e sili atu ai le au gaosi laupepa e faʻaaoga le ituaiga 7 ma le ituaiga 8 nai lo le ituaiga 5. E leai se isi, ae fitu, valu ituaiga PVC polymerization tikeri e maualalo, faigofie ona faʻagasolo.E le gata o laupepa, PVC paipa faʻapipiʻi, PVC valve e talafeagai foi mo le faʻaoga.
O fale gaosi paipa e masani ona faʻaaogaina le ituaiga 5. O se vaega maualuga o le calcium carbonate na faʻaopoopoina e faʻaitiitia ai tau, lea e le tatau ona faʻamatalaina iinei.
I na tausaga mataʻutia, na vaevaeina ai le PVC i lo tatou atunuu i ituaiga e valu, e taʻua o le ituaiga 1 i le 8. O uso e toʻavalu na faʻataʻitaʻiina (faʻaleagaina) e le maketi, ma na o le toafa na totoe:
Ituaiga 3(polymerization tikeri 1300, tele lava faaaogaina mo le gaosiga o uaea ma uaea, calendering ata tifaga), ituaiga 5 (polymerization tikeri 1000, tele faaaogaina mo talaaga otooto, paipa), ma le ituaiga 7 valu.
Mainstream PVC gaosiga e faʻaaoga ai le faʻamalologa metotia, i luga o le filifilia o faʻasalalauga faʻamalolo eseese, e mafai ona maua le fausaga ma le morphology o ituaiga eseese e lua o resini.
