PVC SG-8
PVC SG-8,
likhoele tsa lisebelisoa tse tala, PVC SG-8 e sebelisetsoang ho hlahisa liphanele tsa marako,
Thermoplastic high-molecular polymer e entsoeng ke ho fanyeha polymerization ea vinyl chloride monomer.Thepa ea molek'hule :- (CH2 – CHCl) n – (N: tekanyo ea polymerization, N= 590 ~ 1500).Ke thepa e tala ka ho fetisisa e sebelisoang tlhahisong ea polasetiki.E na le botsitso bo botle ba lik'hemik'hale, ho hanyetsa kutu le ho hanyetsa metsi.

Tlhaloso:
Ponahalo ea PVC SG-8 ke phofo e tšoeu e homogeneous, ntle le tatso le monko.
Tšebeliso ea mofuta oa PVC resin SG-8:
Letšoao la Resin SG-8 le sebelisoa bakeng sa tlhahiso ea libotlolo tse nang le mabota a masesaane, liphanele tsa lebota, likhoele tsa likhoele, lihlahisoa tse thata tsa sepheo se akaretsang (linoleum, letlalo la maiketsetso, lifilimi tsa polasetiki, liphutheloana tsa polymer tse tharo).
Mokhoa oa tlhahiso:
E fumanoa ka polymerization ea vinyl chloride.Polymerization e etsoa ka ho emisoa (sebakeng sa metsi).
Ho na le mekhoa e mengata ea ho hlahisa vinyl chloride ho tloha acetylene, ethylene dichloride, ethylene le ethane.Lihlahisoa tsa rona li thehiloe feela ts'ebelisong ea ethylene.
