PVC SG-8
PVC SG-8,
tambo ducts mbishi zvinhu, PVC SG-8 inoshandiswa kugadzira mapaneru emadziro,
Iyo thermoplastic yakakwira-molecular polymer yakagadzirwa nekumiswa kwepolymerization yevinyl chloride monomer.The molecular formula :- (CH2 – CHCl) n – (N: dhigirii repolymerization, N= 590 ~ 1500).Ndiyo yakanyanya kuwanda mbishi inoshandiswa mukugadzirwa kwepurasitiki.Iine kugadzikana kwakanaka kwekemikari, kusagadzikana kwekuora uye kusagadzikana kwemvura.

Applications
Polyvinyl chloride resin ine zvakasiyana-siyana zvekushandisa, zvakadai semotokari yemukati, midziyo yekushongedza yemhuri, kushambadzira chiedza bhokisi, shangu, PVC pombi uye fittings, PVC profiles uye hose, PVC sheet uye ndiro, rolling firimu, inflatable matoyi, kunze zvigadzirwa, PVC waya uye tambo, PVC chakagadzirwa dehwe, huni uye epurasitiki pasi, maranga bhodhi, etc.
Packaging
25kg craft bag liner ine PE
Tsanangudzo:
Chitarisiko PVC SG-8 ihomogeneous chena poda, isina kuravira uye kunhuwa.
Kushandiswa kwePVC resin brand SG-8:
Resin brand SG-8 inoshandiswa kugadzira yakatetepa-yakavezwa profiled moldings, madziro mapaneru, tambo ducts, semi-yakaomesesa zvigadzirwa zveGeneral chinangwa (linoleum, ganda rekugadzira, mafirimu epurasitiki, matatu-dimensional polymer packaging).
Nzira yekugadzira:
Inowanikwa ne polymerization yevinyl chloride.Iyo polymerization inoitwa mukumiswa (munzvimbo yemvura).
Kune nzira dzakawanda dzekugadzira vinyl chloride kubva kuacetylene, ethylene dichloride, ethylene uye ethane.Zvigadzirwa zvedu zvinongobva pakushandiswa kwe ethylene.
