PVC SG-8
PVC SG-8,
cable ducts raw khoom, PVC SG-8 siv rau kev tsim cov phab ntsa panels,
Lub thermoplastic high-molecular polymer ua los ntawm kev ncua polymerization ntawm vinyl chloride monomer.Cov mis mos molecular:- (CH2 - CHCl) n - (N: degree ntawm polymerization, N = 590 ~ 1500).Nws yog cov khoom siv dav dav siv hauv kev tsim khoom yas.Nws muaj kev ruaj ntseg tshuaj zoo, corrosion kuj thiab dej tsis kam.

Nqe lus piav qhia:
Puab PVC SG-8 yog homogeneous dawb hmoov, tsis muaj saj thiab tsw.
Kev siv ntawm PVC cob hom SG-8:
Resin hom SG-8 yog siv rau kev tsim cov txheej txheem nyias-walled moldings, phab ntsa panels, cable ducts, semi-rigid khoom ntawm lub hom phiaj dav dav (linoleum, tawv tawv, plasticized films, peb-dimensional polymer ntim).
Txoj kev tsim khoom:
Tau los ntawm polymerization ntawm vinyl chloride.Lub polymerization yog nqa tawm hauv kev ncua (hauv dej ib puag ncig).
Muaj ntau txoj hauv kev tsim cov yas chloride los ntawm acetylene, ethylene dichloride, ethylene thiab ethane.Peb cov khoom tsuas yog siv los ntawm kev siv ethylene.
