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.
