PVC rau cov kav dej, PVC Yeeb Nkab Raw Khoom, PVC cob rau Hose, PVC cob rau irrigation,
Polyvinyl Chloride (PVC) yog linear thermoplastic cob ua los ntawm polymerization ntawm vinyl chloride monomer.Vim yog qhov sib txawv ntawm cov khoom siv raw, muaj ob txoj hauv kev ntawm kev sib xyaw vinyl chloride monomer calcium carbide txheej txheem thiab cov txheej txheem roj av.Sinopec PVC tau txais ob txoj kev raug ncua, raws li Japanese Shin-Etsu Chemical Company thiab American Oxy Vinyls Company.Cov khoom muaj cov tshuaj zoo corrosion kuj, zoo heev hluav taws xob rwb thaiv tsev khoom thiab zoo tshuaj stability.Nrog cov ntsiab lus chlorine siab, cov khoom siv muaj hluav taws kub zoo thiab tua tus kheej.PVC yog yooj yim rau txheej txheem los ntawm extrusion, txhaj tshuaj molding, calendering, tshuab moulding, compressing, cam khwb cia molding thiab thermal molding, thiab lwm yam.
Daim ntawv thov
PVC yog ib qho ntawm cov khoom siv thermoplastic feem ntau siv.Nws tuaj yeem siv los ua cov khoom lag luam nrog lub siab tawv thiab lub zog, xws li cov kav dej thiab fittings, profiled qhov rooj, qhov rais thiab cov ntawv ntim.
Nws tseem tuaj yeem ua cov khoom muag muag, xws li cov yeeb yaj kiab, cov ntawv txheeb, cov xaim hluav taws xob thiab cov cables, cov ntaub pua tsev thiab cov tawv hluavtaws, los ntawm kev ntxiv cov yas yas.
