Polyvinyl Chloride (PVC) xabagta tuubada,
PVC ee tuubada dheecaanka, Alaabta ceeriin ee tuubada PVC, Xabagta PVC ee Hose, Xabagta PVC ee waraabka,
Polyvinyl Chloride (PVC) waa xabagta heerkulbeegga toosan ee uu soo saaray polymerization monomer vinyl chloride.Sababo la xiriira kala duwanaanshaha alaabta ceeriin, waxaa jira laba hab oo lagu farsameeyo vinyl chloride monomer calcium carbide habka iyo habka batroolka.Sinopec PVC waxay qabataa laba hab oo ka joojinta, siday u kala horreeyaan Shirkadda Kiimikada Shin-Etsu ee Japan iyo Shirkadda American Oxy Vinyls.Alaabtu waxay leedahay iska caabin daxalka kiimikaad oo wanaagsan, hanti dahaarka korantada oo aad u wanaagsan iyo xasilooni kiimikaad oo wanaagsan.Iyada oo ay ku jirto maadada koloriin sare, maaddadu waxay leedahay dab-demis wanaagsan iyo sifooyin is-deminta.PVC way fududahay in lagu farsameeyo extrusion, qaabaynta duritaanka, calendering, dharbaaxada, isku-buufinta, qaabaynta kabka iyo qaabaynta kulaylka, iwm.
Codsiga
PVC waa mid ka mid ah resins thermoplastic ee ugu isticmaalka badan.Waxaa loo isticmaali karaa in lagu sameeyo alaab adag oo adag, sida tuubooyinka iyo qalabka wax lagu dhejiyo, albaabada muuqaalkooda leh, daaqadaha iyo baakadaha.
Waxa kale oo ay samayn kartaa alaabo jilicsan, sida filimada, xaashida, fiilooyinka korantada iyo fiilooyinka, sagxadaha sagxadaha iyo maqaarka synthetic, iyada oo lagu daro caagadaha.
