PVC xabagta SG5 K qiimaha 66-68 Polyvinyl chloride
Astaamaha
PVC caag ah "polyvinyl chloride caag", waa budo cad, alaabta inta badan lagu sameeyay by polymerization of vinyl chloride monomer, oo ku dar walxaha kale si kor loogu qaado caabbinta kulaylka alaabta, adkaanta iyo ductility Ka-hortagga daxalka, xooggan oo waara, sidoo kale iska caabin dab (Qiimaha Ololka ≥40), iska caabin kiimikaad sare leh (90% sulfuric acid, fiirsashada nitric acid 60% iyo riwaayad Sodium hydroxide 20%), xoog farsamo oo heer sare ah iyo dahaarka wanaagsan. Laakiin iska caabbinta iftiinka iyo iska caabbinta kulaylku waa wax yar oo xun (goob jilicsan 80 ℃, haddii heerkulku ka badan yahay 130 ℃, midabku wuu beddeli doonaa oo soo baxaya HCI), Markaa waa inaan ku darnaa xasiliye si loo hagaajiyo caabbinta iftiinka iyo iska caabinta kulaylka marka la isticmaalo.
