A: Property Polyvinyl chloride waa xeryahooda molecular sare polymerized by vinyl chloride monomer (VCM) oo leh curiyaha qaab dhismeedka sida CH2-CHCLn, heerka polymerization caadi ahaan sida 590-1500. In habka dib-polymerization, saameeyay noocyada arrimo sida Nidaamka polymerization, xaaladaha falcelinta, halabuurka falcelinta, wax lagu daro iwm. waxay soo saari kartaa siddeed nooc oo kala duwan oo ah waxqabadka resin PVC waa ka duwan yahay.Marka loo eego waxyaabaha hadhaaga ah ee vinyl chloride ee ku jira xabagta polyvinyl chloride, waxa loo qaybin karaa: darajo ganacsi, heerka nadaafada cuntada iyo heerka codsiga caafimaadka muuqaal ahaan, xabagta polivinyl chloride waa budo cad ama pellet.
B: Codsiga xabagta chloride polyvinyl waxaa si weyn loogu isticmaalaa soo saarista polyvinyl chloride boardy leatheroid, rinjiga iyo wakiilada koollada, tec.Rinji iyo dhejis .Qayb sida waafaqsan codsiga:
1. Qalabka dhismaha: sida tuubooyinka UPVC, tuubooyinka UPVC, guddi iyo baararka qaybta.
2.Waxyaabaha baakadka ah.
3.Alaabaha elegtarooniga ah: sida fiilooyinka elegtarooniga ah, fiilooyinka, cajaladaha xabagta iyo boolal
4.Alaabaha iyo agabka qurxinta iwm.
5.Others: leatheroid, alaabta la tuuri karo daawada, rinjiga jeermiska, iwm.
