Polyvinyl chloride ọkpọkọ, na-azọrọkwa pvc ọkpọkọ, bụ tubing na thermal plasticity high polymer na-mere site polymerization nke vinyl choride monomer, were polyvinyl chloride (PVC) RESINS dị ka isi akụrụngwa, tinye kwesịrị ekwesị na-egbochi ịka nká, ihe na-edozi onye na-edozi ihe. wdg, ihe na-akpụ site na usoro dị ka ịgwakọta, calendering, agụụ formings.

Pvc ọkpọkọ na-eguzogide corrosion siri ike, ọ na-ejikọta na ọ dị mfe, PVC nwere ike ime ka oxygenant, reductive agent na acid siri ike.Ma ọ nwere ike imebi ya na oge na-adịghị mma na-akpọtụrụ na aromatic hydrocarbon, chlorinated hydrocarbon dị ka vitriol. mmanụ, nitric acid gbadoro anya site na nnukwu oxidizing acid.

Ma, pvc ọkpọkọ, karịsịa UPVC ọkpọkọ iguzogide toheat bụ ogbenye, na gburugburu ebe obibi ike na-ebelata karịa 60 ℃, na n'okpuru ala okpomọkụ gburugburu ebe obibi, Vybak mmiri ịse iguzogide mmetụta ujo ebelata.Na njem, echichi na ojiji usoro, mfe e nwere kenkuwa. mgbawa;Tụkwasị na nke ahụ, arụmọrụ nke pvc pipe na-eguzogide ihe mgbagwoju anya dịkwa njọ.
