isicelo

Ukwakheka okuyinhloko kwezinto zekhebula le-PVC kufaka phakathi:i-polyvinyl chloride resin, i-dioctyl phthalate, i-stabilizer, i-plasticizer, i-inorganic filler, i-filler, i-lubricant, i-antioxidant, i-colorant, njll., elungiselelwe ngokuxuba nokuxova nokukhipha.

Okuqukethwe kwe-Plasticizer kuvame ukuba phakathi kuka-50PHR no-60PHR.Ngokuvamile khetha ukumelana nokushisa kanye nokusebenza kokufakwa kukagesi kwe-plasticizer enhle kakhulu ukuze kuthuthukiswe kangcono ukumelana nokushisa kungase kwengezwe ku-trioctyl metapentriacid.Izinhlobonhlobo zamapulasitiki ezisetshenziswa ndawonye ngokuvamile ziba nomphumela omuhle kakhulu.Eqinisweni, ama-plasticizers kufomula yezinto zekhebula le-PVC nawo asetshenziswa ndawonye.Izinto zekhebula le-PVC ezinokuvaleka okuqinile zingakhetha i-phosphate ester njenge-ejenti eyinhloko, kanye ne-benzoate ester njenge-ejenti eyinhloko ifanele ibanga elivamile.Ukumelana nokushisa nokumelana okuguquguqukayo kwe-plasticizer yizici ezinqumayo zokumelana nokushisa okuphezulu kwezinto zekhebula.
