Qhov sib txawv tseem ceeb ntawm cov khoom siv raw ntawm PVC plastics thiab cov khoom siv rov ua dua tshiab yog: cov khoom tsim los ntawm cov khoom siv raw ntawm PVC yas granules feem ntau tsis muaj xim thiab tsis muaj ntxhiab, nrog cov luster zoo, elasticity zoo, muag muag heev, thiab qhov tseem ceeb tshaj plaws yog kev nyiam huv. thiab kev nyab xeeb. ; Cov khoom siv rov ua dua yog yaj thiab rov ua dua, thiab cov khoom siv raw yog siv rau lub sijhawm. Thaum lub sij hawm tus txheej txheem no, lub cev lub cev ntawm PVC xws li hardness thiab yooj yuav txo qis. Cov khoom siv raw ntawm PVC yas pellets muaj cov khoom siv zoo xws li lub zog tensile thiab zoo tiv thaiv kev laus; Cov khoom siv rov ua dua tshiab yog siv dua tshiab thiab rov ua dua tshiab, thiab tus nqi qis heev. Kev tsim cov khoom siv raw ntawm PVC yas pellets yog tswj tau, thiab cov ntsiab lus ntawm cov hlau hnyav tuaj yeem tswj tau nruj me ntsis nyob rau hauv qhov ntau teev los ntawm kev lag luam; thaum cov khoom siv rov ua dua tshiab tuaj yeem muaj cov khoom txwv tsis pub siv (xws li txhuas vim tias qhov chaw ntawm cov khoom siv tsis paub meej), cadmium) tshaj tus qauv. Cov khoom siv raw ntawm PVC yas granules yog thawj xim ntawm PVC, uas tuaj yeem hloov kho rau cov xim uas xav tau nrog toner; thaum cov khoom siv rov ua dua yog qhov nyuaj rau kev hloov pauv hauv cov txheej txheem xim vim muaj ntau yam ntawm cov khoom siv xim.
