Cov khoom siv twg yog PVC yas? PVC yog cov hmoov dawb nrog cov qauv amorphous, tseem hu ua polyvinyl chloride. PVC khoom yog lub teeb nyob rau hauv qhov hnyav, tsis-flammable, anti-corrosion, non-toxic, insulating thiab lwm yam khoom, tab sis nws tsis yog kub-resistant rau kub thiab lub teeb. Yog li ntawd, nws yog ib qho tsim nyog los hloov kho thiab txhim kho nws cov kev ua tau zoo los ntawm kev ntxiv ntau yam khoom siv los tsim cov khoom siv ua tiav PVC, uas tuaj yeem muab rau cov lag luam uas ua cov khoom tiav PVC. PVC yas yog tsuas yog ua los ntawm PVC resin hmoov, ntxiv plasticizers, lubricants, oxidants, tougheners, fillers thiab pigments thiab lwm yam khoom pab. Lub cev muaj zog ntawm PVC yas hais yog muab faib ua mos thiab tawv. Cov mos PVC yas hais yuav tsum muaj stabilizers, plasticizers, lubricants thiab lwm yam auxiliary cov ntaub ntawv los txhim kho cov fluidity thiab hardness ntawm cov khoom. Cov tawv PVC yas hais yeej tsis muaj Plasticized. Yog tias tsis muaj kev hloov kho kev nplua nuj, nws nyuaj rau tsim cov khoom tsim nyog ib nrab ua tiav PVC yas granules.
