Polyvinyl chloride (PVC) yog cov khoom siv hluavtaws uas muaj ntau yam kev siv. Nws yog polymerized los ntawm vinyl chloride monomer nyob rau hauv sib txawv proportions thiab muaj ntau yam zoo, nrog rau corrosion kuj, nplaim retardancy, ib puag ncig tiv thaiv, ua tau yooj yim thiab tsawg tus nqi. Raws li cov khoom siv tseem ceeb, PVC yog dav siv hauv kev tsim kho, tsheb, kev kho mob, khoom siv hluav taws xob thiab lwm yam. Hauv kev tsim kho, PVC yog cov khoom siv zoo heev, feem ntau siv los ua cov kav dej thiab qhov rais thav ntawv. Vim muaj cov khoom tshwj xeeb ntawm PVC, nws tuaj yeem siv sab hauv tsev thiab sab nraum zoov thiab tuaj yeem tiv taus qhov chaw hnyav xws li kub thiab av noo. Tsis tas li ntawd, PVC kuj muaj kev tiv thaiv corrosion zoo thiab tsim nyog rau kev ua cov kav dej thiab cov tso tsheb hlau luam. Qhov no yog vim PVC muaj cov kua qaub thiab alkali tsis kam thiab tuaj yeem nyob ruaj khov hauv cov kua qaub lossis alkaline ib puag ncig. Nyob rau tib lub sijhawm, PVC kuj tuaj yeem ua tiav rau hauv cov ntaub ntawv rwb thaiv tsev thiab cov txheej txheem dej tsis zoo siv rau hauv cov ru tsev thiab cov hauv paus tsev. PVC kuj yog ib yam khoom zoo heev rau ib puag ncig. Txawm hais tias cov pa phem tuaj yeem raug tsim tawm thaum lub sijhawm tsim khoom, cov roj no tuaj yeem rov ua dua tshiab, txo qhov cuam tshuam rau ib puag ncig. PVC pov tseg kuj tseem tuaj yeem siv thiab rov siv dua, tsis txhob muaj teeb meem ntawm kev siv nyiaj pov tseg. Zuag qhia tag nrho, PVC muaj ntau qhov zoo uas ua rau nws yog cov khoom siv zoo rau ntau daim ntawv thov. Tsis tsuas yog nws tuaj yeem muab cov ntaub ntawv tseem ceeb rau peb cov kev tsim kho thiab kev lag luam, tab sis nws kuj yog ib puag ncig tus phooj ywg thiab kev lag luam.
