1. PVC zaj duab xis polymer thawj zaug pib yauv ua rau thermal degradation lossis thermal oxidative degradation nyob rau hauv muaj cov pa oxygen nyob rau hauv qhov xwm txheej ntawm irradiation los ntawm cov cua sov sab nraud, ua kom muaj cov teeb meem hluav taws xob tsis haum.
2. Qhov ua tiav cov hluav taws xob sib xyaw tau tso tawm los ntawm cov nplaim polymer, sib txawv rau cov theem roj, thiab sib xyaw nrog oxygen oxygen los ntawm huab cua.
3. PVC zaj duab xis yog tiv thaiv, uas ua rau muaj nplaim hluav taws. Thaum lub sijhawm zuag, cov nplaim taws yuav raug txuas ntxiv los ntawm thermal oxidation, uas ua rau ntau cov nplaim hluav taws me me. Cov khoom siv hluav taws xob ua kom muaj hluav taws kub ntau heev thiab cov khoom siv sib txuas ua ke tau tso tawm los ntawm thaj chaw sib txuas. Cov khoom lag luam no suav nrog H2O, CO2, pa taws thiab pa roj lom (cov lus dub, CO2, HCL, HCN thiab SO2, thiab lwm yam).
4. Ib feem ntawm cov tshav kub ua los ntawm PVC zaj duab xis ua kom sib xyaw yog noj los ntawm cov khoom sib txuas thiab qhov chaw nyob ib puag ncig txias, thaum lwm feem yog txau rov qab mus rau saum npoo ntawm cov khoom siv polymer, kom cov polymer txuas ntxiv rau cov khoom siv thermal cuam tshuam thiab thermal oxidation kev ua haujlwm tsis zoo, yog li ua cov khoom txuas ntxiv tau ruaj khov thiab hloov mus rau cov nplaim hluav taws ua kom tawm tsam.
