PVC qhov tseeb yog ib hom vinyl polymer, thiab nws cov khoom yog ib hom ntawm cov khoom siv tsis muaj hliv. Kev ruaj khov, roj nplua nyeem, cov koomhaum pabcuam kev ua haujlwm, xim, tiv thaiv tus neeg sawv cev tiv thaiv kab mob thiab lwm yam ntxiv tau ntxiv rau PVC cov ntaub ntawv hauv kev siv tiag. Nws yog nonflammability, siab zog, huab cua tsis kam thiab zoo heev geometric stability. PVC muaj muaj zog tiv taus oxidant, reductant thiab muaj zog acid. Txawm li cas los xij, nws tuaj yeem kho tau los ntawm cov tshuaj oxidizing acid, xws li muaj cov sulfuric acid thiab concentrated nitric acid, thiab nws tsis tsim nyog rau kev sib cuag nrog uas muaj ntxhiab hydrocarbon thiab chlorinated hydrocarbon.
PE, nrog tag nrho lub npe ntawm polyyetylene, yog qhov yooj yim tshaj plaws polymer organic compound. Tam sim no, nws yog qhov feem ntau siv ntaub polymer nyob hauv lub ntiaj teb. Nws yog polymerized los ntawm ethylene. Nws tuaj yeem muab faib ua high-ntom polyethylene, nruab nrab ntom polyethylene thiab ntom ntom polyethylene raws li qhov sib txawv.
Nta: PE yog mos thiab xav tau waxy. Piv nrog tus qub yas, nws yog qhov pom thiab pob tshab. Lub nplaim taws yog xiav thaum hlawv.
