PVC material, uas tseem hu ua polivinyl chloride, yog ib qho plastic uas tau siv rau hauv ntau yam khoom uas peb siv hauv kev daily. Nws yog nyuaj, muaj qhov pheej yig, thiab tuaj yeem sau rau hauv ntau yam li no thiab ntau yam duab. Vim tias nws muaj cov lus qhia no, PVC tau siv rau hauv ntau yam kev sib tham. Nej pom nws rau hauv cov tub nrog, cov nplooj ntawv, thiab cov khoom siv rau hauv tsev. Peb lub tsev khoob, Maijisen, nyob rau hauv kev tsim cov khoom PVC, ua kom lawv zoo thiab sib xws rau kev xav tau ntawm cov neeg siv khoom. Cov khoom no tau siv ntau vim nws pheej yig rau kev siv thiab nyuaj rau ntev.
PVC tsis tuaj yeem tshuav rau ntau yam kev lag luam rau cov lus txhais li cas. Thaum kawg, nws yog qhov tsis muaj nqi siab heev. Cov khoom sib thaj tuaj yeem tsim los ntawm PVC thiab tsis muaj nqi siab heev. Qhov nqi siab no yog qhov tseem ceeb rau cov khoom sib thaj uas xav sau nqi thiab tso cai rau qhov zoo. Lwm qhov tseem ceeb yog nws lub cev nyob rau hauv qhov chaw twg. PVC tau siv rau kev kho tshuaj, kev pab cuam tshuaj, thiab kev siv ntawv. Piv txwv li, rau kev kho tshuaj, PVC cov tub yog siv rau kev kho tshuaj vim nws tsis muaj qhov tshuaj thiab tuaj yeem tshuaj rau qhov tshuaj ntau. Rau kev pab cuam tshuaj, nws tau siv rau kev tsim cov kab mob thiab cov tub pab cuam tshuaj vim nws yog qhov tshuaj thiab tsis muaj kev puas tsuaj rau neeg. Nws kuj tuaj yeem tsim rau cov kab tshuaj, yog li cov neeg tsim khoom tuaj yeem tsim cov khoom tshwj xeeb. Ntxiv rau ntawd, PVC tsis muaj kev puas tsuaj los ntawm cov tshuaj thiab qhov roj, yog li nws zoo rau kev siv hauv tsev. Qhov no txhais tau tias cov khoom PVC tuaj yeem tshuaj rau qhov roj, qhov sov, thiab cov tshuaj tshwj xeeb uas tsis muaj kev puas tsuaj. Thaum kawg, PVC tuaj yeem siv dua, thiab qhov no yog qhov tseem ceeb heev tam sim no. Cov khoom sib thaj xav muaj kev siv tshwj xeeb uas zoo rau lub zog thiab PVC tuaj yeem pab txo cov khoom tsis muaj kev siv. Yog li cov lus no yog qhov uas ua rau cov kev lag luam xaiv PVC rau qhov tseem ceeb. Piv txwv li, peb Lub wax polyethylene uas tau muab ua kom zoo rau lub ntiaj teb (OPE Wax) yog qhov piv txwv zoo rau qhov kev siv tshwj xeeb rau kev tsim PVC.
