Toxicity
Lwm qhov kev txhawj xeeb nrog PVC boards yog lawv cov tshuaj lom. PVC boards muaj ntau yam tshuaj, xws li phthalates, cadmium, lead, thiab dioxins, uas paub tias yuav ua rau tib neeg noj qab haus huv. Cov tshuaj no tuaj yeem ua rau muaj ntau yam teebmeem kev noj qab haus huv, suav nrog teeb meem ua pa, mob hlwb, thiab txawm tias mob qog noj ntshav.
Ntxiv mus, raug rau cov tshuaj no tuaj yeem tshwm sim thaum lub sijhawm tsim khoom lossis los ntawm kev sib cuag nrog PVC boards uas tau teeb tsa hauv tsev. Piv txwv li, yog tias PVC boards tsis raug kaw los yog pleev xim rau, lawv tuaj yeem tso cov pa phem rau hauv huab cua, ua rau muaj kev pheej hmoo rau huab cua hauv tsev thiab kev noj qab haus huv ntawm tib neeg.
Tsis muaj Recyclability
Thaum kawg, PVC boards tsis yog rov ua dua tshiab, uas ua rau lawv qhov kev cuam tshuam ib puag ncig. Thaum PVC boards tsis siv lawm, lawv dhau los ua cov khoom pov tseg, uas tuaj yeem siv ntau pua xyoo los decompose hauv cov chaw pov tseg. Qhov tsis muaj peev xwm rov ua dua PVC boards kuj txhais tau hais tias lawv tsis tuaj yeem siv los tsim cov khoom tshiab, ua rau muaj kev xav tau ntawm PVC boards tshiab thiab ua rau muaj kev cuam tshuam ib puag ncig ntawm lawv cov khoom.
Xaus
Hauv kev xaus, PVC boards yog cov khoom siv dav siv rau kev tsim kho thiab muaj qee qhov txiaj ntsig zoo, suav nrog kev ua haujlwm ntev thiab pheej yig. Txawm li cas los xij, qhov tsis zoo ntawm PVC boards yuav tsum tsis txhob saib xyuas, tshwj xeeb tshaj yog lawv cov kev cuam tshuam ib puag ncig, toxicity, thiab tsis muaj kev rov ua dua tshiab.
Txhawm rau txo qhov cuam tshuam tsis zoo ntawm PVC boards, cov neeg tsim khoom thiab cov neeg muaj feem cuam tshuam yuav tsum xav txog lwm cov ntaub ntawv uas muaj kev ruaj khov thiab zoo ib puag ncig. Tsis tas li ntawd, cov txheej txheem pov tseg kom raug rau PVC boards yuav tsum tau siv los tiv thaiv kev tso tawm cov tshuaj lom neeg rau hauv ib puag ncig. Zuag qhia tag nrho, kev paub txog qhov tsis zoo ntawm PVC boards yog qhov tseem ceeb rau kev tsim kom muaj kev lag luam ruaj khov thiab ib puag ncig kev lag luam.
