Dab tsi tsis ntseeg tau ntsib cov khoom siv PVC?

Cov ntaub ntawv PVC tau ntsib kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv thaum lawv thawj zaug tawm. Ua ntej tshaj plaws, cov txheej txheem tsim khoom ntawm PVC yuav tso cov tshuaj chlorine thiab olefins, uas yuav muaj kev cuam tshuam rau ib puag ncig. Qhov thib ob, cov khoom siv PVC tseem yuav tso tawm cov tshuaj tsis haum cov organic thiab cov carcinogens thaum siv, ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv. Tsis tas li ntawd, qhov degradability ntawm cov ntaub ntawv PVC kuj tau raug thuam, thiab kev siv mus ntev thiab pov tseg yuav ua rau muaj kev kub ntxhov ntau dua rau ib puag ncig. Hauv kev teb rau cov teeb meem no, tib neeg tau maj mam ntsuas xws li kev txhim kho cov txheej txheem tsim khoom, txhim kho thev naus laus zis thiab ntxiv dag zog rau kev saib xyuas ib puag ncig, thiab maj mam daws qhov tsis ntseeg txog cov khoom siv PVC.

Cov kev ntsuas muaj xws li:
1. Txhim kho cov txheej txheem tsim khoom: Txo cov emission ntawm cov khoom tsis zoo thiab txo qhov cuam tshuam rau ib puag ncig los ntawm kev ua kom zoo ntawm cov txheej txheem ntau lawm.
2. Kev txhim kho thev naus laus zis: Tsim cov khoom siv PVC tshiab los ua kom lawv ib puag ncig zoo thiab noj qab nyob zoo, xws li siv cov khoom siv ntxiv rau ib puag ncig thiab lwm yam khoom siv.
3. Txhim khu kev saib xyuas ib puag ncig: xyuas kom muaj kev cuam tshuam rau ib puag ncig thaum lub sijhawm tsim khoom thiab siv cov ntaub ntawv PVC raug txo qis los ntawm kev tsim cov qauv nruj dua ib puag ncig thiab kev tswj xyuas.
4. Txhim kho tus nqi rov ua dua ntawm PVC pov tseg: Los ntawm kev rov ua dua thiab rov siv dua PVC pov tseg, qhov cuam tshuam rau ib puag ncig tuaj yeem txo thiab cov nqi khoom kuj tuaj yeem txo.
5. Txhawb kev txhim kho kom ruaj khov thiab siv cov ntaub ntawv PVC: Txhawb kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov los ntawm kev txhawb nqa kev siv cov khoom siv PVC ruaj khov, xws li biomass-raws li PVC cov ntaub ntawv, cov khoom siv PVC, thiab lwm yam.
