Txawm hais tias PVC hais lawv tus kheej tsis muaj tshuaj lom, lawv tuaj yeem tso cov tshuaj lom nyob rau hauv qee yam mob.
Hloov los ntawm Additives ntawm Toxicity ntawm PVC Particles
PVC hais, raws li ib yam ntawm cov khoom siv polymer feem ntau yog ntxiv nrog ntau yam additives hauv cov txheej txheem ntawm kev tsim khoom los txhim kho lawv cov kev ua tau zoo. Cov tshuaj ntxiv no tuaj yeem ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.
Plasticizer: Plasticizer yog ib qho ntawm cov khoom siv feem ntau siv hauv cov khoom siv PVC. Nws tuaj yeem ua cov ntaub ntawv PVC mos thiab yooj yim rau kev ua. Txawm li cas los xij, qee hom plasticizers, xws li phthalates, raug suav hais tias muaj kev cuam tshuam tsis zoo rau kev ua me nyuam, kab mob endocrine, thiab lwm yam tib neeg lub cev. Yog li ntawd, thaum xaiv cov khoom siv PVC, sim xaiv cov khoom uas tsis muaj los yog muaj cov yas uas tsis muaj tshuaj lom.
Stabilizer: Nws yog txoj hauv kev los txhim kho cov cua sov thiab lub teeb ruaj khov rau cov ntaub ntawv PVC. Nco ntsoov tias qee cov stabilizers muaj cov hlau hnyav, xws li cov hlau lead uas yuav muaj kev phom sij rau kev noj qab haus huv. PVC uas muaj cov tshuaj lom neeg ua kom ruaj khov yuav tsum tsis txhob siv rau hauv cov khoom ntim khoom noj.
Cov kev ceev faj yuav tsum tau coj mus rau hauv kev sib raug zoo nrog PVC cov khoom siv, thaum txo qis qhov txaus ntshai lawv tuaj yeem sawv cev yog:

Zam Kev Kub Kub Kub: Tsis txhob siv cov khoom yas xws li PVC uas yuav tiv thaiv cov khoom tsis zoo los ntawm kev tso tawm zoo dua, lossis nws yuav hloov zuj zus ntxiv rau qhov kub thiab txias nyob rau lub sijhawm ntev.
Cov Lus Cim Cia: Muab tso rau hauv qhov chaw txias, qhuav thiab airy qhov chaw PVC cov khoom yuav tsum tau muab tso rau ntawm qhov hluav taws kub.
Kev pov tseg pov tseg: Nyob rau hauv cov ntaub ntawv ntawm cov khoom pov tseg PVC, incineration yuav tsum tau zam thiab ntau tus phooj ywg ib puag ncig (recycling los yog landfill) xaiv.
