Kev soj ntsuam ntawm Plasticizer Teeb meem kev nyab xeeb
Jun 06, 2021
Plasticizers yog ib qho tseem ceeb ntawm cov khoom siv ntxiv hauv kev ua cov yas. Tam sim no, cov yas siv los ntawm ntau dua 80 feem pua ntawm cov tuam txhab yas hauv kuv lub teb chaws yog phthalate plasticizers raws li dioctyl phthalate (DOP, los yog DEHP). Nws yog hom khoom no.
Yuav cuam tshuam ntau npaum li cas cov dej cawv yuav muaj rau DOP thiab plasticizer industries? Nws puas yuav zoo li Sanlu tainted mis hmoov tshwm sim uas ua rau lub lag luam melamine tawg rau ib pliag? Tus sau xav tias qhov no tsis zoo li. Thaum qhov teeb meem tainted mis hmoov raug nthuav tawm, nws tau txiav txim siab sai sai tias muaj tus cwj pwm ntawm kev ntxiv melamine, thiab cov txheej txheem tshawb nrhiav tsuas yog tsom rau tus cwj pwm ntawm tus kheej lossis tus cwj pwm ntawm tuam txhab; tab sis lub sij hawm no cov cawv plasticizer tshaj tus qauv, nws tseem entangled nyob rau hauv tej yam ntuj tso migration thaum lub sij hawm ntau lawm txheej txheem los yog Artificial ntxiv, thiab txiav txim los ntawm cov xov xwm tam sim no, tus qub muaj lub sab sauv tes. Qhov thib ob, nws yog tam sim no nyob rau hauv lub caij nyoog qis ntawm kev thov hauv DOP kev lag luam, thiab tus nqi nws tus kheej yog nyob rau hauv tus txheej txheem ntawm kev poob qis, thiab nws zoo nkaus li tias tsis muaj kev xav ua kom poob qis.
Txawm li cas los xij, qhov xwm txheej no tau ceeb toom rau kev lag luam plasticizer kom ua kom zoo dua cov khoom lag luam. Txawm hais tias tseem muaj qee yam ntawm cov plasticizers hauv Suav teb, phthalate plasticizers, feem ntau yog DOP, tuav txoj haujlwm tseem ceeb hauv kev ua lag luam. Phthalate plasticizers tseem muaj qhov tsis txaus ntawm ntau lub zog, tshwj xeeb tshaj yog kev nyiam huv thiab tsis muaj tshuaj lom.
Nrog rau kev nce ntawm pej xeem kev paub txog kev tiv thaiv ib puag ncig, toxicity ntawm DOP tau nyiam ntau thiab ntau dua. Hais txog qhov muaj peev xwm carcinogenic txaus ntshai ntawm DOP, lub zej zog thoob ntiaj teb tau pib siv cov kev ntsuas coj los maj mam txwv txoj kev siv DOP. Piv txwv li, US Environmental Protection Agency tau tso tseg kev lag luam ntawm 6 phthalates, tsoomfwv Swiss tau txiav txim siab txwv tsis pub siv DOP hauv cov menyuam yaus cov khoom ua si, thiab lub teb chaws Yelemees tau txwv tsis pub siv DOP hauv txhua yam khoom yas uas muaj feem xyuam rau tib neeg lub cev thiab huv. zaub mov. Nyiv kuj tau hais tias DOP raws li cov khoom siv yas yog txwv rau nws daim ntawv thov hauv cov khoom lag luam yas. Nyob rau tib lub sijhawm, cov teb chaws no tawm tswv yim txog kev siv cov plasticizers degradable thiab environmentally friendly hauv cov khoom, xws li TBC (tributyl citrate) thiab TOTM (titanate series).
Nrog rau qhov tshwm sim ntawm ib tug series ntawm zaub mov kev nyab xeeb xwm txheej uas muaj xws li plasticizers, lub domestic plasticizer kev lag luam tseem tab tom ntsib kev hloov pauv. Txog rau qhov kawg no, cov tuam txhab tsim khoom yuav tsum kho cov qauv khoom, tshem tawm cov txheej txheem ntau lawm thiab ntau yam, thiab nce kev txhim kho thiab tsim cov khoom tsis muaj tshuaj lom, pheej yig, thiab ib puag ncig zoo plasticizers. Tsoom fwv cov tuam tsev yuav tsum muaj zog txhawb kev tsim cov khoom tshiab thiab cov ntaub ntawv tshiab los ntawm kev lag luam, tshwj xeeb tshaj yog los ntawm kev txhawb nqa txoj cai, nce peev hauv kev tshawb fawb txog kev tshawb fawb, thiab txhawb cov tuam txhab kom ua tiav kev lag luam loj ntawm cov khoom lag luam zoo ib puag ncig tshiab kom sai li sai tau los ntawm kev tshawb fawb thiab thev naus laus zis. kev tshawb fawb thiab thev naus laus zis hloov pauv. Ua kom peb lub teb chaws plasticizer tshawb fawb thiab kev tsim kho thiab daim ntawv thov kom ncav cuag thoob ntiaj teb qib siab. Nyob rau tib lub sijhawm, kuv lub teb chaws yuav tsum tau hloov kho thiab txhim kho cov qauv tsim nyog ntawm cov khoom yas los txhawb cov tuam txhab tsim cov khoom lag luam uas muaj ntau dua raws li kev noj qab haus huv thiab kev tiv thaiv ib puag ncig.
Qhov xwm txheej cawv yog ceeb toom rau kev lag luam plasticizer hauv tsev, thiab nws tseem tuaj yeem pom tias yog lub sijhawm rau kev txhim kho kev lag luam. Nws tuaj yeem txhawb kev lag luam txhawm rau txhawm rau txhim kho kev ua kom zoo thiab txhim kho cov khoom lag luam thiab txhim kho hauv kev coj ntawm ntsuab, kev tiv thaiv ib puag ncig, tsis muaj tshuaj lom thiab noj qab haus huv.
