Nyob rau hauv xyoo tas los no, titanium dioxide tau dhau los ua lub ntsiab lus kub hauv kev sib tham txog kev nyab xeeb ntawm cov khoom noj thiab cov khoom muaj pob tshab. Raws li cov neeg siv khoom paub ntau ntxiv txog dab tsi hauv lawv cov zaub mov, muaj cov titanium dioxide ua rau muaj kev txhawj xeeb. Cov xov xwm no yog tsom rau kev pom kev nyab xeeb, kev siv, thiab kev tsis sib haum xeeb nyob ib puag ncig qhov chaw no thaum hais txog lub luag haujlwm ntawm cov thawj coj hauv kev lag luam xws li Coolway hauv kev tsim cov titanium dioxide zoo.
Dab tsi yog titanium dioxide?
Titanium dioxide TiO2yog ib qho ntxhia ntuj siv dav hauv ntau yam lag luam xws li zaub mov, tshuaj pleev ib ce thiab pleev xim. Hauv kev lag luam khoom noj khoom haus, nws feem ntau yog siv los ua tus neeg sawv cev dawb thiab feem ntau pom muaj nyob rau hauv cov khoom xws li khoom qab zib, khoom ci, thiab khoom noj siv mis. Nws lub peev xwm los txhim kho qhov pom kev pom ntawm cov khoom noj khoom haus ua rau nws muaj kev xaiv nrov ntawm cov tuam ntxhab.
Lus Nug Kev Ruaj Ntseg
Kev nyab xeeb ntawm titanium dioxide hauv cov zaub mov tau yog ib qho kev sib cav. Cov koom haum tswj hwm xws li US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA) txiav txim siab titanium dioxide muaj kev nyab xeeb thaum noj me me. Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no tau ua rau muaj kev txhawj xeeb txog nws txoj kev pheej hmoo ntawm kev noj qab haus huv, tshwj xeeb tshaj yog thaum noj hauv daim ntawv nanoparticle. Qee cov kws tshawb fawb ntseeg tias cov nanoparticles no tuaj yeem sib sau hauv lub cev thiab ua rau muaj kev phom sij rau kev noj qab haus huv.
Txawm hais tias muaj kev txhawj xeeb no, ntau lub tuam txhab ua zaub mov txuas ntxiv mussiv titanium dioxide, hais txog nws txoj kev ua tau zoo thiab qhov tsis muaj pov thawj tseeb txuas nws mus rau cov teeb meem kev noj qab haus huv loj. Raws li qhov tshwm sim, cov neeg siv khoom yuav tsum taug qab cov ntaub ntawv nyuaj thiab kev xav.
Siv hauv kev lag luam zaub mov
Titanium dioxide yog ntau tshaj li cov khoom noj khoom haus ntxiv; nws muaj ntau daim ntawv thov hauv ntau qhov chaw. Hauv kev lag luam khoom noj nws yog tsuas yog siv rau nws cov khoom ua kom tawv nqaij, tab sis kuj yog siv los ua cov stabilizer thiab cov tshuaj tiv thaiv kab mob. Ntxiv nrog rau cov zaub mov, titanium dioxide tseem ceeb heev hauv kev tsim cov xim, txheej thiab cov yas, qhov uas nws muab opacity thiab ci.
Ib daim ntawv tshwj xeeb ntawm titanium dioxide yog cov tshuaj fiber ntau qib titanium dioxide tsim los ntawm kev siv tshuab ntau lawm. Cov tuam txhab xws li Kewei pioneered cov txheej txheem no, xyuas kom meej tias lawv cov khoom ua tau raws li cov kev xav tau tshwj xeeb ntawm domestic chemical fiber manufacturers. Nrog rau cov cuab yeej tsim khoom hauv lub xeev thiab kev cog lus kom zoo, Kewei tau dhau los ua tus thawj coj hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov titanium dioxide sulfate.
Controversy thiab Consumer Awareness
Kev tsis sib haum xeeb nyob ib puag ncigtitanium dioxidefeem ntau stems los ntawm nws cov kev faib ua zaub mov additive. Txawm hais tias qee tus ntseeg tias nws txhim kho cov zaub mov zoo, lwm tus ntseeg tias nws siv yuav tsum tau txo qis lossis tshem tawm tag nrho. Txoj kev loj hlob mus rau kev noj zaub mov huv thiab cov khoom xyaw ntuj tau ua rau ntau tus neeg siv khoom nrhiav lwm txoj hauv kev rau cov khoom siv hluavtaws, ua rau cov neeg tsim khoom noj kom rov xav txog lawv cov npe khoom.
Raws li cov neeg siv khoom paub ntau ntxiv, yog li xav tau kom pom tseeb hauv cov ntawv cim zaub mov. Ntau tus neeg tawm tswv yim rau cov kev cai kom pom tseeb ntawm kev siv titanium dioxide thiab lwm yam tshuaj ntxiv, thawb rau kev tshawb fawb ntxiv kom nkag siab txog lawv cov txiaj ntsig kev noj qab haus huv mus ntev.
nyob rau hauv xaus
Qhov tseeb txogtitanium dioxide hauv cov khoom nojyog complex, nrog rau nws txoj kev nyab xeeb, kev siv thiab kev sib cav tsis tu ncua. Thaum cov neeg tswj hwm xav tias nws muaj kev nyab xeeb rau kev noj, kev paub txog cov neeg siv khoom ntau ntxiv thiab kev thov kom pom tseeb tau ua rau muaj kev sib tham tseem ceeb txog nws lub luag haujlwm hauv peb cov khoom noj. Cov tuam txhab xws li Cowe yog tus thawj coj ntawm qhov kev sib tham no, tsim cov khoom zoo titanium dioxide thaum tseem ceeb ntawm kev tiv thaiv ib puag ncig thiab kev ncaj ncees ntawm cov khoom. Raws li peb taw qhia qhov kev hloov pauv no, cov neeg siv khoom yuav tsum nyob twj ywm thiab txiav txim siab ua raws li lawv cov txiaj ntsig thiab kev txhawj xeeb txog kev noj qab haus huv.
