Kev Hloov Pauv Tshiab Hauv Cov Qauv Kev Lag Luam Txawv Tebchaws ntawm Titanium Dioxide: Kev Sawv Ntxov ntawm Cov Lag Luam Tshiab thiab Kev Sib Koom Ua Ke ntawm Cov Lag Luam Ib Txwm

Tsis ntev los no, titanium dioxide tau qhia txog cov qauv tshiab ntawm kev lag luam thoob ntiaj teb. Hauv cov lag luam tshiab, cov teb chaws xws li Is Nrias teb thiab Brazil tau pom kev lag luam sai sai, thiab qhov kev thov rau titanium dioxide tau nce siab heev. Kev tsim kho thiab kev lag luam tsheb hauv Is Nrias teb tab tom txhim kho sai, tsav tsheb kev vam meej ntawm kev lag luam coatings, yog li ua rau cov khoom xa tuaj ntawm titanium dioxide nce 30% hauv rau lub hlis dhau los. Ntau tus neeg muab khoom thoob ntiaj teb titanium dioxide tau tig lawv lub siab mus rau kev lag luam Is Nrias teb thiab ua tau raws li kev xav tau ntawm kev lag luam los ntawm kev koom tes nrog cov neeg faib khoom hauv zos lossis tsim cov chaw tsim khoom. Hauv cov lag luam European thiab Asmeskas ib txwm muaj, txawm hais tias twb muaj kev lag luam titanium dioxide paub tab lawm, vim muaj cov nqi tsim khoom hauv zos siab thiab kev hloov kho peev xwm ntawm qee lub tuam txhab, ntau titanium dioxide tseem yuav tsum tau xa los ntawm kev lag luam thoob ntiaj teb. Qee lub tuam txhab tsim khoom yas loj hauv Tebchaws Europe tau tsim kev sib raug zoo ntev thiab ruaj khov nrog cov neeg tsim khoom titanium dioxide hauv Asia kom txo cov nqi thiab tau txais cov khoom zoo dua. Piv txwv li, tom qab lub tuam txhab tsim khoom titanium dioxide hauv Suav teb tau dhau daim ntawv pov thawj zoo ntawm European Union, nws tau nkag mus rau hauv cov saw hlau ntawm ntau lub tuam txhab yas paub zoo hauv Tebchaws Europe, thiab nws cov khoom xa tawm tau nce ntxiv txhua xyoo. Ntxiv mus, nrog kev txhim kho ntawm kev paub txog ib puag ncig thoob ntiaj teb, titanium dioxide ntsuab thiab tus phooj ywg ib puag ncig muaj kev sib tw ntau dua hauv kev lag luam txawv teb chaws. Cov khoom titanium dioxide nrog kev siv hluav taws xob tsawg thiab kev ua qias tuaj tsawg uas tsim los ntawm qee cov txheej txheem tshiab tsis txaus hauv kev lag luam thoob ntiaj teb. Qhov no tsis yog tsuas yog ua rau cov tuam txhab tsim khoom nce kev nqis peev hauv kev tshawb fawb thiab kev txhim kho thev naus laus zis tiv thaiv ib puag ncig, tab sis kuj txhawb nqa tag nrho kev lag luam txawv teb chaws titanium dioxide kom txhim kho hauv kev coj ua ntsuab thiab ruaj khov.
