Titanium Dioxide nqi ceev ceev ruaj khov
Lub Plaub Hlis xaus, titanium dioxide tus nqi lag luam tseem ceeb ruaj khov. Txog rau hnub no, nws tsis yog hais txog qhov thib peb ntawm tus nqi nce hauv xyoo ua ntej, vim tias qhov xwm txheej ntawm tus nqi nce ntawm ntau tus neeg tsim khoom sib txawv, lub zog ntawm kev tuav ntawm tus nqi kuj txawv.
Lub khw muag khoom tam sim no nyob rau hauv lub xeev tsis zoo ntawm kev yuav thiab muag, thiab lub xeev ntawm kev xa khoom xa tuaj tsis zoo. Piv nrog rau yav dhau los, cov neeg tsim khoom cov khoom lag luam tau nce me ntsis, cov ntawv xaj qub yog nyob rau hauv tus txheej txheem ntawm kev xa tawm thaum qhov kev txiav txim tshiab tsis tau khaws cia. Qhov tseeb, tus nqi ntawm cov neeg tsim khoom tseem yog qhov tseem ceeb, nyob rau hauv cov ntaub ntawv ntawm kev xa khoom tsis zoo, lawv nyiam tswj kev pib tus nqi, tsis yog hloov cov nqi mus rau qis dua, vim tias txawm tias tus nqi hloov pauv, nws tsis tuaj yeem hloov pauv rov qab. xav tau.
Nyob rau hauv qhov tseeb, tam sim no tus nqi theem tseem yog qhov txawv txav, cov neeg tsim khoom tsis tuaj yeem tau txais txiaj ntsig, thaum cov neeg siv qis qis xav tias tus nqi siab vim tsis muaj kev thov. Txawm hais tias qhov kawg thov tsis muaj zog, tab sis tseem muaj, qhov kev thov no tseem yuav tsum tau siv titanium dioxide, yog li tus neeg muag khoom nrog qhov zoo ntawm cov khoom, tus nqi thiab kev pabcuam tseem tuaj yeem tswj cov khoom xa tuaj tsis tu ncua.
