Titanium dioxide, tseem hu ua titanium dioxide, yog cov xim dawb uas siv dav hauv cov tshuaj pleev ib ce, tshuaj pleev thaiv hnub thiab lwm yam khoom. Nws txoj kev nyab xeeb yeej ib txwm ua kom pom tseeb ntawm cov neeg siv khoom thiab kev lag luam.
1. Khoom thiab kev siv ntawm titanium dioxide
Titanium dioxide yog ib tug dawb inorganic compound lug siv raws li ib tug pigment thiab additive nyob rau hauv cov tshuaj pleev ib ce vim nws zoo heev nkaum hwj chim thiab stability. Nws zoo thaiv UV hluav taws xob thiab yog li tseem ceeb tshwj xeeb hauv cov khoom siv tshuaj pleev thaiv hnub.
2. Kev soj ntsuam kev ruaj ntseg
ib. Qhov cuam tshuam ntawm qhov ntev - raug
Cov kev tshawb fawb cuam tshuam tau pom tias qhov ntev - raug rau cov tshuaj titanium dioxide tsawg tsis muaj kev cuam tshuam loj rau tib neeg kev noj qab haus huv. Qhov no qhia tau hais tias titanium dioxide muaj kev nyab xeeb nyob rau hauv ib txwm siv.
b. Kev nyab xeeb ntawm nano-titanium dioxide
Nyob rau hauv xyoo tas los no, nanoscale titanium dioxide tau siv dav hauv cov tshuaj pleev ib ce vim nws zoo dua dispersion thiab pob tshab. Txawm hais tias muaj kev sib cav txog nws txoj kev nyab xeeb, cov kws tshaj lij ntawm European Commission tau lees paub qhov kev nyab xeeb ntawm nanotitanium dioxide thaum lub Kaum Ib Hlis 2017, ceeb toom tias kev nkag mus ntawm daim tawv nqaij yog tsawg.
c. kev tsis haum tshuaj
Txawm hais tias titanium dioxide nws tus kheej yog suav tias yog inert thiab tsis hnov mob nrog lwm cov khoom xyaw, qee zaus nws tseem yuav ua rau muaj kev tsis haum tshuaj rau cov neeg siv khoom. Qhov no tej zaum yuav yog vim ib tug neeg sib txawv los yog kev sib cuam tshuam nrog lwm yam additives.
3. Kev cai thiab cov qauv
Raws li ib tug zoo- tsim cov khoom ntuj tsim, titanium dioxide tau dhau kev soj ntsuam kev nyab xeeb los ntawm ntau lub koom haum tswj hwm thiab tau pom zoo siv rau ntau yam kev siv. Nws siv hauv cov tshuaj pleev ib ce yog ua raws li cov qauv nruj thiab cov kev cai kom ntseeg tau tias nws muaj kev nyab xeeb.
nyob rau hauv xaus
Hauv cov ntsiab lus, titanium dioxide muaj kev nyab xeeb siv hauv tshuaj pleev ib ce. Txawm hais tias muaj qee qhov kev sib tham txog nws cov kev pheej hmoo, cov kev tshawb fawb tshawb fawb tam sim no thiab kev ntsuam xyuas lub koom haum tswj hwm txhawb nws txoj kev nyab xeeb. Txawm li cas los xij, rau cov neeg siv khoom nrog cov tawv nqaij rhiab, xaiv cov khoom uas tsis muaj lossis tsawg dua titanium dioxide tseem yog qhov kev xaiv zoo.
