Cov Whiteness Titanium Dioxide daim ntawv thov rau hauv hnab yas los soj ntsuam
Nov 17, 2015

Titanium dioxide pigments rau lub colouring ntawm uas, tus txheej txheem uas tam sim no nws kuj yog siv inks, xim tsev thiab lwm cov kev qhia, rau tus uas coloring tsis txaus kom pom tau tias yam khoom ntawm tus ua thiab daim ntawv thov yuav tsum tau, xws li kuj kub, weather kuj, thiab kev koom nrog lub polymer los yog additives. Cooline tuam txhab tshuaj technicians yuav coloring titanium dioxide pigments rau cov uas yuav tsum tau muaj cov lus hais txog kev kawm ntawv Performance index ua. No qhov teeb meem tsom rua cov hmoov dawb dawb titanium daim ntawv thov rau hauv hnab yas whiteness kev tshuaj ntsuam.

Dawb yog ib qhov tseem ceeb tshaj cov yam ntxwv ntawm titanium dioxide. Whiteness yog le xaav siv qhov muag saib thiab cov lus txiav txim lawm reflecting lub "dawb nroog" nyob rau hauv kev tshawb xav, lub ntsiab lus teb tawg electromagnetic, tsuas 380nm rau 780 nm wavelengths tawg taus ua rau neeg xav tias cov no sib hu ua sib pom. Feem ntau peb saib cov khoom sib txawv xim zoo nkauj, yog ua tau nruas rau kev zom zaubmov cov tsis lub teeb uas txawv wavelengths thaum pom lub teeb haum thiab thiaj yuav daim ntawv. Ua txhais, teeb khoom haum pom lub teeb thiab thiaj yuav sib txawv ntawm daim ib qho xim zoo nkauj. Thaum txhua lub teeb nyob hauv qhov pom ntau yam lub teeb tusyees diffuse scattering, lub teeb haum, thaum lub teeb tseem ua li khiav ri, lub cev pib dawb ntshiab, nyob hauv kev tshawb xav, hu ua tus caw dawb.

Vim yog lub titanium dioxide uas muaj xim dawb, lawv siv qhov twg lawv dawb yuav tsum yog tib yam, tsis hais leej twg li ntawd, kom paub tias cov whiteness yog lub tswvyim tus kwv tij, nyob hauv tib siv nyob rau hauv nruab nrab dispersion xim rau disperse tom qab tus qauv thiab txheem qauv rau xim sib piv. Kuaj tau whiteness ntawm cov uas yuav siv tau los thov ib yam zoo coj mus kuaj thiab txheem kuaj hauv qhov tib hybrid ua masterbatches, uas siv tshuab, dua qub dilution and txhaj mus rau hauv lub thawv hom phaj, ces ho kuaj lub nrws xim thiab kuaj ntawm chromatic aberration.
