Dab tsi yog Cov Yam Tseem Ceeb Uas Muaj Feem Xyuam Dawb ntawm Titanium Dioxide?
Titanium dioxide ua cov xim zoo nkauj dawb rau cov txheej txheej, nws cov xim dawb yog qhov tseem ceeb, yog ib qho tseem ceeb ntawm cov txheej txheem txheej txheem, titanium dioxide whiteness tsis zoo, yuav cuam tshuam ncaj qha rau cov tsos ntawm txheej zaj duab xis.
(1) Cov impurities
Lub ntsiab tseem ceeb cuam tshuam rau qhov dawb ntawm titanium dioxide yog hom thiab cov ntsiab lus tsis zoo, vim tias titanium dioxide yog rhiab heev rau impurities, tshwj xeeb tshaj yog rutile titanium dioxide, yog li txawm tias ib qho kab ntawm impurities, yuav muaj kev cuam tshuam loj rau cov dawb ntawm titanium dioxide. . Hauv cov txheej txheem titanium dioxide, tshwj xeeb tshaj yog cov txheej txheem sulfuric acid titanium dioxide, feem ntau ntawm kev ua haujlwm yog tshem tawm cov impurities ntawm cov khoom, vim tias cov impurities cuam tshuam rau daim ntawv thov kev ua haujlwm ntawm titanium dioxide, tshwj xeeb tshaj yog cov dawb.
Feem ntau cov xim dawb ntawm titanium dioxide uas ua los ntawm txoj kev chloride feem ntau zoo dua li ntawm titanium dioxide uas ua los ntawm sulfuric acid txoj kev, feem ntau yog vim cov ntaub ntawv raw siv hauv kev tsim cov titanium dioxide los ntawm cov txheej txheem chloride titanium tetrachloride tau distilled thiab purified, Nws tus kheej tsis tshua muaj impurity cov ntsiab lus, thaum lub siab impurity ntsiab lus ntawm raw cov ntaub ntawv siv nyob rau hauv txoj kev sulfuric acid, tsuas yog tshem tawm los ntawm kev ntxuav thiab bleaching thiab lwm yam txheej txheem technologies kom tshem tawm impurities.
(2) Titanium dioxide crystal hom
Rutile crystalline titanium dioxide yog yooj yim dua los nqus lub teeb luv luv dua li anatase, yog tias muaj ntau cov rutile crystals sib xyaw hauv cov anatase titanium dioxide, titanium dioxide nqus coefficient K tus nqi ntawm lub teeb yuav nce, qhov whiteness thiab gloss ntawm cov khoom tiav yuav dhau los ua. pluag.
(3) Particle loj thiab particle loj faib
Qhov loj me thiab qhov loj me me yog qhov tseem ceeb cuam tshuam rau qhov dawb ntawm titanium dioxide, feem ntau yog los ntawm kev xav ntawm titanium dioxide hais txog lub teeb, tawg thiab lwm yam tshwm sim. Raws li cov ntaub ntawv ntsuas muaj, nyob rau hauv ib qho me me qhov ntau, qhov me me ntawm qhov loj me ntawm titanium dioxide, qhov siab dua tus nqi whiteness, uas yog vim qhov me me ntawm qhov loj me ntawm titanium dioxide, qhov nce hauv qhov chaw, lub teeb. reflection, diffuse reflection muaj zog.
(4) Particle puab
Particle puab yog hais txog lub xeev ntawm lub neej ntawm titanium dioxide hais, yuav muab faib ua spherical, pas nrig-puab thiab laminar. Raws li cov ntaub ntawv ntsuas muaj qhia tau hais tias qhov dawb ntawm laminated titanium dioxide yog me ntsis qis, kheej kheej thiab tus pas nrig-zoo li tus whiteness yog ze heev, yog li cov duab ntawm titanium dioxide tuaj yeem cuam tshuam me ntsis rau qhov dawb.
(5) Cov ntsiab lus titanium
Titanium cov ntsiab lus hais txog tag nrho cov ntsiab lus ntawm titanium dioxide nyob rau hauv titanium dioxide hmoov, rau cov xim qib titanium dioxide cov ntsiab lus feem ntau yog siab tshaj 90 feem pua, tshwj xeeb tshaj yog nyob rau hauv 92 feem pua rau 98 feem pua, lwm yam tshuaj yog coatings nrog ib tug me me ntawm impurities. Raws li cov ntaub ntawv ntsuas muaj qhia tau hais tias nrog kev nce hauv titanium dioxide cov ntsiab lus, tus nqi whiteness kuj nce.
(6) Ntau yam additives
Hauv kev tsim khoom, feem ntau siv rau ntau yam khoom siv ntxiv, xws li cov khoom siv lim dej, cov roj nplua nyeem, thiab lwm yam, uas yuav muaj cov roj carbon ntev ntev ntawm cov organic tebchaw, kub kub yuav carbonized, kom cov xim titanium dioxide ua npub, txawm tias pom tseeb liab- xim av.
