Hom Rutile
Titanium dioxide yog cov khoom siv tshuaj inorganic raw, uas siv dav hauv kev tsim khoom lag luam xws li cov tshuaj pleev xim, yas, roj hmab, ntawv, luam ntawv, tshuaj fibers, thiab tshuaj pleev ib ce. Titanium dioxide muaj ob hom siv lead ua: rutile thiab anatase. Rutile titanium dioxide, uas yog, R-hom titanium dioxide; anatase titanium dioxide, uas yog, A-hom titanium dioxide.
Rutile titanium dioxide muaj cov yam ntxwv zoo heev xws li ua haujlwm tau zoo thaum kub, ua haujlwm tau zoo thaum kub qis, ua haujlwm tau zoo thaum xeb, muaj zog heev, thiab tsis hnyav heev. Piv nrog rau anatase titanium dioxide, nws ua haujlwm tau zoo dua thaum huab cua hloov pauv thiab ua haujlwm tau zoo dua thaum muaj photooxidative. Rutile hom (R hom) muaj qhov ceev ntawm 4.26g/cm3 thiab qhov ntsuas refractive ntawm 2.72. R-hom titanium dioxide muaj cov yam ntxwv ntawm kev ua haujlwm tau zoo thaum huab cua hloov pauv, ua haujlwm tau zoo thaum dej tsis nkag, thiab tsis yooj yim hloov daj. Rutile titanium dioxide muaj ntau yam zoo hauv ntau yam kev siv. Piv txwv li, vim nws cov qauv, cov xim uas nws tsim tawm muaj xim ruaj khov dua thiab yooj yim dua rau xim. Nws muaj peev xwm ua kom muaj xim zoo thiab tsis ua rau lub ntsej muag sab saud puas. Xim nruab nrab, thiab xim ci, tsis yooj yim ploj mus. -
Anatase
Titanium dioxide yog cov khoom siv tshuaj inorganic raw, uas siv dav hauv kev tsim khoom lag luam xws li cov tshuaj pleev xim, yas, roj hmab, ntawv, luam ntawv, tshuaj fibers, thiab tshuaj pleev ib ce. Titanium dioxide muaj ob hom siv lead ua: rutile thiab anatase. Rutile titanium dioxide, uas yog, R-hom titanium dioxide; anatase titanium dioxide, uas yog, A-hom titanium dioxide.
Titanium-hom titanium dioxide yog ib hom titanium dioxide pigment-grade, uas muaj cov yam ntxwv ntawm lub zog zais, lub zog tinting siab, tiv thaiv kev laus thiab tiv taus huab cua zoo. Anatase titanium dioxide, lub npe tshuaj titanium dioxide, mis molecular Ti02, qhov hnyav molecular 79.88. Hmoov dawb, qhov ceev ntawm qhov sib piv 3.84. Lub zog tsis zoo li rutile titanium dioxide, lub teeb tsis kam, thiab cov nplaum txheej yooj yim rau pulverize tom qab ua ke nrog resin. Yog li ntawd, nws feem ntau siv rau cov khoom siv hauv tsev, uas yog, nws feem ntau yog siv rau cov khoom uas tsis dhau los ntawm tshav ntuj ncaj qha.
