Cov cuab yeej deg ntawm titanium dioxide
Raws li cov chaw tsim tshuaj txog chaw tsim tshuaj paus titanium dioxide, kho cov khoom saum npoo ntawm titanium dioxide raws li cov khoom lag luam sib txawv thiab cov neeg siv xav tau yog txoj hauv kev siv tau yooj yim thiab yooj yim. Qhov kev hloov kho no tuaj yeem ua tiav los ntawm txheej txheej inorganic, kev kho mob organic, lossis kev sib koom ua ke ntawm ob.
Kev kho cov organic yog tam sim no siv los ntawm ntau thiab ntau cov tuam ntxhab hauv kev tsim cov khoom siv titanium dioxide kev lag luam. Lub ntsiab cai tseem ceeb yog tias cov tshuaj tua kab mob me me tuaj yeem muab tua nyob rau saum npoo ntawm titanium dioxide los ntawm kev ua ntawm tus choj hydroxyl, thiab tom qab ntawd rub tawm mus rau hauv cov kab ke. Ntau pawg hydrophilic los yog pab pawg lipophilic los yog ob qho tib si, yog li txhim kho qhov khoom tawg yooj yim hauv cov kab ke sib txawv.
Hauv cov txheej txheem ntau lawm ntawm titanium dioxide, cov tshuaj tua kab mob organic feem ntau kuj tuaj yeem ua lub luag haujlwm hauv kev pab sib tsoo, thiab tuaj yeem txhim kho lwm yam khoom xws li xim dawb, decolorization tus nqi, thiab cov yam ntxwv ntawm cov khoom lag luam. Yog li no, ntau cov chaw tsim khoom hauv lub tebchaws tau nce siab los ntawm kev siv tshuaj tua kab mob ua ib qho tseem ceeb rau kev kho cov khoom saum npoo ntawm titanium dioxide.
Txawm li cas los xij, cov lus qhia ntawm cov tshuaj tua kab mob organic thaum dispersing hauv cov dej theem txheej txheem feem ntau ua rau muaj teeb meem ntawm cov npuas dej ntau dua, uas yuav ua rau cov teeb meem tsis tsim nyog rau tus neeg siv, thiab txawm tias ncaj qha ua rau qee qhov kev ua haujlwm tsis zoo ntawm cov txheej. Yog li, peb tseem tuaj yeem xav txog kev txhim kho cov khoom saum npoo ntawm titanium dioxide los ntawm kev kho mob inorganic kom kov yeej cov lus saum toj no. Raws li tau hais dhau los, cov txheej txheem kev sib txawv hauv cov txheej txheem muaj peev xwm hloov tau cov khoom thaj chaw ntawm titanium dioxide. Yog li, peb tau sim ntau txoj hauv kev kho cov txheej txheem rau cov txheej txheem tha xim sab nrauv phab ntsa latex, thiab thaum kawg txiav txim siab tam sim no NR950 cov txheej txheem ntau lawm, thiab ua tiav qee yam Ua tau Zoo. Vim tias cov khoom lag luam qauv no tau dhau qhov kev tsis txaus ntawm kev ua npuas, nws tau yeej kev qhuas los ntawm cov neeg siv khoom.
Ntawm lub hauv paus ntawm kev kho mob inorganic, kev kho mob organic yog tswj ntawm qib tsim nyog, thiab kev ua haujlwm ntawm peb cov khoom yuav muaj cov txiaj ntsig zoo.
