Lub luag haujlwm ntawm Organic Txheej ntawm Titanium Dioxide
Lub luag haujlwm tseem ceeb ntawm cov txheej txheem organic yog txhawm rau txhim kho cov ntub dej, dispersion thiab rheological zog ntawm titanium dioxide nyob rau hauv ntau yam xov xwm, kom txo tau qhov nqus dej thaum lub sij hawm cia thiab txo cov adhesion ntawm cov xim. Lub tshuab yog hloov cov khoom nto ntawm titanium dioxide hais.
Muaj ob txoj hauv kev los txuas cov tshuaj kho cov organic rau saum npoo ntawm titanium dioxide hais: ib qho yog lub cev adsorption, vim tias cov txheej txheem organic feem ntau yog surfactant, cov molecule feem ntau yog tsim los ntawm pawg hydrophilic polar thiab ib qho oleophilic uas tsis yog- pawg polar, thaum nws los rau hauv kev sib cuag nrog cov organic titanium dioxide hais, nws cov polar pawg yuav adsorbed rau saum npoo ntawm cov titanium dioxide hais, kom cov non-polar pab pawg neeg raug tsim ib tug organic zaj duab xis nrog affinity ntawm cov xim. puag, yog li ua rau lub interface Lub nro ntawm lub interface yog txo, thiaj li hais tias titanium dawb hais nyob rau hauv cov organic nruab nrab yog dawb, cov pigment hais yog sib cais los ntawm ib tug mus cuag cov nyhuv ntawm dispersion; Lwm txoj kev yog tshuaj adsorption, uas yog, nws reacts nrog hydroxyl pawg nyob rau saum npoo ntawm titanium dawb thiab koom nrog nws.
