Daim Ntawv Thov Ntawm Silica Hmoov

Nyob rau hauv daim ntawv thov txheej txheem, silica hmoov yog tsuas yog siv raws li ib tug functional muab tub lim, uas yog compounded nrog organic polymers los txhim kho tag nrho cov kev ua tau zoo ntawm composite cov ntaub ntawv. Microsilica hmoov nws tus kheej yog cov khoom siv polar hydrophilic, nrog cov khoom sib txawv ntawm cov polymer matrix, thiab tsis zoo sib xws. Nws yog feem ntau nyuaj rau disperse nyob rau hauv lub substrate. Yog li ntawd, feem ntau nws yog ib qho tsim nyog los hloov kho qhov saum npoo ntawm silica hmoov thiab txhob txwm hloov lub cev thiab tshuaj lom neeg ntawm silica hmoov nto raws li daim ntawv thov xav tau, txhawm rau txhim kho nws cov kev sib raug zoo nrog cov ntaub ntawv organic polymer, thiab ua tau raws li qhov yuav tsum tau muaj ntawm dispersion thiab flowability nyob rau hauv cov ntaub ntawv polymer. Qhov zoo ntawm silica hmoov raw cov ntaub ntawv, kev hloov kho, txheej txheem kev hloov kho saum npoo thiab kev hloov kho, kev hloov pauv ntau npaum, kev hloov kho cov txheej txheem (kev hloov kho kub, lub sij hawm, pH nqi thiab nplawm nrawm), thiab lwm yam yuav cuam tshuam qhov kev hloov pauv ntawm silica hmoov, thaum Txoj kev hloov kho saum npoo av thiab hom kev hloov kho yog cov yam tseem ceeb uas cuam tshuam rau kev hloov pauv.
