Ua ntawm Silicon Dioxide los ntawm Txoj Kev Ua Los nag

Lub tshuab ntawm kev npaj silica los ntawm txoj kev sedimentation muaj ntau hom:

Ua ntej, siab dispersibilitysilicon dioxideyog npaj nyob rau hauv organic solvent. Qhov thib ob, cov kua qaub ntawm cov kua qaub thiab cov kua silicate aqueous yog siv kom tau txais silicon dioxide tom qab sib cais thiab ziab. Thib peb, alkali hlau silicate thiab inorganic acid yog tov los ua silicon dioxide dej sol, ces nws hloov mus rau hauv cov gel hais, qhuav, kub ntxuav, thiab ces qhuav thiab ci kom tau silicon dioxide. Plaub, carbonization ntawm iav dej yog siv los npaj silicon dioxide. Fifthly, tus du-ntug non-spherical silicon dioxide yog npaj los ntawm tshuaj tsuag granulation.

Cov txheej txheem ntau yam no tau raug pov thawj tias ua tau zoo thiab muaj txiaj ntsig hauv kev npaj silicon dioxide nrog cov yam ntxwv sib txawv thiab cov khoom. Txoj kev sedimentation yog ib qho tseem ceeb thiab siv tau dav hauv cov khoom siv science thiab engineering. Nws cov txiaj ntsig muaj xws li cov txiaj ntsig siab, tus nqi qis, thiab kev ua haujlwm yooj yim. Txoj kev sedimentation tau siv rau hauv ntau daim ntawv thov kev lag luam, xws li tshuaj, khoom siv hluav taws xob, thiab catalysis. Kev txhim kho thiab txhim kho cov txheej txheem sedimentation yuav txhawb kev siv cov silicon dioxide hauv ntau qhov chaw.

Hauv kev xaus, txoj kev sedimentation yog ib qho tseem ceeb hauv kev npaj silicon dioxide. Ntau txoj hauv kev tau tsim los ua kom tau raws li cov kev xav tau sib txawv. Txoj kev sedimentation yog ib qho kev cog lus rau kev npaj ntawm silicon dioxide thiab nws yuav pab txhawb rau kev txhim kho ntawm ntau daim ntawv thov kev lag luam. Peb yuav tsum tau kawm txuas ntxiv thiab txhim kho cov txheej txheem sedimentation los txhawb kev txhim kho ntawm silicon dioxide thiab lwm yam kev lag luam.
