Cov khoom siv tseem ceeb ntawm cov khoom siv alumina desiccant yog qib kev lag luam aluminium hydroxide hmoov, uas yog ib hom oxide yooj yim nrog 3-5% cov dej ntsiab lus, thiab qhov txo qis ntawm alumina hydroxide ntawm 900-1100 ℃ yog 34.5%.
Cov txheej txheem ntau lawm ntawm cov alumina desiccant yog raws li nram no:
Aluminium hydroxide - ziab - zeb mus rau 600 mesh, aluminium hydroxide 300 ℃ qhuav sai - disc molding - 12 teev kev kho mob ua kom muaj zog - los ntawm lub qhov cub shaft 550 ℃ sintering.
1. Hmoov txhuas hydroxide kev lag luam, uas muaj 3-5% dej noo, raug ziab ntawm 120 ℃ los ntawm cov khoom siv ziab loj.
2. Tom qab ziab, hmoov txhuas hydroxide nkag mus rau hauv kev sib tsoo loj thiab tsoo rau 600 meshes. Qhov zoo dua qhov zoo, qhov zoo dua nws yog los ua kom zoo li lub pob ua kom lub pob ua haujlwm. Cov khoom me me uas tsim tawm tsis muaj hmoov thiab muaj zog heev.
3, hmoov txhuas hydroxide, mus rau hauv lub kaw lus degasification ceev rau thawj zaug sintering, txhuas hydroxide hmoov zoo nyob rau hauv lub cua kub turbulent heev nyob 0.10s, lub hauv paus ntsiab lus ntawm kev tsim khoom yog: txhuas hydroxide los ntawm kev ncua roasting sai dehydration, thiab txias sai.
4, siv lub hauv paus ntsiab lus ntawm snowball, kev tsim cov pob alumina ua haujlwm, cov txheej txheem no tuaj yeem ua los ntawm ntau txoj kab uas hla ntawm cov desiccant ua haujlwm alumina thiab cov cab kuj.
5, lub pob ntawm cov khoom siv alumina activated static rau 12 teev, nws tus kheej cua sov thiab dej kom qhib.
6. Thaum kawg, alumina ua haujlwm tau sintered hauv lub qhov cub ntsug, thiab qhov kub thiab txias yog 550-700 ℃.
