Hauv kev tsim cov cement, cov khoom siv xws li cov kav dej xa khoom, cov tsev sib cais, cov cua daj cua dub, thiab cov chutes raug kev cuam tshuam ntev thiab kev hnav khaub ncaws, ua rau cov hlau poob sai thiab cov nqi kho kom tsis txhob poob. Kev siv cov alumina ceramic sab hauv uas tsis hnav khaub ncaws ua rau lub neej ua haujlwm ntev dua. Cov sab hauv no yog tsim los ntawm kev sintering kub siab, nrog cov ntsiab lus alumina tsis tsawg dua 92%, qhov ceev ntawm cov khoom loj ≥3.60 g / cm³, Rockwell hardness (HRA) siab dua 85, thiab qhov ntim hnav qis dua 0.1 cm³ (sim raws li GB / T 8489-2006).
Piv rau cov phaj hlau uas tiv taus hnav ib txwm muaj (piv txwv li, NM400), cov txheej txheem alumina ceramic qhia txog kev tiv taus hnav ntau dua li 5–8 npaug, nrog rau qhov sib txhuam ntawm qhov chaw qis (kwv yees li 0.2–0.3 nyob rau hauv qhov chaw qhuav), txo cov khoom siv lo rau thiab kev pheej hmoo ntawm kev thaiv. Cov vuas ceramic raug kho rau phab ntsa sab hauv ntawm cov khoom siv siv epoxy resin lossis cov nplaum inorganic, nrog rau qhov kub ua haujlwm ntawm -50 ° C txog 300 ° C thiab kev kam rau lub sijhawm luv luv txog li 500 ° C. Nyob rau hauv cov xwm txheej ib txwm muaj ntawm cov nroj tsuag cement, cov txheej txheem ceramic txuas ntxiv lub neej ua haujlwm ntawm chute los ntawm 6 lub hlis mus rau ntau dua 36 lub hlis.
Cov ntaub thaiv no tau siv rau cov khoom tseem ceeb xws li cov chutes pub zeb, cov vanes qhia kev sib cais, cov cyclone cones, thiab cov kav dej clinker hauv cov chaw tsim cement. Cov ntaub ntawv hauv daim teb qhia tau tias nyob rau hauv qhov nruab nrab ntawm cov khoom siv me me ntawm 30 hli thiab linear velocity ntawm 15 m / s, tom qab 12 lub hlis ntawm kev ua haujlwm tas mus li, qhov tob hnav ntawm cov vuas ceramic tsuas yog 0.2–0.5 hli, thiab cov khoom siv kho tau ntev mus txog plaub npaug ntawm lub sijhawm qub. Muaj nyob rau hauv cov phaj ceramic modular lossis mosaic tile patches, cov ntaub thaiv hloov kho rau cov khoom siv nrog ntau yam curves thiab cov duab qauv.
Kev txhawb nqaCov khoom siv alumina ceramic uas tsis yooj yim hnav hauv cov khoom siv cement engineeringua kom txo tau kev siv cov khoom seem thiab kev poob sijhawm tsis ua haujlwm, txhim kho tag nrho cov nqi ua haujlwm ntawm cov kab ntau lawm. Thaum lub sijhawm teeb tsa, xyuas kom meej tias qhov chaw ntawm cov khoom siv huv si thiab tsis muaj roj; lub sijhawm kho cov nplaum yuav tsum tsis pub tsawg dua 24 teev (ntawm 25 ° C). Rau cov kaum sab xis cuam tshuam ntau dua 45 ° ntawm cov ntsiab lus poob ntawm cov khoom siv, cov txheej txheem buffer raug pom zoo kom ua kom zoo dua qhov kev tiv thaiv kev cuam tshuam. Cov thev naus laus zis no tau koom ua ke rau hauv ntau tus qauv tsim kev tiv thaiv kev hnav hauv kev lag luam cement.
