Cov Yeeb Nkab Hlau Uas Tiv Thaiv Tau Alumina Ceramic Lined: Cov Khoom, Kev Tsim Khoom, thiab Daim Ntawv Thov

Alumina ceramic lined steel yeeb nkabyog ib lub raj xa dej ua los ntawm kev sib txuas ua ke ntawm cov alumina ceramic uas muaj cov khoom siv siab heev rau sab hauv phab ntsa ntawm cov yeeb nkab hlau. Cov txheej ceramic feem ntau muaj tsawg kawg 95% alumina (Al₂O₃), nrog rau Rockwell hardness siab dua HRA85 thiab Mohs hardness kwv yees li qib 9, thib ob tsuas yog pob zeb diamond. Cov qauv no ua ke qhov kev tiv thaiv kev hnav siab ntawm alumina ceramic nrog lub zog thiab kev tawv ntawm cov hlau, ua rau nws haum rau cov xwm txheej abrasive hnyav. Cov qauv tsim yeeb nkab ua raws li cov qauv engineering thiab tso cai rau kev hloov kho qhov ntev, txoj kab uas hla, thiab cov txheej txheem txuas.

Cov txheej txheem tsim khoom tseem ceeb yog txoj kev sib txuas cov nplaum thiab txoj kev vuam. Txoj kev nplaum siv cov nplaum uas muaj zog heev, tiv taus cua sov los kho cov vuas ceramic alumina uas tau ua tiav lawm rau ntawm phab ntsa hlau sab hauv, tsim nyog rau qhov kub nruab nrab mus rau qis (feem ntau ≤150 ° C). Txoj kev vuam siv cov txheej txheem vuam tshwj xeeb los txuas cov vuas ceramic perforated ncaj qha rau ntawm phab ntsa hlau sab hauv, tsim kom muaj kev sib txuas hlau ntawm cov ceramic thiab cov yeeb nkab hauv paus, uas ua rau tiv taus qhov kub siab dua (feem ntau ≤350 ° C) thiab muaj zog dua. Ob qho txheej txheem ua kom ntseeg tau tias cov ceramic liner du, tsis tawg nrog kev sib txuas txhim khu kev qha rau cov yeeb nkab hauv paus.

Qhov zoo ntawm cov kav dej no yog nws txoj kev tiv thaiv kev hnav zoo heev thiab lub neej ntev. Nyob rau hauv cov xwm txheej ua haujlwm zoo sib xws, nws txoj kev tiv thaiv kev hnav yog ntau dua 20 npaug ntawm cov kav hlau carbon ib txwm muaj, txo qhov zaus hloov pauv thiab cov nqi txij nkawm. Tsis tas li ntawd, nws muaj kev tiv thaiv corrosion zoo thiab qhov chaw du sab hauv, uas txo cov khoom siv thiab kev thauj mus los tsis zoo. Nws yog siv dav hauv kev lag luam xws li kev tsim hluav taws xob, metallurgy, mining, thiab kev ua tshuaj rau kev thauj hmoov, kev tuav cov tailings, thiab cov tshuab xa khoom pneumatic, zoo daws cov teeb meem kev hnav ntau dhau ntawm cov kav dej.
