Hauv kev tsim khoom lag luam, kev siv tshuab pneumatic conveying yog siv dav hauv kev siv hluav taws xob, tshuaj lom neeg thiab lwm yam lag luam, tab sis kev hnav cov kav dej ib txwm yog teeb meem hauv kev lag luam, ua rau cov nqi nce ntxiv thiab cuam tshuam rau kev tsim khoom. Kev tshwm sim ntawm cov raj alumina uas tsis hnav tau daws qhov teeb meem no thiab dhau los ua qhov kev xaiv tshiab rau kev lag luam.
Cov kav dej alumina uas tiv taus hnav tau muab tso rau hauv cov khoom siv alumina ceramics uas muaj cov khoom huv si, nrog rau qhov nyuaj ze li ntawm 90HRA, thiab qhov tsis kam hnav yog ntau txog ntau npaug ntawm cov kav hlau ib txwm muaj. Thaum cov cua ceev ceev tsav cov ntaub ntawv kom txhuam rau ntawm phab ntsa sab hauv ntawm cov kav dej, nws tuaj yeem tiv taus kev hnav thiab ua kom lub neej ua haujlwm ntev dua. Piv txwv li, hauv lub tuam txhab tshuaj lom neeg, cov kav hlau ib txwm muaj kev hnav hnyav hauv ob peb lub hlis thaum xa cov ntaub ntawv uas muaj cov khoom khov, thiab yuav tsum tau hloov pauv ntau zaus; tom qab hloov nrog cov kav dej alumina uas tiv taus hnav, qhov hnav tsawg kawg nkaus tom qab ntau xyoo ntawm kev ua haujlwm.
Nws kuj muaj kev tiv taus kub zoo. Lub hauv pem teb ceramic tuaj yeem tiv taus kub siab tshaj 1200℃, thiab qhov kub thiab txias kam rau siab dua nyob rau hauv cov txheej txheem tshwj xeeb. Nws tuaj yeem ua haujlwm ruaj khov hauv kev thauj khoom kub siab kom ntseeg tau tias muaj kev nyab xeeb ntawm lub tshuab xa khoom pneumatic. Ntxiv mus, nws muaj kev ruaj khov tshuaj lom neeg muaj zog. Thaum thauj cov khoom siv corrosive hauv kev lag luam tshuaj lom neeg, nws tuaj yeem tiv taus qhov xeb ntawm cov xov xwm xws li acids, alkalis, thiab ntsev kom ntseeg tau tias kev thauj mus los ntawm cov khoom siv tshuaj lom neeg.
Tsis tas li ntawd xwb, lub raj alumina uas tsis yooj yim hnav yog lub teeb yuag, tuaj yeem txo qhov hnyav ntawm cov kav dej, yooj yim rau kev teeb tsa thiab tswj, thiab txo kev siv hluav taws xob. Muaj ntau txoj kev teeb tsa, thiab txoj kev txuas tuaj yeem xaiv raws li qhov xav tau los hloov kho rau cov chaw ua haujlwm nyuaj.
Nrog kev nce qib ntawm thev naus laus zis hauv kev lag luam, qhov yuav tsum tau ua ntau dua rau cov tshuab xa khoom siv pneumatic. Nrog nws cov kev ua tau zoo heev, lub raj alumina uas tsis yooj yim hnav muaj kev cia siab dav dav. Nws tuaj yeem daws cov teeb meem hnav, txhim kho kev ua haujlwm ntau lawm, txo cov nqi, txhawb kev txhim kho thev naus laus zis xa khoom siv pneumatic, thiab pab ntau yam kev lag luam txhim kho nrog qhov zoo. Nws yuav ua lub luag haujlwm tseem ceeb hauv ntau qhov xwm txheej yav tom ntej.
