Hauv cov lag luam uas muaj kev cov nyom tas li, kev xaiv cov khoom siv refractory tuaj yeem ua rau lossis rhuav tshem kev ua haujlwm zoo, kev nyab xeeb, thiab kev siv nyiaj tsim nyog. Cov tshuaj mortar refractory alumina siab Nws yog ib yam khoom siv tseem ceeb uas siv tau rau ntau yam kev siv, xws li kev ua kom kub thiab txias, kev puas tsuaj ntawm cov tshuaj lom neeg, thiab kev puas tsuaj ntawm cov khoom siv kho tshuab. Txawm koj nyob hauv kev lag luam hlau, kev tsim cov khoom siv av nplaum, kev tsim iav, lossis lwm yam kev lag luam uas xav tau kev sib txuas uas tiv taus cua sov, cov khoom siv tshwj xeeb no muaj kev ua tau zoo uas lwm cov khoom siv dav dav tsis tuaj yeem sib piv tau. Cia peb kawm seb vim li cas cov khoom siv refractory alumina siab yog qhov kev xaiv zoo tshaj plaws rau kev siv kub thiab txias thoob ntiaj teb.
Ua ntej tshaj plaws, cov tshuaj mortar refractory alumina siab zoo tshaj plaws hauv kev siv hlau, ib qho chaw uas qhov kub feem ntau nce siab tshaj 1500 ° C. Hauv cov chaw ua hlau, nws siv dav rau kev sib txuas cov cib refractory hauv cov cub tawg, cov tais diav, cov tundishes, thiab cov cub hluav taws xob arc. Cov ntsiab lus alumina siab (feem ntau 70% txog 90%) ua rau nws muaj kev tiv thaiv zoo heev, tiv thaiv kev yaj lossis kev hloov pauv txawm tias nyob hauv qhov kub ntawm cov hlau yaj. Tsis tas li ntawd, nws tiv taus kev xeb los ntawm cov slag yaj, cov hlau oxides, thiab lwm yam tshuaj lom neeg uas feem ntau pom hauv kev tsim hlau. Qhov kev ruaj khov no txo lub sijhawm tsis ua haujlwm los ntawm kev ua haujlwm tsis zoo, ua kom ntseeg tau tias kev ua haujlwm txuas ntxiv thiab txo cov nqi kho rau cov chaw tsim hlau.
Cov lag luam ceramics thiab iav kuj vam khom ntau rau cov tshuaj mortar refractory alumina siab. Cov cub tawg ceramic, siv rau kev hlawv cov tais diav av nplaum, vuas, thiab cov khoom siv ceramics siab heev, ua haujlwm ntawm qhov kub ntawm 1200 ° C thiab 1800 ° C. Cov tshuaj mortar alumina siab muab kev sib txuas ruaj khov, ruaj khov rau cov ntaub refractory hauv cov cub tawg no, tswj kev ruaj khov txawm tias thaum lub sijhawm ua kom sov thiab txias dua. Rau cov cub tawg iav, qhov twg qhov kub tshaj 1600 ° C, qhov kev tiv thaiv ntawm cov tshuaj mortar rau kev poob siab thermal yog qhov tseem ceeb. Nws tiv thaiv cov kab nrib pleb thiab spalling los ntawm kev hloov pauv kub sai, txuas ntxiv lub neej ntawm cov ntaub hauv cub tawg thiab ua kom cov iav zoo sib xws. Tsis zoo li cov tshuaj mortars qis-alumina, nws tsis cuam tshuam nrog cov iav yaj, zam kev ua qias tuaj uas tuaj yeem ua rau cov khoom iav puas tsuaj.
Lwm daim ntawv thov tseem ceeb yog nyob rau hauv petrochemical thiab thermal fais fab nroj tsuag. Hauv boilers, incinerators, thiab reformers, siab alumina refractory mortar bonds refractory Cheebtsam uas ntsib kub siab, flue gases, thiab tshuaj lom neeg tawm tsam los ntawm roj thiab by-products. Hauv cov nroj tsuag hluav taws xob thee, nws tiv taus qhov xwm txheej abrasive ntawm cov tshauv ya thiab cov teebmeem corrosive ntawm sulfur oxides. Hauv petrochemical crackers thiab reformers, nws tiv taus degradation los ntawm hydrocarbons thiab kub kub, ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Nws cov khoom zoo heev adhesion kuj ua rau nws zoo tagnrho rau kev kho cov refractory linings puas tsuaj, txo qis downtime thiab ntev lub neej kev pabcuam ntawm cov khoom siv tseem ceeb.
Ntxiv rau cov kev lag luam tseem ceeb no, cov tshuaj mortar alumina siab pom siv rau hauv cov chaw hlawv pov tseg, qhov chaw nws tswj cov kub siab thiab cov pa roj corrosive uas tsim los ntawm kev hlawv cov khib nyiab hauv nroog thiab kev lag luam. Nws tseem ceeb heev rau hauv cov chaw tsim khoom rau cov pwm thiab cov crucibles siv rau hauv cov hlau casting. Nws qhov kev hloov pauv tau yooj yim, ua ke nrog nws qhov kev tiv taus cua sov thiab kev ruaj khov zoo, ua rau nws yog qhov kev daws teeb meem thoob ntiaj teb rau txhua daim ntawv thov uas xav tau kev sib txuas zoo hauv cov chaw kub heev.
Thaum xaiv cov mortar refractory uas muaj alumina siab, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom zoo uas ua tau raws li cov qauv kev lag luam. Nrhiav cov mortar uas muaj qhov sib npaug ntawm cov khoom me me, muaj zog lo rau, thiab tiv taus kev co thermal zoo heev. Peb cov mortar refractory uas muaj alumina siab yog tsim los ntawm kev siv cov khoom siv raw zoo tshaj plaws thiab cov txheej txheem ua tiav siab heev, kom ntseeg tau tias nws muaj kev ua tau zoo tshwj xeeb hauv cov ntawv thov uas xav tau ntau tshaj plaws. Txawm hais tias koj xav tau kab hlau loj rau lub cub tawg hlau, kho lub cub tawg ceramic, lossis tswj lub boiler fais fab, peb cov mortar muab kev ntseeg siab thiab lub neej ntev uas koj xav tau kom koj cov haujlwm ua haujlwm tau zoo.
Tsis txhob txo qhov kev ua tau zoo thaum nws los txog rau kev siv kub siab. Xaiv cov tshuaj mortar refractory alumina siab rau kev tiv taus cua sov zoo dua, tiv taus corrosion, thiab ruaj khov. Tiv tauj peb hnub no kom paub ntau ntxiv txog peb cov khoom thiab lawv tuaj yeem txhim kho koj txoj kev ua haujlwm zoo li cas thiab txo cov nqi kho.
