Dab tsi ua rau siab alumina refractory cib rov qab mus rau alkali thiab ua kom khov? Kev tiv thaiv thiab kev daws teeb meem yog dab tsi?
High alumina refractory cib yog tsim los ntawm alumina thiab silica, thiab ob qho tib si yuav cuam tshuam rau kev ua haujlwm ntawm cov cib sib txawv. Yog tias cov ntsiab lus alumina siab dhau lawm, cov iav theem cov ntsiab lus hauv cib yuav nce, thiab cov muaju yuav yooj yim los nag hauv qhov kub thiab txias, ua rau hoarfrost. Tsis tas li ntawd, cov ntsiab lus impurity ntau dhau hauv lub cev cib kuj tseem cuam tshuam rau nws qhov kev ua tau zoo.
Dab tsi ua rau siab alumina refractory cib rov qab mus rau alkali thiab ua kom khov?
1. Humidity thiab kub
Thaum lub sij hawm siv high-alumina refractory bricks, yog hais tias lub ambient humidity thiab kub siab heev, ntau noo noo yuav absorbed rau saum npoo. Qhov zoo ntawm noo noo adsorption yuav ua rau lub cev cib ua rau cov tshuaj tiv thaiv corrosion, uas yuav ua rau muaj qhov tshwm sim ntawm alkaline rov qab thiab dawb te.
2. Huab cua cuam tshuam
Yog tias muaj qhov txo qis hauv ib puag ncig qhov twgsiab alumina refractory cibnyob, xws li hydrogen, carbon monoxide, thiab lwm yam., cov pa roj no yuav hnov mob nrog cov khoom hauv lub cib ntawm qhov kub thiab txias. Qhov kev txo qis no ua rau muaj qhov tso nyiaj dawb rau ntawm lub cib saum npoo.
3. teeb meem kev teeb tsa
Yog hais tias cov high-alumina refractory bricks muaj qhov khoob los yog tsis tau ntsia nruj nreem thaum lub installation, qhov no yuav ua rau lawv raug ntxuav los ntawm high-temperature gases thaum siv tom ntej, ua rau lawv raug corrosion.
4. Kev ua haujlwm tsis raug
Thaum siv, yog tias kev ua haujlwm tsis raug lossis kev saib xyuas cov cuab yeej tsis raug raws sijhawm, xws li huab cua to, cov khoom xau thiab lwm yam teeb meem, cov teeb meem no yuav ua rau lub siab alumina refractory bricks yuav tshuaj corroded, yog li tsim hoarfrost.
Yuav ua li cas ntsuas tau los tiv thaiv siab alumina cib rov qab mus rau alkali thiab ua rau dawb te?
1. Xaiv qhov tsim nyog high-alumina refractory cib
Thaum muas high-alumina refractory bricks, koj yuav tsum xaiv cov khoom uas ruaj khov thiab tsim nyog cov khoom xyaw kom tsis txhob muaj teeb meem ntawm alkali rov qab thiab dawb te thaum siv. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los xaiv qhov tsim nyog high-alumina refractory cib raws li qhov siv tau tiag tiag los xyuas kom meej tias lawv cov khoom sib xyaw ua ke raws li kev siv tiag tiag xav tau los muab kev ua si tag nrho rau lawv cov hluav taws-resistant kev ua tau zoo thiab ruaj khov.
2. Tswj kev siv ib puag ncig
Thaum siv high-alumina refractory bricks, ambient humidity thiab kub yuav tsum tau tswj kom tsis txhob muaj kev phiv los ntawm ntau dhau los yog tsawg ib puag ncig. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los xyuas kom meej tias tsis muaj qhov txo qis hauv qhov chaw siv los txo qhov kev pheej hmoo ntawm corrosion ntawm cov cib. Los ntawm kev siv cov kev ntsuas no, kev pab cuam lub neej ntawm high-alumina refractory bricks tuaj yeem txuas ntxiv thiab lawv cov kev ruaj ntseg thiab hluav taws kub-resistant kev ua tau zoo.
3. Txuj kev teeb tsa thiab siv cov haujlwm
Thaum txhim kho siab alumina refractory cib, xyuas kom nruj installation thiab tsis muaj qhov khoob kom tsis txhob muaj cua sov tsis sib xws thiab teeb meem corrosion ntawm cov cib los ntawm huab cua ntws. Nyob rau tib lub sijhawm, thaum siv, kev ua haujlwm thiab kev saib xyuas tus cwj pwm yuav tsum tau ua tus qauv kom tsis txhob muaj teeb meem ntawm alkaline rov qab thiab dawb te los ntawm kev ua haujlwm tsis raug lossis kev saib xyuas cov khoom siv tsis raug. Los ntawm kev txhim kho thiab siv kom raug, kev pab cuam lub neej ntawm high-alumina refractory bricks tuaj yeem txuas ntxiv thiab lawv cov hluav taws-resistant kev ua tau zoo thiab ruaj khov tuaj yeem ua kom ntseeg tau.
4. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua
Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm high-alumina refractory bricks yog cov kev ntsuas tseem ceeb los tiv thaiv lawv rov qab mus rau alkali thiab whitening. Los ntawm kev tshuaj xyuas tsis tu ncua, cov teeb meem ntawm cov cib tuaj yeem tshawb pom nyob rau lub sijhawm thiab cov kev ntsuas sib raug tuaj yeem raug coj los daws lawv, yog li zam kom tsis txhob muaj qhov tshwm sim loj dua los ntawm cov teeb meem hnyav dua. Nyob rau tib lub sijhawm, corroded cib yuav tsum tau ntxuav thiab hloov tsis tu ncua kom ntseeg tau tias kev ua haujlwm ib txwm muaj thiab kev ua haujlwm ntawm cov khoom siv. Los ntawm cov kev ntsuas no, kev pab cuam lub neej ntawm high-alumina refractory bricks tuaj yeem txuas ntxiv thiab lawv cov kev ruaj ntseg thiab hluav taws kub-resistant kev ua tau zoo tuaj yeem ua kom ntseeg tau.
