Cov khoom siv refractory yog ib ceg hauv kev lag luam silicate. Nws tau tsim lig thiab keeb kwm ntawm cov cement thiab Castable Refractory Cement Factory. Txawm li cas los xij, nyob rau xyoo tas los no, nws tau tsim kho sai thiab tau tsim rau hauv kev lag luam uas muaj kev ywj pheej loj.
Refractory resistant cement kuj hu ua aluminate cement. Aluminate cement yog ua los ntawm txhuas thiab txhuas av thiab limestone hauv Castable Refractory Cement Factory. Kev tua hluav taws yog siav nrog calcium calcium uas yog cov khoom tseem ceeb thiab cov ntsiab lus ntawm txhuas txhuas ntawm li 50 feem pua. Aluminium -acid cement feem ntau yog daj lossis xim av, thiab nws kuj yog grey. Cov zaub mov tseem ceeb ntawm aluminate cement tau dhau los ua aluminium acid thiab lwm yam txhuas acid, nrog rau ib qho me me ntawm calcium silicate.
1. Refractory resistant cement yog ib qho kev sib khi uas siv rau hauv cov neeg ua haujlwm kub lossis cov ntaub thaiv phab ntsa.
2. Hom cement no txawv ntawm lwm hom cement, thiab nws tseem tuav cov khoom sib xyaw ua ke ntawm qhov kub thiab txias.
3. Hluav taws kub tsis kam cement yuav tsim ib qho kev siv zog ntawm chav tsev kub kom ntseeg tau tias qhov hardening ntawm prefabricated qhov chaw.
4. Tsis tas li ntawd, muaj qee cov chemistry ntawm lub cev uas ua kom khov ntawm chav tsev kub. Xws li sai sai precipitating cov dej sab hauv hauv cov cement seem los ntawm cov txheej txheem cement solidification, los yog cov qauv sab hauv yog nruj nreem ntxiv.
Refractory resistant cement tseem hu ua aluminate cement hauv Castable Refractory Cement Factory. Aluminate cement yog ua los ntawm txhuas thiab txhuas av thiab limestone. Kev tua hluav taws yog siav nrog calcium calcium uas yog cov khoom tseem ceeb thiab cov ntsiab lus ntawm txhuas txhuas ntawm li 50 feem pua. Aluminium -acid cement feem ntau yog daj lossis xim av, thiab nws kuj yog grey. Cov zaub mov tseem ceeb ntawm aluminate cement tau dhau los ua aluminium acid thiab lwm yam txhuas acid, nrog rau ib qho me me ntawm calcium silicate.
Cement nrog cov hluav taws kub tsis tsawg tshaj 1580 degree C. Nws tuaj yeem muab faib ua aluminium-resistant refractory cement, qis-calcium aluminium-resistant refractory cement, calcium magnesium -magnesium -pyrite cement, thiab cov huab cua dawb refractory cement.
Thaum cov hluav taws kub-resistant cement rauv yog ci, raws li Castable Refractory Cement Factor, kuv qhia koj yuav tsum xyuam xim rau cov hauv qab no:
1) Ntawm 350 degrees ntawm chav tsev kub, nws feem ntau yuav ua rau tawg hauv zos. Ua tib zoo saib xyuas kom maj mam ci. Yog tias tseem muaj cov pa ntau ntau tom qab 350 degrees rwb thaiv tsev, qhov cua sov yuav tsum tau qeeb.
2) Nyob rau hauv cov xwm txheej ntawm qhov cua tsis zoo thiab dej thiab roj tsis yooj yim rau kev tso tawm, lub sijhawm rwb thaiv tsev yuav tsum raug ncua kom tsim nyog.
3) Thaum ci nrog cov roj hnyav, tiv thaiv cov roj hnyav los ntawm kev txau rau ntawm qhov cub kom tiv thaiv kev tawg hauv zos.
4) Thaum ci nrog hluav taws, nws feem ntau ua rau cov cua sov hauv zos kom ceev heev rau cov nplaim taws thiab yuav tsum tiv thaiv.
5) Cov hluav taws kub-resistant cement tuaj yeem ci yam tsawg 3 hnub tom qab 3 hnub.
6) Cov cua txias ntawm refractory cement rauv yuav tsum tau qeeb kom tsis txhob muaj cua txias.
