Dab tsi yog cov tshuaj muaj pes tsawg leeg, proportions thiab batching txoj kev ntawm refractory mortar?
Refractory mortar yog ib yam khoom tshwj xeeb uas ua los ntawm ntau yam khoom siv raw. Nws cov tshuaj muaj pes tsawg leeg, kev faib ua feem thiab cov txheej txheem batch muaj qhov cuam tshuam tseem ceeb rau nws qhov kev ua tau zoo thiab siv cov teebmeem.
Chemical Cheebtsam:
Refractory mortarFeem ntau yog tsim los ntawm oxides xws li alumina, silicon oxide, thiab calcium oxide. Ntawm lawv, alumina yog qhov tseem ceeb, nws cov ntsiab lus feem ntau yog ntau tshaj 30%, thiab nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho refractoriness. Tsis tas li ntawd, silicon oxide kuj yog ib qho ntawm cov khoom tseem ceeb, nws cov ntsiab lus feem ntau yog ntau tshaj 10%, uas tuaj yeem txhim kho lub zog thiab ruaj khov ntawm cov khoom.
Qhov ratio:
Qhov kev faib ua feem ntawm refractory mortars raws li nws cov kev siv thiab kev ua tau zoo. Feem ntau hais lus, qhov siab dua ntawm alumina thiab silica cov ntsiab lus, qhov siab dua qhov refractoriness thiab lub zog. Nyob rau tib lub sijhawm, txhawm rau txhim kho qhov fluidity thiab plasticity ntawm cov khoom, qee cov binders thiab cov kuab tshuaj feem ntau yog ntxiv.
Cov khoom xyaw:
Txoj kev sib tov ntawm refractory mortar feem ntau suav nrog cov kauj ruam hauv qab no:
1. Txheeb xyuas cov ntsiab lus thiab kev faib ua feem ntawm txhua yam khoom siv raw raws li kev siv thiab kev ua haujlwm.
2. Sib tov cov khoom siv raw ua ke raws li qhov kev faib ua feem, ntxiv cov dej tsim nyog thiab do.
3. Thaum lub sij hawm sib tov, cov khoom siv ntxiv xws li cov binders thiab cov kuab tshuaj tuaj yeem maj mam ntxiv los txhim kho cov fluidity thiab plasticity ntawm cov khoom.
4. Tom qab nplawm tusyees, cia nws zaum rau ib pliag kom cov ntaub ntawv nyoos tuaj yeem ua rau tag nrho thiab ua ke.
5. Muab cov khoom sib xyaw refractory mortar rau hauv lub hnab lossis lub tank cia siv.
Nyob rau hauv luv luv, cov tshuaj muaj pes tsawg leeg, kev faib ua feem thiab batching txoj kev ntawm refractory mortar muaj ib qho tseem ceeb cuam tshuam rau nws cov kev ua tau zoo thiab siv los. Thaum lub sij hawm tsim khoom thiab siv, nws yog ib qho tsim nyog yuav tsum ua raws li cov kev cai nruj me ntsis kom ntseeg tau cov khoom zoo thiab kev ua tau zoo.
