Tsawg cement castables cov ntaub ntawv yog cov khoom siv amorphous refractory uas tau siv dav hauv xyoo tas los no. Lawv feem ntau suav nrog aluminium silicate, magnesia, thiab silica. Cov ntsiab lus ntawm cov cement castable yog li 5%, thiab qee qhov txawm tias txo qis rau 1% ~ 2%. Lub hom phiaj ntawm kev txo cov cement ntau npaum li cas yog txhawm rau txhim kho qhov hluav taws kub ntawm cov castables. Kev npaj cov txheej txheem ntawm cov cement refractory castables yog nruj, yog li muaj ntau yam cuam tshuam rau nws cov kev ua tau zoo, yog li koj yuav tsum tau them sai sai rau thaum siv nws.
Tsawg-cement castable yog cov khoom siv high-tech refractory tsim los ntawm cov castables zoo tib yam siv cov ntsiab lus rheology, qhov ze tshaj plaws packing theory thiab ultra-fine hmoov technology. Nws muaj cov yam ntxwv ntawm cov porosity tsawg, me me pore loj, siab ceev, zoo ntim stability, siab zog thiab me me ntawm cov dej ntxiv, thiab overcomes qhov txo qis ntawm lub zog ntawm cov castables zoo tib yam ntawm 800 mus rau 1200 degree, thiab raws li qhov kub thiab txias nce. nce qhov kub thiab txias, qhov thermal shock tsis kam ntawm lub tshuab hluav taws xob lub cev tuaj yeem ua tau ntau dua ob npaug.
Cov yam ntxwv cuam tshuam rau kev ua haujlwm ntawm cov cement castables tsawg
1. Kev cuam tshuam ntawm aggregates: Aggregates yog ib qho tseem ceeb ntawm cov cement castables tsawg thiab muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm cov cement castables tsawg. Hom, particle loj, gradation, puab thiab nto lub xeev ntawm aggregates tag nrho yuav cuam tshuam cov fluidity, compressive zog thiab durability ntawm tsawg cement castables.
2. Kev cuam tshuam ntawm cov tshauv ya: ya tshauv yog cov khoom siv uas nquag siv thiab muaj qee yam cuam tshuam rau kev ua haujlwm ntawm cov cement castables tsawg. Tus nqi tsim nyog ntawm ya tshauv tuaj yeem txhim kho qhov fluidity ntawm qis-cement castables, txo los ntshav thiab txhim kho corrosion kuj. Txawm li cas los xij, yog tias cov hmoov tshauv ya ntau dhau lawm, lub zog ntawm cov cement castables yuav txo qis.
3. Kev cuam tshuam ntawm slag: Slag yog cov khoom siv nquag siv uas tuaj yeem txhim kho lub zog, durability thiab corrosion kuj ntawm low-cement castables. Txawm li cas los xij, yog tias cov slag ntau dhau lawm, qhov fluidity ntawm cov cement castables tsawg yuav txo qis.
4. Kev cuam tshuam ntawm admixtures: Admixtures tuaj yeem kho thiab txhim kho qhov kev ua tau zoo ntawm cov cement castables qis, xws li txhim kho fluidity, txo los ntshav, txhim kho kev ua tau zoo thaum ntxov, thiab lwm yam. Txawm li cas los xij, hom thiab ntau npaum li cas ntawm cov khoom sib xyaw yuav tsum tau tswj nruj me ntsis, txwv tsis pub nws. yuav cuam tshuam rau kev ua haujlwm ntawm cov cement castables tsawg.
5. Kev cuam tshuam ntawm kev kho mob: Cov kev kho mob ntawm cov castables no muaj kev cuam tshuam zoo rau lawv cov kev ua tau zoo. Qhov tsim nyog kho qhov kub thiab txias, av noo thiab lub sijhawm tuaj yeem ua kom ntseeg tau tias cov cement castables tsis muaj dej txaus thiab tawv tawv, txhim kho lawv lub zog thiab kav ntev. Yog tias tsis tswj xyuas kom zoo, kev ua haujlwm ntawm cov castables no yuav txo qis.
6. Kev cuam tshuam ntawm kev tsim kho tshuab: Kev tsim kho tshuab kuj muaj txiaj ntsig zoo rau kev ua haujlwm ntawm cov cement castables. Piv txwv li, nchuav ceev, txoj kev vibration, kev tsim kho lub sijhawm, thiab lwm yam yuav cuam tshuam rau qhov ntom ntom, sib xws thiab lub zog ntawm cov cement castables tsawg.
