Hom refractory casting khoom

Refractory castables feem ntau yog muab faib raws li qhov loj ntawm qhov porosity, xaiv binder los yog kev sib khi txoj kev, hom kev sib sau, thiab kev tsim kho.
1. Raws li qhov porosity, nws tuaj yeem muab faib ua tuab refractory castable thiab rwb thaiv tsev refractory castable;
2. Raws li kev faib tawm ntawm kev sib txuas, cov khoom siv hluav taws xob tuaj yeem muab faib ua plaub hom: hydrated bonded refractory castables, chemically bonded (xws li polymerized) refractory castables, hydrated thiab polymerized refractory castables (feem ntau tsawg cement bonded refractory castables), thiab bonded agglomeration. refractory castables.
3. Raws li cov haujlwm tshwj xeeb ntawm cov binders thiab qee cov ntaub ntawv, lawv tuaj yeem muab faib ua 7 pawg hauv qab no:
(1) Clay bonded refractory castable;
(2) Ultra nplua hmoov (xws li silica fume) ua ke nrog refractory castable;
(3) Cement bonded refractory castable;
(4) Chemical bonded refractory castable;
(5) ρ- Al2O3 (hydrated Al2O3) ua ke nrog refractory castable;
(6) Tsawg cement bonded refractory castable;
(7) Silica thiab aluminium sol (sol gel) bonded refractory castables.
4. Raws li kev sib xyaw ua ke ntawm cov khoom siv raw, cov khoom siv refractory castables tuaj yeem muab faib ua oxide raws li refractory castables, uas tsis yog oxide raws li refractory castables, thiab composite refractory castables. Oxide raws li refractory castables tuaj yeem muab faib ntxiv rau cov uas tsis yog alkaline refractory castables thiab alkaline refractory castables.
5. Raws li txoj kev tsim kho, refractory castables tuaj yeem muab faib ua ob pawg: kev vibration siv refractory castables thiab nws tus kheej ntws refractory castables.
6. Raws li seb lub refractory castables muaj cov cement lossis CaO cov ntsiab lus, lawv tuaj yeem muab faib ua plaub pawg: zoo tib yam refractory castables, qis cement refractory castables, ultra-low cement refractory castables, thiab cementless refractory castables.
