Dab tsi yog Hom Thiab Kev Ua Haujlwm Ntawm Binders Siv Rau Tundish Gunning

Lub binder siv rau tundish gunning khoom yog tsuas yog siv nyob rau hauv lub low-temperature ci txheej txheem. Los ntawm kev kho thiab carbonization ntawm cov ntawv khi, cov khoom siv phom muaj qee lub zog thiab ua tau raws li qhov yuav tsum tau siv thaum siv kub. Binders muab faib ua ob pawg: low-temperature binders thiab nruab nrab kub binders. Tsawg-kub binders ua lub luag haujlwm hauv kev teeb tsa. Qhov nruab nrab kub binders feem ntau xyuas kom meej tias cov txheej txheem ua hauj lwm ntawm tundish gunning khoom muaj lub zog txaus tom qab ci ntawm qhov nruab nrab kub ntawm 1100 degree, thiaj li hais tias nws muaj peev xwm tiv taus lub scouring ntawm molten hlau thiab zam cov pa phem los ntawm kev koom tes ntawm refractory cov ntaub ntawv nyob rau hauv molten. hlau. Qhov nruab nrab kub binders muaj xws li borax, sodium fluoride, silica hmoov, thiab lwm yam
