Acid resistant castable tseem hu ua refractory castable, uas yog ib qho ntawm cov khoom siv refractory, thiab tuaj yeem tiv taus cov kua qaub yaig, uas yog siv dav hauv cov hlau tsis muaj hlau, tshuaj lom neeg kev lag luam, chimney, thiab lwm yam. castable muaj cov ntsiab lus siab dua ntawm kev khi tus neeg sawv cev thiab ya raws thiab ntau dua liquidity. Unshaped refractory muaj ntau daim ntawv thov thiab tuaj yeem siv los ntawm kev nchuav lossis ramming raws li kev xaiv cov kev pabcuam rau cov ntaub ntawv thiab cov neeg sawv cev khi.
Acid resistant castable manufacturing txheej txheem yog yooj yim tsis muaj cov cuab yeej tshwj xeeb. Acid resistant castable muaj lub zog txhua yam thiab zoo. Nws yog ib qho yooj yim los tsim los ntawm txoj kev ntawm pouring. Acid resistant castables tuaj yeem siv ncaj qha rau hauv engineering yam tsis muaj hluav taws xob. Thiab acid resistant refractory castable tuaj yeem tiv taus acid nruab nrab corrosion ntawm 800 ~ 1200 ℃ tuaj yeem nchuav hu ua refractory acid resistant castable. Refractory acid resistant castable yog tsim nrog dej iav li binder, acid los yog alkali acid refractory li aggregate thiab hmoov, thiab ib tug me me coagulant. Txawm li cas los xij, xws li castings tsis tiv taus corrosion los ntawm alkali, hydrochloric acid, hydrofluoric acid thiab roj siab.
Cov ntsiab lus ntawm acid resistant castable yog: acid-resistant refractory aggregate (60-70%), hmoov (30-40%), thiab sodium fluorosilicate (13% -16%) ua tus neeg sawv cev hardening.
