Yuav ua li cas cais cov kua qaub, alkali thiab nruab nrab ntawm cov ntaub ntawv refractory
Acid yog silicon oxide raws li cov khoom ntawm cov khoom siv refractory, cov khoom yog silica thiab av nplaum refractory cib thiab castables, xws li silicon bricks, lub teeb silicon cib, acid-resistant bricks, av nplaum cib, acid castables, acid teeb castables, acid cov khoom yog tsuas yog siv. hauv coke qhov cub, iav melting kiln kiln hauv ob sab phlu. Av nplaum cib tsis muaj zog acidic, tab sis zoo thermal shock, feem ntau siv dav.
Alkaline yog magnesium oxide, calcium oxide raws li cov khoom tseem ceeb ntawm cov ntaub ntawv refractory, cov khoom yog magnesium cib, ncaj magnesium cib, magnesia alumina spinel cib thiab muaj magnesium oxide 80 ~ 85 lossis ntau dua amorphous castable, alkaline cov ntaub ntawv muaj zog tiv taus slag thiab hlau, refractories acidic tshaj li cov khoom nruab nrab yog siab dua, alkaline cov khoom yog tsuas yog siv rau alkaline cua kiln hauv ob sab phlu, xws li rotary kiln, converter thiab lwm yam. Magnesia dolomite refractory bricks nyob rau hauv alkaline refractory cov ntaub ntawv yog cov alkaline, thiab chrome-magnesia thiab magnesia olivine refractory cib los yog castable thiab spinel composites muaj zog alkaline refractory cov ntaub ntawv.
