水玻璃结合不烧铝镁砖龟裂的分析探讨

The Analysis and the Discussion of the Cracks of the Unfired Aluminum-magnesia Bricks Bound by the Water Glass

根据实验室研究和工业试验,水玻璃结合不烧铝镁砖龟裂与水玻璃摸数、波美度、泥料颗粒组成、废砖反复加入量、干燥时间等因素有关。最佳工艺参数为n=2.45～2.65,B=47～50Be,泥料粒度应控制大于3mm和小于或等于0.088mm部分均占36％左右,干燥时间为16h,废砖不宜集中使用。

This paper find out that the craks of the unfired aluminum-magnesia bricks bound by the water glass relate to the moduli and baume degrees the water glass, the grain components of the mixture of aluminummagnesia, the quantities of the water bricks added in to the mixture, the drying time according to the industrial experiments and the laboratory studies. The optimum technological parameters are: n=2.45～2.65, B=47～50 Be, the mixture grain controlled>3mm and ≤0.088mm parts 36% about, the drying time 16h, and the waste brick may not be used in amass.
