增孔剂对镁橄榄石质隔热耐火材料结构和性能的影响

Effect of Pore-agent on Structure and Performance of Forsterite Insulating Refractory

采用天然镁橄榄石和镁砂为原料 ,以粘土为结合剂 ,在以泡沫法制备镁橄榄石质微孔高强耐火材料工艺的基础上 ,通过添加增孔剂碳黑和碳酸镁微粉 ,分析其对试样结构和性能的影响。实验结果表明 :加入碳黑的试样 。

The micropore and high strength forsterite refractory was prepared by foaming method,using natural forsterite and magnesite as raw materials,and the clay as binder.The effect of black carbon and magnesium carbonate fine particles on structure and performance of the samples was investigated.The results show that the samples added into black carbon have a lot of micropore,which uniformly distributes in them.
