高强耐碱砖
Hiah strenath alkali resistant bricks
高强耐碱砖 是由低铝耐火粘土为主要原料烧制而成,具有在水泥窑系统中耐碱侵蚀特性的粘土质耐火砖。该产品采用科学的高温陶瓷化晶相结构,封闭了产品开口气孔通道,从而达到抗化学侵蚀和防止物料渗透沉积裂解的目的。为此该系列产品在水泥窑预热系统中得到了良好应用
Hiah strenath alkali resistant bricks is made of low alumina refractory clay as the main raw material It is clay refractory brick with alkal resistance in cement kiln system.The product adopts scientific high temperature ceramic crystal phase structure, sealing the product's opening and porosity channel,so as to achieve the purpose of resisting chemical erosion and preventing the material from penetrating and deposition cracking.Therefore,the products have been well used in the preheating system of cement kiln.
