Details

Descriptions

Zhongzi refractory mortar is a new kind of paste-like bonding material which is formed particularly from specially sorted powder made from the identical raw materials and classification temperatures in light with the brick utilized in furnace and their refractory grades. During the process of production, it undergoes chemical reaction and stirring-up with added inorganic bonding agent and additives. Zhongzi refractory mortar can be classified into four categories according to its service temperature in normal circumstances and they must be used to support the lightweight mullite brick subject to the same class.
