ZIBO SK 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. ZIBO SK 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. Category Air setting refractory mortar Grade-23 Grade-26 Thermalâ??hardness refractory mortar Grade-28 Grade-30 Features High bonding performance for bricks engineering Excellent sealing capability, resistance to erosion High refractoriness under load Outstanding efficiency in reducing the slag Ensure well-sealed joints for convenient installation Consistency and bonding effectiveness Typical Applications Necessary auxiliary materials for insulating Firebricks in the furnace lining
