Phosphate - Bonded Refractory Castables

I produced the phosphate refractory castable is high-quality high-alumina clinker, phosphoric acid-based materials, plus a number of blending materials from the preparation. Good heat resistance, high plasticity, high temperature, compression, flexural strength of a high heat unshaped refractory, widely used in building materials, metallurgy and cyclone steam boiler bottom
Solution pool and lining and other parts.
 
I am in the development of phosphate refractory castable after a long time R & D ratio, summed up the production experience.
First, the trapped material, about refractory aggregate and powder and binder dosage of about 3/5 first mixed evenly into the silo or trapped material site, covered with plastic sheeting
, To prevent the evaporation of cement; while not in contact with water, the temperature should be greater than 15 ° C. Set aside for some time, so that cement and refractory aggregate and powder
Of the metal fully reacts, releasing hydrogen.
Second, the use of ceramic ball mill grinding or with strong acid (such as hydrochloric acid, etc.) and the use of magnetic materials such as washing method of powder, less into or exclude metals and other impurities.
Third, reduce the amount of binder, inhibitor or increase the molding pressure. Once the pressure at the time of molding is reached, the strength after conditioning can be achieved.
