Abstract

A kind of manufacturing method of ceramic face brick from recycled aluminum slag which uses the aluminum slag from stabilizing procedures to produce the face brick, the steps include: a. mix the recycled aluminum slag with water and comminute to isolate the aluminum particles from non-metal material b. proceed the wet vibration process to bolt the coarse-grained with high aluminum density from fine particles with low aluminum density; the coarse-grained is recycled for aluminum production c. adjust the solid/liquid ratio for fine aluminum slag particles and water between 1:1 to 1:5, and proceed the heating and agitation for stabilization so that the active components, such as the aluminum, aluminum nitride and aluminum carbide, within the pulp can be hydrolyzed and erased. The temperature of aluminum pulp is kept at 80 to 100 degree in Celsius and proceeds the heating and agitation simultaneously for 12 to 48 hours d. after the stabilization, the aluminum pulp is proceeded the gravitating process to get rid of the chloride of clarified water layer. e. the stabilized aluminum pulp after step 4 is mixed with fixed ratio, 50%-90% for stabilized pulp and 10%-50% plasticizer and 0%-30% solutizer ; f. use the mixture for the forming process g. the burning process is at the temperature from 1100 to 1300 degrees in Celsius and the ceramic face brick is produced with hydrophilic rate greater than 6%.
