colored pavement brick production process

1 color surface material: the colored cement or white cement, pigment powder and sand composition at a certain mixing ratio, the QM-80-type ball mill grinding from 10 to 15 minutes. Material to ensure product surface color finish and color uniformity.
(2) Primary materials: from the powder, a small amount of waste rock and trace ordinary cement curing agent, according to the mixing ratio of raw materials through the wheel grinding machine, stir composition, Concrete mixing plant in powder, waste rock larger dosage, cement, mixed with a curing agent small amount, it will directly affect the quality mixing intensity of color brick road quality. 3 compression molding: hydraulic brick machine is equipped with four tables for four workers cyclic operation, each set of molds. Before adding colored surface layer material (quantitative), then add material to the mold box grass flat, the high-pressure line with molded brick machine, available for immediate release, stacking, conservation. Because product specifications are different, so there are changes in the molding pressure concrete block machine can be adjusted). Just to change the mold, can suppress a variety of shapes and sizes of colored pavement brick, square brick, grass brick, slope protection brick, standard brick and other products. Taiwan shift production 2000 ~ 7000.
4 Products conservation: Products available for immediate release, stacking, The Nature Conservancy, two weeks after filing the factory. Steam curing twenty-four hours either.
