What are the coloring methods of ceramic permeable bricks?
There are many color choices for water-permeable bricks, which also make the paved areas more beautiful while achieving water permeability, water absorption, compression resistance and noise reduction.So, what method is used to make the permeable bricks have multiple colors?
Dyeing method: It is a cheaper material. Adding low-iron mud to make lime powder into yellow and other products is a method of overall coloring. Sizing method: mainly by special bonding, flux, filler, coloring agent, etc. Permeable bricks of ceramic soil. Sometimes used as binders in organic materials of soil, added to enhance their ability to combine soil and body surface.
Glazing method: a special glaze suitable for the thermal expansion coefficient of ceramic permeable bricks, applied to the surface of the brick to form a special colored glaze on the surface of the brick.
Surface dyeing method: The metal salt solution is dyed with some ceramic infiltration bricks, and the surface can be coated with a few millimeters deep to form a solid and specific color after roasting.
Surface coating method: This method is sufficient for the body extrusion process in the body, this paper will become a good surface coloring sludge evenly extruded through a special gear at 5-10 mm in the coating of the body coating Focusing on the combination of the solid layer of roasting and bad body, the surface specific color is formed.
Roasting dyeing method: This method has a great change in the atmosphere of the ceramic ventilated brick roasting kiln, and presents different coloring methods in the blanking colorant. For example, in a reducing atmosphere, the brick is baked.
In short, no matter what color is used, the coloring of ceramic permeable bricks is to enhance their appreciation, thereby increasing sales, improving efficiency for the enterprise, adding beauty to the building, and making the building no longer monotonous.
