Production Process



Select 8-160 mesh clean quartz sand with no impurities (strictly control the moisture content) 90-98 parts, inorganic pigment 1-8 parts, enamel fusing agent 1-2 parts; mix the inorganic pigment 1-8 parts and fusing agent 1-2 parts to form a uniformly fine powder with a uniform particle size, and then mix the quartz sand 90-98 parts together evenly. High-temperature sintering is performed at a temperature of 350-900°C, and the sintering time is 10-15 minutes. This can obtain a colored enamel sintering sand.

Our factory has been engaged in the production and sales of colored sand for more than ten years. We have always been committed to the research and development of the coating field, and have solved the color limitations and color difference problems of colored sand through learning, research, and repeated experiments. We have successfully produced "colored enamel sintered sand".

Sintered sand has excellent weather resistance, adhesion, chemical stability, and good UV resistance.
