The colored sand is now divided into natural colored sand, sintered colored sand, temporary colored sand and permanent colored sand. Its characteristics are: bright color, acid and alkali resistance, UV resistance, non-fading. Natural colored sand: It is made of crushed natural ore, which does not fade but has many impurities; Temporary colored sand: bright color, easy to decolor.

Natural colored sand is made of marble or granite ore through multiple processes such as selection, crushing, crushing, grading and packaging.
The process method for sintering colored sand is composed of four steps: mixing, preheating, calcination and cooling. It is characterized in that: in the preheating and calcination steps, the hot air provided by the hot air furnace is used to preheat and calcine the mixed materials in the preheating drum and calcination drum.

Colored sand is dyed by fine quartz sand and has the characteristics of non-fading. Colored sand makes up for the disadvantages of natural color sand, such as non-bright color and few color varieties. The color is firm, durable and non-fading.
Folding characteristics

1. The particle size of various specifications is uniform, the particles are round, and can be graded arbitrarily.
2. The color is colorful, lasting and beautiful, and environmentally friendly.
3. Good compatibility with various resins.
4. Acid resistance
5. Alkali resistance
6. Resistance to chemical solvents
7. Hot water resistance

Folding purpose
Dyed colored sand is mainly used for all kinds of colored epoxy floor, real stone paint, various architectural coatings, sandstone board, ABS modified asphalt felt, waterproof coiled material, handicrafts, etc. It has bright colors, strong weather resistance, wear resistance, acid and alkali resistance, anti-slip, seamless, high-grade and beautiful, and is mainly used for decoration, craft and other industries.
