Color sand is divided into natural color sand, sintering color sand, temporary dyeing color sand and permanent dyeing color sand. Its characteristics are: bright color, acid and alkali resistance, UV resistance, no fading. Natural color sand: it is made of natural ore, not fade, but more impurity color; Temporary dyeing sand: bright color, easy to decolorize.

　　Natural colored sand is used in building materials;

　　In addition to the four-sided board and block stone, the exterior wall can also be made of natural colored sand in any shape. Holes and grooves are processed on the surface of natural colored sand, which makes the surface of outer wall and inner wall show special optical and visual effects. The natural colored sand can make the whole building more grand and the building structure more three-dimensional, such as adding horizontal foot line, protruding frame and column, etc. in the front of the building, the artistic effect of the building can be achieved.

　　If we observe the total cost of various building materials for 30 years or more, we can see that natural colored sand is not higher than the total cost of other artificial building materials. The same conclusion is drawn from several different and unrelated investigations. Compared with high investment cost, the long-term low maintenance cost and long service life have more advantages in the price of natural color sand, and the cost of cleaning and maintenance is lower.

　　Natural colored sand is warm in winter and cool in summer, which is conducive to energy conservation

　　Natural color sand has good thermal conductivity and high heat storage capacity. As building materials for the external wall of the house, it can insulate the sunlight in summer, prevent the indoor energy consumption of about 100-150kwh / m2, while the energy consumption of heating and cooling in the glass wall buildings is 300-700kwh / m2.

　　The natural color sand products are: black series color sand, red series color sand, yellow series color sand, white series color sand, green series color sand, blue color sand series, gray series color sand, etc.
