24 color waterproof sintered colored sand

Colored sand is now divided into natural colored sand, sintered colored sand, temporary dyed colored sand and permanent dyed colored sand. Its characteristics are: bright color, acid and alkali resistance, UV resistance and no fading. Natural colored sand: it is crushed from natural ore and does not fade, but there are many impurity colors; Temporary dyed colored sand: bright color and easy to decolorize.

Decorative colored sand: it is selected and processed without any dyes. It is non-toxic, tasteless, pollution-free

It has the characteristics of corrosion resistance, acid and alkali resistance, exposure resistance and no discoloration. It is used for decoration of families and buildings. The color is long-lasting and pollution-free.

The process method of sintering colored sand is composed of four steps: stirring, preheating, calcination and cooling. It is characterized in that in the preheating and calcination steps, the mixed materials are preheated and calcined in the preheating drum and calcination drum with the hot air provided by the hot air stove. The invention has the following advantages and positive effects:

characteristic

1. The invention takes coal as fuel and saves energy.

2. Because pure constant temperature hot air is used to calcine the materials, the cleanliness of the materials is guaranteed.

3. The diameter of the drum can be adjusted according to the material output, which ensures the supply of output.
