High-Temperature Sintered Fade-Proof Colored Sand

Product Introduction 

Sintered colored sand is made by using natural sand particles such as quartz and limestone as the main aggregate, adding a colored inorganic coating composed of inorganic silicate binders, inorganic high-temperature colorants and active oxide binders, and then sintering it at high temperature.

Product Advantages

1.Excellent physical properties: High-temperature sintering creates a dense crystalline structure in the sand particles, resulting in high strength and hardness, wear resistance, and resistance to breakage. The production process is controllable, producing regularly shaped sand particles with uniform size distribution, exhibiting good flowability and filling properties.

2.Strong chemical stability: Highly resistant to acids and alkalis, with excellent freeze resistance and water resistance.

3.Good color performance: A rich variety of colors can be produced by adding different additives, resulting in uniform, long-lasting, and vibrant colors that are resistant to fading.

4.Environmentally friendly: Made from natural sand, it contains no harmful substances, is harmless to the environment and human health, and is recyclable.

Main specifications

1.Production process.It generally consists of four steps: stirring, preheating, calcination, and cooling. After the raw materials are mixed and stirred in a certain proportion, they are preheated and calcined in a preheating drum and a calcination drum using hot air provided by a hot air furnace, and finally cooled to produce the final product.

2.Common particle sizes (mesh): 8-12 mesh (coarse), 12-20 mesh, 20-40 mesh (most common), 40-80 mesh (fine), 80-120 mesh (extremely fine).

3.Color: Standard color card provided; custom colors are usually available.

4.Packaging: 25kg/bag, ton bags, etc., or can be repackaged according to customer requirements.
