NoneInorganic powder materials have a wide range of applications in many fields. However, due to their high surface activity, they are prone to agglomeration, which can lead to a decline in performance. For example, it is difficult to achieve high uniformity and high dispersion during the molding process, resulting in a decrease in the performance of the final sintered material and failing to fully utilize its advantages.

Modified coating equipment can effectively improve the performance of inorganic powders. First, it can enhance the dispersion of inorganic powders. The large specific surface area of powder particles, the different surface bonding states, electronic states, and incomplete coordination provide favorable conditions for surface modification of inorganic powder particles using chemical methods. By methods such as surface deposition, chemical coating, and mechanochemical modification, a layer or multiple layers of "coating" or "film" can be formed on the particle surface, making the particle surface organic and thus changing the dispersion of inorganic powders. "Coating" or "film" makes the particle surface organic, thereby changing the dispersion of inorganic powders.

Secondly, modified coating equipment can also change the optical properties and other characteristics of inorganic powders. For example, inorganic coating methods can improve the whiteness, particle shape, wear resistance, aging resistance, optical properties, and pigment properties of the powder..

Modified coating equipment has important applications in multiple fields:

1. In the field of luminescent materials

The surface coating of phosphors can solve the problem of performance decline caused by electrical and surface chemical activity, improving luminescent performance and enhancing dispersion.

2. In the field of nanomaterials

Inorganic powder materials have high surface activity and are prone to agglomeration, making it difficult to achieve high uniformity and high dispersion during the molding process, which affects the performance of the final sintered material. Coating a layer of inorganic or organic polymer material on the surface of nanomaterials can improve their dispersion performance.

3. In the field of ceramics

Ceramic matrices are generally high-temperature synthetic ceramic materials, with good consistency on the particle surface, making it easier to process and obtain better materials with consistent surface coating. The addition of advanced ceramic components in ceramic matrix composites expands their application range beyond many conventional materials and demonstrates superior comprehensive performance. In applications, the most important technology is the modification and coating of ceramic powder materials, mainly addressing the severe agglomeration of ultrafine powders or whiskers and the poor affinity with the materials being compounded.

4. In the field of pearlescent pigments

Coating metals such as copper, iron, zinc, silver, or metal oxides like nickel oxide and tin oxide on the surface of mica can improve the color of pearlescent pigments. By coating the pearlescent pigment matrix and then modifying the coated pearlescent pigment with surface modifiers, the polarity of the pearlescent pigment matrix can be changed, allowing the pearlescent pigment to dissolve and mix uniformly in organic solvents, making it less likely to settle and layer.
