Stearic Acid Coated Silver Powder Equipment - Tungkula T-MIX
Stearic acid-coated silver powder can significantly improve the dispersion of silver powder and has a positive impact on the conductive properties of conductive silver paste.
When the silver powder is not coated, there may be a certain degree of oxidation or contaminants on the surface. These substances will increase the mutual adsorption force between silver powder particles and lead to the aggregation of silver powder. Such aggregation phenomenon will reduce the dispersion of silver powder in conductive silver paste and affect the stability and uniformity of conductive properties.
By coating with surfactants such as stearic acid, a protective film can be formed on the surface of silver powder to effectively reduce the interaction between silver powder particles. In this way, the silver powder is more easily dispersed and evenly distributed in the conductive silver paste, thereby improving the stability and uniformity of the conductive properties.
In addition, stearic acid coating can also provide better antioxidant and corrosion resistance, help protect silver powder from oxidation or chemical reactions in the environment, and further improve the long-term stability of conductive properties.
Tungkula powder surface coating modification equipment T-MIX is a kind of equipment specially used for stearic acid coating silver powder. It is designed to improve the dispersion of silver powder to ensure it is evenly dispersed in the substrate during application.
T-MIX usually consists of the following main components:
Coating Room: The coating room is the main space where surface coating is performed. It usually has a closed structure to prevent outside contaminants from entering. In the coating chamber, coating materials such as silver powder and stearic acid are mixed and sprayed onto the surface of the silver powder.
Spray System: The spray system is used to spray stearic acid or other coating materials evenly on the surface of silver powder. Spray systems usually include components such as nozzles, gas supplies, and liquid supplies to ensure a uniform and stable spray.
Control System: The control system is used to monitor and control the entire coating process. It can adjust parameters such as spray volume, spray speed and spray pressure to ensure the stability and consistency of the coating process.
Using Tungkula powder surface coating modification equipment T-MIX to coat silver powder with stearic acid can significantly improve the dispersion and stability of silver powder. As a surfactant, stearic acid can coat the surface of silver powder to form a thin film, reducing the mutual adsorption force between silver powder particles, making it easier to disperse the silver powder in the substrate and providing better antioxidant properties. and corrosion resistance.
