Planetary Centrifugal Mixer in Silver Paste Defoaming Application

Silver paste is a high-performance conductive material widely applied in electronic devices and solar cells. However, bubbles are easily generated during its preparation, which will directly reduce the conductive performance of silver paste and cause uneven coating surfaces, damaging the overall product quality. SMIDA planetary centrifugal mixer is a professional equipment for material defoaming, and its application in silver paste preparation has become a key and essential process step.

The working principle of SMIDA planetary centrifugal mixer is to realize efficient defoaming in a vacuum environment with its unique stirring structure. The low air pressure in the vacuum state makes the bubbles in the silver paste expand and escape easily, and the planetary centrifugal stirring of the equipment accelerates the floating and gathering of bubbles, which are then adsorbed and discharged by the vacuum system, achieving a thorough defoaming effect.

In silver paste production, silver powder and binder are mixed to form slurry, and the high viscosity of the slurry makes it difficult for internal gas to escape naturally, leading to bubble formation. After defoaming treatment by SMIDA planetary centrifugal mixer, the bubble problem of silver paste is effectively solved, and the product quality is comprehensively improved, with the following core advantages:

Beyond silver paste defoaming, SMIDA planetary centrifugal mixer also has extensive applications in the processing of other high-viscosity materials. It is widely used for defoaming resin, glue and other materials that are prone to bubble generation during preparation, effectively improving the internal structure and performance stability of these materials, and upgrading the overall quality of finished products.
