SMIDA planetary centrifugal mixer: uniform and foam free mixing scheme of epoxy resin and fluorescent powder

The mixing quality of epoxy resin and fluorescent powder directly determines the performance of light-emitting devices and identification materials. Traditional stirring can easily lead to the aggregation of fluorescent powder clusters, insufficient encapsulation of epoxy resin, and a large amount of residual bubbles can cause uneven luminescence and brightness attenuation, seriously affecting the reliability and aesthetics of end products. ​

1、 Epoxy+Fluorescent Powder Mixing: Comparison of Traditional Equipment and SMIDA Effect
The SMIDA planetary centrifugal mixer utilizes the synergistic effect of "centrifugal extrusion defoaming+multidimensional shear dispersion" to accurately match the mixing characteristics of epoxy and fluorescent powder, with significant advantages in effectiveness

2、 Core application scenarios of epoxy+fluorescent powder mixture
The SMIDA mixer has been deeply adapted to the mainstream industry demand for mixing epoxy and fluorescent powder, solving practical production pain points:
1. LED packaging field
Epoxy fluorescent powder adhesive used for LED bead packaging, after being stirred by SMIDA, the fluorescent powder is evenly distributed in the epoxy without any refraction deviation caused by bubbles. The color temperature consistency of the bead emission is improved, the brightness attenuation rate is reduced, and the service life is extended. ​
2. Fluorescent labeling and warning field
Epoxy fluorescent powder coating is used for road fluorescent signs and safety warning signs. After mixing, there is no agglomeration or bubbles. The coating emits uniform light and is wear-resistant after drying. The warning effect is more stable in low light environments and is suitable for safety scenarios such as traffic and mining. ​
3. Optical component manufacturing field
Epoxy fluorescent powder composite materials are used for optical lenses and light guide plates. SMIDA stirring can ensure uniform optical properties of the materials, avoid light scattering and decreased transmittance caused by uneven composition, and improve the imaging quality and light guide efficiency of optical components. ​
4. Decorative and artistic coatings field
After mixing epoxy fluorescent decorative coatings (such as starry sky roofs and fluorescent walls), the fluorescent powder is evenly distributed, there are no coating defects caused by bubbles, the luminous effect is natural and coherent, and it is tightly combined with epoxy, improving its scrub resistance. ​

3、 Exclusive hybrid design highlights
Fluorescent powder directional dispersion structure: The stirring equipment adopts a combination of planetary revolution and rotation to achieve shear mixing according to the characteristics of the fluorescent powder, avoiding the failure of the fluorescent powder caused by excessive stirring and ensuring uniform dispersion. ​
Epoxy viscosity adaptation system: automatically adjusts parameters such as speed and vacuum degree according to changes in epoxy viscosity, ensuring mixing effect while avoiding local overheating during high viscosity epoxy mixing, and ensuring stable material properties. ​
Visual mixing window: The equipment is equipped with a visual dustproof window, which can observe the mixing process and ensure consistent mixing quality for each batch. ​
