Solving Heat Dissipation Challenges: ZYE Vacuum Planetary Mixer Overcomes Liquid Metal-Silicone Oil Mixing Bottlenecks, Empowering High-End Manufacturing
In cutting-edge fields such as advanced material synthesis, electronic packaging, and thermal management, composite systems of liquid metal and silicone oil show broad application prospects due to their combination of the high thermal conductivity and electrical conductivity of liquid metals with the excellent lubricity, sealing properties, and chemical stability of silicone oil.
Liquid metals (primarily composed of low-melting-point metals like sodium, potassium, gallium, bismuth, and their alloys) typically have high density and surface tension, and exhibit significant density differences and compatibility issues with silicone oil. Traditional mixing equipment struggles to achieve uniform and stable mixing of the two, often leading to problems like stratification and agglomeration, which severely impact the performance of the composite system.
Main Applications Of Liquid Metal-Silicone Oil Composite Systems In Thermal Management Materials:
- Electronic Device Heat Dissipation: Suitable for high-density heat-generating components like chips, CPUs, and power devices. The composite system can serve as thermal grease, thermal pads, or liquid cooling media, rapidly conducting heat away and preventing device overheating.
- New Energy Equipment Thermal Management: Can be used in heat dissipation modules for power batteries and energy storage equipment. The uniformly dispersed liquid metal enhances heat dissipation efficiency, ensuring stability and service life of the equipment in high-temperature environments.
- Precision Electronic Packaging Heat Dissipation: Meets thermal management needs during electronic packaging, offering both thermal conductivity and sealing properties. It can transfer heat from within the package while protecting components from external environmental influences.
However, the mixing process of liquid metal and silicone oil faces multiple technical bottlenecks during research and development. From a material characteristics perspective, liquid metal density generally ranges from 6-7 g/cm³, while silicone oil density is only 0.9-1.0 g/cm³. This significant density difference causes liquid metal to easily settle and silicone oil to float during mixing, making it difficult to form a stable dispersion system. The high surface tension of liquid metal makes it resistant to breaking into fine droplets within silicone oil, tending instead to agglomerate into large particles, reducing the uniformity of the composite system. Simultaneously, the viscosity of silicone oil hinders the diffusion of liquid metal, further increasing mixing difficulty.
Traditional mixing equipment, such as paddle stirrers and high-speed dispersers, often rely on single-direction shear or impact forces, resulting in an uneven mixing force field. They struggle to overcome the interfacial tension between materials and are prone to creating local dead zones. This leads to poor stability of the mixed system, rapid stratification after standing, and failure to meet the requirements for material performance consistency in practical applications. Therefore, mixing equipment capable of providing strong shear, high dispersion, and no dead zones is needed to achieve deep integration of liquid metal and silicone oil. In practice, the ZYE vacuum planetary mixer, leveraging its unique mixing principle and exceptional performance, successfully overcomes these technical challenges by uniformly blending the two difficult-to-mix liquid materials into a paste form.
Technical Advantages Of The ZYE Planetary Vacuum Mixer
As a high-efficiency mixing device, the core advantages of the ZYE planetary vacuum mixer lie in its unique planetary motion structure and multi-dimensional mixing force field design, which specifically address the challenges of mixing liquid metal and silicone oil.
（一） Planetary Motion Enables Uniform Mixing Without Dead Zones
The ZYE planetary mixer pharmaceutical employs a compound motion mode of "revolution + rotation" for mixing. The rotating cup revolves around the central axis of the device while simultaneously rotating at high speed around its own axis. This motion pattern creates complex convective, shear, and diffusive movements of the material within the mixing vessel, eliminating any mixing dead zones. For liquid metal and silicone oil with significant density differences, the centrifugal force generated by the revolution pushes the material to flow along the vessel wall, preventing the settlement of liquid metal. The strong shear force generated by the rotation effectively breaks apart liquid metal agglomerates, dispersing them into fine droplets uniformly distributed within the silicone oil matrix, fundamentally solving the problems of stratification and agglomeration.
（二）Strong Shear And High-Pressure Kneading Enhance Material Compatibility
The poor compatibility and weak interfacial bonding force between liquid metal and silicone oil directly affect the stability of the composite system. The ZYE vacuum degassing machine generates extremely high shear rates and local pressure during the rotation process through optimized machine parameters. The strong shear force can break the surface tension barrier of the liquid metal, tearing it into countless micron or even nano-scale droplets. Once the fresh surfaces of these droplets contact trace oxygen in the air or dissolved oxygen in the silicone oil, they instantly form a solid gallium oxide (Ga₂O₃) film, encapsulating the droplet surface. Encapsulated by the silicone oil, the behavior of the liquid metal droplets changes. They disperse more readily into small droplets within the silicone oil, forming a "liquid metal emulsion."
（三）Adjustable Parameters Adapt To Different Mixing Needs
Different application scenarios require variations in the parameters of the liquid metal-silicone oil composite system, such as the dispersion particle size of the liquid metal, the viscosity of the mixed system, and the solid-liquid ratio, which need flexible adjustment. The ZYE planetary mixer pharmaceutical supports precise control of multiple parameters including revolution speed, rotation speed, mixing time, and vacuum level: By adjusting the speed ratio between revolution and rotation, the shear force and convective intensity can be modified. The equipped vacuum system can eliminate bubbles generated by high-speed rotation.
（四） High Efficiency And Energy Saving Ensure Production Continuity
Compared to traditional mixing equipment that requires prolonged high-speed stirring to achieve preliminary mixing, the ZYE paste mixer achieves deep mixing of liquid metal and silicone oil in a relatively short time due to its efficient force field transmission, significantly improving production efficiency. Simultaneously, the device features an optimized power transmission structure, resulting in lower energy consumption. Its independent vessel design minimizes material residue, facilitates cleaning, and meets the continuity and economic requirements of scaled production.
Currently, ZYE planetary vacuum mixer have achieved full-scenario coverage – processing capacity seamlessly connects from 2g small lab samples to 100kg scale production batches. The viscosity adaptation range comprehensively covers 0-2 million cps, perfectly meeting enterprise needs throughout the entire cycle from R&D and small-scale trials to pilot verification and batch production.
