Why Do We Need Thermal Conductive Slurry Defoaming Machine
Power Device Heat DissipationThermal grease or gel is applied to fill thermal interfaces of IGBT and power modules. Air voids increase thermal resistance, resulting in poor chip heat dissipation, temperature rise and shortened service life. | High Filler AgglomerationHigh thermal conductive fillers such as aluminum oxide and boron nitride are prone to agglomeration. Air trapped during stirring breaks thermal conduction paths, degrading thermal performance and causing batch fluctuations. | LED & Lithium BatteryLED heat dissipation and lithium battery thermal management demand high thermal consistency. Air voids trigger local hot spots and impair reliability and safety. |
✨ Traditional Dilemma: Manual stirring of high-filler pastes causes both air entrapment and filler agglomeration, leading to unstable thermal resistance. Synchronous vacuum defoaming and dispersion is required.
Why Choose SIENOX Thermal Conductive Slurry Defoaming Solution
Bubble Removal for Lower Thermal ResistanceRemoving air voids enables tighter contact between fillers, forms continuous thermal conduction paths, reduces interfacial thermal resistance and delivers more reliable heat dissipation. | Break Filler AgglomeratesRotational shear breaks up agglomerates of aluminum oxide and boron nitride for even filler distribution and stable thermal conductivity consistency. | Non-contact & CleanNo contamination to thermal conductive systems with reproducible formulations. Smooth scale-up from lab samples to mass batches. |

How does the stirring and defoaming machine work?
The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,
Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.
-
What is the function of a defoaming machine?
A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.

Precautions for Use
| Notes | Operation Instructions |
| Loading & Rotation Speed | High-filler materials tend to sink. Match cup loading volume with rotation speed to ensure uniform filler dispersion. |
| Heating for Viscosity Reduction | High-viscosity thermal conductive pastes can be properly heated to lower viscosity before defoaming for higher efficiency. |
| Slow Pressure Relief | Release pressure slowly after defoaming to prevent re-foaming of paste. |
| Contamination Prevention | Avoid cross-contamination between different filler systems and keep tools and containers clean. |
