Why Must Microbubbles in Materials Be Eliminated?

Residual nanoscale micro‑bubbles within materials directly affect product yield and performance stability.

Polymer Composite Material Industry

Micro‑bubbles trapped inside polymer raw materials such as epoxy resin and silicone will form voids and micro‑cracks after curing, reducing the tensile strength and sealing performance of finished parts. Bubbles degrade light transmittance and surface uniformity, raise defective rates for injection‑molded / cast products and increase raw‑material waste costs.

Cosmetic Paste Industry

Bubbles inside makeup and skincare pastes cause uneven spreading and patchy color appearance. Compressed bubbles during filling lead to filling‑volume deviation, which jeopardizes metering compliance. Internal voids accelerate raw‑material oxidation and shorten the shelf‑life of finished products.

Ceramic Conductive Slurry Industry

Bubbles trapped in ceramic slurries result in pinholes and porosity defects on sintered bodies, causing fluctuations in conductive and insulating performance. Bubbles bring inconsistent coating thickness and scattered resistance parameters of components, making it difficult to unify parameter control for mass‑produced products.

✨ Challenges of conventional defoaming: Ordinary planetary mixer‑defoamers rely on centrifugal force to remove bubbles, with limited performance on nanoscale micro‑bubbles trapped in high‑viscosity materials. Static defoaming is time‑consuming and incomplete. Vacuum mixing‑defoaming applies ‑98 kPa negative‑pressure vacuum during planetary agitation, lowering the pressure difference inside and outside bubbles to enable micro‑bubbles to expand and escape. It delivers deep‑layer defoaming results unachievable by conventional mixing methods.

Why Choose SIE‑MIX2000

Engineered for Vacuum Defoaming in Small‑Batch Production

Customizable Capacity Upon Request

Standard 2L dual‑station base model, capacity adjustable within 0‑30L range. Compatible with large‑volume single‑bucket materials and multi‑batch continuous mass‑production conditions. Supports large‑size mixing vessels and custom tooling fixtures, covering requirements for small‑batch pilot tests and scaled‑up production lines. Suitable for multi‑viscosity pastes and liquid raw materials.

Coordinated Revolution & Rotation

Dual‑driven planetary structure. Revolution generates centrifugal force to spread materials, while vessel rotation creates 360° fluid shear to reduce powder agglomeration and colloid delamination. Speed range adapts to adhesives, silver pastes, ceramic materials and other substances for broader mixing coverage and less local inhomogeneity.

Intelligent Industrial Control

Equipped with large‑size touch‑screen for storing multi‑segment running recipes. Optional MES industrial data interface to fully record full‑process data including speed, vacuum level, temperature control and duration. Built‑in audio‑visual alarm, multi‑safety interlocks and overload power‑off protection for standardized continuous factory production.

✨ When vacuum defoaming is required and production volume reaches the 2000 mL level, the SIE‑MIX2000 is the small‑batch pilot‑scale option within the planetary vacuum defoaming mixer series.

Working Principle

Adopts synergistic process combining planetary revolution, vessel rotation and closed high‑vacuum environment.

Planetary Revolution: The large plate holding material cups rotates at high‑speed around the main shaft to generate centrifugal force. Materials are spread evenly against vessel walls, which breaks powder agglomeration and mitigates colloid delamination. 

Vessel Rotation: Material cups perform synchronous counter‑rotation, generating 360° fluid turbulence inside vessels for full‑range homogeneous mixing. No built‑in mixing paddles contact materials, lowering the risk of contamination by metal debris. 

Closed‑Chamber Vacuum Defoaming: Negative pressure down to ‑98 kPa is pulled inside the sealed chamber. Expanded pressure difference between inside and outside materials makes micro‑ and nanoscale bubbles expand, rise and evacuate from the chamber. Mixing and defoaming are accomplished in one single process. It delivers better mixing uniformity and bubble removal performance than conventional open mixing equipment.

  • 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.
