Why Must Microbubbles in Materials Be Eliminated?
Residual microbubbles in materials directly affect the yield and performance stability of end‑products.
Electronics IndustryBubbles in potting compounds create cavities and voids after electronic component encapsulation, impairing heat dissipation and insulation reliability. Bubbles in conductive silver paste cause circuit breakpoints and resistance fluctuation, while bubbles in circuit‑board bonding adhesives trigger interface defects and reduce product yield. Medium‑ and high‑viscosity adhesives tend to entrain air during conventional mixing; bubbles escape slowly, undermining the consistency of encapsulation quality. | Medical Device IndustryBubbles in medical adhesives weaken bonding strength and biocompatibility. Bubbles within encapsulants for catheters and sensors lead to seal failure and signal interference, and bubbles in carriers for in‑vitro diagnostic reagents compromise detection accuracy. Medical devices demand high material purity; residual bubbles may cause batch‑to‑batch performance variation and raise quality‑related risks. | Aerospace & Defense IndustryBubbles in composite matrix resins reduce interlaminar shear strength and fatigue resistance. Bubbles in structural adhesives induce stress concentration at bonding interfaces and compromise long‑term reliability, whereas bubbles in radar‑absorbing coatings alter electromagnetic performance parameters. The aerospace sector has low tolerance for internal material defects; residual micro‑bubbles may trigger structural‑part failure under extreme operating conditions. |
✨ Limitations of traditional defoaming methods: Manual or impeller stirring entrains more air bubbles; static defoaming is time‑consuming and ineffective for high‑viscosity materials; conventional vacuum treatment can only remove surface bubbles rather than internal microbubbles. The planetary mixer‑defoamer separates bubbles via centrifugal force while mixing. Combined with vacuum negative pressure for deep defoaming, it finishes mixing and defoaming in one step.
Why Choose MIX650
Three Core Advantages to Cover Full‑Process Requirements of Medium‑Capacity Vacuum Defoaming
Built‑in Maintenance‑Free Vacuum for Clean DefoamingEquipped with a built‑in vacuum unit, the MIX650 requires no regular pump‑oil replacement for maintenance‑free operation with zero environmental pollution, ideal for clean‑room environments. Vacuum level is adjustable from ‑98 kPa to 0 kPa, allowing flexible parameter setup based on material viscosity and bubble characteristics. The integrated design eliminates external vacuum pump piping and extra space occupation. Featuring high integration, the unit starts vacuum defoaming right after power‑on to reduce production‑line change‑over time. | 500 mL Medium‑Capacity with Wide‑Range Speed Control500 mL dual‑cup configuration fits pilot‑scale R&D and continuous production‑line sampling. Synchronized dual‑cup operation improves batch efficiency. Wide‑range speed adjustment from 0‑2000 rpm accommodates low‑, medium‑ and high‑viscosity materials. Low‑speed settings enable gentle mixing and defoaming for high‑viscosity adhesives, while high‑speed modes deliver fast dispersion for low‑viscosity coating liquids. Synchronized dual‑driven revolution‑rotation completes mixing and defoaming in one step within approximately 1 minute. | Flexible Multi‑Segment Program Process ConfigurationThe microcomputer control system supports storage of up to 100 programs. Each program contains multiple segments with independently configurable time and speed for multi‑stage process parameter setup. User permission management and fault‑code display suit shared‑equipment scenarios with multiple operators. Program‑driven operation minimizes manual adjustment errors and guarantees consistent performance across batches. |
✨ The MIX650 integrates three core capabilities: built‑in vacuum for maintenance‑free operation, medium‑capacity dual‑cup design up to 500 mL with wide‑range speed adjustment, and flexible multi‑segment programming. It is suitable for pilot‑scale R&D and production line sampling of materials for electronic packaging, medical device bonding, aerospace composite materials and more.
Working Principle
Synchronized operation of dual‑driven revolution and rotation enables one‑step completion of mixing and defoaming.
Step 1: Centrifugal Force from Revolution The rotating revolution plate drives the container and materials to generate strong centrifugal force, triggering full convection of materials for macro mixing. Meanwhile, centrifugal force pushes low-density bubbles toward the rotation axis, gathering and releasing large bubbles. Step 2: Shear Force from Rotation The container rotates around its own axis to produce directional shear force, breaking up agglomerated particles for micro dispersion. High speed up to 3000rpm creates powerful shear for efficient full-volume mixing, thinning bubble membranes and accelerating bubble rupture. Step 3: Vacuum Negative Pressure Boosts Defoaming While revolution and rotation proceed, the vacuum system reduces chamber pressure to -98kPa. Under low pressure, pressure difference inside and outside bubbles expands nano-sized microbubbles and speeds up their floating and release. Vacuum defoaming compensates the limitation of centrifugal force on tiny bubbles, achieving full-range defoaming from large bubbles down to nanoscale bubbles. Revolution, rotation and vacuum work simultaneously. Materials complete the full process of "Mixing → Dispersion → Deep Defoaming" inside the sealed container. 3000rpm high speed combined with -98kPa vacuum balances mixing efficiency and defoaming depth. |  |
