Why Nanomaterial Dispersion Is Exceptionally Challenging

Nanoparticles possess extremely high surface energy, causing them to re-agglomerate into tight clusters. Traditional mechanical dispersion techniques struggle to provide uniform results..
Severe Nanoparticle Agglomeration

Strong van der Waals forces cause nanoparticles (like CNTs and Graphene) to form dense clusters. Standard low-shear agitators cannot provide sufficient localized energy to break these bonds.

High Resistance to Flow
Structural Damage from Over-Shearing

Traditional high-speed bead mills or stator-rotor homogenizers often apply excessive mechanical impact, snapping high-aspect-ratio nanomaterials (e.g., cutting CNT length) and degrading electrical conductivity.

Dead Zones & Incomplete Dispersion
Metal Contamination & Blade Wear

Abrasive nano-ceramics (Alumina, Zirconia, Silica) rapidly erode metal blades and bead-mill grinding media, introducing heavy metal impurities into high-purity battery or semiconductor pastes.

Wall Adhesion & Poor Heat Transfer
Entrapped Air & Viscosity Instability

High-surface-area powders entrap vast amounts of micro-air pockets during charging, causing batch viscosity fluctuations, settling, and premature drying.

Entrapped Micro-Bubbles & Voids

Measurable Quality Upgrades in Nanomaterial Slurries

Achieving true sub-micron de-agglomeration directly boosts the electrical, thermal, and mechanical performance of the final compound.

How Planetary Centrifugal Technology Achieves Sub-Micron Homogenization

By rotating the container around two axes simultaneously, our technology creates intense internal fluid movement and high shear forces—without any blades entering the fluid.

Key Technical Advantages:

Ultra-High G-Force Shear Acceleration Simultaneous revolution and rotation subject the slurry to immense centrifugal g-forces, generating high velocity gradients that tear nanoparticle agglomerates apart.
Preserved Nanomaterial Integrity Non-contact shear distributes kinetic energy evenly through liquid convection, de-agglomerating powders without breaking CNT aspect ratios or damaging graphene flakes.
00% Non-Contact & Zero Contamination Mixing occurs entirely inside disposable or custom containers. No blades, no grinding beads, and zero risk of cross-contamination or metal wear.
1Simultaneous High-Vacuum Degassing Gas adsorbed on nanoparticle surfaces is stripped away continuously under high vacuum, preventing re-agglomeration and ensuring void-free slurries.

    Frequently Asked Questions About Vacuum Degassing

    What vacuum level can Berlon equipment achieve?

    Our built-in high-vacuum system achieves ultimate vacuum levels down to sub-atmospheric pressure (-0.098 MPa / -98 kPa or higher), ensuring sub-micron level gas removal.

    Can planetary vacuum mixers handle volatile or flammable solvents?

    Yes. For hazardous formulations containing volatile solvents (e.g., NMP, acetone, ethanol), we offer custom Explosion-Proof (C1D1 / Zone 1) configurations with positive pressure purging systems.

    How long does a typical vacuum degassing cycle take?

    While traditional static ovens take up to 2 hours, our planetary centrifugal vacuum technology achieves complete mixing and micro-degassing in just 2 to 5 minutes.

    Can we test our material before committing to a purchase?

    Absolutely. We offer free material trial runs at our application facility. Send us your raw materials, and we will return the degassed samples along with a comprehensive process report.
