Case Study: Quenched Glass Powder Slurry

Quenched glass powder slurry is a key functional material for high-performance composites, electronic packaging, coatings, and ceramics, used across aerospace, automotive, construction, and electronics. Particle size, dispersion uniformity, surface activity, and resin compatibility directly affect mechanical properties, appearance, reliability, and batch consistency, ultimately influencing market competitiveness.

Limitations of Conventional Processing

Quenched glass powder has high hardness and low surface energy, which in traditional processing often causes agglomeration, uneven dispersion, poor surface modification, and broad particle size distribution. These issues reduce interfacial bonding, lower mechanical strength, and increase cracking in finished composites.

Surface Coating Modification

1. Limited effectiveness: only 40–50% of particles are uniformly coated.
2. Uneven heating causes local agglomeration and poor dispersion stability.
3. Coatings easily detach, leading to poor batch consistency and defects such as delamination and cracking.
4. Not suitable for scale-up;defect rates increase by over 22%.
5. High additive consumption and environmental pressure.

Plasma Surface Treatment

1. Suitable only for small batches and thin layers; low scalability and efficiency.
2. Strongly affected by temperature and humidity; short-lived surface activity.
3. Risk of over-treatment, reducing compatibility with resin systems.
4. Difficult to meet large orders; longer lead times and higher inventory costs.

Mechanical Grinding & Dispersion

1. Coarse processing causes over-crushing and wider particle size distribution.
2. Requires multiple cycles with high energy consumption; agglomeration often remains.
3. Insufficient surface modification weakens bonding with resin matrices.
4. Large batch variability, increasing risk of complaints and recalls.

Solution : High Pressure Homogenization

Experimental Plan

We offer customized ultra-high-pressure homogenization solutions for quenched glass powder slurries. This purely physical high-pressure process generates strong shear, impact, and cavitation forces to break agglomerates, refine particles to the nanoscale, and achieve uniform surface modification. Adjustable pressure and cycles enable one-step dispersion and modification while preserving intrinsic material properties.

Processed at 260 MPa (1 cycle) and 300 MPa (19 cycles), with particle size, dispersion, and stability evaluated.

Experimental Conclusion

  • Particle Refinement: Reduced from ~3 μm to ~260 nm (DLS), achieving efficient micro-to-nano transition.
  • Improved Dispersion: Agglomerates eliminated; PDI stabilized at 0.07–0.1 with narrow distribution.
  • Enhanced Stability: Uniform, no sedimentation or wall adhesion; improved flowability.
  • Better Modification: More uniform coating and higher surface activity, improving resin compatibility.
  • Optimized Performance: Gentle physical process preserves structure, enhancing strength, stability, and yield of final composites.
