Achieves dispersion, emulsification, pulverization, and exfoliation of fine particles.｜What is Star Burst?

Solves problems that occur when homogenizing particles

Processing or homogenizing of particles to nano level size can improve their efficacy. Homogenization of nanoparticles or ultrafine particles refer to the process of reducing the average diameter of a solid material's particles.

For homogenization:
Dispersion loosens aggregated particles into primary particles, Emulsification reduces droplet size in a liquid, Pulverization refers to crushing primary particles, and Exfoliation peels layered substances while maintaining the aspect ratio - cleavage, etc.

For homogenization

However, when milling with grinding media like a beads milling,
there can be contamination problems (impurities).

Star Burst's water-jet method solves these problems.

What is dispersion, emulsification, pulverization, and exfoliation by the water jet method?

What is a water jet?

High pressure water sprayed from a thin nozzle that exceeds the speed of sound.*
* Injection speed of 245MPa: Mach 2 (700m / s)

Powerful enough to cut iron, ideal for material processing.

Star Burst utilizes the power of water jet technology.

The raw material (slurry or emulsion) is jetted from the nozzle at high speed to make a water jet.

The strong shearing force applied during injection and the energy generated by collisions between raw materials atomize the raw materials to the nano level.

Difference from other processing methods

Characteristics of dispersion, emulsification, crushing, and cleavage by water jet method

Minimum Contamination

Star Burst does not use any grinding media and provides products with the minimum amount of contamination.

Minimum Contamination

Homogenized Particle Size

Uniform particle with narrow particle size distribution can be achieved by controlling the injection speed of raw material.

Homogenazed Particle Size

High Pulverizing Capability

Effective nano-level pulverization and dispersion can be achieved in a short duration of time.

High Pulverizing Capability

Excellent Scale-up

Processing results achieved during research and development (R&D) are highly reproducible with our larger production-scale machines, making the transition to full scale production smooth and easy.

Excellent Scale-up
