Application of Laser Particle Size Analyzer in Silica

Testing the particle size distribution of silica helps to ensure its application effect, process feasibility and final product quality stability.

1. Determine core performance: Particle size and distribution directly affect key properties of silica such as specific surface area, bulk density, dispersibility, optical properties (such as transparency and matte effect) and enhancement effect.

2. Impact on process and stability: Uniform particle size distribution helps optimize production processes (such as extrusion, coating, tableting) and ensure product batch consistency.

3. Ensure the quality of the final product:

Silica sol: Particle size determines its stability, viscosity and performance in polishing, coating and casting.

Catalyst carrier: Particle size distribution affects the uniformity of active component loading and reaction efficiency.

4. Control production costs: Accurate particle size detection is the basis for achieving raw material quality control, reducing defective rates, and reducing energy consumption and raw material waste.

Laser particle size analyzer is the cornerstone of particle size quality control in the silica industry, from raw material purification to high-end material manufacturing.

1. Wide dynamic range: The combination of Mie scattering theory and Fraunhofer diffraction enables the measurement range to cover the nanometer level (0.01μm) to the millimeter level (1200μm).

2. High resolution and precision: Multi-wavelength laser source and reverse Fourier optical system achieve sub-micron resolution and accurately analyze multi-peak distribution.

3. Non-invasive testing: Dry dispersion (dry-turbulence dispersion and normal shock wave shear technique) and wet dispersion (ultrasonic, string, circulation) avoid sample damage and ensure the cleanliness of high-purity electronic materials.

Therefore, it is very important to detect the particle size distribution of silica, which is one of the functions of the laser particle size analyzer. This time, Winner 2308B is recommended to test the particle size distribution of silica powder for customers.
