Application of Laser Particle Size Analyzer in Pearl Powder

The unique optical effects (pearl luster, angular color) and wide applications (cosmetics, automotive paint, plastics, inks) of pearl powder are highly dependent on precise particle size control. Laser particle size analyzer, with its efficient and accurate measurement capabilities, has become a key technology to ensure the quality and innovation of pearl powder.

1. Core influence of particle size on application

Customization of optical effects: D50 value determines the main gloss (fine powder: soft light and high hiding; coarse powder: strong flash and low hiding). Span value (distribution width) affects batch stability and color purity.

Processing and performance: Particle size affects dispersibility (anti-agglomeration), rheology (spraying/printing suitability), sedimentation stability and surface smoothness.

2. Core advantages of laser particle size analyzer

Fast, accurate and objective: Replaces the time-consuming and subjective microscopy method. D10/D50/D90/Span values are measured in a few minutes with good data repeatability.

Wide range and high compatibility: Covering nanometers to hundreds of microns. Suitable for both wet method (simulating the actual system) and dry method.

Flake structure optimization: Special optical model reduces the measurement error of flake particles.

3. Key application scenarios

R&D design: Establish a database and model of particle size parameters (D50, Span) and optical effects (gloss type, glitter intensity, angular heterochromaticity, hiding power). Reverse development of customized products (such as strong glitter of car paint and delicate light of makeup).

Production quality control: Real-time monitoring of grinding and grading process, optimization of parameters to ensure narrow distribution (such as Span≤1.2). 100% batch detection, eliminate color difference/gloss fluctuation, meet strict standards such as ISO.

Problem tracing: Quickly diagnose whether terminal problems (color difference, sedimentation, spraying defects) are caused by abnormal particle size (agglomeration, distribution out of control).

Conclusion: Laser particle size analyzer is the quality cornerstone and innovation engine of pearl powder industry. It ensures the consistency of visual effects from lipstick mercerization to automotive metallic paint by accurately quantifying particle size parameters, drives process optimization and product upgrade, and provides irreplaceable technical support for the high-end and compliance development of the industry. This time, Winner 2018 is recommended to test the particle size distribution of pearl powder for customers..
