5-3 FPIA Particle Size Measurement After Classification

Classification results of experimental particles using the wet classification device S-150W <<Under-sieve pass products>> Sample 1

- Particles that passed through the sieve are assumed to be "acceptable products." - To completely remove particles larger than 5 μm at the count level, a sieve with an average hole diameter in the upper 4 μm range, referred to as the "Super Micro Sieve," is installed in the classification device. The wet classification device S-150W is used to classify acrylic experimental particles. - The "acceptable products" that passed through the sieve were measured using the image analysis device FPIA-3000. Out of approximately 150,000 particles, none larger than 5 μm were detected. The cut line is estimated to be around 4.5 μm based on the maximum particle size. - The cut line refers to the maximum hole diameter of the sieve targeted during particle classification.
