[Case] Q. Regarding the particle size measurement method of Repcomica [Question Collection]
I will answer the questions that have been asked so far. Please use this to help resolve your concerns. Feel free to download the materials as well. ◎
Repcomica, known for its high aspect ratio, cannot provide all details, but we measure the average particle size using the method described below and calculate the aspect ratio by dividing the average particle size by the average thickness. If you would like to know more about the detailed method for calculating the aspect ratio, please feel free to contact us. Q. Particle Size Measurement Method A. We measure using laser methods and dry sieving methods. S Grade (Muscovite) S-150H, S-200HG M Grade (White Mica) M-60, M-200 The above are measured using the dry sieving method. S Grade (Muscovite) S-325, S-400, S-XF M Grade (White Mica) M-325, M-400, M-XF The above are measured using the laser method. Please feel free to download the detailed content. ↓↓↓↓↓↓↓
