Introducing a case study on the dispersibility of carbon black mixed with PVDF in NMP.
We present a case study conducted by Majerika Japan Co., Ltd., measuring the relaxation times of carbon black immediately after dispersion and one day later. Carbon black was added to a dispersion medium mixed with NMP and PVDF to achieve a concentration of 30 wt%. The relaxation times of four types of dispersions with different stirring conditions were measured using the "MagnoMeter SED." As a result, even with high concentration and black samples, we were able to quantify and compare the dispersibility without dilution. 【Case Overview】 ■ Experiment - Carbon black was added to a dispersion medium mixed with NMP and PVDF to achieve a concentration of 30 wt%. - Dispersion was carried out using a public rotary stirring and degassing device, the Kakuhunter SK-400TR. - The relaxation times of four types of dispersions with different stirring conditions were measured. ■ Discussion - Even with high concentration and black samples, we were able to quantify and compare the dispersibility without dilution. *For more details, please refer to the PDF document or feel free to contact us.
