[Measurement Example] Quantifying Surface Treatment

I will introduce a case regarding the wettability of alumina surface treatment presence or absence.

We would like to introduce a case study by Majelica Japan Co., Ltd. that compares the wettability using powders with significantly different interfacial properties. Water droplets were dropped on the powders before and after surface treatment to compare their wettability. Additionally, the relaxation times were measured when each was dispersed in distilled water and hexane. It was suggested that the wettability worsened in distilled water due to a decrease in Rsp from surface treatment, while the wettability improved in hexane due to an increase in Rsp from surface treatment. [Case Summary] ■ Experiment - Dropped water droplets on powders before and after surface treatment - Measured relaxation times when dispersed in distilled water and hexane ■ Results - Distilled Water: Suggested that wettability worsened due to a decrease in Rsp - Hexane: Suggested that wettability improved due to an increase in Rsp *For more details, please refer to the PDF document or feel free to contact us.
