Title: Polishing agent
Inventor: DOBASHI YUTAKA
IPC: B24B37/00
Filed: 1985-05-09
Abstract: PURPOSE:To improve sharpness of abrasive grains while to prevent cohesion and to prevent dispersion under grinding by adding hydrophilic fiber material into polishing agent employing aqueous dispersion medium. CONSTITUTION:Polishing grains such as artificial diamond powder is employed where the average grain size is selected with correspondence to the purpose. While micro fibril cellulose is employed as hydrophilic fiber material. The diameter is shorter than several (mum) and suitable for catching the abrasive grains in dispersed condition. Since cellulose is sufficiently long when compared with the diameter of fiber, dispersed condition can be maintained in dispersion medium. Consequently, the abrasive grains can be caught even upon application of high shearing force thus to prevent dispersion. Water, alcohol or their compound is employed as aqueous dispersion medium. Consequently sharpness of abrasive grains is improved.
