Title: Production of carbonaceous powder for electroviscous fluid
Inventor: HARAOKA TAKUJI
IPC: C10N20/00
Filed: 1991-09-10
Abstract: PURPOSE:To obtain carbonaceous powder giving an electroviscous fluid having low electric current value in an electric field by carrying out the crushing and classification of an organic compound such as tar in a specific atmosphere. CONSTITUTION:An organic compound selected from coal tar, petroleum tar and resin is used as the raw material. When the material contains free carbon, it is removed by centrifugal separation, etc., at need. The material is heat- treated to proceed the carbonization until the ratio of the number of carbon atoms to that of hydrogen atoms (C/H ratio) reaches 2-3.5. The heat-treated material is crushed and classified in an atmosphere having an oxygen concentration of <=10wt.% and a water concentration of <=0.1wt.% and a fraction having an average particle diameter of 2-40mum is collected to obtain the objective carbonaceous powder for electroviscous fluid. An electroviscous fluid having excellent electroviscous effect and low electric current under the application of electric field can be produced by homogeneously dispersing the carbonaceous powder in an electrically insulating oily medium.

The beams 12 are reflected by the mirror 10 and are again passed through the molecular layer 1 and are again reflected by the mirror 9. The beams 10 repeat the reflections by as much as the rotation determined by the incident angle thetato the mirror 10, the length (l) of the mirrors 9 and 10 and the spacing (d) between the mirrors 9 and 10. The light quantity is detected by a photodetector 13. This light quantity and the light quantity of the light source 11 are compared to determine the light attenuation quantity. The film thickness of the molecular layer 1 is determined from the absorption coefft. of the molecules of the org. compd. The immersing and pulling up of a substrate 7 to be treated are repeated while the film thickness is monitored in such a manner, by which the thin film is grown to the prescribed thickness.
