PURPOSE:To measure surface roughness and wettability at the same time by loading a discoid sample, and bringing one surface into contact with the surface of liquid, and rotating the sample and detecting torque as a funtion of the load. CONSTITUTION:The rotary measurement part consisting of the sample 7, sample holder 8, torque meter 9, output shaft 10, into shaft 11, and a motor 12 is balanced with the load 15, and while the sample 7 is brought into contact with the surface of the water 17 in a water tank 16, the measurement part is balanced again. The load 15 is adjusted to place a specific test load W on the rotary measurement part and the sample 7 is rotated by the motor 12 to read the fluid resistance between the sample 7 and water 17 on the torque meter 9 as torque T. The load W is varied and the measurement of torque W is repeated as the function of the W, measuring the surface roughness and wettability of the same 7 at the same time. |
