ZL-5072B Rotating Friction Tester

This instrument uses a box design, and the upper part of the instrument can be rotated backwards. When in use, turn the upper part of the instrument back from the normal state to make the vertical rod in a horizontal position, and place the sample on the bottom of the instrument stably, and then put the upper part of the instrument back to its original position, so that the lower end of the vertical rod covered with the test white cotton cloth Touch the part of the sample that needs to be tested, turn the handle to drive the vertical rod to rotate, so that the white cotton cloth and the sample rub against each other. A weight is installed at the upper end of the vertical rod, and a pressure of 1143g is applied to the sample. Observe the degree of color sticking that occurs when the sample rubs against the white cotton cloth under this pressure. This instrument can be used for wet friction and dry friction.
