HuiNuo RJCS coating Solvent Rub Resistance Tester

Introduction to the device

The solvent resistance wipe meter is a device used to determine the solvent wipe resistance of coatings, and the standard GB/T 23989 is implemented. A wiping head with a certain speed and wiping pressure (absorbent cotton wetted with solvent in contact with bread) is used to reciprocate on the surface of the specimen, and the number of wipes can be directly read by the counter, and the solvent resistance of the coating can be evaluated according to the number of wipes required for the coating to break.

Instructions

1. Unscrew the set bolts on the specimen grips at both ends, place the 75×200mm specimen under the fixing plate, and then tighten the set bolts.

2. Take an appropriate amount of absorbent cotton and wrap it on the contact surface of the wiping head, install the hoop piece, tighten the fixing screw, then take an appropriate amount of absorbent cotton, put it into the inner cavity of the wiping head, drip in an appropriate amount of solvent until the wiping head has solvent seepage, and then place the wiping head on the sliding arm.

3. Plug in the power supply, set the number with the setter, and select the number of times you want to wipe; Turn the speed control knob to select the desired wiping speed (60 times/min is recommended, that is, the speed control knob points to MAX).

4. Turn on the power switch of the governor, the machine starts to work, and after reaching the predetermined number of times, the machine will automatically stop and take off the sample for observation.

5. If you want to stop the machine during operation, you can directly turn off the power switch of the governor, and then turn on the power switch of the governor if you want to continue to work.

6. After the machine stops automatically, you only need to press the "Clear" button on the number setter, and the machine can run again.
