JINGKELIAN RJCS solvent resistance Tester coating solvent wiping resistance

Equipment introduction

Solvent Wipe Resistance Tester is a device used to measure the solvent wipe resistance of coatings. Use a wiping head with a certain speed and wiping pressure (absorbent cotton wetted with a solvent in contact with bread) to wipe back and forth on the surface of the sample. The number of wiping times can be directly read by the counter. According to the number of wiping times required for coating damage, the coating can be evaluated Excellent solvent wipe resistance. Implementation of the standard GB/T23989.

Instructions

1. Unscrew the fastening bolts on the sample fixtures at both ends, place the 75×200mm sample on the phenolic fixing plate, and then tighten the fastening bolts.

2.

The wiper head is placed on the slide arm.

3. Plug in the power supply, set the number with the counter, 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, and the machine starts to work. After reaching the predetermined number of times, the machine stops automatically, and the sample is removed 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 working.
