1. Purpose:
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 the 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.
2. Main parameters:
1. Wiping stroke: 120±5mm
2. Wiping frequency: 0~60 times/min
3. Load: 1000±10 grams
4. Wiping head contact surface diameter: 14±0.5mm
5. Wiping pressure on the test board: 0.06Mpa
6. Test plate size: 75×200mm
7. Power supply: 220V 50Hz
8. Dimensions: 260×260×340 (length×width×height)
9. Weight: about 20kg
3. Instructions for use:
1. Unscrew the fastening bolts on the sample fixtures at both ends, place the 75×200mm sample under the rubber fixing plate, and then tighten the fastening bolts.
2. Take an appropriate amount of absorbent cotton and wrap it on the contact surface of the wiping head, install the hoop, tighten the fixing screws, then take an appropriate amount of absorbent cotton, put it into the inner cavity of the wiping head, and drop an appropriate amount of solvent until the wiping head has solvent oozing out. 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 required 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.
6. After the machine stops automatically, just press the "Reset" button on the counter, and the machine can run again.
4. Matters needing attention:
1. It is strictly forbidden to start the machine when the sample and absorbent cotton are not installed.
2. If the absorbent cotton falls off, stop the machine as soon as possible.
