Coating solvent resistance tester

RJCSCoating solvent resistance testerOperation Instructions:

1. Unscrew the fastening bolts on both ends of the sample fixture, place the 75 × 200mm sample under the rubber fixing plate, and then tighten the fastening bolts.

2. Take an appropriate amount of degreasing cotton and wrap it around the contact surface of the wiping head. Install the clamp, tighten the fixing screw, and then take an appropriate amount of degreasing cotton and place it in the inner cavity of the wiping head. Drop an appropriate amount of solvent into the wiping head until the solvent seeps out, and then place the wiping head on the sliding arm.

3. Plug in the power, use a counter to count, and select the number of times you want to wipe; Rotate the speed control knob and select the desired wiping speed (recommended 60 times/minute, i.e. the speed control knob points to MAX).

4. Turn on the power switch of the speed controller, and the machine will start working. After reaching the predetermined number of times, the machine will automatically stop. Remove 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 again to continue working.

6. After the machine automatically stops, simply press the "reset" button on the counter to restart the machine.

Notes:

1. It is strictly prohibited to turn on the machine without the sample and degreased cotton installed.

2. If the degreased cotton falls off, stop the machine as soon as possible.

RJCSCoating solvent resistance testerScope of application:

This instrument is referencedforeign countriesBased on the relevant standards and the actual situation in China, our company has designed and produced the RJCS type coating solvent wiping resistance tester.

The coating solvent resistance test method is a method of evaluating whether the cross-linking degree of the coating reaches the solvent resistance level by wiping the coating several times with appropriate solvent impregnated fibers or impregnated degreasing cotton.

This instrument is suitable for coatings that undergo chemical changes during the curing process of epoxy resin, ethylene resin, polyester, alkyd resin, and ethyl carbamate, such as hot-melt fluororesin coatings, colored steel plates and strips, aluminum-plastic composite panel coatings, etc.

Due to different coating types and expected uses, the solvent resistance level of their coatings also varies. For water-based coatings or coatings that react with water, the number of times they reach a specific solvent resistance level will be affected by temperature, film thickness, air flow, and humidity.
