Wipe the test plate and loading plate with cleaning agent, and then dry them carefully with clean gauze. Repeat three times until the working surface of the plate is clean through visual inspection. After cleaning, do not touch the working surface of the plate with hands or other objects.

Under the condition of 23 ℃± 2 ℃ and 65% ± 5% relative humidity, paste the specimen parallel to the longitudinal direction of the plate in the middle of the adjacent test plate and loading plate according to the size specified in Figure 2. Roll the specimen with a press roll at a speed of about 300 mm / min. It should be noted that when rolling, the roller of specified quality should be used to roll back and forth according to the times specified in the standard. Only need to push the roller gently instead of using external pressure so that the roller can roll on the sample. The rolling times can be specified according to the specific product conditions. If there is no regulation, the rolling shall be repeated three times.

After the specimen is pasted on the plate, it shall be placed for 20 min under the conditions of 23 ℃ ± 2 ℃ and 65% ± 5% relative humidity. Then fix the test plate vertically on the test stand, and connect the loading plate and the weight lightly with the pin. The whole test stand is placed in the test chamber which has been adjusted to the required test environment. Record the test start time.

When the time is up, remove the heavy objects. The sliding displacement of the sample is measured with a magnifying glass with graduation, and the accuracy is 0.1mm; or record the time when the specimen falls off the test plate. If the time is more than or equal to 1h, the unit used is min, and if the time is less than 1h, the unit used is s.

The test results are expressed as the arithmetic mean of displacement or falling off time of a group of samples.

Peeling force test

1. Working principle: in the Peeling force test, the standard width tape is used to adhere to a specific steel plate, and then the tape is torn from the steel plate by a manipulator, and the stable force of the manipulator reflects the peeling force.

2. Testing tools: peel strength tester, manual rolling roller, and steel plate.

3.Operation method: cut the tape into a standard test piece with a width of 25.4mm and a length of 300mm. Adhere the cut tape to the standard 304# mirror smooth steel plate. After pasting, use standard 2kg rolling roller to press back and forth three times. After pressing, pay attention that there should be no bubbles in the tape. After pressing, put it still for a few minutes so that the best effect of the adhesive tape can be achieved. Peel off one end and fix the test piece vertically on the fixture of tensile testing machine. After these, start the test.
