Thermostatic tape holding tack test machine
Designed and manufactured in accordance with GB 4851 (Test Method for Pressure Sensitivity of Pressure-Sensitive Adhesive Tapes) and Adhesive Adhesion Test Standards. It is suitable for pressure-sensitive adhesive tapes, stickers, plasters, hot melts and other products to carry out the adhesion test.
Hang the test plate with the adhesive sample vertically on the test stand, and suspend the weight of the specified weight at the lower end. Use a certain amount of displacement of the sample after a certain time, or the time when the sample completely detaches to characterize the adhesive test. The ability to resist pull-out. (as the picture shows)

1. After removing the 3 to 5 turns of the adhesive tape on the outer layer of the adhesive tape test paper, unwind the sample roll at a rate of about 300 mm / min (for sheet samples, remove the barrier layer at the same rate). At about 200 mm intervals, cut a sample with a width of 25 mm and a length of about 100 mm in the middle of the adhesive tape. Unless otherwise specified, the number of samples in each group is not less than three;
2. Wipe the test plate and the loading plate with a cleaning material moistened with a cleaning agent, and then dry them carefully with a clean gauze. Repeat this three times. Above, until the working surface of the board is cleaned by visual inspection. After cleaning, do not touch the working surface of the board with your hands or other objects;
3. At a temperature of 23 ° C ± 2 ° C and a relative humidity of 65% ± 5%, paste the sample parallel to the longitudinal direction of the board in the size specified in Figure 2 to the middle of the test board and the loading board next to it. Use a pressure roller to roll on the sample at a speed of about 300 mm / min. Note that during rolling, only the force generated by the mass of the pressing roller can be used to apply to the sample. The number of rolling times can be specified according to the specific product situation. If there is no regulation, the rolling times are three times;
4. After the sample is pasted on the board, it should be left for 20 min under the conditions of temperature 23 ℃ ± 2 ℃ and relative humidity 65% ± 5%. Then fix the test plate vertically on the test stand of the instrument, and gently connect the load plate and weight with pins.
5. Place the instrument horizontally, turn on the power switch, heating switch, and fan switch in sequence. Press the raised part on the timer to clear the time. The instrument automatically starts at the preset temperature until the temperature in the test chamber is constant to the set value;
6. After reaching the specified time, remove the heavy objects. Measure the downward displacement of the sample with a magnifying glass with indexing accuracy to 0.1 mm; or record the time when the sample falls off the test plate. If the time is greater than or equal to 1h, the unit is min, and if the time is less than 1h, the unit is s.
