CHINA ASR-5604-10B thermostatic tape retention testing machine

Introduction

Designed and manufactured in accordance with GB 4851 (Test method for stickiness of pressure-sensitive adhesive tapes) and test method for stickiness of plasters, it is suitable for stickiness tests of pressure-sensitive adhesive tapes, self-adhesives, plasters, hot melts and other products.

Test Principle

Hang the test plate with the adhesive sample on the test frame vertically, hang the weight of the specified weight at the lower end, and use the displacement of the sample after a certain period of time, or the time when the sample is completely detached, to characterize the adhesive test. The same ability to resist pull-off. (as the picture shows)

design standards

• GB 4851 Pressure-sensitive adhesive tape tack test method

• JIS Z0237 Test methods for pressure-sensitive adhesive tapes and pressure-sensitive adhesive sheets 　　

• ASTM D3654 Test Method for Shear Adhesion of Pressure Sensitive Tapes

operation method

1. After removing 3-5 rounds of adhesive tape on the outermost layer of the adhesive tape test paper, untie the sample roll at a speed of about 300 mm/min (for sheet samples, remove the isolation layer at the same speed), Every 200 mm or so, 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 shall not be less than three;

2. Wipe the test plate and loading plate with cleaning agent, then dry them carefully with clean gauze, and repeat this process for three times. above, until the working surface of the plate is clean by visual inspection. After cleaning, do not touch the working surface of the plate with hands or other objects;

3. Under the conditions of temperature 23°C±2°C and Relative Humidity 65%±5%, according to the size specified in Figure 2, paste the sample parallel to the longitudinal direction of the plate on the middle of the adjacent test plate and loading plate. Roll on the sample with a pressure roller at a speed of about 300 mm/min. Note that when rolling, only the force generated by the mass of the roller can be applied to the sample. The number of times of rolling can be specified according to the specific product conditions. If there is no regulation, it should be rolled back and forth three times;

4. After the sample is pasted on the board, it should be placed at a temperature of 23°C ± 2°C and a Relative Humidity of 65% ± 5% for 20 minutes. Then fix the test board vertically on the test frame of the instrument, and gently connect the loading board and the weight with pins.

5. Place the instrument horizontally, turn on the power switch, heating switch, and fan switch in sequence, and press the raised part on the timer to reset the time. The instrument automatically starts up according to the preset temperature until the temperature in the Test Chamber is constant to the set value;　

6. After the specified time is reached, remove the heavy objects. Use a graduated magnifying glass to measure the displacement of the sample sliding down, accurate to 0.1mm; 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 it is less than 1h, the unit is s.
