Overview
The 180 ° Peel strength tester is a LD-BL-A (180 °/200kg) model product under the JINGHUAYIQI brand, which is professionally used for tensile testing and tensile strength testing of plastics, non-woven fabrics, leather, cloth zippers and other materials. By configuring different fixtures, it can be extended to paint, Plastic film, composite film, soft Encasement material, Adhesive, adhesive tape, sticker, rubber, paper and other materials tensile test, tensile strength and elongation, breaking force and elongation, right angle tear, heat sealing strength, Tear strength, 180 ° Peel Strength (including T type), 90 ° disbonding, anti-puncture test and other items testing.

8. Flexible re-test: manual maximum speed return or automatic return to the initial position
9. Customized tooling fixtures: customized according to user product sample requirements
Principle
The testing machine drives the test bench to carry out tensile motion through stepper motor and stepper drive Control system. High Accuracy Sensor is used to collect force value data, and the free end of the sample is folded 180 degrees and peeled off from the test plate, so that the disbonding surface is consistent with the force line of the testing machine. Continuous disbonding at the set disbonding speed, the automatic recorder plots the disbonding Linear dispersion, and calculates various mechanical properties through software analysis.
Applications
Plastic, Non-woven, Leather, Cloth Zipper, Paint, Plastic film, Composite film, Soft Encasement material, Adhesive, Adhesive tape, sticker, Rubber, paper
Standards
Adhesive tape disbonding test standard, ASTM D3330
Steps
1. Fold the free end of the sample 180 degrees and peel off the gluing surface 25mm from the test plate
2. Clamp the free end of the sample and the test plate on the upper and lower grippers respectively to ensure that the disbonding surface is consistent with the test machine line
3. Testing machine at 300mm/min +/- 10mm disbonding speed continuous disbonding
4. Linear dispersion for disbonding
5. Calculate the test results according to the distance between 20-80mm after peeling
6. Within the range of disbonding values, read a number every 20mm, and read at least 4 numbers to average
7. After the test is completed, different interval results and point analysis can be calculated
8. The system can distinguish the MAX Maximum, MIN Minimum and Average in the sample
9. With A4 paper size printing report and a variety of Linear dispersion analysis functions
Notice
• Ensure that the specimen is firmly held to avoid slippage
• The disbonding surface must be consistent with the test force line
• The disbonding speed should be controlled within the range of 300mm/min +/- 10mm
• The value calculation should be carried out within a distance of 20-80mm after peeling
• Read at least 4 values to average to ensure accuracy
• Regularly check equipment accuracy and Sensor status
• Safety protection device is functioning properly before operation
• Select the appropriate fixture and test parameters according to the characteristics of the sample
