Overview
180 ° Peel strength tester is a professional testing equipment with model LD-BL-A (180 °/50kg) under the JINGHUAYIQI brand, which is mainly used for tensile testing and tensile strength testing of plastic, non-woven fabrics, leather, cloth zippers and other products. 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.
Features
1. Wide range of capacity options, available from 0 to 50kg and a variety of specifications (e.g. 2kg, 5kg, 10kg, 20kg, 30kg, 50kg, 100kg, 200kg).
2. Accuracy grade is high, reaching 0.5 level, force Measurement range 0.02/100 -100%, test force resolution maximum load 250,000 yards, inside and outside are not divided and the whole process resolution remains unchanged.
3. Control system adopts stepper motor and stepper driver, test bench lifting device supports computer digital control and manual pointing control.
4. The re-test function is flexible, and the manual can return to the initial position at the highest speed, and the automatic can return automatically after the test.
5. The fixture can be customized according to the user's product sample requirements, with strong adaptability.
6. With A4 paper size printing report and a variety of Linear dispersion analysis functions, it can distinguish the MAX Maximum, MIN Minimum, average value in the sample, and calculate different interval results and point analysis.
Principle
The testing machine makes sure that the disbonding surface is consistent with the force line of the testing machine by folding the free end of the sample in half 180 degrees and peeling it off the test plate, gluing the surface 25mm, and then clamping the free end of the sample and the test plate on the upper and lower grippers respectively. The testing machine disbonds continuously at a disbonding speed of 300mm/min +/- 10mm, and the disbonding Linear dispersion is drawn by the automatic recorder. The test results are calculated according to the distance of 20-80mm after peeling, and the values are read every 20mm within the disbonding range and averaged.
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
Fold the free end of the sample 180 degrees and peel it off from the test plate with a gluing surface of 25mm.
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. The testing machine continuously disbonding at a disbonding speed of 300mm/min +/- 10mm, and the automatic recorder plots the disbonding Linear dispersion.
4. The test results are calculated according to the distance between 20 and 80mm after peeling.
5. Within the disbonding range, read a number every 20mm, at least 4 numbers, and find the average.
6. The test is completed to calculate the results of different intervals and take point analysis, and generate print reports with A4 paper size and a variety of Linear dispersion analysis.
Notice
• Make sure that the free end of the sample is folded 180 degrees and peeled correctly, with a gluing surface of 25mm.
• When clamping the specimen, the disbonding surface must be consistent with the test machine line.
• The disbonding speed is controlled within the range of 300mm/min +/- 10mm.
• Test results are calculated based on a distance of 20-80mm after peeling.
• Read values every 20mm within the disbonding range, at least 4 to ensure accuracy.
• Safety protection device of test bench before use, including software automatic diagnosis and electronic limit function.
• Fixtures need to be customized according to user product sample requirements to ensure compatibility.
