Overview
YN-226 Microcomputer Interlayer bond strength tester (Peel Strength tester) is used to detect paper and Cardboard Internal Bond Strength, which can be used to detect the internal bond strength of paper composites, film composites and other sheet materials at the same time. The instrument adopts Scott type internal bond strength detection method.
Features
1. Adopt Scott type internal bonding strength detection method.
2. Equipped with a 3.2-inch LCD screen to display test data in real time.
3. Adopt fully automatic release mode.
4. Equipped with a modular integrated thermal printer.
5. You can choose computer connection software to support office document processing and end point A4 printing.
6. Adopt 5000 pulse high-precision encoder with a resolution of 0.001lbf/in ².
The sample holding force can be adjusted from 0 to 400N.
8. Have a special 5-level calibrating tool set (additional) for self-calibrating.
Principle
The detection principle of the instrument is as follows: The combination of double-sided tape-sample-double-sided tape forms a sandwich structure, which is pressed between a metal flat anvil and an aluminum block. Impact the inner surface of the upper part of the aluminum block with a pendulum to make the aluminum block flip and destroy the sample in the Z direction. Calculate the energy absorbed during the destruction of the sample by measuring the highest position of the swing, expressed in J/m ².
Applications
Bobbin Paper, Paper Tube Paper, Kraft Paper, Various Gray Cardboard, Cardboard, Composite Cardboard, Kraft Paper, White Card, Whiteboard Paper, Encasement Color Box, Cigarette Case, Cigarette Paper, Wood
Standards
GB/T 26203、ASTM T569 pm-00
Steps
1. Prepare the sample, the size can be 25.4 * 128mm or 25.4 * 25.4mm.
2. Use double-sided tape to combine the sample with aluminum block and metal flat anvil to form a sandwich structure and press it tightly.
3. Clamp the combined specimen on the instrument and adjust the clamping force (0~ 400N) as required.
4. Set and apply the usual specimen pressure (690 +/- 21) kpa or (1034 +/- 34) kpa).
5. Start the instrument, and the pendulum will automatically hit the aluminum block, destroying the sample.
6. The instrument automatically calculates and displays the energy absorbed by the damaged specimen (J/m ² or lbf/in ²).
7. The test data can be printed through the thermal printer, or connected to the computer software for data processing.
Notice
* The maximum sampling thickness of the sample is 1.2mm.
The commonly used sample pressure is (690 +/- 21) kpa or (1034 +/- 34) kpa, please choose according to the standard or requirements.
The sample holding force can be adjusted within the range of 0 to 400N.
* Measurement range is divided into A file (0~ 500 J/m ²), B file (500~ 1000 J/m ²), C file (1000~ 1500 J/m ²), please select the appropriate gear according to the sample strength.
* Instrument Indication Error: A file +/- 1J/m ², B file +/- 2J/m ².
The adhesive force of double-sided adhesive should be greater than 486N/m.
* For High Accuracy calibrating, a special 5-level calibrating tool set is required.
* The instrument weight is 70Kg, please pay attention to safety when handling and placing.
