Overview
The JW-110A interlayer disbonding tester is a professional testing instrument of the JINGWEN brand. It is mainly used to determine the Z-direction Tensile Strength (ie Internal Bond Strength) of paper and Cardboard, reflecting its ability to resist interlayer separation and internal bond strength. Precise control of internal bond strength is essential for multi-layer paper and cardboard processing. Too low or uneven distribution may lead to printing problems. If it is too high, it will increase the processing difficulty and cost. It is widely used in multi-layer Cardboard such as box Cardboard, white Cardboard, gray board, White Cardboard, etc. in the printing and Encasement industries.
Features
1. Adopt electric hydraulic pressurization device to avoid manual labor.
2. Equipped with a 3.5-inch LCD screen display and a thermal printer, the printing speed is silent.
3. Support RS232 communication output and USB optional interface.
4. Measurement range, 20~ 1000J/m ², resolution up to 0.01J/m ².
5. Impact angle is fixed at 90 °, and the number of samples supports 5 groups.
6. Indication Error is small, only +/- 1 J/m ² to ensure Test accuracy.
Principle
The instrument applies pressure through an electro-hydraulic system, performs interlayer disbonding tests on 25.4 * 25.4mm samples at a 90 ° Impact angle, and measures the Z-direction Tensile Strength of paper and Cardboard, that is, the internal bonding strength, reflecting the material's ability to resist interlayer separation.
Applications
Printing, Encasement Industry
Standards
GB/T 26203、TAPPI T-569
Steps
1. Prepare a 25.4 * 25.4mm sample.
2. Install the specimen into the instrument.
3. Test by applying pressure through an electro-hydraulic system.
4. Observe the LCD display data.
5. Use the thermal printer to output the results.
Notice
• The operating environment should meet the indoor temperature (20 +/- 10) ℃, relative humidity < 85%.
• Power supply voltage in the AC (100~ 240) V range.
• Avoid use outside the Force Measurement range (20~ 1000J/m ²).
• Regularly check instrument accuracy, Indication Error no more than +/- 1 J/m ².
