Overview
Microcomputer Internal Bond Strength instrument is mainly used for the determination of the internal bond strength of paper and Cardboard. It is suitable for single-layer and multi-layer paper and Cardboard, including Spreader paper and paper and Cardboard with synthetic polymer film on the surface. It can be used for paper mills and Cardboard mills to conduct tests on the internal bond strength of paper. Not suitable for low Basis Weight, porous, soft or low density paper and Cardboard. Internal Bond Strength refers to the ability of paper and Cardboard to resist interlayer separation. It is a reflection of the internal bonding ability of paper and Cardboard. The internal bonding strength can be completely controlled, which is very important for processing multi-layer paper and cardboard.
Features
1. Microcomputer control, easy to operate
2. Measurement range: A gear (20~ 500) J/m ² and B gear (500~ 1000) J/m ²
3. High resolution: 0.1J/m ²
4. Adjustable sample holding force: 0~ 40kg/cm ²
5. Equipped with 3.2-inch LCD screen
6. Built-in modular integrated thermal printer
7. Support unit conversion: J/m ² and lbf/in ²
Principle
The instrument measures the Internal Bond Strength by Impacting the specimen and measuring its ability to resist interlayer separation at an Impact angle of 90 °, detects the separation force using a sensor, and calculates the internal bond strength value.
Applications
Interlayer bonding of bobbin base paper, interlayer bonding of White Cardboard, interlayer bonding of kraft cardboard, interlayer bonding of boxboard paper, aluminum foil
Steps
1. Prepare the sample size to be 25.4 * 25.4mm
2. Adjust the sample holding force to the required range of 0~ 40kg/cm ²
3. Select measurement gear (A or B)
4. Impact testing
5. Read the Internal Bond Strength value on the display
6. Use Built-in Printer to output results
Notice
• Not suitable for Low Basis Weight, Porous, Soft or Low density Paper and Cardboard
• power requirements AC220V +/- 22V, 50Hz, maximum current 3A, must be reliably grounded
• Ensure that the sample size is accurate to 25.4 * 25.4mm
• Choose the appropriate measurement gear according to the material strength to avoid errors
• Regularly check the instrument accuracy, Indication Error A file is +/- 1J/m ², B file is +/- 2J/m ²
