The Internal Bond Tester (Scott Type) is a precision instrument engineered to evaluate the delamination resistance of paper, board, and laminated materials.
By utilizing a high-speed pendulum impact, this tester measures the internal bonding strength in the "Z" direction, providing critical data for quality control in the printing and packaging industries.
Designed for durability and repeatability, it ensures your products meet rigorous structural requirements during high-speed converting processes.
This essential testing equipment allows manufacturers to optimize fiber bonding and additive efficiency while strictly adhering to international testing protocols for consistent, reliable performance.
Internal Bond Tester: Frequently Asked Questions
What is the purpose of an Internal Bond Tester?
The Internal Bond Tester is used to determine the internal bonding strength of paper, board, and laminated materials. It measures the energy required to delaminate the internal fibers of a specimen in a "Z" direction (thickness) using a high-speed pendulum impact, which helps manufacturers predict performance during printing, coating, and converting processes.
Which testing standards does this Internal Bond Tester comply with?
Our Internal Bond Tester is designed to strictly conform to international industry standards, specifically TAPPI T 569 and ISO 16260. These standards ensure that the internal bond strength (also known as Scott Bond) is measured accurately and consistently across different laboratories and production batches.
Why is the Scott Bond test important for paper and board manufacturers?
The Scott Bond test is critical for identifying potential failures such as blistering in coated offset grades, picking, and ply separation. By measuring energy absorption, manufacturers can monitor the effectiveness of dry strength additives and evaluate how refining or calendaring processes affect the structural integrity of the paperboard.
How does the automatic sample preparation station improve results?
The automatic sample preparation station (Model IBP-5A) ensures higher accuracy by applying consistent pressure and timing when bonding the tape to the specimen. This reduces human error and has been shown to decrease the standard deviation of test results by up to 20%, providing more reliable data for quality control.
What units of measurement are used for internal bond strength?
The instrument features a digital display that allows users to select between several standard units of measurement, including J/m² (Joules per square meter), ft.lb/in² (foot-pounds per square inch), and kg•cm. This flexibility ensures compatibility with various international reporting requirements.
Can this tester handle different material thicknesses?
Yes, the Internal Bond Tester is designed for a wide range of materials, including newsprint, fine paper, liner board, and heavy carton board. It features interchangeable pendulums with different energy ranges (0-400, 150-750, and 200-1000 ft.lb x 10⁻³) to accommodate varying material resistances and thicknesses.
How do I maintain the calibration of the Internal Bond Tester?
To ensure long-term precision, IDM Instruments provides a specialized Calibration Block Set. This set allows operators to verify the force and operation of all three pendulum ranges. Regular use of these verification blocks ensures the system is operating within specification and provides a "proven method" for audit compliance.
