Internal Ply Bond Tester: Top Choice in Seremban, Negeri Sembilan, Malaysia Eco Instrument

Description

Introduction:

The Touch Screen Internal Ply Bond Tester is a precision engineering instrument specifically designed to quantify the internal fiber bonding strength of paper, board, and other sheet materials. Adhering strictly to TAPPI T569, this system is essential for quality control and R&D laboratories aiming to predict material performance during high-speed converting, printing, and finishing processes.

The Science of the Test
This tester operates on the proven falling pendulum principle to simulate high-velocity impact forces:

Specimen Preparation: The sample is securely sandwiched between two substrates coated with high-tack double-sided tape (Figure 1), ensuring that the surface layers are held firmly during the test.

High-Speed Impact: A calibrated pendulum swings downward, striking the tape assembly at a controlled, high rate of speed (Figure 2). This sudden impact creates a tensile stress perpendicular to the sheet surface.

Measurement: The system measures the total kinetic energy absorbed by the specimen during the delamination event. This energy reading directly corresponds to the work required to split the internal fibers of the paper in the "Z-direction" (the thickness axis), forcing the single specimen to separate into two distinct piles

Applications:

Corrugated Board: Evaluating the ply adhesion to prevent delamination during fluting and laminating.
Coated Papers: Assessing the coating bond strength to avoid blistering in offset printing.
Tissue & Linerboard: Ensuring structural integrity during high-speed rewinding and converting.
