TMI 80-20 Internal Bond Tester

Product Ref: TMI 80-20

The Internal Bond Tester is designed to determine the internal bond strength of a variety of Paper and Board materials according to TAPPI T 569.

Introduction

The Internal Bond Tester is designed to determine the internal bond strength of a variety of Paper and Board materials according to TAPPI T 569. The instrument design is based on a falling pendulum which creates a high speed impact on a paper specimen. The paper specimen is sandwiched between two double-coated tape substrates. The pendulum impact measures the total energy required to delaminate the internal fibers of a specimen in a "Z" type direction into two separate piles. The system also incorporates an automatic sample preparation station which allows five specimens to be accurately prepared simultaneously.

The Prep Station requires a filtered air supply meeting IG4 Industrial Grade Air: ISO Class 1-4-1

Sample Prep Station

A precision sample Preparation station with digital display and direct read out in kPa and psi units is available to prepare up to 5 test pieces at the same time. The Sample Prep Station is supplied to provide a consistent adhesive transfer when pressing the test specimen between the double-sided tape and aluminum platens.

Included with the Sample Prep Station are 5 aluminum platens with a sample size of 25.4 x 25.4 mm (1.0 x 1.0 inches). The clamping pressure is adjustable from 345 kPa (50 psi) to 1379 kPa (200 psi). During the pressing operation a selectable dwell time can be set by the operator from 0-4 seconds. The factory setting is 3 seconds in accordance with TAPPI T 569. The system is designed with a reinforced anvil to prevent deflection during sample preparation.
