Model 1314 Internal Bond Tester, utilizes the Scott method to produce a high speed Z-direction rupture of paper and paperboard. It is a dynamic test that measures and defines strength in terms of energy absorption.
Ideal for monitoring the effects of dry strength additives and to evaluate stock preparation and refining. In addition to correlations with customer complaints, in-mill processing trouble-spots are of growing interest. Examples of dry-end analysis are monitoring Z-direction strength deterioration due to calendering or the application of relatively brittle coatings. The increasing use of recycled fiber and dry strength additives in both paper and board open even more applications and create economic value for the test today. At the product research and development level, sequential photographs of the ruptures can further enhance analysis and understanding.
