84-92 Lab Master Z-Directional Tensile Tester
Z-DIRECTION TENSILE STRENGTH
The measurement of Z-Directional tensile strength was developed to determine the structure of a sheet of paper or board when subjected to tensile stresses in the out-of-plane direction or Z-Direction. Z-Directional Tensile Strength is a measure of the internal fiber bonding strength of a substrate.
ZDT
Z Directional Tensile Strength is different than other conventional means of measuring maximum force (Tensile Strength) or internal bonding strength such as the Scott Bond method for materials strength testing. Other strength properties for this type of measurement include: internal bond strength, ply adhesion and ply bond strength.
LAB MASTER® ZDT
The Lab Master® ZDT Tester is a precision PC Controlled testing instrument which automatically determines internal bond strength according to TAPPI T 541. All testing parameters such as test speed, dwell time and compression force are selectable in an easy to use, intuitive software program supplied with the instrument.
PRECISION TESTING
Peak Force is measured to a maximum capacity of 1100 N (250 Lbs) with a 0.04 N (0.01Lbs) resolution and accuracy of ±0.5% of reading. Position is measured and controlled with 0.1μm resolution and 0.2 μm repeatability. Peak force is measured by applying a force in the z-direction until ply separation occurs.
APPLICATIONS
ZDT measurements are an effective tool for monitoring a variety of strength properties which aid in improving printing and coating applications, bonding strength of paper cores, delamination strength, intrinsic fiber bond strength, paperboard and combined board strength and fiber-to-fiber bond strength.
Lab Master® ZDT Advantages
- Windows® Environment – Extremely simple to operate, it works on Windows XP.
- Data Storage — Sample and Test Information is stored for future recall
- Presentation – Easy operation of test instrument using Touch Screen, Result and test curve/graph information is displayed on display
