Thwing-Albert's ZDT Tester is a compact, precision PC-controlled instrument that measures the internal fiber bond strength of paper, paperboard, liner board and coated fine papers. Z-Directional force provides an indication of expected material performance relating to glue-bonding of carton corners and seams, delamination, and the use of high tack coatings. The ZDT Tester is a fully automated instrument that performs sample compression, dwell time and ZDT according to TAPPI T 541. A self-adjusting test platen ensures uniform tension is applied to pull the sample apart.
Utilizing cutting-edge technology, all electronics and controls are fully integrated into the test frame. No external control boxes or additional PC interface cards are required enabling the connection to a standard PC with a serial port.
In order to maximize efficient use of lab space, the ZDT Tester is only 250 mm (10 in) wide and 419 mm (16.5 in) deep. A magnetic test-control keypad is easily moved to provide the most ergonomic positioning for the operator. Other benefits include one-touch auto zero and a software-based automatic calibration system.
ZDT application software, provided with the unit, utilizes MAP™, a Windows®-based materials testing software package. ZDT software enables the user to quickly set-up test parameters including compression force, speed, dwell time and length of test.
ZDT software also provides advanced capabilities for database management and reporting. Test comment fields allow the operator to enter information after the completion of the test indicating test failure or other pertinent details. ZDT software will automatically write result data to other software packages including Access™ and Excel™.
