Automatic High Pressure Paper Mullen Burst Testing Equipment

Automatic High Pressure Paper Mullen Burst Testing Equipment   1. INTRODUCTION: This is Automatic High Pressure Paper Mullen Burst Testing Equipment  It is a new type testing machine to test the bursting strength of corrugated boards, which is designed in accordance with related ISO standards and on the principle of modern mechanical design concept and design criterion of human-machine engineering. PN-BSM600 Bursting Strength Tester belongs to electromechanical product which is with novel design, convenience for use, excellent performance and elegant appearance. Digital mullen packaging burst tester for mullen bursting test has abundant functions, such as, parameter testing, parametric transformation, parameter adjusting, parameter memory and parameter print. All are in accordance with related ISO standards.  Digital mullen packaging burst tester for mullen bursting test has data processing function which can directly output result of data statistics with convenient operation, easy regulation and stable performance.   2. PRINCIPLE: The principe of  Digital mullen packaging burst tester for mullen bursting test : A test piece placed over a circular elastic diaphragm, it is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate,  and bulged the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.    3. APPLICATIONS: Corrugated cardboard, Corrugated Package.   4. STANDARDS: ISO 2759   5.
