Paperboard Bursting Strength Tester

Product Introduction:

    Paperboard bursting strength tester can be widely applied to packaging materials, including general paper, corrugated paper, toilet paper, wrapping paper, etc., for leather, cloth, packaging film, etc., which can effectively monitor product quality.This instrument is an internationally-used Mullen-type instrument. It is widely used in packaging materials. Bursting strength tester is mainly used to measure various cardboard and single-layer and multi-layer corrugated cardboard. It can also be used for resistance to non-paper materials such as silk and cotton. Break strength test. As long as the material is placed, it is automatically detected, automatic test, automatic oil pressure return and automatic calculation, storage test data, printing, digital display of the instrument and automatic printing of test results and data processing.

Working Principle:
A constant velocity fluid force is applied to the sample to be tested through an elastic diaphragm. The sample is initially flat and clamped with a certain pressure, but the center has a certain cross-sectional area and can be arbitrarily raised with the elastic diaphragm. , to determine the maximum pressure it can withstand, this value includes the pressure required to stretch the diaphragm in the test. The pressure measured by the instrument using this principle is the burst strength of the test sample.
