Pneumatic bursting strength tester
China national patent：ZL201210486480.8 ZL201220628425.3
[Scope of application]:
It is used to measure the burst strength and burst expansion degree of various fabrics,
including knitted fabrics, woven fabrics, non-woven fabrics, laminated fabrics and other
fabrics made by other processes, under standard conditions or wet conditions.
This method is employed to assess the burst strength and degree of burst expansion of various types of fabrics, such as knitted, woven, non-woven, laminated, and others produced through different processes, under both standard and wet conditions.
This technique is utilized to evaluate the burst strength and extent of burst expansion in various fabric types, including knitted, woven, non-woven, laminated, and others produced through diverse manufacturing processes, under both standard and wet conditions.
Benefits of Bursting strength tester:
Fast testing cycle for fast feedback to the production • Auto-start, a photocell detects the presence of a sample and automatically initiates a measurement sequence, thus allowing hands-free operation • Auto-cycling function permits the continuous cycling of the upper pressure foot to facilitate representative and continuous measurements
- Available with automatic test strip feeder Measurements are simple to make with the Mullen type Bursting Strength Tester. Fast automatic measurements Measurement starts automatically once a test piece has been placed in the measuring gap. The clamping foot descends, and a bursting strength measurement is made.
The sample is then quickly released and is ready for the next measurement at a new position. To maximize the sample measurement rate, the tester uses a minimum of time between the bursts, so that a series of 10 measurements can be done in less than 45 seconds. The actual measuring time depends of course on the type of paper or paper board being tested. Three
Different test results can be reported after a single measurement; bursting strength standard, bursting strength compensated, and bursting energy absorption (BEA).Bursting strength tester can be compensated for the stiffness of the diaphragm For low bursting strength levels, the stiffness of the diaphragm can account for a large portion of the bursting strength value. If desired, the device can also measure, calculate, and report effective bursting strength compensated from the effects of the diaphragm.
Measurement of Bursting Energy Absorption (BEA) is used to determine the energy absorption capability of a material. Strong, flexible paper has higher energy absorption values, while brittle, stiff paper has lower values. Bursting Strength Tester calculates and reports BEA according to the SCAN P 24 standard
