The function of the paper burst tester and how to calibrate it ( What is a burst tester )

    What is a Bursting Resistance Meter: A dedicated testing instrument for the detection of the bursting resistance of paper, cardboard, and corrugated board. The currently used bursting resistance meter is a Mullen type bursting resistance meter.

    Definition of bursting resistance: The maximum pressure at which the elastic film breaks through the circular area of ​​the pattern when pressure is applied by the hydraulic system.

    The definition of the burst resistance index: Burst resistance divided by its ration.

     The working principle of the Bursting Resistance Meter is based on Pascal's Law: The pressure applied to a closed liquid can be transmitted in all directions by the liquid in accordance with the original size. In the chamber of the instrument's sealed cylinder and platen, filled with methyl silicone oil as the medium for pressure transmission. When the motor drives the piston to advance at a uniform speed, the film is pressurized by silicone oil and protrudes; Above, the sample fixed by the upper and lower chucks is evenly stressed until the specimen ruptures. The processing chip locks the maximum pressure value and displays the pressure value through the LCD screen. This pressure value is the bursting resistance of the sample.

    So how to calibrate the burst resistance meter, in fact, the national relevant verification procedures, light industry standards, GB/T1539 national standards have already clearly defined the calibration method - the standard accuracy of not less than 0.1% of the load cell, to show Correct the value error. If the calibration is not carried out according to this method, it is an invalid proofreading that does not conform to the regulations (such as the so-called “aluminum foil calibration sheet” that circulates on the market at present. This aluminum foil can only be used as a fixed-value sample to measure Or called dynamic comparison, and can not be used as a basis for the calibration of the data, because the accuracy of aluminum foil does not reach 0.1% at all , so please be cautious when using or buying the Burst Tester.
