SKZ108AB Mullen Bursting Tester
SKZ108A/B Mullen Bursting Tester is a basic instrument for testing the strength of paper and paperboard. Its various performance parameters and technical indicators in line with ISO2759 "paperboard - determination of break resistance", GB1539 "Paperboard - determination of break resistance" and ISO2758 "paper - determination of break resistance" and GB454 "paper - determination of break resistance" and other standards and requirements, suitable for all kinds of paper and paperboard break strength test.
The definition of rupture resistance: the maximum pressure exerted by the hydraulic system when the elastic film breaks the circular area of the paper pattern.
The definition of the break resistance index: the break resistance divided by its quantity.
The working principle of the breakage meter is based on PASCAL's law: the pressure added to the closed liquid can be transmitted in all directions by the liquid according to the original size. The chamber of the instrument seal cylinder and the paper press seat is filled with methyl silicone oil as the medium for pressure transfer. When the motor drives the piston to advance at a constant speed, the film is pressurized by silicone oil and rises; At this time, the sample held above the film and fixed by the upper and lower chuck is stressed evenly until the sample breaks. The processing chip locks the maximum pressure value and displays the pressure value through the LCD screen, which is the burst resistance of the sample.
