PN-IBTF internal bond tester is a paper and cardboard internal bond detection tester designed and developed by our company according to the latest national standard GB / T 26203. It is mainly suitable for single-layer and multi-layer paper and paperboard, including coated paper and paper and paperboard with synthetic polymer surface. The tester uses the Scott-type internal bonding strength detection method. The detection principle is: a combination of double-sided tape---sample----double-sided tape forms a sandwich structure, and the sandwich is pressed between a metal flat anvil and an aluminum block. Use a pendulum to strike the inner surface of the upper part of the aluminum block, flip the aluminum block, and damage the sample in the Z direction. Calculate the energy absorbed during the destruction of the sample by measuring the highest position of the swing, expressed in J / m
2.
The instrument adopts a split structure, and the sample preparation adopts pneumatic sample preparation, which is clean and environmentally friendly; Pneumatic clamping is used for specimen clamping, and the clamping pressure is constant. The swing arm adopts an electromagnet for attracting, which release automatically when press the test button.
The instrument is an electromechanical integration product. It adopts modern mechanical design concepts and ergonomic design principles, and uses advanced and high-speed ARM processors. The tester has the functions of parameter testing, display, memory, and printing included in the standard. With data processing function, it can directly get the statistical results of various data, and can automatically reset, communicate with the host computer, convenient operation, easy adjustment and stable performance.
