Carton is an important packaging material and an important part of modern logistics. It has the appearance of beautiful appearance, protects products and holds products. The physical performance index of the carton becomes the basis for its quality assessment. The physical indicators mainly include the rupture strength of the carton and the compressive strength of the carton. Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. is a professional manufacturer of packaging material testing instruments in China. The carton burst strength testing machine produced by our company can detect the bursting strength of carton. The following small series briefly introduces how the carton burst strength testing machine can detect the bursting strength of the carton?
Carton burst strength testing machine
  The carton is a wide range of packaging products using Zui. There are corrugated boxes, single-layer cardboard boxes, etc. according to different materials, and there are various specifications and models. It is an indispensable part of modern logistics. It bears the important responsibility of packaging, protecting products and aesthetics. The physical performance index of packaging carton is the basis for its quality assessment. Carton can be divided into three types: A type, C type, and B type. In actual production, different types of sputum can be selected according to specific conditions. The national standard GB/T6545 specifies a method for determining the burst strength of corrugated board by the hydraulic increase method.
  The following small series according to the requirements of GB/T6545 standard, briefly introduce how the carton burst strength testing machine detects the bursting strength of the carton;
  First, the experimental principle
  Place the sample on the film, clamp it with the sample, and apply pressure evenly so that the sample and the film are free to bulge until the sample breaks. The sample burst strength is a large value of the applied hydraulic pressure.
  Second, experimental instruments;
  The carton burst strength testing machine NPD-3000 is suitable for the burst strength test of all kinds of paperboard. Its performance parameters and technical indicators are in accordance with GB/T6545 "Determination of Cardboard - Burst Strength", ISO2759 "Cardboard - Determination of Burst Resistance" 》, GB1539 "Cardboard hardness test method" and other standard regulations and requirements. The NPD-3000 carton burst strength testing machine adopts microcomputer control. The liquid crystal displays the whole experimental process and the test results are automatically printed. It is a high-performance lightweight and burst-resistant strength experimental instrument, which is widely used in various quality inspection institutions, carton factories and other units.
  Third, the pattern processing
  The sample area must be larger than the chuck of the carton burst strength tester. The sample must not have watermarks, creases or obvious damage. Do not use specimens that have been pressed by the chuck during the test.

  Fourth, the experimental steps
  1. Open the chuck of the sample, clamp the sample in the middle of the two sample chucks, and then start the analyzer to gradually increase the pressure at (170 ± 15) ml / min.
  2. When the sample is blasting, read the value indicated on the pressure gauge. Then release the chuck and return the reading pointer to the starting position. The sample should be discarded when the sample has a significant slip.
  V. Experimental results
  The measurement was carried out on each of the ten samples attached to the film on the front and back sides, and was expressed by all measured values ​​and arithmetic mean values ​​(kpa).
  The above is a brief introduction of the experimental method of the carton burst strength tester on the bursting strength of the carton. For details, please contact Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd.
