bursting strength tester

Introduction of breaking strength testing machine:

        The breaking strength testing machine, also known as the blasting machine or blasting instrument, is an international universal Mullen type instrument, widely used in packaging materials, mainly used to determine a variety of cardboard and single-layer and multi-layer corrugated board, but also can be used for silk, cotton and other non-paper materials to test the breaking strength. Blasting machine is to test the rupture strength value of the product, the digital display pressure, when the test material is broken, automatically retain the large rupture   strength value, at the same time can trend print the detection results. The indication mode of the rupture strength tester is digital type, and the capacity is 0-100kg/cm2.

Scope of application of breaking strength testing machine:

   Mainly used for the determination of various kinds of cardboard and single and multi-layer corrugated board, can also be used for silk, cotton, leather, cloth, packaging film and other non-paper materials breaking strength test.

Blasting machine standard: a wrench, special glycerin 1 bottle, correction sheet (blasting machine aluminum sheet) 10 pieces, 1 piece of rubber film.

Advantages of blasting machine:

The blasting machine has simple operation and accurate data. As long as the material is put in, automatic detection, automatic test, automatic oil pressure return and automatic calculation, storage of test data, printing (optional), the instrument with digital display and can automatically print test results and data processing.

Notes on the use of breaking strength testing machine:

1. The blasting machine must be placed on a stable table and maintained in a good ventilated environment before use. It is not allowed to move the blasting machine during use;

2. Use the blasting machine to select the corresponding power supply voltage, do not be too high, avoid burning devices, key mechanical components, due to the large running load, mechanical part please add lubricating oil in time; When the blasting machine abnormal, please contact the institute for timely processing;

3. After the completion of the blasting machine test, it should be cleaned in time and kept clean; The control box of the blasting machine should be wiped with dry cloth, not wet cloth.

Experimental principle of breaking strength tester:

    The sample is placed on the elastic film between the upper and lower collet, the upper and lower collet is pressed, the hydraulic fluid is pumped at a stable rate, when the sample is broken, the adhesive film protrudes large pressure is the sample breaking strength.
