NPD-D Rupture strength testing machine
Rupture strength testing machine Application and scope of application:
The bursting strength testing machine is the basic instrument for testing the strength of paper and paperboard. Its performance parameters and technical indicators meet the requirements of iso2759 "paperboard - Determination of bursting strength", gb1539 "determination of bursting strength of paperboard", iso2758 "paper - Determination of bursting strength" and gb454 "determination of bursting strength of paper", Bursting tester for paperboard It is mainly used to determine the bursting strength of various kinds of paperboard, single-layer and multi-layer corrugated board, as well as non paper materials such as silk and cotton cloth. The instrument is simple in operation, reliable in performance and advanced in technology. It is an indispensable ideal equipment for scientific research institutions, paper mills, packaging industry and quality inspection departments.
Bursting tester for paperboard working principle:
A uniform fluid force is applied to the test sample through an elastic diaphragm The sample * is flat at first and clamped with a certain pressure, but the center has a certain cross-sectional area. The value can be measured with the elastic diaphragm arbitrarily uplifted, and the value includes the pressure required to elongate the diaphragm in the test The pressure measured by the instrument according to this principle is the bursting strength of the tested sample
Bursting tester for kraft paper characteristic:
1. The design of the whole machine is simple and compact, with small volume and light weight;
2. It is driven by synchronous motor. The transmission is stable and accurate, making the output pressure more * *;
3. This machine is equipped with a printer to eliminate the interference of human factors to a large extent.
4. The instrument has the functions of parameter test, memory, printing and so on.
5. LCD display, automatic reset, easy to operate, easy to adjust, stable performance, advanced technology.
