Analyze the difference in the measurement of the burst strength of paper and paperboard

The high-pressure burst strength instrument used for cardboard, and the low-pressure burst strength instrument used for paper.

Different rubber diaphragms, different oil pressure rates. The other is the same!

1. Usually paperboard and kraft paper ( noodle paper ) is a high-pressure burst strength tester with a speed of (170 ± 15) mL/min ;

The test instrument for paper is a low pressure tester with a speed of 96 ± 6 mL/min .

3 , the paper's burst test standard GB/T454-2002 "Determination of Bursting Strength of Paper" 70---14000KPA

Cardboard burst test standard GB/T1539-1989 "Determination of Bursting Strength of Paperboard" 350---5500KPA

Computer cardboard burst tester

PN-BSM600

Computer paper burst tester

PN-BSM160

The paperboard bursting resistance meter is a new generation paper testing instrument developed and produced by our factory. It adopts a measurement and control method based on a single-chip microcomputer, thereby realizing all digitization and microcomputerization of detection, control, and data processing. The technical parameters and performance indicators are in line with the standards and requirements of ISO2759 "Determination of the Rupture of Paperboard", QB/T1057 " Burning Instrument for Paper and Board" and GB1539 "Test Method for Bursting Strength of Paperboard". The instrument is simple, reliable performance, advanced technology, is an ideal equipment for scientific research units, paper manufacturers, packaging industry, quality inspection departments indispensable.
