The main differences between paper and cardboard tolerance tester:
High -pressure break -resistant instruments used in cardboard, low -pressure break -resistant intensity instruments used in paper.
The motor is different, the upper and lower pressure plates are different, the rubber film is different, and the oil pressure rate is different. Others are the same!
1. Usually cardboard and cowhide (hanging paper) is a high -pressure rupture strength tester with a speed of (170 plusmn; 15) ml/min;
The test instrument of the paper It is a low -voltage tester with a speed of 96 plusmn; 6ml/min.
2. The sloping size of the high -voltage rupture strength tester is slightly greater than the low -voltage tester.
3. Paper tolerance test standards GB/T454-2002 Paper to resistance 70 --- 1400kPa
Cardboard breakout test standard GB/T1539-1989 Broken Determination of Cardboard 350 --- 5500KPa
