Paper Bursting Resistance Tester: Test Method for Corrugated Paperboard Performance
Dongguan Haida Instrument 400-071-1808/0769-89280808
Second, the burst strength test
Instrument: HD-504-3 Rupture Strength Tester , also known as Burst Resistance Tester , Electronic Rupture Strength Tester , Burst Tester, Rupture Strength Tester , Burst Resistance Tester , Electronic Rupture Strength Tester, Resistance Penetration testing machine, rupture strength testing machine
The maximum pressure that a corrugated board can withstand evenly per unit area is the burst strength of corrugated board.
Each of the three sample boxes took four blocks of 140mm×140mm in size, no printing, no watermark, no crease or obvious damage.
The burst strength tester is a burst tester
The main technical parameters of the burst resistance meter are:

Breaking strength test method :
A ring is pressed firmly clamped can be raised and restored rubber membrane under the action of hydraulic pressure, a certain force to firmly fixed on the sample between the pressure ring through the rubber membrane so that again projections Cracked.
   The test specimens were divided into groups A and B. A group was attached to the rubber film on the front, and the B group was attached to the rubber film on the reverse side for testing. When the specimen breaks, read the displayed value. For the test results, find the arithmetic mean and keep the three significant figures.
   The hydraulic pressure of the bursting resistance meter is very important. The hydraulic system works normally to ensure that the hydraulic oil can meet the working requirements. The hydraulic main oil must be observed and measured frequently. Observe and measure the decrease in oil quantity to see if the hydraulic fluid deteriorates or is fouled by the operation.
