PUYUN PY-H602B Automatic Burst Strength Tester (paper type) ≤ 1600Kpa paper breaking resistance

Applications

PY-H601 Cardboard Burst Strength Tester is a testing equipment independently developed by our company to test the bursting strength of paper and cardboard, corrugated cardboard and cartons. The Burst Tester is equipped with kpa, gf/cm2, Lb/in2, etc. Several testing units, the paper Burst Tester is used for the determination of the bursting strength and bursting index of paper, suitable for cardboard, kraft paper, cardboard, corrugated paper, gray board, etc. The corrugated cardboard Burst Tester is used for the determination of the bursting strength of corrugated cardboard and corrugated boxes. The instrument is suitable for cardboard production enterprises, carton production enterprises, carton user enterprises, scientific research institutions and other units.

According to the standard

GB/T 454 "Determination of Bursting Strength of Paper" ISO 2758 "Paper - Determination of Bursting Strength" QB/T 1057 "Burst Resistance Tester of Paper and Cardboard"

Main Operation Guidelines

Select specimens from the same batch of specimens, no less than 10 groups of specimens, measure with 10 specimens attached to the film on the front and back sides, and express it as the arithmetic mean (kpa) of all measured values.

Use a standard cutter and a test piece cutting machine to cut the standard specification test piece required by your company (the sampling position must be the middle part without damage), the sampling size is greater than or equal to 70mm×70mm, or the entire sample can be tested directly.

Open the chuck of the sample, clamp the sample in the middle of the two sample chucks, then start the measuring instrument and gradually increase the pressure at a speed of (170±15)ml/min, when the hydraulic fluid is pumped in at a steady rate, Let the sample protrude freely together with the adhesive film until the sample breaks, and the maximum value of the applied hydraulic pressure is the bursting strength value of the test piece.

The result says:

Burst resistance index X=P/g (burst resistance index should retain three significant figures);

P---average bursting strength, the unit is kilopascal (KPa);

g---quantity of cardboard, the unit is per square meter (g/m2)
