Working Principle Of Flat Crush Testing Machine

Working Principle Of Flat Crush Testing Machine

Instrument introduction：

Flat crush testing machine, this series tester can be matched with various materials to do comprehensive testing, in terms of paper packaging material, for a variety of test paper quality, the ring pressure (RCT), pressure (FCT), side pressure (ECT), adhesive (PAT) and 5 (CMT) compression a test is a test equipment of combining multiple functions in a body.

Working principle：

1, RCT - ring crush test

Paper or paperboard samples in special ring sampler punch, size: 152mm * 12.7 mm, the sample is placed in the center of the circular plate, pressing test instrument, and then placed in the compression plate, the edge of the sample under increasing pressure, until the collapse.

2, CMT -compression test of corrugated paper

The size of corrugated paper sample 152mm * 12.7 mm heated up in the corrugated groove instrument, with a fixed side tape, flat on the compression device and a lower pressing plate between the crushing test sample under increasing pressure, until the collapse.

3, ECT-corrugated board edge pressure test

Corrugated cardboard marginal pressure strength test and pressure test of corrugated cardboard (bonding) sampler cut 100mm * 25 mm, vertical compression apparatus on upper and lower pressure plate between the crushing test, until the collapse. The ECT value can be expressed as divided by the length of specimen.

4、PAT - corrugated board bond strength test

Corrugated cardboard samples of 4 and PAT corrugated board adhesive strength test of 25 100mm * mm placed in the peel strength test frame, pressure test instrument, then placed in the compression plate, with special structure and length of needle peel strength test frame, the specimen surface layer and core layer separation, separation when required the maximum force value.

5, FCT-corrugated cardboard flat compression strength test

Flat specimen sampler cut from a certain area of corrugated cardboard samples, flat on the compression device and a lower pressing plate between the crushing test sample under increasing pressure, until the collapse, the maximum force per unit area.
