The Difference Between Hammer Cloth Tear Tester and Manual Tear Strength Tester

The fabric tear tester has hammer type and manual type, which is composed of pendulum frame, pendulum shaft, pendulum body, compatibilizer, a fixture, movable fixture, punch, pendulum release mechanism, sample notch and locking system, is a test equipment independently developed and produced by our company Qisnun Precision Electromechanical Technology Co., Ltd., with high cost performance and comprehensive after-sales service. The test equipment is used to determine the degree of tearing of paper and cardboard, film and foil, fabric and rubber or plastic coated fabric, the results are used to judge the quality of paper and cardboard, film and foil, fabric and rubber or plastic coated fabric Important basis, the precise determination of the tear strength is of great importance for the controlthe quality of products and the improvement of product performance.

Fabric Tear Tester Operation:

(1) Place the moistened sample into the device center and clamp the sample along a flat surface to avoid wrinkles. Place the test cup on the test sample.

(2) Move the handle to the left to unfold the film.

(3) When the film expands, fix the pin on the lower or right side of the rod.

(4) When the sample breaks, try to turn the bolt so that the lever returns to the middle position. Record the total pressure required to rupture the sample.

(5) After the sample is broken, the clamp on the sample is quickly released, the bolt swings to the normal position, the pressure on the membrane is eliminated, the lever is pushed to the right and the pressure required for expansion of the membrane isrecorded.

Manual Tissue Tearing Instrument Operation:

1. Install the specimen, place the wet sample in the handles, clamp the sample along a flat surface to avoid wrinkles. Place the test cup on the test sample.

2. Rotate the handwheel

(1) Rotate the handwheel cclockwise at 20 rpm until the sample breaks .

(2) Stop turning the handwheel when the sample breaks.

(3) After the sample breaks, quickly loosen the clamp on the sample and turn the handle counterclockwise starting point, the membrane is allowed to expand, the pressure required to expand the membrane is recorded, and the total pressure required to rupture the sample is recorded.

(4) Note that if the pressure on the dial stops increasing but the sample does not break, push the lever in.ur remove the pressure. Record the elongation of the specimen beyond the tester\'s measurement.
