How to operate the Schober abrasion tester
The Schober abrasion tester uses a rotating wear method to test the appearance changes of fabric samples after friction or wear tests. It is mostly used for automotive interior material testing. During the test, the friction component applies friction to the rotating sample in the tangential direction to measure the wear resistance of the sample.
Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. was established in 2012. It focuses on the research and development, design, and production of textile testing instruments, and provides textile testing instruments and services for academic research units and testing institutions. Shanghai Qianshi is currently one of the most competitive and R&D-capable textile testing instrument manufacturers in China. The R&D team is composed of a group of experienced engineers. We are committed to serving customers wholeheartedly and striving to promote technological innovation in textile testing instruments.
According to standards:
DIN 53863.2, GME Standard 60345, GMW Standard 3283, VW/Audi Zentral-Norm PV 3908, etc.
Basic principle:
The round specimen is mounted on the rotating test head. The specimen is rubbed against the friction object (sandpaper) in clockwise and counterclockwise directions at a certain speed, pressure, and number of rotations by using rotational wear. The friction object maintains linear contact with the specimen, so a friction effect in the tangential direction can be produced. The rotation direction is changed every 100 frictions (settable). The test results are evaluated by mass loss and the generation of holes.
Operation method:
Use the accessories configured by the instrument to install the temperature and humidity-treated specimen on the specimen fixture to form a rotating test head. Use the arch height test device to adjust the protruding height of the test head according to relevant standards or other specified requirements, generally 5 to 8 mm.
Install the test head with the sample on the test head mounting plate on the instrument workbench, and install and tighten the test head through the positioning pin on the mounting plate and the positioning hole under the test head.
Use the friction fixture on the instrument pressure plate to install the friction sandpaper on the lower surface of the pressure plate, and lock the fixture to ensure that the sandpaper is clamped and installed flat.
Pull the pressure plate lifting lock on the right side of the pressure plate manually to lower the pressure plate so that the sandpaper contacts the surface of the sample on the test head.
Install the weight of the corresponding weight on the weight shaft above the pressure plate (the instrument is equipped with one standard weight of 1500, 1000, 500, 250, 100, and 50g each) to apply a certain pressure to the sample friction. Select the pressure value to be applied according to the weight of the sample per unit area.
