Schobrill wear tester adopts the method of rotary wear to test the appearance of the fabric after friction or wear test, and is mostly used for automotive interior material testing
.
During the test, the friction parts apply friction to the rotating specimen in the tangent direction to determine the wear resistance of the specimen, which is the test equipment independently developed and produced by Shanghai Qianshi Precision Electromechanical Technology Co.
, Ltd.
, which is cost-effective and has complete
after-sales service.
Applicable standards: DIN 53863.
2, GME Standard 60345, GMW Standard 3283, VW/Audi Zentral-Norm PV 3908GMW 3283-2001, DIN 53863-2:1979, QC/T 216-1996 and other standards Test principle: Round specimen mounted on a rotary test head, Specimens are rubbed against friction (sandpaper) at a clockwise and counterclockwise direction at a certain speed, pressure and number of rotations by using rotational wear
.
The friction material maintains a linear contact with the specimen and therefore produces a friction effect
in the direction of a tangent.
Change the direction
of rotation every 100 (settable) frictions.
Test results
are evaluated by quality loss and the generation of holes.
Operation method: 1.
Use the accessories configured by the instrument to install the sample that has been treated with temperature and humidity on the specimen fixture to form a rotating test head
.
And use the arch height test device to adjust the protruding height of the test head according to relevant standards or other requirements, generally 5 ~ 8mm; 2.
The test head mounted on the specimen is installed on the test head mounting board on the instrument table, and the test head is installed and fastened by the positioning pin on the mounting plate and the positioning hole under the test head; 3.
Use the friction clamp located on the pressure plate of the instrument to install the friction sandpaper on the lower surface of the pressure plate, and the locking fixture ensures that the sandpaper is clamped and installed smoothly; 4.
Manually pull the pressure plate lifting lock located on the right side of the pressure plate to lower the pressure plate so that the sandpaper is in contact with the surface of the specimen on the test head; 5.
Install the weight corresponding weight on the weight shaft above the pressure plate (the instrument is equipped with 1500, 1000, 500, 250, 100, 50g standard weights each), so that it applies a certain pressure
to the specimen friction.
The pressure value
to be applied is selected according to the weight of the area specimen.
