Description
Summary:
DIN Type Abrasion Tester is to measure the abrasion resistance of rubbers (vulcanized thermoset rubbers and thermoplastic elastomers) that are subject to abrasive/frictional wear in their actual service, such as tires, conveyor drive belts, and shoe soles
Main Technical Parameters:
| Item | Specification |
| Specimens size | 16mm, 6-15mm (D) |
| Fixture load | 2.5N |
| Weight load | 2.5N,5N |
| Fixture lateral displacement | 4.2mm/wheel each lap |
| Wheel diameter | 150mm |
| Wheel length | 460mm |
| Wheel rotate speed | 40rpm |
| Abrasion speed | 0.32m/sec |
| Dip angle | 3°the angle of the specimen back shaft with vertical roller face |
Principle:
Under specified touched pressure and given area, when the sample and the abrasive paper get an angle, test the abrasion resistance of the sample on the abrasive paper with certain rank.
Wrap the abrasive paper on the roller. The sample adpress on the roller with abrasive paper to make the sample move horizontally along with the roller. Abrasion is produced on the one end of the cylinder sample. Measure the loss value of the sample and calculate the abrasion resistance according to sample density.
Design standard:
DIN-53516, ISO/DIS-4649, BS903 PART9 and GB-9867.
