Akron Machine Rubber Vulcanized Determination of Abrasion Resistance
Summary:
Rubber Akron abrasion testing machine is used to determine the wear resistance of sulfide rubber. It determines the wear volume of the sample within a certain mileage through the friction between the sample and the grinding wheel under a certain tilt Angle and a certain load.In line with the requirements of GB / T 1689 " wear resistance of sulfuric rubber and other standards. Digital setting, display wear times, automatic shutdown, the host and electrical control design as one, the use of calibration grinding wheel, beautiful shape, easy to operate.
Main techanical specifications:
1. The applied force of the rubber wheel | 26.7N(2.7Kgf) |
2. The rubber wheel shaft rotation speed | 76±2r/min |
3. The grinding wheel shaft rotation speed | 33-35r/min |
4. The Angle between the wheel shaft and the wheel axis | 0°-45° |
5. The power supply voltage | AC220V±10% |
6. Overall dimensions (length, width and height) | 600mm×480mm×400mm |
7. Net weight | 60Kg |
8. Sand wheel specifications | The abrasive is alumina, particle size 36mm,the adhesive is clay with medium hardness of 2 and size of 150mm 32mm 25 mm. |
Test sample standard:
The sample shall comply with the requirements of GB 1689, Determination of wear resistance of vulcanized rubber (with a clone grinding machine).
The sample is a strip of length (D+2h)*3.14+0~5mm, 12.7±0.2mm wide and 3.2±0.2mm thick.
Note: D is the diameter of the rubber wheel, and h is the sample thickness.
Its surface should be flat, and there should not be any cracks, impurities, etc.
Note: D is the diameter of the rubber wheel, and h is the sample thickness. Both sides of the sample are glued to the rubber wheel, but should not be strained when bonding. The diameter of rubber wheel is about 68mm, the thickness is 12.7±0.2ram, the hardness is 75~80 degrees (Shore A).
The diameter of the center hole shall meet the diameter of the rubber wheel shaft.
