GB/T 533 – 2008 Rubber Vulcanized or Thermoplastic - Determination of Density GB/T 9867 – 2008 Rubber Vulcanized or Thermoplastic - Determination of Abrasion Resistance Using a Rotating Cylindrical Drum Device 3 Apparatus and Materials 3.1 Abrasion machine Abrasion machine shall meet the requirements of 5.1 in GB/T 9867 - 2008 and adopt non-rotating holder. 3.2 Abrasive cloth Abrasive cloth shall meet the requirements of 5.2 in GB/T 9867-2008. 3.3 Balance The balance used for weighing the mass of sample shall be accurate to 1mg. 3.4 Standard glue Standard glue shall meet the requirements of B.2 in GB/T 9867 - 2008. 3.5 Rotating cutter The size of rotating cutter shall meet the requirements of 5.3 in GB/T 9867 - 2008. 3.6 Abrasion machine for top piece of leather shoes The grinding machine for top piece of leather shoes is as shown in Figure 1, which is used to cut the top piece of leather shoes into cylindrical sample. One side of the grinding machine is a grinding wheel (100 mm ~120 mm in diameter) driven by motor. The grinding wheel is white corundum, with the particle size of 60 meshes and linear speed of 15 m/s ~ 20 m/s. The other side is the holding device for top piece. Top piece sample is fixed in the holding device and can rotate with the motor of the holding device at the speed of 50 r/min~60 r/min. The distance between the grinding wheel and the holding device is adjustable, when the top piece sample gets close to the grinding wheel while rotating, the top piece will be ground by grinding wheel until it becomes a cylindrical sample with diameter of 16mm.
