DRK128C Martindale Abrasion Tester is used to measure the abrasion resistance of woven and knitted fabrics, and can also be applied to nonwovens. Not suitable for long pile fabrics. It can be used to determine the pilling performance of wool fabrics under slight pressure. Not suitable for wool fabrics with a thickness of more than 3mm. Applicable Standards: GB/T4802.2, GB/T21196.1～4, GB8690, ASTMD4966, ASTMD4970, ISO12945.2 Structural Features: 1. This machine is composed of two parts: the main body of the instrument and the electrical part, and it is a desktop structure. The metal component is the main body of the instrument, which carries out the test work through the electric control system. Its action is driven by a motor, and the grinding head is driven to move through a reducer, guide plate, etc. The trajectory of the grinding head is similar to the actual wear process of the fabric. 2. When the preset times are completed, the instrument will stop automatically. 3. The man-machine interface is simple and convenient to operate, and the display is intuitive. Main Specifications: 1. Number of friction heads: 9 2. Diameter of sample holder: Φ38mm and Φ90mm 3. Diameter of grinding table: Φ120mm 4. The total weight of the 38mm diameter sample holder and guide rod is: (198±2) g The total weight of the 90mm diameter sample holder, guide rod and O-shaped rubber ring is: (155±1) g The total weight of the 90mm diameter sample holder, guide rod, O-shaped rubber ring and loading block is: (415±2)g Heavy hammer: 395g±2g, 594g±2g The total mass of the loading block and specimen clamp assembly shall be: Large piece (795±7)g, that is, the nominal pressure applied to the sample is 12 kPa A small piece of (595 ± 7) g, that is, the nominal pressure applied to the sample is 9 kPa 5. Counting range: preset counting 1～990000 times 6. Test speed (rotating speed of grinding head): 47.5±2.5r.p.m Note: The standard configuration only comes with 47.5±2.5r.p.m, and the other 25r.p.m and 75r.p.m need to be optional. 7. Power supply: 220V±10%, 50Hz 8. Motor power: 120W 9. Dimensions: 850mm×600mm×400mm 10. Weight: instrument 120kg and 22kg accessory box
