TABER Wear-resistant operation test 1. Use operation test is suitable for leather, cloth, coating, paper, floor tile, flat plate, glass, natural rubber, etc. to wear-resistant test, the method is used to cut the test piece with a standard cutting wheel. And the load must be worn by weight, to take out the test piece after the specified number of revolutions, observe the status of the test piece or the weight difference between the test piece before the test piece test. Wear index calculation formula: wear loss weight / test Return number × 1000 supplied to the grinding wheel number: H-18, H-22, CS-10, CS-17, CS-32, CS-33 3, Technical Specifications Rotation Speed: 30-75R / min adjustable ( Digital display surface diameter: 100mm sample table diameter: 113mm Roop number setting range: 1-999999 Weight: Balance weight, 250g, 500g, 750g, 1000g double wheel pressure range: 125g, 250g, 500g, 750g, 1000g, 1250g, etc., the height: adjustable shape: 220mm × 380mm × 300mm Weight: 20kg III, operation steps Prepare the instrument before the test, the instrument is connected to the power supply, the exhaust port is connected to the vacuum cleaner accessories and other instruments: standard A pair of grinding wheels, double-sided adhesive (hard), fine sandpaper (check). According to different standards, it is necessary to prepare 0.1mg precision balance, fabric strong machine, appearance evaluation light box, etc. to evaluate the test results. Sample: Cutting is about 110mm, and the holes are 8mm in the middle. If you need to compare the changes before and after the sample, you need to weigh the sample original weight (such as the sample is a fabric, etc., it is necessary to stick the standard double-sided adhesive to the outer stickers, weigh the total weight) If you need to compare the strong changes before and after the sample, you need to test its original strength before the test; other properties such as haze need to be tested before testing to determine the original parameters. The sample needs to be pre-adjusted for at least 8 h. Acceleration: After power-on, start the instrument in the arms raised state, and adjust the speed control knob to the required speed according to the digital display. V. Test Step 1, the mounting sample will be placed on the test stage in accordance with the standard requirements. Keep the sample flat, tighten the pressing nut and gasket, and fasten the sample fixation ring with hex wrench. 2, the folder grinding wheel and the weight will be mounted the pre-ground standard wear wheels to the inside of the balance arm and tighten the tension. The weight weight or balance weight according to the desired pressure pack. The wear wheel of the corresponding specifications is installed according to the wear wheel specification of different material tests in the corresponding standard. 3, start opening the power switch. Set the number of preset rings on the counter. Press the start button, the motor drives the turntable to start rotation. Note: 1. When the grinding wheel grinds the surface of the sticker or the surface of the grinding wheel, replacement is required. 2. Before testing a sample, you need to clean the grinding wheel with a brush. 6. After the sample results are evaluated to reserve the number of times, the instrument automatically stops or determines that the test end is to stop the test, turn off the vacuum cleaner. Take out the sample for evaluation. FQJ, read full text
