synthetic grass silk wear test methods

synthetic grass silk wear test methods

         1 Range of wood used in the method discussed in the laboratory or in the field, the wear resistance test wire grass.
         2 Principle specimen under the action against the grinding wheel wear caused, synthetic grass manufacturers measure the overall results in impaired mountain.
         3 Test Equipment
         A rotating platform, double abrasion machine;
         2-friction sheet on the new replacement wheel, 500g weight placed on each wheel;
         Three scales, weighing accuracy of ± 0.01g.
         4 samples
         Take three small length of 100 MU, width of at least 100 without the use of a sample of brain, a length of at least 100, a width of at least 100 samples have been used for testing.
         5 Test Procedure
         With the balance weight of the sample weighed out. The sample was placed in the abrasion machine with the corresponding bit in JIA, the lower the wheel, put the yellow on the sample, start the machine. Stop the machine rotates 1000 times to remove loose debris on the specimen, ffi new with the balance weight of the sample, said Hill. Repeat 5 times, by a total of 5000 times the sample rotation. Replaced after every 1000 rotating wheel on Friction film.
NOTE: See, smearing mountain wear performance, resulting in wheel becomes loaded, then the test is considered invalid. Before grinding wheel in the electric ones, this problem can shorten the time interval against the service. When the test sample is not used, use another W block repeat the test specimen.
         6 Test Results
         1 calculate and record the time of each rotation of 1000 to increase the amount of wear.
         2 without the use of the material. Species of bamboo flower count and record each sample under the 1000 rotation per the increased loss.
         Calculate and record the three samples five times successfully, rotation f 1000 for the loss of the child's arithmetic mean.
