Roller abrasion testing machine, rubbter testing instrument
Overview
The machine is mainly composed of a power system, a rotating cylinder, a sample clamp, an automatic stop system, and a rack and small transmission gear device for the rotation of the sample, a base and a dust collector. The main principle is: under a certain load, on a certain level of gauze, the column sample is cross-cut on the surface of the gauze for a certain stroke, by measuring the mass wear of the sample, and then calculating the density of the sample. Volume wear. In order to make the test comparable, it is necessary to use standard rubber, and the test results are expressed as the relative volumetric grinding based on the verified gauze or the wear resistance base expressed as the abrasion amount relative to a certain standard rubber. Compliant with GB9867-1988 "Determination of wear resistance of vulcanized rubber (Rotary Roller Abrasion Machine Method)", DIN ISO 4649-2006 vulcanized or thermoplastic rubber roller method for wear resistance and DIN--53516-1987 raw rubber and elastomer Inspection. Wear test.
