Hongda ozone aging test chamber can be used in rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheath, etc., under static stretching or continuous dynamic tensile deformation, or alternating between intermittent dynamic stretching and static stretching. Under deformation, exposed to a closed, unilluminated air containing constant ozone concentration and a constant temperature test chamber, the sample is tested for a predetermined time, and the degree of change in cracks or other properties occurring from the surface of the sample is evaluated to evaluate the rubber. Ozone aging resistance. Applicable to schools, factories, military, research, and other units. HEBEI PINGLE FLOUR MACHINERY GROUP CO., LTD , https://www.plrollermill.com
Hongda ozone aging test box is made of high-quality materials, processed and formed by the domestic advanced processing equipment, and the surface of the outer casing is sprayed, beautiful and flat. The colors are coordinated and the lines are smooth. The inner tank is designed to be a closed and non-direct light when working. It can be used to place the sample for the aging test. It can control the test temperature difference ±2 °C and use imported high quality mirror stainless steel plate. Indoor sample holders, fixtures and conduits are made of stainless steel and other materials that are not easily decomposed by ozone and affect ozone concentration. The sample holder can be rotated 360 degrees and the speed can be adjusted.
