The ozone aging test chamber is suitable for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation jacket and other products, under static stretching or continuous dynamic tensile deformation, or under intermittent dynamic stretching and static stretching alternate deformation, Expose to airtight and constant temperature test chamber with constant ozone concentration, test the sample at a predetermined time, and the degree of cracking or other performance changes from the surface of the sample to evaluate the resistance of the rubber to ozone aging performance. The standard of the static tensile test of the ozone aging test chamber stipulates that the specimen is clamped on a special fixture at both ends, and an elongation tensile is selected, generally 20%, the fixture is installed on a rotating sample rack, and the sample rack speed is (20 -25) mm / S, the temperature is (40 ± 2) ℃, the relative humidity is not greater than 65%, the test is conducted under the specified ozone concentration. Check the sample for cracks after a specified period of time. General ozone concentration selection (50 ± 5) × 10-8. The dynamic tensile test standard of the ozone aging test chamber stipulates that the sample holder can be automatically stretched to stretch and reset the sample, the stretching frequency is 0.5 ± 0.025Hz, the two ends of the sample are clamped on the special fixture, so that the sample is extended The elongation rate is cyclically stretched from 0 to the maximum elongation. The fixture is installed on the rotating sample holder. The rotation speed of the sample holder is between (20-25) mm / S at a temperature of (40 ± 2) ° C. Humidity is not more than 65%, under the specified ozone concentration, the fixture is cyclically stretched and reset and rotated with the sample holder for testing. Check the sample for cracks after a specified period of time. General ozone concentration selection (50 ± 5) × 10-8. Dynamic tensile testing is divided into continuous dynamic stretching and intermittent dynamic stretching.
