The ozone aging box is divided into dynamic and static. The main difference between the two is that the sample holder is different. Let me explain it to you in detail below! The static ozone aging tank is fixed at both ends of the specimen with a clamp under the required elongation. When contacting the ozonated air, the length direction of the specimen is substantially parallel to the direction of the gas flow. The rotation speed of the sample holder is between (20 and 25) mm/s. In a plane perpendicular to the airflow, each sample continuously moves along the same path, and the time of one rotation of the same sample is (8~). 12) min. The dynamic ozone aging chamber is an exposure test in which the elongation of the sample is zero to the maximum elongation between successive cycles of stretching. There are two test methods for this method: 1 Let the sample be cyclically stretched from zero to the maximum elongation. It is recommended that the maximum elongation of the sample is 10% and the exposure time is 72H. 2 intermittent dynamic tensile test, the test method is to first stretch the sample to zero to the maximum elongation between reciprocating stretching, after a certain time, the sample is fixed at the maximum elongation, and then in the static pull Continue to expose in the same ozone-containing air. The test of alternating stretching of dynamic stretching and static stretching was periodically cycled as required by the tester.
