rb(, , ); n-: Microsoft Yahei, r, Song Dynasty, nr; ; n-: .;"> Ozone test is suitable for testing the ozone resistance of rubber products, non-metallic materials, organic materials (such as coatings, paints, rubber, plastics, and their products) Aging performance and aging cracking test. Products such as vulcanized rubber, thermoplastic rubber, cable insulation sheaths, etc., are subjected to static stretching or continuous dynamic stretching deformation, or under alternating deformation of intermittent dynamic stretching and static stretching. The rubber is exposed to a closed, light-free test chamber containing a constant ozone concentration and constant temperature, and the sample is tested at a predetermined time to evaluate the ozone aging resistance of the rubber based on the degree of cracks or other changes in properties on the surface of the sample.

If there are cracks, please report To determine the degree of cracking, you can use the cracks that appear to explain the cracking situation or take pictures of cracked samples to illustrate. Under specified tensile conditions, the time required for the first drop of crack to appear is used to evaluate the ozone resistance of the sample. Determine the critical strain range for the maximum strain without cracking and the minimum strain for cracking after the specified exposure time.
rb(, , ); n-: Microsoft Yahei, r, Songti , nr; ; n-: .;"> After the test, the results are judged by the crack grade (that is, the depth and number of crack changes on the surface of the sample after aging for a specified time are evaluated). The crack grade can be divided into - grade , refer to B-"Rubber Atmospheric Aging Test Method", that is, grade no cracks; grade slight cracks; grade significant cracks; grade severe cracks; grade critical cracks.
