The small content of ozone in the atmosphere is the main factor of rubber cracking. The ozone aging chamber simulates and strengthens the ozone conditions in the atmosphere, studies the action law of ozone on rubber, quickly identifies and evaluates the methods of rubber anti-ozone aging performance and anti-ozone agent protection efficiency, and takes effective anti-aging measures to improve the service life of rubber products.
The ozone aging resistance test chamber is used to test the cracking resistance of rubber products in the ozone environment. The ozone resistance test machine can control and adjust the concentration of ozone environment to determine the ozone resistance of the test piece.
Conforming standards: JIS K 6259 ASTM1149 ASTM171 ISO1431 DIN53509 GB/T13642 GB 2951 (ozone resistance test method for wires and cables) and GB/T 7762-2014 (vulcanized rubber or thermoplastic rubber_ozone cracking resistance dynamic tensile test)
The ozone aging resistance test chamber is used to test the cracking resistance of rubber products under the ozone environment. The ozone resistance test machine can control and adjust the concentration of ozone environment to determine the ozone resistance of the test piece.
The length of the sample is basically parallel to the direction of the air flow when the sample is in contact with the ozonated air when the two ends of the sample are fixed on the rotating aluminum fixture under the specified elongation. Before the adjustable travel range of the sample is 0-40 mm, the sample rotates at a speed of (20~25) mm/s, so that each sample moves continuously along the same path in a plane perpendicular to the air flow. The time for the same sample to rotate for one cycle is (8~12) min, and the scanning area of the sample is about 40% of the effective area of the test chamber.
