Ozone testing machine is to simulate and strengthen the atmospheric ozone conditions, the study of the role of ozone on the law of rubber, rapid identification and evaluation of rubber ozone aging resistance and ozone agent protection effectiveness of the method, and then take effective anti-aging measures to improve the service life of the rubber products, the shell of the equipment is mainly from the cold plate plastic spray molding, the inner liner is the selection of stainless steel material; for its test stand
What are the requirements of the equipment?
Equipment by the shell, electronic components, ozone generator, which consists of several major components; in the required length of the fixture to fix the ends of the specimen, and ozonation air contact, the length of the specimen should be basically parallel to the direction of the air flow; fixture materials must be ozone is not easy to decompose, such as aluminum.
The rotational speed of the specimen is between (20^-25)mm/s, and each specimen continuously moves along the same path in the plane of a vertical dry airflow; the time for the same specimen to rotate for one week is (8^-12)min. the scanning area of the specimen is at least 40% of the effective area of the test chamber; the specimen preparation should be in accordance with the provisions of GB/T9865.1; the specimen must be pressed out from a new mold. Must be cut from the new mold pressing out of the test piece, if necessary, can be cut from the finished product; each test conditions at least 3 specimens; long standard specimen width of not less than 10mm, thickness of 2.Omm 0.2mm, the length of the specimen between the two ends of the fixture before stretching is not less than 40mm.
Test rack requirements are so high, of course, the sample is placed is also need to focus on a very important factor. An important factor, because the placement of the sample may affect the results of the experiment, so that the results are biased, inaccurate; therefore, in the test with the ozone testing machine, we need to pay special attention to, so as to make the test results more accurate.
