1.1. Application-Ozone aging test chamber  is mainly suitable for polymer materials and products (rubber) of the resistance to ozone aging performance test. Ozone content in the atmosphere is very low, but it is the main factors of polymer materials aging. Ozone aging test chamber simulating and strengthen the ozone condition in the atmosphere, get approximate to actual use or reproduction of the test results in a short time. The studay of ozone effect regulation to rubber products, quickly identify and evaluate rubber materials resistance to ozone and antiozonant protection efficiency method,and then take effective aging proof measures to improve the service life of rubber products.


1.2. Principles and methods-test methods can be divided into "static" and "dynamic" according to test methods and standards. Static means that the sample is stretched and placed in the test box for testing, while dynamic means that the sample is placed in the test box. On the fixture, do the test while stretching, and the fluctuation of the stretching is about 5%-45% of the tested sample itself

3.4. Requirements of the sample rack

a) (Dynamic experiment; optional)-Fix both ends of the sample with clamps under the required elongation. When in contact with ozonized air, the length of the sample should be basically parallel to the direction of airflow

b) The fixture should be made of a material (such as aluminum) that does not easily decompose ozone.

c) Make the sample rotation speed between (20^-25) mm/s, in a vertical dry air plane, each sample continuously moves along the same path

e) The sample preparation should meet the requirements of GB/T 9865.1. The sample is best cut from the newly molded test piece, if necessary, it can be cut from the finished product. The sample should be at least 3 samples per test condition. The width of the long standard sample is not less than 10mm, the thickness is 2.0mm±0.2mm, and the length of the sample between the two ends of the clamp before stretching is not less than 40mm.
