The low content of ozone in the atmosphere is the main factor causing rubber cracking. The ozone aging chamber simulates and strengthens the ozone conditions in the atmosphere, studies the effect of ozone on rubber, and quickly identifies and evaluates the anti ozone aging performance of rubber and the protective effect of anti ozone agents. Effective anti-aging measures are then taken to improve the service life of rubber products.

Set a transparent window at a reasonable position on the box door to observe changes in the indoor sample. The observation window adopts a multi-layer designemptyTempered glassGlass, inner laminated sheetguideElectric filmIt has the advantages of transparency, heat insulation, and is not prone to steam frosting

The equipment uses a long axis fan motor for stirring and a stainless steel multi blade impeller that is resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation, ensuring uniform and stable temperature in the laboratory

Using non reactive door handles makes operation easier

High quality fixed PU movable wheels are installed at the bottom of the machine, which can easily move the machine to the designated position and then fix the casters

1. By shell, electronic componentsOzone generatorThese major components make up

2. Fix the two ends of the specimen with a fixture under the required elongation, andOzone oxidationWhen in contact with air, the length direction of the sample should be basically parallel to the direction of the airflow

3. The fixture should be made of materials that are not easily decomposed by ozone, such as aluminum.

4. Rotate the sample at a speed between (20 ^ -25) mm/s in a vertical directionDry airflowWithin the plane, each specimen moves continuously along the same path

5. The time for the same sample to rotate once is (8 ^ -12) minutes. The scanning area of the sample (shaded area in Figure 2) * is less than that of the test chamberEffective area40% of it

6Sample preparationIt should comply with the provisions of GB/T 9865.1. The sample can be cut from the newly molded test piece, and if necessary, it can be cut from the finished product. The sample should at least

7. At least 3 specimens shall be used for each experimental condition.

8. The width of the long standard specimen shall not be less than 10mm, and the thickness shall be 2.0mm ± 0.2mm. The length of the specimen between the two ends of the fixture before stretching shall not be less than 40mm

1Variable speed motorDrive the sample holder device (meeting the static method)Tensile testThe running trajectory of the specimen conforms to the principle of cycloid trajectory.

2Ozone concentrationAutomatic digital display controller.

3. Dual beam "QUA" nondispersionUV ozone detector.

4. Digital display automatic online measurement.

5. Leave a calibration interface for metrological verification.

6. Ozone concentration/temperature and humidity setting value control PID self-tuning, easy and reliable operation.
