Ozone aging chambers are widely used in the testing of rubber products such as vulcanized rubber, thermoplastic rubber, and cable insulation sheaths. These devices simulate environmental conditions by exposing samples to a controlled atmosphere with a constant ozone concentration and temperature. The samples are subjected to static tensile deformation within an airtight chamber, and the test evaluates their resistance to cracking or other forms of degradation based on surface changes. This helps determine the long-term durability and performance of the materials under ozone exposure.
When operating the ozone aging chamber, it is important to follow several key safety and operational guidelines:
1. Ensure that the power supply includes an overload protection fuse specifically for this equipment. A proper grounding system must be in place to protect both the operator and the device from electrical hazards, which also extends the lifespan of the equipment.
2. Before starting the test, number each sample individually and place them on the test carousel. Make sure they do not touch or collide with each other, so that the ozone concentration remains consistent across all samples during the test.
3. After placing the samples, close the chamber door and turn off all control switches. Plug the power cord into the power source and turn on the system. The control panel’s power indicator should light up. If heating is required, activate the appropriate temperature switches (high or low) and adjust the automatic control settings accordingly.
4. The ozone aging chamber should be installed in a well-ventilated area, placed horizontally, and kept away from any flammable or explosive materials to ensure safe operation.
5. In certain cases, a blade switch may be installed in the power line for added safety. Always check the electrical performance of the unit before use, and make sure there are no open circuits or leaks. Note that the chamber does not have an explosion-proof feature, so flammable or explosive items must never be placed inside.
6. Avoid overloading the chamber with too many samples. Leave enough space to allow proper air circulation, which is essential for maintaining uniform temperature and ozone distribution throughout the test.
By following these guidelines, you can ensure accurate and reliable results while maintaining a safe working environment.
