Product features

The ozone aging test chamber is composed of ozone gas generated by a silent and efficient ozone generator, mixed with a certain amount of treated air in a heat exchanger, and sent to the test chamber. The ultraviolet detector continuously detects the ozone concentration online and feeds it back to the ozone generator control system. The control system effectively controls the occurrence of ozone based on the set value, so that the test chamber maintains the set ozone concentration. The heating and humidification system also operates, Meet all test conditions. The key components of this equipment are all imported original parts with international advanced level. The equipment has good operability, maintenance, temperature stability and durability, good safety performance, does not pollute the environment or harm personal health.

Working principle

Expose the vulcanized rubber sample to a closed and non illuminated air with a constant ozone concentration and a constant temperature test chamber under continuous rotation. Test the sample according to the predetermined time, and evaluate the rubber's ability to resist odor and oxygen aging by observing the cracking and other performance changes on the surface of the sample.
