Precautions for using ozone aging test chamber

With the development of the rubber industry, more and more attention is paid to product quality, and the ozone aging test chamber industry has developed rapidly. The ozone aging test chamber simulates and strengthens the ozone conditions in the atmosphere, studies the law of the effect of ozone on rubber, quickly identifies and evaluates the anti-ozone aging performance of rubber and the method of anti-ozonant protection, and then takes effective anti-aging measures to improve rubber The service life of the product. What are the precautions for using the ozone aging test chamber?

The precautions for using the ozone aging test chamber are as follows:

1. The sampling tube material of the ozone aging test chamber should be made of materials with strong oxidation resistance, such as glass, polytetrafluoroethylene, polyvinylidene fluoride; stainless steel materials should also be used as little as possible to reduce ozone loss in the sampling tube. The sampling tube should be as short as possible, generally not more than 2m when measuring low concentrations. Do not leak air from the sampling tube to the detection instrument, otherwise the measured value will be low.

2. The sampling tube of the ozone aging test box should be cleaned and dried regularly. A dirty sampling tube will make the measured value much lower. The ozone analyzer should be calibrated regularly to ensure reliable measurement data.

3. When the ozone aging test box detects lower concentration of ozone, the new PTFE tube must be fully "ozonized", that is, the inner wall of the sampling tube is stabilized by the gas containing higher concentration of ozone.

4. When the ozone concentration is found to be abnormal, the operation should be stopped, and then the power of the equipment should be turned off immediately, and the laboratory should be left immediately. At the same time, the manufacturer of the equipment is required to check the fault. In order to protect your personal safety and conduct tests well to meet your test requirements, please follow the precautions for operating the ozone aging test chamber above.
