Ozone aging test chamber is a kind of test equipment widely used in various industries. The manufacturer will conduct reasonable research and analysis on the overall operation steps and problems in the simulation test according to different test boxes. This is a technology that accelerates the aging of rubber by simulating a high-intensity ozone environment. According to the sensitivity of rubber and some plastics to ozone, the aging resistance of rubber products is tested. The following is a brief introduction to the operation method in the box.
The Ozone aging test chamber generally adopts a cyclic working mode, that is, put the sample into the test chamber, make the sample reach a certain temperature and humidity conditions by heating and humidifying, and then fill the test chamber with a certain concentration of ozone gas to start The ozone generator reacts the ozone gas with the sample, simulating the ozone aging process in the natural environment.
Generally speaking, the working mode of Ozone aging test chamber can be divided into the following steps:
1. Heating and humidification: put the sample into the test chamber, and make the sample reach a certain temperature and humidity conditions by heating and humidifying, which helps to accelerate the process of ozone aging.
2. Oxygenation: Fill the test chamber with a certain concentration of ozone gas. Generally speaking, the ozone concentration is between 50-500pphm.
3. Ozone reaction: Start the ozone generator to make the ozone gas react with the sample, simulating the ozone aging process in the natural environment. The reaction process of ozone on the surface of the sample generally lasts from tens of hours to hundreds of hours, and the specific time depends on the test requirements.
4. Ventilation: After the ozone reaction is completed, the ozone gas in the test chamber needs to be discharged, usually through ventilation. Ventilation time is generally 2-4 hours.
Note that after completing a complete set of test work, according to the specific use of the test process, the use method needs to be explained according to the standard test conditions. After installation, it is necessary to take out the sample and clean the Ozone aging test chamber. The above is the general working mode of the Ozone aging test chamber. In practical applications, some adjustments and optimizations are required according to specific test requirements.
