Exploring the Benchtop Environmental Chamber: Applications and Benefits
Read More >
The core of the ozone aging test chamber lies in its ozone generation system and control system. During operation, the ozone generator inside the test chamber produces ozone through specific chemical reactions, creating a high-concentration ozone environment. Ozone is a strong oxidant that can quickly react with molecules on the surface of materials, thus simulating the aging process of materials due to oxidation in real environments.
The control system inside the ozone aging test chamber is responsible for precisely controlling parameters such as ozone concentration, temperature, and humidity to ensure consistency and repeatability of test conditions. These parameters can be adjusted according to different testing needs to simulate various environmental conditions, such as tropical, desert, and marine environments.
Automotive Industry
In the automotive industry, various rubber parts are used, such as door seals, wipers, shaft wheel covers, fuel hoses, tires, etc. In rubber parts, cracks often occur due to various environmental factors, especially ozone in the atmosphere, which can break carbon-carbon double bonds. For vehicles, the lifespan of rubber not only concerns quality but also safety, especially in the case of fuel lines or tire bursts.
Aerospace Industry
In the aircraft industry, the fatigue strength of rubber parts and rubber elastomers is a specific safety aspect. In the past, cracks in the insulation layer have led to cable fires, causing catastrophic airplane crashes. In space (space shuttles), fatigue strength is very important because repairs are extremely difficult. This also applies to the cables of maglev trains.
Tire Industry
Tires are a safety risk for any means of transport—cars, trains, elevators, airplanes, buses, trucks, bicycles, and race cars—if the material has cracks.
Semiconductor Industry
In recent years, the semiconductor industry has shown increasing interest in the application of ozone. The technology of using ozone to clean wafers has now been established, and ozone oxidation of organic and metal contaminants in water is also widely utilized.
Ozone Generation
The test chamber is equipped with an ozone generator that produces ozone gas through specific testing methods. Ozone is delivered into the test chamber through pipelines in the generator.
Control of Gas Flow
The ventilation system in the test chamber controls the flow of ozone to ensure that the set ozone concentration is reached and distributed evenly within the chamber. Airflow is usually achieved through fans or duct systems.
Control of Temperature and Humidity
The ozone aging test chamber is equipped with a heating system and humidity control system. The temperature and humidity of the test environment are controlled through components such as heaters, humidifiers, and sensors.
Ozone Concentration Control and Detection
During the test, the ozone concentration inside the chamber and the samples are periodically monitored and assessed, recording changes in the physical properties, chemical properties, and appearance of the samples.
Evaluation of Test Conclusions
Based on the test results and the original performance data of the samples, the aging condition of the samples is analyzed to assess the material's weather resistance.
