1. Product Name and Purpose

2. Product Features

• Robust and Sealed Chamber Construction
  • The ozone aging test chamber is constructed with a heavy-duty stainless steel frame and walls. The stainless steel material is chosen for its excellent resistance to corrosion, which is essential as ozone can be highly reactive. The chamber is carefully sealed to prevent any leakage of ozone, ensuring a consistent and controlled test environment. The door is equipped with a reliable gasket and a secure locking mechanism to maintain the integrity of the enclosure. The interior of the chamber is designed to be smooth and easy to clean, minimizing the potential for any contaminants to affect the test results.
• Precision Ozone Generation and Concentration Control System
  • The chamber features an advanced ozone generation system. It can produce ozone with a high degree of accuracy and stability. The concentration of ozone can be precisely controlled within a wide range, typically from 10 parts per million (ppm) to 1000 ppm. The system utilizes state-of-the-art ozone generators and sensors. The sensors continuously monitor the ozone concentration inside the chamber and provide real-time feedback to the control unit. The control unit then adjusts the ozone generation rate to maintain the desired concentration level. This level of precision allows for highly accurate and repeatable tests.
• Accurate Temperature and Humidity Control
  • In addition to ozone concentration, the chamber also offers precise temperature and humidity control. The temperature can be maintained within a range of -20°C to +80°C, with an accuracy of ±0.5°C. The humidity control range extends from 20% to 95% relative humidity, with an accuracy of ±3% RH. Temperature and humidity play important roles in the ozone aging process, as they can affect the rate of chemical reactions. The chamber's control system ensures that these environmental factors are kept constant and within the specified tolerances, providing a more realistic simulation of real-world conditions.
• Intuitive Control Panel and Data Acquisition System
  • The equipment is equipped with an intuitive control panel that allows operators to easily set and adjust the test parameters, including ozone concentration, temperature, humidity, and test duration. The control panel also provides real-time displays of the current values of these parameters, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system. It records all relevant test data, such as ozone concentration profiles, temperature and humidity histories, and any changes in the physical properties of the test samples. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats, facilitating easy documentation and sharing of results.
• Sample Fixturing and Placement Options
  • The chamber is designed to accommodate a variety of sample sizes and shapes. It can be equipped with adjustable racks, trays, and holders to ensure proper positioning and exposure of the test samples. The sample fixtures are made of materials that are resistant to ozone and do not contaminate the test environment. This flexibility allows for the testing of different products, from small rubber components to large fabric swatches or plastic panels.

3. Specific Parameters

• Ozone Concentration Range and Accuracy
  • As mentioned, the ozone concentration can be adjusted from 10 ppm to 1000 ppm, with an accuracy of ±5% of the set value. This wide range enables the testing of materials that may be exposed to different levels of ozone in their intended applications. For example, automotive rubber seals may need to withstand relatively low levels of ozone, while some industrial rubber hoses may face higher concentrations. The accurate control of ozone concentration ensures that the test results are reliable and comparable.
• Temperature Range and Rate of Change
  • The temperature range of -20°C to +80°C allows for the simulation of a diverse range of climatic conditions. The rate of temperature change can be adjusted up to 5°C per minute. This rapid temperature change capability is useful for testing the thermal stability of materials in combination with ozone exposure. For instance, in the automotive industry, components may experience sudden temperature changes while being exposed to ozone in the atmosphere.
• Humidity Range and Rate of Change
  • The humidity range of 20% to 95% RH, with a rate of change of up to 10% RH per minute, provides a comprehensive assessment of the effect of moisture on ozone aging. High humidity can accelerate the degradation of some materials, while low humidity may have a different impact. The ability to control humidity precisely helps in understanding the complex interactions between ozone, temperature, and humidity.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, with options ranging from 0.5 m³ to 10 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 500 kg. This allows for the testing of a significant number of samples or larger and heavier products. For example, in the textile industry, large rolls of fabric can be tested to evaluate their ozone resistance.
• Test Duration and Cycling Capability
  • The chamber can conduct tests for extended periods, ranging from a few hours to several thousand hours. It also has the ability to perform cycling tests, where the ozone concentration, temperature, and humidity can be varied in a programmed sequence. This cycling capability mimics the fluctuating environmental conditions that products may encounter in real life, providing a more accurate assessment of their durability.
