Copper accelerated ozone aging test chamber

Product Description

Copper accelerated ozone aging test chamber Standard Features

1. The nature of the science: How does copper reconfigure the kinetics of ozone aging?

Copper is not a passive carrier in ozone aging tests, but rather accelerates material failure through a dual mechanism of catalyzed ozone decomposition and metal ion migration:

- 

Catalyzing ozone decomposition: The copper surface promotes the conversion of ozone (O) to reactive oxygen (O-), and free radicals attack the molecular chain of the material 3-5 times faster;

- 

Ion Migration Synergistic Corrosion: In humid environments, copper ions penetrate into material micro-cracks, triggering galvanic corrosion (e.g. rubber vulcanizing agent deactivation).

Equipment design challenges: traditional ozone chamber cannot simulate copper-catalyzed multiphase reactions, requiring reconstruction of the environmental simulation system.

2. Technological innovation: copper-ozone-hygrothermal multi-factor coupling system

2.1 Copper acceleration module design

- 

Copper exposure control unit:

Built-in adjustable copper mesh array (purity 99.9%), supports proportional programming of copper surface area to ozone concentration (0.1-5cm/L);

Copper surface passivation coating (optional) to simulate the catalytic effects of different oxidation states of copper (e.g. differential effects of CuO/CuO on rubber aging).

- 

Ion migration simulation:

Atomized copper salt solution (e.g. CuSO) injected into the system to achieve copper ion transport at the gas-liquid interface (in accordance with ASTM D4708 accelerated copper aging test).

2.2 Intelligent environmental coupling control

- 

Dynamic response algorithm:

Multi-dimensional parameters of ozone concentration (20-500pphm), copper ion concentration (0-100ppm), temperature and humidity (-20~90/10-95%RH) real-time coupling control;

AI-based prediction model to automatically match copper catalytic strength with material failure thresholds (e.g., critical O-concentration of tire sidewall rubber).

- 

Non-uniform field simulation:

Partitioned copper catalytic design to simulate gradient aging of materials at locally high catalytic intensities (e.g., automotive seals exposed differently in the engine compartment vs. outside).

Beyond Conventional: Why Copper Accelerated Ozone Chamber?

- 

More realistic acceleration of failure: Copper catalysis reduces aging time by 50-70% and increases the consistency of the failure mode with natural exposure;

- 

More accurate life prediction: multi-factor coupled data supports AI-driven reliability simulation (compliant with IEC 62506 accelerated test standard);

- 

Lower R&D costs: a single test can replace the traditional ozone + salt spray + metal corrosion multi-equipment tandem test.
