A Deep Dive into Mixed Flowing Gas Chamber Technology

In the realm of environmental testing, the mixed flowing gas chamber has emerged as a crucial technology for simulating corrosive environments and testing the durability of materials and electronic components.In this blog, we explore the key technologies behind mixed flowing gas chambers.

Gas Mixing and Flow Control Technology

One of the core aspects of a mixed flowing gas (MFG) chamber is its gas mixing and flow control system. The ability to create a precisely controlled atmosphere is vital for replicating real-world environments where products are exposed to corrosive gases.

Modern control technology ensures that the gas mixture remains stable and consistent throughout the test. This is achieved by using precision mass flow controllers (MFCs) and gas analyzers that continuously monitor and adjust gas ratios. For instance, sulfur dioxide (SO₂) concentrations are typically set between 10-30 ppm, nitrogen dioxide (NO₂) between 1-15 ppm, chlorine (Cl₂) at 1-5 ppm, and hydrogen sulfide (H₂S) at 0.1-2 ppm, depending on the test requirements. Gas flow rates are often adjusted to 10-100 L/min to ensure even distribution inside the chamber. The system continuously monitors and maintains gas concentrations within ±2% of the target values, guaranteeing stable test conditions.

Temperature and Humidity Control Technology

Temperature and humidity are critical variables in environmental testing. Mixed flowing gas chambers are designed to control these factors with high precision, replicating the natural fluctuations that materials may encounter in various environments. Effective temperature and humidity management ensure that the corrosion process is accelerated, providing valuable insights into how materials will perform over time.

Advanced temperature control systems in these chambers use a combination of heating, cooling, and insulation technologies to maintain stable conditions. Temperature ranges typically vary from -40°C to +85°C, allowing for the simulation of extreme environmental conditions. The chamber can precisely adjust the temperature within ±1°C to ensure accurate test results. Humidity control, on the other hand, often involves sophisticated humidification and dehumidification systems. These systems can maintain relative humidity (RH) levels from 30% to 98%, depending on the test specifications, with accuracy within ±3%.

Corrosion Acceleration Technology

A key advantage of mixed flowing gas chambers is their ability to accelerate the corrosion process. Time is often a limiting factor in material testing, and manufacturers need results quickly to make informed decisions. By using mixed flowing gases in a controlled environment, mixed flowing gas chambers can simulate years of natural corrosion in just a few days or weeks.

The accelerated corrosion process in these chambers involves the combination of corrosive gases, specific humidity levels, and temperatures that mimic real-world conditions. This allows manufacturers to observe the degradation of materials or components under conditions they would face in the field. The ability to simulate such extreme environments makes mixed flowing gas chambers an invaluable tool for industries such as automotive, aerospace, and electronics, where product reliability is paramount.

Monitoring and Data Acquisition Technology

Accurate monitoring and data acquisition are vital for tracking the progress of tests and analyzing the results. Mixed flowing gas chambers are equipped with advanced sensors and data logging systems that continuously monitor environmental conditions within the chamber. This includes real-time tracking of gas concentrations, temperature, humidity, and other critical variables.

The data collected during testing is crucial for understanding how materials respond to corrosive environments over time. Modern chambers often feature automated systems that allow for remote monitoring and control, giving operators the flexibility to adjust test parameters or review data without being physically present. LIB's mixed flowing gas chambers include an intuitive data acquisition system that not only records essential data but also provides detailed reports for post-test analysis.
