Evaluating Material Resistance Using the Sulfur Dioxide Corrosion Chamber

Introduction
The sulfur dioxide corrosion chamber is a critical piece of equipment in the environmental testing domain. It assesses the resistance of materials and their protective coatings against sulfur dioxide (SO₂)-induced corrosion. This method is particularly important for industries such as automotive, electronics, construction, and coatings manufacturing, where components are exposed to corrosive environments. Among leading solutions, the LISUN SQ-010 Sulfur Dioxide Test Chamber stands out for its precision and adherence to international testing standards, such as ISO 6988 and GB/T 2423.33.

This article explores the functionality, applications, and technical aspects of sulfur dioxide corrosion chambers, emphasizing the LISUN SQ-010 Sulfur Dioxide Test Chamber. It also includes tables and data to highlight its performance and benefits.

Principles of Sulfur Dioxide Corrosion Testing
Sulfur dioxide corrosion testing simulates the chemical interactions that occur when materials are exposed to sulfur dioxide in controlled temperature and humidity conditions. The process typically involves:

• Preparation of the Specimen: Materials or coatings are cleaned and placed in the test chamber.
• SO₂ Exposure: A controlled amount of sulfur dioxide gas is introduced into the chamber.
• Temperature and Humidity Control: The environment is maintained at specific temperature and humidity levels to accelerate corrosion.
• Evaluation: After exposure, the specimen is analyzed for signs of degradation, including pitting, discoloration, or loss of protective coatings.
