Condensation and Corrosion, Surface Treatment

Condensation and Corrosion, Surface Treatment

Humidity control is critical in environments where anti-corrosion paint application is essential, particularly in industries like marine and others with exposed metal parts.

These environments require meticulous preparation of metal surfaces through sandblasting prior to painting. However, high humidity levels pose a significant challenge as they can lead to immediate corrosion and oxidation after surface preparation.

1. Corrosion Risk Post-Surface Preparation

High humidity levels post-surface preparation, especially after sandblasting, increase the risk of corrosion and oxidation, compromising the effectiveness of anti-corrosion coatings.

2. Inadequacy of Traditional Methods

Traditional methods such as heating the air are insufficient as they only reduce relative humidity without effectively removing moisture, leaving metal surfaces vulnerable to corrosion.
