Walk in Composite Salt Dry Wet Testing Machine 3m ³

Use:

1. The corrosion of protected and unprotected metal materials is affected by many environmental factors, which mainly depends on the type of metal material and the type of environment. It is impossible to design a laboratory accelerated corrosion test room that includes all environmental factors that affect corrosion resistance. Therefore, the laboratory test is designed to simulate the factors that play a major role in the corrosion of metal materials. This equipment is designed to simulate and increase the impact of the environment on metal materials exposed to outdoor atmospheres with salt pollution and accelerated corrosion. The equipment includes test methods for cyclically exposing specimens to salt spray, dry, and humid heat environments. This equipment test is a comparative test, and the test results cannot predict the long-term results of the corrosion resistance of the same metal material used under these environmental conditions. However, this method can still provide valuable information on the relevant performance of materials exposed to salt pollution environments similar to the test conditions. Compared with traditional accelerated corrosion tests such as neutral salt spray test (NSS), acetic acid salt spray test (AASS), and copper accelerated acetic acid salt spray test (CASS), the biggest advantage of this equipment test is that it can better reproduce the corrosion occurring in outdoor salt pollution environments.

2. The accelerated corrosion test of this equipment is applicable to: metals and their alloys, metal coatings (anodic and cathodic), conversion coatings, anodized coatings, organic coatings on metal materials, etc.
