The salt spray test is a test that artificially simulates the salt spray environment. Compared with the exposure test under atmospheric conditions, it has significant advantages: the corrosion environment can be controlled and the environment has good reproducibility; the test time is significantly shortened; , Financial and material resources. Its development and promotion are very fast, and it has developed from the initial simple neutral salt spray test to: acetate salt spray test, copper salt accelerated acetate salt spray test and alternating salt spray test.
The salt spray test chamber utilizes a salty solution or an acidic salty solution to accelerate the corrosion of materials or products under the environment of a certain temperature and relative humidity to reproduce the degree of damage suffered by the materials or products within a certain time range. The equipment can be used to evaluate the ability of materials and their protective layers to resist salt spray corrosion, and to compare the process quality of similar protective layers. It can also be used to evaluate the ability of some products to resist salt spray corrosion.
