Traditionally, erosion detection is called salt water testing machine, salt water sprayer instrument, erosion embrittlement or salt spray test chamber
.
Typical salt spray test chamber erosion test standard: put the specimen into a stable, saturated state of air humidity (RH) natural environment, and in the necessary time, such as 999H, with 5% NaCI aqueous solution as a solidification corrosion resistance, its temperature of 35 ~ 40s °C; In addition the way is called the air humidity method
.
This is done with water that does not contain salt or any other compound, and is often considered an environmental humidity test standard
.
Initially, the purpose of the salt spray chamber was to certify the length of life of the erosion by sorting the various levels of erosion or by simply classifying the test as passing or failing
.
As everyone knows, in reality, no one really places the commodity in the natural environment standard of 20% salt water, 35 ~ 40s °C, RH air humidity, although there are still many laboratories that still use this method, but its problem is that it is impossible to distinguish
the linkage between the service life of the product and the service or the final application of the zui.
