Salt dry wet corrosion test chamber
The test cycle of salt dry and wet corrosion test chamber is composed of four spray cycles, each spray cycle is followed by a humid and hot storage cycle, the test is conducted after spray and wet storage, and the test is conducted under standard atmospheric conditions for a cycle. The humidity of spray is between 15 and 35 ℃, and the humid and hot storage conditions are: the relative humidity is 40 ℃ ± 2 ℃; The standard atmospheric pressure used for the experiment is; The temperature is 23 ℃± 2 ℃, and the relative humidity is 45% to 55%.
Based on the above tests to assess the salt spray corrosion resistance of materials and their protective layers, as well as to compare the process quality of similar protective layers, this equipment is widely used in enterprises and institutions such as aerospace, automotive and motorcycle, electrical and electronic, chemical and metallurgical, quality inspection and measurement, postal and telecommunications, shipbuilding and railway, as well as universities, colleges and research institutions.

The salt dry wet corrosion test chamber is used to accelerate the corrosion of materials or products, testing the degree of damage suffered by materials or products within a certain time range. And by using salt solution or acidic salt containing solution in a test chamber without moving the test sample, four cyclic test effects can be achieved: salt spray, drying, relative humidity, and low-temperature storage.
