As an important means to simulate the corrosion resistance of materials, salt spray test performed by salt fog chamber is widely used in many industries. The corrosion resistance of the material is assessed by exposing the sample to an environment containing salt spray and observing the degree of corrosion on its surface. However, due to the complex testing environment of salt spray test, there will inevitably be some errors and deviations during the use of equipment.
The prolonged use of the salt spray test chamber may lead to wear or aging of some parts of the equipment, such as clogged spray heads, heating system failures, humidity sensor failures, etc.
The concentration of salt water directly affects the concentration of salt spray, and the concentration of salt spray is an important index to evaluate the corrosion. During the test, if the concentration of salt water is not uniform, the concentration of salt spray may be unevenly distributed, resulting in inconsistent test results.
The specific position of the sample placed in the salt spray test chamber will affect the deposition and corrosion effect of the salt spray. Different locations may receive different levels of salt spray, so the test results may be biased.
a. Regularly check and clean the equipment, especially the spray device and nozzle, to ensure that it is smooth. Calibrate and maintain the heating system and humidity sensor to ensure their normal operation.
LIB salt spray test chamber ：
The spray tower is adjustable in height and spray volume.
Quartz nozzles are easy to clean and resistant to high temperatures, corrosion, and clogging.
b. When preparing the brine solution, the concentration of 5% is strictly in accordance with the standard ratio to ensure the accuracy of the solution concentration. At the same time, during the storage process of brine solution, the solution is stirred regularly to maintain the uniformity of brine.
LIB salt spray test chamber ：
Built-in 30 liter salt solution tank with a brine mixing system to keep the brine even.
A salt water stirring system is installed in the salt water tank:stir the salt water,heat the salt water to stabilize the pH value.
c. Determine the location of the sample before the test, and ensure that each sample is in a uniform salt spray environment. In general, the sample should be suspended or placed at a distance from the spray nozzle to ensure an even distribution of the spray.
LIB salt spray test chamber ：
The number and location of spray towers will be designed according to the size of the workroom to ensure that the test samples can receive the salt spray evenly and ensure the accuracy of the test.
