Test Principle:
Composite Salt Spray Test Machine is composed of the cyclic corrosion test of the spray process, the damp and heat process, and the standing and drying process. The following are the schematic diagrams of these three processes:
1. Spray process
The system consists of salt water tank, pneumatic system, salt water storage tank, spray tower, nozzle, etc. The salt solution flows from the outside to the test chamber by using the natural drop, and the salt solution is atomized by compressed air through the spray nozzle.
Figure 1 Schematic diagram of the spray process
2. Damp heat test
The damp heat test system is composed of steam generator, blast, water circuit, condensation device, etc. After the salt spray test, the machine will set up a defogging program to discharge the salt spray out of the test room as soon as possible; Then the water evaporator will output the appropriate temperature and humidity according to the temperature and humidity set by the controller. Generally speaking, the humidity will be more accurately calibrated and constant after the temperature is stable. The temperature and humidity parameters of the damp heat test are as follows: Temperature: 30℃—60℃; humidity: 80%RH—98%RH.
Figure 2 Schematic diagram of damp heat test
3. Drying process
Standing and drying system adds drying blower, heating wire, air filter and other devices on the basis of damp heat system, if need to simulate standard atmospheric pressure environment test (temperature 23℃±2℃, humidity 45%~55% RH). Firstly, quickly remove the damp and heat test environment in the previous section by setting a defogging program to create a relatively clean test environment, and then the humidifier or dehumidification system works in coordination under the controller to produce an environment that meets the test requirements. The temperature and humidity parameters of the drying test are as follows: temperature: 20℃-60℃; humidity: 30%~60%RH (corresponding to the appropriate temperature point).
