Function Introduction

Salt spray environment:

Continuous salt spray exposure is widely used to test the corrosion resistance of components and coatings. Applications include industry, maintenance, construction and ships coatings; Electroplating and paint coating; Aeronautical and military coatings, surface layers and components, electrical and electronic systems and components.
Most of these tests, in accordance with special specifications, are widely used in related corrosion tests and are generally operated at higher temperatures.
Excluding drying cycles. It is required that the sprayed air should be heated before entering the nozzle.
During the salt spray function of this test chamber, it is like a typical conventional salt spray operation.The air jet solenoid valve is opened, and the compressed air is humidified through the saturator (humidity helps to keep the PH concentration stable) and then reaches

Nozzle.
The brine corrosion solvent from the brine tank is sucked to the nozzle, where it is mixed with compressed air.
The nozzle sprays brine solvent and air into corrosive mist.
The box heater maintains the programmed box temperature.
This function is also used for pure water mist exposure.

Dry environment
During the drying function, the dehumidification system is opened to discharge the moisture in the box out of the box, while the fan works to make the indoor air
Go to the air heater and then enter the box, thus creating low humidity conditions in the box. The temperature of the box is added by the box heater and air
Heater control. The air heater is turned off for 5 seconds before the drying procedure is completed, so that there is no drum in the vicinity of the heater passage and components.
The fan is turned off and overheated.

Humidity environment
During the humidity function, the hot water in the humidification tank boiler is evaporated into the box to maintain the set humidity of the box.

Condensed water environment:
During the condensation process, the water in the water tank is heated through the water tank heating pipe at the bottom of the tank, so that the tank body is kept at a relative humidity of about 100%.
