Free QuoteThe Compound Salt Spray Tester is also called the composite salt spray test chamber. It is the closest to the actual natural conditions in the accelerated corrosion test. Combined tests, such as salt spray, dry, humid, standing at room temperature, low temperature and other environments, can be combined in any order or individually.
The main test items are for products used under severe environmental changes, such as automobile and motorcycle parts, aviation equipment, photographic equipment, building materials, electro-coating coatings and electronic and electrical systems and other metal electrochemical corrosion resistance.
The composite salt spray tester is used to test the corrosion resistance of the products after the surfaces of various materials have been subjected to corrosion treatment such as electroplating, anodizing, spraying, and anti-rust oil.
The pressure air generated by the air compressor is filtered by the filter tank and then passes through the pressure regulating valve to reach the saturator, and then the initial nozzle of the saturator generates a moderately high but suitable temperature air temperature, and at the same time absorbs the saltwater in the spray tower. Come up to achieve the spray effect. The purpose of the air compressor is to make the water mist, and the function of the saturator is to keep the saltwater from crystallizing.

The temperature of the salt spray test chamber is required to be controllable, and the temperature of the inner chamber should be maintained at least between 23°C and 35°C. |
The salt spray system consists of a solvent tank, a pneumatic system, a water tank, a spray tower, a nozzle, etc. The solenoid valve moves the water from the storage tank to the test room, the heating pipe works to provide the required temperature in the tester, and the salt solution is compressed by spraying. Air atomization.
The spray tower is detachable and easy to remove and wash. In salt spray conditions, when the sink low level switch detects a low water level, the sink heater turns off and spraying stops. The water level indicator is automatically filled with water by turning on the water filling solenoid valve until the high water level switch detects the high water level. When the water injection solenoid valve stops, the heating tube starts to work. The spray will automatically start when the program requirements are met.
The drying system is composed of blower, air heater, pipeline, etc. Under the drying function, the indoor air is fed into the box by the blower through the air heater, thus creating a low-humidity environment in the tester. The temperature of the tester is determined by the humidifier and the humidifier. Air heater control. , The large air volume blower can also change the temperature very quickly, so as to realize the fast circulation function. At the same time, when the temperature reaches the requirement, if the humidity difference is large, the humidifier also outputs part of the power to compensate the humidity in the tester.
The humidity system is composed of steam generator, water circuit, condensing device, etc. Under the humidity function, by evaporating hot water into the tester, the tester body can maintain relative humidity. It can also maintain a proper temperature in the tester through the combination of the heater of the steam generator and the refrigeration of the compressor. When the temperature reaches the set requirements, if the humidity is too high, the condenser will reduce the humidity, on the contrary, if the humidity is too low, the humidifier will output part of the power to adjust the humidity in the tester.
