application

Compared with traditional salt spray chambers, composite salt spray test chambers, alternating salt spray test chambers, and salt spray testing machines have more practical effects on products due to cyclic corrosion such as salt spray, drying, and wet heat. As products are transported, stored, and used in dry and wet environments, accelerated corrosion testing machines should be able to simulate these environments more realistically. Moreover, foreign research has also shown that cyclic corrosion is very similar to outdoor corrosion in terms of corrosion rate, structure, and morphology, and has excellent correlation with outdoor corrosion, and is included in the commonly used testing category. More and more tests in the automotive industry require multi-step aggregation of salt spray, drying, and wet heat combined for cycling.

Experimental conditions

● According to GB, ISO, IEC, ASTM, DIN, JIS standards, spray test conditions can be set:

1. Salt water spray test: NSS, ACSS

Laboratory: 35 ℃± 1 ℃, saturated air tank: 47 ℃± 1 ℃.

2. Corrosion resistance test: CASS

Laboratory: 50 ℃± 1 ℃, saturated air tank: 63 ℃± 1 ℃.

● Hot air drying test

1. Test temperature range: Room temperature+10 ℃~70 ℃± 1 ℃.

2. Test humidity range: less than 30% RH.

3. Using a blower, the air inside the external temperature box of the laboratory is heated by an air heater before entering the laboratory, creating a low humidity condition inside the laboratory. The temperature of the laboratory is controlled by the heater inside the temperature box. (SSR driver)

● Damp heat test

1. Test temperature range: Room temperature+10 ℃~60 ℃± 1 ℃.

2. Test humidity range: adjustable from 60% RH to 98% RH.

3. Using steam introduction method, water is heated to generate steam, which is then introduced into the laboratory through a blower. The microcomputer processor of the IPC-1000 controller, which plays the main control role, performs micro control when the humidity reaches the required value. When the humidity exceeds the value, dry hot air is introduced to dilute the moisture and discharge the excess moisture outside the test room. Electronic parallel micro humidification system.
