Description
Corrosion of protected and unprotected metallic materials is influenced by many environmental factors, which mainly depend on the type of metallic material and the type of environment. It is impossible to design a laboratory accelerated corrosion test chamber that includes all environmental factors that affect corrosion resistance. Therefore, the laboratory test is designed by simulating the factors that play a major role in the corrosion of metallic materials. This equipment is designed to simulate and increase the effects of the environment on metallic materials exposed to an outdoor atmosphere that is contaminated with salt and can accelerate corrosion. The equipment includes a test method for cyclically exposing the sample to salt spray, dry, hot and humid environments. This equipment test is a comparative test, and the test results cannot predict the long-term results of the corrosion resistance of the same metal material used under this environmental condition. However, this method can still provide valuable information on the relative performance of materials exposed to salt pollution like the test conditions. Compared with traditional accelerated corrosion tests, such as neutral salt spray test (NSS), acetic acid salt spray test (AASS), and copper accelerated acetic acid salt spray test (CASS), the biggest advantage of this equipment test is that it can better Reproduces corrosion that occurs outdoors in salt-contaminated environments.
The equipment has temperature-humidity-heat alternating salt spray compound test chamber with temperature and humidity adjustment function is used to test various performance indicators and quality management of accessories under alternating compound conditions such as high temperature, humidity, dryness, and salt spray.
The equipment has an emergency braking function, and a brake switch is installed on the equipment. When an abnormal situation occurs, the equipment can be powered off through the control switch.
The equipment is equipped with corresponding system software, which can run stably on the provided operating system, and the software interface is in Chinese or English, the software includes temperature change test, humidity, precision calibration, and equipment self-test module.
The system software can record in real time, save automatically, and optimize data, and can draw temperature-time, humidity-time curves through software settings.
The system software is set with a safety protection parameter interface, and after the setting is completed, it will be given priority during the test process, thereby ensuring the safety of the test.
The system software can achieve the function of test data security protection, and the software has the function of administrator, which can limit the operation authority of general operators.
The system software has the function of post-data processing, which can support the import of multiple data files, support data filtering, and support arbitrary X-axis and Y-axis selection.
