1、 Equipment Introduction:

1. This product uses a fluorescent ultraviolet lamp that can simulate the UV spectrum in sunlight well, and combines temperature control and other devices to simulate the discoloration, brightness, and intensity reduction of the material; Factors such as cracking, peeling, powdering, oxidation, and damage caused by sunlight (UV band), high temperature, and dark cycles, as well as the synergistic effect between ultraviolet light and temperature, weaken or fail the single light resistance or temperature resistance of materials. Therefore, it is widely used for evaluating the weather resistance of materials, and the corrosion of metal materials without protection is influenced by many environmental factors, mainly depending on the type of metal material and the type of environment.

It is impossible to design a laboratory accelerated corrosion test room that includes all environmental factors that affect corrosion resistance. Therefore, it is necessary to simulate the factors that play a major role in the corrosion of metal materials to design laboratory tests. This device is designed to simulate and increase the impact of the environment on metal materials exposed to salt contaminated outdoor atmospheres that can accelerate corrosion. The equipment includes a test method for cyclically exposing the sample to salt spray, dry, and humid environments. This equipment test is a comparative test, and the test results cannot predict the long-term corrosion resistance of the same metal material used under these environmental conditions. However, this method can still provide valuable information on the relevant properties of materials exposed to salt contaminated environments similar to the experimental 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 advantage of this equipment test is that it can better reproduce corrosion that occurs in outdoor salt polluted environments.

2. This equipment is suitable for accelerated corrosion testing of metals and their alloys, metal coatings (anodic and cathodic), conversion coatings, anodic oxidation coatings, organic coatings on metal materials, etc

3. Using fluorescent ultraviolet lamps that can simulate the UV spectrum in sunlight well, combined with temperature control devices to simulate the discoloration, brightness, and intensity reduction of materials; Factors such as cracking, peeling, powdering, oxidation, and damage caused by sunlight (UV band), high temperature, and dark cycles, as well as the synergistic effect between ultraviolet light and temperature, weaken or fail the material's single light resistance or single temperature resistance, making it widely used for evaluating the material's weather resistance.
