Brief introduction: Cycle corrosion test is a kind of exposed more real than traditional constant state of salt spray test. Usually contains both wet and dry seasons because the actual outdoor exposure environment, simulate the natural, periodic conditions, the laboratory accelerated tests to be meaningful. Research shows that after cycle corrosion test, the sample relative corrosion rate, the structure, morphology and outdoor corrosion results are very similar. Therefore, cycle corrosion test than traditional salt fog spray method, closer to the real outdoor exposure. They can effectively evaluate a lot of corrosion mechanisms, such as general corrosion, galvanic corrosion, crevice corrosion and so on. Cycle corrosion test aims to reproduce the corrosion types of outdoor corrosion environment. Test the samples exposed to a range of different conditions of circulation environment. Simple exposure cycle, such as Prohesion test, it is the samples exposed to loop composed of salt spray and dry conditions. More complex automotive testing method in addition to salt fog and drying cycle, also calls upon damp and static cycle, etc. Initially these test cycle is done by manual operation, laboratory operators move the sample from the salt fog spray tank to the humidity chamber, then moved to dry or static device, etc. We adopt the microprocessor control test box can be automatically finish the test steps, reduce the uncertainty of the test. Technical parameters: 1. The laboratory temperature range: 20 ℃ ~ 60 ℃ 2. The relative humidity: 35% 98% RH (+ / - 3%) 3. The saturated barrel temperature: 47 ℃ to 70 ℃ 4. The temperature uniformity: plus or minus 2 ℃ or less 5. The temperature volatility: + / - 1 ℃ or less 6. The test of time: 0-999 - H, M is adjustable 7. The settlement: 1-2 ml / 2000 px2 / h 8. Spray method: programmable spray, damp and hot, quiet place 9. Mist way: by air extrusion line of fog 10. Rack: according to the requirements
