Working Principle of Salt Spray Test Chamber:
- Salt spray generation: A salt spray test chamber is usually equipped with a salt solution supply system. The commonly used salt solution is sodium chloride solution, which forms chlorine and hydrogen by electrolytic decomposition. Chlorine and hydrogen further react to produce salt spray, which is blown onto the specimen by a fan.
- Salt spray uniformity: A fan is installed inside the salt spray test chamber, which blows the generated salt spray onto the specimen evenly through a circulating fan to ensure that the surface of the specimen is evenly corroded by salt spray.
- Temperature control: The salt spray test chamber can usually control the temperature of the specimen. Temperature control can be achieved through a heater and a cooling device, so that the specimen can be subjected to salt spray corrosion tests under different temperature conditions.
- Salt spray removal: An exhaust device is installed in the salt spray test chamber to remove the gas and steam generated on the specimen. This can maintain the stability of the internal environment of the salt spray test chamber and avoid interference with the specimen.
Features:
| 1. | Import grey-white P.V.C plate,special treatment on corrosion resistance.V shape steel shelf and stainless steel to hold the item, make sure the tested in 30 degrees. The machine can slide with wheels. |
| 2. | Exquisite workmanship,good-looking appearance,clear transparency,pneumatic open. |
| 3. | Automatic and manual water supply system,can automatic and manual water supply when it lower than the water level, which will not stop the test and meet different environment requirement. (automatic water supply just need to insert the pipe) |
| 4. | Nozzle:salt power with conical disperser,functions like: guide the salt spray,adjust the salt spray volume and average salt spray. |
| 5. | High precision multi-functional timer, memory when power failure, can continue working when power on, can avoid to do the test again. |
| 6. | Steam heating in the test,quick and average, shorten the standby time. |
| 7. | Automatic control, with detect fault early warning system.Light on and buzzer warning when fault happen. |
| 8. | 2 internal salt collecting cylinders, better protection than the usual external type. |
| 9. | Overload short circuit protection, prevent to damage the electronic accessories inside the meters and instruments. |
| 10. | Enclosure waterproof-seal, prevent the salt escape. |
| 11. | Import digital display temperature controller,controlled by PID,error is ±0.1℃. |
| 12. | Temperature Range:1:Chamber:35℃–Barrel:50℃(Can set random)
2:Chamber:47℃–Barrel:63℃(Can set random) |
| 13. | Reagent bottle : Easy to wash and hard to break. |
| 14. | Heating Rate:1:Chamber,normal temperature—→35℃ about 35min
2:Pressure Barrel,normal temperature—→47℃ about 15min |
| 15. | Temperature Accuracy:±1℃ |
