Describe the formation process of salt spray in salt spray test machine
The cause of salt spray is mainly due to the intense disturbance of seawater in the ocean, the breaking of wind and waves, the formation of a lot of foams and bubbles in the waves, and the formation of tiny water droplets when the bubbles burst. Most of the water droplets fall due to gravity, and some are in the same vortex diffusion. It is distributed in the sea while maintaining a balanced state. They rise into the air with the airflow, and evolve into a dispersing system through the processes of cracking, evaporation, and mixing to form an atmospheric salt core. These salt cores can reach an altitude of more than 2,000 meters with the updraft. These sea salt particles or salt spray distributed on the sea surface are transported to the land along with the wind and the flow of the river, and can drift to the inland many kilometers away from the ocean with the wind. In the typhoon, it can penetrate hundreds of kilometers inland. Don't underestimate these small salt sprays, they can cause extremely serious damage to some metal objects, auto parts, etc. Therefore, the salt spray test machine came into being. The salt spray tester can accelerate the corrosion of materials or products under certain temperature and relative humidity conditions, and reproduce the extent of damage to materials or products in a certain period of time. It can be used to assess the resistance of materials and their protective layers to salt spray corrosion, as well as the comparison of process quality of similar protective layers. It can also be used to assess the resistance of certain products to salt spray corrosion. This is what the salt spray test machine can play. The role.
