2. The salt solution after spraying shall not be reused except for the baffle block.
3. If the salt spray box uses compressed air, it requires:
1. The compressed air entering the sprayer must first remove impurities such as oil and sand.
2. Make adjustments to the spray pressure so that the salt spray settlement meets the requirements of 5.3.2 of the TB/T 5170.8-2008 standard.
3. In order to prevent the crystal salt from clogging the spray port, the relative humidity of the spray port should be no less than 85%.
