Salt water lees: In order to ensure uniform spraying, there should be a device to maintain a certain liquid level. Adjust the spray pressure, the temperature of the saturated tower water and the position of the baffle to make the salt spray settling amount and collection speed in the salt spray test box conform to the salt spray settling speed. After 24 hours of spraying, it is 1 ~ 2ml / h per 80cm2 area; The sodium concentration is 50g / L ± 5g / L; the pH range is: neutral salt spray test is 6.5 ~ 7.2, acetate salt spray test is 3.1 ~ 3.3, copper accelerated acetate salt spray test is 3.1 ~ 3.3 Regulations.
