Abstract

The invention provides a device and method for monitoring chloride ions in the atmosphere. The device comprises a shell, a chloride ion detection system and a winding mechanism, and a chloride ion collection carrier is a flexible belt wound into a cylinder; the method comprises the following steps: installing a brand-new drum-type chloride ion collection carrier; after the first-section chloride ion deposition area is exposed for preset time, pulling the first-section chloride ion deposition area to a detection position and detected; when the detection of the first section of chloride ion deposition area is finished, detecting a second section of chloride ion deposition area; and after the whole drum-type chloride ion collection carrier is used up, replacing a new drum-type chloride ion collection carrier, and continuing monitoring. The technical problem that the chlorine ion content monitoring process in the atmospheric environment is discontinuous is ingeniously solved, and the technical problems that the collection period is long, analysis data is delayed, and sampling is prone to saturation are solved.

Description

technical field [0001] The invention belongs to the technical field of chloride ion monitoring technology, and in particular relates to a device and method for monitoring chloride ions in the atmosphere. Background technique [0002] Atmospheric corrosion refers to the corrosion phenomenon of materials and their products in the atmospheric environment, and is the most common form of environmental corrosion. Materials and their products are in the atmospheric environment, due to capillary action, adsorption or chemical condensation, oxygen, water, soluble salt ions and various corrosive media in the environment condense on the surface of the material to form a thin liquid film . The existence of the liquid film changes the electrochemical state of the metal surface, causes the local area of ​​the metal surface to form a corrosion cell, generates a corrosion current, and promotes the development of corrosion. Corrosion under a thin liquid layer in the atmospheric environment...
