Atmospheric corrosion behavior simulation monitoring device and method for galvanized steel

Abstract

The invention discloses a galvanized steel atmosphere corrosion behavior simulation monitoring device. The galvanized steel atmosphere corrosion behavior simulation monitoring device comprises a cabin, a weighing part, a temperature control part, a humidity control part, a galvanometer, an insulating part and a processor; the cabin is provided with a monitoring chamber and a coating window. The weighing part is connected with the processor; the temperature control part is used for adjusting the temperature in the monitoring chamber; the humidity control part is used for adjusting the humidity in the monitoring chamber. The insulating part is used for fixing a first electrode made of galvanized steel of a measuring probe and a second electrode made of galvanized matrix steel, both one end of the first electrode and one end of the second electrode are flush with one end surface of the insulating part, and the end surface of the insulating part forms a coating surface; the other end of the first electrode and the other end of the second electrode are respectively connected with the galvanometer, and the galvanometer is connected with the processor. The galvanized steel atmosphere corrosion behavior simulation monitoring device is applicable to galvanized steel atmosphere corrosion monitoring in different atmospheric environments, and the experimental period is short.

Description

technical field

[0001] The invention relates to the field of corrosion behavior simulation monitoring, in particular to a galvanized steel atmospheric corrosion behavior simulation monitoring device and method thereof. Background technique

[0002] During the use of galvanized steel, it is often corroded by the atmosphere, and the current method of monitoring the corrosion of galvanized steel is generally to use the field exposure test; the field exposure test can accurately obtain the corrosion data and characteristics of galvanized steel materials in the natural environment , can provide reliable parameters for production and design, but the experiment period is long, the sampling interval is long, and it is difficult to evaluate the corrosion behavior of materials in real time. Contents of the invention

[0003] Based on this, it is necessary to provide a galvanized steel atmospheric corrosion behavior simulation monitoring device and method suitable for galvanized stee...
