Problems solved by technology

[0003] This identification and evaluation technology cannot directly display the anti-corrosion performance of the coating, but can only display the service life of the coating, and cannot display important indicators related to the degree of corrosion in the coating, nor can it quickly evaluate the performance level
At the same time, experiments in the laboratory for coating performance testing are inefficient, and evaluation results cannot be obtained in real time

Abstract

The invention provides a method for evaluating the corrosion resistance of a steel structure coating. The method comprises the following steps: acquiring a to-be-detected infrared spectrum of the to-be-detected steel structure coating; substituting the infrared spectrum to be detected into a preset intelligent identification model for calculation to generate coating performance data; and evaluating the coating performance data based on a preset grade evaluation standard to obtain an anti-corrosion performance evaluation result of the to-be-tested steel structure coating. According to the method, the coating performance data is calculated by using the intelligent identification model, so that the rapid grade evaluation of the steel structure anticorrosive coating is realized, and the efficiency of steel structure performance detection is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of construction engineering performance detection and appraisal, and in particular to a method, system, server and storage medium for evaluating the anticorrosion performance of steel structure coatings. Background technique [0002] At present, the performance identification and evaluation technology of anti-corrosion coatings for steel structure engineering mainly adopts electrochemical methods. By testing the electrical impedance of the coating and comparing the service life-electrical impedance standard curve of the material, the remaining service life of the engineering coating is predicted. The standard curve corresponding to the obtained coating service time and material electrical impedance parameters is compared with the coating electrical impedance data collected on site to calculate the remaining service life of the anti-corrosion performance of the solid engineering coating.
