Evaluation method and evaluation system for protective coating

Abstract

The invention relates to a protective coating evaluation method and system, and the method comprises the steps: obtaining the performance index data of a plurality of protective coatings under different environment test conditions, and each protective coating comprises a plurality of pieces of performance index data under different environment test conditions; evaluating each performance index data by adopting a principal component analysis method; and carrying out environmental adaptability grading on the plurality of protective coatings according to the evaluation result. Through the protective coating evaluation method, evaluation results of a plurality of protective coatings can be intuitively obtained, and comprehensive evaluation results can be accurately performed on the plurality of protective coatings in different environments; compared with a traditional method, the method has the advantages that multiple protective coatings can be comprehensively evaluated at the same time, a unified optimization suggestion is given, and the efficiency of the evaluation process and the availability of the evaluation conclusion are improved; the protective coating with good environmental adaptability can be preferably selected according to the evaluation result, and a reliable reference is provided for selecting the protective coating for equipment in all industries.

Description

technical field [0001] The invention relates to the technical field of corrosion and protection, in particular to an evaluation method and evaluation system for a protective coating. Background technique [0002] Due to the vast territory of our country and the wide range of equipment service, when the equipment is used in various typical environments, especially in harsh environments, it will be affected by various environmental factors, resulting in a decline in environmental adaptability and corrosion protection. Almost all materials will produce different degrees of corrosion damage during use or storage, resulting in damage to the structure of the equipment composed of it, performance degradation or functional failure. Coating protective coatings on the surface is the main means to ensure and improve the corrosion protection ability of equipment. At the beginning of product design, reasonable selection of materials and appropriate surface protection measures are the mos...

AI Technical Summary

Problems solved by technology

Equipment may be placed under various natural environmental conditions, involving a variety of climatic regions, and various climatic conditions have different effects on the protective coating of equipment, which makes it difficult to pass a single performance test (such as appearance, mechanical properties, etc.) of protective coatings. , electrical properties, electrochemical properties, etc.) to assess its pros and cons of the traditional optimization method is no longer applicable

In addition, when evaluating multiple coatings, the traditional method will face the difficulties of a large number of samples, a large amount of repetitive work, and difficulty in convenient and simple optimization; and when multiple failure characteristics exist at the same time, the evaluation of multiple protective coatings Optimization relies heavily on the subjective experience of experts, which is not objective enough; at the same time, there are various types of materials with different performances, and the corrosion of materials is complicated, which often brings great difficulties to the material selection work in the design stage.
