Embodiment 1

[0040] In this example, taking the coating system of sulfuric acid anodization + TB06-9 + TS70-60 as an example, the evaluation method of coating protection performance is described in detail.

[0041] Coating test information: The outdoor air exposure test of the offshore platform was continuously carried out for 4 years by using a rectangular flat sample coated with sulfuric acid anodization + TB06-9 + TS70-60 multi-layer coating system.

[0042] The specific steps for the evaluation of the protective performance of the coating:

[0043] Step 1: According to the coating application occasion (marine atmospheric environment), select the seven items of powdering, cracking, blistering, rusting, peeling, thickness loss and adhesion as the evaluation index of coating protection performance, and obtain the selected The measured value of the evaluation index;

[0044] Step 2: Carry out dimensionless processing on the evaluation indicators in step 1. Specifically, use the 0-5 level ...

Embodiment 2

[0061] A coating protection performance evaluation equipment, including a computer, the computer includes a memory, a processor, and a computer program stored on the memory and operable on the processor, wherein the processor implements the following steps when executing the program :

[0062] Step A: Select the evaluation index, input the measured value of the evaluation index, the computer processor receives the input measured value of the evaluation index and compares it with the stored data in the database, and outputs the index evaluation value X j ; The evaluation index includes gloss, color difference, chalking, cracking, blistering, rusting, peeling, thickness loss and / or adhesion drop rate;

[0063] The stored data in the database includes Table 1, Table 2, the grade classification standards for gloss, color difference, chalking, cracking, blistering, rust, and peeling in GB / T 1766-2008, and the coating in Table 3 Comprehensive grade evaluation standard of protective...

Abstract

The invention provides a method for comprehensively evaluating coating protection performance. The method comprises steps of selecting evaluation indexes according to the application occasion of the coating, converting the actually measured values of the selected evaluation indexes into index evaluation values; calculating the comprehensive weight value of each evaluation index by integrating a subjective weighting method and an objective weighting method; and giving an evaluation conclusion of the coating protection performance based on the comprehensive weight values and a comprehensive evaluation standard of the coating protection performance. The invention provides a new evaluation method for the evaluation field of coating protection performance, and the method provides an accurate and reliable basis for the optimal and reasonable use and maintenance of a coating material. The invention also provides a device for evaluating coating protection performance. The device for evaluatingthe coating protection performance greatly simplifies evaluation processes, improves work efficiency, and achieves accurate and reliable evaluation results.

Description

technical field [0001] The invention relates to a method and equipment for comprehensive evaluation of coating protection performance based on indicators such as aging, thickness loss, and adhesion drop rate. Background technique [0002] Coating materials are a class of chemical materials that can be coated on the surface of the substrate and form a continuous film that adheres firmly, and have anti-corrosion, decoration or other special functions. Applying a coating on the surface of the substrate can effectively isolate the influence of the external corrosive environment or corrosive medium, greatly reduce the corrosion of the substrate material, and prolong the service life of the structure or parts. It is the most important means in the anti-corrosion technology of equipment products. Since the main function of the coating is to protect the materials used in equipment products (such as steel, aluminum alloy, titanium alloy, magnesium alloy and other metal materials, com...
