Problems solved by technology

However, due to the high price and difficulty of purchasing externally, self-made laminating is usually used.
[0006] Self-made lamination is to use the formula recommended by the standard "DL / T 884-2019 Technical Guidelines for Metallographic Inspection and Evaluation of Thermal Power Plants" for laboratory self-made, but this method has strict requirements on personnel levels and is greatly affected by the environment

Abstract

The invention discloses a metallographic coated AC test paper toughness enhancing method, and particularly relates to the technical field of mortar coating machines. The strengthening method comprises the following steps: determining raw materials, preparing a preparation solution of AC test paper in a first scheme, preparing a preparation solution of AC test paper in a second scheme, shaking a solution bottle, and forming a metallographic film after one day. The method is mainly used for enhancing the toughness of the metallographic coated AC test paper, the problem of film stripping difficulty in the preparation process can be improved to a certain extent to obtain the AC test paper with high success rate, the proportioning components of the conventional test paper are improved, the agar is added, the content of other components is changed, the toughness of the AC test paper is improved, and the film forming rate is greatly improved.

Description

technical field [0001] The invention relates to the technical field of metallographic coating, more specifically, the invention relates to a method for strengthening the toughness of AC test paper with metallographic coating. Background technique [0002] In the on-site inspection, metallographic analysis is the most effective and effective way to evaluate the aging degree of various pipelines. It can visually detect the aging degree of the tissue and avoid the risk of accidents due to aging. [0003] Conventional metal structure analysis will conduct metallographic analysis by cutting, inlaying, and grinding the inspected workpiece. However, during on-site inspection, due to labor hours and cost issues, it is not allowed to destroy large components. Therefore, when detecting the structure of large components, metallographic complex technology is particularly important. [0004] The metallographic replica technology is to attach the prefabricated replica material to the tes...
