Problems solved by technology
The traditional laboratory method needs to take a sample of the painting and bring it back to the laboratory for testing. It is a destructive or minimally destructive method, and it is expensive and complicated
For the detection of existing ancient architectural color painting pigments, the laboratory detection method is too cumbersome and cannot be used for in-situ detection, which is not applicable to the detection of a large number of color painting samples
Especially for the precious color paintings with a long history, the detection method of loss or slight loss is not applicable

Embodiment Construction
[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] The technical problem to be solved by the present invention is to provide an in-situ non-destructive and portable detection method, which can simply, quickly and accurately measure elemental information, and accurately detect the color of pigments in various colors through a handheld fluorescence spectrum analyzer (HH-XRF). Element composition, and judge the type of pigment according to the information of color elements.
[0041] Such as figure 1 As shown, a kind of in-situ non-destructive, portable ancient architectural color painting inorganic pigment detection method of the present invention mainly comprises the following steps:
[0042] (1) Select the detection points acc...

The invention discloses an in-situ lossless and portable detection method for detecting inorganic pigments of color paintings of ancient buildings. The method comprises the following steps: (1) selecting detection points according to the type of a to-be-detected color painting, before the detection point is determined, firstly investigating the type, color composition and color superposition relation of the to-be-detected color painting sample on site, and then selecting the detection point; (2) preprocessing different diseases of detection points in the to-be-detected color painting; (3) judging color developing elements of the detection points according to the age information and colors of the detection points, processing data corresponding to the detection points, when the element concentration value is smaller than or equal to 0.1%, ignoring the corresponding element concentration, and for the data of the three detection points at different positions of the same color, selecting the group of data with the maximum color developing element concentration value as the final data of the detection point corresponding to the color; and (4) explaining the source of the color developing element according to two conditions of completeness and incompleteness of the detection point, and deducing the type of the pigment.
Description
technical field [0001] The invention relates to the technical field of cultural relics and archaeology, in particular to an in-situ non-destructive and portable method for detecting inorganic pigments in color paintings of ancient buildings. Background technique [0002] The current protection of cultural relics should follow the principle of "not changing the original state of the object". Therefore, it is necessary to investigate the shape, color and pigment type of the original color painting before restoring the ancient architectural color painting. In addition, the types of colored paints are an important basis for dating colored paintings, and ultimately serve the research on the history of ancient building repairs and architectural historiography. The detection of pigment species has become an important research topic. At present, the methods for detecting pigment types are mainly laboratory methods, such as: scanning electron microscopy energy spectroscopy (SEM-EDX)...
