preparation example Construction

[0033] The invention discloses a method for preparing a protective layer of archaeological cultural relics, the steps of which are as follows:

[0034] 1. Archaeological excavators clean up artifacts or relics, so that the exposed volume of the artifacts or relics to be extracted exceeds half of the body, and the bottom of the artifacts or relics is as empty as possible;

[0035] 2. Use a hand-held 3D scanner to perform 3D scanning on the exposed part of the object to be extracted or the remains to obtain its 3D point cloud data;

[0036] 3. Use the 3D point cloud data obtained from 3D scanning to establish a 3D model of the exposed part of the artifact or remains to be extracted;

[0037] 4. Using rigid thermoplastic material as the base material, use the fusion deposition molding method to use the 3D printer to print the physical model of the object to be extracted according to the 1:1 three-dimensional model;

[0038] 4. Use silicone rubber to paint on the surface of the p...

Embodiment approach

[0045] According to the content and implementation steps of the present invention, taking a damaged and seriously deformed Dakouzun unearthed from a site in the late Shang Dynasty as an example, it was fixed in situ and then completely extracted. The implementation method is as follows:

[0046] 1. The archaeological excavators cleaned up the surroundings of the cultural relics as much as possible. The Dakouzun exposed three-fifths of its body, and the bottom of the utensils was also emptied as much as possible. They were cleaned and supported, and exposed as much as possible without affecting the support and weighing of the utensils. More parts for 3D scanning and subsequent package protection;

[0047] 2. Use a hand-held 3D scanner to perform 3D scanning on the exposed parts of Dakouzun to obtain 3D point cloud data, and then transmit the collected data to the data processing server;

[0048] 3. Through the data processing server, use the 3D point cloud data to establish a ...

Embodiment 2

[0055] According to the content and implementation method of the present invention, take a section of muddy, multi-cracked, and high-water content ivory unearthed from a site in the late Shang Dynasty as an example, and effectively and completely protect and extract it. The implementation method is as follows:

[0056] 1. Archaeological excavators clean up the ivory so that more than three-quarters of the ivory's volume is exposed;

[0057] 2. Use a hand-held 3D scanner to perform 3D scanning on the exposed ivory, obtain 3D point cloud data of ivory, and transmit it to the data processing server;

[0058] 3. Through the data processing server, use the 3D point cloud data to establish a 3D model of the exposed part of the ivory;

[0059] 4. Using acrylonitrile-butadiene-styrene copolymer as the material, use the fusion deposition molding method 3D printing technology to print the physical model of the exposed part of the impression according to the three-dimensional model at a...

Abstract

The invention provides an archaeological cultural relic protection layer. The archaeological cultural relic protection layer comprises an inner protection layer and an outer protection layer which are tightly attached to each other, the inner protection layer is made of a flexible material, and the outer protection layer is made of a rigid thermoplastic material. The invention further provides a preparation method of the archaeological cultural relic protection layer. The preparation method comprises the steps of three-dimensional scanning, model building, 3D printing, inner protection layer manufacturing, outer protection layer manufacturing and the like. The invention further provides a using method of the archaeological cultural relic protection layer. The inner protection layer is slowly attached to the surface of a to-be-extracted object, no gap is reserved between the inner protection layer and the to-be-extracted object, the inner protection layer and the to-be-extracted object are tightly attached, then the outer protection layer is arranged on the surface of the inner protection layer in a sleeving mode, extraction can be carried out after overall fixation, the inner protection layer is tightly attached to the to-be-extracted object, in-situ reinforcement and shape fixing can be carried out on the to-be-extracted object, and damage to cultural relic surface ornaments and decorations caused by creeping of the protection layer in the extracting and transferring process is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of protection of archaeological cultural relics, in particular to a protective layer of archaeological cultural relics, a preparation method and a use method. Background technique [0002] The cultural heritage buried underground is an important witness to the development of civilization in human society, and it is also a precious and non-renewable cultural resource. Some cultural relics have been subjected to various media and extrusion forces for a long time in the buried environment, and their texture and structure have become particularly fragile, or the information contained in the cultural relics has only traces of information left, which is extremely vulnerable to damage. For example, the ivory unearthed from the Sanxingdui ruins has almost completely decomposed its organic matter, developed micropores and cracks, and has almost no mechanical strength. It only relies on the surface tension of water an...
