Jade nondestructive detection sample model and manufacturing method thereof

Abstract

The invention discloses a jade nondestructive detection sample model and a manufacturing method thereof. The sample model comprises a jade model plate, wherein a smooth planar area, a bucket-shaped thinned area, a concave thinned area, a concave gold film area, a concave carbon film area, a cylindrical thinned area, a penetrability varying area, a light dispersion prism area, a raw material remain area, a cutting remain area, a color vector area, a special lighting area and a marking area are arranged on the jade model plate. The manufacturing method of the sample model comprises the following steps: A. selecting materials; B. cutting; C. polishing; D. carving; E. polishing; F. labeling an ingredient labeling area, a name labeling area, a lattice labeling area and a color vector area depending on a detection result; G. finishing manufacturing of the sample model, and packaging. The sample model disclosed by the invention fills the blank that the fields of domestic and international jade detection and identification teaching and research fail to acquire 15 specified national standard data and conclusions rapidly on the premises of not dividing a sample and not changing state of the sample detected.

Description

Technical field [0001] The invention belongs to the technical field of jade detection, and specifically relates to a jade nondestructive testing sample model and a manufacturing method thereof. Background technique [0002] (1) There are currently no jade samples specially used for non-destructive testing in China. [0003] my country is one of the few countries in the world with a unique jade culture. There are many types of natural jade listed in my country’s national standards. Due to the high value of jade, in the process of meeting social needs, non-destructive scientific and technological identification and testing techniques are in practice. Increasingly important significance, but as of now, my country has no jade non-destructive testing technology system that can meet the current stage of scientific and technological development testing and application, and there is no jade sample that can support this technology system. [0004] (2) The development of international and dome...

AI Technical Summary

Problems solved by technology

[0008] 4. At present, the concept and classification of jade are not intuitive and clear, and it is difficult to unify the classification and identification. The understanding and grasp of the classification standards of Hetian jade by inspection agencies, dealers and consumers are very different, resulting in fakes and fakes. Good phenomena are common, and jade identification often causes quality disputes, which also restricts the development of the jade industry

[0012] 3. At present, although most of the above-mentioned advanced instruments used in our country are imported, some core technologies form barriers, so the price is high, and many domestic laboratories are difficult to equip. Declining, Non-destructive Jade Jewelry Testing Has Been Popularized

[0014] 1. Irregular samples with various properties: Since there are no national-level Hetian jade or other jade standard material test samples in China, the existing identification and testing text standards cannot correspond to physical standards, and can only be based on raw materials, jade products and jade characteristics Test and test sample comparative analysis

[0015] (1) Rough stone: Irregular in shape, unable to be observed and studied in detail

[0016] (2) Jade: It cannot meet the measurement of hardness and special light effects, and some inlaid and hollow jades cannot measure density and other indicators

[0019] (5) Solution: only for component research

[0021] On June 1, 2010, the Quality and Technical Supervision Bureau of the Xinjiang Autonomous Region issued a recommended rather than non-mandatory Hetian jade local standard, including the "Hetian Jade Physical Standard Sample", ending the Hetian jade standard with only text descriptions and no physical samples The history of reference has made domestic Hetian jade identification a big step forward, but the preparation method of this kind of physical sample is simple, it is just a wedge-shaped cube with a slope, and it must be tested again on the test sample block with this local standard sample. Sampling or reprocessing

The industry believes that this will play an important role in regulating and guiding my country's jade industry. However, this specification is a combination of cuboid jade samples with a length of 3 cm, a width of 2 cm, and a thickness of 1 cm. The national standard for each type of Hetian jade only represents The lowest limit of the color of the jade type, without other special modeling meaning and function

It is only a standard substance that is "a part of the national standard" in the general sense. According to the requirements of the national standard substance, the national standard of Hetian jade should correspond to the existing written national standard. Using this jade standard sample can holographically collect the national standard Everything listed, but must also be re-sampled on the test block or re-processed destructively

[0023] (7) Thin slices: At present, there are no jade thin slices specially used for optical detection purposes in my country. For a long time, only rock thin slices can be used for optical detection purposes in mineral and rock identification based on geology and petrology.

The flakes are too thin, which has limitations in application, such as hardness, refractive index, density, etc. cannot be measured. In addition to relying on sophisticated instruments, the production also requires dexterous hands. The production is difficult, costly, and lossy

The domestic quantity is very small, scattered in professional laboratories, and can only be used in the laboratory, it is difficult to promote in the society

[0032] 3. The identification process is complicated:

Since there is no physical standard corresponding to the national standard, the implementation of the jade standard is superficial, and the testing agencies in various places cannot really implement the jade testing one by one according to the national standard. The test certificate only indicates the hardness, density, refractive index, etc. Using simple instruments to observe with the naked eye has weakened the authority of testing institutions and testing conclusions, making the development of modern testing technology in jade identification seriously lagging behind
