[0071]

[0072] 1. Elements labeled with chemical elements (S-DNA): In order to create elements that can be attached to the surface of the object and penetrate into the interior of the object, it can be combined with the object in molecular form to form an integral body, which will not damage the surface and internal structure of the object, and is not easy to be separated or destroyed. , high temperature resistance (1650°C), wear resistance (chemical elements will automatically transfer to other parts of the item when rubbed), acid and alkali resistance, insoluble in general organic and inorganic solvents, does not disappear with changes in the state of the item, and can be used on the spot in real time Rapid detection, identification and information feedback. According to the different properties of the items, the formula and ratio of chemical elements can be adjusted to ensure personal safety and health, and it will not damage or pollute the environment. It is suitable for ...

Abstract

The disclosed chemical element labeling method comprises: setting chemical element label included one or more elements with atomic number more than 22 on target, detecting the nominal spectrum data of label by X fluorescence detector to compare with detected data in security database. This invention does not dissolve general organic or inorganic solvent, has well stability, and introduces well detection accuracy without damage to target surface.

Description

technical field [0001] The present invention relates to a method for marking by using chemical elements, also relates to equipment for realizing the method, and further relates to the chemical element marking (namely: synthetic-DNA, S-DNA for short) used in the marking method. Background technique [0002] A successful item marking scheme should provide a means of marking items in a secure manner and identifying items within the scope of the law for the legal holder's trade name, trademark, reproduction title and certificate, etc. [0003] The marking methods currently in use mainly include the following categories: [0004] 1. Liquid coding [0005] Liquids are like paints that are applied to a surface and are usually supplied in small bottles along with spray brushes. A secure database establishes a unique fluid code for each customer. It is suitable for a wide range of commercial or family property protection fields. A small sample is taken from the marked object and ...
