KR19980043080A - Counterfeit money discrimination function pen - Google Patents

Abstract

(1) the technical field to which the invention described in the claims belongs.

A method for discriminating chemical counterfeit bills by a chemical reaction test method for discriminating counterfeit bills.

(2) Technical problem to be solved

Break away from the existing large and expensive paper money discrimination means using the conventional magnetic or ultraviolet fluorescence function, and use the iodine solution for detecting chemical starch (same as starch) by the iodine-starch-reaction principle. Manufactured and distributed as a functional pen type that makes it possible to easily and easily and appropriately make proper contact.

(3) Summary of solution of invention

In case of real and fake coexistence or suspicion due to criminal process in the national financial currency banknotes, if the iodine solution of iodine-starch-reaction principle is brought into contact with the surface of the banknote in a small amount, there is no chemical change in the genuine banknote, but counterfeit money In this case, the iodine solution reacts with the starch material present in the lipid, and the chemical change principle that must be present in the violet color is a means of discriminating counterfeit money.

(4) Significant uses of the invention

It is the most economical and quick way to identify and identify the counterfeit money, which can be illegally distributed and coexist in banknotes (including Korean won, US dollar, Japanese yen, and other national currency), which is the economic means of national society. By contributing to the legal order of monetary and financial markets.

Description

Counterfeit money discrimination function pen

This invention is a counterfeit bill (including artistic manual counterfeiting, printing counterfeiting, and color copying) that may be mixed with financial currency bills (including Korean won, US dollar, and Japanese yen, etc.) which are important economic means of the national society. Gastrointestinal pulmonary reactions are quickly and easily identified by chemical drug reactions at low cost.

The present invention is a chemical counterfeit discrimination method by a chemical reaction test method in the method of discriminating counterfeit bills. In the prior art, one detection or two or more types depend on the magnetic force or fluorescent material of a specific part inherent in the printing surface during the minting process. Although it is widely used in banks and second financial sectors, it is widely used in banks and second financial sectors, but it can be used easily by general companies, households and individuals without economic burden. There is no scientific counterfeit money discriminator.

The present invention is to solve the above problems, iodine (Idostarch rection) drug used to confirm the presence of starch in the laboratory of a conventional starch (same as starch) manufacturing plant to test the presence of starch ( When the aqueous solution of iodine is brought into contact with the surface of the suspected banknote, there is no chemical change in the genuine banknote, but in the counterfeit banknote, the starch component on the lipid surface chemically reacts with iodine to produce a blue-violet color close to black. It is the invention which used the differential extraction means of a banknote.

The inventors found that iodine-starch-reactive drugs are very good for counterfeit bill discrimination, and have repeated experiments by varying the concentrations and ingredients of drugs so that they can be the best chemical composition for the authenticity of paper money. Was implemented. Iodine is a kind of halogen element, and its aqueous solution reacts with starch to produce a blue violet color. Iodine has a solubility in water of only 0.018g / 100mml (20 c. 1atm), so that it has good water solubility and dissolves an appropriate amount of potassium iodide to help dissolve iodine first. After dissolving, the solution is prepared at the proper concentration by adding water again, and the chemical solution is used instead of ink in the recording ink injection absorbing tube embedded in the structure of pen (PEN; sign pen, highlighter pen, aqueous pen, etc.) used for office or general stationery. When the process of drawing a line on the surface of the bill by injecting is performed, the iodine contact solution of the line serves as a differentiating function of counterfeit bills when the iodine solution is drawn on the surface of the bill.

Example

Dissolve 20g of potassium iodide (Potassium iodide) in 50cc of water, dissolve 13g of iodine (13g), and inject a crude solution of 950cc of water into the ink absorber tube inside the structure of the pen for general stationery. Fill it properly so that it does not overflow. The concentration of the drug composition is not limited as in the embodiment, and even if the concentration of the iodine solution is increased or decreased by 2-3 times by diluting or diluting the water, it does not impede the gastric pulmonary discrimination function. As the concentration of iodine increases, the chromaticity expressed in case of gastrointestinal discoloration becomes proportionally darker. On the contrary, as the concentration becomes thinner, the chromaticity expressed also decreases proportionally. In case of pneumonia, there is no change in chemical coloration.

This invention has no change in pneumonia due to the sample contact chemical reaction by the extremely simple act of drawing a line with the functional pen of the present invention on the surface of the banknote in which the counterfeit is suspected, but it is close to black in a short time of only 0.3-0.6 seconds in the counterfeit. The distinction of blue-purple color is manifested, so the authenticity of gastric upset is easily distinguished. The chemical discrimination of such a process is the invention of a very useful scientific counterfeit discrimination means that satisfies the convenience and speed economics to the user as much as possible.

In addition, this differential testing method does not harm any natural pollution or human health.

Claims (1)

A function pen for counterfeit waste discrimination (PEN), which is prepared by dissolving a iodine in an aqueous solution of potassium iodide and injecting a chemical discrimination solution prepared by hydrolysis into an inner absorber tube of a pen structure.
