Description

[Detailed explanation of the idea]

The present invention relates to a metal material discriminator, and more specifically, it is capable of semi-quantitatively detecting multiple alloy elements in a metal material simultaneously and non-destructively. The object of the present invention is to provide a metal material discriminator capable of simple analysis with high reliability and suitable for on-site work used for rapid sorting. In the conventional metal material discriminator, as shown in Fig. 1, the anode end 3 is brought into contact with the metal object 1, and the cathode end 4 is a strip of absorbent cotton or the like impregnated with an electrolytic solution using conductive material tweezers or the like. The metal specimen 1 is brought into contact with the aqueous substance 5 sandwiched therebetween, and an electric circuit is formed between them via the power source 2. Next, a predetermined current is passed through the electric circuit to identify the metal material based on the color reaction between the electrolytic solution impregnated into the aqueous substance 5 and the metal ions eluted from the metal specimen 1. In such a metal material discriminator, the cathode end 4 is
(1) Only one alloy component in a metal material can be detected at a time. (2) Qualitative or semi-quantitative detection of multiple alloy components in one metal specimen cannot be detected simultaneously. (3) Qualitative or semi-quantitative detection of specific components of multiple metal samples cannot be detected simultaneously. There are other problems. The present invention is a metal material discriminator that solves the above problems. Hereinafter, the metal material discriminator of the present invention will be described in detail with reference to FIGS. 2 to 4. That is, as shown in FIG.
An insulating partition plate 7 having at least two spaces 8 is placed on the upper surface of the cell in order to insert the aqueous substance 5 impregnated with an electrolytic solution. As a result, one opening of the space 8 of the insulating partition plate 7 is closed by the cathode plate 6. The material of this insulating partition plate 7 is plastic, glass,
Wood, rubber, etc. are preferred. Next, as shown in FIG. 3, a water-absorbing substance 5 such as absorbent cotton impregnated with an electrolytic solution is inserted into each of the plurality of spaces 8 defined in the insulating partition plate 7. This electrolytic solution contains a reagent that undergoes a color reaction with the metal ions eluted into the detection portion of the metal specimen 1, and the contents of the reagent suitably used therein will be described later. After inserting the aqueous substance 5 into the space 8 of the insulating partition plate 7, the metal object 1 is placed on the surface of the insulating partition plate 7 opposite to the side where the cathode plate 6 is located. Place in contact. That is, one opening of each space 8 of the insulating partition plate 7 is closed by the cathode plate 6, and the other opening is closed by the metal object 1. However, it is not a requirement that the opening be completely blocked, but may be only partially blocked. After that, by connecting the cathode side of the DC power supply 2 to the cathode plate 6 and the anode side to the metal object 1, an electric circuit from the cathode plate 6 to the metal object 1 via the aqueous substance 5 is established. Form. A water-absorbing substance 5 such as absorbent cotton impregnated with an electrolytic solution containing a reagent that causes a color reaction with each metal ion such as Ni, Cr, Mo, and Cu reacts with each metal ion eluted from the metal specimen 1. The metal specimen 1 is determined by the presence or absence of coloration and its strength
Qualitative or semi-quantitative detection of alloy components can be detected at the same time. Examples of suitable reagents in the electrolyte used for qualitative or semi-quantitative determination of Ni, Cr, Mo, Cu, etc. among the alloying elements of the metal specimen 1 described in the above example are shown in the following table. It is.

[Table] Next, as shown in FIG.
When using a conductive wire 1 inside the cathode plate 9
By disposing 0, current can be applied between the anode end 3 and the cathode end 4. The non-conductive cathode plate 9 may be made of plastic glass, wood, rubber, or the like. The conductive wire 10 may be made of platinum wire, but it is expensive, so only the cathode end 4 is made of platinum, and the other conductive wires are made of platinum.
It is preferable to join using copper wire or aluminum wire. As described above, the metal material discriminator of the present invention can quickly sort out a specific metal material from a large amount of dissimilar metal materials, and simultaneously perform qualitative or semi-quantitative analysis of multiple alloy components in a single metal specimen to be identified. It has a detectable effect. Furthermore, there is an effect that qualitative or semi-quantitative detection of specific components of a plurality of metal objects can be detected simultaneously.
