Description

토양부식 시험기의 시편 고정장치Specimen holding device of soil corrosion tester

본 고안은 토양부식 시험기의 시편 고정장치에 관한 것으로, 더욱 구체적으로는 토양 환경에서 일어나는 지하매설물의 부식속도를 실험실적으로 측정하는 장치(이하에는 토양부식 시험기라 칭함)에 수납된 흙, 모래들에 접하는 전극시편에 대응하는 관통공을 대향하는 전지몸체에 형성하고, 전지몸체 외측에 전극시편이 착탈되는 안착홈을 형성하여 전극시편의 형성과 두께에 구애받지 않으면서 토양에 대해 전극시편의 접촉면이 항상 일정하게 되므로 다양한 전극시편을 사용할 수 있고 부식특성의 실험오차를 줄일 수 있도록 한 것이다.The present invention relates to a specimen holding device of a soil corrosion tester, and more specifically, to soil and sand contained in an apparatus for measuring the corrosion rate of underground burial occurring in the soil environment (hereinafter referred to as soil corrosion tester). Through-holes corresponding to the electrode specimens in contact with each other are formed in the battery body facing each other, and a mounting groove for detaching the electrode specimens is formed outside the battery body, so that the contact surface of the electrode specimen with respect to the soil is not affected by the formation and thickness of the electrode specimen. Since this is always constant, it is possible to use a variety of electrode specimens and to reduce the experimental error of the corrosion characteristics.

종래기술에 의한 토양부식 시험기는 제1도에 개략적으로 도시된 바와 같이, 동일한 토양조건에는 다른 두 강종의 비교실험이나 상이한 토양조건에서 동일한 강종의 비교실험이 가능하도록 복수의 전지(A, B)로 구성된 것이며, 토양환경에서의 부식속도를 측정하려는 두 강종의 X, Y라 가정하면 각각 두개의 전극을 만들어 강종 X는 전지(A)의 케이스 (1A)내측면에 장착하고 강종 Y는 전지(B)의 케이스(1B)내측벽에 장착하되, 양극전극(1)과 접하는 케이스(1A)의 절반은 흙(G)으로 채우고 음극전극(2)과 접하는 절반을 모래(S)로 채우면 흙과 모래의 통기성 차이에 의해서 양극전극(1)과 음극전극(2) 계면에서 산소포텐셜(POTENTIAL)차이가 유발되어 전지가 형성되는 것이며, 이때 흙과 접하는 양극전극(1)은 산화반응이 일어나고 모래와 접하는 음극전극(2)은 환원반응이 일어나는 것이다.As shown in FIG. 1, the soil corrosion tester according to the prior art includes a plurality of cells A and B to enable comparison experiments of two different steel species under the same soil conditions or comparison experiments of the same steel species under different soil conditions. Suppose that X and Y of two steel grades to measure corrosion rate in soil environment are made of two electrodes, and steel X is mounted on the inner side of case (1A) of battery (A) and steel Y is battery ( The case 1B of B) is mounted on the inner wall, and half of the case 1A contacting the anode electrode 1 is filled with soil G and half contacting the cathode electrode 2 with sand S is filled with soil. Due to the difference in air permeability of sand, oxygen potential (POTENTIAL) difference is caused at the interface of anode electrode (1) and cathode electrode (2), and battery is formed. At this time, anode electrode (1) in contact with soil is oxidized and sand and The cathode electrode 2 in contact has a reduction reaction. It happens.

상기에서 두 전극사이에 흐르는 전류의 크기는 강의 부식속도에 비례하게 되므로 무저항 전류계(Zero resistant ammeter)(6)를 사용하면 전지(A)와 전지(B)에 흐르는 자연부식전류(Natural Corrosion Current)의 세기는 순간순간 스위치(5)만 바꾸면 기록기(7)로 비교하여 인식할 수 있으며, 케이스(1A)(1B)에 일부 장입된 각각의 기준전극(3)은 두전지(A)(B)의 환원포텐셜을 비교하기 위한 것이다.Since the magnitude of the current flowing between the two electrodes is proportional to the corrosion rate of the steel, when using a zero resistant ammeter (6), the natural corrosion current flowing through the battery (A) and the battery (B). The intensity of can be compared and recognized by the recorder 7 by changing only the instantaneous switch 5, and each reference electrode 3 partially inserted into the cases 1A and 1B has two batteries A and B. It is for comparing the reduction potential of.

상기와 같은 종래기술의 토양부식 시험기에서 전극(1)(2)을 원형으로 가공하여 흙이나 모래와 접하는 전면(前面)을 제외한 나머지 면은 토양과 접하는 것을 방지하기 위해 아스팔트로 도포하여 절연시키고, 전극(1)(2)의 배면에 나사공(1C)을 형성하여 케이스(1A)외부에서 체결부재(8)로 결합하게 되므로 전극(1)(2)의 두께에 제한을 받게 되는 것이다.In the soil corrosion tester of the prior art as described above by processing the electrode (1) (2) in a circular shape except the front (front) contact with the soil or sand is coated with asphalt to prevent contact with the soil and insulated, Since the screw holes 1C are formed on the back of the electrodes 1 and 2 to be coupled to the fastening member 8 from the outside of the case 1A, the thickness of the electrodes 1 and 2 is limited.

또한 전극(1)(2) 가공시에 받은 내부 응력(stress)을 제거하기 위해서는 시편전극(1)(2)을 조금 크게 절단하여 테두리를 재연마하는 이중작업을 감수해야만 되는 것이었다.In addition, in order to remove the internal stress received during the processing of the electrodes 1 and 2, the specimen electrodes 1 and 2 had to be cut a little larger to undergo a double operation of regrinding the edges.
