본 발명은 금속물질의 표면에 생성되는 부식생성물을 제거하기 위한 방법에 관한 것으로, 제청제의 건조와 유효수소의 이탈을 방지하기 위해 직물부재를 이용하여 제청효과를 높이는 방법이 사용된다.The present invention relates to a method for removing the corrosion products generated on the surface of the metal material, a method of increasing the decontamination effect by using the fabric member to prevent the drying of the dehumidifying agent and the release of effective hydrogen.

부식생성물은 기계와 장비 등 여러 금속물질에 수분이 접촉되면서 발생 되는데 부식생성물이 발생하게 되면 기계와 장비의 성능이 떨어지고 오작동의 원인이 되므로 부식생성물의 제거를 필요로 하게 되었다.Corrosion products are generated by the contact of water with various metals such as machinery and equipment. When corrosion products are generated, they degrade performance of machinery and equipment and cause malfunctions. Therefore, corrosion products need to be removed.

전술한 원인에 따른 여러 가지 제청방법이 제안되고 있는데 종래에 제청방법으로는 산을 이용한 세정법과 알칼리성분을 이용한 세정법 및 전해질 성분을 이용한 세정법 등이 있다.Various decontamination methods have been proposed according to the above-mentioned causes. Conventionally, decontamination methods include a washing method using an acid, a washing method using an alkali component, and a washing method using an electrolyte component.

그러나, 종래에 개발된 제청제는 대부분 액체형태로 존재하기 때문에 부식생성물이 발생한 부위가 수평면이 아닌 수직면등과 같은 경사가 있는 부위에 발생했을 경우에는 제청제가 보유하고 있는 고유 점성이 있더라도 흘러내림 현상이 발생하여 제청제 도포층이 얇아질 뿐만 아니라 얇아진 제청제 도포층은 쉽게 건조되어 제청효과가 떨어지는 단점이 있었다.However, since the conventionally developed decontamination agents exist mostly in liquid form, when the corrosion product is generated on the inclined part such as a vertical plane instead of a horizontal plane, even if there is an inherent viscosity possessed by the decontamination agent, the phenomenon occurs. As a result, not only the detergent coating layer was thinned, but the thinner detergent coating layer was easily dried and had a disadvantage in that the decontamination effect was lowered.

본 발명은 상기의 문제점을 해결하기 위한 것으로, 본 발명의 목적은 직물부재를 이용해 제청제의 흘러내림을 방지하고, 합성수지 필름을 이용하여 제청제의 건조를 차단함으로 제청제의 효율을 높이는 것이다.The present invention is to solve the above problems, an object of the present invention is to prevent the flow of the decontamination agent using the fabric member, and to increase the efficiency of the decontamination agent by blocking the drying of the decontamination agent using a synthetic resin film.

전술한 본 발명의 목적은, 부식생성물이 형성된 표면상에 직물부재를 부착하는 직물부착단계, 상기 직물부재의 상부면에 제청제를 도포하는 제청제도포단계 및제청제가 도포된 상기 직물의 상부면에 합성수지 필름을 부착하여 덮는 필름형성단계를 포함하는 방법을 통해 달성된다.An object of the present invention described above, the fabric attaching step of attaching the fabric member on the surface on which the corrosion product is formed, the decontamination step for applying a detergent on the upper surface of the fabric member and the upper surface of the fabric is applied It is achieved through a method comprising a film forming step of attaching and covering a synthetic resin film.

본 발명의 바람직한 특징에 따르면, 전술한 직물부재는 천연섬유 또는 합성섬유를 직조하여 형성된다.According to a preferred feature of the present invention, the aforementioned fabric member is formed by weaving natural or synthetic fibers.

본 발명의 더욱 바람직한 특징에 따르면, 전술한 합성수지 필름은 10 내지 100 마이크로미터의 두께로 이루어진다.According to a further preferred feature of the invention, the above-mentioned synthetic resin film is made of a thickness of 10 to 100 micrometers.

또한, 상기 부식생성물(1)이 발생한 부위가 수직면일 경우는 제청제(2)를 도포하고, 제청제(2)가 도포된 부위에 상부면에 직물부재(3)를 부착시키는 방법이 사용되기도 한다.In addition, when the portion where the corrosion product 1 is generated is a vertical plane, a method of applying the dehumidifying agent 2 and attaching the fabric member 3 to the upper surface of the decontaminating agent 2 is applied. do.

전술한 필름형성단계는 제청제(2)가 도포된 직물부재(3)의 상부면에 합성수지필름(4)을 부착하여 덮는 단계로, 10 내지 100 마이크로미터의 두께로 이루어진 합성수지필름(4)이 제청제(2)의 건조나 유효수소의 이탈을 방지해 제청효율을 높여주는 역할을 한다.The above-described film forming step is a step of attaching and covering the synthetic resin film 4 on the upper surface of the fabric member 3 to which the dehumidifying agent (2) is applied, the synthetic resin film (4) made of a thickness of 10 to 100 micrometers Prevents drying of decontamination agent (2) or the release of effective hydrogen plays a role in improving decontamination efficiency.

<실시예 1><Example 1>

피팅(pitting)형태의 부식생성물(1)이 발생한 옥외 평면 금속성구조물(5)을 대상으로 붓을 이용하여 제청제(2)를 도포했는데, 붓으로 제청제(2) 만을 도포했을 경우는 10분 경과 후 표면장력으로 인하여 제청제(1)가 도포된 부위에 끝쪽 부분에서부터 건조되기 시작하여 약 30분 후에 지촉건조(손가락으로 촉감을 느꼈을 때 건조된 느낌)가 되었지만, 전술한 본 발명의 제청방법을 사용했을 경우에는 제청제(2)가 50분 이상 용액상태를 유지했다.The decontamination agent (2) was applied with a brush to the outdoor planar metallic structure (5) where the corrosion product (1) in the form of a fitting was generated. If the decontamination agent (2) was applied with the brush, it was 10 minutes. After the elapse of time, due to the surface tension, the decontamination agent (1) began to dry from the end portion to the area where it was touch-dried (feeling dry when touched by the finger) after about 30 minutes, but the method of the present invention described above When used, the dehumidifier (2) was in solution for at least 50 minutes.

<실시예 2><Example 2>

실시예 1과 동일한 금속성구조물(5)의 수직면에 붓을 이용하여 제청제(2)를 도포했는데, 붓으로 제청제(2) 만을 도포했을 경우는 제청제(2)의 흘러내림 현상이 발생하여, 상부면은 5분 경과시부터 건조가 시작되고, 10분 후에는 전면적으로 완전 건조가 되었으며 부식생성물(1)의 제거율은 약 10% 정도였다.When the decontamination agent 2 was applied to the vertical surface of the same metallic structure 5 as in Example 1 using a brush, but only the decontamination agent 2 was applied with the brush, the decontamination phenomenon of the decontamination agent 2 occurred. The top surface was dried after 5 minutes and completely dried after 10 minutes. The removal rate of corrosion product (1) was about 10%.

그러나, 전술한 본 발명의 제청방법을 사용했을 경우에는 제청제(2)가 도포된 구조물의 상부면에서 하부면으로 흘러내림 현상이 거의 없었고 50분 이상 용액상태를 유지했으며, 부식생성물(1)이 모두 제거되었다.However, in the case of using the above-described decontamination method of the present invention, there was almost no flow down from the upper surface of the structure to which the decontamination agent (2) was applied and remained in solution for at least 50 minutes, and the corrosion product (1) All of this was removed.

전술한 본 발명의 일 실시예에 따른 직물을 이용한 제청방법은 부식생성물(1)이 형성된 표면상에 천연섬유 또는 함성섬유를 직조하여 형성된 직물부재(3)를 부착하는 직물부착단계, 상기 직물부재(3)의 상부면에 물 40~50 중량부, 염산 5~15 중량부, 인산 25~35 중량부, 부식방지제 0.5 중량부, 증점제 2~3 중량부, 유화분산제 2 중량부, 수용성 변성아크릴 10 중량부, N-메틸피롤리돈 2 중량부로 이루어진 제청제(2)를 도포하는 제청제(2)도포단계 및 제청제(2)가 도포된 상기 직물의 상부면에 10 내지 100마이크로미터의 두께를 갖는 합성수지필름(4)을 부착하여 덮는 필름형성단계를 포함하여 이루어진다.In the method of using a fabric according to an embodiment of the present invention described above, a fabric attaching step of attaching a fabric member (3) formed by weaving a natural fiber or a synthetic fiber on a surface on which a corrosion product (1) is formed, the fabric member 40 to 50 parts by weight of water, 5 to 15 parts by weight of hydrochloric acid, 25 to 35 parts by weight of phosphoric acid, 0.5 parts by weight of corrosion inhibitor, 2 to 3 parts by weight of thickener, 2 parts by weight of emulsion dispersant, water-soluble modified acrylic on the upper surface of (3) 10 parts by weight of the decontamination agent (2) coating step of applying the decontamination agent (2) consisting of 2 parts by weight of N-methylpyrrolidone and 10 to 100 micrometers on the upper surface of the fabric to which the decontamination agent (2) is applied. And a film forming step of attaching and covering the synthetic resin film 4 having a thickness.

본 발명에 따른 직물을 이용한 제청방법은 금속표면에 제청제의 도포 상태가 보존되므로 부식생성물의 제거에 필요한 제청제의 양을 유지할 수 있어 제청효율이 탁월해지는 효과를 나타낸다.In the method of using the cloth according to the present invention, since the state of application of the detergent is preserved on the metal surface, the amount of the detergent required for the removal of the corrosion product can be maintained, so that the efficiency of the detergent is excellent.

또한, 합성수지 필름으로 제청제가 도포된 직물부재를 덮게 되면 유효수소의 이탈을 최소화하게 되어 제청제의 성능이 유지되므로, 부식생성물의 제거시간이 단축되는 효과를 나타낸다.In addition, covering the fabric member coated with the dehumidifier with a synthetic resin film minimizes the release of the effective hydrogen to maintain the performance of the dehumidifier, exhibiting the effect of shortening the removal time of the corrosion product.

또한, 직물부재의 접착을 통해 제청제의 흐름과 건조가 최소화되어 재도포 횟수를 줄여주므로 제청비용절감 효과를 나타낸다.In addition, since the flow and drying of the dehumidifying agent is minimized through the adhesion of the fabric member, the number of reapplications is reduced, thereby reducing the decontamination cost.
