Description

선박 블록 탑재 조인트 부위 일시 보호 도장재 적용 공법{Corrosion Prevention Method for Hull Erection Joint Area During Ship Construction}Corrosion Prevention Method for Hull Erection Joint Area During Ship Construction}

본 발명은 선박의 건조공정 중 노출되는 부식 환경에서 선체의 소지 및 도막을 보호하기 위한 일시 부식 방지 방안으로, Stripable 도료 혹은 방수접착 Sheet의 적용을 통한 공정 개선에 관한 기술이다.The present invention is a temporary corrosion prevention method for protecting the hull and the coating film in the corrosive environment exposed during the drying process of the ship, a technique for improving the process by applying a stripable paint or waterproof adhesive sheet.

일반적인 선박 건조공정은 가공, 소조립, 대조립, 도장, 선탑재(P.E), 탑재, 도크의장, 진수, 안벽의장, 시운전, 인도 공정으로 이루어지며, 개괄적으로는 선체를 구성하는 각각의 블록(Block)을 육상에서 제조하여 도크로 이동시켜 탑재하는 건조공법을 적용하고 있다.The general shipbuilding process consists of processing, subassembly, control, painting, shipboard (PE), mounting, docking, launching, quayside, commissioning, and delivery.In general, each block constituting the hull ( It is applied to dry process that manufactures block) on land and moves it to dock.

도크에서 블록을 탑재하고 진수한 후 안벽기간에는 카고 탱크(Cargo Tank) 구역, 탑재 조인트 그리고 손상 부위에 대한 검사, 에어 테스트(Air Test), 표면처리 및 도장공정이 진행된다(약 2~3개월 이상 소요됨).After loading and launching the block in the dock, the quay period during the cargo tank area, mounting joints and damage inspection, air test, surface treatment and painting process (about 2-3 months) Above).

그런데, 이 경우 특히 탑재 조인트 부위(도 2)는 선박 인도 시점까지 해수 및 각종 오염 환경에 장기간 노출되어 손상되는 관계로, 선체 조립 완료 후 추가적인 세척, 표면처리 및 재도장 공정을 실시하여야 하는 문제점을 가진다. 더욱이 종래에는 탑재 조인트나 손상부위의 용접 완료 후 일시 방청용 Zinc 도료를 발랐는데, 이는 상기 세척, 표면처리 작업시 Zinc의 잔존으로 인한 표면처리 공수가 증가하는 문제점까지 더불어 유발하고 있는 실정이다(도 3 참조).However, in this case, the mounting joint part (FIG. 2) is damaged due to prolonged exposure to seawater and various polluted environments until the time of delivery of the ship. Have Furthermore, conventionally, after the welding of the mounting joint or the damaged part is completed, a temporary anti-corrosive zinc coating was applied, which also causes a problem of increasing the number of surface treatments due to the remaining zinc during the cleaning and surface treatment operations (FIG. 3).

한편, 부식 방지를 위해 적용하고자 하는 Stripable 도료는 종래 1액형 상온건조 타입의 도료로, 박막 도장시 도막 제거성 불량으로 인한 추가 전처리 작업 실시, 3개월 이상 폭로시 도막 열화로 인한 제거 불량 등 박리 문제점을 드러내고 있으며, 방수 접착 Sheet의 경우도 접착액의 고착으로 인하여 추가 전처리 작업이 필요한 문제점을 가진다.On the other hand, the stripable paint to be applied to prevent corrosion is a conventional one-component room temperature drying type paint, additional pre-treatment work due to poor film removability when coating a thin film, peeling problems such as poor removal due to deterioration of the film when exposed more than 3 months In addition, the waterproof adhesive sheet also has a problem that requires additional pretreatment work due to the adhesion of the adhesive liquid.

본 발명은 종래 탑재 조인트 및 화기 손상 부위의 일시방청용 Zinc 도료 적용 후 안벽기간 동안 이루어지는 표면처리 및 재도장 공정을 단축하기 위하여, 탑재 후 표면처리 완료 후 일시 방청용 Stripable 도료 혹은 방수접착 Sheet의 적용을 통하여 안벽공기를 효과적으로 단축시킬 수 있도록 하는 부식 방지 공법을 제시하는 것을 목적으로 한다.The present invention, in order to shorten the surface treatment and re-painting process performed during the quay wall period after the application of the temporary anti-corrosive zinc coating of the conventional mounting joint and fire damage, the application of the temporary anti-rust stripable paint or waterproof adhesive sheet after the surface treatment after mounting The purpose of the present invention is to propose a corrosion prevention method that can effectively reduce the quay air.

이하, 본 발명의 바람직한 실시예를 첨부된 도면들을 참조하여 상세히 설명한다. 본 발명을 설명함에 있어, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 본 발명의 요지를 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명은 생략한다. 또한, 이하에서 본 발명의 바람직한 실시예를 설명할 것이나, 본 발명의 기술적 사상은 이에 한정하거나 제한되지 않고 당업자에 의해 변형되어 다양하게 실시될 수 있음은 물론이다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the following will describe a preferred embodiment of the present invention, but the technical idea of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

본 발명은 선박 건조공정 중 도크(Dock)에서 이루어지는 세미텐덤 건조공법 및 진수(Launching) 시 방식도장이 실시되지 않은 구역이 해수침적 환경 하에서 부식되는 것을 방지하기 위하여, 방식도장이 실시되지 않은 구역에 일시 보호 도장재를 적용함으로써 선박 건조공정의 단축 및 전처리 비용의 절감이라는 효과를 유도하고자 한다.The present invention is to prevent the corrosion of the semi-tendum drying method in the dock (dock) during the shipbuilding process and the area where the anticorrosive coating is not carried out during launching, to prevent corrosion under seawater deposition environment, By applying the temporary protective coating material, it is intended to induce the effect of shortening the ship construction process and reducing the pretreatment cost.

이를 위하여 본 발명은, 탑재 후 2차 표면처리를 하는 단계; 일시 보호 도장재를 적용하는 단계; 안벽작업을 수행하는 단계; 일시 보호 도장재를 제거하는 단계 및; 재도장을 하는 단계;를 포함하는 선박 블록 탑재 조인트 부위 일시 보호 도장재 적용 공법을 제시한다.To this end, the present invention, the step of the secondary surface treatment after mounting; Applying a temporary protective paint; Performing a quay wall work; Removing the temporary protective coating material; It proposes a method of applying a temporary protective coating material to the ship block mounting joint site, including the step of repainting.

도 1은 본 발명에 따른 공정흐름을 보여주고 있는데, 도 1에 따르면 본 발명에서는 종래와는 달리 탑재 후 2차 표면처리를 먼저 실시한다.1 shows a process flow according to the present invention. According to FIG. 1, unlike the conventional method, secondary surface treatment is first performed after mounting.

2차 표면처리가 완료되면 탑재 조인트 부위에 일시 보호 도장재를 적용한다. 이러한 일시 보호 도장재는 선박 건조기간 중 탑재 조인트 부위의 오염을 방지하는 역할을 하게 된다.Once the secondary surface finishes, a temporary protective coating is applied to the mounting joint. This temporary protective coating material serves to prevent contamination of the mounting joint portion during the ship construction period.

이때 사용되는 일시 보호 도장재로는 Stripable 도료 혹은 방수접착 Sheet인 것이 바람직한데, 이는 종래에 Zinc 도료를 사용하던 것과 차별화된다.The temporary protective coating used at this time is preferably a stripable paint or a waterproof adhesive sheet, which is different from the conventional zinc paint.

한편, Stripable 도료는 내염성이 좋은 러버(Rubber) 타입의 고인장성을 지닌 도료인 것이 바람직하며, 방수접착 Sheet는 최소 3개월 경과 후에도 잔사(접착제의 끈끈한 부분)가 남지 않는 성질을 갖는 것이 바람직하다. 이러한 특징을 갖는 Stripable 도료 혹은 방수접착 Sheet를 적용하면 추후 별도의 전처리 작업을 재수행하지 않아도 되어 좋다.On the other hand, the stripable paint is preferably a rubber (rubber) paint having a high tensile resistance, and the waterproof adhesive sheet preferably has a property that the residue (sticky portion of the adhesive) does not remain after at least 3 months. If you apply Stripable paint or waterproof adhesive sheet with these characteristics, you do not have to perform separate pretreatment work later.

따라서 본 발명에서는 일시 보호 도장재 적용 후 안벽 작업을 거치고 나면, 일시 보호 도장재를 제거하고 별도의 전처리 작업 없이 곧바로 재도장을 할 수 있다. 그리고 이와 같은 과정을 통하여 안벽 공기를 효과적으로 단축시킬 수 있다.
Therefore, in the present invention, after the temporary wall work after applying the temporary protective coating material, it is possible to remove the temporary protective coating material and immediately repaint without additional pretreatment. And through this process it is possible to effectively shorten the wall air.

이상의 설명은 본 발명의 기술 사상을 예시적으로 설명한 것에 불과한 것으로서, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 본 발명의 본질적인 특성에서 벗어나지 않는 범위 내에서 다양한 수정, 변경 및 치환이 가능할 것이다. 따라서 본 발명에 개시된 실시예 및 첨부된 도면들은 본 발명의 기술 사상을 한정하기 위한 것이 아니라 설명하기 위한 것이고, 이러한 실시예 및 첨부된 도면에 의하여 본 발명의 기술 사상의 범위가 한정되는 것은 아니다. 본 발명의 보호 범위는 아래의 청구범위에 의하여 해석되어야 하며, 그와 동등한 범위 내에 있는 모든 기술 사상은 본 발명의 권리범위에 포함되는 것으로 해석되어야 할 것이다.The above description is merely illustrative of the technical idea of the present invention, and various modifications, changes, and substitutions may be made by those skilled in the art without departing from the essential characteristics of the present invention. will be. Accordingly, the embodiments disclosed in the present invention and the accompanying drawings are not intended to limit the technical spirit of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by the embodiments and the accompanying drawings. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.
