Description

핀 튜브용 수용성 방청유{Water-soluble rust-preventive oil for finned tube}{Water-soluble rust-preventive oil for finned tube}

열병합발전소의 배열회수증기발생기(Heat Recovery Steam Generator)나 보일러 등에 사용되는 열교환기는 온도가 다른 2개의 유도체를 직접 또는 간접으로 접촉시켜 열을 교환하게 하는 장치로서, 이러한 산업용 열교환기는 고성능의 전열관이 필요하므로 유체의 접촉면적을 크게 하여 열전달 효율을 극대화하기 위해 튜브 표면에 핀을 접착하여 구성되는데, 이러한 튜브를 핀 튜브(Finned Tube)라고 한다.Heat Recovery Steam Generator A heat exchanger used in a steam generator or boiler is a device that directly or indirectly contacts two different temperature derivatives to exchange heat. Such industrial heat exchangers require high performance heat transfer tubes Therefore, in order to maximize the heat transfer efficiency by increasing the contact area of the fluid, a fin is attached to the surface of the tube. Such a tube is called a finned tube.

본 발명은 위와 같은 핀 튜브 자재에 적용되는 수용성 방청유에 관한 것으로, 더욱 상세하게는 열감량성과 방청성, 그리고 환경친화적 특성을 갖는 수용성 방청유에 관한 것이다.
The present invention relates to a water-soluble anti-corrosive oil to be applied to the above-mentioned fin tube material, and more particularly to a water-soluble anti-corrosive oil having heat loss, rust prevention and environment-friendly characteristics.

핀 튜브의 제작시부터 설치·가동되기까지의 사이에 녹 발생을 방지하기 위해 방청유를 사용한다.Rustproof oil is used to prevent rust from the time of manufacture of the fin tube to installation and operation.

종래에는 유성계 방청유를 적용함으로써 핀 튜브 제작과정 중 방청유 도포과정에서 휘발성 유기용제(VOC'S) 가스 발생, 공장오염 발생, 인체에 유해한 휘발성 유기용제(VOC'S)에의 노출 및 화재 발생 우려와 같은 문제가 있었을 뿐 아니라, 유성계 방청유의 미건조 특성으로 인해 도장 작업성이 좋지 않았고 장기 외부 폭로나 기후 변화에 따라 방청유의 도막이 제거되고 부분적으로 녹이 발생하여 제품의 품질 저하를 초래하는 단점이 있었다.Conventionally, there have been problems such as generation of volatile organic solvent (VOC'S) gas, occurrence of factory pollution, exposure to volatile organic solvent (VOC'S) harmful to human body and fear of fire in the process of applying rust preventive oil during fin tube manufacturing process In addition, there is a disadvantage in that the paint workability is poor due to the non-drying characteristics of oil-based rust-preventive oil, the coating film of rust-preventive oil is removed due to long-term external weathering or climate change,

또한 열교환기의 핀 튜브에 적용되는 방청유는 설비의 제작에서 설치·가동 전까지 방청성을 발휘하여야 함은 물론, 핀 튜브의 열전달 효율을 극대화하기 위하여 설비 가동시 생성되는 200℃의 자체 열에 의해 50% 이상, 300℃의 자체 열에 의해 80% 이상 분해 제거되어야 한다는 요구를 동시에 만족시켜야 한다(만약 가동 후에도 방청유가 분해 제거되지 않을 경우 핀 튜브의 열전달 효율이 떨어지는 문제가 발생할 수 있다).In addition, the anti-rust oil applied to the fin tube of the heat exchanger must exhibit rustproofing before installation and operation of the facility, and it is necessary to increase the heat transfer efficiency of the fin tube by 50% or more , And at least 80% by the own heat of 300 ° C. (If the anti-rust oil is not decomposed and removed even after the operation, the heat transfer efficiency of the fin tube may be lowered).

그런데 현재까지 소개된 방청유는 방청성이 불량하거나, 열에 의해 분해 제거되는 기능이 저하되는 문제를 안고 있었다. 따라서 열에 의해 분해 제거되는 열감량성과 방청성이 우수한 수용성 방청유 개발이 요구되어 왔다. 이 수용성 방청유는 휘발성 유기용제(VOC'S) 규제에 적합하고 인체에 무해하며 중금속이 없는 친환경적 특성을 갖는 게 바람직하다.
However, the rust preventive oil introduced to date has a problem that the rustproofing property is poor or the function of decomposing and removing by heat is deteriorated. Therefore, development of a water-soluble anti-corrosive oil excellent in heat loss and heat resistance and excellent in rust prevention has been demanded. It is preferable that the water-soluble anti-corrosive oil is environmentally friendly, which is suitable for the regulation of volatile organic solvent (VOC'S), is harmless to the human body, and has no heavy metal.

본 발명은 상기와 같은 문제를 해결하기 위한 것으로, 열감량성과 방청성이 우수하고 냄새와 중금속이 없는 핀 튜브용 수용성 방청유를 제공하는 데 그 목적이 있다.An object of the present invention is to provide a water-soluble anti-corrosive oil for fin tubes which is excellent in heat loss and corrosion resistance and has no odor and heavy metal.

상기 수용성 방청유에서 2종 수지의 함량별 시험 중 열에 분해, 제거되는 성능에 있어서 수용성 아크릴 수지 함량이 수용성 알키드 수지 함량보다 2~3배 많게 하는 것이 바람직하다. 수용성 알키드 수지 성분이 많이 존재할 경우 건조 속도가 느리게 되며 표면에 Tack가 많이 남을 수 있으며 알키드 성분은 수용화가 아크릴 수지에 비해 잘되지 않아 사용상의 어려점이 있으므로 아크릴 수지와 알키드 수지의 성분을 적당히 조절하여 사용하여야 한다.
It is preferable that the content of the water-soluble acrylic resin is 2 to 3 times as much as the content of the water-soluble alkyd resin in the performance of decomposition and removal of the water in the water-soluble anti-corrosive oil. If there is a large amount of water-soluble alkyd resin component, the drying speed is slow and there may be a lot of tack on the surface. Since the alkyd component is not better than acrylic resin because of its difficulty in use, it is necessary to control the components of acrylic resin and alkyd resin shall.

상기 수용성 알키드 수지는 상기 수용성 아크릴 수지와 같이 도막을 형성하는 주요 물질로 부착성, 작업성 등을 결정하는 역할을 한다. The water-soluble alkyd resin is a main material for forming a coating film like the water-soluble acrylic resin, and plays a role in determining adhesion, workability and the like.

The water-soluble alkyd resin is synthesized by using anhydrous trimeric acid for water-solubilization and is synthesized so that the acid value becomes 40 to 70 mg KOH / g so as to facilitate the water-soluble alkyd resin. If the acid value is too low, the water is not well - hydrated. If the acid value is too high, the water is easily hydrolyzed.
