Description

양식장용 코팅 강관Aquaculture Coated Steel Pipe

본 고안은 양식장에 사용되는 강관의 외부 및 내부 표면에 각각 폴리에틸렌 및 중방식 도료를 코팅함으로써 방식성 및 내구성이 우수하도록 한 양식장용 강관을 제공하는데 그 목적이 있다.The object of the present invention is to provide a steel pipe for aquaculture farms which is excellent in corrosion resistance and durability by coating polyethylene and heavy anticorrosive paint on the outer and inner surfaces of the steel pipes used in the farm.

본 고안은 해안지역 양식장의 구조재로 사용되는 강관에 관한 것으로, 강관의 내,외부 표면에 코팅을 하여 방식성 및 내구성을 강화시킨 양식장용 코팅 강관에 관한 것이다.The present invention relates to a steel pipe used as a structural member of the coastal farm, and relates to a coated steel pipe for the corrosion resistance and durability by coating the inner and outer surfaces of the steel pipe.

일반적으로 해안지역의 김양식장에서는 양식김의 고정을 위한 구조물에 구조재로써 목재 또는 강관을 사용하고 있다. 목재 빔은 제작이 간단하고 비용이 저렴한 장점이 있으나, 내구성과 강도에 있어 미흡한 관계로 주로 강관이 사용되고 있다.In general, seaweed farms in the coastal region use wood or steel pipes as structural materials for fixing seaweeds. Wood beam has the advantages of simple manufacturing and low cost, but steel pipe is mainly used because of insufficient durability and strength.

하지만 강관은 해수에 의한 부식에 취약한 단점이 있다. 강관의 주성분인 철은 공기중의 산소와 수분 속의 수산기와 반응하면서 수산화철 화합물인 녹(rust)을 형성하며 쉽게 부식된다. 녹 발생은 해수면 바로 밑에서 특히 심하게 일어나는데 녹이 일단 발생하면 강관의 강도가 떨어지고 부식이 계속적으로 진행되므로 구조재로써의 효용성을 상실한다. 이를 방지하기 위해 페인트 막이 널리 사용되나, 습기를 완전히 차단하지는 못하고 피막이 견고하지 못하기 때문에 내구성이 떨어진다.However, steel pipes have the disadvantage of being vulnerable to corrosion by seawater. Iron, the main component of steel pipes, reacts with oxygen in the air and hydroxyl groups in water, forming rust, an iron hydroxide compound, and easily corroded. Rust generation is particularly severe just below sea level. Once rust occurs, the strength of steel pipes decreases and corrosion continues, thus losing its utility as a structural material. To prevent this, a paint film is widely used, but it is not durable because it does not completely block moisture and the film is not firm.

양식장에 사용되는 구조재는 해안지역의 특성상 해수내의 염분과 강한 자외선 복사가 부식을 촉진하므로 강한 방식성을 가질 것이 요구된다.Structural materials used in aquaculture are required to have strong anticorrosive properties due to the nature of the coastal area because salt and strong ultraviolet radiation in seawater promote corrosion.

하지만 이상 살펴본 바와 같이 종래의 강관은 해안지역과 같은 심한 부식환경 하에서 만족할 만한 방식성 및 내구성을 기대하기 어렵다. 이에 따라서 구조재의 빈번한 교체에 따른 비용 상승의 문제가 발생하고 해수내로 녹성분이 해양오염을 가중시키는 결과를 초래한다.However, as discussed above, conventional steel pipes are difficult to expect satisfactory corrosion resistance and durability under severe corrosive environments such as coastal areas. As a result, the cost increase due to frequent replacement of structural materials occurs, and the rust component increases the marine pollution into the seawater.

본 고안은 상기와 같은 문제점을 해결하기 위하여 종래의 강관에 코팅처리를 하여 해수 및 대기, 자외선과 같은 부식환경으로부터 효과적으로 강관을 차단함으로써 강관의 방식성 및 내구성을 높이는데 그 목적이 있다.The present invention is to improve the corrosion resistance and durability of the steel pipe by effectively blocking the steel pipe from the corrosive environment, such as sea water, air, ultraviolet rays by coating the conventional steel pipe to solve the above problems.

본 고안은 상기 목적을 달성하기 위하여 외표면에 폴리에틸렌 코팅을 하고 내표면에는 중방식 도료를 코팅한 새로운 강관을 제공하는 것을 특징으로 한다.The present invention is characterized by providing a new steel pipe coated with a polyethylene coating on the outer surface and coated with a heavy anticorrosive coating in order to achieve the above object.

제2도는 본 고안의 또다른 실시예를 보인 코팅 강관의 횡단면도.Figure 2 is a cross-sectional view of a coated steel pipe showing another embodiment of the present invention.

1 : 강관 2 : 접착제1: steel pipe 2: adhesive

3 : 폴리에틸렌층 4 : 중방식 도료층3: polyethylene layer 4: medium anticorrosive coating layer

5 : 아연 도금층5: galvanized layer

상기 목적을 달성하기 위한 본 고안의 구성 및 작용을 상세히 살펴보면 다음과 같다.Looking at the configuration and operation of the subject innovation for achieving the above object in detail.

제1도에서와 같이 강관(1)의 외표면에 접착재(2)를 도포하고 자외선 차단제를 첨가한 폴리에틸렌층(3)을 그 위에 접착 형성시킨다. 강관(1)의 내표면에는 기술적으로 폴리에틸렌층 형성이 곤란하므로 선박의 외부 방청도료로 사용되는 중방식 도료(4)를 코팅처리한다.As in FIG. 1, the adhesive 2 is applied to the outer surface of the steel pipe 1, and the polyethylene layer 3 to which the sunscreen is added is adhesively formed thereon. Since the inner surface of the steel pipe (1) is technically difficult to form a polyethylene layer is coated with a heavy anticorrosive coating (4) used as an external antirust coating of the vessel.

외면 코팅재인 폴리에틸렌은 에틸렌의 중합체인 고분자 화합물로서 물리적 화학적으로 안정되어 있고 흡수성이 낮으므로 방식성 및 내구성에 있어서 탁월한 특성을 가지고 있다. 또한 표면이 매끄러워 어패류 부착을 방지할 수 있으며 스케일(scale)이 형성되지 않는다.Polyethylene, which is an outer coating material, is a polymer compound that is a polymer of ethylene, and thus has excellent physical and chemical stability and low water absorption. In addition, the smooth surface prevents fish and shells from attaching and does not form scale.

상기 폴리에틸렌층에 자외선 차단제를 첨가함으로써 자외선의 침투를 방지하여 내구성을 높여준다.By adding a sunscreen to the polyethylene layer to prevent the penetration of ultraviolet rays to increase the durability.

내면 코팅재인 중방식 도료는 피도면과의 접착력이 우수한 강인한 도막을 형성하고, 고성능 방청제를 함유하고 있기 때문에 심한 부식환경에도 견딜 수 있는 방청력을 유지한다.Medium coating material, which is an inner coating material, forms a strong coating film with excellent adhesion to the surface to be coated, and contains a high-performance anti-corrosive agent to maintain the rust resistance to withstand severe corrosive environments.

본 고안의 다른 실시예로서, 제2도에서와 같이 강관(1)의 외표면에 전술한 바와 동일하게 자외선 차단제를 첨가한 폴리에틸렌층(3)을 형성하고 내표면에 아연도금층( 5)을 형성한 코팅강관을 예시할 수 있다. 아연도금층은 수분과 접촉시에 철보다 이온화 경향이 큰 강관 표면의 아연이 우선적으로 산화되어 강관을 보호하는 희생방식성을 가지고 있고, 물리적 손상에 대한 저항이 페인트보다 크며, 접근이 어려운 부분도 용이하게 코팅이 가능하기 때문에 종래의 페인트의 대체제로써 비용에 비해서 탁월한 효과를 볼 수 있다.As another embodiment of the present invention, as shown in FIG. 2, the polyethylene layer 3 to which the sunscreen is added is formed on the outer surface of the steel pipe 1 as described above, and the zinc plated layer 5 is formed on the inner surface. One coated steel pipe can be exemplified. The zinc plated layer has a sacrificial anticorrosive property to protect the steel pipe by preferentially oxidizing zinc on the surface of the steel pipe, which is more ionized than iron when in contact with water. Since the coating is possible, it is possible to obtain an excellent effect on the cost as a substitute for the conventional paint.

아연도금 강관은 표면 아연층의 부식에 의해 강관이 보호되므로 도금의 두께에 따라 내구성이 결정된다.Since galvanized steel pipe is protected by corrosion of the surface zinc layer, durability is determined by the thickness of the plating.

이상과 같이 본 고안은 새로운 대체 자재 개발을 위한 과도한 투자없이도 방식성 및 내구성에 있어 우수한 양식장용 구조재를 제공하므로써, 잦은 교체에 따른 인건비 및 자재비 낭비를 감소하여 비용절감 효과를 가져온다. 또한 해양오염에 대한 규제가 강화되는 추세에 있어서, 부식에 의한 오염물질의 배출이 극히 작기 때문에 더욱 유용하게 사용될 수 있다.As described above, the present invention provides an excellent farming structure in corrosion resistance and durability without excessive investment for the development of new alternative materials, resulting in cost savings by reducing labor and material costs caused by frequent replacement. In addition, in the trend of tightening regulations on marine pollution, it is more useful because the emission of pollutants due to corrosion is extremely small.
