Description
본 발명은 부식억제 배합물에 관한 것으로서, 보다 상세하게는 냉각수 혹은 난방용의 배관으로 사용되는 금속 및 비철금속의 부식을 억제하기 위한 배합물 및 그 제조방법에 관한 것이다. The present invention relates to a corrosion inhibiting compound, and more particularly, to a compound for suppressing the corrosion of metals and nonferrous metals used as cooling water or a pipe for heating, and a method of manufacturing the same.
일반적으로, 순환식 배관이나 항상 물에 잠겨 있는 용기 등의 경우 그 표면은 금속 혹은 비철금속으로 구성되어 있으므로 부식현상이 발생하거나 스케일이 적층되어 관이 막히는 현상이 일어난다. 이를 해결하기 위한 여러 가지 부식방지제가 개발되어 왔는 바, 지금까지 주요한 부식방지제로서는 인산염, 규산염, 탄산염, 아질산염 등이 사용되어 왔다. In general, in the case of a circulating pipe or a container which is always submerged in water, the surface is made of metal or non-ferrous metal, so that corrosion occurs or scales are stacked to block the pipe. Various corrosion inhibitors have been developed to solve this problem. Until now, the main corrosion inhibitors include phosphates, silicates, carbonates, nitrites, and the like.
상기 규산염의 주성분은 규산메타 나트륨이며, 이를 물에 첨가하면 금속표면에 피막을 형성하며, 탄산칼슘과 결합하여 스케일을 방지한다. 그러나, 고순도의 규산염은 제조원가가 너무 비싸고 또한 단일 규산염의 화학적 기능만으로는 부식방지를 위한 다양한 기능을 기대하기 어렵다는 문제점이 있다. The main component of the silicate is methyl silicate, which is added to water to form a film on the metal surface, and combines with calcium carbonate to prevent scale. However, of high purity Silicate has a problem that the manufacturing cost is too expensive and it is difficult to expect a variety of functions for corrosion protection only by the chemical function of a single silicate.
또한, 인산염계를 주성분으로 하는 부식방지제는 중성의 수질에서만 효과를 기대할 수 있으며, 수질의 수소이온 농도가 5 ~ 6일 경우에는 효과가 떨어지는 단점이 있다. 또한, 구리관에 사용하면 물에 불용성인 피로인산 구리가 생성되어 배관의 수명을 단축시키고, 열교환용 배관 등에 사용할 때 슬라임이 형성되어 열전달 및 순환을 방해할 우려가 있으며, 온수에 사용할 때 방청 성분이 가수분해되어 효과가 떨어지는 문제점이 있다. 즉, 동관이나 구리관에는 적용하기 부적합한 단점이 있다. In addition, the phosphate-based corrosion inhibitors can be expected to effect only in neutral water quality, there is a disadvantage that the effect is less when the hydrogen ion concentration of the water quality is 5-6. In addition, when used in copper pipes, copper pyrophosphate which is insoluble in water is generated, which shortens the life of pipes, and when used in heat exchange pipes, slime is formed, which may interfere with heat transfer and circulation. There is a problem in that the hydrolysis is less effective. That is, there is a disadvantage that is not suitable for applying to copper or copper pipes.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 본 발명의 목적은 건물의 배관시설과 생산라인 수관내부의 부식 및 스케일(scale)을 방지하여 배관보수 유지비를 절감하고 열효율을 증대시키고 작업능률의 향상시킬 수 있는 부식억제 배합물 및 이를 제조하는 방법을 제공하는 것이다. The present invention has been made to solve the above problems, the object of the present invention is to prevent the corrosion and scale in the building piping and production line water pipes to reduce the maintenance cost of pipes and increase the thermal efficiency and work It is to provide a corrosion inhibitor formulation and a method of manufacturing the same that can improve the efficiency.

본 발명에서는 에틸렌디아민테트라아세틱 액시드와 제 3인산나트륨을 일정하게 배합하고 기타 첨가제를 혼합하여 이를 물에 희석하여 사용함으로써 배관 내의 부식 및 스케일을 효율적으로 방지하고자 한다. 즉, 종래의 방식과는 달리 본 발명에서는 칼슘이온, 마그네슘이온, 실리카 등 스케일을 발생시키는 금속성분을 에틸렌디아민테트라아세틱 액시드가 배위결합하는 방식을 적용하였다. In the present invention, ethylenediaminetetraacetic acid and tribasic sodium phosphate are uniformly mixed, and other additives are mixed and diluted in water to use. To prevent corrosion and scale efficiently. That is, unlike the conventional method, in the present invention, a method of coordinating ethylenediaminetetraacetic acid with a metal component that generates scale such as calcium ions, magnesium ions, and silica is applied.
