Abstract
본 발명은 알루미늄 배관의 부식을 방지하기 위한 발포액에 관한 것으로, 보다 상세하게는 고분자 수지에 나트륨이온, 마그네슘이온 및 칼슘이온으로 이루어진 그룹 중에서 선택된 하나 이상을 포함하는 화합물 및 염화이온을 포함하는 화합물이 포함됨으로써, 공기 또는 발포액에 포함된 염화이온이 나트륨이온, 마그네슘이온 및 칼슘이온과 반응하여 알루미늄 배관을 부식시키는 강산이 발생되지 않는다.The present invention relates to a foaming solution for preventing corrosion of aluminum pipes, and more particularly, a compound containing at least one selected from the group consisting of sodium ions, magnesium ions and calcium ions in the polymer resin and a compound containing chloride ions. By this, the chloride acid contained in the air or the foaming liquid does not generate a strong acid that reacts with sodium ions, magnesium ions and calcium ions to corrode the aluminum pipe.

Description
본 발명은 알루미늄 배관에 발포되는 발포액에 관한 것으로서, 상세하게는 염화이온과 반응할 수 있는 나트륨이온, 마그네슘이온 또는 칼슘이온을 포함하는 화합물이 포함된 부식 방지용 발포액에 관한 것이다. The present invention relates to a foam liquid foamed in an aluminum pipe, and more particularly, to a corrosion preventing foam liquid containing a compound containing sodium ions, magnesium ions or calcium ions that can react with chloride ions.
최근에는 김치만을 보관하기 위한 김치전용 냉장고가 개발되어 출시되고 있다. 이러한 김치냉장고는 저장실에 반입된 김치에 적당한 온도를 공급하여 숙성시킨 다음, 적당한 보관온도를 유지하면서 김치를 장기간 보관할 수 있도록 동작하게 된다.Recently, a kimchi refrigerator for storing only kimchi has been developed and released. The kimchi refrigerator is operated to supply kimchi brought into the storage room at an appropriate temperature and to be matured, and then to keep kimchi for a long time while maintaining an appropriate storage temperature.
일반적인 김치냉장고는 도어를 개폐하는 방식으로 저장실에 김치를 반입하거나 반출할 수 있도록 구성되어 있다. 그리고 냉장고 내부에는 김치의 숙성시 적합한 온도를 유지할 수 있도록 열을 발생시키는 히터와, 보관시 일정한 저온상태를 유지하기 위한 냉동사이클을 구현하는 구성요소들이 설치된다.The general kimchi refrigerator is configured to bring in or take out kimchi in the storage room by opening and closing the door. And inside the refrigerator is installed a heater for generating heat so as to maintain a suitable temperature during the ripening of kimchi, and components for implementing a refrigeration cycle for maintaining a constant low temperature during storage.
이러한 김치냉장고에 있어서, 새로 담근 김치가 투입되면 숙성을 위한 적절 한 온도를 제공하는 일련의 숙성과정이 진행되는데, 이러한 숙성과정은 상기 히터의 발열에 의해 김치의 숙성에 적합한 온도를 유지한다.In the kimchi refrigerator, when a new soaked kimchi is added, a series of ripening processes are provided to provide an appropriate temperature for ripening. This ripening process maintains a temperature suitable for ripening of kimchi by the heating of the heater.
상기 과정을 거쳐 김치의 숙성이 완료되면, 상기 냉동사이클 구성요소들이 동작하는 것에 의하여 김치를 보관하는 과정이 진행된다. 이러한 보관과정은 냉동사이클을 이용하여 냉매를 순환시킴으로써 김치의 변질을 방지할 수 있는 적절한 저온상태를 유지하는 과정이다.When the aging of kimchi is completed through the above process, the process of storing kimchi is performed by operating the refrigeration cycle components. This storage process is a process of maintaining an appropriate low temperature state to prevent the deterioration of kimchi by circulating the refrigerant using a refrigeration cycle.
이러한 과정을 거치도록 구성된 김치냉장고는 본체에 단열작용을 하는 발포액이 발포되어 김치냉장고 내부와 외부의 열전달을 차단함으로써 상기 과정이 원활히 일어나도록 한다.Kimchi refrigerator configured to go through this process is foamed to insulate the body is foamed to block the heat transfer inside and outside the kimchi refrigerator so that the process occurs smoothly.
또한 발포액은 일반적으로 알루미늄 배관으로 형성된 열교환기(증발관으로 이루어짐)의 표면에 발포되므로, 알루미늄 배관을 보호하는 역할도 한다. 상기 알루미늄 배관은 표면에 산화피막이 형성되어 배관을 보호하지만 공정 또는 운반 중에 산화피막이 손상되면 표면에 발포체가 형성되더라도 쉽게 알루미늄 배관이 부식되는 문제가 있다.In addition, since the foaming liquid is generally foamed on the surface of a heat exchanger (made of an evaporation tube) formed of aluminum tubing, it also serves to protect aluminum tubing. The aluminum pipe has an oxide film formed on the surface to protect the pipe, but if the oxide film is damaged during the process or transportation, the aluminum pipe is easily corroded even if a foam is formed on the surface.
본 발명의 목적은 발포액에 포함되어 발포과정에서 발생되거나 공기 중에 포함된 염화이온이 물과 반응시 알루미늄 배관이 부식되지 않도록 염화이온과 반응할 수 있는 물질들이 포함된 발포액을 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a foaming liquid containing substances capable of reacting with chloride ions so that the aluminum pipe is not corroded when the chloride ion generated in the foaming liquid or contained in the air reacts with water.
또한 본 발명의 다른 목적은 알루미늄 배관의 표면에 발포되는 발포액을 제공하는데 있다. It is another object of the present invention to provide a foaming solution that is foamed on the surface of an aluminum pipe.
상기 목적을 달성하기 위하여, 본 발명의 발포액은 고분자 수지에 나트륨이온, 마그네슘이온 및 칼슘이온으로 이루어진 그룹 중에서 선택된 하나 이상을 포함하는 화합물을 포함한다. 여기에 염화이온을 포함하는 화합물이 추가로 포함될 수 있다.In order to achieve the above object, the foam of the present invention comprises a compound containing at least one selected from the group consisting of sodium ions, magnesium ions and calcium ions in the polymer resin. It may further include a compound containing chloride ion.
