상기 열교환기내에 띄엄띄엄 연결되어 있는 고무연결판이 종래의 탈청제에포함되어 있는 구성요소(예: 황산,염산등)에 의해 녹아내리면서 열교환기의 효율이 떨어지거나 사용이 불가능해지는 문제점을 가지고 있었는데, 종래에는 이러한 문제점을 해결하기 위한 탈청제가 제공되지 못하여 상기와 같이 제조되는 탈청제를 어쩔수없이 사용할 수밖에 없었던 것이다.The rubber connecting plate sparsely connected in the heat exchanger was melted by components (for example, sulfuric acid and hydrochloric acid) included in the conventional desorption agent, so that the efficiency of the heat exchanger was reduced or it was impossible to use. In the related art, desorption agents for solving such problems have not been provided, and thus, desorption agents prepared as described above have to be inevitably used.

There have been many inconveniences associated with the use of conventional degreasers, such as shortening the damage to apartment residents.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해, 에리솔빈산나트륨, 규불화소다, 설파민산, 인산, 구연산, 수산, 부식억제제, 물 등을 일정비율로 혼합시킨 탈청제를 제조토록 함으로써, 냉동기 및 열교환기의 스케일을 효과적으로 없애 부식을 방지하고, 열교환기에 포함된 연결고무판에 전혀 영향을 주지 않으면서도 열교환기 자체의 광택을 최대한 살릴수 있도록 하면서 종래에서와 같은 여러가지의 불편함을 해소하려는데 그 목적이 있는 것이다.Therefore, the present invention is to solve the above-mentioned problems, by preparing a desorption agent mixed with sodium erythorbate, sodium silicate, sulfamic acid, phosphoric acid, citric acid, oxalic acid, corrosion inhibitor, water, etc. In order to eliminate the inconveniences of the conventional method, it is possible to effectively prevent the corrosion by removing the scale of the freezer and the heat exchanger and to maximize the gloss of the heat exchanger itself without affecting the connecting rubber plate included in the heat exchanger.

And to prepare a desalting agent that effectively corresponds to the scale of the plate heat exchanger.
이하, 본 발명의 바람직한 일실시예를 보다 구체적인 수치로서 표1을 참조하여 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described with reference to Table 1 as more specific numerical values.
먼저, 교반기에 물을 52∼62kg(백분율로 하였을때 52∼62%의 범위로서 바람직하게는 56kg으로 탈청제의 전체에서 56%를 차지하도록 함이 좋다)을 투입한다.First, 52 to 62 kg of water (percentage is 52 to 62% of the amount, preferably 56 kg) is charged to the stirrer so as to occupy 56% of the total derinsing agent.
그리고, 상기 물이 투입된 교반기에 다시 30∼40kg(백분율로 하였을때 30∼40%의 범위로서 바람직하게는 35kg으로 탈청제의 전체에서 35%를 차지하도록함이 좋다)의 인산과, 2∼12kg(백분율로 하였을때 2∼12%의 범위로서 바람직하게는 7kg으로 탈청제의 전체에서 7%를 차지하도록 함이 좋다)의 구연산 및, 0.05∼0.15kg(백분율로 하였을때 0.05∼0.15%의 범위로서 바람직하게는 0.1kg으로 탈청제의 전체에서 0.1%를 차지하도록 함이 좋다)의 설파민산을 투입한다.And 30 to 40 kg of phosphoric acid (2 to 12 kg) in the range of 30 to 40%, preferably 35 kg to 35% of the total amount of degreasing agent. Citric acid (in the range of 2 to 12%, preferably 7 kg, preferably 7% of the total degreasing agent) and 0.05 to 0.15 kg (percentage) of 0.05 to 0.15% Preferably, 0.1 kg of sulfamic acid is added thereto.
이때, 상기 물, 인산, 구연산, 설파민산이 일정비율로 혼합된 혼합물을 교반기를 통해 약 7∼9시간동안 교반시킨다.At this time, the mixture of water, phosphoric acid, citric acid and sulfamic acid in a constant ratio is stirred for about 7-9 hours through a stirrer.
이후, 상기 교반기에 의해 생성되는 혼합물에 다시 0.05∼0.15kg(백분율로 하였을때 0.05∼0.15%의 범위로서 바람직하게는 0.1kg으로 탈청제의 전체에서 0.1%를 차지하도록 함이 좋다)의 규불화소다와 에리솔빈산나트륨을 각각 동일비율로 하여 투입한 후, 상기 혼합물을 다시 일정시간(약 1시간 정도가 바람직함)동안 교반시켜 화학반응이 일어나도록 한다.Afterwards, the mixture produced by the stirrer is again silized from 0.05 to 0.15 kg (percentage of 0.05 to 0.15%, preferably 0.1 kg to occupy 0.1% of the total derusting agent). After adding soda and sodium erythorbate in equal proportions, the mixture was stirred again for a predetermined time (preferably about 1 hour) to cause a chemical reaction.
그다음, 상기 규불화소다와 에리솔빈산나트륨의 혼합으로 화학반응이 일어나는 혼합물에 0.5∼1.5kg(백분율로 하였을때 0.5∼1.5%의 범위로서 바람직하게는 1kg으로 탈청제의 전체에서 1%를 차지하도록 함이 좋다)의 수산과, 0.07∼1.7kg(백분율로 하였을때 0.07∼1.7%의 범위로서 바람직하게는 0.2kg으로 탈청제의 전체에서 0.2%를 차지하도록 함이 좋다)의 부식억제제를 투입한다.Then, 0.5 to 1.5 kg (percentage of 0.5 to 1.5% of the total amount of the desorption agent, preferably 1 kg, 1% of the total desorption agent) in the mixture where the chemical reaction takes place by mixing the sodium silicate and sodium erythorbate. And a corrosion inhibitor of 0.07 to 1.7 kg (percentage of 0.07 to 1.7%, preferably 0.2 kg to 0.2% of the total derusting agent). .
그리고 상기 수산과 부식억제제가 투입된 혼합물을 다시 일정시간(약 30분정도가 바람직함)동안 교반기를 통해 교반시키면, 냉동기 및 열교환기의 스케일을 효과적으로 없애 부식을 방지하고, 열교환기에 포함된 연결고무판에 전혀 영향을 주지 않으면서도 열교환기 자체의 광택을 최대한 살릴수 있는 탈청제의 제조가 완료되는 것이다.When the mixture of the fish and the corrosion inhibitor is stirred through the stirrer again for a predetermined time (preferably about 30 minutes), the scales of the freezer and the heat exchanger are effectively removed to prevent corrosion, and the joint rubber plate included in the heat exchanger is completely removed. The manufacture of the descavenger that can maximize the gloss of the heat exchanger itself without affecting is completed.
즉, 본 발명의 바람직한 실시예에서 제공하는 탈청제의 구성요소들에 대하여 보다 구체적으로 살펴보면 다음과 같다.That is, the components of the degreasing agent provided in the preferred embodiment of the present invention will be described in more detail as follows.
먼저, 인산과 구연산은 열교환기의 재질로서 사용되는 스텐레스재의 부식을 방지하는 작용을 갖고 있을 뿐만 아니라(여기서 설파민산도 스텐레스재질의 부식을 방지하는 작용을 약간 가지고 있음), 열교환기에 포함된 연결고무판에 아무런 영향을 주지 않으면서도 열교환기의 판(또는 배관)에서 발생하는 스케일을 닦아서 없애주는 작용을 한다.First, phosphoric acid and citric acid not only have a function of preventing corrosion of the stainless material used as the material of the heat exchanger (here sulfamic acid also has a function of preventing the corrosion of the stainless material), and the connecting rubber plate included in the heat exchanger. It cleans and removes the scale generated from the plate (or pipe) of the heat exchanger without affecting it.
여기서, 상기 인산과 구연산은 스텐레스재의 부식방지는 물론 스케일을 닦아내주는 탁월한 작용을 하는 반면, 스텐레스재의 광택을 없애는 단점도 가지고 있는 관계로,Here, while the phosphoric acid and citric acid have an excellent function of preventing the corrosion of the stainless steel material as well as wipe off the scale, it also has the disadvantage of removing the gloss of the stainless steel material,
본 발명에서는 상기 인산과 구연산에 의해 없어지는 광택을 되살릴수 있도록 탈청제에 설파민산과 부식억제제를 첨가 하므로서, 판형 열교환기의 광택을 되살릴수 있도록 한 것이다.In the present invention, by adding sulfamic acid and a corrosion inhibitor to the degreasing agent to restore the luster lost by the phosphoric acid and citric acid, it is possible to restore the luster of the plate heat exchanger.
또한, 상기 탈청제에 포함된 규불화소다와 에리솔빈산나트륨은 판형의 열교환내에서 발생하는 스케일을 열교환기의 판(또는 배관)으로부터 이탈시켜 주는 작용을 하고, 수산은 큰 덩어리의 스케일을 부드럽게 만들어주면서 쉽게 으깨어지도록 하는 작용을 수행하게 되는 바,In addition, the sodium silicate and sodium erythorbate contained in the desorption agent remove the scale generated in the plate heat exchanger from the plate (or pipe) of the heat exchanger, and the oxalic acid smoothes the scale of the large mass. To make it easier to crush,
상기 규불화소다 및 에리솔빈산나트륨과 수산에 의해 이탈되거나 으깨지는 스케일들은 인산과 구연산의 작용으로 부터 용이하게 없어질수 있게 되는 것이다.The scales separated or crushed by the sodium silicate and sodium erythorbate and oxalic acid can be easily removed from the action of phosphoric acid and citric acid.
한편, 상기 에리솔빈산나트륨, 규불화소다, 설파민산, 인산, 구연산, 수산, 부식억제제는 모두 물에 투입되는 바, 이는 물과 상기 각 구성요소들이 서로 쉽게 용해 될수 있도록 하기 위해서이다.On the other hand, the sodium erythorbate, sodium silicate, sulfamic acid, phosphoric acid, citric acid, hydroxyl, corrosion inhibitors are all added to the water, so that the water and each of the components can be easily dissolved with each other.
여기서, 상기 부식억제제는 세제를 겸한 광택 계면 활성제가 섞여있는 부식억제제를 사용함이 바람직하고, 상기 계면 활성제는 중성의 성질을 띠고 있는 것이 바람직하다.Here, it is preferable to use a corrosion inhibitor which is mixed with a bright surfactant such as a detergent, it is preferable that the surfactant has a neutral property.
이상에서 설명한 바와같이 본 발명은 에리솔빈산나트륨, 규불화소다, 설파민산, 인산, 구연산, 수산, 부식억제제, 물 등을 일정비율로 혼합시킨 탈청제를 제조함으로써, 냉동기 또는 열교환기내의 스케일을 효과적으로 없애 부식을 방지하고, 열교환기에 포함된 연결고무판에 전혀 영향을 주지 않으면서도 열교환기 자체의 광택을 최대한 살릴수 있는 효과를 제공한다.As described above, the present invention provides a scale in a refrigerator or a heat exchanger by preparing a desorption agent in which sodium erythorbate, sodium silicate, sulfamic acid, phosphoric acid, citric acid, oxalic acid, corrosion inhibitor, water, and the like are mixed at a predetermined ratio. It effectively eliminates corrosion and provides maximum effect on the gloss of the heat exchanger itself without affecting the connecting rubber plate included in the heat exchanger.
