Description
본 발명은 규산염 청관제 및 그 제조방법에 관한 것으로, 보다 상세하게는 산화나트륨 대비 이산화규소의 몰비가 다른 두 종류의 규산나트륨 수용액을 주성분으로, 알칼리금속염과 점도조절제 및 계면활성제를 첨가함으로서 환경 무해화를 효과적으로 달성하고, 생산성 및 경제적 측면에서 효율적으로 처리가 가능할 수 있도록 하는 것을 특징으로 하는 규산염 청관제 및 그 제조방법에 관한 것이다.The present invention relates to a silicate cleansing agent and a method for producing the same, and more particularly, to two types of sodium silicate aqueous solutions having different molar ratios of silicon dioxide to sodium oxide as a main component, by adding an alkali metal salt, a viscosity modifier, and a surfactant to harm the environment. The present invention relates to a silicate cleaning agent and a method for producing the same, which can be effectively achieved and can be efficiently processed in terms of productivity and economics.
종래의 보일러,냉각수배관 및 각종 배관은 노화 되거나 장기간 방치할 경우, 배관의 관내부가 용존산소에 의하여 부식되고, 용수에 포함된 경도성분과 유기물 및 약품에 의한 관내에 관석이 형성되어 각종 배관의 열효율 저하 및 파열 등의 문제점이 초래되고 있다.In conventional boilers, cooling water pipes, and various pipes, if they are aged or left for a long time, the inside of the pipes are corroded by dissolved oxygen, and the capstone is formed in the pipes by the hardness components, organic substances, and chemicals contained in the water. Problems such as degradation and rupture have been brought about.
따라서 이를 해결하기 위해, 인산염이 포함된 청관제가 사용되고 있으나, 이러한 종래의 인산염 청관제는 배관내의 인산염이 물과 반응하여 가수분해 되면서 알칼리금속을 석출하기 때문에, 관내의 부식 및 불용성 인산 착염의 형성으로 관석이 발생하여 열효율을 저하시킨다. 또한, 인산염이 물에 다량으로 용해되어 하천이나 강물로 배출되면 녹조 및 적조 현상이 발생하여 산소 결핍으로 인한 부영양화가 발생되는 문제점이 초래된다.Therefore, in order to solve this problem, a rust salt-containing clearing agent is used, but such a conventional phosphate clearing agent precipitates alkali metals as the phosphate in the pipe reacts with water and hydrolyzes, thus causing corrosion and insoluble phosphate complexes in the pipe. This occurs and lowers the thermal efficiency. In addition, when phosphate is dissolved in a large amount in water and discharged into rivers or rivers, green algae and red tide may occur, causing eutrophication due to oxygen deficiency.
본 발명은 상기와 같은 문제점을 해결코자 하는 것으로, 본 발명의 목적은, 환경오염을 유발하는 인산 및 인산염을 포함하지 않은 청관제 및 그 제조방법으로서, 산화나트륨 대비 이산화규소의 몰비가 다른 두 종류의 규산나트륨 수용액과 알칼리금속염인 수산화나트륨, 점도조절제 및 계면활성제를 혼합 및 교반되는 것으로, 인산염으로 인한 하천과 강물의 부영향화와 각종 배관의 열효율 저하 및 파열를 근본적으로 해결할 수 있는 규산염 청관제 및 그 제조방법을 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention, a cleansing agent that does not contain phosphoric acid and phosphate to cause environmental pollution, and a method for producing the same, two types of silicon dioxide and silicon dioxide different in molar ratio Silicate cleaning agent which can fundamentally solve the side effect of rivers and rivers caused by phosphate and the thermal efficiency decrease and rupture of various pipes by mixing and stirring sodium silicate aqueous solution and alkali metal salt sodium hydroxide, viscosity regulator and surfactant.

이하에서 본 발명의 바람직한 실시예를 첨부하여 도면에 의거 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
도 1은 본 발명의 일시예에 따른 규산염 청관제의 제조방법을 나타내는 흐름도이다. 도 1에 도시된 바와 같이, 본 발명의 제 1 규산나트륨 수용액 준비공정(S10a)은 산화나트륨 대비 이산화규소의 몰비를 다르게 하여 혼합 및 교반한다. 여기서 청관제의 무게비에 따른 비율은 30∼60wt%으로 하는 것이 가장 적당하며, 30%미만 및 60%이상일 경우에는 철 시편의 일부가 부식이 발생되는 역효과가 발생한다.1 is a flow chart showing a method for producing a silicate cleaning agent according to one embodiment of the present invention. As shown in Figure 1, the first sodium silicate aqueous solution preparation process (S10a) of the present invention is mixed and stirred by varying the molar ratio of silicon dioxide to sodium oxide. The ratio according to the weight ratio of the cleansing agent is most suitable to 30 ~ 60wt%, and less than 30% and more than 60%, the adverse effect of the corrosion of some of the iron specimen occurs.

If it is more than 70%, the viscosity is high, and productivity and corrosion protection are greatly reduced. And, the alkali metal salt mixed and stirred in the second sodium silicate aqueous solution is preferably used as sodium hydroxide, the weight ratio of the alkali metal salt is 0.9 to 5wt% and less than 0.9% when corrosion occurs and more than 5% The corrosion gradually occurs after 30 days.
또한 상기 점도조절제는 1∼10wt%로 청관제의 농도와 비중을 적절하게 조절하며, 상기 계면활성제는 0∼5wt%의 비율로 청관제의 액체 표면에 흡착되어 계면의 활성을 돕는다. 이때 5wt%이상 초과할 경우에는 용해도가 감소하는 결과가 나타나므로 0.1∼2wt%가 가장 효과적이다.In addition, the viscosity modifier to suitably adjust the concentration and specific gravity of the clarifier to 1 to 10wt%, the surfactant is adsorbed on the liquid surface of the clarifier in the ratio of 0 to 5wt% to help the activity of the interface. At this time, when it exceeds 5wt%, solubility decreases, so 0.1 ~ 2wt% is most effective.
상기 규산염 청관제 준비공정(S20)은 제 1 규산나트륨 수용액과 제 3 규산나트륨 수용액의 혼합물인 제 2 규산나트륨 수용액, 알칼리금속염, 점도조절제 및 계면활성제와 함께 1∼3시간 동안 균일하게 혼합하여 투명한 액상 청관제를 얻을수 있다.The silicate cleaning agent preparation step (S20) is a transparent liquid by uniformly mixing for 1 to 3 hours with a second sodium silicate solution, an alkali metal salt, a viscosity modifier and a surfactant, which is a mixture of the first sodium silicate solution and the third sodium silicate solution. You can get a clearing system.
이상에서 설명한 본 발명의 실시예들에서 상기 알칼리금속염은 상기 수산화나트륨, 수산화칼슘, 탄산나트륨 및 탄산칼륨에서 임의로 선택하여 사용할 수 있으며, 가장 바람직하게 사용되는 것은 수산화나트륨이다.In the embodiments of the present invention described above, the alkali metal salt may be arbitrarily selected from sodium hydroxide, calcium hydroxide, sodium carbonate and potassium carbonate, and most preferably used is sodium hydroxide.
(실시예)(Example)
본 발명과 종래의 청관제에 대한 농도별(0.4%,0.5%,0.6%)로 적용한 결과 부식정도의 특성은 다음과 같다.As a result of applying the concentration according to the present invention and the conventional cleansing agent (0.4%, 0.5%, 0.6%), the degree of corrosion is as follows.
×: 부식발생, △: 일부 부식 발생, ○: 침지전,후 변화없음.×: corrosion occurs, △: partial corrosion occurs, ○: no change before or after immersion.
이상에서 상술한 바와같이 본 발명에 따른 규산염 청관제 및 그 제조방법에 의하면, 인산염을 포함하지 않는 제 1 규산나트륨 수용액과 제 3 규산나트륨 수용액을 혼합 및 교반함으로서, 배관의 파열 및 열 효율 저하와 녹조 및 적조로 인한 부영양화의 발생을 방지할 수 있다.As described above, according to the silicate cleansing agent according to the present invention and a method for manufacturing the same, the bursting and thermal efficiency of the pipe and the green algae are reduced by mixing and stirring the first sodium silicate solution and the third sodium silicate solution containing no phosphate. And it can prevent the occurrence of eutrophication due to red tide.
이러한, 본 발명에 의한 규산염 청관제 및 그 제조방법은 생산공정이 간단하고 생산성과 경제적 측면을 효율적으로 이끌어 낼수 있으며, 인산염 청관재로 인한 환경오염을 획기적으로 줄일 수 있는 환경 친화적인 특징을 가지고 있다.Such, the silicate cleansing agent according to the present invention and the manufacturing method thereof is a simple production process, can effectively lead to productivity and economic aspects, and has an environmentally friendly feature that can significantly reduce the environmental pollution caused by phosphate cleansing material.
비록, 본 발명이 상기에서 언급한 바람직한 실시예와 관련하여 설명되어 졌지만, 본 발명의 요지와 범위로 부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능할 것이다. 따라서, 첨부된 청구의 범위는 본 발명의 진정한 범위내에 속하는그러한 수정 및 변형을 포함할 것이라고 여겨진다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, various other modifications and variations may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
