Description

석회제거제 및 그 제조방법{Calcium carbonate remover and making method thereof}Calcium carbonate remover and making method

본 발명은, 석회제거제 및 그 제조방법에 관한 것으로, 보다 상세하게는 백화현상에 따라 해안가를 뒤덮는 석회조류를 제거하는 석회제거제 및 그 제조방법에 관한 것이다.The present invention relates to a descaling agent and a method for manufacturing the same, and more particularly, to a descaling agent for removing the lime algae covering the coastal area according to the whitening phenomenon and a manufacturing method thereof.

최근 연해안에 발생된 백화현상으로 인해 해안생태계가 크게 위협을 받고 있다. 백화현상이란 연해안의 바위표면에 백색 불용화물질이 부착되어 해안을 사막화시키고 바다식물의 생장을 막으며, 플랑크톤의 증식을 억제하여 어패류의 먹이를 고갈시키는 환경파괴현상이다.Recently, coastal ecosystems are threatened by bleaching occurring on the coast. Whitening phenomenon is an environmental destruction phenomenon that white insoluble matter is attached to the rock surface of coastal coast, deserts the coast, prevents the growth of sea plants, suppresses the growth of plankton, and depletes the food of fish and shellfish.

백화현상의 주 원인을 살펴보면 다음과 같다. 바다 속 혹은 연안의 유기물, 즉 탄수화물, 지방질, 단백질 등이 분해되면 CO2가 발생되는 바, 그 반응식은 다음과 같다.The main causes of whitening are as follows. CO 2 is generated when organic matters in the sea or the coast, that is, carbohydrates, fats and proteins, are decomposed. The reaction formula is as follows.

Rl(O)m(OH)n⇒ CH4+ CO2+ (H2O)Rl (O) m (OH) n ⇒ CH 4 + CO 2 + (H 2 O)

ROH, RCOOH ⇒ CH4+ CO2+ (H2O)ROH, RCOOH ⇒ CH 4 + CO 2 + (H 2 O)

RNHCOOH, RR'NCOOH ⇒ NH3+ CH4+ CO2+ (H20)RNHCOOH, RR'NCOOH ⇒ NH 3 + CH 4 + CO 2 + (H 2 0)

발생된 CO2는 바닷물과 반응하여 다음과 같이 H2CO3(탄산)을 생성시킨다.The generated CO 2 reacts with sea water to produce H 2 CO 3 (carbonic acid) as follows.

CO2+ H2O ⇒ H2CO3 CO 2 + H 2 O ⇒ H 2 CO 3

한편, 동해안 주변에 다수 분포되어 있는 석회광산에서 다량 유입되는 생석회(CaO) 또한 바닷물과 반응하여 소석회(Ca(OH)2)가 생성되는 바, 그 반응식은 다음과 같다.On the other hand, calcareous lime (CaO), which is introduced in large quantities in limestone mines distributed around the east coast, also reacts with seawater to produce hydrated lime (Ca (OH) 2 ). The reaction formula is as follows.

CaO + H2O ⇒ Ca(OH)2 CaO + H 2 O ⇒ Ca (OH) 2

소석회는, 전술한 바와 같이 유기물이 분해되면서 발생된 이산화탄소가 바닷물과 반응하여 생성된 탄산과 결합하여 다음과 같이 석회(CaCO3)가 생성된다.Slaked lime, as described above, combines carbon dioxide generated by decomposing organic matter with carbonic acid generated by reaction with seawater to generate lime (CaCO 3 ) as follows.

H2CO3+ Ca(OH)2⇒ CaCO3+ H2OH 2 CO 3 + Ca (OH) 2 ⇒ CaCO 3 + H 2 O

더불어, 난류를 따라 혹은 수온상승에 의해 이상번식한 석회성분으로 이루어진 조식(藻食)동물 또한 석회의 공급원으로 작용한다.In addition, breakfast animals consisting of lime components propagated abnormally along the turbulence or by the rise in water temperature also serve as a source of lime.

한편, 바다 속에 서식하고 있는 미역, 다시마 등 해조류에는 접착성이 강한 알긴산이 다량 함유되어 있다. 지구온난화현상에 따라 수온이 높이지고 난류가 지속적으로 유입되는 지역은 수온이 더욱 올라가게 되어 해조류가 녹아내리게 된다. 이에 알긴산이 바위표면 등에 광범위하게 퍼지게 된다.On the other hand, seaweeds such as seaweed and kelp inhabiting the sea contain a large amount of alginic acid with strong adhesion. According to the global warming phenomenon, the altitude of the algae will melt because the water temperature rises and the turbulent flow continuously increases. As a result, alginic acid spreads widely on rocky surfaces.

바위표면에 퍼져있는 알긴산은 접착제역할을 하여 석회가 바위표면에 더욱 용이하게 부착되도록 하며, 부착량이 많아지면서 석고화현상이 진행되어 백화현상이 나타나게 되는 것이다.Alginic acid spreads on the surface of the rock to act as an adhesive so that lime is more easily attached to the surface of the rock, and as the amount of adhesion increases, gypsumization progresses and whitening occurs.

수온상승으로 인해 해조류가 고갈되면 유기물의 분해과정에서 생성된 CO2의 소비자가 줄어드는 셈이 되어 CO2는 결국 대기중으로 올라가 지구온난화현상을 가속화시키게 된다. CO2일부는 대기 중에서 수증기와 결합하여 탄산(H2CO3)을 생성하며 산성비로서 다시 대지에 공급되기도 한다.When the algae are depleted due to the rise in water temperature, the consumer of CO 2 generated during the decomposition of organic matters decreases, and CO 2 eventually rises to the atmosphere, accelerating global warming. Part of the CO 2 combines with water vapor in the atmosphere to produce carbonic acid (H 2 CO 3 ), which is also supplied back to the earth as acid rain.

종래 백화현상을 퇴치하게 위해서는 사람이 직접 백화된 바위를 쇠줄 등으로 닦아 바위 위에 단단하게 부착된 석회질을 제거하거나 혹은 백화되지 않은 부분이 겉으로 드러나도록 바위를 뒤집어주거나, 폭파 등으로 백화된 바위를 제거하는 등의 방법을 사용하였다.In order to combat the conventional whitening phenomena, a person directly wipes the whitened rock with an iron wire to remove the lime attached firmly to the rock, or turns the rock upside down so that the unwhitened part is exposed, or removes the whitened rock by blasting. And the like method was used.

그러나, 이와 같은 종래 방법은 인력과 경비가 다대히 소요되는 문제점이 있다.However, such a conventional method has a problem in that a large amount of manpower and expenses are required.

따라서, 본 발명의 목적은, 석회질을 용이하게 제거할 수 있는 석회제거제 및 그 제조방법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a descaling agent capable of easily removing calcification and a method for producing the same.

한편 본 발명의 다른 분야에 따르면 상기 목적은, 석회제거제에 있어서, 석회제거제에 있어서, 1 내지 10퍼센트의 키토산; 상기 키토산을 양이온화시키기 위해 투입된 산; 5 내지 10퍼센트의 금속봉쇄제를 포함하는 수용액인 것을 특징으로 하는 석회제거제에 의해서도 달성된다.Meanwhile, according to another field of the present invention, the above object is, in the descaling agent, in the descaling agent, 1 to 10 percent chitosan; Acid introduced to cation the chitosan; It is also achieved with a descaling agent, characterized in that it is an aqueous solution containing 5 to 10 percent metal sequestrant.

여기서, 식물영양제를 더 포함하는 것이 바람직하며, 상기 산은 염산과 아세트산 중 어느 하나인 것이 효과적이다.Here, it is preferable to further include a phytonutrient, and it is effective that the acid is any one of hydrochloric acid and acetic acid.

본 발명에 따른 석회제거제는, 전술한 백화현상에 의해 생성된 석회질을 제거하기 위해 먼저 바위표면 등에 부착된 석회(CaCO3)를 제거하고 필요에 따라 알긴산을 제거하여 제거된 알긴산이 식물영양제 혹은 어패류의 영양제로서 활용될 수 있도록 하며, 바닷물속에 직접 뿌려지므로 무공해물질인 것이 요구된다.Deliming agent according to the present invention, in order to remove the calcification produced by the above-mentioned whitening phenomenon, first remove the lime (CaCO 3 ) attached to the rock surface and the like, alginic acid removed by removing alginic acid if necessary plant nutrients or shellfish It can be used as a nutritional supplement for water, and it is required to be pollution-free because it is sprayed directly into seawater.

본 발명에 따른 석회제거제의 원료물질인 키토산은 건강보조식품으로 사용되기도 하는 무공해물질이며 양이온물질로서, 주로 알긴산소다로서 존재하는 음이온물질인 알긴산과 결합하여 알긴산을 제거하는 역할을 한다. 본 발명에 따른 석회제거제의 다른 원료물질인 DTPA, EDPA, STPP 등은 킬레이트화합물로서 의학적으로 혈액응고방지제로 사용되기도 하는 무공해물질로서, 발열반응에 의해 칼슘(Ca)과 결합됨으로써 칼슘(Ca)을 제거하는 역할을 한다.Chitosan, a raw material of the descaling agent according to the present invention, is a pollution-free material which is also used as a health supplement, and is a cationic material, and serves to remove alginic acid by combining with alginic acid, which is an anionic material mainly present as sodium alginate. DTPA, EDPA, STPP, etc., other raw materials of the descaling agent according to the present invention, are chelating compounds, which are also used as medical anticoagulants for medical purposes, and are combined with calcium (Ca) by exothermic reactions. It serves to remove.

이하에서는 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail.

본 발명에 따른 석회제거제를 제조하는 과정은 다음과 같다. 특별히 언급하지 않은 경우의 모든 과정은 상온의 대기압 하에서 행해진다. 그러나 본 발명에 따른 석회제거제의 제조에 있어 온도와 압력은 발명의 성립성에 영향을 미치지 않으므로, 필요에 따라 압력과 온도를 변화시킨 상태에서 행할 수 있다.The process of preparing the descaling agent according to the present invention is as follows. Unless otherwise noted, all procedures are performed under atmospheric pressure at room temperature. However, in the preparation of the descaling agent according to the present invention, since temperature and pressure do not affect the integrity of the invention, it can be carried out in a state where the pressure and temperature are changed as necessary.

먼저, 물에 키토산(chitosan) 파우더를 넣고 교반한다. 이때 물에 대한 키토산의 농도는 1% 에서 10%정도가 적당하다. 상기 농도는 필요에 따라 조정할 수 있다. 키토산은 키틴(chitin)을 고온으로 알칼리처리한 탈아세틸화합물이다. 키틴은 당의 아미노유도체(아미노당)로 이루어진 N-아세틸-D-글루코사민이 β-1,4결합으로 중합체로서 자연계에서는 셀룰로오스 다음으로 많이 분포하는 다당류로서, 게, 새우 등에 다량 함유되어 있다. 본 발명에서 사용되는 키토산은 식품으로 사용되는 것이 아니므로 순도, 분자량의 크기 및 탈아세틸화의 정도에 특별한 제한을 갖지 않는다.First, chitosan (chitosan) powder in water and stirred. At this time, the concentration of chitosan in water is suitable about 1% to 10%. The said concentration can be adjusted as needed. Chitosan is a deacetyl compound obtained by alkali treatment of chitin at high temperature. Chitin is a polysaccharide in which N-acetyl-D-glucosamine composed of sugar amino derivatives (amino sugars) is a polymer with β-1,4 bonds, and is widely distributed next to cellulose in nature, and is contained in large amounts in crabs, shrimps, and the like. Chitosan used in the present invention is not used as a food, so there is no particular limitation on purity, size of molecular weight and degree of deacetylation.

키토산은 물에 쉽게 용해되지 않으므로 물의 온도를 높여 용해도를 높여주거나, 산을 투입하여 교반해 줌으로써 키토산을 양이온(cation)화시켜 완전히 용해되도록 한다. 여기서, 산은 키토산을 양이온화할 수 있는 산이면 사용가능하며 특히 바람직하기로는 염산과 아세트산을 들 수 있다.Since chitosan is not easily dissolved in water, the solubility is increased by increasing the temperature of the water, or by stirring with an acid, the chitosan is cationic to be completely dissolved. Here, the acid can be used as long as it is an acid capable of cationic chitosan, and particularly preferably hydrochloric acid and acetic acid.

한편, 본 발명에 따른 석회제거제는 석회분해를 위해 금속봉쇄제를 함유하므로, 별개의 반응조에 금속봉쇄제를 넣고 산을 넣어 pH가 6.0 내지 6.5가 되도록 한 후 이를 상기 키토산수용액에 투입하여 금속봉쇄제가 5내지 10퍼센트 함유되도록 한다. 만약 금속봉쇄제에 산을 넣어 용액의 산도를 약산으로 만들어주는 상기 과정을 거치지 않은 채 금속봉쇄제를 그대로 투입하면 알칼리성을 띠는 금속봉쇄제는 키토산과 산알칼리반응을 일으키게 되고 이에 키토산이 재석출되게 된다. 따라서, 금속봉쇄제를 넣을 경우 먼저 산을 투입하여 pH를 맞춘 후, 즉 약산성으로 액성을 바꿔준 후에 투입하여야 한다.On the other hand, since the descaling agent according to the present invention contains a metal blocker for calcification, put a metal blocker in a separate reaction tank to put an acid so that the pH is 6.0 to 6.5 and then put it in the chitosan aqueous solution to block the metal Make sure I have 5 to 10 percent. If the metal blocking agent is added as it is without the above process of adding acid to the metal blocking agent to make the acidity of the solution weak, the alkaline metal blocking agent causes an acid alkali reaction with the chitosan. Will be. Therefore, when the metal blocker is added, the acid must be added first to adjust the pH, that is, after changing the liquidity to weak acidity.

여기서, 금속봉쇄제는 치환반응을 통해 석회에 포함되어 있는 칼슘과 결합함으로써 석회를 분해시키는 역할을 하는 바, EDTA(Ethylene Diamine Tetraacetic Acid), DTPA(Diethylene Triamine Pentaacetic Acid) 및 STPP(Sodium Tri PolyPhosphate)를 들 수 있다.Here, the metal blocker plays a role of decomposing lime by combining with calcium contained in lime through a substitution reaction, such as EDTA (Ethylene Diamine Tetraacetic Acid), DTPA (Diethylene Triamine Pentaacetic Acid) and STPP (Sodium Tri PolyPhosphate) Can be mentioned.

다음으로, 식물영양제를 투입한다. 식물영양제란 해초류 등 바다생물의 생육에 필요한 성분을 총칭하는 것으로, 철(Fe), 망간(Mn), 아연(Zn), 구리(Cu), 몰리브덴(Mo), 붕소(B) 등을 의미한다. 식물영양제는 석회가 제거되고난 뒤, 바위에 다시 유용한 감태류 등이 서식하도록 하기 위한 촉진제 역할을 하게 된다. 다시 말해, 식물영양제를 넣지 않더라도 석회를 제거하는 본 발명의 목적은 달성되지만 식물영양제를 넣을 경우 유용한 조류의 번식을 도와줌으로서 백화현상을 퇴치하기위한 궁극적인 목적달성을 촉진시키는 효과를 가져온다.Next, a phytonutrient is added. Plant nutrient refers to the components necessary for the growth of sea life such as seaweeds, and means iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), boron (B) and the like. . Phytonutrients serve as accelerators for the reusability of Ecklonia cava on the rocks after lime is removed. In other words, the purpose of the present invention to remove the lime without adding the plant nutrients is achieved, but when the plant nutrients are added to help the breeding of useful algae brings the effect of promoting the ultimate goal to combat the whitening phenomenon.

이와 같은 과정에 의해 제조된 석회제거제는 담황색을 띄는 산성액이다.The descaling agent prepared by this process is a pale yellow acid solution.

본 발명에 따른 석회제거제를 사용하여 백화현상으로 인해 해안의 바위표면에 부착된 석회질을 제거하는 과정은 다음과 같다. 본 발명에 다른 석회제거제를 원액 그대로 혹은 필요에 따라 희석시켜 잠수펌프를 사용해 해안의 바위에 살포하면, 석회제거제에 양이온상태로 함유되어 있는 키토산 성분이 석회의 Ca과 응집현상을 일으킴으로써 석회를 분해시키며 알긴산과 결합하여 알긴산을 제거한다. 또한 금속봉쇄제는 치환반응을 통해 석회의 Ca과 결합함으로써 석회를 분해시킨다. 이에 따라 바위표면에 부착되어 있는 석회성분과 알긴산이 분해제거되게 된다.Using the descaling agent according to the present invention to remove the calcification attached to the rock surface of the coast due to whitening is as follows. Diluting the descaling agent according to the present invention as it is or diluting as necessary, and spraying it on the rocks of the coast using a submersible pump, the chitosan component contained in the cationic state of the descaling agent causes the coagulation phenomenon of the lime and decomposes the lime. It combines with alginic acid to remove alginic acid. In addition, the metal blocker decomposes the lime by binding to Ca of the lime through a substitution reaction. As a result, the lime component and alginic acid attached to the rock surface are decomposed and removed.

한편, 식물영양제와 제거된 알긴산은 석회가 제거되고 난 뒤 바다생물의 서식에 유용한 해조류 및 플랑크톤의 양분역할을 하게 된다.On the other hand, phytonutrients and alginic acid are removed, after lime is removed, they serve as nutrients for algae and plankton, which are useful for inhabiting sea life.

더욱이, 본 석회제거제 성분의 하나인 키토산은 생분해성이 매우 뛰어나므로 유기질비료화되어 해조류 및 플랑크톤의 성장에 도움을 준다.Moreover, chitosan, which is one of the components of the descaling agent, is very biodegradable and thus organically fertilized to help the growth of algae and plankton.
