Abstract
Description
본 발명은 염화칼슘과 마그네슘을 함유한 액상의 제설제 조성물에 관한 것으로, 더욱 상세하게는 장기간 보관이 용이하고 친환경 중성물질로 유해가스 발생이 없을 뿐만 아니라 제설시간단축 및 제설작업이 용이하도록 하는 염화칼슘과 마그네슘을 함유한 액상의 제설제 조성물에 관한 것이다.The present invention relates to a liquid snow removing agent composition containing calcium chloride and magnesium, and more particularly, calcium chloride which is easy to store for a long time and does not generate harmful gases as an environmentally friendly neutral material, and shortens the snow removal time and snow removing operation. It relates to a liquid snow removing agent composition containing magnesium.
일반적으로 제설제는 눈의 어는점을 낮추어 내린 눈이 얼지않고 녹게 하는 것으로, 겨울철 도로에 쌓인 눈을 제설하기 위해 염화칼슘이나 소금(염화나트륨) 또는 모래와 적절하게 섞어서 도로에 흩뿌리고 있다.Generally, snow removing agent lowers the freezing point of the snow so that the frozen snow does not freeze and melts, and it is properly mixed with calcium chloride, salt (sodium chloride) or sand to remove snow accumulated on the road in winter and scattered on the road.
이처럼 눈이 많이 왔을 때 도로에 뿌리는 제설제는 주로 염화칼슘인데, 상기 염화칼슘은 석회암에 염산을 가하고 농축·가열하여 얻는 백색의 결정으로 콘크리트에 섞어서 동결 방지에 사용되며 특히 제설제로 사용되고 있다.The snow remover sprayed on the road when there is a lot of snow is mainly calcium chloride, which is a white crystal obtained by adding hydrochloric acid to limestone and concentrating and heating it.
이와 같이 결정(고체)상태의 염화칼슘은 어는점을 영하로 낮추어 얼음상태의 눈을 순식간에 녹게 만들기 때문에 제설 효과가 크긴 하나, 도로에 직접 살포할 경우 살포범위가 차량이 지나가는 범위에 한정되고, 제설제가 가로수까지 흩날려 광합성작용을 막아 가로수를 말라죽게 하며, 부식성이 강해 보도와 차도 사이 경계블록과 고가도로 방호벽을 마모시켜 환경과 도로 훼손 및 교통사고를 유발하는 문제점이 있었다.As such, the calcium chloride in the crystalline (solid) state lowers the freezing point to below zero to make ice snow melt in an instant, so the snow removal effect is great.However, when spraying directly on the road, the spraying range is limited to the range where the vehicle passes. It scattered to the trees and prevented photosynthesis, causing the trees to die, and the corrosiveness was so strong that there was a problem of causing damage to the environment, roads and traffic accidents by wearing the barrier blocks and the overpass barriers.
이처럼 결정(고체)상태의 제설제를 도로에 직접 살포할 경우 기후환경에 따라 제설제의 흩날림 현상이 발생하고, 고체상태로 살포되므로 반응속도가 늦으며, 녹는 과정에서 염소유해 가스발생으로 유아 및 노약자 호흡기질환에 매우 유해하고, 강 알카리성으로 부식성이 아주 강하여 살포차량 하부의 손실이 크며, 비산먼지 오염과 가스발생으로 대기오염을 유발하여 도로 하수구 등이 이물질과 함께 막힐 우려가 있어 배수에 문제가 우려되고 있다.When spraying snow crystals in the crystalline (solid) state directly on the road, scattering phenomenon of snow removers occurs depending on the climatic environment, and the spray rate is solid, so the reaction rate is slow. It is very harmful to the respiratory diseases of the elderly, strong alkaline and very corrosive, so there is a large loss of the lower part of the spraying vehicle, and air pollution is caused by scattering dust pollution and gas generation, which may cause road drains to be blocked with foreign substances. I'm concerned.
따라서 종래에는 상기와 같은 문제점을 해결하기 위해 고체상태의 제설제와 물을 교반하여 제설제 수용액을 살포하는 추세로 바뀌고 있는 실정이다.Therefore, conventionally, in order to solve the problems described above, the situation is changing to a trend of spraying a snow removal solution by stirring a snow removal agent in a solid state and water.
그러나, 상기한 제설제는 고체상태이므로 밀폐용기에 보관하고 습기오염이 없는 별도의 장소에 보관을 해야 하는 문제점이 있을 뿐만 아니라 특히 우리나라의 경우 사계절의 기후환경으로 인해 겨울철에 주로 제설제가 사용되는데, 상기 고체상태의 제설제는 보관상태에 따라 1년이 지나면 서로 용해되어 굳어버려서 사용 불 가능상태가 되므로 곧바로 폐기처분해야 하는 심각한 문제점이 있었다.However, since the above-mentioned snow removal agent is a solid state, it is not only a problem to store it in a closed container and to a separate place without moisture pollution, and in particular, in Korea, snow removal agent is mainly used in winter due to the climatic environment of the four seasons. The solid snow removal agent has a serious problem that must be disposed of immediately after being dissolved and hardened with each other after one year depending on the storage state, which becomes impossible to use.
더구나 상기 고체상태의 제설제를 살포하기 위해서는 교반장치의 교반수단인 프로펠러에 제설제가 직접 부딪히게 되어 장치의 훼손이 발생하고, 제설제의 균일한 살포가 곤란한 단점을 갖는 것이다. Moreover, in order to spray the solid snow removal agent, the snow removal agent directly hits the propeller which is the stirring means of the stirring device, causing damage to the device, and it is difficult to uniformly apply the snow removal agent.
또 최근에는 고체상태의 염화칼슘을 물과 함께 교반하여 수용액 상태로 만들어 살포하는 장치가 사용되기도 하나, 상기 장치는 고형의 염화칼슘을 지속적으로 공급하기 위한 제설제 공급장치와, 물과 염화칼슘을 교반하기 위한 교반장치와, 상기 교반이 완료된 수용액을 저장하는 수용액 저장탱크 등을 필요로 하므로 차량 적재함의 공간을 많이 차지하는 단점과 무거운 중량으로 인해 차량연료를 많이 소모하는 단점과, 이들 장치의 유지 및 보수가 힘든 단점을 갖는다.In recent years, a device for spraying solid calcium chloride with water to form an aqueous solution by spraying it is used. The device is a snow removing agent for continuously supplying solid calcium chloride and a device for stirring water and calcium chloride. It requires a stirring device, and an aqueous storage tank for storing the aqueous solution of the stirring is completed, the disadvantage of occupying a lot of space of the vehicle loading box and the disadvantage of consuming a lot of vehicle fuel due to heavy weight, and difficult to maintain and repair these devices Has disadvantages.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 본 발명은 염화칼슘과 마그네슘을 포함하는 액상의 제설제 조성물에 있어서, 상기 액상의 염화칼슘과 액상의 마그네슘이 8~9.5:0.5~2의 중량비로 배합되어 구성되는 염화칼슘과 마그네슘을 함유한 액상의 제설제 조성물을 제공하는 데 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, the present invention is a liquid snow removal composition comprising calcium chloride and magnesium, the liquid calcium chloride and liquid magnesium of 8 ~ 9.5: 0.5 ~ 2 An object of the present invention is to provide a liquid snow removing agent composition containing calcium chloride and magnesium, which is formulated in a weight ratio.
이처럼 본 발명은 액상의 상태로 유지되므로 장소구분 없이 장기간 보관이 용이하고 친환경 중성물질로 유해가스 발생이 없을 뿐만 아니라 눈을 액체화하는 속도가 매우 빨라 제설시간단축 및 제설작업이 용이하도록 하는 효과를 갖는다.As such, the present invention is easy to store for a long period of time without distinguishing the place, and there is no harmful gas generated as an environment-friendly neutral material, as well as the speed of liquid liquefying snow has the effect of shortening the snow removal time and easy snow removal. .
또 액상의 상태로 존재하기 때문에 초기작업(교반 및 혼합공정) 및 이로 인한 별도의 장치들이 필요 없을뿐더러 물에 바로 반응하므로 곧바로 제설제 수용액을 도로에 살포할 수 있는 것이다.In addition, since it exists in a liquid state, the initial work (stirring and mixing process) and the separate devices are not necessary, and because it reacts directly to water, it is possible to immediately spray the snow removal solution on the road.
또한 종래의 제설제 살포차량을 그대로 이용할 수 있을 뿐만 아니라 상기 살포차량의 단순화로 인해 차량유지 및 보수비용을 절감할 수 있고, 또 제설제를 액체상태로 도로에 살포하므로 그 살포반경이 매우 좋아 도로노면에 골고루 살포가능하며 세밀한 부분까지 살포되므로 제설작업이 용이하게 이루어지는 매우 유용한 발명인 것이다.In addition, it is possible to use the conventional snow removal spraying vehicle as it is, as well as to reduce the maintenance and repair cost of the vehicle by the simplification of the spreading vehicle, and also because the spraying snow is sprayed on the road in a liquid state, the spraying radius is very good It is a very useful invention that can be evenly sprayed on the road surface, and even to fine parts, making snow removal easy.
상기한 목적 및 효과를 달성하기 위한 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention for achieving the above objects and effects in more detail.
본 발명은 액상의 제설제 조성물에 있어서, 액상의 염화칼슘과 액상의 마그네슘을 8~9.5:0.5~2의 중량비로 배합되어 구성되어 진다.This invention is comprised by mix | blending liquid calcium chloride and liquid magnesium in the weight ratio of 8-9.5: 0.5-2 in the liquid snow removal agent composition.
상기 염화칼슘(CaCl2)은 염소(Cl)와 칼슘(Ca)이 반응하여 만들어진 이온성 화합물로, 액상(液狀)의 염화칼슘의 제조방법으로는 암모니아-소다법(솔베이법)을 이용한 공업적 제조방법이 있다. 이는 암모니아 증류탑의 폐액(廢液)을 농축하거나, 석회법으로 염소산나트륨을 제조함에 있어 부산물로 염화칼슘을 제조하는 등의 화학적 합성방법에 의한 제법이다.The calcium chloride (CaCl 2 ) is an ionic compound formed by the reaction of chlorine (Cl) and calcium (Ca), the industrial production method using the ammonia-soda method (Solbay method) as a method of producing a liquid calcium chloride There is this. This is a manufacturing method by a chemical synthesis method such as concentrating the waste liquid of the ammonia distillation column, or producing calcium chloride as a by-product in the production of sodium chlorate by the lime method.
또 액상의 마그네슘은 제조방법은 탄소에 의한 고온환원법이 있다. 이는 탄소에 의한 환원을 1900∼2400℃에서 행하고, 생성한 마그네슘 증기와 일산화탄소를 대량의 수소가스로 급랭(急冷)하여 생긴 마그네슘분말을 증류하고 융해하여 잉곳(ingot)으로 만든다. 또한 페로실리콘에 의한 환원법은 피전법이라 불리는데, 이 방법은 돌로마이트 MgCO3·CaCO3을 소성한 것에 75% 규소인 페로실리콘을 가해서 단광(團鑛)으로 만들고, 내열강으로 된 레토르트 속에 넣어 1200℃로 가열하여 환원시킨 다음, 이것을 0.001mmHg 정도인 진공에서 마그네슘을 증류하여 얻는다.In addition, liquid magnesium is produced by a high temperature reduction method using carbon. This is carried out at 1900-2400 ° C. for reduction by carbon, and the magnesium powder produced by quenching the produced magnesium vapor and carbon monoxide with a large amount of hydrogen gas is distilled and melted to form an ingot. In addition, the reduction method by ferrosilicon is called piezoelectric method, which is made by calcining dolomite MgCO 3 · CaCO 3 and adding 75% silicon to ferrosilic acid to make briquettes, and put it in a retort made of heat-resistant steel to 1200 ° C. After heating to reduce, this is obtained by distilling magnesium in a vacuum of about 0.001 mmHg.
본 발명에서는 액상의 제설제를 얻기 위해, 먼저 석회석을 염산에 녹여 액상의 염화칼슘을 얻고 상기 액상의 염화칼슘의 PH를 중성으로 조절하여 중성의 액상 염화칼슘을 얻는 단계와, 산화마그네슘(MgO)을 황산에 녹여 액상의 마그네슘을 얻고 상기 액상의 마그네슘의 PH를 중성으로 조절하여 중성의 액상 마그네슘을 얻는 단계와, 상기 중성의 액상 염화칼슘과 중성의 액상 마그네슘을 8~9.5:0.5~2의 중량비로 배합하는 단계에 의해 제조되어 진다.In the present invention, in order to obtain a liquid snow removing agent, first, limestone is dissolved in hydrochloric acid to obtain liquid calcium chloride, and the pH of the liquid calcium chloride is adjusted to neutral to obtain neutral liquid calcium chloride, and magnesium oxide (MgO) is added to sulfuric acid. Dissolving to obtain liquid magnesium and adjusting the pH of the liquid magnesium to neutral to obtain neutral liquid magnesium, and combining the neutral liquid calcium chloride and neutral liquid magnesium in a weight ratio of 8 to 9.5: 0.5 to 2 It is manufactured by.
상기한 방법에 의해 제조된 액상 염화칼슘은 맑고 투명하며, 유해가스 발생 이 없으며, 수소이온지수(PH)가 중성이어서 부식은 아주 미약하고, 친환경 중성물질일 뿐만 아니라 보관이 용이하고, 살포가 편리해 제설제로 매우 이상적인 상태가 된다.Liquid calcium chloride prepared by the above method is clear and transparent, no harmful gas is generated, and since the pH is neutral, corrosion is very weak, eco-friendly neutral material, easy to store, and easy to spray Zero is a very ideal state.
이처럼 액상 염화칼슘은 살포와 동시에 신속하게 습기와 반응하게 되어 반응 속도가 매우 느린 고체상태의 염화칼슘에 비해 매우 빨리 제설가능하게 되고, 제설작업이 용이하게 된다.As such, the liquid calcium chloride reacts rapidly with moisture at the same time as the spraying, so that the liquid calcium chloride can be removed very quickly compared to the solid calcium chloride, which is very slow in reaction rate, and easy to remove snow.
액상의 마그네슘(Mg)은 제설제로 살포시 살포차량 및 장치의 내부 부식을 방지하고, 상기 액상의 염화칼슘과 화합이 용이하게 이루어지며, 물과 급속하게 반응하게 되어 신속한 제설작업을 가능하게 하는 특징을 갖는다.Liquid magnesium (Mg) is characterized by preventing the internal corrosion of the spraying vehicle and the device when spraying with a snow removing agent, and easy compounding with the calcium chloride of the liquid, and reacts rapidly with water to enable rapid snow removal. .
이처럼 상기 액상의 염화칼슘과 액상의 마그네슘을 8~9.5:0.5~2 중량비로 배합하여 제설제로 사용할 경우 단순히 염화칼슘을 액체상태로 도로에 하는 것보다 제설장비의 보호 및 차량 무게의 감소, 제설시간을 단축할 수 있고 편리해지는 등의 장점을 갖게 된다.As such, when the liquid calcium chloride and the liquid magnesium are mixed at a weight ratio of 8 to 9.5: 0.5 to 2, and used as a snow removing agent, the protection of snow removing equipment and the weight of the vehicle are reduced and the snow removing time is shorter than simply using calcium chloride on the road as a liquid. It has advantages such as being able to and convenient.
이때 상기 중량비로 액상의 염화칼슘의 양에 비해 액상의 마그네슘 양이 2 이상인 경우에는 염화칼슘에 비해 마그네슘의 양이 너무 많아 제설이 용이하지 못하게 되며, 액상의 마그네슘이 0.5 이하의 경우에는 마그네슘의 양이 너무 적어 제설제 살포차량의 각 장치에서 부식이 발생하게 되는 단점을 갖는다.In this case, when the amount of liquid magnesium is 2 or more compared to the amount of liquid calcium chloride in the weight ratio, the amount of magnesium is too high compared to the amount of calcium chloride, so that snow removal is not easy, and when the amount of liquid magnesium is 0.5 or less, the amount of magnesium is too high. At least, there is a disadvantage in that corrosion occurs in each device of the snow removal vehicle.
이처럼 상기와 같이 본 발명을 비록 한정된 실시예에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.As described above, the present invention has been described by means of a limited embodiment, but the present invention is not limited thereto and will be described below by the person skilled in the art and the technical spirit of the present invention. Various modifications and variations are possible within the scope of the claims.
