Abstract
Description
본 발명은 저염화물계 액상제설제 제조방법에 관한 것으로, 보다 상세하게는 금속 또는 비철금속에 대한 부식과 이온화 현상을 방지시켜 저부식성 특성을 갖도록 개선된 저염화물계 액상제설제 제조방법에 관한 것이다.The present invention relates to a method for preparing a low chloride liquid snow preparation agent, and more particularly, to a method for preparing a low chloride liquid snow preparation agent which has been improved to have low corrosion resistance by preventing corrosion and ionization of metals or nonferrous metals.
일반적으로, 제설용 제품들은 식염(염화나트륨), 염화칼슘 및 염화마그네슘 등의 염화물계와 칼슘 마그네슘 아세테이트(CMA), CMO(Calcium Magnesium of Organic acids) 및 요소가 있는데 이 중에서 가격이 저렴하다는 이유로 염화물계 제설제를 가장 많이 사용하고 있다.In general, snow removal products include chloride-based salts such as sodium chloride, calcium chloride and magnesium chloride, calcium magnesium acetate (CMA), Calcium Magnesium of Organic acids (CMO), and urea. I use the most.
염화물계 제설제품류는 강한 독성이나 부식성 등으로 자동차, 시설구조물 및 생태계에 막대한 악영향을 초래하고 있으나 이를 대체할 제품은 미비한 실정이다.Chloride-based snow removal products have a strong adverse effect on automobiles, facility structures, and ecosystems due to strong toxicity and corrosiveness, but there are few products to replace them.
또한, 염화칼슘, 식염이 갖는 강한 부식성 때문에 도로(콘크리트, 아스팔트), 교량, 차량, 시설구조물 등의 내구성 저하 그리고 지하수, 하천 및 토양오염 등으로 생태계에 막대한 영향을 초래하고 있어 선진국에서는 환경을 보호하고 신속한 제설작업이 가능한 친환경 개발에 심혈을 기울이고 있는 실정이다.In addition, due to the strong corrosiveness of calcium chloride and salt, the degradation of durability of roads (concrete, asphalt), bridges, vehicles, and structures, etc., as well as groundwater, rivers, and soil pollution, have an enormous impact on the ecosystem. Efforts are being made to develop eco-friendly products that enable rapid snow removal.
이와 관련하여, 주요 선진국들의 예를 살펴보면, 미국의 경우 영상에서 영하 5℃까지의 기온에서는 암염(NaCl)과 부순 모래를 섞어서 사용하며, 영하 5℃ 미만일 경우에는 암염의 양을 줄이거나 염화칼슘을 부순 모래와 섞어서 사용하고 있다.In this regard, in the case of major industrialized countries, in the United States, the mixture of rock salt (NaCl) and crushed sand is used at temperatures up to minus 5 ° C. It is mixed with sand.
캐나다의 경우에는 주로 소금을 사용하고 있으며 노면 동결 등 필요시 모래를 사용한다.In Canada, salt is mainly used, and sand is used when necessary, such as freezing the road.
스위스의 경우에는 소금과 소금용액을 혼합하여 주로 살포하고 있으며 산악 및 도시 보도는 모래를 살포하고 있으며, 요구 서비스 수준이 높은 도로에는 사전에 동결방지제를 살포하고 있고, 특히 교량에는 자동 제빙제 살포 시스템을 시범 설치하여 운영하고 있다.In Switzerland, salt and salt solutions are mixed and sprayed, mountain and urban sidewalks are sanded, and antifreeze is applied in advance on roads with high service requirements, especially on bridges. Has been installed and operated.
일본의 경우에는 동절기 다설/한랭 지역의 도로교통을 확보하기 위한 특별법을 마련하여 대상 노선을 지정 시행하고 있다. 특히, 슬러쉬 제거장비, 풍력 등을 이용한 융설시설, 폐열을 이용한 고온수 살포융설 시설의 신기술을 개발하였다.In Japan, a special law has been established to secure road traffic in the winter snow and cold regions. In particular, the company developed new technologies for slush removal equipment, snow melting facilities using wind power, and hot water spraying snow melting facilities using waste heat.
국내에서는 일반적으로 제설에는 염화칼슘, 염화나트륨 등 염화물계 고체 제설제를 사용하고 있는데, 염화물계 특유의 강한 독성으로 인해 시설물, 구조물은 물론 차량 등에 직접 부식작용을 일으키고 용해액으로 인해 강과 하천 토지의 오염 등 환경 파괴가 심각한 실정이다.In Korea, chloride-based solid snow removers such as calcium chloride and sodium chloride are generally used for snowmaking. Due to the strong toxicity of chloride-based, it causes direct corrosion on facilities, structures, vehicles, etc. Environmental destruction is a serious situation.
또한, 이같은 고체 제설제 사용의 단점과 제설제의 과다 사용 및 모래를 동시에 살포함으로 인해 사후 청소작업이 필요하여 고비용을 지출하는 문제가 있다.In addition, the disadvantages of using such a solid snow remover and the excessive use of the snow remover and spraying sand at the same time requires a post-cleaning operation, there is a problem of spending a high cost.
구체적으로, 염화칼슘이나 염화나트륨은 염소이온이 존재하므로 철(Fe)과 반 응하면 급격히 염화철(FeCl2)를 형성해 자동차, 철근, 철골 구조물을 심각하게 부식시킨다.Specifically, since calcium chloride or sodium chloride has chlorine ions, when reacted with iron (Fe), iron chloride (FeCl 2 ) is rapidly formed to severely corrode automobiles, steel bars and steel structures.
또한, 앞서 설명하였듯이 용해된 염화칼슘이 토양 및 하천으로 유입됨으로써 발생되는 피해는 도로, 토양 산성화에 의한 환경(도로주위의 생물, 상수원, 수질, 가로수 등) 오염의 주범으로 그 피해의 정도는 액수로 계산할 수조차 없는 실정이다.In addition, as described above, the damage caused by the inflow of dissolved calcium chloride into the soil and rivers is the main cause of pollution of the environment (biotics, water sources, water quality, roadsides, etc.) caused by road and soil acidification. It can not be calculated.
이에, 비염화물계 제설제에 대한 연구 개발이 다수 진행되고 있으나 비용이 비싸다는 한계와, 염화물계와 비교하였을 때 제설효과의 신속성에 있어 다소 뒤지는 단점을 갖고 있다.As a result, many researches and developments for non-chloride snow removal agents have been conducted, but they have a disadvantage in that the cost is high and the speed of snow removal effect is somewhat lower than that of the chloride system.
반면, 기존의 염화물계 제설제에서 염화물의 함량을 낮춰 피해를 줄이려는 노력들이 있었으며, 이를 저염화물계 제설제라 통칭하고 있다.On the other hand, efforts have been made to reduce the damage by reducing the chloride content in the conventional chloride snow removing agent, which is collectively referred to as low chloride snow removing agent.
이러한 저염화물계 제설제는 저가형 제설제로서 염화물의 함량을 낮춘 것이 특징이라 할 수 있다.The low chloride snow removal agent is a low-cost snow removal agent may be characterized by lowering the chloride content.
그럼에도 불구하고, 개시되고 있는 종래 저염화물계 제설제의 조성중 염화마그네슘 등은 제설 작업시 제설 장비의 살포용 슈트에 흡착되어 아칭(Arching) 현상, 즉 슈트(호퍼) 내에 Mg이 붙어서 떨어지지 않는 현상을 초래하고, 이로 인해 제설제 살포가 곤란하게 되어 작업 효율을 저하시키며, 혼합형 제설제의 경우에는 녹는점이 불균일하다는 단점이 있고, 부식방지제도 입자가 미세하여 바람에 날리거나 살포기의 바닥에 가라앉아서 부식 방지 효과가 매우 미약하다는 단점이 있었다.Nevertheless, magnesium chloride and the like in the composition of the conventional low chloride snow removing agent are adsorbed to the spraying chute of the snow removing equipment during the snow removing operation to prevent arching, that is, the phenomenon that Mg is stuck in the chute (hopper) and does not fall. This results in difficulty in spraying snowplow, reducing work efficiency. In the case of mixed snowplows, the melting point is uneven.The corrosion inhibitor also has fine particles, which are blown by the wind or settled on the bottom of the spreader for corrosion. The disadvantage is that the prevention effect is very weak.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, 염소이온이 환경부의 친환경 제설제 인증기준(EL 610)인 20.0% 미만이며 기타 성능과 품질 및 환경 관련 기준에 부합되고, 특히 염소 이온으로 인한 부식 방지와, 마그네슘이 금속이나 살포장비의 슈트 또는 노즐에 아칭 현상을 발생시키는 것을 방지하여 제설 작업의 효율성을 증가시킬 수 있도록 한 저가형의 저염화물계 액상제설제를 제공함에 그 주된 해결 과제가 있다.The present invention was created in view of the above-described problems in the prior art, chlorine ion is less than 20.0% of the environmentally friendly snow removing agent certification criteria (EL 610) of the Ministry of Environment and other performance, quality and environmental standards Low-cost, low-chloride, low-chloride liquid snow remover, which can increase the efficiency of snow removal by preventing corrosion from chlorine ions and preventing magnesium from arching into chutes or nozzles of metals and spreading equipment.

이하에서는, 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail.
본 발명은 염소이온이 20% 이하로 포함된 저염화물계 저부식성, 저독성 액상 제설제로서 인체에 무해하고 친환경적이며, 특히 마그네슘이 금속이나 살포장비의 슈트 또는 노즐에 아칭 현상을 발생시키는 것을 방지하여 제설 작업의 효율성을 증가시킬 수 있고, 노면 청소차량의 작업용수로 활용할 수 있어 미세먼지 제거와 고가의 장비를 효율적으로 운영할 수 있도록 하여 준다.The present invention is a low chloride low corrosion and low toxicity liquid snow removing agent containing less than 20% of chlorine ions, which is harmless to the human body and environmentally friendly, and in particular, prevents magnesium from arching the chute or nozzle of a metal or spraying equipment. It can increase the efficiency of snow removal work and can be used as the work water of road cleaning vehicles, so it can remove fine dust and operate expensive equipment efficiently.
뿐만 아니라, 본 발명에 따른 액상 제설제는 염소이온이 환경부의 친환경 제설제 인증기준(EL 610)인 20.0% 보다 낮은 13~19% 여서 부식 방지 효과가 뛰어나고, 또한 저렴한 비용으로 영하 20℃에서 영하 60℃까지 사용할 수 있는 액상 제설제를 쉽게 제조할 수 있어 제설제 구입에 따른 비용도 절감할 수 있도록 하여 준다.In addition, the liquid snow removing agent according to the present invention is chlorine ion is 13 ~ 19% lower than 20.0% of the environment-friendly snow removing agent certification criteria (EL 610) of the Ministry of Environment, excellent corrosion protection, and also at a low cost below zero at 20 ℃ The liquid snow removing agent that can be used up to 60 ℃ can be easily manufactured, thus reducing the cost of purchasing the snow removing agent.
이를 위해, 본 발명에 따른 제설제는 염소이온이 13~19% 함유된 저부식성 액상 제설제로서, 중량%로 염화마그네슘:38.0-45.0중량%, 초산나트륨:3.0-6.0중량%,글리세린:2.0-5.0중량%, 구연산나트륨:1.0-3.0중량% 잔부 물로 조성되어 염화마그네슘의 금속 또는 비철금속에 대한 부식과 이온화 현상을 방지시킨 것으로, 특히 Mg이 Fe에 달라붙는 현상을 방지하도록 구성된 것에 특징이 있다.To this end, the snow removing agent according to the present invention is a low-corrosive liquid snow removing agent containing 13-19% of chlorine ions, in weight% magnesium chloride: 38.0-45.0% by weight, sodium acetate: 3.0-6.0% by weight, glycerin: 2.0 -5.0% by weight, sodium citrate: 1.0-3.0% by weight of the residue to prevent the corrosion and ionization of magnesium chloride metals or non-ferrous metals, characterized in that it is configured to prevent the sticking of Mg to Fe .
그러면, 상기의 성분과 조성비를 갖는 본 발명 액상 제설제 조성물의 수치한정 사유에 대하여 설명한다.Then, the reason for numerical limitation of the liquid snow removal agent composition of this invention which has said component and composition ratio is demonstrated.
[염화마그네슘:38.0-45.0중량%][Magnesium chloride: 38.0-45.0 wt%]
염화마그네슘은 종래 제설제의 주원료로 사용되던 염화칼슘이 지니고 있는 고부식성을 개선하기 위해 대체 첨가되는 것으로, 염화칼슘보다 낮은 융해열을 제공하기는 하지만 금속에 대한 부식성이 적고, 친환경적이며, 어는점을 내리고 재결빙을 지연시키는 작용 측면에서 사용된다.Magnesium chloride is added as an alternative to improve the high corrosion resistance of calcium chloride, which has been used as a main raw material of conventional snow remover.It provides lower heat of fusion than calcium chloride, but it is less corrosive to metal, environmentally friendly, freezes and freezes. It is used in terms of the action of delaying.
물론, 염화마그네슘 자체만으로는 제설제로서 완전한 효과를 제공할 수 없기 때문에 후술되는 다른 성분, 특히 초산나트륨 및 구연산나트륨과의 적정 조성비가 매우 중요하다.Of course, since magnesium chloride alone cannot provide a complete effect as a snow removal agent, an appropriate composition ratio with other components described below, in particular sodium acetate and sodium citrate, is very important.
특히, 본 발명에서는 무수물 형태의 상기 염화마그네슘은 물론 상온에서 용액형태로 존재하는 6수화물도 사용될 수 있다.In particular, the magnesium chloride in the anhydride form as well as the hexahydrate present in solution form at room temperature may be used in the present invention.
뿐만 아니라, 필요에 따라서는 염화마그네슘의 일부가 염화나트륨으로 대체될 수도 있는데, 이는 염화마그네슘이 고가이므로 이와 같이 염화마그네슘의 일부가 염화나트륨으로 대체되면 코스트를 낮출 수 있고, 또 염화나트륨은 용해속도가 다소 느려 살포 후에도 소정기간 동안 알갱이 상태로 존재하는데, 이와 같은 이유로 염화나트륨을 혼합하면 염화나트륨이 녹기 전까지의 소정시간 동안에는 염화나트륨에 의해 미끄러짐 방지 효과를 기대할 수도 있다.In addition, if necessary, some of the magnesium chloride may be replaced with sodium chloride. Since magnesium chloride is expensive, the replacement of some of the magnesium chloride with sodium chloride may lower the cost, and sodium chloride may have a slightly slower dissolution rate. After spraying, the particles are present in the granular state for a predetermined time. For this reason, when sodium chloride is mixed, anti-slip effect may be expected by sodium chloride for a predetermined time until sodium chloride is dissolved.
여기에서, 상기 염화마그네슘을 38중량% 미만으로 첨가하게 되면 융해열이 떨어지고 반응성이 약해 지속성을 유지할 수 없으므로 재결빙을 초래하고, 45중량% 를 초과하게 되면 금속에 대한 부식성이 증가하게 되므로 상기 범위로 한정하여야 한다.In this case, when the magnesium chloride is added in less than 38% by weight, the heat of fusion falls and the reactivity is weak so that it cannot maintain its persistence, resulting in re-freezing. It should be limited.
[초산나트륨:3.0-6.0중량%][Sodium acetate: 3.0-6.0 wt%]
초산나트륨(sodium acetate)은 아세트산과 나트륨이 만드는 염으로, 약한 산과 강한 염기가 만든 염이며, 그 수용액은 약한 알칼리성을 보이고, 융해열이 크므로 보통 난방기구의 보온재료 등에 사용된다.Sodium acetate is a salt made by acetic acid and sodium. It is a salt made of weak acid and strong base. The aqueous solution shows weak alkalinity and heat of fusion, so it is usually used for heating materials of heating appliances.
본 발명에서는 큰 융해열을 이용하여 빙점 강하와 재결빙 시간을 지연시키기 위해 사용된다.In the present invention, a large heat of fusion is used to delay the freezing point drop and the refreezing time.
특히, 초산나트륨의 입자사이즈를 0.3㎜ 이상으로 하는 경우 붕해성이 우수한 것으로 알려져 있으며, 이에 더하여 상온에서 1000cps 이하의 점도를 갖는 액상을 사용할 경우 붕해성은 더욱 향상되는 것으로 알려져 있으므로 본 발명에서도 이 조건에 맞춘다면 더욱 더 우수한 액상 제설제를 제조할 수 있을 것이다.Particularly, when the particle size of sodium acetate is 0.3 mm or more, the disintegration property is known to be excellent. In addition, the disintegration property is known to be further improved when using a liquid having a viscosity of 1000 cps or less at room temperature. According to the present invention it will be possible to produce even better liquid snow removing agent.
여기에서, 상기 초산나트륨을 3.0중량% 미만으로 첨가하게 되면 붕해성이 급격히 떨어지고, 6.0중량%를 초과하여 첨가하게 되면 안정성이 떨어짐은 물론 다른 성분들과의 상관관계를 고려하여 상기 범위로 한정하여야 한다.Herein, when the sodium acetate is added in less than 3.0% by weight, disintegration is drastically reduced, and when it is added in excess of 6.0% by weight, the stability is deteriorated as well as the correlation with other components should be limited to the above range. do.
[글리세린(Glycerin):2.0-5.0중량%][Glycerin: 2.0-5.0 wt%]
글리세린은 저온에서 탁월한 안정성과 재결빙 지연효과를 갖도록 하기 위해 첨가되는 물질로, 희박용액의 자극을 완화하는 특성을 갖는다.Glycerin is a substance added to have excellent stability at low temperatures and delayed re-freezing, and has a property of alleviating the stimulation of the lean solution.
특히, 상기 글리세린은 어는점 내림에 도움을 주며 저온에서도 제품의 안정성을 향상시킨다.In particular, the glycerin helps to freeze and improve the stability of the product even at low temperatures.
이러한 글리세린을 2중량% 미만으로 첨가하게 되면 안정성과 재결빙 지연효과가 급격히 저하되고, 5중량%를 초과하여 첨가하게 되면 어는점 강하 및 융빙을 방해할 수 있으므로 다른 성분들의 첨가량을 고려하여 상기 범위로 첨가되어야 한다.When the glycerin is added in an amount less than 2% by weight, the stability and re-freezing delay effect are drastically lowered, and when it is added in excess of 5% by weight, the freezing point drop and melting may be hindered. Must be added.
[구연산나트륨:1.0-3.0중량%][Sodium Citrate: 1.0-3.0 wt%]
구연산나트륨은 자연에 존재하는 동식물의 대사 물질로서 감귤류에서 가장 많이 얻을 수 있는 유기산으로서, 상쾌한 신맛을 내는 산미제, PH 조절제, 산화방지제, 세제, 수렴제 등으로 식품, 의약산업에 널리 사용되고 있다.Sodium citrate is a metabolite of plants and animals that exist in nature and is the most organic acid obtained from citrus fruits. It is widely used in the food and pharmaceutical industries as an acidic agent, a pH regulator, an antioxidant, a detergent, astringent, etc., which has a refreshing sour taste.
이러한 구연산나트륨은 물 분자 함유에 따라 함유구연산, 무수구연산으로 구분되며, 구연산나트륨, 구연산칼슘, 구연산칼륨 등의 염과 구연산 트리에테르, 구연산 아세틸, 구연산 에스테르 등의 형태로도 이용된다.Such sodium citrate is divided into citric acid and citric anhydride according to the water molecule content, and is also used in the form of salts such as sodium citrate, calcium citrate and potassium citrate, and citric acid triether, acetyl citrate and citric acid ester.
특히, 구연산나트륨은 금속표면의 산화물을 제거하여 금속의 부식을 방지하는 능력과 금속표면의 변색을 방지하는 능력이 있는 바, 본 발명에서는 이러한 성질을 이용한다.In particular, sodium citrate has the ability to remove oxides on the metal surface to prevent corrosion of the metal and to prevent discoloration of the metal surface, and the present invention utilizes this property.
또한, 구연산나트륨은 수소이온 농도조절, 악취방지, 완충제, 활성성분의 안전성 유지, 보존성 상승, 산화방지제 등으로 많이 사용되고 있다. 이와 같이, 구연산나트륨은 식품과 의약품에 사용되는 식용에 안전한 친환경성 천연물질이다.In addition, sodium citrate is widely used as hydrogen ion concentration control, odor prevention, buffer, maintaining the safety of the active ingredient, increasing the shelf life, antioxidants and the like. As such, sodium citrate is an edible, environmentally friendly natural material used in food and medicine.
본 발명에 따른 구연산나트륨은 마그네슘의 이온화 현상을 억제시켜 아칭 현상을 방지하고 부식을 억제하기 위해 사용되는 것으로, 1.0중량% 미만으로 첨가되게 되면 마그네슘의 이온화 현상 억제력이 떨어져 아칭 현상을 방지할 수 없고, 3.0중량%를 초과하게 되면 반응성이 일정하게 되므로 다른 성분들과의 상관관계를 고려하여 상기 범위로 한정되어야 한다.Sodium citrate according to the present invention is used to inhibit the ionization phenomenon of magnesium to prevent the arching phenomenon and to suppress corrosion, when added to less than 1.0% by weight can not prevent the arching phenomenon due to the lowering of the ionization phenomenon of magnesium When it exceeds 3.0% by weight, the reactivity becomes constant and should be limited to the above range in consideration of correlation with other components.
이와 같은 조성에 잔부로 물이 첨가됨으로써 본 발명에 따른 저염화물계 액상 제설제 조성물이 완성되게 되는데, 이를 통해 저염화물계 제설제에서 가장 중요하게 요구되는 특성인 신속한 제설과, 재결빙의 지연, 저부식성을 통한 환경에 대한 피해 최소화를 달성할 수 있게 된다.By adding water to the remainder in such a composition, the low chloride liquid snow removal composition according to the present invention is completed, and through this, rapid snow removal and delay of refreezing, which are the most important characteristics of the low chloride snow removal agent, are achieved. Corrosion can be achieved to minimize damage to the environment.
특히, 본 발명에 따른 저염화물계 액상 제설제는 제설 작업시 제설 장비의 살포용 슈트에 흡착되어 Mg이 잘 떨어지지 않아 제설제 살포를 곤란하게 하는 아칭(Arching) 현상을 방지하도록 마그네슘의 이온화를 억제함으로써 제설제 살포를 용이하게 한 장점을 가진다.In particular, the low chloride liquid snow removal agent according to the present invention is adsorbed by the spray chute of the snow removal equipment during the snow removal operation Mg is not falling well to suppress the ionization of magnesium to prevent the arching phenomenon that makes it difficult to spray snow removal agent This has the advantage of easy snow spraying.
한편, 상술한 조성으로 이루어진 본 발명에 따른 제설제 조성물은 다음과 같은 과정을 거쳐 친환경 저염화물계 액상 제설제로 제조될 수 있다.On the other hand, the snow removal composition according to the present invention made of the above-described composition can be prepared as an environmentally friendly low chloride liquid snow removal agent through the following process.
먼저, 본 발명 조성비에 따른 물을 1차 교반기에 넣고, 염화마그네슘을 38-45중량% 첨가한 상태에서 10분간 교반하는 1차 교반과정을 거치게 된다.First, the water according to the composition ratio of the present invention is put in a primary stirrer, and undergoes a first stirring process of stirring for 10 minutes in the state of adding 38-45% by weight of magnesium chloride.
이렇게 물과 염화마그네슘을 먼저 교반하는 이유는 염화마그네슘이 충분히 희석되도록 하여 후속 첨가되는 성분들과의 반응성을 높이도록 하기 위함이다.The reason for stirring the water and magnesium chloride first is to allow the magnesium chloride to be sufficiently diluted to increase the reactivity with the components added subsequently.
이어, 교반 완료된 물과 염화마그네슘의 혼합물을 여과기에 여과시켜 여과액만을 따로 모은 다음 2차 교반기에 넣고, 초산나트륨:3.0-6.0중량%,글리세린:2.0-5.0중량%, 구연산나트륨:1.0-3.0중량%을 순차로 투입한 다음 5분간 교반하는 2차 교반과정을 거침으로써 본 발명에 따른 액상 제설제를 제조할 수 있게 된다.Then, the mixture of stirred water and magnesium chloride was filtered through a filter, and only the filtrate was collected separately and placed in a secondary stirrer, and sodium acetate: 3.0-6.0 wt%, glycerin: 2.0-5.0 wt%, sodium citrate: 1.0-3.0 After the addition of the weight% in order and then a second stirring process of stirring for 5 minutes it is possible to manufacture a liquid snow removing agent according to the present invention.
이때, 상기 2차 교반기에서의 교반속도는 250~300 rpm으로 교반하는 것이 바람직한데 이는 저속 교반을 통해 성분조성들의 충분하고 안정적인 혼합이 이루어지도록 하기 위함이다.At this time, the stirring speed in the secondary stirrer is preferably stirred at 250 ~ 300 rpm to achieve a sufficient and stable mixing of the composition of the composition through the low-speed stirring.
여기에서, 상기 2차 교반과정 중 초산나트륨, 글리세린, 구연산나트륨을 정해진 조성비로 한꺼번에 순차 투입한 후 교반할 수도 있지만, 더욱 더 안정적인 반응과 충분한 혼합을 위해 순차 투입시마다 5분씩 교반하는 형태로 제조할 수도 있다.Here, the sodium acetate, glycerin, sodium citrate during the second agitation process may be added after stirring at a time in a predetermined composition ratio, but may be prepared in the form of stirring for 5 minutes each time in order for a more stable reaction and sufficient mixing. It may be.
또한, 상술한 제조과정의 작업환경은 성분들의 특성과 반응성을 고려하여 상온~25℃에서 이루어져야 하며, 이렇게 조성된 조성물은 어는점이 -20~-60℃로서, 제설 작업중 재결빙의 문제가 없어져 제설작업의 용이성이 확보된다.In addition, the working environment of the above-described manufacturing process should be made at room temperature ~ 25 ℃ in consideration of the characteristics and reactivity of the components, the composition thus formed is a freezing point of -20 ~ -60 ℃, eliminating the problem of re-freezing during snow removal work Ease of use is ensured.
따라서, 본 발명품은 용도가 다양하고 가격이 저렴하므로 보급이 용이한 친환경 제설제를 제공하게 될 것이다.Therefore, the present invention will provide an eco-friendly snow removing agent that is easy to spread because of its various uses and low price.
이하, 실시예에 대하여 설명한다.Hereinafter, an Example is described.

그리고, 상술한 바와 같은 본 발명에 따른 액상 제설제를 이용하여 제설 작업을 실시할 때 살수장비에 마그네슘이 고착되지 않기 때문에 살수효율도 향상되며, 또한 노면 청소차량용 작업용수로도 활용가능하게 되어 동절기 도로 청소와 미세먼지 제거에도 탁월한 효과를 제공할 것으로 기대된다.In addition, when the snow removal operation using the liquid snow removal agent according to the present invention as described above, because the magnesium is not fixed to the watering equipment, the watering efficiency is also improved, and also it can be used as work water for road cleaning vehicles and winter roads.
