Description
본 발명은 제설제 조성물 및 그 제조방법에 관한 것이다. The present invention relates to a snow removing composition and a method for producing the same.
현재 사용되고 있는 제설제로는 소금(NaCl)과 염화칼슘(CaCl2) 등이 있으며, 주로 겨울철 한랭지에 적설시 고속도로 교통을 원활히 하기 위해 사용하고 있다. 제설제를 고속도로나 교량 등지에 살포하는 목적은, 노상의 설빙을 융해시키고, 노상 수분의 재결빙을 방지하며, 압설을 노면으로부터 탈리시켜 제설작업이 용이하게 하는데 있다. 제설제는 또한 모래 등과 혼합 살포하여 미끄럼 마찰저항 계수를 향상시키기도 한다. Currently used snow removers include salt (NaCl) and calcium chloride (CaCl 2 ), and they are mainly used for smooth highway traffic during snowfall in winter cold areas. The purpose of spraying snow removal agents on highways, bridges, etc. is to melt snow on the road, prevent refreezing of water on the road, and to make snow removal easy by removing snow from the road surface. The snow remover also mixes with sand or the like to improve the sliding friction coefficient.
제설제의 선택조건으로는, 1) 가격이 싸고 구입이 쉬우며 보존이 용이할 것, 2) 살포후 확실한 효과를 나타내야 하며 장기간 지속효과가 있을 것, 3) 미끄럼 마찰을 증대시킬 것, 4) 포장도로 및 동식물에 대한 부작용이 적을것, 5) 살포작업이 용이하고 노면에 균등하게 살포될 수 있을 것 등을 들 수 있으며, 소금과 염화칼슘은 이러한 조건에 잘 부합된다고 할 수 있다. The choice of snow remover is 1) cheap price, easy to purchase, easy to preserve, 2) have a definite effect after spraying, long lasting effect, 3) increase sliding friction, 4) There are few side effects on pavement and flora and fauna, 5) It is easy to apply spraying and can be evenly sprayed on the road. Salt and calcium chloride can meet these conditions well.
그러나, 소금과 염화칼슘이 포함하고 있는 염화 이온의 독성으로 말미암아 각종 시멘트, 콘크리트 건축물과 도로, 교량, 자동차, 지하 전선 케이블, 상하수도관 등에 부식현상을 유발하는 등 심각한 피해를 입히고 있다. 또한, 이러한 염들이 물에 녹아 강이나 호소(湖沼)로 흘러들어감으로써 수중 생태계의 파괴, 음용수의 오염 및 도로 주변의 식물들에 피해를 입히는 등 여러 가지 환경 문제를 야기시키고 있는 실정이다. 또, 염화칼슘은 제설 후에 제습하는 과정에서 지속력이 떨어져 쉽게 재결빙되는 문제가 있었다. However, the toxicity of chloride and chlorine ions, which are contained in salt and calcium chloride, causes serious damage such as corrosion of various cements, concrete buildings, roads, bridges, automobiles, underground cables, water pipes and sewers. In addition, these salts are dissolved in water and flow into rivers or lakes, causing various environmental problems such as destruction of aquatic ecosystems, pollution of drinking water, and damage to plants around roads. In addition, calcium chloride has a problem in that it is easily re-frozen due to low sustainability in the process of dehumidification after snow removal.
우리나라의 경우 이러한 제반 문제에도 불구하고 염화칼슘을 주된 제설제로 사용하고 있으며 고속도로나 교량에 살포하는 양이 대략 1년에 10,000톤 정도가 된다. 하지만 세계적으로 보면 기존 제설제 중 특히 소금이 제빙효과가 우수하고 가격이 저렴하기 때문에 가장 널리 사용되고 있다. In Korea, despite these problems, calcium chloride is used as a major snow removal agent, and the amount of spraying on highways and bridges is about 10,000 tons per year. However, in the world, salt is most widely used because of its excellent ice making effect and low price.
기존 제설제에 대한 환경오염과 부식피해가 점차 심각해지자, 1970년대 말 미국에서는 대체용 제설제를 찾기 위한 연구를 시작하였으며, 제설제로서의 물리·화학적 특성, 환경에 미치는 영향, 독성 여부, 생산비 등을 고려하여 CMA(Calcium Magnesium Acetate)를 대체용 제설제로서 선정하였다. CMA는 빙점강하에 의한 제빙효과가 소금과 유사하며, 부식성이 대단히 작고, 물속에 용해된 후 Ca 이온과 Mg 이온은 토양생물의 영양분이 되고, 초산 이온은 박테리아에 의해 생분해되어 환경오염의 위험성이 거의 없다. 그러나 이와 같은 장점에도 불구하고 대량생산은 아직 이루어지지 않고 있는데, 그 주요인은 바로 높은 생산원가이다. As environmental pollution and corrosion damage to existing snow removal agents became more severe, research in the United States began to search for alternative snow removal agents in the late 1970s.The physical and chemical properties of snow removal agents, their environmental impact, toxicity, production costs, etc. In consideration of this, CMA (Calcium Magnesium Acetate) was selected as an alternative snow remover. CMA has a deicing effect similar to that of salt, and it is very corrosive. After dissolving in water, C ions and Mg ions become nutrients to soil organisms, and acetic acid ions are biodegraded by bacteria. Few. However, despite these advantages, mass production has not yet taken place, and the main reason is high production costs.
순수한 CMA의 가격은 현재 톤당 600불로 소금값의 27배에 달하며, 이 가격의 80% 이상이 초산, 칼슘, 마그네슘 등의 원료값에 기인한다. 종래의 유기산은 석유나 천연가스로부터 합성되었기 때문에 생산가가 높을 수밖에 없었고, 이에 생산가를 줄이기 위한 여러 가지 연구가 진행되어 왔다. 순수한 당이나 전분을 이용한 세포 고정식 초산 박테리아 발효 공정을 사용하여 CA(Calcium Acetate) 생산비를 톤당 258불까지 낮출 수 있었으나, 초산 박테리아의 까다롭고 복잡한 발효조건과 공정으로 인해, 비교적 다루기 쉬운 프로피온산 박테리아를 이용하여 초산과 프로피온산의 비율이 약 2:1인 CMO(Calcium Magnesium salt of Organic acids) 생산방법이 제안되어 있다.Pure CMA is currently priced at $ 600 per tonne, 27 times the price of salt, and more than 80% of this price comes from raw materials such as acetate, calcium and magnesium. Since the conventional organic acid is synthesized from petroleum or natural gas, the production cost is high, and various studies have been conducted to reduce the production cost. Using a cell-fixed acetic acid bacteria fermentation process using pure sugar or starch, the production cost of Calcium Acetate (CA) could be lowered to $ 258 / ton, but due to the complicated and complicated fermentation conditions and processes of acetic acid bacteria, it was possible to use relatively easy propionic acid bacteria. Therefore, a method of producing CMO (Calcium Magnesium salt of Organic acids) in which the ratio of acetic acid and propionic acid is about 2: 1 has been proposed.
이상 설명한 제설제와 기타 다른 제설제의 예를 간단히 하기 표 1에 나타낸다. Examples of the snow removal agent described above and other snow removal agents are briefly shown in Table 1 below.
한편, 제설제의 선정/살포 기준은 동결온도가 낮고 융해성, 속효성이 우수하며 효과가 지속적이어야 하고, 가격이 저렴하며 공급이 원활해야 할 뿐 아니라, 보관, 운반 및 살포가 용이해야 하고, 동식물에 대한 피해, 철 구조물 및 포장도로의 부식 등의 부작용이 적어야 한다. On the other hand, the selection / spreading criteria of the snow remover should be low in freezing temperature, excellent in meltability, fast-acting effect, continuous effect, inexpensive and smooth supply, easy to store, transport and spray, and There should be less side effects, such as damage to steel, corrosion of steel structures and pavements.
