Description
본 발명은 석면 처리제 및 이를 이용한 석면 처리방법에 관한 것이다.The present invention relates to an asbestos treatment agent and an asbestos treatment method using the same.
석면(asbestos)은 길이가 5 ㎛ 이상이며, 길이 대 폭의 비가 3:1 이상인 가늘고 긴 형태로 산출된 함수 규산염 광물을 총칭하는 것으로, 불연성, 단열성, 내구성 및 유연성 등의 유용한 특성을 갖고 있어, 수세기 동안 다양한 분야에서 상업적인 원료로 사용되었다.Asbestos is a generic term for hydrous silicate minerals produced in an elongated form with a length of 5 μm or more and a length-to-width ratio of 3:1 or more, and has useful properties such as incombustibility, insulation, durability and flexibility, It has been used as a commercial raw material in various fields for centuries.
석면은 구성학적으로 사문석(serpentine) 계열 및 각섬석(amphibole) 계열로 나눌 수 있다. 구체적으로, 사문석 계열의 결정구조는 기본적으로 전하가 중성인 1:1층(l:1 layer)으로 구성되어 있고, 각섬석 계열은 SiO4 사면체들이 결합한 복쇄형(double chain)의 결정구조로 이루어져 있다. 사문석 계열로는 백석면(chrysotile)이 포함되며, 각섬석 계열로는 갈석면(amosite), 청석면(crocidolite), 안소필라이트(anthophylite), 트레모라이트(tremolite) 또는 악티노라이트(actinolite) 등이 포함된다. 이 중에서 백석면이 상업적 제품에 90% 이상을 차지하고 있다.Asbestos can be structurally divided into serpentine series and amphibole series. Specifically, the crystal structure of the serpentine series is basically composed of a 1:1 layer with neutral charge, and the amphibole series is composed of a double chain crystal structure in which SiO 4 tetrahedrons are combined. . The serpentine series includes chrysotile, and the amphibole series includes amosite, crocidolite, anthophyllite, tremolite, or actinolite. Among them, white asbestos accounts for more than 90% of commercial products.
1970년대 후반부터 석면에 대한 인체 위해성이 밝혀지면서 1987년 WHO 산하 국제암연구소(IARC)에서는 석면을 1급 발암물질로 지정하였으며, 우리나라에서도 고용노동부고시(제2008-26호)로 석면을 발암물질로 지정했다. 석면과 관련된 주요 질병으로는 석면폐, 폐암 및 악성중피종 등이 있다.As the dangers of asbestos to humans were revealed in the late 1970s, the International Agency for Research on Cancer (IARC) under the WHO designated asbestos as a first-class carcinogen in 1987. designated as Major diseases associated with asbestos include asbestosis, lung cancer, and malignant mesothelioma.
대표적인 석면 함유 재료로는 슬레이트(slate)가 있으며, 이는, 80 내지 90%의 시멘트와 10 내지 20%의 석면으로 구성된 것으로, 우리나라에서는 한국슬레이트 및 금강에서 대부분이 공급되고 있다. 슬레이트는 농촌 지붕개량 사업 당시 많이 사용되었고, 현재에도 전국적으로 주택과 공장, 축사 등에 사용되었던 슬레이트가 많이 남아 있으며, 점차 노후화되어 가고 있다. 슬레이트는 시멘트와 석면으로 구성되어 있기 때문에 시간이 경과함에 따라 시멘트의 구성성분인 수산화칼슘이 물에 녹으면서 석면이 주변 환경으로 방출되므로, 이들의 인체 위해성 및 환경 오염에 대한 문제해결이 필요한 실정이다. 따라서, 석면을 함유한 폐기물을 경제적으로 비산성 없이 무해화 시킬 수 있는 기술에 대한 개발이 요구된다.A typical asbestos-containing material is slate, which is composed of 80 to 90% cement and 10 to 20% asbestos, and most of them are supplied from Korea slate and Keumgang in Korea. Slate was used a lot during the rural roof improvement project, and even now, many slates used in houses, factories, and barns nationwide remain and are gradually deteriorating. Since slate is composed of cement and asbestos, calcium hydroxide, a component of cement, dissolves in water over time, and asbestos is released into the surrounding environment. Therefore, it is necessary to solve the problems of their harm to human health and environmental pollution. Therefore, it is required to develop a technology capable of economically detoxifying wastes containing asbestos without scattering them.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 석면을 포함하는 피처리물을 전처리하는 석면 전처리제 및 전처리된 피처리물을 무해화하는 석면 무해화제를 포함하는 석면 처리제를 제공하는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is asbestos including an asbestos pre-treatment agent for pre-treating an asbestos-containing material and an asbestos detoxifying agent for detoxifying the pre-treated material. to provide treatment.

상기 실시예 1에서 처리된 석면의 함량을 알아보기 위하여, 주사전자현미경(SEM)으로 분석하였으며, 그 결과를 도 1-3에 나타내었다.In order to determine the content of asbestos treated in Example 1, analysis was performed with a scanning electron microscope (SEM), and the results are shown in FIGS. 1-3.
도 1에 나타낸 바와 같이, 폐슬레이트의 석면을 확인할 수 있으며, 도 2에 나타낸 바와 같이, 석면 전처리제로 처리하였을 때 어느정도 석면이 제거되며 약화되는 것을 확인할 수 있고, 도 3에 나타낸 바와 같이, 대부분의 석면이 제거된 것을 확인할 수 있다. 이와 같이, 본 발명에 따른 석면 처리방법을 수행하는 경우 석면이 철저히 제거됨을 확인할 수 있었으며, 이는 99.999% 이상의 제거 효율을 나타냄을 확인할 수 있었다.As shown in FIG. 1, asbestos in the waste slate can be confirmed, and as shown in FIG. 2, it can be seen that asbestos is removed and weakened to some extent when treated with an asbestos pretreatment agent, and as shown in FIG. 3, most of the It can be seen that asbestos has been removed. As described above, it was confirmed that asbestos was thoroughly removed when the asbestos treatment method according to the present invention was performed, and it was confirmed that the removal efficiency was 99.999% or more.
