도시화 기계화가 급속히 발전하면서 문에 보이는 오수처리 기술 폐수처리 대기오염 방지, 소음진동 방지에 관계된 기술이나 제품은 그 기술 수준이나 제품의 고급화를 이루어지고 있지만 제3의 공해라 불리는 전자파 즉, 전기자와 자기파를 흡수 및 차폐분에서는 실용이 안되고 있는 현실에 직면해 있다.Sewage treatment technology seen in the door due to the rapid development of urbanization mechanization Technology and products related to wastewater treatment air pollution prevention and noise and vibration prevention have been advanced at the technical level or product level, but electromagnetic waves called the third pollution, namely electric and magnetic In the case of absorbing and shielding waves, there is a reality that is not practical.
도 1에 도시된 바와 같이, 일반적으로 도심속에서의 전자파 발생원인으로는 전신주(2)를 통하여 거미줄처럼 연결되어 있는 전선케이블(1)이 원인이며, 이러한 전선케이블(1)이 주택 밀집지역에 고압 전선의 위험성 때문에 주민의 민원의 원인이 되었으며, 전선케이블이 공사장에 옆을 통과할 때에는 감전 방지용으로 황색 방호관을 부착하여 위험성을 저감시키고 있는 현실이다. 또한, 지하철 플랫홈에서 전동차에 전원을 공급하는 전선케이블의 경우에는 감전을 방지하기 위한 보호관으로 폴리에틸렌 등의 방호관을 부착하여 감전을 방지하였으나 전선케이블에서 발생되는 전자파 자체를 차단할 수 없는 문제가 있다.As shown in FIG. 1, the cause of electromagnetic wave generation in the city in general is caused by a wire cable 1 connected like a spider web through the telephone pole 2, and the wire cable 1 is located in a dense residential area. Due to the danger of high-voltage wires, it became a cause of civil complaints, and when the wire cable passes through the construction site, a yellow protective tube is attached to prevent the electric shock, thus reducing the risk. In addition, in the case of the electric wire cable for supplying power to the electric vehicle in the subway platform to prevent electric shock by attaching a protective tube such as polyethylene as a protective tube to prevent electric shock, but there is a problem that can not block the electromagnetic waves generated from the electric wire cable itself.

In this case, it is preferable to use Cu-Ti-Mn low-temperature sintered ferrite, Ni-Zn ferrite, or the like.
제 2 공정 : 방호관용 혼합물 형성단계Second Process: Mixture Forming Step for Protective Tubes
전체중량을 기준으로 제 1 공정에서 세라믹 나노파우다 30 내지 50중량%와, 열가소성 합성수지 30 내지 50중량%와, 디옥틸프탈레이트(DOP ; dioctyl phthalate), 디옥틸아디페이트(DOA), 트리크레실포스테이트(TCP) 등의 가소제 20 내지 40중량%를 실온의 대형 믹서기에 혼합(Blending)한다. 이때, 열가소성 합성수지 30중량% 이하로 첨가하면 제조되는 방호관이 쪼개지거나 깨지는 단점이 있으며, 70중량% 이상 첨가하면 세라믹 나노파우다 또는 가소제의 함량이 감소되어 제조된 방호관의 전자파 차폐능력이 감소되는 단점이 있다.30 to 50% by weight of ceramic nanopowder, 30 to 50% by weight of thermoplastic synthetic resin, dioctyl phthalate (DOP), dioctyl adipate (DOA), and tricresyl formate in the first process based on the total weight 20 to 40% by weight of a plasticizer such as (TCP) is blended into a large-sized mixer at room temperature.
