초록

본 연구에서는 유기산, 무기산, 여러 첨가제들을 이용하여 옥내급수관의 스케일 제거에 적합한 환경친화적인 세정제를 개발하고자 연구를 수행하였다. 여러 유기산 중에서 oxalic acid, citric acid, malic acid 등의 경우 산화철 제거에 비교적 좋은 효율을 보였다. 이들 유기산들을 주축으로 하여 보조제를 첨가하여 옥내급수관 스케일의 주성분인 산화철 제거 평가실험을 하였다. 여러 첨가제 중에 비이온 계면활성제가 산화철 제거력 향상에 매우 뛰어남을 확인할 수 있었다. 그리고 산화철에 대해 높은 용해력을 보인 두 종류의 배합세정제 F1과 F2 를 제조하였는데 배합세정제 F1의 경우 유기산과 첨가제로만 이루어져 있어 기존의 화학세척제에 비하여 안전하고 환경친화적이지만 비교적 산화철 용해력이 조금 떨어졌고, F2의 경우는 F1에 무기산을 소량 첨가함으로 산화철 용해력을 보완해 줌으로써 보다 높은 산화철 세정력을 필요로 할 때 사용하는 것이 좋을것으로 판단된다. 따라서 옥내급수관 세정 시 스케일의 정도에 따라 배합후보 세정제를 선택하는 것이 바람직하다고 판단된다.

The objective of this study is to develop cleaning agents for the indoor water supply pipe which is environmentally friendly and suitable for removing scale by using various organic acids, inorganic acids, and some additives. Among various organic acids, oxalic acid, citric acid, and malic acid showed good cleaning efficiency of iron oxides which were main components of the indoor water supply pipe scale. Several cleaning agents were formulated by adding chemical additives into these organic acids and evaluated for removal of iron oxides. In this study, it was found that nonionic surfactants were excellent for the removal of iron oxide scale among various additives. Two types of cleaning agents(F1, F2) with comparatively high solvent power for iron oxides were formulated in this study. The cleaning agents F1 made by organic acids and some additives were formulated to be safe and environmentally friendly, but seemed to have disadvantage due to their comparatively low cleaning efficiency of iron oxide than F2. But, the cleaning agents F2 prepared by adding inorganic acid a little to F1 showed comparatively good cleaning efficiency of iron oxide and could be recommended for removing hard scale of iron oxides in the indoor water supply pipe. Thus, it is considered that the formulated cleaning agents should be selected based on the extent of scale in the indoor water supply pipe.
