Summary: | Provided are an acidic cleaning composition which is an aqueous solution having pH of 3.5 to 6.5 for removing silicon-based scale; and a neutral cleaning composition having pH of 6.5 to 8.5 for removing silicon-based scale. The aqueous solution comprises at least one selected between a fluorosilicon compound and ammonium bifluoride (NH_4HF_2). The cleaning solution can remove silicon-based scale, hardness component scale, metal component scale, etc., at the same time, thereby having a simple process without having a separate alkali cleaning process while having excellent effect of cleaning.
본 발명은 불화규소화합물 및 중불화암모늄(NHF.HF)에서 선택된 하나 이상을 포함하는 수용액이며, pH가 3.5 내지 6.5인 실리콘계 스케일 제거용 산성 세정액 조성물 및 pH가 6.5 내지 8.5인 실리콘계 스케일 제거용 중성 세정액 조성물을 제공하며, 이러한 세정액으로 실리콘계 스케일과 함께 경도 성분 스케일 및 금속 성분 스케일 등을 동시에 제거하여, 별도의 알칼리 세정 공정을 거치지 않아 공정이 간단하고, 세정효과도 우수한 효과가 있다. |
