Zusammenfassung:	PURPOSE: A low temperature agent for removing grease and a method for removing grease in strip by using thereof are provided. CONSTITUTION: The method includes the steps of pouring a degreasing agent comprising sodium gluconate 22 to 30 wt.%, diethylglycol monobutyl ether 22 to 30 wt.%, hexamethylene tetramine 2 to 3 wt.%, EDTA-4Na 2 to 3 wt.%, defoamer 1.5 to 2 wt.%, potassium hydroxide 1 to 3 wt.% and a balance of non ionic surfactant into a strip degreasing solution in an amount of 0.18 to 0.22 %; and feeding a strip into the strip degreasing solution at 58 to 62°C. 본 발명은 저온탈지제 및 그것을 이용한 스트립 탈지방법에 관한 것으로, 소디움글루코네이트 : 22~30%, 디에틸렌글리콜 모노부틸에테르 : 22~30%, 헥사메틸렌테트라민 : 2~3%, EDTA-4Na : 2~3%, 디포머 : 1.5~2%, 포타시움하이드록사이드 : 1~3% 및 잔부 비이온계 계면활성제로 구성되어 비누화작용 및 유화작용이 향상된 저온탈지제를 제조한 후 이 저온탈지제를 스트립 탈지용액 원액양의 0.18~0.22%로 첨가한 후 58~62℃에서 스트립을 탈지하도록 한 것을 특징으로 한다. 본 발명에 따르면, 저온탈지제를 적정온도조건에서 사용함으로써 환경적 위해 인자를 줄이고 고온에 의한 안전사고를 방지할 수 있으며 온도조정에 의한 에너지 절감효과를 얻을 수 있다.
