Steel and iron chemical oil removing
powder comprises, by weight, 5-10 g of
sodium hydroxide, 40-50 g of
sodium carbonate, 0.5-1 g of EDTA disodium, 8-10 g of
sodium tripolyphosphate, 1-2 g of a washing assisting agent, 20-30 g of a
metal protecting agent and 5.5-8.5 g of a surface
active agent. A preparing method of the oil removing
powder includes the following steps that
sodium hydroxide,
sodium bicarbonate, EDTA disodium and sodium tripolyphosphate are mixed and stirred uniformly so that A
powder can be obtained; and the washing assisting agent, the
metal protecting agent and the surface
active agent are added into the A powder at a time, and after uniform stirring is performed, the finished oil removing powder can be obtained. A using method of the oil removing powder includes the following steps that
warm water is added in a cleaning tank, and temperature is 40-70 DEG C; and 4-8% of the oil removing powder is added into the
warm water and is stirred till complete dissolving is achieved. The surface of steel and iron cleaned through the oil removing powder is free of a visible
oil film or oil spots, meanwhile, the using amount of the oil removing powder is small, and the steel and iron chemical oil removing powder is economical, non-toxic and environment-friendly.
