STRONGLY ALKALINE IONIZED WATER AND METHOD OF DEFATTING/RUSTPROOFING

摘要

[PROBLEMS] To provide a method of defatting/rustproofing that is environmentally friendly, ensures high safety and excels in detergency and rustproofing effect. [MEANS FOR SOLVING PROBLEMS] Only a strongly alkaline ionized water of 12 or higher pH produced by strong electrolysis without the use of any pH accelerator is sprayed over metal parts, or alternatively metal parts are immersed in the strongly alkaline ionized water. [EFFECT] Defatting/rustproofing is carried out only by a strongly alkaline ionized water of 12 or higher pH produced by strong electrolysis wherein none of chemicals and solvents is contained, so that while exerting excellent detergency and rustproofing effect, there can be attained environmental friendliness and high safety.
