制造业中的环境负荷是一个备受关注的问题。在加工现场，使用切削油、磨削液等金属加工液(冷却液)。它含有油、表面活性剂、极压剂、防锈剂、消泡剂、防腐剂、杀生剂等多种化学品。人们认为它对环境和人体都不好。加工液雾和飞溅中含有多种化学物质，在加工过程中会对工人的健康造成危害。此外，随着时间的推移，液体会被细菌腐烂。会产生难闻的气味和加工性能的下降。因此，在使用加工液后，废液被处理。需要焚烧或混凝沉淀和填埋等。温室气体(CO2等)的大量排放带来了巨大的处理成本和环境负荷。于是，在工业上就需要减少或不使用加工液。为此，本研究开发了一种新的环保型加工方法--仅以水为加工液的电防锈加工方法体系。本文介绍了水加工系统开发中的水净化循环系统。因此，在不使用杀生剂等化学物质的情况下完全清除细菌(产气肠杆菌)是为了防止腐败、防止恶臭和安全加工水。
It is great concern that is environmental load in manufacturing. In machining site, metal working fluid (coolant) such as cutting oil, grinding fluid is used. It contains several chemicals that are oil, surface active agent, extreme pressure additive, antirust agent, antifoaming agent, preservative, biocide etc.. It is thought that it is not good for environment and human body. Machining fluid mist and splash contained several chemicals that are cause of danger for worker’s health while machining. Furthermore, time elapses, fluid is rotten by bacteria. Bad smell and degradation of machining performance occurs. Therefore, after using machining fluid, waste fluid is disposed. Incineration or coagulative precipitation and landfill etc. are necessary. It arise great disposal cost and environmental load as discharging of huge amount green house gas (CO2etc.). Then, machining fluid decreasing or non-using is demanded in industry. So, in this investigation, new environmental machining method: the electric rust preventive machining method system that uses only water as machining fluid has been developed. In this paper, water purification recycle system in water machining system development is mentioned. Therefore, complete removal of bacteria (Enterobacter aerogenes) without using chemicals such as biocide is examined for corruption, malodor prevention and safe machining water.
