一、问题的提出水剂合成切削液是机械行业目前迫切需要的产品。本文所指的水剂合成切削液是完全不含油的,也称透明切削液。以往配制一吨乳化油需用机油600～800公斤,既浪费能源,又污染环境,且冷却性和清洗性都较差,其防锈性则靠添加亚硝酸钠来实现。而亚硝酸钠是有毒物质,长期接触对人体有致癌的危险。随着化学工业的发展,目前以水剂作为冷却介质的透明切削液已不是以往书本上所介绍的、由亚硝酸钠,碳酸钠或磷酸三钠及聚乙二醇组成的简单水溶液了。因为这种类型的透明切削液虽有良好的冷却性和一定的防锈性,但润滑性和极压性都较差,而且防锈剂也没有跳出亚硝酸钠的框框。研制具有良好性能的水剂切削液,在一些工业发
First, the issue put forward Aqueous liquid synthetic cutting fluid is currently urgently needed machinery industry products. This article refers to the liquid synthetic cutting fluid is completely free of oil, also known as transparent cutting fluid. The past preparation of a ton of emulsified oil need oil 600 ~ 800 kg, both waste of energy, but also pollute the environment, and cooling and cleaning are poor, and its rust by adding sodium nitrite to achieve. The sodium nitrite is a toxic substance, long-term exposure to the human body is carcinogenic risk. With the development of the chemical industry, the transparent cutting fluid currently used as a cooling medium is no longer a simple aqueous solution composed of sodium nitrite, sodium carbonate, or trisodium phosphate and polyethylene glycol as described in previous books. Because this type of transparent cutting fluid, although good cooling and a certain anti-rust, but poor lubricity and extreme pressure, and rust-proofing did not jump out of the frame of sodium nitrite. Development of liquid cutting fluid with good performance, in some industrial hair
