Description

This paper discusses the effects of water quality on three classes of soluble wiredrawing lubricants—emulsifiable/soluble oil type, semi-synthetic, and synthetic. Discussion includes water as defined by physical and chemical parameters such as pH, hardness, conductivity, ionic content, and biological activity. It also examines water types and their sources such as municipal, hard, soft, and reverse osmosis, as well as their effects. The paper offers parameter range limits in an effort to yield optimum lubricant performance.
