WRATT II Solvents - The Good, the Bad & the Banned Chapter 01: Alkaline Cleaning in Parts Washing Systems
Chapter Abstract: This is clip 1 of 6 for this video. The removal of soil can be achieved by way of detergency, solvency, chemical reaction or mechanical action. Alkaline cleaners are made of three components; builders, surfactants and additives. The builder is and alkaline salt that adds alkalinity, disperses soil and acts as an inhibitor. Surfactants are organic compounds that provide detergency and wetting action. Additives are used to provide water softening, rust inhibiting, etc. There are three mechanisms used to achieve alkaline cleaning, saponification, emulsification, and dispersion. Dispersion is the best of the three options. The two main types of washing systems are spray and immersion. Alkaline cleaning works for a variety of materials in a variety of industries. Alkaline cleaners have some challenges facing them before they gain widespread acceptance.
