Poly alkylene glycol (PAG) practical implementation in the production environment

摘要

Water-based polymer solutions are being used in an increasing amount in the metal industries for both safety and environmental reasons. In addition, the aqueous polymer solutions give superior results in many cases. The use of poly alkylene glycol (PAG) solutions to minimize quenching distortion in the aluminum industry is an excellent example. With proper control the new solutions can also be as or more economical than the older formulations. In order to be effective and economical, aqueous polymer solutions require proper maintenance to perform as advertised. The implementation of the polymer into a production facility requires more than just buying the polymers and adding them to the quench tank. In this paper specific topics that users need to understand and control in order to maximize the performance of these solutions will be presented. They are: · Facility changes · Concentration Control · Bath/Solution Conditioning · Reclamation · Equipment · Benefits/Economies · Future Developments In what follows these are discussed in order.
