Converting To Waterbornes

摘要

An often unstated goal when converting a coating application system to water-bornes is to disrupt "the way it's done now" as little as possible, particularly if the existing system has good equipment and is performing well. That goal is not out of reach because the existing process, and much of the existing equipment, can often be used for waterbornes. Usually only the atomizers will need to be modified for waterbornes, or replaced with atomizers specifically designed to handle waterborne materials. The remaining equipment and distribution system can be reused unless made of materials that will corrode in waterbornes or be damaged by exposure to them.rnWell-engineered conversions from solvent-based coating materials to waterbornes result in the highest possible operating efficiency at low cost and with maximum operator safety. The operating cost, in terms of TE, should be about the same as that of a good solvent-based paint system. To get high TE, electrostatics must operate at peak efficiency. This means directly charging the material with electrostatic voltage, but limiting the hardware that gets charged.
