摘要

On-line gauging Systems provide timely and valuable insights into the Coating process with Process Analytical tools and Process Diagnostics Visualization tools. Though the On-line gauging systems' role in Coating Measurement and Control is well known, their crucial role in trouble-shooting the Coating Process is not well understood. This paper focuses on the application of the tools such as FFT, Contourview, Process variables trending etc. to pinpoint the coating process problems in a timely manner. The system monitors a multitude of process variables continuously and trends the data for process monitoring. Time-based trends of various temperatures, pressures and speeds can be displayed continuously, along with coating thickness to show cause and effect. The high degree of process visibility is of tremendous value to the Line Operators and Process Engineers to setup the equipment at start-up and product changes, as well as to monitor production continuously. System ensures full-width coating gauge uniformity through effective process controls in the cross and down web directions, while monitoring substrate variability. The resultant Process Optimization contributes significantly to improved product quality, increased productivity, scrap reduction and coating material yield. The impact on coating production economics is verv significant.
