Chrome teflonsurface coating for process rollers

Objective



A large number of varied industrial production processes currently rely on process rollers coated with Teflon to provide a non-stick corrosion resistant surface. Unfortunately the lifetime of these Teflon coated rollers in the paper, textile, paper and film converting industries is very short (< 1 year). Replacing the Teflon coating requires costly plant down time in addition to the replacement costs of the Teflon. A,s a solution to the above problems the purpose to this project will be the development of a Chrome-Teflon composite surface coating. The composite coating will comprise a chromium structure filled with Teflon cured at high temperatures to give permanent bonding. The coating will comprise the wear resistant properties of Chromium with the non-stick properties of Teflon. This will extend the lifetime of the coating by at least 10 times that of existing Teflon coatings. In summary the coating will exhibit the following properties which represent the project research goals: * A non-stick surface equivalent to normal Teflon coatings * A anti corrosion surface equivalent to normal Teflon coatings * A higher wear resistant surface able to withstand a doctoring action for longer periods * A temperature resistant surface equivalent to normal Teflon coatings * A lifetime of between 5-10 years (as opposed to existing Teflon coatings which have a 1 year lifetime) These goals will be verified through the production of a viable coating composite for demonstration in the paper, textile, paper and film converting industries.
