| Résumé : |
Powder coatings are considered as the "best available control technology" for environmental and ecological balance and control in the paint and coatings industry. However, they are not popular as a choice for high aspect finishes comparable to liquid paints, due to inherent orange peel and lower gloss levels on 20 deg gloss head. The current research study uses the Taguchi design of experiments to gain an insight into the factors that are responsible for the improvement in gloss levels at 60-degree and 20-degree gloss head in powder coatings. Also, the resins chosen for the study were suitable as "fast-curing" type so that when used online, the length of the oven can be considerably reduced resulting in better energy savings for the applicator.
The Taguchi Design method, also called the Robust Design Method, greatly improves engineering productivity. Taguchi Design method helps ensure customer satisfaction. Robust Design focuses on improving the fundamental function of the product or process, thus facilitating flexible designs and concurrent engineering. The statistical too employs the methodology of signal to noise ratio and its importance in determining significant factors was demonstrated. The factors of type of polyester, type of catalyst used and amount of extender, were established to be more significant than other identified factors. Interactions between the type of catalyst used and type of polyester used were also observed, and a probe into the reason for interaction was made. The extender amount was also observed to independently affect gloss values. Indeed, it is one of the most powerfull methods available to improve quality, reduce product cost, and simultaneously reduce development interval. |
