RESUMO

In the manufacturing process of adhesive tapes usually there is a step where the solvents of solution are evaporated in order to allow the formation of a semisolid layer of material over a suitable substrate. As the final product requires high coating weight and solvent concentration on adhesive solution is high as well, the drying becomes, most of the time, the constraint of the overall process. Productivity increase on machines that can produce hundred of thousands of square meters of adhesive tapes per month can represent additional sale volumes or possibility to reduce operating costs. This dissertation presents the analysis of drying process of polymeric solutions coated over impermeable substrates through the development of a mathematical model to represent the heat and mass transfer. It also proposes a methodology to achieve productivity increases using a computer code specially developed to simulate the drying process. The power of this methodology and of the computer- aided simulation is showed by a case study in the manufacturing department of adhesive tapes at 3M Brazil.
