DRYING OF PAINTED GLASS PLATE ON MOVING TAPE

ABSTRACT
While moving on the tape, the surface temperature of the painted glass plate entering the drying oven reaches a required certain temperature after a certain distance. The drying air as reverse flow through the product is directed transversely across the other end of the drying oven and towards the inlet. The convective mass transfer between the surface and the free flow depends on the conditions within the boundary layer. The relationship between convection mass transfer and concentration boundary layer are explained with valid equations for mol flux related to diffusion mass transfer. In the study, drying oven and air conditioning cabin has been used to determine the drying properties of two types of tempered glass paint of 1T1405-IR702 and 1T1430-IR702. In the drying process on conveyor tape, the drying oven length has been determined between 5.30 m and 23.3 m for values of conveyor tape velocity of 0.05 m/s, drying temperatures between 50°C and 70°C and forced air velocity of 2.5 m/s. At the end of the study, the theoretical and experimental results have also been evaluated.
