Abstract.This chapter describes the processes of knife and roll coating from a fluidmechanical point of view.It combines a critical review of what is known, along with some speculation aimed at stimulating new lines of research.
Knife coating.Variation of the coating weight roller knife 10 to 1.250 gm 2 air knife 56 to 60 gm 2 range of viscosity mpas paste 1000 100 50 000 foam 10 000 25 000 air knife.
The feed head and or a coating distribution method within the coating in the hopper are important depending on the coating to help prevent coating defects and thickness variations.Knife over roll coaters are ideal for high viscosity coatings as well as applications with high coat weights.
The machine comprises an unwinder, corona treater arcotec, air knife static discharger, coating unit, hotair dryer, cooling roller and rewinder.In addition, the system is equipped with four video cameras, enabling online monitoring and control of the process.
