Projektbeskrivning

The fundamental aspects of dewatering between two wires is to a great extent known, but presently not accurately quantified for dewatering over multiple blades in a series. Detailed knowledge of the involved mechanisms, e.g. wave propagation on free wires, facilitates controll of dewatering and straining of the fiber suspension, which in turn can be used for controll of flock distribution and fibre orientaion. The latter factors determine the quality of the paper.
