Improving blowline resin blending in MDF manufacture

Chapman Kelvin M., . (2006) Improving blowline resin blending in MDF manufacture. [Proceedings Paper]

A previously described resin blending model that allows the blowline in an MDF plant to be optimised for resin blending performance has continue to be developed with new control methods that allow both the blowline and the resin atomisation conditions to be controlled at the optimum point. Significant resin savings have been archieved by the optimised blowline with other benefits such as reduced blowline and dryer cleaning also impoving plant availability. This paper reviews the history of blowline blending and attributes the reason for the higher resin requirement in some blowlines to the blowline diameter being too big to allow the required steam velocities to be achieved. This not only limits the ability to break liquid bonds between fibres in the blowlines but also the ability to use pressure atomised nozzles to produce small resin droplet. The consequence of this is to limit such a blowline to an operating area that cannot give good blending result.

Abstract

A previously described resin blending model that allows the blowline in an MDF plant to be optimised for resin blending performance has continue to be developed with new control methods that allow both the blowline and the resin atomisation conditions to be controlled at the optimum point. Significant resin savings have been archieved by the optimised blowline with other benefits such as reduced blowline and dryer cleaning also impoving plant availability. This paper reviews the history of blowline blending and attributes the reason for the higher resin requirement in some blowlines to the blowline diameter being too big to allow the required steam velocities to be achieved. This not only limits the ability to break liquid bonds between fibres in the blowlines but also the ability to use pressure atomised nozzles to produce small resin droplet. The consequence of this is to limit such a blowline to an operating area that cannot give good blending result.
