Overdosing of Expensive Dye in Viscous Resin

Problem

Overdosing of Expensive Dye in Viscous Resin: Costly overdosing of dye in colour coded particle board manufacture resulted in unnecessary loss of profit. Spanboard, manufacturers of multigrade woodchip particle board, used colour coding for grade identification.

The colouring was achieved by the addition of dye to the resin which bound the woodchip particles. It was suspected that overdosing was inadvertently being used to compensate for poor mixing due to the high viscosity of the resin and laminar flow.

Solution

Overdosing of Expensive Dye in Viscous Resin: Statiflo was called in to investigate the problem and identify a solution.

Excessive dye dosing was indeed taking place as a means of compensating for poor mixing and Statiflo recommended the installation of a 25mm diameter 6 element Motionless Mixer at the dye injection point.

Result

The result of the Statiflo Solution for the problem of Overdosing of Expensive Dye in Viscous Resin resulted in the following:

• A dramatic reduction in dye usage ensued.
• In the first year a saving of £44,000 on dye costs was achieved.
• The Statiflo Motionless Mixer cost less than £300.
