bath, either on the surface or at the base of the bath, depending upon the density of the material
involved. If this happens it is recommended that the bath be checked and cleaned at least once
a week or more frequently if the bath is used continuously.
The following table details recommended operating temperatures for particular
polymers. The temperatures quoted should be used as an initial guide.
The ideal operating temperature will vary depending on the size of the components
being cleaned and the amount of material being removed. In general temperatures below
400°C should be avoided to obviate the danger of the polymer melting and sinking to the bottom
of the bath where it may block the porous plate. With some large objects it may be desirable to
preheat the bath to well above the operating temperature so that the polymer temperature
rapidly moves through the melting phase to the burning condition.
Excessive operating temperatures should be avoided as they increase the fume
concentration above the bath and may result in the formation of condensed fumes within the
extraction system.
