Thermosetting Material
Soak the plates and cages in a suitable solvent to
separate and clean them.
or
Heat the parts to red heat in the oxidizing portion
of a burner flame. The organic material should
oxidize completely.
or
Heat the plates in a furnace to approximately
1000°C.
Calculations
Correction Calculations for Thermal
Expansion of Parallel Plates
1. Calculate the apparent distance between the
plates ( h* ) at a given temperature (or time)
by subtracting the decrease in distance
between the plates (in mm) from the original
sample height.
Equation:
h* = sample thickness – dimension change
(mm) (mm)
2. Correct the distance between the plates for
thermal expansion.
Each plate is nominally 5.08 mm (0.2 inch)
stainless steel. Therefore, the total dimension
for both plates is 10.2 mm (0.4 in.).
