3.3 Effects of Input Parameters on PE Wax
Microparticle Determination
The results from the Taguchi method
analysis are shown in Table 2.
In contrast to the results of the atomization
of molten polyethylene glycol where the
flow rate has the most important effect on
particle size [20] as can be seen from Table 2,
the atomizing temperature has the strongest
effect on the percent yield similar to that of
the interaction between the air pressure and the
DA/DL ratio, since the percentage of the PE
wax microparticles smaller than 200 μm was
increased to 6.28% by changing the temperature
(average percent yield at T1 - average percent yield
at T2) or by changing the interaction between
the air pressure and the DA/DL ratio (average
percent yield at P1R1 and P2R2 - average percent
yield at P1R2 and P2R1). This may be caused
