中文摘要

Response surface methodology (RSM) was used to analyze the effect of
glycerol level (X1) and EAA level (X2) on the objective (water solubility
index, water absorption index, and Max. loading) attributes of a PVOH/starch
blended plastic resin. A rotable central-composite design (CCD) was used to
develop models for the objective responses. The experiments were run with
different barrel temperatures such as zone 1:100?, zone 2:100?, zone
3:105? and zone 4:105?, respectively with a feed rate of 20g/min, and screw
speed 25 rpm. Responses were most affected by changes in glycerol level (X1)
and to a lesser extent by EAA level (X2). Individual contour plots of the
different responses were overlaid, and regions meeting the optimum water solubility index of 6.10? ? ?, water absorption index of 5.57? g gel/g dry wt?,
and Max. loading of 62.14? N? were identified at the glycerol level of 72.41
? ml? and the EAA level of 36.03? g? , respectively.
