It is important to bear in mind that with different thickness of cast film produced, incubation time, or lipase concentration, the range may shift depending on the enzymatic rate and substrate amount beneath the lipase droplet.
Mathematical modeling of phase inversion membrane fabrication has been focused by many researchers, as the experimental study of phenomenological events is almost impossible, mainly, due to the high rate of exchanges and the small thickness of cast film.
Casting speed was maintained by the computerized program and casting thickness was maintained by lifting casting blade above the fabric up to a specified height using a pair of micrometers attached at the two ends of casting blade.
Microstructure investigation, tensile, hardness and wear rate measurements have been correlated with the size and percentage of SiC particles and their distribution/gradient across the thickness of the cast tubes resulting from the used casting parameters.
The thickness of the cast is built by offsetting the cast surface.
The results of tensile testing indicate that the tensile properties including yield strength (YS), ultimate tensile strength (UTS) and elongation (Ef) decreases with increasing section thicknesses of die cast AM50.
The thickness of the cast membrane was measured using a micrometer (Mitutoyo, Japan).
Thickness of the cast is modelled in the last step overset{rightharpoonup }{p^{prime }}=overset{rightharpoonup }{p}+tcdot {overset{rightharpoonup }{n}}_{pi} (3).
It is however notable that the range hereby reported is only applicable to the thickness of film as casted in this study.
Gels of 18-27 μm thickness were casted by using 6 9 μL of pre-polymer solution.
SDS polyacrylamide gels 11-166% [w/v]) of 1.0 mm thickness were casted with the a 2DEoptimizer (Biometra, Göttingen, Germany).
