Between usually (for example, first duration).As previously mentioned, if the excessively smooth final shell finished product of binder course 12 will will appear rainbow
Line can be excessively smooth to avoid binder course 12 by controlling the flow time of binder course 12 in relatively short duration, in turn
Avoid the appearance of rainbow line.In particular, present inventor chances on, when the first duration is less than the half of the second duration,
Hardly there is rainbow line in shell finished product.
In the present embodiment, titanium dioxide is adulterated by the doping silicon dioxide particle in colored paint layer 15 and in top coat layer 16
Titanium particle can achieve the effect that increase shell projectiveness since the refractive index of titanium dioxide and silica differs.In addition, two
