Abstract

PURPOSE:To make it possible to mix a main gredient and a liquid additive evenly, by using a single-fhaft screw extruder in which the depth of the screw groove part near the liquid injection port is made shallower than that of the measuring part of the extruder. CONSTITUTION:A liquid additive is injected into the extruder from liquid injection port 3 and is mixed with resin fed from hopper 4. Here, since the depth W of the screw groove part near the place where the liquid additive is injected is formed shallow, the flow of resin becomes extremely fast, so that the liquid additive does not stay in the part rising in the back from the bottom surface of the groove and it is dispersed into resin evenly.
