Abstract

PURPOSE: To prevent over-deterioration of a material as well as to enable to disperse the same in an extremely high degree by a method wherein a ratio of a respective blade length of a movable blade and a stationary blade and a flow passage between blades is set in a specific range as well as the movable blade and the stationary blade are alternatively arranged in plural stages.
CONSTITUTION: When a barrel 10 of an extruder is heated and resin material 14 is thrown thereinto from a hopper 13, the material 14 is moved according to rotation of a screw 5 and converted to an almost molten liquid form until reached to a leading end 9 thereof. The material flowed into a stationary blade 3' loses a circumferential speed because a blade length is sufficiently long compared to a distance between blades and advanced to an axial direction. In this case, when a blade row of a first stage comprises movable blades 3, even if the material passes the movable blade row, dispersion is not generated. When the material entered into the movable blade from the stationary blade, a blade length 1 related to a width w of a flow passage between blades may be adjusted to a formula 1/w≥0.5.
