CENTRIFUGAL MOLD, MANUFACTURING METHOD THEREOF, CENTRIFUGALLY MOLDED OBJECT PRODUCED BY THEM, BLADE AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To solve the problem that the peeling of a centrifugally molded object is difficult if a release agent is not used in a conventional centrifugal mold, the number of times in repeatedly moldable use is small and regeneration is also difficult. SOLUTION: The centrifugal mold is equipped with a cylindrical mold main body 11, the holding layer 13 bonded to the inner peripheral surface 12b of the mold main body 11 in a releasable manner and a release layer 14 integrally bonded to the inner peripheral surface 13a and holding a supplied centrifugal molding material on its inner peripheral surface in a peelable manner. A first liquid agent for constituting a holding layer 13 is supplied to the inner peripheral surface 12b of the mold main body 11. The mold main body 11 is rotationally driven so as to uniformly diffuse the first liquid agent to the whole region of the inner peripheral surface 12b of the mold main body 11 and the first liquid agent is cured to form the holding layer 13. A second liquid agent for constituting a release layer 14 is supplied to the inner peripheral surface 13a of the holding layer 13 in order to constitute the relase layer 14. The mold main body 11 is rotationally driven so as to uniformly diffuse the second liquid agent and the second liquid agent is cured to form the release layer 14. COPYRIGHT: (C)2004,JPO
