Title:
METHOD FOR PRODUCING PELLET MIXTURE AND RESIN MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2013/129094
Kind Code:
A1
Abstract:
Provided is a pellet mixture containing pellets that are in a uniformly mixed state, regardless of the types of materials used, even if a mixture of a plurality of types of resin pellets is mixed by shaking or blowing, for example. When spherical resin pellets and cylindrical resin pellets are mixed, the mixture is adjusted in such a manner that the excluded volume density of the cylindrical resin pellets and the bulk density of the spherical resin pellets satisfy a specific relationship. The excluded volume density is a value obtained by excluding the mass of the cylindrical resin pellets using the volume of a sphere for which the diameter represents the diagonal line of a rectangle having one side that represents the diameter of a circle at the bottom of a cylindrical resin pellet, and having one side that represents the height of a cylindrical resin pellet. The specific relationship is the bulk density × 0.6 ≤ excluded volume density ≤ bulk density × 0.8.
