Title:
POWDER PARTICLES AND PROCESS FOR PRODUCING GREEN WORK USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/099250
Kind Code:
A1
Abstract:
[Problem] To provide: powder particles for forming a green work which has sufficient strength and is homogenous; and a process for producing a green work using the powder particles.
[Solution] Powder particles that are composite particles which comprise base particles and thermoplastic-resin particles scatteringly present on the surface of the base particles in an amount within a predetermined range of volume proportions with respect to the base particles and in which the thermoplastic-resin particles are supported by the base particles so that in cases when the thermoplastic-resin particles melt, the resin melt gathers around the contact points between adjoining base particles while leaving spaces in regions other than the regions around the contact points. Use of these powder particles makes it possible to form a green work in which the powder particles have been packed, each powder particle being in the state of having a small amount of the thermoplastic-resin particles adherent thereto. When the green work is placed under conditions where the thermoplastic-resin particles melt, the thermoplastic resin melts and the resin can be gathered around the contact points (adjoining points) between adjoining powder particles. Due to this, the bonding force among powder particles can be effectively improved with an extremely small amount of a thermoplastic resin, and a tenacious green work having no strength unevenness can be obtained.
