Description

Metal powder gel injection molding device

Technical Field

The utility model relates to the technical field of gel casting, in particular to a metal powder gel casting device.

Background

In the nineties of the twentieth century, professor M.A.Jenny and O.O.Omatete of Oak Ridge National Laboratory) in the American Oak Ridge state have provided a new ceramic material wet forming technology, gel injection molding technology (Gelcasting), which is a perfect combination of traditional grouting process and organic chemistry high polymerization theory, and the traditional grouting forming process is developed by introducing a new shaping mechanism. The basic principle is that low-concentration organic monomer and cross-linking agent are mixed into ceramic slurry with high solid content (volume fraction not less than 50%) and low viscosity (about 1 Pa.s), and after initiator and catalyst are added and cast, the organic monomer in the slurry is in-situ polymerized under a certain condition to form a firm three-dimensional network structure, so that the suspension is in-situ cured and formed to obtain a uniform, high-strength and near-net-size ceramic body. Since the polymerization degree of the monomer is high and the molecular weight of the organic substance formed is large, it is difficult to completely remove the organic substance during sintering. For metal powder, residual carbon will react with the powder to form carbide, hindering the sintering process and making the material brittle, so the study of low carbon residual gel system is crucial for gel injection molding of metal powder
