IMPROVEMENT OF RHEOLOGICAL AND SHAPE RETENTION PROPERTIES OF WAX2BASED MIM BINDER BY MULTI2POLYMER COMPONENTS①
Trans. Nonferrous Met. Soc. China Mar. 1999 Vol. 9 №.1,-0001,():
The rheological and shape retention properties of wax2based binders with different polymer components were studied. The effects of different polymer components on rheological, shape retention and me-chanical properties, and isotropic dimension shrinkage were investigated. The feedstock based on the PW-PP binder can not be used for injection molding due to severe separation of the binder from metal powder. The general rhelogical properties of the Fe-2Ni feedstock based on the PW-EVA binder were superior to that of the Fe-2Ni feedstock based on the PW-HDPE binder, while the shape retention properties of the PW-HDPE binder were superior to that of the PW-EVA binder. By the combination of EVA and HDPE as multi-polymer components, the PW-EVA-HDPE binder should have the best rheological and shape retention properties. The shrinkage homogeneity and mechanical properties of the feedstock based on this binder were also the best.
