Water Debinding for Zirconia Powder Injection Molding
Water debinding is an important debinding technique for ceramic injection molding.However cracks or blisters usually generate during water extraction.In this paper,two types of multi-component binder systems were studied:(1) a major fraction of polyethylene glycol (PEG),and a minor fraction of polyvinyl butyra (PVB) and other additives.(2) a major fraction of PEG,and a minor fraction of polymethyl methacrylate (PMMA) and other additives.Mechanism of defects generation was investigated,and PEGs with various molecular weights were introduced to avoid cracks or blisters during the process.Further more,the compatibilities of PEG/PVB and PEG/PMMA were studied.The results showed that PEG and PMMA exhibited better compatibility,with the feedstock more homogeneous and sintered ceramic parts higher strength.
