Additive Manufacturing of Casting Tools Using Powder- Binder-Jetting Technology
This chapter presents the use of the additive manufacturing (AM) method powderbinder-jetting (PBJ) for the generation of molds and cores for casting applications. Theoretical information on process steps and the binding of particles is given. For the based chemistry, examples are presented and the transfer from conventional produc‐ tion processes to powder-binder-jetting is explained. For sand ...
متن کاملAluminium hydroxide versus sucralfate as a phosphate binder in uraemia.
In an attempt to discover a phosphate binding agent for use in uraemia that would not lead to appreciable systemic absorption of aluminium the effect of sucralfate was evaluated after three weeks and compared with that of the existing standard agent aluminium hydroxide. Sucralfate caused a decrease in serum phosphate concentration comparable with that obtained with aluminium hydroxide, but simi...
متن کاملThe Effect of Binder Components and Powder to Binder Ratio on Rheological Properties of Mg-SiC Feedstocks
Rheological characteristics of powder injection molding PIM feedstocks play an important role in final properties of manufactured MMCs. In this study, six formulations composed of magnesium and SiC powder (99:1 wt.%) and a specific binder were prepared to investigate the influence of binder composition, powder to binder ratio, time and temperature on rheological properties of the feedstock. Th...
متن کاملSilica sulfuric acid as an efficient and reusable heterogeneous catalyst for the synthesis of formamidines from the diaminomaleonitrile
Silica sulfuric acid as an efficient and reusable heterogeneous catalyst has been used for the preparation of amidines 2 from formimidate 1 by reaction with aromatic amines at room temperature in good to excellent yields. Imidate was prepared by treatment of equimolar quantities of triethyl orthoformate and diaminomaleonitrile in refluxing dioxane. All the compounds were characterized fully by ...
