In this paper, a wax-based binder was developed for low-pressure injection molding of very fine (0,4 μm) average particle size alumina ceramic bodies. The major component used in the binder mixture was paraffin wax. The process of binder removal from the green ceramics presented several difficulties especially when the ceramic powder was very fine, and the pieces had large cross-section. The pr...

Absorption of cobalamin free or bound to chicken serum was assessed in nine patients with pancreatic insufficiency. Simultaneously the in vitro effect of duodenal juice collected from six patients and seven controls was tested on labelled cobalamin complexed to chicken serum or to R salivary binder. Malabsorption of free cobalamin was observed in one of nine patients and in four of nine patient...

Thermobonding is widely used in producing of nonwovens. In this study various layers of thermobonded nonwovens were produced by altering the pressure, binder fibres and quality of blending. Mechanical properties of the so-called layers such as breaking strength and breaking elongation, bending rigidity and air permeability were assessed consequently. The structure of the layers was then studied...

Three binders, polyvinyl alcohol (PVA), polyvinylpyrrolidone, and polyacrylic acid (PAA), are studied to elucidate the principal fundamental features giving rise an excellent binder in a polymer–stainless-steel particle array, used context of jetting. Using out-of-printer screening approach, samples were compared based on compression tests, specifically 0.2% yield strength as function void volu...

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...

In this paper, we present a declarative language and system for describing and implementing secure networks. Our proposed language, SeNDlog, is an attempt at unifying Binder, a logic-based language for access control in distributed systems, and Network Datalog (NDlog), a database query language for declarative networks. The contributions of this paper are as follows. First, we highlight the sim...

The aim of this article is to test the properties of foundry moulding sands with a new bicomponent organic binder. The new binder is the composition of phenol-furfuryl resin, commonly used in foundry practice and biodegradable material – polycaprolactone. The paper presents the research of strength properties, thermal destruction and thermal deformation of moulding sands with a new bicomponent ...

This paper reports the substitution of polyolefin backbone binder components with low melting temperature carnauba wax for powder injection moulding applications. The effect of various binder compositions of Al₂O₃ feedstock on thermal degradation parameters is investigated by thermogravimetric analysis. Within the experimental framework 29 original feedstock compositions were prepared and the s...
