| Résumé : |
Inkjet printing has emerged as a most effective method for applications such as tile decoration, where it efficiently delivers high definition patterns and images to a variety of non-flat ceramic substrates. Realising these benefits relies on developing ink formulations with a rheological profile that is well-matched to ail the conditions experienced during the printing process. A successful ink will resist sedimentation under the gravitational stresses that apply during storage, while simultaneously meeting exacting flow targets under the extremely high shear rates generated within an inkjet print head.
Rotational rheometry is a widely used technique for formulation characterisation, capable of delivering accurate rheological data over a broad range of shear rates. However, the mechanical and sample limitations of rotational rheometers are problematic when it comes to measuring at the ultra-high shear rates that prevail within a print head. Under these conditions the relatively new technique of microfluidic rheometry has proven value. |
