Coating Materials

Application and Preparation of Enteric Coating Materials

In this paper, polymethacrylate enteric coated materials based on the equal mass of methyl acrylic acid and ethyl acrylate as the main raw materials were synthesized through emulsion polymerization. Omeprazole Enteric-coated Capsules were prepared by the fluidized bed coating technology using above materials as enteric layer and in vitro enteric test was considered according to standard. The re...

Circumstance Elaboration Joint Joint Example Elaboration Elaboration Condition Circumstance

Researchers in discourse have long hypothesized that the nuclei of a rhetorical structure tree provide a good summary of the text for which that tree was built. In this paper, I discuss a psy-cholinguistic experiment that validates this hypothesis , but that also shows that the distinction between nuclei and satellites is not suucient if we want to build summaries of very high quality. I empiri...

Effect of Coating Materials on Wear in Internal Gears

Theoretical and experimental investigation of wear during coupling in internal gears coated with various polymeric coating materials was performed in this study. In the theoretical part of the study, Archards’ wear formulation was adapted to internal gears and wear behavior in various conditions was determined. Moreover, a fatigue and wear testing apparatus having similar working principle with...

Processing and Characterization of Coating and Thin Film Materials

Coatings and thin film materials are employed in many different industrial fields for decades, mainly for protective purposes. This large experience provokes that, currently, a wide variety of technologies for both preparation and characterization are available. Particularly, focusing on energy and environmental applications, three main film types can be distinguished: (1) materials with cataly...
