This study was undertaken to provide more insight on the optimum injection temperature used for production of PE crates, thereby saving time and money, improving part quality. The work included processing trails HDPE crates in an injectionmolding machine at five temperatures ranged from 220 300°C. Both Rheological mechanical characterization conducted order understand effect properties crates. ...

Abstract Rheological properties of concrete are considered to be the most ideal method characterize working performance concrete. models used quantitatively based on yield stress and viscosity fresh cement paste. In this paper, Rheology QC was study influence different main link densities (acid-ether ratios) rheological The Bingham model fit curve slurry, stress, plastic viscosity, thixotropic ...

Each film coating formulation and film forming polymer has an individual limiting maximum viscosity value for processability which depends on the type of nozzle and coater used, as well as on the batch size. In order to optimize efficiency and quality, knowledge of the formulation dependant viscosity curves is absolutely necessary. Fig. 1: Thermo Scientific HAAKE RotoVisco 1 rotational rheomete...

In this study, chitosan (CS) grafted by glycidyltrimethylammonium chloride (GTMAC) to form GTMAC-CS was synthesized, chemically identified, and rheologically characterized. The Maxwell Model can be applied to closely simulate the dynamic rheological performance of the chitosan and the GTMAC-CS solutions, revealing a single relaxation time pertains to both systems. The crossover point of G' and ...
