The degradation of different polyethylenes, LDPE, LLDPE, and HDPE, with and without antioxidants and at different oxygen concentrations in the polymer granulates have been studied in extrusion coating processing. The degradation was followed by On Line Rheometry, Size Exclusion Chromatography, Surface Oxidation Index measurements, and GC-MS Chromatography. The degradations starts in the extrude...

The application of twin screw extrusion (TSE) as a scalable and green process for the manufacture of cocrystals was investigated. Four model cocrystal forming systems, Caffeine-Oxalic acid, Nicotinamide-trans cinnamic acid, Carbamazepine-Saccharin, and Theophylline-Citric acid, were selected for the study. The parameters of the extrusion process that influenced cocrystal formation were examined...

In this study, the effect of extrusion process parameters of a locally developed extruder on the moisture loss of extrudates of the flour and starch of maize and cassava which are grown in Nigeria in large quantity were characterized. These were compared with those of wheat flour which is commonly used for the production of alimentary paste. The parameters considered include feed moisture (30, ...

3D printers are the most common and popular method of additive manufacturing technology provide fusion materials using thermal effects. This phenomenon makes that temperature important factor affecting printing quality. The is provided by Aluminium Extruder Heat Block in extruder regime must be constant according to type material. objective this study make aluminium designs with high efficiency...
