Ultrasonic Extrusion Excerpt :

Earlier work on the ultrasonic extrusion of lead and aluminum has been extended to the cold extrusion of plasticized ceramic compositions, resulting in significant improvements in increased extrusion rate (more than 100-fold), decreased extrusion pressure (2 to 10 fold), and in extruded specimen properties. It has also been found possible to extrude materials which are normally nonextrudable because of their low plasticizer or water content. Fused, ground alumina could be ultrasonically extruded with 15% less water than the minimum content without ultrasonics, and only 40 to 60% of that used in normal commercial practice. Significant improvement in the strength of as-extruded shapes, as well as reduced shrinkage and deformation in drying and firing, resulted. Compositions normally using 3 w/o ammonium alginate as a plasticizer can be extruded with 0.2 w/o plastizer when ultrasonically activated. It has been postulated that the ultrasonic effects observed are derived from reduction of surface friction, shear thinning of the thixotropic systems, particle orientation, surface-film rupture, and wetting phenomena. As-extruded specimen improvement was evidenced by a smoother surface and freedom from cracks, tearing, and peeling. When steel dies were used, abrasion of the die surface sometimes caused a superficially discolored surface in nonultrasonic extrusions. The comparable ultrasonic extrusions showed little or no discoloration as the ultrasonic power level was increased. Ultrasonically extruded specimens which were fired in the same kiln loading as their corresponding controls show small but consistent increases in fired density. Water absorption was approximately 75% of the control. The highest moduli of rupture in the fired specimens were found in the ultrasonic specimens even though these required only 25% of the extrusion pressure of the controls.

Extrusion Processing Technology Excerpt :

Extrusion is the operation of forming and shaping a molten or dough-like material by forcing it through a restriction, or die. It is applied and used in many batch and continuous processes. However, extrusion processing technology relies more on continuous process operations which use screw extruders to handle many process functions such as the transport and compression of particulate components, melting of polymers, mixing of viscous media, heat processing of polymeric and biopolymeric materials, product texturization and shaping, defibering and chemical impregnation of fibrous materials, reactive extrusion, and fractionation of solid-liquid systems. Extrusion processing technology is highly complex, and in-depth descriptions and discussions are required in order to provide a complete understanding and analysis of this area: this book aims to provide readers with these analyses and discussions. Extrusion Processing Technology: Food and Non-Food Biomaterials provides an overview of extrusion processing technology and its established and emerging industrial applications. Potency of process intensification and sustainable processing is also discussed and illustrated. The book aims to span the gap between the principles of extrusion science and the practical knowledge of operational engineers and technicians. The authors bring their research and industrial experience in extrusion processing technology to provide a comprehensive, technical yet readable volume that will appeal to readers from both academic and practical backgrounds. This book is primarily aimed at scientists and engineers engaged in industry, research, and teaching activities related to the extrusion processing of foods (especially cereals, snacks, textured and fibrated proteins, functional ingredients, and instant powders), feeds (especially aquafeeds and petfoods), bioplastics and plastics, biosourced chemicals, paper pulp, and biofuels. It will also be of interest to students of food science, food eng

Extruding Plastics Excerpt :

Worldwide, extrusion lines successfully process more plastics into prod ucts than other processes by consuming at least 36 wt% of all plastics. They continue to find practical solutions for new products and/ or prob lems to meet new product performances. This book, with its practical industry reviews, is a unique handbook (the first of its kind) that covers over a thousand of the potential combina tions of basic variables or problems with solutions that can occur from up-stream to down-stream equipment. Guidelines are provided for maxi mizing processing efficiency and operating at the lowest possible cost. It has been prepared with an awareness that its usefulness will depend greatly upon its simplicity and provision of essential information. It should be useful to: 0) those already extruding and desiring to obtain additional information for their line and/ or prOVide a means of reviewing other lines that can provide their line with operating improvements; (2) those processing or extruding plastics for the first time; (3) those consider ing going into another extrusion process; (4) those desiring additional information about employing the design of various products more effi ciently, with respect to both performance and cost; (5) those contemplat ing entering the business of extrusion; (6) those in new venture groups, materials development, and/ or market development; (7) those in disci plines such as nonplastics manufacturers, engineers, designers, quality control, financial, and management; and (8) those requiring a textbook on extrusion in trade schools and high schools or colleges.

The Influence of Processing Variables on the Structure and Properties of Extruded Beta III Titanium Excerpt :

The extrusion temperature and cooling rate after extrusion were varied for round to round axisymmetric extrusions of the Beta 111 titanium alloy. The microstructures after extrusion and after heat treatment were examined both by optical and transmission electron microscopy and correlated with the room temperature mechanical properties. Heat treatment following extrusion consisted of either aging only or a solution treatment followed by aging. In contrast to air cooling after extrusion, direct water quenching immediately after extrusion was effective in retaining a significant amount of dislocation structure from the hot deformation, the effect being greater at the lowest extrusion temperature. This retained dislocation structure effectively promoted the formation of alpha during aging and retarded the tendency for the omega phase to form. The effect was greatest when specimens were aged without the intermediate solution treatment. The greater amount and finer distribution of alpha obtained in this manner resulted in significantly higher tensile strengths, quite acceptable values of RA, but with a small loss in fracture toughness. For the extrusion temperature range investigated, the extrusion pressures for the Beta 111 titanium alloy were somewhat lower than for the older, more well established beta titanium alloy. he extrusion pressures for Beta 111 were also lower than for alpha and alpha plus beta titanium alloys, for temperature ranges where they have significant amounts of alpha present.
