Paperback. Zustand: New. Print on Demand. This book presents the second volume of Ralph Grim's extensive research on bonding clays employing fundamental and practical scientific techniques. His study of dry molding sands and green molding sands provides a critical examination of what occurs at a molecular level when silicate cla…ys interact with tempering water. The author plots the properties of various clay types in graphs and charts, allowing readers to visualize the exact correlation between the amount of silicate clay content in a sand, the amount of tempering water used, and its effect on the resulting dry and green compression strengths. Temperature, drying time, and other factors are also considered, allowing the reader to determine crucial information about the outcome of their mold before casting. This volume is essential reading for geologists, chemists, and materials scientists involved in metallurgy, ceramics manufacturing, and the petroleum industry to optimize the materials and processes used. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Paperback. Zustand: New. Print on Demand. This book explores the structure, composition and properties of clays, minerals that are the primary components of clays and shales, uncovering their profound impact on the properties of molding sands. The author emphasizes the importance of understanding the precise composition of bondi…ng clays to maximize the production of better castings and more economical metal founding. Offering a fundamental classification of bonding clays based on the mineral components of clays, this book describes the green compression strength and bulk density properties that are characteristic of each class. It presents a theory of the bonding action of clays in molding sands and an explanation of the variation of bulk density in molding sands. This book reveals how the properties of any clay are highly dependent on its clay mineral composition, thereby providing a basis for classication. The author demonstrates that one class of bonding clays, halloysite, possesses bonding value, a previously unrecognized discovery made during the course of this investigation. The author posits that the bonding action of clay is not a gluing or adhesive effect but rather the result of wedge-block formations at the junctions of the quartz grains, resulting from the rigid character of the initial adsorbed water. This theory explains the unusual air-set strength characteristics of sands bonded with kaolinite or halloysite clay, which develop greatly increased strength without an accompanying water loss when they are allowed to stand in the air after ramming. This book concludes that the insights gained from this study into the fundamental structure of clays and the cause of their properties will undoubtedly have long-lasting significance and lead to improved mold making practices, lower costs, reduced defective castings, increased production, and better castings. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
