A propos de cet article

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 bonding 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.…
