Inorganic binders (eBook, ePUB)

for mould and core production in the foundry

• Format: ePub

Produktbeschreibung

In addition to clay minerals, which have been used for decades as a binder for the compaction moulding process (with bentonite moulding materials), there are also inorganic chemically curing binder systems od long-standing tradition in the foundry. Since the forties of the last century cement has has been used for mould and core production. The core production was then revolutionized in the fifties by the water glass CO2 process. Since the Fifties, theclassical inorganic systems have superseded the organic binder systems, with notable increase around the 1970s and 80s. Due to a constantly increasing environmental awareness in the foundry industry, which has been increasingly underpinned by government calls for an improvement in casting production, the almost forgotten inorganic binder systems had a renaissance at the turn of the century. There is some misleading and even conflicting information surrounding the current state of the application, as well as its achievable property level. Therefore, this book should be attempted as complete as possible. It is aiming to provide answers to the question of what can afford inorganic binder systems at the present. On the other hand this book should open questions or problems to be solved for a further increasing of proportions in mould and core production in the coming years.

Autorenporträt

Dr. Eng. habil. Hartmut Polzin is working on the Foundry Institute of TU Bergakademie Freiberg. His research focuses among others on the area of inorganic binder systems. After studying foundryment in Freiberg he received his doctorate in 1999 with a dissertation on microwave hardening of water-glass bonded foundry moulding materials to Dr. Eng. After several years working in a foundry, he returned to the Foundry Institute and is responsible for teaching and research in the field of moulding materials and moulding processes since 2008.
