Water soluble foundry binders with heat dehydratation hardening
Šebesta, Pavel ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
Environmental pressure on foundries has forced manufacturers to develop new organic and inorganic binders. One of the options is water soluble binders that can be hardened by dehydration. In addition to tenacity characteristics and regenerability of the forming mixtures another considered aspect is the amount of emissions generated by casting. Use of these new binders does not require expensive modifications of the machines for work with the forming mixtures.

Modern anorganic foundry binder systems
Lorenc, Michal ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
Today, the problem caused by various kinds of activities is a great impact on the environment. This also applies for the foundry industry, which has a relatively large share of this pollution. For this reason, constantly evolving new binders, which do not have such an impact on the environment. The aim of this work is to become familiar with these types of binders that are more friendly to our already devastated the planet.

Comparison of environmental and technological properties of various methods of manufacture of foundry moulds and cores
Dlouhá, Monika ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
The roots of foundry manufacture perhaps go back to 2000 BC. Since foundry production in its development has undergone four stages and each of them there was a qualitative jump. From 20 century, the chemicals used in foundry moulds and cores which is the cause producing harmful substances that have a negative impact on the environment. Major sources of harmful substances are just binders, hardeners and catalysts that are needed for bonding of moulding mixture. The third stage deals with the foundry physical processes that are not using today, even though they are most ecological. Nowadays the most used methods Cold-box, Warm-box and Hot-box.
