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.

Application of biogenous core binder for production of castings in automotive field
Vymyslický, Jakub ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
This thesis deals with foundry binders and it is narrowly focused on biogenous binders used for production of castings in automotive field. There is a short overview of all groups of forming and core mixtures at the beginning of the thesis, which describes chemical composition of the mixtures and also development history of the mixtures. The thesis continues by focusing on biogenous binders, which are developed for the automotive field and with another biogenous binders which fits with the automotive field demands. Overview of technological and ecological properties was made for all of the listed biogenous binders. Advantages and disadvantages of the biogenous binders were also noted.

Water soluble foundry binder with heat hardening
Prokop, Tomáš ; Burianová, Klára (referee) ; Cupák, Petr (advisor)
Foundry production produces the biggest amount of dangerous waste, which has a negative impact on environment and working conditions in the foundry. The foundry engineers test new technologies of shaping mixtures with new binders to protect environment and working conditions. We can reduce the production of dangerous waste by using better technologies and less harmful materials, which are needed for modeling forms and cores. The large source of pollution are binders, hardeners and catalyzer needed for binding sand. This work is focused on new types of ecological binders, which are dissolvable in water and are formed by setting temperature. These binders are ecological variants of known inorganic and organic binders.
