The study of binder systems for technology Warm box
Lenghardová, Romana ; Malec, Silvestr (referee) ; Rusín, Karel (advisor)
The project elaborated in frame of engineering studies branch M2332-00. The project is submitting the study of binder systems for technology Warm box. Pursuant to the literary pursuit a problem of the technology Warm box these binders was tested: binder systems based of the Na-silicates, biogenous binders – proteins, polysacharides and fenol resins. Fenol resins and biogenous binders (K2 and Hide glue) showed to be optimal for core making technology Warm box. Biogenous binders are ecologically unexceptionable.

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.
