Water soluble foundry binders with heat hardening
Dratnal, Lukáš ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
With the increasing foundry requirements we are forced to develop new kinds of foundry binders, either organic or inorganic. There are several requirements for the molding composition and for the proper function. The sand mixture must exhibit appropriate technological, economic and also ecological characteristics. Many environmentally harmful wastes are created from the organic substances contained mainly in binders and catalysts used for molding of the mixture. A good application can be the water-soluble binder cured by heat. These binders allow easy and fast processing and a mixture recoverability.
