Inorganic foundry binder systems and their uses |
摘要 |
This invention relates to inorganic no-bake foundry binder systems and their uses. The binder systems comprise as separate components: (A) mono-aluminum phosphate in an aqueous solution containing specified phosphoric acids, and (B) magnesium oxide; and certain specified zinc compounds in either the Component A, Component B or both. The components of the binder system react when they are mixed with a foundry aggregate to prepare foundry mixes which are used to prepare foundry molds and cores. The foundry molds and cores are used to cast metals. |
