摘要:
The invention relates to molding material mixtures containing a molding base material, water glass, amorphous silicon dioxide and an oxidic boron compound, and the production of molds and cores, in particular for metal casting.
摘要:
The invention relates to a binder, which contains water glass and further a phosphate or a borate or both. The invention further relates to a method for constructing molds and cores layer by layer, the molds and cores comprising a construction material mixture, which at least comprises a refractory molding base material, and the binder. In order to produce the molds and cores layer by layer in 3-D printing, the refractory molding base material is applied layer by layer and is selectively printed with the binder layer by layer, and consequently a body corresponding to the molds or cores is constructed and the molds or cores are released after the unbonded construction material mixture has been removed.
摘要:
The invention relates to lithium-containing molding material mixtures comprising a refractory main molding material, an inorganic binder, and amorphous silicon dioxide as an additive in the production of molds and cores for metal casting. The invention further relates to a method for producing molds and cores using the molding material mixtures and to molds and cores produced according to the method.
摘要:
The invention relates to a method for producing casting moulds and cores, according to which a moulding material mixture consisting of at least one refractory material and water glass as an inorganic binding agent is cured with the aid of a carbonyl compound introduced into the gas phase, or carried with the gas phase. The invention also relates to a corresponding moulding material mixture, to a multi-component system and to moulds and cores produced according to the method.
摘要:
The invention relates to mold material mixtures on the basis of inorganic binders, for producing molds and cores for metal casting. Said mixtures consist of at least one refractory mold base material, an inorganic binder and amorphous silicon dioxide as an additive. The invention also relates to a method for producing molds and cores using said mold material mixtures.
摘要:
The object of the invention is a component system for producing a binder for metal casting on the basis of phenolic resins of the benzyl ether type and isocyanates containing non-polar solvents.
摘要:
The invention relates to mold material mixtures containing an oxide of aluminum and an oxide of zirconium as particulate mixed metal oxide, in combination with refractory mold base materials and a water glass-based binder system. The mold material mixtures, also in the form of multicomponent systems, are used for the production of molds and cores for the foundry industry.
摘要:
The invention relates to mold material mixtures containing at least one aluminum oxide in the alpha phase and/or at least one aluminum/silicon mixed oxide, except for aluminum/silicon mixed oxides having a layered silicate structure, as a particulate metal oxide, in combination with refractory mold base materials and a water glass-based binder system. The mold material mixtures are used for the production of molds and cores for the foundry industry.
