| Described herein, in a preferred embodiment, is a leonardite-based polyurethane resin binder that may be used, among other applications, as a binder in combination with foundry aggregate, e.g., sand, for molding or casting metal parts. The binders described herein comprise a humic substance, preferably leonardite, first mixed with a foundry aggregate and then the humic-aggregate mixture is combined with a polymerizable polyol, an isocyanate, and a polymerization catalyst to make a polyurethane resin binder in situ in a foundry aggregate, such as sand. The lignite is added as a solid to the foundry aggregate, and improves the binder performance of the lignite-containing part of the binder components. | ||||||

| A method for producing a moulding sand that is in particular recirculated, for foundry purposes. According to the invention, a mixture of a granular substance and aggregates, such as a binding agent and water, are added to a material that is not capable of swelling in water. The latter material comprises cavities with a specific surface area of more than 10 m2/g, in particular more than 50 m2/g and preferably more than 100 m2/g, for improving the characteristics of the moulding sand and/or for reducing the emission of harmful and/or odorous substances. | ||||||
| 11 | Method of casting a reactive metal against a surface formed from an improved slurry containing yttria | US523120 | 1990-05-14 | US5221336A | 1993-06-22 | Robert A. Horton |
| Reactive metals, such as titanium or nickel-chrome superalloys containing rare earths, are cast with mold and/or core surface areas formed from an improved slurry. The improved slurry contains yttria to form an inert surface which is exposed to the molten reactive metal. In order to prevent premature gelation of the slurry, the forming of defects in the mold and/or core surface areas, and the forming of defects in the cast article, the slurry contains a source of hydroxyl ions. The source of hydroxyl ions is sufficient to result in the slurry having a pH of at least 10.2 six days after initially mixing the slurry. The source of hydroxyl ions may be a metal alkali or an organic hydroxide. It is believed that the source of hydroxyl ions functions as a hydration suppressant for the yttria to prevent premature gelation of the slurry. The slurry contains a silicon oxide (SiO.sub.2) to alkali ratio which is equivalent to a silicon oxide to sodium oxide (Na.sub.2 O) dry weight ratio of less than thirty-to-one (30:1). | ||||||

| PURPOSE: To improve the productivity of a core and to reduce the production cost by forming binder impregnating layer and slurry coating layer on a core raw body combining aggregate and inorganic binder and further coating paraffin wax layer on the outer surface. CONSTITUTION: The core raw body 10 is formed by the aggregate kneading silica sand, silica flower, etc., as the main raw material for the core and the inorganic binder, and the binder impregnating layer 12 is formed by dipping in the binder. Next, the slurry containing ethyl silicate, etc., is applied on the surface of impregnating layer 12 by spraying method, etc., to form the coating layer 14. Further, after drying, the paraffin wax layer 16 is formed on the core raw body 10 by the dipping, etc. Next, the core 10A is fixed in the metallic pattern 18 to form expendable pattern 20. The binder impregnating layer 12 improves the strength of core, and so individual firing and sintering processes are unnecessary. Therefore, the productivity of core is improved and the production cost is reduced. COPYRIGHT: (C)1988,JPO&Japio | ||||||
