Granular material, granular material manufacturing method, three-dimensional laminated and shaped mold manufacturing apparatus, and three-dimensional laminated and shaped mold manufacturing method
The present invention is a granular material that can be well recoated regardless of the type of the granular material, and enables a refractory aggregate in an unprinted portion to be used without any regeneration process, in the manufacture of a three-dimensional laminated and shaped mold. This granular material is a granular material for use in three-dimensional laminated mold shaping, and obtained by adding a material that causes a hydration reaction having a moisture absorbing function and generates a catalytic effect to a coating material mixed with or coated with an acid as a catalyst which activates and hardens an organic binder for binding the granular material.
COMPOSITIONS AND PROCESSES FOR DOWNHOLE CEMENTING OPERATIONS
The present invention relates to methods of cementing, for example, an oil or gas well. The method may involve pumping a suspension of a filler mixture and at least about 5 weight percent of a thermosetting resin based on the total weight of resin and filler mixture. Advantages may include superior properties and reliability as compared to conventional cementing operations often involving Portland cement.

METHOD FOR PREPARING COMPOSITE METAL OXIDE HOLLOW FIBRE
The invention relates to a method for preparing a composite metal oxide hollow fibre. A certain stoichiometry of composite metal oxide raw material and a polymer binding agent are added to an organic solvent, and mixed mechanically to obtain an evenly dispersed spinning solution having a suitable viscosity. After defoaming treatment, the spinning solution is extruded through a spinneret and, after undergoing a certain dry spinning process, enters an external coagulation bath; during this period, a phase inversion process occurs and composite metal oxide hollow fibre blanks are formed. The blanks are immersed in the external coagulation bath and the organic solvent is displaced; after natural drying, the blanks undergo a heat treatment process; during this period, polymer burn off, in situ reaction, and in situ sintering processes occur to obtain the composite metal oxide hollow fibre.
