GRANULAR MATERIAL, THREE-DIMENSIONAL LAMINATION-SHAPED MOLD MANUFACTURING APPARATUS, AND THREE-DIMENSIONAL LAMINATION-SHAPED MOLD MANUFACTURING METHOD |
| 摘要 |
In order to generate no harmful gas during pouring and reduce a gas defect as one cast metal defect in the manufacture of a three-dimensional lamination-shaped mold, this invention provides a granular material for use in shaping a three-dimensional lamination mold, the granular material being coated with water glass which is activated and cured by a water-soluble ester. The residual water content in the granular material is 1% or less. The water glass is one of a sodium silicate solution, a potassium silicate solution, as alkali metal silicate solutions and a mixture thereof. |
