Abstract:
(EN) The present invention provides a mold material that enables a mold, which is a final product of the mold material, to suppress adhesion of the mold material and/or a solidified product thereof to a molded article, while having excellent mold strength and excellent mold fillability. This mold material is configured to contain at least (a) a refractory aggregate, (b) a water-soluble inorganic binder and (c) a powder of an iron-containing compound; and the powder of an iron-containing compound has an average particle diameter of 0.01 μm or more but less than 50 μm.
(FR) La présente invention concerne un matériau de moule qui permet à un moule, qui est un produit final du matériau de moule, d'éliminer l'adhérence du matériau de moule et/ou d'un produit solidifié de ce dernier à un article moulé, tout en ayant une excellente résistance au moulage et une excellente aptitude au remplissage de moule. Ce matériau de moule est conçu pour contenir au moins (a) un agrégat réfractaire, (b) un liant inorganique soluble dans l'eau et (c) une poudre d'un composé contenant du fer, la poudre de composé contenant du fer ayant un diamètre moyen de particule de 0,01 µm ou plus mais inférieur à 50 µm.
(JA) 最終的に得られる鋳型において、鋳造製品に対する鋳型材料及び/又はその固化物の付着が抑止され、また、優れた鋳型強度及び鋳型充填性を発揮する鋳型材料を提供すること。 (a)耐火性骨材と、(b)水溶性無機粘結剤と、(c)鉄含有化合物の粉状物とを少なくとも含み、鉄含有化合物の粉状物として、平均粒子径が、0.01μm以上50μm未満であるものを用いて、鋳型材料を構成した。
