翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Permeability (foundry sand) ： ウィキペディア英語版 Permeability (foundry sand) Permeability is a property of foundry sand with respect to how well the sand can vent, ''i.e.'' how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases. The permeability is commonly tested to see if it is correct for the casting conditions. ==Affecting factors== The grain size, shape and distribution of the foundry sand, the type and quantity of bonding materials, the density to which the sand is rammed, and the percentage of moisture used for tempering the sand are important factors in regulating the degree of permeability.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Permeability (foundry sand)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
