为了展示广泛分布于那波利地区的内亚波列登(Neapolitan)黄色凝灰岩即含钙十字沸石火山岩可能的工业应用前景,本文介绍了该凝灰岩技术数据的测定,指出了其钙十字沸石含量通常大于50％的凝灰岩所具有的均质性以及获得其沸石含量大于60％的具有工业意义的粒级组分的可能性。其30—50目粒级组分的重要特性是硬度大、填充床密度高、离子交换能力强。
To demonstrate the potential industrial application of Neapolitan yellow tuff, a calcareous phreatic volcanic rock widely distributed in the Napoli area, this paper presents the determination of technical data for the tuff, pointing out that its calcium phillipsite content is generally greater than The homogeneity of 50% of tuff and the possibility of obtaining industrially interesting fraction components with zeolite content greater than 60%. The important characteristics of its 30-50 mesh size components are high hardness, packed bed density, ion exchange capacity.
