Standard Specification for Synthetic Brown Iron Oxide Pigment 合成棕氧化铁颜料的标准规范
发布日期: 2019-10-01
1.1 本规范涵盖了商业上称为合成纯棕色氧化铁及其混合物的颜料。这些颜料适用于油漆和涂料。制造方法包括: 1.1.1 铁盐沉淀。 1.1.2 沉淀氧化铁的煅烧。 1.1.3 合成红色、黄色和黑色氧化铁的混合物。 1.1.4 合成红色、黄色和黑色氧化铁的混合物加上炭黑的添加,最大添加量为5.0 %. 添加少量炭黑以获得合成棕色氧化铁或炭黑单独使用时无法获得的着色。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
1.1 This specification covers the pigments commercially known as synthetic pure brown iron oxides and blends. These pigments are suitable for use in paints and coatings. Methods of manufacture are: 1.1.1 Precipitation of iron salts. 1.1.2 Calcination of precipitated iron oxides. 1.1.3 Blends of synthetic red, yellow, and black iron oxides. 1.1.4 Blends of synthetic red, yellow, and black iron oxides plus the addition of carbon black to a maximum of 5.0 %. Small amounts of carbon black are added to obtain tinting colors not obtainable when synthetic brown iron oxide or carbon black are used singly. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
