在涂漆及相关产品前钢材基底的处理 非金属喷砂磨料规范 第11部分：火山岩

[中文适用范围]： 本文件规定了火山岩熔岩作为喷射清理工艺中使用的磨料的要求。它指定了颗粒尺寸的范围和表观密度、莫氏硬度、含水量、水提取物的电导率以及可溶性氯化物的质量分数值。本文件规定的这些要求仅适用于全新状态提供的磨料。它们不适用于磨料在使用期间或使用后的任何阶段。 尽管本文件是专门为满足准备钢结构表面的要求而制定的，但所规定性质通常也适合在使用喷射清理技术准备其他材料表面或组件时使用。这些技术在 ISO 8504-2 中进行了描述。 [外文原描述]： This document specifies requirements for volcanic lava, as supplied for blast-cleaning processes. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this document apply to abrasives supplied in “new” condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127 series . NOTE Although this document has been developed specifically to meet requirements for the preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504 - 2 .
