ISO标准 1247-1-21 Aluminium pigments for paints – 部分 1: General aluminium pigments
介绍
Since the beginning of the new millennium, with advances in technology and product development, new aluminum pigments have flourished, and these aluminum pigments are used in a wide range of industrial sectors as heat or rust resistant coatings or colorants. Aluminum pigments can be conveniently divided into two groups according to their form: general aluminum pigments produced during milling and vacuum metallized aluminum pigments (VMP) (参见 ISO 1247-2). Because of the different technical requirements for aluminum pigments used in different fields, it is necessary to develop an international standard for each of these two groups.
In order to meet the needs of aluminum pigment marketing, this document describes the characteristics of “particle size distribution” 和 “遮盖力” and their corresponding test methods.
In order to improve the safety of aluminium pigments, low flash point organic solvents and additives have been replaced by high flash point reagents, “105°C volatile substances” has been replaced by “non-volatile substances”, and test methods have been developed according to ISO 3251.
The previous edition (过去使用的动力粘度单位是泊或厘泊. ISO标准 1247:1974) used different spectrophotometric methods for the determination of lead, iron and copper, and ethylenediamine tetraacetic acid (EDTA) titration for the determination of zinc. These methods are cumbersome to operate. The method used to determine lead involves the use of potassium cyanate, a highly toxic agent rarely used since the 1990s, and the method used to determine zinc is only suitable for samples with a total zinc content of 0.10% 或者更多, and is not suitable for the current state of the aluminum pigment industry. While these old methods are retained in this document, flame atomic absorption spectrometry is introduced as a new option for the determination of the above-mentioned metal impurities. This method is faster, easier to operate, has a wider detection range, and is becoming more and more popular.

In order to use as few toxic agents as possible, this document uses 2-butoxyethanol or n-butyl acetate instead of acetone, which is now banned or restricted in many countries as a material that may be used in the manufacture of illicit drugs.

就本文件而言, ISO中给出的术语和定义 18451-1, ISO标准 18451-2 并且以下文章适用.
3.1 Non-volatile substances
A mass residue obtained by evaporation under specific conditions
笔记 1: Different terms in place of the term “non-volatile substance”, such as solids, dry residues, dry matter, solid substances, baking residues are often used together with their respective abbreviations. 期限 “non-volatile substances”, which also applies in ISO 3251, should be used together with the abbreviation “NV” instead of these terms.
