国际标准化组织 8504-3-2018 “使用油漆和相关产品之前钢基材的准备 – 表面处理方法 – 部分 3: 用手和电动工具清洁”

介绍
The protective coating properties of paint and related products applied to steel are significantly affected by the surface state of the steel before coating. The main factors known to affect this performance include:

A) There is corrosion and mill scale;

乙) 表面污染物的存在, 包括盐, 灰尘, 油和油脂;

C) 表面轮廓.

国际标准化组织 8501 和ISO 8502 准备好提供评估这些因素的方法, 而ISO 8504 提供可用于清洁钢基材的制备方法的指导, indicating the ability of each method to achieve a specified level of cleanliness.

These international standards do not contain recommendations for protective coating systems applied to steel surfaces. 它们也不包含针对特定情况的表面质量要求的建议, 尽管表面质量可以直接影响要应用的保护涂层的选择及其性能. These recommendations are found in other documents such as national standards and codes of practice. Users of these international standards should ensure that the specified quality is:

– Compatible with and applicable to the environmental conditions to which the steel will be exposed and the protective coating system to be used;

– 在规定的清洁程序的能力范围内.

国际标准化组织 8504-3-2018 “使用油漆和相关产品之前钢基材的准备 – 表面处理方法 – 部分 3: 用手和电动工具清洁”

The above three international standards cover the following aspects of steel substrate preparation:

国际标准化组织 8501 (所有部分) : 表面清洁度的目视评估;

国际标准化组织 8502 (所有部分) : 表面清洁度评估测试;

国际标准化组织 8504 (所有部分) : 表面处理方法.

这些国际标准中的每一个都分为不同的部分.

The main objective of surface treatment is to ensure the removal of harmful substances and to obtain a surface that allows a satisfactory adhesion of the primer to the steel. It also helps to reduce the amount of contaminants that cause corrosion.

This document describes how to clean manual and power tools. It should be read in conjunction with ISO 8504-1.

Manual and power tool cleaning are surface treatment methods that typically provide a lower surface cleanliness than that achieved by sandblasting. When results similar to sandblasting cleaning are required, these methods in most cases require the use of multiple types of power tools, which makes surface treatment complicated and expensive. It is often impossible to remove oils, greases and corrosion irritants such as chlorides and sulfates.

Power tool cleaning generally provides a better base for the primer than hand tool cleaning, resulting in better paint performance.

Both manual and power tool cleaning are suitable surface treatments. Hand tool cleaning in particular requires the use of primers with good surface wetting ability. Power tool cleaning is appropriate when a higher quality grade of surface treatment is required, sandblasting cleaning is not allowed or the interested parties consider it not feasible.

Representative photographic examples of St 2, St 3, PSt 2, PSt 3 and PMa (参见 ISO 8501-1 和ISO 8501-2) for evaluating some new and previously coated steel surfaces cleaned using hand or power tools. Since many different situations arise during surface preparation and these photographs are not always sufficient to describe specific examples, it is recommended that special photographs of the treated reference area acceptable to all parties concerned be made as the basis for further surface preparation procedures.

1 范围
This document describes how to clean the steel substrate with hand tools and power tools before applying paint and related products. It is suitable for both new steel structures and previously coated steel surfaces that show areas of decomposition where paint needs to be maintained. It describes the equipment to be used and the procedures to be followed.

3 术语和定义
就本文件而言, 以下术语和定义适用.

国际标准化组织 8504-3-2018 “使用油漆和相关产品之前钢基材的准备 – 表面处理方法 – 部分 3: 用手和电动工具清洁”

3.1 Cleaning Hand Tools

A method of preparing steel substrates using hand tools without power assistance

笔记 1: Chipping hammer, hand scraper, hand line brush, sandpaper and plastic wool embedded with abrasive are usually used. Sometimes hand tool cleaning is done initially to remove relatively loose contaminants before using power tools.

3.2 Clean power tools

A method for preparing a steel substrate using a power-assisted hand tool, but excluding shot blasting cleaning

笔记 1: Rotary scaler, rotary wire brush, rotary impact tool, sander, sander, rotary abrasive coated paper wheel (turning wheel), abrasive grinder, plastic wool with embedded abrasive, chipping hammer and needle gun, driven by electric or pneumatic, or connected to remote control or robotic equipment, are examples of equipment commonly used.

3.3 水, solvent or chemical cleaning

Method for removing visible oil, grease, dirt or process lubricants and other soluble contaminants from steel surfaces

笔记 1: For more details and cleaning methods, 参见 ISO 12944-4:2017, 6.2.

3.4 Contaminated surface

A surface with substances that are harmful to the performance of the protective coating system

笔记 1: Typical contaminants include slag, rust, laminate rust, mill scale, 油, grease, flux and weld spatter, soluble iron corrosion products, and other soluble salts, including chlorides and sulfates.

3.5 Cleaning Surfaces

A surface where contaminants have been removed to a specified or agreed surface cleanliness level

笔记 1: Complete details are provided in ISO 8501-1 和ISO 8501-2.
