标准摘要
[中文适用范围]: ISO 27831-1:2008 第一部分规定了铁及其合金表面在任何制造、储存或服役阶段去除任何无关或 unwanted 沉积物或其他材料的清洗过程,以及为后续处理准备这些表面的过程。它不涵盖与清除服役期间积累的厚重油污或污垢的初步清洗操作、焊接准备或电气接触点的清洗相关的操作。然而,本部分中的许多过程可由用户酌情用于这些操作。本部分涵盖准备金属表面以应用以下表面涂层的所需过程:电镀金属涂层;自催化金属涂层(自催化和置换型);转化涂层;热浸涂层;喷涂金属涂层;扩散涂层;玻璃搪瓷涂层;气相沉积铝和镉涂层;粉末涂层。本部分描述了执行以下处理的过程:除油;除鳞;酸洗;除锈;化学抛光;电化学抛光。本部分将上述过程与以下金属联系起来:非耐蚀钢、铸铁和纯铁;耐蚀钢和耐热钢。 [外文原描述]: ISO 27831-1:2008 specifies processes for the cleaning of the surfaces of ferrous metals and their alloys to remove any irrelevant or unwanted deposits or other material at any stage of manufacture, storage or service and for the preparation of these surfaces for further treatment. It does not cover cleaning operations associated with the preliminary removal of heavy deposits of oil, grease or dirt accumulated during operational service, preparations for welding or the cleaning of electrical contacts. However, many of the processes included in this part of ISO 27831 may be used for these operations at the discretion of the users of this part of ISO 27831. It covers processes which are needed for the preparation of metal surfaces prior to the application of the following surface coatings: electrodeposited metal coatings; autocatalytic metal coatings (autocatalytic and displacement types); conversion coatings; hot-dipped coatings; sprayed metal coatings; diffusion coatings; coatings produced by vitreous enamelling; coatings produced by physical vapour deposition of aluminium and cadmium; powder coatings. It describes processes for carrying out the following treatments: degreasing; descaling; pickling; de-rusting; chemical smoothing; electropolishing. It relates the processes described above to the following metals: non-corrosion-resisting steels, cast irons and pure irons; corrosion-resisting and heat-resisting steels.
