清洗是各种金属在精饰前必须进行的工作,其方法很多,但以碱基清洗最为重要,本文详细讨论了碱基清洗中各成分的作用及基本配方。为降低能耗,提高清洗效果,低温清洗在金属清洗行业已得到最大的重视。与高温清洗相比,不仅耗能低,而且清洗速度快,效果好,对各种污物的敏感性极低,因此最佳的低温清洗剂只要使用合理,几乎可做到无限期使用。此外,本文还对低温清洗槽液的维护作了叙述。 Cleaning is a variety of metals must be carried out in the pre-finishing work, there are many ways, but the most important base cleaning, this paper discussed in detail the role of base cleaning and the basic ingredients of the formula. In order to reduce energy consumption, improve the cleaning effect, low temperature cleaning in the metal cleaning industry has received the greatest attention. Compared with high temperature cleaning, not only low energy consumption, but also cleaning speed, good effect, very low sensitivity to various contaminants, so the best low temperature cleaning agent as long as the use of reasonable, almost indefinite use. In addition, this article also describes the maintenance of cryogenic cleaning bath.
