由于人工除锈劳动强度大,机械除锈不仅设备复杂而且部分工厂还受厂房条件限制,因而采用化学方法除锈就成为当前的重要课题.为此,本期特介绍“涂漆前金属表面准备工作的简易方法”和“不除锈涂漆”两篇译文,作为有关方面在试验研究中的参考.同时,也希望有关同志为本刊提供这方面的研究成果,以便组织经验交流,加速完成这一研究课题. Due to the labor intensity of artificial derusting, the mechanical descaling is not only complicated in equipment but also limited by the factory conditions in some factories, and therefore chemical descaling has become an important issue nowadays.Therefore, this issue introduces “Preparation of metal surface before painting Simple method of work ”and“ non-rust paint ”as reference for the relevant parties in the experimental research.At the same time, I also hope that the relevant comrades to provide our research results in this area in order to exchange experience and accelerate the completion of This research topic.
