BC-411除锈剂是由北京化工研究院最近研究成功的,它是由磷酸、水和缓蚀剂按一定比例和一定过程配制而成,具有除锈、除垢、清洁、磷化、保护五种功能。我们从1981年6月开始进行有关的应用试验,并逐渐应用于注水管道内外除锈、钢模除锈、机加工件除锈、修旧利废除锈、除污、汽车水箱除垢等生产上。现把使用情况介绍如下:一、特点我们在试验和应用实践中体会到 BC-411除锈剂具有以下特点:1.适用于各种型钢、钢板、钢管及其制品、加工件的除锈。除锈速度快。2.除锈彻底,能露出金属光泽,对轮廓复杂的机加工件、小口径管子等内壁人工难于
BC-411 derusting agent is successfully researched recently by the Beijing Institute of Chemical Technology. It is prepared by mixing phosphoric acid, water and corrosion inhibitor according to a certain proportion and certain process, and has the functions of descaling, descaling, cleaning, phosphating and protection Kind of function We started from June 1981 on the application of the test, and gradually applied inside and outside the water pipe rust, steel rust, machining parts rust, the old Lee waste rust, decontamination, car water tank descaling production . Now the use of the introduction are as follows: First, the characteristics of our experience in the test and application experience BC-411 derusting agent has the following characteristics: 1. Suitable for all kinds of steel, steel, steel and its products, processing parts of the rust. Rust faster. 2. Rust thoroughly, to reveal the metallic luster, the machining of complex parts, small-diameter pipes and other artificial walls difficult
