文中介绍,根据上海地区的气候条件,喷雾水溶液的成分分为夏季与冬季用的二种,其配方为,第一种(每年4—9月份使用):亚硝酸钠8—10％;三乙醇胺0.5—0.6％;水——余量;第二种(每年10月到次年3月份使用):亚硝酸钠6—8％;碳酸钠0.5—0.6％;水——余量。该厂自采用亚硝酸钠水溶液喷雾防銹以来,结过九个月的考验,基本上满足了工序间防銹的要求。其特点是方法简单,成本低,可在室温下使用,不需加热,使用方便又安全,防銹效果好。
According to the article, according to the climatic conditions in Shanghai, the composition of spray water solution is divided into summer and winter with two kinds, the formula is, the first (from April to September each year): sodium nitrite 8-10%; triethanolamine 0.5-0.6%; water - balance; the second (from October to March each year): 6-8% sodium nitrite; 0.5-0.6% sodium carbonate; water - balance. The plant since the use of sodium nitrite aqueous spray rust, the test over nine months, basically to meet the requirements of anti-rust process. The utility model is characterized in that the method is simple, the cost is low, and can be used at room temperature, without heating, convenient and safe to use, and has good anti-rust effect.
