我厂防锈试验室的工人同志,配制了一种快速除锈溶液,所用的化学药品只有三种,容易买到,价钱便宜,配制方法简单,去锈能力和渗透性强,能加快机床除锈的速度。经分析比较,pH值为7～8,对机床油漆无腐蚀作用,保持油漆本色,无怪气味,对工人皮肤无刺激,受到广大职工的欢迎。现将每100公斤70～80℃的水,加入原料的配方介绍如下:664洗涤剂2公斤;碳酸钠0.1公斤;亚硝酸钠1公斤。依次放入,充分搅拌即成。每103公斤除锈溶液,可以脱洗35台左右机 I plant rust-proof laboratory laborer comrades, formulated a rapid rust solution, the use of only three kinds of chemicals, easy to buy, cheap, simple preparation method, rust resistance and permeability, can speed up the machine addition Rust speed. The analysis and comparison, the pH value of 7 to 8, no corrosion of the machine paint to maintain the true color of paint, no strange odor, no irritation to the workers skin, welcomed by the majority of workers. Now for every 100 kg of 70 ~ 80 ℃ water, add the ingredients of the formula are as follows: 664 detergent 2 kg; sodium carbonate 0.1 kg; sodium nitrite 1 kg. Followed by, fully stirred Serve. Each 103 kilograms of rust solution, about 35 units can be washed off
