防锈剂(又名软水剂或清罐剂)在东北铁路上各机务段,已于一九五一年六月全部使用,关内也已大部使用。当你乘火车旅行时,会发现机车水箱或客车盥嗽室,写着水中有药,禁止饮用等字样,机车行至中途有时间断的放出一种白色气体(此种现象叫放水作业),这都说明了机车已使用了防锈剂。但有很多人不明瞭防锈剂的成分究竟是什么?防锈剂的性质和作用那一定更不明瞭。为了把这一简单的科学智识让每一个人都了解,现在把我所了解的一部分,简单择要的介绍一下,但不是完整无缺的,希望读者给以批评和改正。防锈剂是有机物质和无机物质互相混合配成,无机物质多用钠化合物,如氢氧化钠、磷酸三 Rust inhibitor (also known as water softener or cleaning agent) in the Northeast Railway locomotive depot, all used in June 1951, has also been mostly used inside. When you travel by train, you will find locomotive water tank or bus toilet room, says there is medicine in the water, the prohibition of drinking and other words, the locomotive line to the middle of the intermittent release of a white gas (this phenomenon is called water work) This shows that the locomotive has used a rust inhibitor. But many people do not understand what is the composition of anti-rust agent? The nature and role of anti-rust agent that must be more unknown. In order to make this simple scientific knowledge known to everyone, we now introduce some of what I know, simple and selective, but they are not complete, and I hope readers will criticize and correct them. Rust inhibitor is a mixture of organic and inorganic substances dubbed inorganic compounds with sodium compounds, such as sodium hydroxide, tris
