这网站上详细讲述了洗轴的全过程,非常好,而且极具科学性,可惜是英语的,所以不是每个朋友都能看的懂。
关于洗轴,很多人都进入了一个误区,就是洗轴用的溶剂的选择。
大多数人选择了zippo油,其实zippo油并不是最好的选择,当然可以胜任,但绝不是最好的选择。
为什么呢?洗轴的目的就是去除轴承里的污渍,所以洗轴有两个原则
1. 要用强有力的溶剂溶解污渍。
2. 溶剂本身不能携带任何杂质,更不能有强腐蚀性。
zippo油便不符合第二个条件
为了在使用中效果更好,厂家往往在油中添加部分香料,来达到更好的味道。厂家也会加入一些化学试剂,减慢油的蒸发速率。
因此,zippo油实际上载第一次清洗的时候效果明显(外部赃物太多),而接下来效果就不明显了,甚至可能倒退。
大家没有想过吗,有按理说是会全部挥发的,但是你们用zippo油洗过的轴是不是久久还有一股味道呢?
下面推荐一种我个人比较喜欢的洗轴溶剂,paint thinner,就是希那水,做过高达模型的人肯定都知道,就是渗线用的溶剂,当然zippo有也可以,因为对于高达模型渗线,少数杂物无伤大雅。
但是轴承洗轴就不一样了,要求用纯的溶剂。
这里推荐田宫(TAMIYA)的X-20 thinner, 250ml 30RMB左右,还是很划算的,当然比路边摊买的zippo油贵一点。

Testing Solvents to Determine Suitability for Bearing CleaningEdit
Some solvents are suitable for the purpose of cleaning bearings and some are not. Solvents that evaporate too quickly can leave behind debris and residue and solvents that are too harsh will attack metal and cause corrosion(rust). Not all solvents are clean and some will leave behind contaminants when they evaporate. Some solvents contain additives that enhance their usage for certain purposes. An example is lighter fluid which is primarily a solvent called naphtha which contains additives to make it smell more pleasant and to prevent rapid evaporation when used in lighters.
Some examples of suitable solvents for cleaning bearings are mineral spirits, also called paint thinner, and nearly pure isopropyl alcohol. Isopropyl alcohol is not rubbing alcohol. While rubbing alcohol does have isopropyl alcohol in it, it also has oils to enhance its use on skin as well as perfumes to make it more pleasant to smell. These additives make it a poor choice to clean a bearing because they are left behind when the alcohol evaporates.
