机床和设备上的油漆应颜色调和、光滑明亮,一般以浅灰色或浅绿色为宜。但时间一长,油漆表面因润滑油、切削液等的化学作用而变色,俗称“黄袍”。过去我厂用热碱水和煤油进行清洗,这些方法不但对人的皮肤有害,浪费煤油.而且效果不佳。我们经反复试验,采用下列配方溶液,清洗设备“黄袍”,不但避免上述弊病,而且效果很好。溶液配方(以重量计):碳酸钠 Na_2CO_32%;磷酸三钠 Na_3PO_4·12H_2O 2%油酸 CH_3(CH_2)_7CH=CH(CH_2)_7COOH 2%
Paint on the machine and equipment should be color harmony, smooth and bright, generally light gray or light green is appropriate. But over time, the paint surface due to lubricants, cutting fluids and other chemical changes and discoloration, commonly known as “yellow robe.” In the past I used to clean the plant with hot alkali and kerosene, these methods not only harmful to human skin, kerosene waste. And the effect is not good. We have repeatedly tested the following formula solution, cleaning equipment “yellow robe”, not only to avoid the above shortcomings, and the effect is very good. Solution formulation by weight Sodium Carbonate Na_2CO_32%; Trisodium Phosphate Na_3PO_4 · 12H_2O 2% Oleic Acid CH_3 (CH_2) _7CH = CH (CH_2) _7COOH 2%
