在机加工和机械设备、汽车等的维护与修理时，大多采用柴油、煤油或汽油作清洗液来清洗零件。这不仅浪费能源，且存在着潜在的不安全因素，稍有不慎，则可能酿成火灾。近年来，一种新型的金属清洗剂逐渐得到了广泛的应用，它能够很好地替代柴油、煤油和汽油来清洗零件，而且价格便宜，使用安全，很适合于机械化清洗作业。它可以为金属洗涤，而不会有锈斑，这就是所谓的金属清洗剂

金属清洗剂的分类:

1、酸性化学清洗剂;

2、碱性化学清洗剂;

3、水基型清洗剂;

4、半水基型清洗剂;

5、溶剂型金属清洗剂。

In the maintenance and repair of machining and mechanical equipment, automobiles, etc., diesel, kerosene or gasoline are mostly used as cleaning fluids to clean parts. This is not only a waste of energy, but also there are potential unsafe factors. If you are careless, it may lead to fire. In recent years, a new type of metal cleaning agent has gradually been widely used. It can be a good alternative to diesel, kerosene and gasoline to clean parts, and it is cheap, safe to use, and suitable for mechanized cleaning operations. It can be washed for metal without rust spots. This is called metal cleaning agent
Classification of metal cleaning agents:
1, acidic chemical cleaning agent;
2, alkaline chemical cleaning agent;
3, water-based cleaning agent;
4, half water based cleaning agent;
5, solvent type metal cleaning agent.
