In addition to the commonly used caustic wash accident, the same molybdenum cleaning method as other metals is also used by pickling. Xiaobian here to recommend a program: 50% by volume of nitric acid plus 10% by volume of hydrofluoric acid mixed acid cleaning The temperature of the cleaning process must be controlled between 102 and 150 degrees Fahrenheit. This mixed pickling not only effectively removes oxides from the molybdenum product, but also removes the copper left over from the EDM process step by step. Pickling After the molybdenum product must be washed repeatedly in clean water.
Since this mixed acid is a high-risk item, all washing steps should be subject to strict protective measures. Suitable safety equipment for the cleaning of molybdenum products include masks, acid-resistant gloves, chemically resistant aprons and boots, and very good ventilation.
