Embodiment Construction
[0006] The present invention will be further described below in conjunction with specific examples.
[0007] 1. Take multiple carbon head polycrystalline materials.
[0008] 2. Place it in nitric acid with a concentration of more than 80% for 8 hours; if the concentration of nitric acid is low, prolong the soaking time, otherwise, reduce the time.
[0009] 3. Take out the raw materials, and rinse off the acid and graphite powder on the surface with clean water.

The invention relates to a method for cleaning a carbon head polycrystalline material. The method comprises that: after the carbon head polycrystalline material is soaked into over 80 percent nitric acid, the soaked material is flushed by using water. The lump graphite on the carbon head polycrystalline material can be changed into powdery graphite by using the method, the powdery graphite can naturally drop from the polycrystalline material, and the polycrystalline material does not produce loss due to striking, so the method can improve the utilization rate and the income.
Description
technical field [0001] The invention relates to a method for cleaning carbon head polycrystalline material. Background technique [0002] At present, for carbon-head polycrystalline materials, manual processing is now used, that is, graphite is removed by beating, and this method will cause about 5% material loss. Contents of the invention [0003] The purpose of the present invention is to provide a method for cleaning carbon head polycrystalline material without material loss. [0004] The technical solution adopted by the present invention is: a cleaning method for carbon-head polycrystalline material, which is characterized in that the carbon-head polycrystalline material is soaked in nitric acid with a concentration above 80%, and then rinsed with water. [0005] By adopting the present invention, the massive graphite on the polycrystalline material of the carbon head can be changed into dusty graphite, which falls off naturally from the polycrystalline material with...
