Polish molybdenum electrode is molybdenum electrode through polishing process. The polishing is a kind of processing method which is under mechanical, chemical or electrochemical effect, so that the surface roughness is reduced to obtain bright, smooth surface. Besides polishing are mainly used polishing tools, abrasive particles and other polishing media to process the product surface. Polishing cannot improve product’s dimensional accuracy or precision the geometry shape, but to obtain a smooth surface or specular gloss for the purpose, sometimes also use to eliminate gloss (matt). Usually buff as a polishing tool. Buff general make up by multilayered canvas, felt or leather stacked, both sides clamped circular plate with a metal, its rims coated with polishing agents which is mixture uniform by micro powder and oil other.
Polishing, high-speed rotation buff (peripheral speed 20 m/sec or more) pressed against to the molybdenum electrode, the abrasive effect on the product surface by rolling and micro machining to obtain a shiny finished surface, the surface roughness generally up Ra 0.63 to 0.01 microns. When using a non-greasy matt polish can matting shiny surfaces to improve the appearance.
According to the surface state of molybdenum electrode they can be divided into following categories: sintered molybdenum electrodes,forged molybdenum electrode, alkali cleaned molybdenum electrode, ground molybdenum electrode and polish molybdenum electrodes. These molybdenum electrodes types have similar physical and chemical properties. The different of them is degree of processing on the surface. And the degree of processing on surfaces the sintering molybdenum electrode machining at least, so that the surface more rough than others.
The polish molybdenum electrode machining intensity, the surface is shiny metal color, and is a high-quality interior and exterior, which are no status cracks.
