AI Technical Summary
During the grinding process of ultra-low oxygen gas rods, high temperature and contact with air cause oxidation of the sample surface, affecting the accuracy and stability of the detection and failing to meet the purity detection requirements of high-end metal materials.
An acetone droplet assembly is used for cooling and air isolation. Combined with the abrasive compatibility of diamond files and silicon carbide sandpaper, the temperature and oxidation risk during the grinding process are controlled. The acetone droplet assembly forms a liquid film at the grinding interface to isolate air contact. With appropriate rotation speed and abrasive parameters, efficient decontamination and cooling of the sample surface can be achieved.
It significantly reduced the standard deviation of oxygen content detection to within 0.000015, improving the accuracy and stability of detection and meeting the purity testing needs of high-end metal materials in aerospace and other fields.
