Example Embodiment
[0014] Example 1: Select polishing solution A (60% dodecanol, 12% deionized water, 28% polyethylene glycol octylphenyl ether) for KDP crystal polishing experiment: the pressure is 90kPa, and the rotation speed of the polishing disk is 100r / min , The polishing liquid flow rate is 10ml / min. After polishing for 20 minutes, the measured surface roughness was 1.73nm rms; the removal rate was 458.7nm / min.
Example Embodiment
[0015] Example 2: Select polishing solution B (54% dodecanol, 16% deionized water, 30% polyethylene glycol octylphenyl ether) for KDP crystal polishing experiment: the pressure is 90kPa, and the rotation speed of the polishing disk is 100r / min , The polishing liquid flow rate is 10ml / min. After polishing for 10 minutes, the measured surface roughness was 3.774nm rms; the removal rate was 823.7nm / min.
Example Embodiment
[0016] Example 3: Select polishing liquid C (45% dodecanol, 20% deionized water, 35% polyethylene glycol octylphenyl ether) for KDP crystal polishing experiment: the pressure is 90kPa, the rotation speed of the polishing disk is 100r / min , The polishing liquid flow rate is 10ml / min. After 8 minutes of polishing, the measured surface roughness was 10.87nm rms; the removal rate was 1831.2nm / min.
