Green Silicon Carbide 4000# for Fiber Polishing?
Silicon carbide is a very hard (Mohs hardness of about 9.3, basic diamond and cubic boron) and targeted artificial abrasive.
Grain size: 4000#.
The “#” here stands for “mesh”, which is a standard unit of abrasive particle size.
4000 mesh belongs to the ultra-fine particle size range. This grade of abrasive particles is very small and is mainly used for fine grinding and final polishing, rather than coarse grinding or extremely large amounts of material.
The particle size of 4000 mesh is approximately between a few microns and more than ten microns (the specific value depends on different standards, such as FEPA JIS, etc., but they all belong to the ultra-fine range).
Function:
Remove micron-level scratches: Remove tiny scratches left by the previous process (such as using 2000# or 3000# abrasives).
Usage:
Usually used in the form of polishing liquid/polishing paste.
Mix 4000# green silicon carbide micropowder with water or special polishing lubricant/coolant to make a suspension.
Add this polishing liquid to the polishing disc covered with polishing film/polishing pad.
The ceramic ferrule end face of the fiber optic connector is fixed in the fixture and pressed on the rotating (or swinging) polishing disc at a specific pressure and angle for polishing.
