Application fields
Classical chemical polishing process, suitable for polishing optical spherical glass with a wear degree below 100, and flat glass polishing, such as quartz glass, fused quartz glass, etc.
Usage method
The recommended specific gravity is 1.05 - 1.13, which is determined by the material and process parameters of the glass.
Applicable machines: Flat high-throwing machine or spherical pendulum machine
Applicable workpieces: Spherical lenses with wear degree below 100, flat optical glass, such as fused quartz glass.
Features:
Large particles: The particle distribution is uniform with D50 > 1.5 μm, featuring fast cutting ability, and is suitable for hard optical materials.
Impurity-free: Through multiple screening processes to remove impurities, ensuring no scratches after use.
Easy to clean: By controlling the particle shape and adding additives, the product's surface is easy to clean after use.
