As an accredited technology enterprise with its own institute and talent academy, SUNFUN has completed more than ten national-level R&D tasks and undertaken major projects commissioned by agencies such as the NDRC, MOST, and MIIT.
Application fields: Suitable for optical spherical glass, optical crystals, and filters with a wear degree between 150 and 250 and relatively soft materials, such as LaF glass and blue glass.
Usage method:
Suggested specific gravity: 1.02 - 1.05, determined by the type of glass and process parameters.
Applicable machines: Flat high-throwing machine or spherical pendulum machine
Applicable workpieces: Spherical lenses with wear degrees ranging from 150 to 250 and high-precision plane glasses, such as LaF series glasses and blue glasses.
Features:
High precision: Uniform and narrow particle distribution, with the maximum particle size controlled to be less than 2 μm, suitable for products with high surface finish requirements.
Impurity-free: Multiple screening processes are adopted to remove impurities, ensuring that the product is free from scratches.
Good chemical stability: The product formula is set based on the characteristics of the glass, with strong targeting, which can reduce adverse effects caused by the high activity of the glass, such as water marks.
