Final polishing Film

Grish Final polishing Film is specially researched and developed for the final
polishing of optical fiber connector. It is composed of nanometer silica
particles mixed with high efficiency adhesive, evenly coated on the surface of
polyester film, after drying and curing reaction. Because the polished original
particles are fine and the particle size is smaller than the wavelength of
visible light, they are evenly distributed to form a transparent or translucent
abrasive paper. The Final polishing Film only needs to add purified water as
the polishing medium. During the polishing process, the nano-coating of the
polishing piece will gradually release the polishing particles and participate
in the polishing effect, so that the end face of the fiber reaches a high
degree of smoothness. The Final polishing Film can be reused many times, but
depending on the type of polisher, conditions, and quality requirements, the
number of times they are used varies. SO-01L, SO-01M and SO-01H series are
GRISH new generation polishes. The improved products have higher polishing
efficiency and grinding yield. The different polishing forces of the three
products can meet different process conditions and grinding requirements.

Features of Final Polishing Film

1. High efficiency with good polishing ability;

2. Long Lifetime can greatly save costs;

3. Provide the stable fiber height.


Using Method
1. Make sure there are no abnormal deep scratches or defects on the end face of
the optical fiber after precision grinding of D1;

2. Thoroughly clean the grinding machine fixture and rubber pad and other
parts, especially ensure the rubber pad surface intact, no foreign matter;

3. Spray an appropriate amount of purified water on the surface of the rubber
pad, wipe it evenly with dust-free paper, and immediately stick the polish on
the surface after the surface is dry;

4. Spray a small amount of pure water evenly onto the surface of the polish and
wipe it evenly with dust-free paper to drive out the air below the polish

5. Purge the surface of the polish with compressed air to remove dust or
foreign matter;

6. Then spray the surface of the polishes evenly with an appropriate amount of
pure water

7. Gently release the connector fixture so that the connector end face is in
even contact with the polishing plate, apply appropriate pressure, set the
polishing time, and start the grinding machine to start polishing

8. After the grinding machine stops working, carefully remove the fixture, take
out the polishing plate, and dry it for reuse
