    摘要: Methods for curing a coating material, including a primary coating material, a secondary coating material, and a taping material, on an optical fiber. An optical fiber coating material having (A) 100 parts by weight of a polyether polyurethane bearing at least two ethylenically unsaturated groups with a Mn of 800-10,000, and (B) 1-40 parts by weight of a nitrogenous reactive diluent is cured by irradiating thereto electron beams, produced by driving electrons under an accelerating voltage of 50-190 kV, in a dose of 10-100 kGy. The method succeeds in effectively curing the optical fiber coating material into a cured coating having stable properties.

    摘要: An optical fiber is prepared by applying a liquid electron beam-curable resin composition to a bare optical fiber or a coated optical fiber having a primary or secondary coating on a bare optical fiber, irradiating electron beams to the resin composition on the optical fiber for curing while the optical fiber passes a zone under substantially atmospheric pressure, and providing a magnetic field and optionally an electric field in the zone for thereby improving the efficiency of electron irradiation. The method can comply with the increased drawing speed of the bare optical fiber and does not detract from the transmission properties of the optical fiber.
