Problems solved by technology

Its shortcomings are: slow pultrusion line speed, low production efficiency; easy to break, low yield; high mold manufacturing costs, large electric heating capacity, high energy consumption
The first defect is that the ultraviolet rays emitted by the ultraviolet lamp tube are not used except for being reflected by the reflector, and the rest escape from the gap outside the reflector.
The second is that the processed products must be light-cured through the focus, which limits the number of processed products in the furnace, resulting in low production efficiency
[0004] In addition to the above, in the traditional one-time molding light curing process, the resin is in a fluid state and sags in the initial stage of the glue line that is extruded after being extruded by the cavity and subjected to ultraviolet light, and the glass fiber is released from the extrusion stress. Discrete on the outside, resulting in irregular appearance of the cured composite and insufficient internal structure

Description

technical field [0001] The invention relates to a strengthening member for an optical cable and a production device and method thereof, belonging to the technical field of optical cable materials. Background technique [0002] At present, glass fiber reinforcements for optical cables are usually made of thermosetting resin as the matrix material and glass fiber as the reinforcing material, and are prepared by thermosetting pultrusion molding process. Its shortcomings are: slow pultrusion line speed, low production efficiency; easy to break, low yield; high mold manufacturing costs, large electric heating capacity, high energy consumption. [0003] At present, light curing technology has been widely used in printing, coating and other fields. The light curing furnace used in the pultrusion curing process is equipped with one or two arc-shaped reflectors in the furnace cavity, and the ultraviolet rays emitted by the ultraviolet lamp are The reflective plate is emitted to form...
