Embodiment Construction
[0026] The technical solution of the present invention is described clearly and completely below, obviously, the described embodiments are only some embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0027] The photocurable resin contains active functional groups, which can initiate a polymerization reaction by a light initiator (light initiator) under ultraviolet light irradiation to form a three-dimensional cross-linked lattice solid. Combined with reinforcing fibers, light-cured composite materials can be manufactured.
[0028] Such as figure 1 As shown, the directional drilling penetrates the pipeline anti-corrosion layer, and an outer coating structure is provided outside the pipeline 1. The outer coating structure is composed of an anti-corrosion layer 2 and a c...
