Abstract

The invention discloses a preparation method and a preparation device of a negative-curvature hollow-core terahertz polymer waveguide tube, and the prepared waveguide tube can be infinitely long theoretically, so that the quality stability and batch production of a terahertz waveguide device are facilitated, and a low-price high-quality thin-wall waveguide tube device is provided for large-scale application of a terahertz waveguide communication system. The method comprises the following main implementation steps that 1, full drying is carried out on a granular optical polymer raw material; 2,the dried granular material is fed into a vertical single screw extruder, full heating and plasticizing are carried out under stirring and pushing of the vertical single-screw extruder, and a fluid material is formed; 3, forming and synchronous stretching are carried out on a waveguide tube prefabricated structure; and 4, winding and rolling are carried out on the negative-curvature hollow-core terahertz polymer waveguide tube.

Description

technical field [0001] The invention discloses a preparation method of a terahertz polymer microstructure waveguide, in particular to a preparation method and a preparation device of a negative-curvature hollow-core terahertz polymer waveguide. Background technique [0002] The existing terahertz polymer microstructure waveguide is prepared by a two-step method of drawing in a drawing tower after the preparation of a large-scale preformed rod. According to the different preparation methods of the preform, it can be divided into the stacking-stretching method and the extrusion-stretching two-step method. The method of manufacturing stacked preforms is mainly to use large-diameter polymer pipes to nest together several or hundreds of small-diameter pipes arranged in a certain order; the method of manufacturing extruded preforms is mainly to use extrusion The machine is connected with the preform rod mold, and the preform rod is made in the mold by thermoplastic extrusion mold...
