Fiber guide pipe with far-infrared heating function

Abstract

The invention provides a fiber guide pipe with a far-infrared heating function. The pipe wall is composed of a cover 1, a heat-insulation layer 2, a reflection layer 3, a heating layer 4 and a lining layer 6 from outside to inside, wherein the heating layer 4 comprises carbon fiber heating wires 5, the heat-insulation layer is made of 100% hole-sealed PMI rigid foam, the heat deformation temperature is 180-240 DEG C, the specific strength and specific rigidity are high, and the heat-insulation layer plays a role in heat insulation, heat preservation and support of the fiber guide pipe. The heating layer is an electric heat conversion layer containing pure black material carbon fiber heating wires, and the lining layer is a macromolecule layer with a self-lubricating function and mainly plays a role in reducing friction between conveyed fibers and the guide pipe. The fiber guide pipe with the far-infrared heating function has the advantages of being fast in temperature rise, uniform in heat radiation, long in service life and the like, the temperature can be raised to 135 DEG C within 3 minutes, and the requirement for rapid heating of on-line formation continuously fed fibers of light-weight high-strength composite materials.

Description
