Production process and production line of high-strength fiber knitting and extruding pipeline

Abstract

The invention provides a production process and a production line of a high-strength fiber knitting and extruding pipeline. According to the production process and the production line, the glue coating mechanism is adopted to glue a glass fiber cloth woven by glass fiber, then the glass fiber cloth is directly wrapped through a coating mechanism, and a woven fiber layer formed through weaving theglass fiber is replaced, so that the thickness increase of a fiber hooking connection caused by hooking and weaving is avoided, and thickness of the inner layer and the outer layer of a glass fiber tube is reduced, and strength of the winding layer is improved. According to the production process, after the glass fiber cloth woven through the glass fiber is glued, the glass fiber cloth is directlywrapped to replace the woven fiber layer formed through the glass fiber hooking, so that thickness increase of the fiber hooking connection caused by hooking and weaving is avoided, the thickness ofthe inner layer and the outer layer of the glass fiber tube is reduced, the strength of the winding layer is improved, and the technical problem that the thickness of the winding layer caused by innerand outer layer glass fiber weaving is too low is solved.

Description

technical field [0001] The invention relates to the technical field of production and preparation of reinforced thermoplastic pipes, in particular to a high-strength fiber braided and pultruded pipe production process and a production line thereof. Background technique [0002] At present, the high-pressure reinforced thermoplastic pipes in the world can be divided into two categories. One is aimed at improving the ability to resist internal pressure. It is usually a three-layer structure, the inner and outer layers are various thermoplastics, the middle layer is various fibers or metals as reinforcement materials, and the fiberglass tube is the most representative reinforcement material, glass fiber tube is also called glass fiber tube, as the name implies It is to add glass fiber to the reinforcing material of the middle layer. The molding process is to impregnate glass fiber filaments with resin, cure them in a high-speed polymerization device integrating photoelectricit...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned patent discloses a glass fiber tube by setting an inner layer, a longitudinal reinforcement layer, a hoop reinforcement layer, and an outer layer formed by braiding and winding of fibers to strengthen the strength of the glass fiber tube, but the longitudinal reinforcement of the winding The thickness of the layer and the hoop reinforcement layer is too thin, and the strength of the glass fiber tube is low
