Abstract
A double-layer soft fabric-based fireproof pipe, with aluminum silicate yarn, nickel-chromium stainless steel wire, and carbon fiber as the fabric-based material, adopts a woven fabric structure to form a double-layer tubular fabric with a pipe diameter difference and is connected to each other. The space is filled with refractory material to make a fireproof tube, which protects the cables inserted into the inner tube. The refractory material is preferably asbestos fiber and aluminum silicate fiber. When burning at a flame temperature of 1100±50°C, the difference between the temperature inside the tube and the flame outside the tube can reach 400±50°C~800±50°C. Its manufacturing process includes the following steps: (1) The aluminum silicate / nickel-chromium stainless steel wires are parallel-twisted according to the number required by the fabric design, and the warping, sizing and drawing-in processes are performed to prepare for weaving. (2) Wind up the weft yarns required by the fireproof pipe respectively. (3) Choose multi-shuttle box loom or ordinary shuttle loom for weaving according to different yarn components. (4) After the double-layer pipe is off the machine, fill the filling material between the inner and outer pipes according to the designed filling density.
Description
technical field [0001] The invention belongs to the field of fireproof pipes, in particular to a double-layer soft fabric-based fireproof pipe. Background technique [0002] Various types of pipelines (such as drainage pipes, oil and gas pipelines, cables, and cables) are increasingly used in modern buildings, large-scale industries, and navigation and aerospace equipment. Such products are often used in complex and harsh environments, and they often need to be flame-retardant and fire-resistant. There is a great application demand for the development of pipeline protection layers with good environmental adaptability and high flame-retardant and fire-proof performance. [0003] Taking the cable as an example, its basic structure consists of four parts: core (conductor), insulating layer, shielding layer and protective layer. Among them, in addition to protecting the cables from external damage, the protective layer also needs to have a certain flame-retardant and fire-proof...
