Description

Technical Field

[0001] The invention relates to the technical field of pipeline lining repair and treatment, in particular to a polymer fiber composite hose. Background Art

[0002] The service life of old pipes repaired by using the flipping method with composite hose lining can be extended by more than 30 years. The flipping method with composite hose lining to repair old pipes is to use a fiber-reinforced hose with an anti-permeability layer and impregnated with a special resin as the molding material of the new pipe, and the old pipe as the flipping channel and molding cavity of the new pipe. A special hose flipper is used to flip the hose and send it into the old pipe, so that the resin layer of the hose is attached to the inner wall of the old pipe, and the anti-permeability layer becomes the inner wall surface of the new pipe. The resin impregnated in the liner is solidified by heating or room temperature curing to form a composite pipe bonded to the original pipe.

[0003] At present, the flip-lined adhesive hose is divided into two types of composite hoses. One type is a polymer extrusion-coated polymer on a polymer fiber braided hose. After repair, the inherent capacity of the pipeline is strong, but its own structure is thin, and its ring stiffness and load capacity are poor. The other type is a polymer spray-coated hose on a polyester fiber short-filament non-woven fabric sewn into a hose. After repair, the material's own ring stiffness and load capacity are strong, but the pipeline's own pressure-bearing capacity is poor. Summary of the invention

[0004] The object of the present invention is to provide a polymer fiber composite hose to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solution: a polymer fiber composite hose, comprising a tube blank woven with polymer fibers and extrusion-coated with a polymer on one side, the tube blank being covered with a polyester fiber non-woven hose, and the polyester fiber non-woven hose being filled with glue and solidified during flip repair.

[0006] Furthermore, the inner side of the tube blank is a polymer fiber layer, and the outer side of the tube blank is an extrusion-coated polymer layer.

[0007] Furthermore, the production steps of the tube blank include:

[0008] A1, according to the inner diameter of the repaired pipeline, the polymer fiber is divided into warp and weft lines and a tubular polymer fiber layer of corresponding tight size is woven by a weaving machine;

[0009] A2, using an extrusion coating machine to extrude the heated high molecular polymer onto the outside of the high molecular fiber layer, and controlling the high molecular polymer to be extruded to 1 / 2 of the wall thickness of the cylindrical high molecular fiber layer, the high molecular polymer layer should completely cover the high molecular fiber layer and exceed a certain thickness;

[0010] A3, after completing the above process, the tube blank with single-side coating is manufactured.

[0011] Furthermore, the steps of making the polyester fiber non-woven hose include:

[0012] B1, cut the polyester fiber non-woven fabric seam according to the corresponding size of the circumference and length of the pipe to be repaired;

[0013] B2, the cut polyester fiber non-woven fabric is sewn into a tubular hose according to the corresponding size using a sewing machine;

[0014] B3, after completing the above processes, the polyester fiber non-woven fabric hose is manufactured.

[0015] Furthermore, the method for combining the tube blank and the polyester fiber non-woven fabric hose into a composite hose is: after brushing special glue on the outside of the polyester fiber non-woven fabric hose, it is dragged into the tube blank with special equipment, and then the tube blank and the polyester fiber non-woven fabric hose are extruded on the outside of the tube blank to be compounded together to form a single-sided extrusion-coated polymer fiber and polyester fiber non-woven fabric composite hose.

[0016] Furthermore, the method for combining the tube blank and the polyester fiber non-woven fabric hose into a composite hose is: the tube blank with a single-sided coating is turned over by a turning device, with the coating on the inside and the woven layer on the outside, and a special glue is applied in dots on the woven layer, and then pulled into the polyester fiber non-woven fabric hose, and then the tube blank and the polyester fiber non-woven fabric hose are extruded outside the polyester fiber non-woven fabric hose to be compounded together, and then the composite tube is turned over by a turning device to form a single-sided extruded polymer fiber and polyester fiber non-woven fabric composite hose.

[0017] Furthermore, the high molecular polymer is made of TPU.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are: a single-sided high molecular polymer is extruded onto the high molecular fiber layer, and a polyester fiber non-woven hose made of polyester fiber staple fibers is covered therein; a special resin is filled into the polyester fiber non-woven hose, and the resin is rolled through the non-woven composite hose layer made of polyester fiber staple fibers to be evenly penetrated onto the high molecular fiber braided hose. The pipeline repaired by this method not only has anti-corrosion and reinforcement functions, but also has better ring stiffness and load capacity. BRIEF DESCRIPTION OF THE DRAWINGS
