Detailed Description
The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.
As shown in fig. 1-2, a wear-resistant steel-strip-reinforced polyethylene helical bellows comprises a bellows body 1, wherein the bellows body 1 comprises:
the core tube 2 is formed by winding a PE sheet into a tubular shape;
the steel belt 3 is arranged in a V-shaped structure and wound on the core pipe 2 in a uniform pitch;
the outer layer pipe 4 is made of PE sheets and uniformly covers the outer side of the steel belt 3;
the wear-resistant layer is made of GXCG-1101 and is uniformly coated on the inner wall of the core tube 2.
And adhesive resin 5 is arranged between the steel belt 3 and the core pipe 2.
The corrugated pipe body 1 is formed by compounding a core pipe 2 and an outer layer pipe 4 in a molten state under pressure.
When the device is used, firstly, an inner wall extruder co-extrudes a wear-resistant layer and a core pipe (PE inner pipe sheet), the wear-resistant layer and the core pipe are wound on a mandrel through the sheet to form a solid-wall core pipe, then, a steel belt pre-coated with bonding resin is formed into a V shape through a forming machine and a bending machine, then, the steel belt is wound on the core pipe according to a preset screw pitch on the mandrel, and a layer of PE (outer pipe) is extruded to cover a steel belt reinforcing material. Then the core pipe and the outer layer pipe in a molten state are compounded under a certain pressure in a short time, so that the core pipe, the steel belt and the outer layer pipe are compounded, and the pipe wall with an integral structure is formed.
The material of the wear-resistant layer is GXCG-1101, and the wear-resistant layer is a thermoplastic elastomer material with excellent wear resistance, the wear-resistant mechanism of the wear-resistant layer is similar to that of wear-resistant rubber and TPU elastomers, on one hand, the impact energy of solid particles is dissolved through elastic deformation, and on the other hand, when sharp particles scratch the surface of the material, the elastomers can effectively prevent cracks from extending.
GXCG-1101 shows more excellent wear resistance than wear-resistant rubber and TPU, because the strength (more than or equal to 20) and the elongation (more than or equal to 600%) of GXCG-1101 are far higher than those of wear-resistant rubber and TPU.
GXCG-1101 is polyolefin elastomer material, is nonpolar material, has chemical properties similar to HDPE and PP, is more suitable for being applied to a conveying pipeline of aqueous medium, can conveniently use a common extruder to realize composite co-extrusion with HDPE and PP, and has simple production process and reliable quality guarantee. Therefore, compared with TPU, GXCG-1101 has the advantage of higher cost performance.
In the production process of the corrugated pipe body, the inner side of the steel belt is precoated with bonding resin, namely, the steel belt is precoated with special resin as an intermediate layer of steel and plastic, which is the key for ensuring firm bonding of the steel and the plastic. And the best metal reinforcing effect can be obtained only if the steel and the plastic are firmly bonded together and any two layers are not separated.
The corrugated pipe can bear larger pressure in the pipe, is not afraid of corrosion of corrosive media in the pipe, particularly greatly improves the wear resistance, greatly improves the quality and the use reliability of the corrugated pipe, and simultaneously compared with a pure PE solid-wall pipe, under the same pressure-resistant condition, the steel belt reinforced polyethylene spiral corrugated composite pipe uses steel wires and belts to replace a large amount of polyethylene, saves high-energy consumption materials, reduces the cost and protects the environment. The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
