Abstract
The utility model relates to a high-rigidity polyethylene winding structure wall pipe, which consists of an inner wall layer and a covering layer, wherein the inner wall layer is a continuous solid wall pipe which is formed by spirally winding flaky polyethylene material strips and mutually lapping and fusing adjacent flaky polyethylene material strips; the covering layer is an outer convex reinforcing rib which is formed by covering a framework pipe with cambered polyethylene material strips and then winding on the outer surface of the inner wall layer; the outer convex reinforcing rib spirally crosses a lapping and fusing seam of the edges of every two adjacent flaky polyethylene material strips; the framework pipe is a polypropylene single-wall corrugated pipe; and the high-rigidity polyethylene winding structure wall pipe is characterized in that the diameter of the framework pipe is phi 81 mm to phi 150 mm. According to the high-rigidity polyethylene winding structure wall pipe, the weight of a product can be reduced by over 20 percent, the production efficiency is increased by 40 percent, the raw material consumption is low and the cost of the product is low to facilitate generalization and application of the product by rationally increasing the diameter of the framework pipe under the condition of reaching the same product design ring stiffness compared with the pipe manufactured by the conventional method.
Description
Technical field
The utility model belongs to the plastic tube manufacture field, particularly a kind of high rigidity polyethylene spirally enwound structure-wall tubular product.
Background technique
In the drainage works in city, the use of plastic tube is more and more.For improving the performance of opposing extraneous pressure, impact, need to multi-form stiffening rib be set in the tube wall periphery.At present, the plastic tube with stiffening rib mainly contains two kinds: a kind of is the direct extrusion molding mode, and it is the most representative to be double-wall corrugated pipe; Another kind is in helically-wound shaped mode, and it is the most representative to be double-wall pipe and polyethylene spirally enwound structure-wall tubular product.
Polyethylene spirally enwound structure-wall tubular product is hot technique entwining tube, it is take high-density polyethylene resin as main raw material(s), adopt hot winding shaping process, take polypropylene single-wall corrugated pipe (skeleton pipe) as auxiliary support structure, a kind of special construction wall pipe with higher critical external compressive resistance ability of making.Used polypropylene single-wall corrugated pipe (skeleton pipe) maximum caliber of current polyethylene spirally enwound structure-wall tubular product is φ 80mm.
Because the selection of pipe ring stiffness is an important indicator of plastic pipe design, so plastic tube need to improve its ring stiffness as far as possible.At present, produce high rigidity polyethylene spirally enwound structure-wall tubular product, particularly during the heavy caliber polyethylene spirally enwound structure-wall tubular product, usually taking following dual mode to improve ring stiffness: 1, to increase the number of plies of the continuous solid wall pipe that is wound in, namely increase the thickness of flat strip; 2, increase the requirement that the number of plies of twining the skeleton pipe reaches the product specification ring stiffness.The heavy caliber polyethylene spirally enwound structure-wall tubular product that existing mode is produced exists raw materials consumption many, and the winding time is long, the heavy and high outstanding problem of cost of product.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of raw materials consumption few, and the weight of product is lighter, high rigidity polyethylene spirally enwound structure-wall tubular product and production method thereof that the cost of product is low.
The utility model solves its technical problem and realizes by the following technical solutions:
A kind of high rigidity polyethylene spirally enwound structure-wall tubular product, consisted of by inner wall layer and clad, inner wall layer serve as reasons sheet shaped polyethylene strip spiral winding and each adjacent strip edge successively mutually overlap joint merge the continuous solid wall pipe that forms, clad is wound in the evagination stiffening rib that the inner wall layer outer surface forms after coating the skeleton pipe by arc polyethylene strip, the overlap joint of this evagination stiffening rib spiral cross-pressure in each adjacent sheet shaped polyethylene strip edge melts commissure, the skeleton pipe is the polypropylene single-wall corrugated pipe, it is characterized in that: the diameter of described skeleton pipe is φ 81mm～φ 150mm.
And the diameter of described skeleton pipe is φ 100mm-φ 125mm.
Advantage of the present utility model and beneficial effect are:
High rigidity polyethylene spirally enwound structure-wall tubular product of the present utility model, a kind of structural type that bore is the heavy caliber polyethylene spirally enwound structure-wall tubular product raising ring stiffness wall thickness of DN1200mm～DN4500mm that is suitable for, diameter by reasonable increasing skeleton pipe, reaching in the like products design ring stiffness situation, the tubing that the weight of product is made than existing methods can reduce more than 20%, manufacturing efficiency improves 40%, and make raw materials consumption few, the cost of product is low, thereby is conducive to applying of product.

Description of reference numerals:
1-arc polyethylene strip, 2-skeleton pipe, 3-sheet shaped polyethylene strip.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of high rigidity polyethylene spirally enwound structure-wall tubular product is made of inner wall layer and clad, inner wall layer serve as reasons sheet shaped polyethylene strip 3 spiral windings and each adjacent strip edge successively mutually overlap joint merge the continuous solid wall pipe that forms.Clad is wound in the evagination stiffening rib that the inner wall layer outer surface forms after coating skeleton pipe 2 by arc polyethylene strip 1.Evagination stiffening rib spiral cross-pressure melts commissure in the overlap joint at each adjacent sheet shaped polyethylene strip edge.The raw material of sheet shaped polyethylene material and arc polyethylene strip is high-density polyethylene resin.The skeleton pipe is the polypropylene single-wall corrugated pipe.
Innovation of the present utility model is: the diameter of skeleton pipe is φ 81mm～φ 150mm, and the diameter of skeleton pipe is preferably φ 100mm-φ 125mm.Reach the requirement of product different designs high ring rigidity by the diameter of appropriate design skeleton pipe.
The production method of this high rigidity polyethylene spirally enwound structure-wall tubular product is: take high-density polyethylene resin as main raw material(s), take the polypropylene single-wall corrugated pipe as auxiliary support structure, raw material is delivered to the arc polyethylene strip that heating in the extruder, plasticizing, homogenizing are extruded into respectively sheet shaped polyethylene strip by runner, mouthful mould and are coated with the skeleton pipe through the vacuum feeder, and sheet shaped polyethylene strip equidistantly is wrapped in and forms inner wall layer on the die surface.The arc polyethylene strip that is coated with the skeleton pipe is wrapped in the outside formation of inner wall layer clad, thereby makes finished product.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
