The utility model relates to a polyethylene reinforced pipe with fibrage reinforced strips, which mainly comprises an inner layer and an outer layer, reinforced strips are arranged between the inner layer and the outer layer, the adjacent layers in multiple layers of the reinforced strips are oppositely and cross-helically wound on the outer wall of the inner layer. With a wrap angle of 54 degrees and 44 cents or so between the reinforced strips and the axial cord, the reinforced strips are across-wound on the outer wall of the inner layer backward and forward. The tensile strength of the reinforced strips is higher than the tensile strength of the inner layer and outer layer, and the inner and outer layers of the pipe and the reinforced strips are bonded or welded in one piece. The polyethylene reinforced pipe with fibrage reinforced strips has the beneficial effects that the manipulation is easy, the replacement of the product structure is easy, the adaptability is wide and the like, moreover, aiming at the needs of manufacturing products with various pressure grades, the methods of varying the layer number of the fibrage reinforced strips and changing the number of winding layers are adopted to achieve the operating requirements.

Description

The polyethylene of fibrage reinforcing band strengthens tubing
Technical field
The utility model relates to the plastic tube field, mainly is that a kind of polyethylene of fibrage reinforcing band strengthens tubing, is applied to feedwater, draining, and combustion gas, chemical industry, oil, rock gas, agricultural, ground electric power pipe is buried, fields such as optical-fibre communications in the mine.
Background technique
Common polythene tubing is single polyethylene manufacturing, and not only consumptive material is many, and the tubing voltage endurance capability is low.The polyvinyl piping materials that aramid fibre of the prior art strengthens adopts aramid fibre is manufactured reinforcing band with the polyethylene coating, is coated on the making method that the polyethylene outer wall of inner tube then coats the polyethylene pipe outer wall again.This method affects for promoting the use of of polyethylene reinforced pipe because aramid fibre costs an arm and a leg, and the fabricating cost height is added reinforcing band working process complex process.
The model utility content
The utility model purpose is exactly the deficiency that will overcome above-mentioned technology, and provides a kind of polyethylene of fibrage reinforcing band to strengthen tubing.
The utility model solves the technological scheme that its technical problem adopts: the polyethylene of this fibrage reinforcing band strengthens tubing, mainly by internal layer and outer the composition, be provided with reinforcing band between internal layer and the skin, be wrapped in the outer wall of internal layer with opposite interlocking of Hand of spiral between the adjacent layer of multilayer reinforcing band.
Between described reinforcing band and the axis with 54 ° 44 ' about forward and reverse intersection of wrap angle be wrapped in inner layer outer wall.
The tensile strength of described reinforcing band is higher than internal layer and outer field tensile strength.
Bonding or welding is an one between described tubing skin and internal layer and the reinforcing band.
The effect that the utility model is useful is: this fibrage reinforcing band of the utility model, mode with the reverse intersection of adjacent layer is wound in the polyethylene inner tubal wall outside, be to guarantee the equilibrium of goods axial strength and radial strength, between reinforcing band and the tubing axis with 54 ° 44 ' about the angle arrangement.Meanwhile, adopt the method for hot melt knot, fuse into one between pipe and fibrage reinforcing band and the fibrage reinforcing band in making, then making inside and outside tube wall and the clinkering of fibrage reinforcing band at outer fibrage reinforcing band outer wall coating polyethylene outer tube wall is one.Compared with prior art, the utlity model has simple to operately, article construction is changed easily, advantages such as wide adaptability at the goods requirement of different pressures grade, can adopt the conversion fibrage reinforcing band number of plies, and the method that changes winding layer quantity, reach usage requirement.Adopt the staggered winding of fibrage reinforcing band, under with equal pressure requirement situation, can save the polyethylene raw material greatly, and can reach the inaccessible working pressure of common polythene tubing, the less tubing goods (250mm is following) of specification can also be made the plate-like product, reduce pipe joint, dwindle the construction period, save operating expenses.

Fig. 2 is a sectional structure schematic representation of the present utility model;
Description of reference numerals: internal layer 1, skin 2, reinforcing band 3.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As depicted in figs. 1 and 2, the polyethylene of this fibrage reinforcing band strengthens tubing, mainly form by internal layer 1 and outer 3, be provided with reinforcing band 2 between the internal layer 1 and outer 3, be wrapped in the outer wall of internal layer 1 with opposite interlocking of Hand of spiral between the adjacent layer of multilayer reinforcing band 2, extrude processing through twice, multi-layer structure is closely as one, and has certain elasticity, course of working can be batched and is plate-like, outer 3 and internal layer 1 and reinforcing band 2 between bonding or welding be one, the tensile strength of reinforcing band 2 is higher than the tensile strength of internal layer 1 and skin 3.
Be the axial strength of assurance goods and the equilibrium of radial strength, between reinforcing band and the axis with 54 ° 44 ' about the wrap angle positive and negative direction intersect and be wrapped in internal layer 1 outer wall, meanwhile, adopt the method for hot melt knot, fuse into one between pipe 1 and fibrage reinforcing band 2 and the fibrage reinforcing band 2 in making, then at fibrage reinforcing band 2 outer wall coating polyethylene outer tube walls, making internal layer 1 outer tube wall and outer 3 inner tubal walls and 2 clinkerings of fibrage reinforcing band is one.Extrude processing through twice, the plastic materials of outer 3 plastic tubes and internal layer 1 plastic tube can be with reinforcing band 2 bonding or welding be one, strong bonded.
Make good polyethylene inner layer 1 outer wall according to 54 ° 44 ' about the forward and reverse intersection of wrap angle twine fibrage reinforcing band 2, should remove the moisture that internal layer 1 outer pipe wall adheres to before coating, and heating tubing makes its outer wall top layer fusion, so that with winding layer welding in the reinforcing band 2, equally, behind the winding layer, the winding layer outer wall makes its external layer fusion in the heating reinforcing band 2 in having twined reinforcing band 2, twine reinforcing band 2 outer wraps again, make the 2 winding layer weldings of two reinforcing bands.Reinforcing band 2 winding layers are one group with the positive and negative direction intersection, and according to the requirement of withstand voltage of tubing, reinforcing band 2 winding layers can be one or more groups, and the operating method of every winding one deck all is identical, so that the mutual welding of interlayer.(, can specifically select the heating setting of each interlayer) according to the technology capability of hot melt adhesive.
Tubing through twining the fibrage reinforcing band coats the outer layer polyethylene tube wall through extruder and extrusion die under the situation of same heating outermost surface outer wall, tubing cooling after the coating is after traction, reel, be cut into the plate-like product, also directly fixed length cutting is a straight tube.The tensile strength of fibrage reinforcing band 2 is higher than the tensile strength of plastic tube matrix.The braided fiber of braiding reinforcing band 2 can be a terylene, the yarn that polyamide fibre or other fibers are made, and the structure of braiding reinforcing band 2 can be single layer structure, also can be double-deck, three layers or other multi-layer structures.The fibrage reinforcing band needs dip-coating to meet the hot melt adhesive of technological requirement.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
