Description
Technical field
The utility model relates to a kind of tubing, especially a kind of plastic tube.
Background technique
In drainage pipes such as building construction, urban engineering project, generally adopted a kind of plastic winding tube.For example, China utility model patent ZL01216004.0 discloses a kind of large-aperture pipe wound with hollow belt, and this entwining tube is by the inside and outside two-layer tube wall that is bonded mutually with the square tube type hollow belt with its adhesive layer spiral winding side by side and be clipped in the hollow interlayer that the spiral between them communicates and constitute.Existing plastic winding tube normally adopts HDPE plastics (high-density polyethylene plastics) to make fully, and promptly the adhesive layer at the sidewall spacers place between the spiral rectangular tubular hollow belt and the bonding of twining and each spiral of being filled in the rectangular tubular hollow belt that twines shape in the shape of a spiral is the HDPE plastics.When making this entwining tube, normally will be Wrapping formed on the entwining tube molding machine of special use by the rectangular tubular hollow belt that the HDPE plastics are made, when the rectangular tubular hollow belt being imposed the coiling moulding, utilize extruder that the HDPE plastics of fusing are filled in sidewall spacers place between each spiral of the rectangular tubular hollow belt that twines shape in the shape of a spiral simultaneously, and then form HDPE plastic bonding obturator.Though above-mentioned existing entwining tube has plurality of advantages, find that in making and using the above-mentioned existing entwining tube that adopts the HDPE plastics to make fully still exists disadvantages such as cost is higher, intensity is on the low side, need further to improve.
The model utility content
The purpose of this utility model provides a kind of HDPE, PVC plastic compound winding pipe.
HDPE of the present utility model, the PVC plastic compound winding pipe has the entwining tube body, the tube wall of described entwining tube body is made of rectangular tubular hollow belt that twines shape in the shape of a spiral and HDPE plastics obturator, described HDPE plastics obturator bonding also is filled in sidewall spacers place between each spiral of the rectangular tubular hollow belt that twines shape in the shape of a spiral, the tube wall that it is characterized in that described rectangular tubular hollow belt is from the inside to the outside respectively by the PVC plastic layer, composite tack coat and HDPE plastic layer constitute, described composite tack coat be folded between PVC plastic layer and the HDPE plastic layer and with PVC plastic layer and the adhesion mutually of HDPE plastic layer.
In the utility model, described composite tack coat is to form by being easy to solidify with the mutually bonding tackiness agent of HDPE plastics and PVC plastics, as moulded the composite tack coat that obtains after other similar tackiness agent such as fat tackiness agent or the Guangzhou Lu Shan EP252 of company type compatibilizer, the CS-1 of E.I.Du Pont Company polymeric coupler etc. solidifies by the HDPE grafting.
In the utility model, except that the tube wall of the rectangular tubular hollow belt that is adopted was made of PVC plastic layer, composite tack coat and HDPE plastic layer respectively from the inside to the outside, the entwining tube body can directly adopt prior art and existing equipment to make.
With compare by the existing entwining tube of HDPE plastic production fully, HDPE of the present utility model, that the PVC plastic compound winding pipe has chemical resistance is excellent, is not corroded shock resistance, cold-resistant ageing-resistant, in light weight, easy to connect, wear-resisting, the liquid fluidity is excellent, good economy performance, ten big advantages such as non-environmental-pollution.Simultaneously, it also has following characteristic:
1, cost of material saving.HDPE is by 13000 yuan/ton, 5000 yuan/ton of PVC batches, and wherein PVC accounts for quality of product ground 2/3, and HDPE accounts for 1/3, so composite price is 7667 yuan/ton, than 5333 yuan/ton of pure HDPE saving costs.Even if HDPE double wall entwining tube 100% ground adopts reworked material in actual production, the HDPE reworked material is pressed 8500 yuan/ton price, and PE, PVC plastic compound winding pipe are also saved 2900 yuan/ton on cost of material.
2, because being 2 times of HDPE, the Young's modulus of polyvinyl chloride resin also wants many, so at assurance ring stiffness same size product up to standard, the Mi Chong of HDPE, PVC plastic compound winding pipe (being the weight of unit length) reduces.
The PVC quarter bend of the winding shape under 3, HDPE coats constitutes huge high-strength spring, according to spring element dynamics basic theories, solid-state properties that it is unique and dynamic response state have increased energy dissipation capacity, improved anti seismic efficiency, HDPE, PVC plastic compound winding pipe have better effectiveness in vibration suppression and anti-seismic performance.Influence of opposing foundation settlement and adaptation end load there are special advantage, have improved impact resistance.
4, HDPE, PVC plastic compound winding pipe are skeleton with the PVC quarter bend, cover outward that chemical property is extremely stable, the HDPE layer of tool gummed effect, efficient and the moment of flexure enhancing rate of flexural rigidity has been improved with the prestress system of rope and the structure of reinforcing mutually in novel inside and outside, has strengthened subjacent bed modulus and amount of deflection.
5, HDPE makes shell, PVC does supporting structure, the interaction of this shell structure and its supporting structure makes the contraction of homogeneous tube and the shrinkage of cement that more good linear relationship be arranged, can not resemble fully by the existing entwining tube of HDPE plastic production and concrete bonding bad, even deform or burst apart.
6, the PVC of the tool spring element performance quarter bend that spirals, the composite tack coat of big damping and the HDPE outer covering layer of high tenacity, make HDPE, PVC plastic compound winding pipe have good anti-fatigue performance, washing away of current or sandstone can produce load and vibration to tubing, these effects can expand in the boundary of backfill gradually, do not have paroxysmal variation, increase working life.
7, the PVC quarter bend makes that the whole process of production cooling and shaping is faster, has reduced energy consumption, has saved the energy.
8, because of 2/3 of HDPE, PVC plastic compound winding pipe quality of product is made of PVC, therefore PVC is not subjected to the influence of oil price fluctuation generally by carbide acetylene method production, and cost performance is better than the pure entwining tube of moulding of PE.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
