Compared with the prior art, under the conditions of the same diameter and rupture strength, by means of the manufacturing technology of the ultra-high-molecular-weight polyethylene fiber rope externally wrapped with the HDPE, higher comprehensive physical and chemical properties are embodied.
Description
Technical field
The present invention relates to the superhigh molecular weight polyethylene fibers rope manufacture craft of a kind of outsourcing HDPE, belong to the soft rope technical field of synthetic fiber.
Background technology
Along with the progress of supra polymer technology, fiber rope substitutes steel wire rope extensive use.Wherein, the various hawser of boats and ships, pull rope, pull and be widely used with rope, in lifting field, elevator, the fields such as colliery, cordage is also being promoted gradually, but cordage can not substitute steel wire rope after all, and he is in ABRASION RESISTANCE, heat resistance, many aspects such as anti-extrusion, have its intrinsic shortcoming after all, and are restricted.
Patent " has synthetic fiber rope and the manufacture method thereof of sheath ", and the patent No. is ZL00100389.5, belongs to the technical field of cordage, and it discloses a kind of multiply multiple sheath kink method, and utilizes fixator strand or fiber to be fixed up.This fixing means makes the synthetic fiber rope intensity of sheath not high, is mainly reflected in wear-resisting and breaking strength.
Summary of the invention
The invention provides the superhigh molecular weight polyethylene fibers rope manufacture craft of a kind of outsourcing HDPE, is a kind of manufacture craft that have sheath, that retain high strength, have the fibrecord of the comprehensive physical such as high-wearing feature, anticorrosion shock resistance chemical property.
For solving above technical problem, the invention provides following technical scheme: the superhigh molecular weight polyethylene fibers rope manufacture craft of a kind of outsourcing HDPE, the material that the superhigh molecular weight polyethylene fibers rope of outsourcing HDPE comprises HDPE sheath and is wrapped in HDPE sheath inside is the cordage of ultra-high molecular weight polyethylene, and its manufacturing process steps is as follows:
A, rope making: by 12 strands of (or stereotyped writing) braiding machines, superhigh molecular weight polyethylene fibers rope is produced in braiding, and in rope making process, according to canonical measure, the diameter of cordage is greater than intended diameter;
B, 12 strands of (or stereotyped writing) cordage impregnating resins that will produce, keep the shape of cordage not loose;
C, oven dry: the moisture of cordage is dried completely or dries;
D, extruding: cordage is arranged on the extruding machine of transformation, makes cordage in extrusion process, remain 10% to 40% tension force; Then, evenly extruding HDPE sheath, and make it to keep shape to form sheath; Rapid water-cooled, shapes and lowers the temperature to cordage.
The superhigh molecular weight polyethylene fibers rope manufacture craft of this outsourcing HDPE that the present invention relates to, technique is simple, and by this technique, the superhigh molecular weight polyethylene fibers rope of this outsourcing HDPE that it is made, embodies higher comprehensive physical chemical property.
Accompanying drawing explanation
Fig. 1 is the superhigh molecular weight polyethylene fibers hitch composition of a kind of outsourcing HDPE of the present invention.
Detailed description of the invention
As shown in Figure 1, the material that the superhigh molecular weight polyethylene fibers rope of outsourcing HDPE comprises HDPE sheath 2 and is wrapped in HDPE sheath inside is the cordage 1 of ultra-high molecular weight polyethylene, in order to obtain the maximum tensile strength, adopt superhigh molecular weight polyethylene fibers rope, 12 strands are spliced and manufacture.12 strands to be spliced rupture strength high, and impact resistance is good, the non rotating when bearing pulling force, and 12 bursts of flower pattern and HDPE sheath adhesion strong, not broken lot when being hit, when sheath is rubbed, sheath is not easily separated with core rope, and mistake pulley phase is mutual compensatory good.HDPE Chinese is low pressure, high density polyethylene (HDPE), fusing point at 132 DEG C to 135 DEG C, density 0.941-0.965, there is higher hardness, mechanical strength and the corrosion of withstand large partial chemical medicine, good impact resistance, can-140 DEG C Celsius of low temperature-40F() use at temperature.
Concrete technical scheme is as follows:
First, by 12 strands of (or stereotyped writing) braiding machines, braiding production 12 strands of superhigh molecular weight polyethylene fibers ropes, in rope making process, the diameter of rope, according to canonical measure, is greater than actual diameter, considers the reduction volume when predraft for A, rope making.
B, 12 strands (or stereotyped writing) rope produced, impregnating resin, keep the shape of rope not loose, and increase the frictional force between fiber.
C, oven dry, dry the moisture of rope or dry, not retaining moisture, in order to avoid when extruding sheath, HDPE is bonding with fiber insecure.
First rope is arranged on the extruding machine of transformation by D, extruding, makes cordage in extrusion process, remains 10% to 40% tension force (applying pulling force as required); Then, evenly extruding HDPE makes it to keep forming sheath; Rapid water-cooled, shapes and lowers the temperature to cordage.
embodiment 1
Produce the band sheath cordage that a rupture pull force is greater than 100 tons, its diameter is not more than 38mm, diameter deviation ± 0.5mm, rope body waterproof, resistance to common strong acid, highly basic, and water glycol, hydraulic oil, lubricating grease, lubrication wet goods.Requirement, this rope was used for pulley high-speed drive, and have strong anti-load impact ability, wear Protection reaches under deadweight condition, and 25 kilometers pull, and can not expose ultra-high molecular weight polyethylene rope body fiber.
Through design, this rope 12 gangs of core rope diameter 36 ± 0.3mm, outer coated sheath controls at 1 ± 0.1mm.In process, first, through stranding, sennit, impregnating resin, dries and pre-stretch-draw, eliminates the structural stretch of rope, and be then arranged on the extrusion apparatus of transformation, apply tension force to rope, extrusion molding, cooling can be put in storage.
Beneficial effect through the band sheath cordage that above technique makes:
1, first, ensure that rope body rupture strength is greater than 100 tons, non rotating, under diameter 38 ± 0.5mm condition, reach a quite height.
2, the design's sheath, pulls frictional experiment through 25 kilometers, field compaction test, impact test, all reaches suitable ideal effect, and sheath waterproof, sand control, decreases the inner damage because of other factors of cordage.
3, select from selection, resistance to lubricating oil, hydraulic oil, water glycol and common strong acid, the corrosion of highly basic.
4, through crossing pulley breakdown test at a high speed, this structure has excellent transmission uniformity, repeatedly repeatedly suddenly stops, and does not occur the cores such as wrinkle, cover break-off.
In a word, compare with other patent structures, under same diameter and rupture strength, the present invention embodies higher comprehensive physical chemical property.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
