Abstract:
In a composite of a vulcanizable rubber or rubber-like composition with one or more metal reinforcement elements embedded therein, the metal reinforcement element is coated with a polymer or non-cured rubber composition compatible with and co-polymerizable, co-vulcanizable or crosslinkable with said vulcanizable rubber composition to be reinforced, and additionally bearing functional groups either covalently bonding to the metal surface of said reinforcement element or forming covalent bonds with the outward directed first functional groups of a mono- or multimolecular layer of a bifunctional adhesion promotor intercalated between said metal and said coating and bound to said metal by its second functional groups. A cured rubber or rubber-like product, for instance a pneumatic tire, is obtained by vulcanization of such a composite.
Abstract:
A rope (10) comprising an inner portion (10a) comprising a plurality of multifilament fibers (100) in the length direction of the rope (10) and a woven jacket portion (10b) covering the inner portion (10a). The woven jacket portion (10b) contains a plurality of monofilament fibers (200) in the length direction of the rope (10) and at least one multifilament fiber (300) in the circumferential direction interwoven with the monofilament fibers (200). The monofilament fibers (200) of the woven jacket portion (10b) form the majority of the outer surface of the rope (10). The rope (10) can be used as a pulling rope facilitating the positioning of elongate items, such as electrical or optical cables within conduits (510) or protective sleeves (520).
Abstract:
A rope (1) is described, in particular for controlling at least one wing profile, comprising at least one thread (11) and strands (21, 31) made of metallic or plastic material, as elements supporting a tension load, wherein the rope (1) comprises at least one substance (12, 22, 32) coating, and preferably impregnating, the threads+ and strands (11, 21, 31), such substance being, adapted to prevent a mutual contact between the threads and strands (11, 21, 31) and to compensate, through its own elastic deformation, a relative elastic deformation between the threads and strands (11, 21, 31), in which the substance (12, 22, 32) is adapted to fill interstices (13, 23, 33, 43) between the threads and strands (11, 21, 31) making the rope (1) compact, and the substance (12, 22, 32) is at least one elastomer.
Abstract:
A wire rope (20) comprises a central core (27), a plurality of outer elongated elements (26) surrounding said central core (27), a polyamide or a polyether block amide (PEBA) coating (22) applied on said central core and said outer elongated elements, and a thermoplastic polyurethane (TPU) coating (24) covering on said polyamide or said PEBA coating (22). The method of manufacturing such a wire rope (20) is also disclosed.
Abstract:
An elongated steel element adapted for the reinforcement of rubber products is covered with a ternary alloy or quaternary alloy coating of copper-M-zinc. M is one or two metals selected out of the group consisting of cobalt, nickel, tin, indium, manganese, iron, bismuth and molybdenum. The copper content inside the coating ranges from 58 weight per cent to 75 weight per cent. The content of the one or two metals inside said coating ranges from 0.5 weight per cent to 10 weight per cent. The remainder is zinc and unavoidable impurities. The one or two metals are present throughout the coating. Phosphorus is present on and/or in the coating in an amount of more than 1 and less than 4 milligram per square meter of the coating. The coating further comprises one or,ore compounds which complex with the copper in the coating to form an insoluble film on its surface. Good results are obtained for steam ageing and cured humidity adhesion. Furthermore, a corresponding method for manufacturing such an elongated steel element is disclosed.
Abstract:
A method for manufacturing a component includes a step of providing at least one metallic element. A surface of the at least one metallic element is modified to facilitate a bonding of the at least one metallic element to a polymeric layer. The polymeric layer is then bonded to the at least one metallic element to form the component.
Abstract:
The present invention provides an ultrahigh molecular weight polyolefin fiber coated with a coating composition, wherein the coating composition contains a UV stabilizer, characterized in that the amount of UV stabilizer is between 2 wt% and 80 wt.% compared to the total weight of the coating composition based on solids. The UV absorber can be selected from the group consisting of hydroxybenzophenones, hydroxyphenylbenzotriazoles, oxalanilides, phenyl esters, benzooxazinones, cyanoacrylates, formamidine, benzylidene malonates and hydroxyphenyl triazines and combinations thereof. Such fibers are particularly useful in ropes and fishing nets.
