In order to improve the adhesion property between a steel wire and the polyphenylene sulfide, it's preferable that the steel wire is previously coated with an appropriate primer. When the paste-extrusion technique is employed, it is preferable that paste is ready by adding kerosene to polytetrafluoroethylene powder and kneading them, the paste is extruded to offer a tube under high stress and a stranded steel wire is coated with the tube, and after that, the stranded steel wire is dried and baked in a furnace akin to an electric furnace. As an illustration, a technique comprising ading the organopolysiloxane having an ultra-high viscosity and the organopolysiloxane having a decrease viscosity individually to the thermoplastic resin while heating and kneading the thermoplastic resin and uniformly dispersing them, a technique comprising including the organopolysiloxane, which is beforehand ready by mixing the organopolysiloxane having an extremely-high viscosity and the organopolysiloxane having a decrease viscosity in a prescribed proportion, to the melted thermoplastic resin and uniformly dispersing them, and the like will be exemplified. As an example, in case the scarcity of lubricants is generated as a result of lengthy period use of the control cable, there are some issues that the liner is thoroughly worn down and the operationability of the management cable is excessively lowered, and the like.
When the kinematic viscosity is less than 25 cSt, the organopolysiloxane having a lower viscosity is evaporated in a short time, and the put on and tear of the liner are generated during the control cable is used. Among them, polyoxymethylene is preferably utilized in the current invention as a result of a stickslip is hardly generated when polyoxymethylene is used. The management cable of the current invention comprises a conduit having flexibility, the inside floor of which being set up with a liner and an inner cable having an inside coat, and the interior cable is inserted into the conduit in order that the inner cable freely slides in the conduit as mentioned above. The conduit contains, as an illustration, a coiled spring produced by winding one or plural flat steel wires or round steel wires in abutting convolutions and an outer coat product of a artificial resin which covers the surface floor of the coiled spring.
Examples of the above-talked about polybutylene terephthalate are, as an illustration, a homopolymer of butylene terephthalate, a copolymer of butylene terephthalate and different monomer similar to ethylene terephthalate having a content material of the other monomer of at most about 10% by weight, and the like. The consultant examples of the organopolysiloxane having a lower viscosity are, for example, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like. Examples of the thermoplastic resin used within the above-talked about liner are, for example, polybutylene terephthalate, polyoxymethylene, polyamide represented by 1-nylon and 6,6-nylon, and the like, however the current invention is not restricted to the exemplified ones and other thermoplastic resins can be used as far as the article of the current invention could be achieved. As a way for forming an internal coat by using the polyphenylene sulfide, for instance, a melt-extrusion technique and an electrostatic coating methodology of powder may be cited. To the organopolysiloxane, as an illustration, an antioxidant, a corrosion inhibitor, excessive strain additives and the like might be added as occasion demands. Because the above-mentioned organopolysiloxane having an extremely-high viscosity, a linear organopolysiloxane, a branched organopolysiloxane and the like may be exemplified.
When the content material of the organopolysiloxane having an ultra-high viscosity is more than 85% by weight and the content material of the organopolysiloxane having a lower viscosity is less that 15% by weight, the effects do not differ much from the consequences when the organopolysiloxane having an ultra-excessive viscosity is used solely, and the development of load efficiency is little. It is preferable that the organopolysiloxane has a low viscosity so that the organopolysiloxane can easily extide from the resin. The polyoxymethylene is excellent in abrasion resistance and has a low abrasion coefficiency. Among the many thermoplastic resins used in the internal coat, polybutylene terephthalate, high density polyethylene, polyoxymethylene and polyphenylene-sulfide are particularly preferable as a result of these are glorious in abrasion resistance. The polyphenylene-sulfide is divided broadly into two teams of a crosslinked prepolymer and a linear prepolymer, and these will be utilized in the current invention. FIG. 1 is a partially-minimize-off perspective view displaying one embodiment of the control cable of the current invention.
