Abstract
The utility model relates to an electric heating fiber line, comprising at least two bunches of polyester fiber, a bunch of carbon fiber and an insulating layer. The fibers are provided with twist DEG and are twisted along the same direction when being twisted together. The electric heating fiber line can use safe voltage which is below 36V of the alternating and direct current and has the advantages of good line form, good fire-proof performance, high strength, less power consumption, and low cost.
Description
The utility model relates to a kind of electrothermal fibre thread, especially includes the electrothermal fibre thread of carbon fiber, polyster fibre and insulating barrier.
Present employed electrothermal fibre thread mainly is with cotton by carbon fiber, hair or flaxen fiber are made line, and be provided with insulating barrier, its shortcoming is as the cotton that strengthens auxiliary material, hair or flaxen fiber are at high temperature resistant, rub resistance, tensile strength, aspects such as anti-flammability all exist deficiency, and carbon fiber and cotton, when hair or flaxen fiber are plied to line, because its fiber is not done any twisting before these fiber strands, so after being plied to line, the one-tenth of its line is twisted with the fingers bad, and its insulating barrier is the material that contains venomous injurant.
The purpose of this utility model is exactly the shortcoming that overcomes above-mentioned existing electrothermal fibre thread, and the electrothermal fibre thread of a kind of high temperature resistant, rub resistance, tensile strength height, good flame resistance is provided.
The purpose of this utility model realizes by following structural measure, electrothermal fibre thread of the present utility model mainly includes a branch of thermal emissivity rate height, good toughness, anticorrosive, resistance to oxidation, save the carbon fiber of power supply, at least two bundles or three beams or more high temperature resistant, rub resistance, the tension intensity height, the polyster fibre of good flame resistance, carbon fiber and polyster fibre all have the twist, and are (promptly are both Z and twist with the fingers, or be both the S sth. made by twisting) of equidirectional twisting, carbon fiber and polyster fibre are plied to line, and they are that fiber is twisted with the fingers and to be twisted with the fingers into strand to equidirectional and in its line outside one insulating barrier is arranged; This insulating barrier can be that to have cohesive force strong and insulation and fire resistance are arranged, and wear-resistant, pliability is good, and the polyester glue of no side effects perhaps can be ultrathin polyester film, and this polyester film is coated on line; The carbon fiber fineness degree is that 1 carbon fiber to 3K(1K unit has 1000 carbon fiber wires), resistance value is 180 Ω to 450 Ω/rice, its continuous length is not less than 400 meters, 400-800 rice preferably, this length requirement is in order that in that to add the loss in man-hour little, and the fineness degree of described polyster fibre is identical with the carbon fiber fineness degree basically.
The utility model is made heater with carbon filament, after the alternating current-direct current safety of using below 36 volts, can be used for daily necessitiess such as under blanket, electric blanket, electric pad, small-sized warmer and clothes as heater element, also can be used for simultaneously on the industries such as industry, medical, high-tech and national defence.Electrothermal fibre thread cost of the present utility model is low, making is simple, and applied range is not afraid of violent rubbing, and can roll over bendable, and the life-span is long, good flame resistance, and consumed power is little, and the line of needn't worrying to generate heat breaks or punctures insulating barrier and causes the accident.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is the structural representation of electric wire of the present utility model;
Fig. 2 is the structural representation of another embodiment of electric wire of the present utility model.
1 is electric wire among Fig. 1,2 is carbon fiber, 3 is polyster fibre, 4 is insulating barrier, in electric wire 1, it comprise polyster fibre that two bundles (or three beams) have a twist with a branch of have the twist and with the sth. made by twisting of polyster fibre to identical carbon fiber, described two bundle polyster fibres and a branch of carbon fiber twisted together, this line sth. made by twisting to the sth. made by twisting of its fiber to identical, in the outside of its twisted line one insulating barrier is arranged, this insulating barrier is made of a kind of polyester glue, and this polyester glue is applied on the line, forms an insulating barrier, this polyester glue should have non-toxic nature, characteristics such as formed insulating barrier is to have fire resistance, and is wear-resistant, and flexibility is good, another effect of smearing polyester glue is to make the line body structure tight, bond together securely, thereby can make full use of the heat conduction and the thermal radiation function of main material, and strengthen practical stability.Described insulating barrier also can be made of ultrathin high pressure polyester film, and its thickness is 0.001 to 0.01mm.Among another embodiment described in Fig. 2, coat one deck dacron thread 5 again, so just can improve the wear resistence and the characteristics such as tensile strength and further insulation of its electrothermal fibre thread, be more suitable in special purposes in the insulating barrier outside of its line that forms.
Claims (5)
