Abstract

The utility model relates to a novel electric heating band made of electrothermal non-metal fiber, which comprises carbon fiber electrothermal wires. A high temperature resistant insulating layer is coated out of the electrothermal wires. The electrothermal wires and the fiber are weaved into a weaving layer. The periphery of a rubber protective layer positioned at the periphery of the weaving layer is a protective layer with waterproof and fireproof performance. The utility model has high thermal efficiency, firmness, convenient operation and wide purposes, is capable of ensuring temperature to be enhanced for more than 50% when wound on a pipeline.

Description

Novel metalloid fibre electroheating heating tape

The utility model relates to a kind of novel metalloid fibre electroheating heating tape, particularly a kind of carbon fiber heating tape.

Nonmetallic electrothermal fibre thread generally is meant carbon fiber electrothermal line, and using more at present is the heating element of making electric blanket, and this carbon fiber heating element exists connection, problem such as fixing, it is not too convenient to assemble, influence is applied, and therefore, is necessary to provide a kind of heating member easy to use.

The purpose of this utility model provides a kind of novel metalloid fibre electroheating heating tape, and this is with good heat insulating, and is firm, easy to use, applied range.

For achieving the above object the utility model by the following technical solutions: a kind of novel metalloid fibre electroheating heating tape comprises: carbon fiber electrothermal line, the peripheral temperature-resistant insulation layer that coats of this heating wire, the braid of the carbon fiber electrothermal line weave in of fiber and coating temperature-resistant insulation layer; Be positioned at the rubber sheath of braid periphery; Outermost is tool waterproof, fire protecting performance protective layer.

The utility model is described in further detail below in conjunction with accompanying drawing.

Among Fig. 1, Fig. 2; 3 is carbon fiber electrothermal line; its periphery is coated with temperature-resistant insulation layer; poly tetrafluoroethylene for example; adopt the heatproof fire proofing firbre, for example rock wool etc. is made into braid with the carbon fiber electrothermal line that above-mentioned periphery is coated with temperature-resistant insulation layer, is surrounded by the anti-caoutchouc sheath 2 of heatproof outside braid; outermost one deck is fire-proof and water-proof protective layer 1, for example protective cloth.

Among Fig. 3, electrothermal fibre thread 3 is the series connection form, 6 is tie-point, among Fig. 4,5 is an end of power line, zero line for example, and the other end be phase line 5 ', have 6 heating wires to be arranged in parallel among the figure, wherein each bar heating wire compartment of terrain is furnished with tie-point 6, connects between the adjacent tie-point, wherein line one end and power line one end 5 join, adjacent line one end and the power line other end join, and adjacent two lines constitute a heating sections, as a among the figure, b, c, d represents the first heating sections respectively, the second heating sections, the 3rd heating sections, the 4th heating sections.The thickness of carbon fiber electrothermal line is at 3K-12K among the figure, and the length between the node is between 20-30m, and power supply can be 220 volts or 380 volts.(K represents that every heating wire section has 1000 carbon fibers and other fibrous twisted wire usually).

The utility model advantage: the braid that carbon fiber electrothermal line is become with fibrage, and braid The connection of middle heating wire can be serial or parallel connection, especially adopts modular heating sections, can be according to need Accept or reject, easy to install, rubber cover and the most peripheral fire-proof and water-proof are arranged outside braid The protective cloth layer, make product firm, serve many purposes, for example the heating tape of the following width of 10cm can Be wrapped on the pipeline and use, can make temperature improve more than 50% thermal efficiency height.
