Carbon fiber parallel electric tracing band

Abstract

The invention relates to the technical field of a carbon fiber parallel electric tracing band, in particular to a carbon fiber parallel electric tracing band which is environmental-friendly and durable and can be arbitrarily cut. A high-temperature resistant fiber weaving layer is arranged outside a carbon fiber, and the contact force between the carbon fiber at a gap and a bus can be improved; since the carbon fiber can bear a large pull force, heat generation pitch does not horizontally move after an external tension force is applied to the product; a conductive paint layer is coated between the bus and the carbon fiber, the adhesive force between metal and the carbon fiber is greatly improved, and the firmness between the bus and the carbon fiber is effectively guaranteed; the carbon fiber has extremely high tensile strength, the situations that the bus is turned over due to heat and the carbon fiber is further cracked are prevented; the carbon fiber does not have electromagnetic radiation, and no harm to a human body is generated; and with the design of a pitch gap, the electric tracing band can be arbitrarily cut, and the demands of different clients are satisfied.

Description

technical field [0001] The invention relates to the technical field of a carbon fiber parallel electric heating cable, in particular to an environmentally friendly, durable and arbitrarily cut carbon fiber parallel electric heating cable. Background technique [0002] Electric heating cables are mainly used for antifreeze and heat preservation of tanks, pipes, and tanks of industrial equipment, and can also be used for snow melting and ice melting of floor heating, ramps, roads, roofs, gutters, and downpipes. It is easy to install, easy to use, safe and reliable. [0003] At present, the parallel constant power electric heating cables on the market have the following defects: 1. The diameter of the heating wire is relatively thin, generally between 0.08-0.2mm, which results in small pulling force of the heating wire and small heating surface, and uniformity of heating The heating wire is not high, which leads to high surface load of the heating wire, high power per unit area...

[0003] At present, the parallel constant power electric heating cables on the market have the following defects: 1. The diameter of the heating wire is relatively thin, generally between 0.08-0.2mm, which results in small pulling force of the heating wire and small heating surface, and uniformity of heating The heating wire is not high, which leads to high surface load of the heating wire, high power per unit area, short life of the heating wire, and is particularly easy to blow out; First pulling, when the thinner heating wire is wound on two parallel busbars, and a gap is broken every 80-120cm long distance, when the heating wire is pulled, the elongation ratio of plastic and metal Not the same, the heating wire is easy to be pulled off; 3. When the existing parallel constant power electric heating cable is energized and heated, the thermal expansion ratio of the plastic and the metal is not the same, and at the same time, the two parallel busbars are wrapped around the heating wire, resulting in electromagnetic induction. Magnetic field, the busbar will turn over, causing the heating wire to break; 4. The gap between the heating wire and the busbar is soldered with tin, and the tin will be oxidized after long-term electrification, and the heating wire and the busbar have poor contact
