Preparation method and device of far-infrared water-based carbon fiber heating wire

Abstract

The invention belongs to the technical field of far-infrared electric heating, and more specifically relates to a preparation method and a device of a far-infrared water-based carbon fiber heating wire. According to the far-infrared water-based carbon fiber heating wire, uniform bonding of conductive coating on the surface of the far-infrared water-based carbon fiber heating wire is realized without caking. The preparation method comprises following steps: (a) a carbon molecular bonding layer is formed on the surface of an original wire; (b) homogenization of the thickness of the carbon molecular bonding layer is carried out; (c) carbonization of the original wire coated with the uniform carbon molecular bonding layer is carried out; and (d) resistance measurement of the carbonized bonding wire is carried out. The device comprises a nano bonding unit, a uniformizing unit, a carbonizing unit, and a resistance measurement unit. According to the preparation method and the device, the surface of the original wire is uniformly coated with the water-based conductive coating, the heating wire with high thermal electrical conductivity and a balanced resistance value is obtained; and in temporary production interruption, setting speed of the bonding layer is low, and quality management is convenient to realize.

Description

technical field [0001] The invention belongs to the field of far-infrared electric heating technology, and in particular relates to a preparation method and a device of a far-infrared water-based carbon fiber heating wire uniformly bonded on the surface without congealing into a block. Background technique [0002] Generally speaking, the electrothermal film is a heating element in the shape of a thin pad built-in plate that relies on electric current to generate heat. It has the advantages of easy temperature adjustment, no air pollution, very hygienic and no noise. Therefore, it is widely used in various aspects such as heating pads, heating stickers, mattresses, thermal insulation quilts, thermal insulation blankets, and residential heating facilities in residential quarters and general residences. It can also be used in heating facilities for commercial buildings such as offices or shops, construction sites or Heating facilities for industrial construction such as tents,...

AI Technical Summary

Problems solved by technology

[0005] However, during the production process of the heating wire of the above-mentioned conventional technology, when the fibers pass close to the drum with the conductive paint or pass through the deep groove with the conductive paint after immersion, the conductive paint will condense into lumps, causing the glass fiber The uniform thickness cannot be bonded, and uneven bonding will lead to problems such as reduced flexibility and uniformity of the heating wire, unfixed formation of the heating layer, excessively wide range of resistance changes, reduced heating effect, and excessive electronic consumption.
