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

Abstract

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. The preparation method of the far-infrared water-based carbon fiber heating wire comprises the following steps: (a) the bonding stage of forming a carbon molecule bonding layer on the surface of the precursor; (b) the homogenization stage of the thickness of the carbon molecule bonding layer; (c) The stage of carbonization of the precursor filaments forming a uniform carbon molecular bonding layer; (d) the stage of resistance measurement of the carbonized bonded filaments. The device includes nano bonding equipment, homogenizing equipment, carbonizing equipment and resistance measuring equipment. By adopting the preparation method and device, the surface of the raw silk is evenly bonded by the water-based conductive coating, and a heating wire with high thermoelectric conductivity and balanced resistance value can be produced, and when the production is temporarily interrupted, the rigidity of the bonding layer is slow, Quality management is simple.

Description

Technical field [0001] The invention belongs to the technical field of far-infrared electric heating, and specifically relates to a method and device for preparing a far-infrared water-based carbon fiber heating wire that is uniformly bonded on the surface without being lumpy. Background technique [0002] Generally speaking, the electric heating film is a heating element in the shape of a thin pad built-in board that relies on electric current to generate heat. It has the advantages of simple temperature adjustment, no air pollution, very hygienic and no noise. Therefore, it is widely used in heating pads, heating stickers, mattresses, insulation quilts, insulation blankets, residential heating facilities in communities and general houses, etc. It can also be used in heating facilities, construction sites, or commercial buildings such as offices or shops. Heating facilities for industrial construction such as camps, agricultural equipment such as plastic greenhouses or agricultu...

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.
