Abstract

The invention discloses a self-regulating polymer heating tape, which comprises two heating conducting wires arranged in parallel. PTC material layers are evenly extruded on the heating conducting wires, and are prepared by 82 parts of high-pressure low-density polyethylene, 9 parts of hexyne carbon black, 8 parts of zirconia and 1 part of trimethylolpropane trimethacrylate; the PTC layer is coated with an insulating layer which is coated with a shielding layer; and the shielding layer is provided with a sheath. The self-regulating polymer heating tape has the characteristics of low starting current, high tracing temperature, stable performance, electrical energy conservation, and convenient installation and maintenance.

Description

technical field [0001] The invention relates to a self-controlling temperature heating cable, in particular to a polymer self-controlling temperature heating belt. Background technique [0002] Polymer self-controlling temperature heating cables first appeared in the United States in the early 1980s. At that time, they were mainly used in the petroleum and petrochemical industry. The purpose of condensing and reducing the main force of transportation. At that time, the world was undergoing a stage of continuous change in the petrochemical industry. New technologies and new products are constantly being applied, and have been widely used in many fields. For example, in industry, they are mainly used in petroleum, chemical, thermal power plants and other places where it is necessary to prevent the liquid substances in pipelines or tanks from solidifying / slow flow, and in public facilities. On the one hand, it is mainly used for heat tracing of fire-fighting pipelines, and on...
