Embodiment Construction

[0018] The technical content of the present invention will be further described in detail below in conjunction with specific embodiments.

[0019] A series-type constant power electric heating belt processing technology provided in this embodiment includes the following steps:

[0020] Step 1. Weave and wrap a layer of glass fiber braid evenly on the outer layer of the alloy heating wire core, evenly arrange a layer of inorganic lubricating powder on the surface of the glass fiber braid, and then use extrusion tube extrusion die to squeeze out the glass fiber braid Wrap a layer of busbar insulation layer, and evenly apply a layer of silicone oil on the outside of the busbar insulation layer, and then put the busbar insulation layer into the cooling water tank and immerse it in water for cooling after cooling in the air. The silicone oil on the surface is scraped off and recycled to produce a constant power heating busbar; the alloy heating wire core is made of copper-nickel al...

Abstract

The invention discloses a tandem type constant power ribbon heater processing technology. The technology includes the following steps: 1. wrapping a glass fiber braid ply on the outside of an alloy heating core, arranging one layer of inorganic lubrication powder, extruding one layer of busbar insulating layer, coating a silicone oil, cooling the alloy heating core in the air and immersing the alloy heating core in water for performing cooling, scraping the silicone oil on the surface of the busbar insulating layer and recycling the silicone oil, and obtaining the constant power heating busbar; 2. coating one layer of heat conductive silica gel on the surface of the constant power heating busbar, such that the silica gel fills the gaps between each constant power heating busbar in a heating busbar group, curing the heat conductive silica gel which is filled in the heating busbar group; 3. adopting an extruding pipe extrusion die to extrude one layer of total insulating layer on the outside of the heating busbar which is processed by the step 2, then coating one layer silica oil on the outside of the total insulating layer, cooling the total insulating layer in the air and immersing the total insulating layer in water for performing cooling, taking the total insulating layer from a cooling water tank, scraping the silica oil on the surface of the total insulating layer and recycling the silica oil.

Description

technical field [0001] The invention relates to the technical field of constant-power electric heating belt processing, in particular to a series-type constant-power electric heating belt processing technology. Background technique [0002] Electric heating cables are a new type of high-tech product. Since they entered the application field in the 1970s, they can be widely used in the transportation of liquid objects in pipelines and the antifreeze and heat preservation of tanks, maintaining process temperature, heating roads, and ramps. , Crosswalks, eaves and floors, etc. When the electric heating cable is working, when heating a certain system, if the heat transferred by the electric heating cable to the system per unit time is equal to the heat transferred from the system to the external environment, the temperature of the system remains unchanged. The highest temperature that the system can reach is called the highest maintenance temperature. [0003] The power output...
