Description
Technical field
The utility model is related to the technical field of the construction of cable, particularly a kind of corrosion-and high-temp-resistant long-life heating electricity
Cable.
Background technology
Heating cable is typically layed under floor, heat energy is converted electrical energy into after energization, by terrestrial surface radiation form to room
Interior heating, with the outstanding advantages such as health, energy-conserving and environment-protective, easy to control, human body sensory be comfortable, therefore has obtained widely should
With.Heating cable is using special alloy heating wire as operation element, using the principle completion work of resistance heating.Due to it
Typically it is layed under indoor floor, so its reliability and security are particularly significant.
General heating cable, on the premise of Specification Design, manufacture, installation and use, its heater and insulator portion
Operating temperature it is general at 80 DEG C or so, and the operating temperature ratings of insulating barrier are general more than 90 DEG C, the specified work of heater
Make temperature general more than 200 DEG C, so heating cable can run steadily in the long term under normal circumstances.At present, on the market
Heating cable producer typically can all provide heating power from several hectowatts to several kilowatts, 10 ~ 30 kinds of heating cables of different size.
In the design of cable, considered based on factors such as physical dimension, weight, easy construction degree, costs, low power heating cable one
As with the high-resistance electrothermic alloy such as ferrum-chromium-aluminum, nickel chromium triangle, nickel chromium iron, powerful heating cable it is general with resistivity than relatively low copper
Nickel alloy.The advantage of corronil is low resistivity, in the case of equal length and heating power, relative to high-resistance alloy
For, can accomplish that volume is smaller, lightweight, soft, low cost, it is readily transported and constructs.But shortcoming is also apparent from, because
Copper is a kind of active metal of comparing, so the corrosion resistance of corronil, antioxygenic property, resistance to elevated temperatures are all poor, and
With the rising of temperature in use, its oxidation and the speed that is corroded can greatly speed up.
Used as indoor heating product, facing to thousands upon thousands setters and user, this just runs into heating cable unavoidably
Installation lack of standardization and situation about using.Used inferior materials and turned out substandard goods when such as installing, with underproof auxiliary material, the big material of covering thermal resistance, no
Standard construction etc., it is lack of standardization when also user uses to use, such as the ground of heating cable of having mated formation is covered with the big thing of thermal resistance
Face etc., can so cause the heat for heating cable to come out well, and it is invariable power heating to heat cable, is entered
One step causes internal heat constantly to be accumulated, temperature more and more higher, and the temperature of heater and insulation tends to exceed 90 DEG C even 200
More than DEG C.So there will be two kinds of situations, and the first situation is：The corronil heater of high-power heating cable is in residual oxygen
In the presence of gas and insulating materials decomposition precipitate at high temperature, its oxidation and corrosion rate greatly speed up, and cause it to generate heat
Power is constantly reduced, or even can develop into the situation appearance for being broken heating wire and causing system to be scrapped, and substantially reduces electric ground
In the life-span of heating system, very big trouble is all brought to user and producer.Second situation be：Insulating barrier is long-term specified more than its
Worked under maximum operation (service) temperature, degraded, cleacvage reaction can progressively occur, finally cause insulation damages.In addition, plastic insulation layer
High temperature degradation product, it is also possible to corrode the Exothermal Alloys of some poor corrosion resistances, causes heating wire resistance to incrementally increase, or even
Fracture.
So, high-power the corrosion-resistant, anti-oxidant of heating cable corronil, resistance to elevated temperatures how are improved, can
Enough special screnes for widely adapting to some installations lack of standardization and using, so as to realize remaining able under severe conditions steady for a long time
The purpose of fixed work, as a difficult problem of the pendulum in face of heating cables manufacturing producer.

Life.（4）The utility model replaces polyvinyl chloride as sheath material with flame-proof cross-linking polyolefine material.Heating cable one in the past
As all using polyvinyl chloride as restrictive coating, the maximum operating temperature of polyvinyl chloride is usually no more than 90 DEG C, more than highest work temperature
Degree polyvinyl chloride can soften, and generally more than 150 DEG C degree will melt, so as to lose the protective effect to cable.And it is poly-
Vinyl chloride contains halogen element, is non-environmental protection material.And after fire retardant polyolefin is crosslinked, molecule reticulates knot by linear structure change
Structure, becomes a kind of and does not melt the material not melted by fusible material, and its heat resistance and mechanical performance are substantially improved, improper
At a high temperature of melting phenomenon will not also occur, so as to heating cable play a very good protection.And flame-proof cross-linking polyene
Hydrocarbon is a kind of environment-friendly materials, is particularly suitable for Indoor environment and uses.
