Description
Technical field
The present invention relates to a kind of electric-heating belt product technical field, particularly a kind of fire-fighting special temperature selflimiting electric tracing band.
Background technology
Electric-heating belt is a kind of novel high-tech product, since its eighties of last century enters application the seventies, and self-limited type
Electric-heating belt has become as electric-heating belt type the most general in the world today.They can be widely applied to liquid object and exist
Conveying and the anti-freezing and heat-insulating of tank body, maintenance technological temperature, heating highway, ramp, crossing, eaves and floor etc. in pipeline.
Inside self-limited type electric-heating belt, it is dispersed with the PTC macromolecular material of heat effect between two conductive core, by high score outside it
Sub-sheath, metallic shield net and macromolecule oversheath are constituted.When the power is turned on, internal PTC macromolecular material expanded by heating,
Resistance becomes big, reduces heating power, makes temperature reduce；When the temperature decreases, internal PTC macromolecular material contract on cooling, resistance
Diminish, increase heating power, make temperature increase, thus reach to be automatically adjusted the effect of temperature.
Under rated operational voltage, when ambient temperature is 0 DEG C, the instantaneous maximum current that temperature selflimiting electric tracing band starts, it is referred to as
For starting current, unit A/m represents.Starting current is one important technology index of temperature selflimiting electric tracing band, by electric-heating belt
The formula of PTC macromolecular material is determined.Under identical power situation, the size of its numerical value directly represent self limiting temperature electricity companion
The good and bad height with security performance of the electrical property in the torrid zone.When electric-heating belt works, a certain system of heat tracing, if electricity in the unit interval
The heat that the heat that heating tape transmits to system transmits to external environment equal to system, then the temperature of system keeps constant.Body can be made
The maximum temperature that system reaches, is referred to as high maintenance temperature.High maintenance temperature is to judge whether electric-heating belt can reach work temperature
The major criterion that degree requires, has the formula of the PTC macromolecular material of electric-heating belt to be determined.Control to high maintenance temperature,
Hold it in a certain specific temperature, for specific environment situation, it is desirable to heat tracing temperature reaches the building ring of assigned temperature
, there is the biggest Practical significance in border.
Along with the understanding to this novel heat tracing mode of temperature selflimiting electric tracing band, its range of application the most progressively expands, except
Outside industrial circle uses, commercial building field the most progressively uses.Therefore under new occasion, new problem is occurred in that again, as business
Industry building field fire protection pipeline heat tracing effect temperature selflimiting electric tracing band, owing to using the formula of the eighties of last century nineties, produces
Product exist that starting current is big, the life-span is low, poor safety performance, distribution facility requires the defects such as power output is big, is therefore badly in need of opening
Send out a kind of fire-fighting specialty temperature selflimiting electric tracing band.
