Abstract
The invention discloses a ribbon heater specially for snow melting and deicing, which comprises a wire core adopting high-conductivity tin-plating round copper wire. The wire core is sequentially coated with a PTC heating material, a crosslinked polyethylene insulation, a high-strength wire braid layer, and a high-density polyethylene insulation outer sheath. According to the high-density sheath material extruded after being processed by the method of the invention, the extension change rate before and after aging is within 5% which is far lower than national standard 20%;according to a product normal thermal stability test, after 2000 times of alternated cooling and heating (the highest national standard is 600 times), the heating power is no lower than 95% of rated power, the test proves that energy consumption and energy release of the product are relatively stable, function defects of material attenuation and poor thermal stability are solved, and more than 10% of energy consumption can be saved all the year.
Description
Technical field
The present invention relates to a kind of ribbon heater, specifically a kind of deicing or snow melting Special electric torrid zone.
Background technology
Along with winter, weather was severe all the more in recent years, the northern area of China takes place frequently snow disaster, ice damage, a large amount of houses, due to the accumulated snow on roof, when irradiation or the temperature rising of sunlight, the ice and snow melted is after the eaves gutter of eaves flows to drainage pipe, under low-temperature condition, may again to freeze blocking, can damage drainage pipe on the one hand, a large amount of accumulated snow can cause great threat to building structure on roof on the other hand, the personnel that very easily cause injure, civilian, agricultural installations in this case, be faced with the danger collapsed under pressure, personnel's property safety is subject to great threat, traditional sweeps away snow, take off the measures such as snow cannot address this problem.
Summary of the invention
The object of the present invention is to provide a kind of deicing or snow melting Special electric torrid zone, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
1, a kind of deicing or snow melting Special electric torrid zone, comprise the core adopting high connductivity tin-plating round copper wire, core outside is coated with PTC exothermic material, crosslinked polyetylene insulated, high duty metal silk braid, high density polyethylene (HDPE) insulating outer protective cover successively; The material prescription of described crosslinked polyetylene insulated and high density polyethylene (HDPE) insulating outer protective cover, the component of percentage is by weight: high density polyethylene (HDPE) 99.35%, tribasic lead sulfate 0.12%, lead silicate 0.05%, antioxidant 0.1%, light stabilizer 0.13%, fire retardant 0.1%, the soft stabilizing material of high-performance account for 0.25%; By improving the oversheath formula of product, product can be directly exposed in the middle of air under sunlight exposure and sleety weather use, product decay is little, can repeat throughout the year, after heat stability testing, after 2000 cold cycling replace, its heating power still remains on more than 95% of rated power; Because product stability is high, like product energy-conservation 10% can be reached.
As the further scheme of the present invention: described antioxidant is styrol benzene enzyme.
As the present invention's further scheme: described light stabilizer is that salicylic acid is to tert-butyl benzene fat.
As the present invention's further scheme: described fire retardant is tribromphenol.
As the present invention's further scheme: described tribasic lead sulfate and lead silicate form heat stabilizer.
Compared with prior art, the invention has the beneficial effects as follows: through the present invention newly fill a prescription processing extrude after high density sheath material, the extension rate of change of its aging front and back within 5%, well below 20% of national standard, after the normality heat stabilization test of product can cold and heat succeed each other at 2000 times, (national standard is the highest 600 times) heating power is not less than 95% of rated power, test proves the energy consumption release quite stable of product, solve the functional defect of material attenuate and poor heat stability, can effective energy efficient more than 10% throughout the year, of the present invention succeeding in developing reaches advanced international level, than the deicing or snow melting mode adopting original electric tracer heating system and other heating systems, save and use and installation cost more than 15%, its working service is convenient, can use throughout the year, maximum effective service life was more than 10 years, can effectively ensure civilian, the gutter of industrial building, roof drainage system is effective draining row pressure under the adverse circumstances of-40 degrees Celsius to 40 degrees Celsius, the crushing by snow load alleviating building significantly improves service life and the fail safe of building, the extent of damage at utmost to people's lives and properties under reduction bad weather circumstances.
This product has filled up product blank inside the province simultaneously, can substitute imported product of the same type, realize production domesticization to greatest extent, for the electric tracer heating system of China adds wonderful work again.To be formed in north of China market and extensively promote and use, imported material expense will be saved more than ten million yuan.
Embodiment
Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In the embodiment of the present invention, a kind of deicing or snow melting Special electric torrid zone, comprise the core adopting high connductivity tin-plating round copper wire, core outside is coated with PTC exothermic material, crosslinked polyetylene insulated, high duty metal silk braid, high density polyethylene (HDPE) insulating outer protective cover successively; The material prescription of described crosslinked polyetylene insulated and high density polyethylene (HDPE) insulating outer protective cover, the component of percentage is by weight: high density polyethylene (HDPE) (HDPE) 99.35%, tribasic lead sulfate (3PbO-PbSO4-H2O) 0.12%, lead silicate (PbSiO3) 0.05%, antioxidant 0.1%, light stabilizer 0.13%, fire retardant 0.1%, the soft stabilizing material of high-performance account for 0.25%; By improving the oversheath formula of product, product can be directly exposed in the middle of air under sunlight exposure and sleety weather use, product decay is little, can repeat throughout the year, after heat stability testing, after 2000 cold cycling replace, its heating power still remains on more than 95% of rated power; Because product stability is high, like product energy-conservation 10% can be reached.
Described antioxidant is styrol benzene enzyme, described light stabilizer be salicylic acid to tert-butyl benzene fat, described fire retardant is tribromphenol, and described tribasic lead sulfate and lead silicate form heat stabilizer.
By contrasting extension rate of change and the change rate of strength of aging front and back, high density sheath material after processing of newly filling a prescription is extruded, the extension rate of change of its aging front and back is within 5%, well below 20% of national standard, in the light aging and oxidation of antagonism outdoor, there is obvious advantage, improve the useful life of the electric-heating belt of outdoor application greatly.
This Project Product, in the use of inner ptc material, have also been made improvement, on original production technology basis, can add a small amount of manganese element and boron element, and product is improved significantly in the stability of heating.
