Description
Technical field
The present invention relates to a kind of heater element, relate in particular to and a kind ofly heat used plastic alloy heat generating wire cable applicable to all trades and professions.
Background technology
In the prior art electric heater, the employing metal electric heating tube is more, general wires such as metal electric heating tube employing siderochrome aluminium high resistance are done heater element, and do the insulation material with magnesia powder, and use iron, copper, stainless steel, Titaniums etc. are made outer tube, therefore metal electric heating tube is a kind of rigid electric heating device, it has higher heating-up temperature, typical temperature can arrive 800 ℃～1000 ℃, so metal electric heating tube has the strong and weak characteristics of low-temperature space heating advantage of high-temperature region heating advantage, and (calorific intensity can reach 1～3KW/M) to have higher calorific intensity, therefore the unit volume heating power is big, and it is less that volume can be done.Therefore, be best suited for the high-temperature region heating.
Though metal electric heating tube has the high characteristics of calorific intensity,, the shortcoming of Cun Zaiing is in actual use:
1. belong to rigid electric heating device owing to this metal of prior art electric heating tube, not only its min. turning radius is big, just can not change shape again after the formed product, and metal processing is difficult, is not suitable for the long-distance pipe heating.
Since this metal of prior art electric heating tube owing to be subjected to heating wire poling and magnesia powder to fill out the influence of pipe, its length is difficult to do length, and is just very difficult greater than 4 meters length, therefore is not suitable for the large tracts of land heating.
3. because the structural limitations of this metal of prior art electric heating tube, electric heating tube internal heat generation silk is big with the temperature difference of the outer heating object of pipe, and the heating wire heating-up temperature can reach 800 ℃～1000 ℃, ≯ 100 ℃ low-temperature space heating occasion, it is big to add thermal inertia, so the temperature control characteristic is poor.
4. because the heating wire of this metal of prior art electric heating tube is subjected to the concentricity on the different cross section when being subjected to poling, and the concentricity during bend pipe, oxidated magnesium powder fill out pipe, being shaped adds density on the different cross section in man-hour, be subjected to the influence of the manual processing factors of staff, quality is not easy to stablize, temperature conduction in pipe is difficult for evenly, the metallic resistance filament length phase is operated in the easy oxidation etc. of working of high-temperature region more than 800 ℃, make it to cause that electric heating tube blows easily or punctures, and being not suitable for, so poor safety performance in inflammable and explosive occasion work.
5. because this metal of prior art electric heating tube adopts metal tube to do shell, and not acidproof alkali lye of metal material and chemical solvent corrosion, even adopt the titanium electric heating tube, corrosion-resistant also have a limitation, and useful life is short.
It is shown in Figure 2 to see also Fig. 1, and this is that number of patent application 02136312.9 is entitled as the structural representation of " Fluroplastic alloy heating cable ".(10) be the alloy heat generating silk, (20) be the fluoroplastic insulation layer, (21) be the fluoroplastics inner insulating layer, (22) be the fluoroplastics external insulation layer, (30) be the metal screen layer of zinc-plated or silver-gilt copper wire, so very convenient because of producing by the cable equipment automated production, quality is more reliable, but prior prehensile with electric wire.Belong to a kind of soft heating element.Go out an arteries and veins together in the present invention.
Though Fluroplastic alloy heating cable and total many identical advantages of the present invention and characteristics separately, can use at ≯ 200 ℃ low-temperature space, and the present invention can use at ≯ 100 ℃ low-temperature space, key is good and cheap, and the suitable making of maximum advantage is used for right ≯ 100 ℃ liquid and adds gentle warming heater.Suitable making is used for right ≯ 100 ℃ wet method heater, and can be used in the field that metal electric heating tube can not relate on a large scale.
