Description
Technical field
The composition that the invention belongs to material is the electrical heating element of feature.
Background technology
The electrothermal semiconductor membrane technique is a kind of electric-heating technology, and this technology all use temperatures in fields such as industry, agricultural, military affairs, household electrical appliances can be extensive use of under the working conditions below 500 ℃, and it can adopt various heat forms such as tabular, tubulose.The electrothermal semiconductor membrane technique, states such as America and Europe, Japan just carry out theoretical investigation to it from the forties, but do not occur the more sophisticated electrothermic film element that can really be applied to some products as yet so far.Domesticly begin to have occurred one by one a collection of patent and element about electrothermal film technology from late nineteen eighties, but because the not science of the imperfection of prescription and manufacture craft all exists power instability, decrement big (more than 30%), the little problems such as (in 240 ℃) of operating temperature range.So the sophisticated product of none appears on the market so far in application process, also be short-lived even there is the discrete product to come into the market reluctantly, in very short time, just died young because of quality problems.
The common electric heating material of people all is the metallic resistance silk, and it is to adopt to change its sectional area and coiling length change resistance value, thereby reaches power requirement.Power loss is big during metallic resistance silk energising work, and usually consistent when being recognized that the resistance wire heating work, its electric energy converts the heat energy conversion rate to and is no more than 56%, so the power of resistance heater is all very big, takes.The metallic resistance silk generally has visible light when energising work, therefore as its easy oxidation of electrical heating element, the life-span is short, and the power attenuation that works long hours is big, and naked light is arranged, and is dangerous.Therefore can not use in many places.On many environment that do not allow static (inductive current) and product, can not adopt the metallic resistance silk as thermo electric material in addition.
The semi-conductor PTC thermo electric material that begins to use from the eighties, it has overcome the deficiency of many wire materials, but the cost of manufacture height of ptc material, starting current is big during work, and working temperature can only reach the highest 280 ℃ (PTC Curie-point temperature), therefore is subjected to great restriction on using.
Summary of the invention
The purpose of this invention is to provide that a kind of thermal energy conversion rate height, decrement are little, the flames of anger, the life-span is long, cost of manufacture is low electrothermal semiconductor membrane technique.
The object of the present invention is achieved like this:
A kind of saturated solution that is used to prepare semiconductor thermoelectric film, its composition is by weight percentage: tin tetrachloride 47-60, hydrofluoric acid 5-15, boric acid 0.1-1, titanium tetrachloride 0.1-2, Repone K 1-4, four nickelous chloride 2-8, butter of antimony 2-8, surplus is a dehydrated alcohol.
A kind of working method of semiconductor thermoelectric film is characterized in that (1) with the solution for preparing, its component content of saturated solution, and weight percent:
Tin tetrachloride 47-60, dehydrated alcohol 28-48, hydrofluoric acid 5-15, boric acid 0.1-1, titanium tetrachloride 0.1-2, Repone K 1-4, nickel superoxide 2-8, butter of antimony 2-8.
This solution concussion is stirred and was become saturated solution in 8 hours.
(2) select the insulation strength height, device substrate high temperature resistant more than 1000 ℃, anti-violent change cleans, dries.
(3) base material is heated to 700 ℃, use the saturated solution for preparing to form sediment stain, look its surperficial power difference and decision solution shallow lake stain thickness 1 μ m-6 μ m at the required heating surface of element.
(4) 700 ℃ of holding element temperature are 30 minutes; Allow its naturally cooling then.
(5) according to the purposes and the using method of electrical heating element, adopt series, parallel or string and bonded method to coat high temperature resistant electrode more than 800 ℃ at the rete electrode position, carry out 500-600 ℃/30 minutes burin-in process then.
(6) carry out the energising burin-in process of this electrical heating element 1.5 hours according to the working temperature of the actual use of this electrical heating element and operating voltage+17%.
Advantage of the present invention and positively effect:
Product of the present invention is a kind of thick only semiconductor film of several microns as a kind of novel electric heating material, closely be combined into one and become electrical heating element through processing treatment and carrier, it is an a kind of electric heat source in case energising, and electrothermal calefactive rate is fast, than common electrical hot material fast again more than; Electric energy converts heat energy efficiency to up to more than 93%, economizes on electricity more than 35% than common electrical hot material; Product of the present invention is a kind of neutral thermal source, and the flames of anger is therefore very safe; Can be suitable for various power supply forms (AC and DC all can) and voltage range (6V-380V); Do not exist oxidation can not be subjected to the influence of other various abominable gases during work yet, so long service life, general at more than two times of common electrical hot material; Product working stability of the present invention, decrement is little, generally can be controlled in 5%; Cost of manufacture is low, installs simply, and is strong with the supporting adaptability of product; Starting current is little, maintains an equal level basically with running current; In a word, product of the present invention has overcome the shortcoming of thermo electric material commonly used, and also overcome simultaneously the deadly defect that existing electrothermal film technology can not popularization and application, and developed their common advantage, be a kind of electric heating material of comparatively ideal easy popularization and application.
