Abstract
The present invention relates to a silicate-based directly-heated infrared radiation electric heating body and its preparation method. It is characterized by that the core portion of which is a black electric heating glaze applied between silicate base body and surface glaze layer. The key steps of its preparation method are: preparing electric heating glaze slip; coating and medium roasting; preparing surface glaze slip and silver slurry; glazing and firing at low-temp.. Said invented electric heating body possesses the advantages of extensive application, high thermal inertia efficiency, long service life and simple production process.
Description
The present invention relates to silicate-base direct-heating type infrared radiation electric-heating body and preparation method thereof, it belongs to the composition character of material is the Ohmic resistance heating part class of feature.
The ceramic base thermo electric material of extensive use at present has only the PTC pottery a kind of.The defective of PTC pottery is that working temperature is low, power attenuation is big, high voltage withstanding, big current capacity is poor, and manufacturing cost is also higher.
Purpose of the present invention is to provide a kind of brand-new silicate-base thermo electric material to society, and it is provided with those defectives of above-mentioned PTC pottery, and use is also extremely convenient.
Silicate-base direct-heating type infrared radiation electric-heating body can describe according to accompanying drawing.As shown in the figure, it contains silicates basal body 1 and surface glaze layer 3, and between described silicates basal body 1 and surface glaze layer 3, also is provided with one deck electric heating glaze 2, simultaneously at the two ends of electric heating glaze 2, is provided with a pair of silver electrode 4 that electrically contacts with described electric heating glaze 2 maintenances.
The manufacture method of silicate-base direct-heating type infrared radiation electric-heating body comprises following step successively: A) make the silicates basal body blank; B) get element or two do not have be inorganic compound N type semiconductor material 15～50 weight portions, leaded and titanium composition silicate glass 45～80 weight portions, add as black-envelope clay 1～5 weight portion of suspending agent with as white kaolin 1～5 weight portion of adhesive agent, after grinding, add water modulation system, evenly be coated on the above-mentioned silicates basal body blank and remove unnecessary glaze; C) in reducing atmosphere, under 800～1200 ℃, carried out medium temperature roast 10～60 minutes; D) get low temperature composition silicate glass 70～85 weight portions, inorganic color 5～15 weight portions and suspending agent, adhesive agent equivalent totally 2～10 weight portions, grind water transfer and be made into slurry coating on the product of medium temperature roast, remove unnecessary glaze, pay special attention to reserve the room of desiring to add silver electrode; E) by following prescription system silver slurry---chemical pure silver oxide 60～80% (percentage by weight, down with), heavy metallic oxide flux 2～8%, rosin 3～6%, levelling agent 15～30% are coated in D with the silver slurry) position of leaving a blank in the step; F) under 500～800 ℃, carried out low-temperature bake 5～30 minutes; G) electric-examination classification.
Silicates basal body of the present invention comprises porcelain, high-temperature tubring and glass.
Electric heating glaze of the present invention is a kind of black glaze layer from appearance.Electric heating glaze before burning till is nonconducting, in the medium temperature roast process, the fusion again of glass particle in the raw material, air between the particle almost gets the gate entirely, glass substance forms new semiconductor substance with semiconductor grain surface corrode simultaneously, add original semiconductor grain that is free state and also draw close and form conductive chain mutually, so just constituted micronetwork formula electric channel in the glaze body.Use the meaning of a large amount of composition silicate glass also to be in the prescription: when they again after the fusion, can stick on the silicates basal body securely, and batching its thermal coefficient of expansion in season and basis material mate finely; Why wherein want leaded and titanium, yes in order to produce satisfactory infrared radiation.
Based on the present invention, can make electric heating appliance miscellaneous, as porcelain electric cup, electric food warmer, electric kettle, multipurpose cooker etc.; With regard to electric heating element itself, both can be tabular, can be tubulose also, or even have parabola or hyperboloid shape.
The second largest advantage of electric heating element of the present invention is to make the multiple automobile-used electric heating appliance that is applicable to 12 volts, 24 volts, 36 volts powers of alterating and direct current; With it is that the basis can also design and manufacture the ultra-thin shape instant heating streaming electric heater that continues, and its heat efficiency can be up to 98%.
Other advantages of electric heating element of the present invention also have: also invalid the penetrating property of no any pollution in the use meets the high standard hygienic requirements; Use not oxidation for a long time, do not peel off, do not rupture, power stability, thermal inertia is extremely low, and the life-span is long especially and the heat efficiency is very high, generally than existing state-of-the-art electric heating element economize on electricity 15～30%; Production technology is simple, and cost of manufacture is lower.
