Description
The present invention relates to the electrothermal film technology field, particularly relevant with rare earth doped tin ash Electric radiant Heating Film.
For extremely, in the electrothermal film technology field, four kinds of electric heating film bodies are arranged generally: (one) paint-type electric heating film so far; (2) titanium nitride electrothermal film; (3) conducting polymer composite material; (4) doped-semiconductor electrothermal film.Described these four kinds of Electric radiant Heating Film all have its defective, and are various as the paint-type electric heating film processing step, pass through processes such as batching → batch mixing → roasting (1300 ℃) → pulverizing → ball milling → sieve.And lead tolerance height in the coating materials.Resistance to wear is also poor, can wipe with hand.Titanium nitride type Electric radiant Heating Film generally is magnetic control sputtering plating or hallow cathode deposition, HCD technology, the equipment complexity, involve great expense, doped-semiconductor electrothermal film (as CN88108194) is although chemical stability increases, but can't reach certain specific (special) requirements, there are its limitation in the thermal stability of this Electric radiant Heating Film and life-span in addition.
In view of this, the inventor has invented the Electric radiant Heating Film and the manufacture craft thereof that are mixed with trace rare-earth through some tests, is purpose of the present invention.
Rare earth doped Electric radiant Heating Film of the present invention is the transparent tin ash Electric radiant Heating Film that is mixed with trace rare-earth.
Rare earth doped Electric radiant Heating Film of the present invention is that the spray pyrolysis depositing operation by spraying filming liquid generates layer oxide film on the heating element surface.These elements can be enamel, pottery, and mica, glass etc. need calandria.
