2～8.5W/CM
2, as reaching 18W～20W/CM as adding hot water
2About, enlarged the range of application of Electric radiant Heating Film.And Electric radiant Heating Film adapts to the expanded range of voltage from 12V～220V～380V.
Adopt production technology of the present invention and vapor phase growing apparatus, can make Electric radiant Heating Film resistance even, and the may command resistance value, easy burn-out not, the life-span is long; The tack of Electric radiant Heating Film improves greatly, does not peel off, and is unattenuated, and the life-span is long; Fully deposition saves material; Reclaim waste gas, turn waste into wealth, hydrochloric acid can be recycled, and saves cost.The electrical property and the range of application of Electric radiant Heating Film have been improved greatly.
The present invention compares with prior art,
1. profile is alternative strong:
The inorganic electric heating film is not because direct coated on matrixes such as glass, enamel, pottery, therefore is subjected to the restriction of surface configuration.But various complicated vessel or working surface be coated all.
2. heat efficiency height
Electric radiant Heating Film is that planar exothermic material and heating object form thermal conductive surface to greatest extent, thermal capacity is little, heat transfer resistance is little, when the energising heating, heat can be passed to heated object very soon, and because this mode of heating heat conductivity is good, so the electric heating element self-temperature is not high, there are not phenomenon generations such as rubescent, red-hot.The radiation heat loss is very little.Therefore the electric heater heat efficiency made from Electric radiant Heating Film is quite high, generally about 90%.And traditional heating wire is because radiating surface is little, and not tight with heating object, in the electric heating transfer process, the heat energy that electric energy produced can not be passed to heated object very soon, causes on the electric heating element heat too concentrated.It is red-hot that element itself becomes very soon, makes the very major part of electric energy become luminous energy and scatter and disappear, and causes electric conversion efficiency lower, is generally about 50%-60%.For example: two identical glass pots, one with Electric radiant Heating Film heating, and another heats with heating wire, is 300W power, heat 500 milliliters 26 ℃ cold water, the boiling water time of actual measurement, the former is 9 minutes and 16 seconds, the heat efficiency is 92%, and the latter is 20 minutes and 24 seconds, and the heat efficiency has only 42%.
And for example using electric cup and an electrothermal tube electric cup of semiconductor conducting film, equally all is the power of 300W, boils the 300ml temperature equally and be 16 ℃ water, the former only uses 6 minutes and 30 seconds just can be boiled with water, the latter but uses 11 minutes and 1 second, and the former heat efficiency is 90%, and the latter only is 54%.
3. the life-span is long
General heating wire always uses under red-hot state, so be easy to produce oxidation, cause and opens circuit.And Electric radiant Heating Film temperature when work is relatively low, as uses 100C m
2800W (the every C m of 8W
2), pottery shape Electric radiant Heating Film is made electric chafing dish, and when being in 100 ℃ of boiling water states, Electric radiant Heating Film self average film temperature has only about 160 ℃, low film working temperature like this. thoroughly solve the autoxidation problem of electrothermal film material under the energising heated condition, prolonged useful life.
On the other hand, the physicochemical properties of Electric radiant Heating Film are very stable, nesa coating for example, the anti-wear performance of itself is good, hardness is Mohs 7-8 level, the hardness that is equivalent to quartz～topaz, the friction in general the use is had no effect to film, and the fusing point of himself is more than 1000 ℃, therefore in use heat resisting temperature is very high, Heat stability is good, it is respectively at hydrochloric acid, red fuming nitric acid (RFNA), soaked 72 hours in 60% sulfuric acid and 1% NaOH, the performance no change, under 350 ℃, energising was used 3000 hours continuously, non-oxidation, the performance no change, the heating object volume is not as long as collide (falling) with sudden force, and heating element does not just have the possibility of damage, so the conducting film working life was at 3000-10000 hour.
For organic electro-thermal films, better softness can be around song, folding, and the folding quality of film is greater than 5000 times.
4. have from limitting temperature characterisitic
Most of Electric radiant Heating Film have from limitting temperature, and promptly resistance has ptc characteristics, and when the temperature of Electric radiant Heating Film raise, it is big that the resistance of Electric radiant Heating Film becomes, and this specific character is that heating wire is not available.
