Cobalt chloride and magnesium chloride, stir evenly, and stand, obtain electrothermal conversion body coating solution；
Electric heating conversion coating is made in electric heating conversion coating liquid prepared by examples detailed above, and forms electric heating conversion heat generating member,
The insulating materials of selection is microcrystal glass plate, can choose following three kinds of modes (the data employing mode b. in table 2):
(1) after the one side of the microcrystal glass plate of a. long 400mm, width 150mm, thickness 4mm carries out blasting treatment, 805 DEG C are put into
High temperature ovens in baking 15 minutes；
B. after the one side of the microcrystal glass plate of long 400mm, width 150mm, thickness 4mm carries out blasting treatment, it is put into 750 DEG C of height
Baking 15 minutes in warm oven；
(2) after the one side of the microcrystal glass plate of a. long 400mm, width 150mm, thickness 4mm carries out blasting treatment, 825 DEG C are put into
High temperature ovens in baking 14 minutes；
B. after the one side of the microcrystal glass plate of long 400mm, width 150mm, thickness 4mm carries out blasting treatment, it is put into 775 DEG C of height
Baking 14 minutes in warm oven；
(3) after the one side of the microcrystal glass plate of a. long 400mm, width 150mm, thickness 4mm carries out blasting treatment, 850 DEG C are put into
High temperature ovens in baking 12 minutes；
B. after the one side of the microcrystal glass plate of long 400mm, width 150mm, thickness 4mm carries out blasting treatment, it is put into 800 DEG C of height
Baking 12 minutes in warm oven；
(2) by microcrystal glass plate (such as above-mentioned b obtain) taking-up after high-temperature baking, rapidly by electric heating conversion coating liquid
Thermal jet is coated onto microcrystal glass plate and did on the face of blasting treatment, by the electrothermal conversion body clad plate alcohol washes after natural cooling
Afterwards, the silver paste line that a 10mm wide is respectively brushed in devitrified glass electrothermal conversion body coating board ends places into 120-150 DEG C low
Baking 20 minutes in warm oven；
(3) microcrystal glass plate is put into rapidly again 805 DEG C (corresponding aforesaid way a), 825 DEG C (corresponding aforesaid way b),
850 DEG C (baking 15 minutes in the high temperature ovens of corresponding aforesaid way c), is placed on normal temperature environment cooling, obtains crystallite after taking-up
Glass heating panel.
In this example, the electric heating conversion coating liquid being typically formulated interior spraying within three hours is finished.
So far, electric hot plate completes.As long as the upper surface of two silver wires are separately connected two poles, heating board when use
It can work.
Under identical testing conditions, the thermometric of triumph is respectively adopted in electric heating conversion coating made from 1 Examples 1 to 4 of table
Instrument and distant place power instrument test its maximum operating temperature and changed power.When it is temperature-resistant so that power is become larger when electric conversion efficiency
It is lower, when changed power is not in direct ratio with temperature, electric conversion efficiency is lower.Maximum operating temperature refers to exist in its work
Power stability works when maximum temperature.Maximum operating temperature, electric conversion efficiency, service life are as shown in table 2.
Table 2 (uses aforesaid way b)
| Embodiment | Maximum operating temperature | Electric conversion efficiency | Service life |
| 1 | 700 degree | 60% | 10000 hours |
| 2 | 680 degree | 82% | 15000 hours |
| 3 | 650 degree | 88% | 20000 hours |
| 4 | 605 degree | 96%-98% | 25000 hours |
| Comparative example | Maximum operating temperature | Electric conversion efficiency | Service life |
| 1 | 600 degree | 50% | 1000 hours |
| 2 | 580 degree | 80% | 3000 hours |
| 3 | 550 degree | 85% | 5000 hours |
| 4 | 500 degree | 90-95% | 9000 hours |
Contrast on effect is as it can be seen that integral material heatproof is in 805-850 degree in preparation process of the invention, by chlorination is such as added
Copper, silver chlorate, iron chloride, cobalt chloride, Nickel dichloride hexahydrate, anhydrous stannic chloride synergistic effect so that finally obtained electric heating turn
The maximum operating temperature for changing coating adstante febre can be up to 700 degree, since operating temperature can be higher, so that heating speed is also very fast.
In the distance under power instrument test when electrothermal conversion body coating duty is close at 605 degree, since graphene, graphite powder, three is added
The synergistic effect of antimony chloride is so that power increases with temperature and stablized, so usually electric conversion efficiency is in 96%-98%.Work as electricity
Close at 605 degree, power increases with temperature and stablizes heat exchange body coating duty, since aluminium chloride, lithium chloride, chlorination is added
Magnesium, gas-phase silica sufficiently merge that the service life is longer and stablizes with devitrified glass, usually at 25000 hours or more；Using model
It encloses wide.
This example sprays to the dosage of the coating slurry on insulating body surface as follows and parameter is calculated；
A. for making the electrothermal conversion body of heating liquid with 8-10w/cm2(power coefficient g1), every watt of 0.02-0.05g
The dosage of (dose factor a1) sprays；
B. for making the electrothermal conversion body of heating air with 2.5-4w/cm2(power coefficient g2), every watt of 0.02-0.04g
The dosage of (dose factor a2) sprays.
Use example 1:
Rapid water heater quartz electrothermal tube, outer dimension；Diameter 45mm overall length 600mm heats liquid according to production
Body is in electrothermal conversion body calculation method, the machinable maximum power of the size members:
W=S*g1 (S- surface area)
That is (3.14*2.25*2.25*50) * 10=7948w
Need to be sprayed on dosage L=W*a1 i.e. 7948*0.05=397g
Then pipe fitting is removed into surface and oil contaminant with sandblasting, after cleaning, drying, be placed in heating furnace, temperature rises to 825 DEG C simultaneously
Heat preservation 10 minutes, any coating solution for calculating dosage of Example 1-4, is all sprayed on quartz components surface, later respectively
Take out natural cooling.
Component after cooling is dried in 825 DEG C of furnaces by requirement brushing silver paste production electrode, then, is solidified, it is cold
But, power supply wiring is drawn with mechanical connection manner after cooling, electrothermal conversion body completes.
Be powered test, and electrothermal conversion body is powered on energization test, after inspection, the quartzy electric heating of rapid water heater
Pipe completes.
Use example 2:
The silicon wafer electric hot plate of oven dry combustion method is made, outer dimension: 400mm*150mm, according to the electricity of production heating air
Heat exchange body calculation method, the machinable maximum power of the size members:
W=S*g2 (S- surface area)
That is (40*15) * 4=2400w
The dosage L=W*a2 i.e. 2400*0.04=96g for needing to spray
Then it by after panels sandblasting cleaning, drying, is placed in heating furnace, temperature rises to 850 DEG C and keeps the temperature 10 minutes, takes
Any coating solution for calculating dosage, is all sprayed on silicon crystal slate component surface, takes out natural cooling later in embodiment 1-4.
Component after cooling is made into electrode by requirement brushing silver paste, is then dried in 850 DEG C of furnaces, is solidified, is cold
But power supply wiring is drawn with mechanical connection manner afterwards, electrothermal conversion body completes.
Be powered test, electrothermal conversion body is powered on energization test, after inspection, far infrared silicon wafer electric hot plate has been made
At.
The foregoing is only a preferred embodiment of the present invention, not does restriction in any form to the present invention.It is all
