Embodiment 1
[0022] Embodiment 1, a production process of an electric heating film heating tube, comprising the following steps:
[0023] Step 1, apply white material to 100-150mm at both ends of the quartz glass tube to form whiteheads;
[0024] Step 2, prepare the electrothermal film solution, pressurize the electrothermal film solution to form a mixed mist, and spray it on the quartz glass tube in the high-temperature furnace at 700 ° C to 900 ° C by vapor deposition technology, so that the quartz glass tube is uniformly smoked and mixed with mist to form an electric heating film tube;
[0025] Step 3, configure the silver oxide solution and grind it into silver paste. After the electrothermal film tube is cleaned and dried, use the silver paste to brush the two ends of the electrothermal film tube to form silver electrodes;
[0026] Step 4, the film tube coated with silver is placed in a furnace at a high temperature of 500°C to 700°C to bake the silver electrode;
[0027] Step 5, sil...
Embodiment 2
[0034] Example 2, the steps are the same as in Example 1, wherein the weight percent of each component in the white material is: glue 3%, Portland cement 17%, talcum powder 40%, light magnesium oxide 5%, water 35%. The weight percent of each component in the electrothermal film solution is 44.5% of tin tetrachloride, 51% of alcohol, 0.7% of antimony trichloride, 0.08% of rare earth elements, 0.75% of ferric chloride, 2% of absolute ethanol, tetrachloride Titanium 0.9%, boric acid 0.07%. The weight percent of each component in the silver oxide solution is 60% of silver oxide, 5% of bismuth oxide, 15% of turpentine, 5% of lead borate, 4% of calcium borate, 10% of castor oil and 1% of rare earth element. The weight percent of each component in the high-temperature insulating gel is 25% of epoxy resin, 15% of epoxy resin insulating coating, 15% of ether-ester solvent, 6% of ketone solvent, 15% of ester solvent, and 10% of alcohol-ether solvent. %, shrinkage oil ether diluent 14%....
Embodiment 3
[0035]Embodiment 3, the steps are the same as in Embodiment 1, wherein the weight percent of each component in the white material is: glue 7%, Portland cement 10%, talcum powder 30%, light magnesium oxide 3%, water 50%. The weight percent of each component in the electrothermal film solution is 43% of tin tetrachloride, 53% of alcohol, 0.6% of antimony trichloride, 0.09% of rare earth element, 0.6% of ferric chloride, 1.95% of absolute ethanol, tetrachloride Titanium 0.7%, boric acid 0.06%. The weight percent of each component in the silver oxide solution is 40% of silver oxide, 10% of bismuth oxide, 20% of turpentine, 10% of lead borate, 3% of calcium borate, 15% of castor oil and 2% of rare earth element. High-temperature insulating gel, the weight percentage of each component is epoxy resin 30%, epoxy resin insulating coating 5%, ether-ester solvent 13%, ketone solvent 12%, ester solvent 25%, alcohol-ether solvent 5%, shrinkage oil ether diluent 10%. The glycidyl ether di...
