specific Embodiment 1
[0013] A method for preparing a glass phase in a resistance paste, comprising 30 parts by weight of silicon dioxide, 20 bismuth trioxide, 15 zinc oxide, 10 zirconium dioxide, and 10 boron oxide. The specific preparation steps are:
[0014] (1) Put silicon dioxide, bismuth trioxide, zinc oxide, zirconium dioxide and boron oxide into a three-dimensional swing mixer and mix for 3 times, each time for 30 minutes;
[0015] (2) Put the mixture in step (1) into a crucible, put it into an electric melting furnace for melting, set the melting temperature to 1300°C, take it out immediately after continuous melting for 3 hours, put it into water for water quenching;
[0016] (3) The mixture after water quenching in step (2) is preliminarily crushed with an impact crusher, and then placed in a pulverizer for secondary crushing, and then put into an air blowing flotation machine to remove impurities , and then put it into a ball mill and add water of the quality of the mixture to carry out...
specific Embodiment 2
[0019] A method for preparing a glass phase in a resistance paste, comprising 40 parts by weight of silicon dioxide, 30 bismuth trioxide, 20 zinc oxide, 15 zirconium dioxide and 15 boron oxide. The specific preparation steps are:
[0020] (1) Put silicon dioxide, bismuth trioxide, zinc oxide, zirconium dioxide and boron oxide into a three-dimensional swing mixer and mix for 5 times, 40 minutes each time;
[0021] (2) Put the mixture in step (1) into a crucible, put it into an electric melting furnace for melting, set the melting temperature at 1500°C, take it out immediately after continuous melting for 4 hours, put it into water for water quenching;
[0022] (3) The mixture after water quenching in step (2) is preliminarily crushed with an impact crusher, and then placed in a pulverizer for secondary crushing, and then put into an air blowing flotation machine to remove impurities , and then put it into a ball mill and add water of the quality of the mixture to carry out ball...
specific Embodiment 3
[0025] A method for preparing a glass phase in a resistance paste, comprising 35 parts by weight of silicon dioxide, 25 bismuth trioxide, 18 zinc oxide, 13 zirconium dioxide, and 13 boron oxide. The specific preparation steps are:
[0026] (1) Put silicon dioxide, bismuth trioxide, zinc oxide, zirconium dioxide, and boron oxide into a three-dimensional swing mixer and mix 4 times, each time for 35 minutes;
[0027] (2) Put the mixture in step (1) into a crucible, put it into an electric melting furnace for melting, set the melting temperature at 1400°C, take it out immediately after continuous melting for 3.5 hours, put it into water for water quenching;
[0028] (3) The mixture after water quenching in step (2) is preliminarily crushed with an impact crusher, and then placed in a pulverizer for secondary crushing, and then put into an air blowing flotation machine to remove impurities , and then put into a ball mill and add water of the quality of the mixture to carry out bal...
