Embodiment 1
[0031] Example 1: Preparation and sealing of materials
[0032] According to the composition ratio of each component of Example 1 in Table 1, weigh the corresponding analytically pure raw materials (B 2 O 3 , Bi 2 O 3 , ZnO, Ce(NO 3 ) 3 ), use a planetary ball mill to ball mill for 24 hours to mix evenly; then put the powder into a platinum crucible, place it in the air atmosphere of a box-type resistance furnace, and heat it to 1000°C at 3°C / min for 1 hour; then, take out the crucible, Pour the melt into deionized water for rapid cooling, and dry to obtain fragments of glass melt; grind and pass through a 100-mesh sieve to obtain glass powder. Mix glass powder with polyvinyl alcohol, fish oil, ethanol and toluene (80%, 2%, 1%, 10%, 7% by weight) into a slurry, which is uniformly dispersed in a ball mill; cast molding, natural Dry, then cut into the embryo body of the desired shape; place the embryo body on the part to be sealed, heat up in an electric furnace at a rate of 2°C / mi...
Embodiment 2
[0033] Example 2: Preparation and sealing of materials
[0034] According to the composition ratio of each component in Example 2 in Table 1, weigh the corresponding analytically pure raw materials (B 2 O 3 , Bi 2 O 3 , ZnO, Ce(NO 3 ) 3 ), use a planetary ball mill to ball mill for 24 hours to mix evenly; then put the powder into a platinum crucible, place it in the air atmosphere of a box-type resistance furnace, and heat it to 980°C at 3°C / min for 1 hour; then, take out the crucible, Pour the melt into deionized water for rapid cooling, and dry to obtain fragments of glass melt; grind and pass through a 100-mesh sieve to obtain glass powder. Mix the glass powder with methyl cellulose, polyvinyl alcohol, n-butanol and acetone (weight ratios are 82%, 2%, 2%, 8%, 6%) to form a slurry, which is uniformly dispersed in a ball mill; Prolong the forming, dry naturally, and then cut the embryo body into the desired shape; place the embryo body on the part to be sealed, heat it up in an ...
Embodiment 3
[0035] Example 3: Preparation and sealing of materials
[0036] According to the composition ratio of each component in Example 3 in Table 1, weigh the corresponding analytically pure raw materials (B 2 O 3 , Bi 2 O 3 , ZnO, Ce(NO 3 ) 3 ), use a planetary ball mill to ball mill for 24 hours to mix evenly; then put the powder into a platinum crucible, place it in the air atmosphere of a box-type resistance furnace, and heat it to 960°C at 3°C / min for 1 hour; then, take out the crucible, Pour the melt into deionized water for rapid cooling, and dry to obtain fragments of glass melt; grind and pass through a 100-mesh sieve to obtain glass powder. Mix glass powder with epoxy resin, polyacrylamide, isopropanol and toluene (weight ratios are 84%, 1.5%, 0.5%, 9%, 5%) into a slurry, which is uniformly dispersed by ball milling in a ball mill; casting Shape, dry naturally, and then cut the embryo body into the desired shape; place the embryo body on the part to be sealed, heat it up in an...
