Zvigadzirwa zvechubhu yekudzivirira yesafire thermocouple zvinoshandiswa mumaindasitiri. Kristaro imwe chete Al2O3

Tsananguro pfupi:

Chubhu inodzivirira yesapphire thermocouple inotsiva chubhu yeceramic zvachose nekuti ine simba rekudzivirira simbi. Dzimwe simbi dzinoita nemachubhu eceramic ane lead, zvichiita kuti dzive nyore kukuvara, senge mumaoven ekuputika ekugadzira girazi re pre-lead. Hapana mubvunzo wakadaro kana uchishandisa chubhu inodzivirira yesapphire thermocouple yatinopa.

Chubhu yekudzivirira yeSapphire thermocouple ichubhu yekudzivirira yesapphire thermocouple inodzivirira kupisa kwakanyanya uye sleeve yekudzivirira yesapphire thermocouple, inokura zvakananga kubva kukristaro imwe chete yesapphire panguva imwe chete, yakakodzera kutsiva chubhu yekudzivirira yecorundum thermocouple sesleeve yekudzivirira yesapphire, yakakodzera kudzivirirwa kwesapphire thermocouple munzvimbo dzinopisa zvakanyanya uye dzine ngura yakawanda, uye yave kutsiva sleeve yekudzivirira yesapphire thermocouple.

Hunhu hwechubhu inodzivirira yesafire

1. Kudzivirira kupisa nekumanikidzwa kwakanyanya: Machubhu edu eKY neEFG sapphire anogona kutsungirira kupisa kwakanyanya kusvika 2000 degrees Celsius, zvakare kutsungirira kumanikidzwa kwakanyanya nekuora kwemakemikari, uye ane kudzivirirwa kwakanaka kwemakemikari kupfuura machubhu ekudzivirira ecorundum.

2. Kuchena kwakanyanya: Chubhu yedu yeEFG yesafire inoshandisa tekinoroji yekuumba yekukura kwekristaro imwe chete, kuchena kusvika ku99.998%, kuchena kwakanyanya kunovimbisa mukana wekushanda kwesafire.

3. Kuomarara uye kugara kwenguva refu: Kuomarara kwechubhu yesafire kwakakwira seMohs9, iyo inodzivirira kufa zvakanyanya.

4. Kusimba kwemhepo: Chubhu yedu yesafire inoshandisa tekinoroji yeEFG kuti iumbwe kamwe chete, ine kusimba kwemhepo 100%, ichidzivirira kupinda kwegasi rakasara uye kuramba ngura kwegasi remakemikari, zvichipfuura kushanda kwechubhu yekudzivirira ye corundum thermocouple.

Nekuda kwehunhu hwakanaka hwe thermocouple protective sleeve yataurwa pamusoro apa, chinhu chakanaka kwazvo chekushandisa munzvimbo dzakanyanya kupisa dzakadai sekupisa kwakanyanya (2000 degrees Celsius). Thermocouple protective bushing ine zvakanakira zvekushandisa zvakanyanya muindasitiri yemakemikari, kuchenesa mafuta, indasitiri yegirazi uye murabhoritari.

Chubhu inodzivirira yesapphire thermocouple inogona kushandiswa munzvimbo dzisina kugadzikana kwechubhu yeceramic yeemery. Inogona kushandiswa muzvishandiso zvinopisa mafuta akawanda, kugadzira hydrogen, mabhokisi egirazi, maovheni ekuputika, maasidhi asina kugadzirwa (mineral acids), uye kuyerwa kwetembiricha mumabasa esimbi.
