Paipu pale thermocouple Silicon carbide
ʻO Silicon Carbide Thermocouple Protection Tube: Palekana Hana Kiʻekiʻe no nā Kūlana Loa
He aha nā pono o ka Silicon Carbide Thermocouple Protection Tubes?
ʻO nā paipu pale thermocouple Silicon carbide, i ʻike ʻia no ko lākou lōʻihi loa a me ka hana, he mea nui i nā noi e koi ana i ka pololei a me ke kūpaʻa o ke ana wela kiʻekiʻe. Me ke kū ʻana o ka wela a hiki i 1550°C (2800°F), pale pono nā paipu silicon carbide i nā thermocouples mai nā wahi paʻakikī, e hōʻoiaʻiʻo ana i ka pololei i nā ʻoihana e like me ka hoʻoheheʻe aluminika, metallurgy, a me nā seramika. ʻO nā waiwai kūʻokoʻa o ka silicon carbide e hiki ai iā ia ke pale aku i ka oxidation, corrosion, a me ka haʻalulu wela - ʻoi aku ka maikaʻi ma mua o nā mea kahiko e like me ka alumina a me ka graphite i nā noi kikoʻī.
No ke aha e koho ai i ka Silicon Carbide no ka Thermocouple Protection?
ʻO Silicon carbide, kahi mea ʻenehana paʻakikī me ka conductivity thermal kiʻekiʻe a me ke kūpaʻa kūʻokoʻa i ka lole kemika, hāʻawi i ka pale ikaika i nā metala hoʻoheheʻe e like me ka alumini a me ka zinc. Eia ka mea e kū ai:
- Kiʻekiʻe Thermal Conductivity: ʻO ka maikaʻi o ka hoʻoili wela o ka Silicon carbide e hōʻoia i ka hoʻololi wela, hoʻomaikaʻi i ka ʻike wela a me ka pololei i nā noi manawa maoli.
- ʻO ka ʻoki ʻana a me ka pale ʻana: Paʻa mau ka mea ʻoiai ke ʻike ʻia i nā kinoea corrosive a i ʻole metala hoʻoheheʻe ʻia, e pale ana i nā thermocouples mai ka hōʻino ʻana a hoʻolōʻihi i ko lākou ola.
- Haʻahaʻa Porosity: Me kahi pae porosity ma kahi o 8%, nā paipu thermocouple silicon carbide e pale i ka hoʻohaumia a mālama i ka kūpaʻa kiʻekiʻe ma lalo o nā wela kiʻekiʻe.

Hoʻohana pinepine ʻia kēia mau paipu i nā umu wela wela a me nā umu hoʻoheheʻe alumini, kahi e kōkua ai kā lākou haʻahaʻa haʻahaʻa me ka alumini hoʻoheheʻe ʻia e hōʻemi i ka pono no ka mālama pinepine ʻana. Eia kekahi, ʻo ka ikaika koʻikoʻi o ka silicon carbide a me ke kūpaʻa ʻana e lilo ia i mea koho maikaʻi loa no ka lawelawe lōʻihi ʻana i nā kiln ʻoihana a me nā umu ahi, kahi e pale pono ai i ka hoʻouka ʻana a me ka oxidation.
Nā nīnau i nīnau pinepine ʻia (FAQ)
1. Pehea ka hoʻohālikelike ʻana o ka carbide silicon me nā mea paipu pale pale ʻē aʻe?
ʻOi aku ka silikoni carbide ma mua o ka alumina a me nā seramika ʻē aʻe i nā noi wela kiʻekiʻe ma muli o kona kūpaʻa haʻalulu wela a me ka paʻa o ka oxidation. ʻOiai hiki i ka alumina a me ka silicon carbide ke kū i nā wela kiʻekiʻe, ʻoi aku ka maikaʻi o ka silicon carbide i nā wahi kahi e loaʻa ai nā metala hoʻoheheʻe a me nā kinoea corrosive.
2. He aha ka mālama ʻana no nā paipu pale silicon carbide?
Hiki i ka hoʻomaʻemaʻe maʻamau a me ka hoʻomehana ʻana ke hoʻonui i ko lākou ola, ʻoi aku hoʻi ma nā wahi hoʻohana mau. Manaʻo ʻia ka mālama ʻana i ka ʻili i kēlā me kēia 30-40 mau lā e hoʻomaikaʻi i ka hana.
3. Hiki ke hoʻopilikino ʻia nā paipu pale silicon carbide?
ʻAe, loaʻa kēia mau paipu i nā ʻano lōʻihi a me nā anawaena a hiki ke hoʻopili ʻia me nā mea pono NPT i hoʻopaʻa ʻia e kūpono i nā hoʻonohonoho ʻenehana like ʻole.
I ka hōʻuluʻulu ʻana, hāʻawi nā paipu pale thermocouple silicon carbide i ka lōʻihi like ʻole, ka pololei, a me ka pale ʻana i ka corrosion, e hoʻolilo iā lākou i mea waiwai nui i nā ʻoihana kiʻekiʻe a me ka pololei.
