Wehewehe Pōkole:

ʻO nā paipu sapphire, i hana ʻia mai ka alumini oxide kristal hoʻokahi (Al₂O₃), he mau ʻāpana hana kiʻekiʻe i hoʻohana nui ʻia i nā ʻano hana ʻoihana like ʻole. ʻO kā lākou hui pū ʻana o ke kūpaʻa wela, ka ikaika mechanical, ke kūpaʻa kemika, a me ka transparency optical ua hoʻolilo iā lākou i mea nui i nā ʻōnaehana kaiapuni koʻikoʻi. ʻO kekahi o nā noi waiwai nui a hoʻohana nui ʻia ʻo ia ka pale ʻana i nā thermocouples—nā mea ʻike mahana e hana pinepine ana i nā kūlana huhū, wela kiʻekiʻe, a i ʻole nā kūlana corrosive. Hāʻawi kēia ʻatikala i kahi ʻike hohonu o nā waiwai paipu sapphire, nā ʻano koʻikoʻi, nā noi koʻikoʻi, a me kā lākou kuleana i ka pale ʻana i ka thermocouple.

No ke aha e hāʻawi ai nā ʻōmole Sapphire i kēlā hana kiʻekiʻe?

Ua ʻike ʻia nā ʻōmole sapphire no ko lākou hiki ke mālama i ke kūpaʻa o ka hoʻonohonoho ʻana a me ka hana ma lalo o ke kaumaha kino a me ke kemika koʻikoʻi. I loko o nā ʻōnaehana kaomi kiʻekiʻe, hoʻohana ʻia lākou ma ke ʻano he mau ipu hoʻopaʻa a me nā puka makani nānā, e hāʻawi ana i kahi wahi palekana a inert no ka nānā ʻana i nā wai a me nā kinoea. Ma muli o ko lākou ikaika compressive kiʻekiʻe a me ke kū'ē ʻana i ke kahakaha ʻana, kūpono hoʻi nā ʻōmole sapphire i nā wahi e pili ana i ka hopena mechanical ikaika a i ʻole ka hoʻokele wela pinepine.

He kū hoʻokahi kēia mau paipu i ko lākou hiki ke hana i nā mahana a hiki i 2000°C me ka palupalu ʻole a i ʻole ke ʻano ʻē. ʻAʻole e like me nā mea keramika a aniani paha, mālama ka sapeiro i kona ʻano a me nā waiwai mechanical ʻoiai i nā mahana kiʻekiʻe. He mea koʻikoʻi kēia hana i nā noi kahi e pono ai nā ana kino kūlike no ka sila ʻana, ka insulation, a i ʻole ke kaulike ʻana—e like me nā ʻōnaehana hale thermocouple.

ʻO ko lākou ʻike maka ma waena o kahi ākea ākea—mai ka ultraviolet (0.3 μm) a hiki i ka ʻike ʻia a i ka infrared (5 μm)—e hoʻohui i kahi papa hana ʻē aʻe. ʻAe kēia hiʻohiʻona i nā paipu sapphire ʻaʻole wale e hana ma ke ʻano he mau ʻāpana kūkulu akā e kākoʻo pū i nā ʻōnaehana optical i hoʻohui ʻia no ka nānā ʻana i ka manawa maoli a me nā ana laser.

Nā Paipu Sapphire i ka Palekana Thermocouple

He mau mea ʻike mahana koʻikoʻi nā Thermocouples i hoʻohana ʻia ma nā ʻoihana mai ka aerospace a me ka metallurgy a hiki i ka hana semiconductor a me ka hana kemika. Eia nō naʻe, he mau mea hana koʻikoʻi nā thermocouples e hiki ke hoʻohaumia koke i ka wā e hōʻike pololei ʻia ai i nā kinoea reactive, nā wahi plasma, a i ʻole nā pōʻaiapuni hoʻomehana/hoʻoluʻu wikiwiki. No ka pale ʻana i kēia mau pilikia, lawelawe nā paipu sapphire ma ke ʻano he mau pale pale kūpono no nā thermocouples.

ʻO ka conductivity thermal o ka sapphire e hōʻoiaʻiʻo i ka hoʻoili wela wikiwiki a pololei i ka thermocouple i loko o ka paipu, e ʻae ana i ka nānā ʻana i ka mahana manawa maoli me ka pale ʻana i ka sensor mai nā mea ʻino, ka abrasion mechanical, a me ka haʻalulu thermal. ʻO kēia kaulike o ka insulation a me ka conduction e hana ai i nā paipu sapphire i kūpono loa no ka pale ʻana i ka thermocouple i nā wahi ʻino.

Eia kekahi, ʻo ka inertness kemika o ka sapphire e pale aku i kekahi haumia o ke kaʻina hana. He mea nui loa kēia i nā noi maʻemaʻe kiʻekiʻe e like me ka hana ʻana o ka semiconductor wafer, nā ʻōnaehana sterilization lapaʻau, a i ʻole nā keʻena wela vacuum kiʻekiʻe. ʻO ka nele o ka hopena ma waena o ka sapphire a me nā kemika hoʻouka kaua e like me ka plasma fluorine, ka waikawa hydrochloric, a i ʻole nā metala i hoʻoheheʻe ʻia e hōʻoiaʻiʻo i ka hilinaʻi o ka ʻōnaehana a me ka pololei o ke ana.

Eia kekahi, kūpaʻa loa nā ʻōmole sapphire i ke komo ʻana a ʻaʻole e pala i lalo ma lalo o ka hoʻohana lōʻihi ʻana i nā ʻāpana ikehu kiʻekiʻe a i ʻole ka radiation UV/IR ikaika. Hoʻolōʻihi kēia paʻa i ke ola o nā sensor thermocouple, e hōʻemi ana i nā kumukūʻai mālama a me ka manawa hana ʻole o ka ʻōnaehana.

Nā Hoʻohana Laulaha o nā Paipu Sapphire

ʻOiai ʻo ka pale thermocouple kekahi o nā noi kū i waho, hoʻohana nui ʻia nā paipu sapphire i nā ʻoihana ʻenehana kiʻekiʻe a me nā ʻoihana ʻē aʻe. ʻO kēia mau mea:

Ka Hana ʻana i ka PlasmaHana nā ʻōmole sapphire ma ke ʻano he mau pā i loko o nā ʻōnaehana etching plasma a me ka waiho ʻana, kahi e pale ai ko lākou kūpaʻa kemika i ka hana ʻana o nā ʻāpana.
Kukui Wela KiʻekiʻeʻO ko lākou ʻike moakāka a me ke kūpaʻa wela e hoʻolilo iā lākou i mau envelopes kūpono no nā UV, ʻike ʻia, a me nā ʻākoakoa kukui IR.
Ka Hoʻōla Wai a me ka Hoʻokomo KinoeaHoʻohana ʻia nā ʻōmole sapphire i nā ʻōnaehana kahi e pono ai ka kaohi pololei o nā wai a i ʻole nā kinoea ma lalo o ke kaomi kiʻekiʻe.
Nā Lako Lapaʻau a me nā LapaʻauMa muli o ko lākou mau waiwai bio-inert, palekana nā ʻōmole sapphire no ka hoʻohana ʻana i nā mea i sterilized a i ʻole i hoʻokomo ʻia.
ʻO ka Spectroscopy a me ka loiloi OpticalʻO ko lākou moakāka optical e ʻae i ka hoʻohui maʻalahi ʻana i nā ʻōnaehana spectroscopy no ka ʻike kemika a i ʻole biological.

Ma kēia mau kahua āpau, hāʻawi nā ʻōmole sapphire i ka lōʻihi o ka mechanical a me ke kūpaʻa kemika, e hōʻoiaʻiʻo ana i ka lōʻihi o ka hana ma lalo o nā kūlana hana koʻikoʻi.

Nā ʻano koʻikoʻi o nā paipu Sapphire

Loaʻa i nā paipu sapphire kahi hui kakaikahi o nā waiwai mea i makemake ʻia:

Ka laulā hoʻoili ʻana o ka OpticalMai 0.3 μm (UV) a i 5 μm (IR), kūpono no nā ʻōnaehana laser, ka nānā ʻana i ka optical, a me nā ana in-situ.
Paʻakikī LoaMe ka paʻakikī Mohs o 9, aneane hiki ʻole ke kahakaha ʻia ka sapeiro, ʻoi aku ka daimana ma mua.
Kiko Heheʻe Kiʻekiʻe: Noho paʻa ka ʻōnaehana o ka Sapphire a hiki i ka 2030°C.
Ka Hoʻokele Wela KūikawāHoʻoili pono i ka wela, he mea nui no nā noi thermocouple.
Paʻa KemikaKūpaʻa i nā waikawa, alkalis, a me nā metala hoʻoheheʻe ʻia, koe wale nō nā paʻakai caustic wela.
Ka Hoʻopaʻa Uila KiʻekiʻeKūpono no ka pale uila a me ka insulation uila kiʻekiʻe.
Paʻa AnaMālama i ka pono ma lalo o ke koʻikoʻi wela a i ʻole ke kaumaha mechanical.

Nā Pōmaikaʻi o ka Hoʻohana ʻana i nā Paipu Sapphire no nā Thermocouples

ʻO ka hoʻohui ʻana o nā ʻōmole sapphire i nā ʻākoakoa thermocouple e lawe mai i nā pono he nui:

Hoʻomaikaʻi ʻia ka pololei o ka sensor: Kākoʻo ka conductivity thermal i ka ʻike wikiwiki ʻana i ka mahana.
Ka lōʻihi o ke ola o ka sensorʻO ke kū'ē ʻana i ka pala a me ka abrasion e pale aku i ka thermocouple o loko.
Hoʻemi ʻia ka manawa hana ʻole: Haʻahaʻa ke alapine (frequency) o ka hāʻule ʻana o ka sensor a me nā pono hana hou.
Ka Maʻemaʻe o ka ʻōnaehana: Pale ka inertness kemika i ka haumia, he mea nui no nā kaʻina hana lumi maʻemaʻe.
Nā hana he nui: Hoʻohui i ka palekana wela me ka transparency optical no ka hoʻohana pālua i ka ʻike ʻana a me ka nānā ʻana.
