ʻO ka Sapphire Tube no ka Thermocouple Protection - Ke Kiʻekiʻe-Mahana Kūlohelohe ma nā Kaiapuni Paʻakikī

Sapphire Tube no ka Thermocouple Protection – Kiekie-Mahana Pono i loko o nā Kaiapuni Paʻakikī.

ʻO ka wehewehe pōkole:

ʻO nā paipu Sapphire, i hana ʻia mai ka alumini alumini kalakala hoʻokahi (Al₂O₃), nā mea hana kiʻekiʻe i hoʻohana nui ʻia i nā ʻano hana ʻenehana. ʻO kā lākou hui like ʻole o ka pale ʻana i ka wela, ka ikaika mechanical, ke kūpaʻa kemika, a me ka ʻike ʻike maka ua lilo lākou i mea nui i nā ʻōnaehana kaiapuni. ʻO kekahi o nā noi waiwai nui a hoʻonui ʻia i ka pale ʻana i nā thermocouples-nā mea ʻike wela e hana pinepine i nā kūlana hoʻonāukiuki, wela kiʻekiʻe, a i ʻole nā kūlana ʻino. Hāʻawi kēia ʻatikala i kahi hiʻohiʻona hohonu o nā waiwai sapphire tube, nā hiʻohiʻona koʻikoʻi, nā noi nui, a me kā lākou kuleana i ka pale thermocouple.

No ke aha i hāʻawi aku ai nā Tubes Sapphire i kēlā hana kiʻekiʻe?

Ua ʻike ʻia nā paipu Sapphire no ko lākou hiki ke mālama i ka paʻa a me ka hana ma lalo o ke koʻikoʻi kino a me ke koʻikoʻi. I loko o nā ʻōnaehana kiʻekiʻe, hoʻohana ʻia lākou e like me nā 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 kūʻē ʻana, ua kūpono nā paipu sapphire i nā kaiapuni e pili ana i ka hopena mechanical ikaika a i ʻole ke kaʻa uila wela.

He kūʻokoʻa kēia mau paipu i ko lākou hiki ke hana i nā mahana a hiki i 2000 ° C me ka ʻole o ka palupalu a i ʻole deformation. ʻAʻole e like me nā mea hana seramika a i ʻole nā mea aniani ʻē aʻe, mālama ka sapphire i kona ʻano a me nā waiwai mechanical a hiki i nā wela kiʻekiʻe. He mea koʻikoʻi kēia hana i nā noi kahi e pono ai nā ana kino like ʻole no ka sila ʻana, ka insulation, a i ʻole ka hoʻonohonoho ʻana—e like me nā ʻōnaehana hale thermocouple.

ʻO kā lākou ʻike ākea ma kahi ākea ākea-mai ka ultraviolet (0.3 μm) a hiki i ka infrared (5 μm) - hoʻohui i kahi papa o ka hana. Hāʻawi kēia hiʻohiʻona i nā paipu sapphire ʻaʻole wale e hana ma ke ʻano he mea hoʻolālā akā no ke kākoʻo ʻana i nā ʻōnaehana optical i hoʻohui ʻia no ka nānā ʻana i ka manawa maoli a me nā ana i hoʻokumu ʻia i ka laser.

ʻO nā Tubes Sapphire i ka Thermocouple Protection

ʻO Thermocouples nā mea ʻike wela koʻikoʻi i hoʻohana ʻia ma waena o nā ʻoihana mai ka aerospace a me ka metallurgy a i ka semiconductor fabrication a me ka hana kemika. Eia nō naʻe, ʻo nā thermocouple he mau mea kani hiki ke hoʻohaʻahaʻa koke i ka wā e hōʻike pololei ʻia i nā kinoea reactive, nā wahi plasma, a i ʻole nā pōʻai hoʻomehana/hoʻoluʻu wikiwiki. No ka pale ʻana i kēia mau pilikia, lilo nā paipu sapphire i mea pale pale kūpono no nā thermocouple.

ʻO ka hoʻoili wela o ka sapphire e hōʻoia i ka wikiwiki a me ka pololei o ka hoʻoili wela i ka thermocouple i loko o ka paipu, e ʻae i ka nānā ʻana i ka mahana i ka wā e pale ana i ka sensor mai nā mea corrosive, mechanical abrasion, a me ka haʻalulu wela. ʻO kēia kaulike o ka insulation a me ka conduction e hana i nā paipu sapphire i kūpono i ka pale thermocouple i nā wahi ʻino.

Eia kekahi, ʻo ka inertness kemika o ka sapphire e pale aku i ka hoʻohaumia ʻana o ke kaiapuni kaʻina. He mea koʻikoʻi kēia i nā noi hoʻomaʻemaʻe kiʻekiʻe e like me ka semiconductor wafer processing, nā ʻōnaehana sterilization olakino, a i ʻole nā keʻena wela wela kiʻekiʻe. ʻO ka loaʻa ʻole o ka pane ʻana ma waena o ka sapphire a me nā kemika hoʻopaʻapaʻa e like me ka fluorine plasma, hydrochloric acid, a me nā metala hoʻoheheʻe ʻia e hōʻoia i ka hilinaʻi ʻana o ka ʻōnaehana a me ke ana pololei.

Eia kekahi, paʻa loa nā paipu sapphire i ka ʻaʻahu a ʻaʻole e hoʻohaʻahaʻa ʻia ma lalo o ka ʻike lōʻihi ʻana i nā ʻāpana ikaika kiʻekiʻe a i ʻole ka radiation UV/IR ikaika. Hoʻonui kēia paʻa i ke ola o nā mea ʻike thermocouple, e hōʻemi ana i nā kumukūʻai mālama a me ka downtime ʻōnaehana.

ʻOi aku ka nui o ka hoʻohana ʻana i nā ʻāpana Sapphire

ʻOiai ʻo ka pale thermocouple kekahi o nā noi kūʻokoʻa, hoʻohana nui ʻia nā paipu sapphire i nā ʻenehana kiʻekiʻe a me nā ʻoihana ʻoihana. Aia kēia mau mea:

ʻO ka hana ʻana o ka plasma: Hana nā paipu Sapphire ma ke ʻano he pā i loko o ka etching plasma a me nā ʻōnaehana deposition, kahi e pale ai ko lākou kūpaʻa kemika i ka hana ʻana.
Kukui Mahana Kiekie: ʻO kā lākou māliko a me ke kūpaʻa wela e hoʻolilo iā lākou i nā enveloppi kūpono no nā hui kukui UV, ʻike ʻia, a me IR.
ʻO ka hoʻomaʻemaʻe wai a me ke kinoea: Hoʻohana ʻia nā paipu Sapphire i nā ʻōnaehana kahi e pono ai ka hoʻomalu pono ʻana i nā wai a i ʻole nā kinoea ma lalo o ke kaomi kiʻekiʻe.
Lako Lapaau a Laau Laau: Ma muli o ko lākou mau waiwai bio-inert, palekana nā paipu sapphire no ka hoʻohana ʻana i nā mea hana sterilized a implantable paha.
ʻIkepili a me ka nānā ʻana: Hāʻawi ko lākou ʻike ʻike no ka hoʻohui pono ʻana i loko o nā ʻōnaehana spectroscopy no ka ʻike kemika a i ʻole ke olaola.

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

ʻO nā hiʻohiʻona kumu o nā paipu Sapphire

Loaʻa i nā paipu Sapphire kahi hui like ʻole o nā waiwai waiwai i makemake ʻia:

Laulā Hoʻouna Optical: Mai ka 0.3 μm (UV) a hiki i ka 5 μm (IR), kūpono no nā ʻōnaehana laser, ka nānā ʻana i ka optical, a me nā ana i loko.
Paʻakiki Loa: Me ka Mohs paakiki o 9, sapphire ua aneane scratchproof, wale ma mua o daimana.
Lae hehee Kiekie: Noho paʻa ka Sapphire a hiki i 2030°C.
Kūʻokoʻa Thermal Conductivity: Hoʻololi maikaʻi i ka wela, mea nui no nā noi thermocouple.
Paʻa Kemika: Kūleʻa i nā ʻakika, alkalis, a me nā metala hoʻoheheʻe ʻia, koe naʻe nā paʻakai wela.
Hoʻokuʻu Uila Kiʻekiʻe: He kūpono no ka uila uila a me ka uila kiʻekiʻe.
Paʻa Paʻa: Mālama i ka pono ma lalo o ke kaumaha wela a i ʻole ka ukana mechanical.

Nā pōmaikaʻi o ka hoʻohana ʻana i nā paipu Sapphire no nā Thermocouple

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

Hoʻomaikaʻi ʻia ka pololei o ka sensor: Kākoʻo ka wela wela i ka ʻike wela.
Hoʻonui ʻia ke ola o ka sensor: ʻO ke kūʻē ʻana i ka ʻino a me ka abrasion e pale i ka thermocouple i loko.
Hoʻemi ʻia ka manawa hoʻomaha: ʻO ke alapine haʻahaʻa o ka hemahema o ka sensor a me ka pono e hoʻoponopono hou.
Pūnaehana Maʻemaʻe: ʻO ka inertness kemika e pale i ka hoʻohaumia ʻana, pono no nā kaʻina hana maʻemaʻe.
Nui-hana: Hoʻohui i ka pale wela me ka ʻike maka no ka hoʻohana ʻelua i ka ʻike a me ka nānā ʻana.

Ka hopena

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

Hoʻomaikaʻi ʻia ka pololei o ka sensor: Kākoʻo ka wela wela i ka ʻike wela.
Hoʻonui ʻia ke ola o ka sensor: ʻO ke kūʻē ʻana i ka ʻino a me ka abrasion e pale i ka thermocouple i loko.
Hoʻemi ʻia ka manawa hoʻomaha: ʻO ke alapine haʻahaʻa o ka hemahema o ka sensor a me ka pono e hoʻoponopono hou.
Pūnaehana Maʻemaʻe: ʻO ka inertness kemika e pale i ka hoʻohaumia ʻana, pono no nā kaʻina hana maʻemaʻe.
Nui-hana: Hoʻohui i ka pale wela me ka ʻike maka no ka hoʻohana ʻelua i ka ʻike a me ka nānā ʻana.
