I ka ʻoihana hou, ʻo ka nānā ʻana i ka wela kūpono he ʻāpana koʻikoʻi o ka mālama kaʻina hana, hōʻoia maikaʻi, a me nā ʻōnaehana palekana. Hōʻike pinepine ʻia nā Thermocouples—nā mea ʻike wela i hoʻohana nui ʻia i nā kaiapuni paʻakikī e like me nā wela kiʻekiʻe, nā kemika corrosive, nā ʻōnaehana vacuum, a me nā kahua plasma. ʻO ka pale ʻana i kēia mau mea ʻike pono he mea nui ia no ka paʻa o ka hana. ʻO nā paipu Sapphire, i hana ʻia mai ka synthetic single-crystal aluminum oxide, ua hōʻoia ʻia i waena o nā mea hilinaʻi loa no ia pale. Ke ʻimi nei kēia ʻatikala i nā hiʻohiʻona kūʻokoʻa o nā paipu sapphire, kā lākou hoʻohana like ʻole, a ʻoi aku hoʻi, kā lākou hana ʻokoʻa ma ke ʻano he pale pale thermocouple.

Mea Kiekie no na noi koi

ʻO ka Sapphire kahi ʻano crystalline o ka alumini oxide (Al₂O₃) a ua helu ʻia ma lalo o ke daimana ma ke ʻano o ka paʻakikī, e helu ana i ka 9 ma ka pālākiō Mohs. ʻO kēia paʻakikī koʻikoʻi ke kūpaʻa ʻana i nā paipu sapphire i ka ʻoki ʻana, abrasion, a me ka hopena mechanical, ʻoiai ma lalo o ka hoʻohana pinepine ʻana a ikaika paha.

Ma waho aʻe o ka ikaika mechanical, mahalo nui ʻia nā paipu sapphire no ko lākou kūpaʻa kemika. Paʻa a paʻa lākou i mua o ka hapa nui o nā waikawa, nā mea hoʻoheheʻe, a me nā kinoea reactive, me ka hydrogen fluoride, chlorine, a me nā pūhui sulfur. ʻAe kēia iā lākou e hana maikaʻi i nā kaʻina hana e pili ana i nā kemika koʻikoʻi a i ʻole plasma.

Eia kekahi, kupaianaha ka hana wela o ka sapphire. Kūleʻa ia i ka ʻike lōʻihi i nā mahana a hiki i ka 2000 ° C me ka mālama ʻana i kona kūpaʻa. Kākoʻo kona conductivity wela i ka hoʻololi wela, kahi hiʻohiʻona koʻikoʻi ke hoʻohana ʻia i nā ʻōnaehana ʻike wela.

ʻO kekahi pōmaikaʻi koʻikoʻi ʻo ia ka ʻike ʻike ʻike ma waena o nā ultraviolet, ʻike ʻia, a me nā lōʻihi nalu infrared-mai kahi o 0.3 μm a i 5 μm. Hana kēia i nā paipu sapphire i kūpono no ka ʻike maka a i ʻole nā ​​ʻōnaehana nānā thermal-optical hui pū.

Nā Thermocouple a me ka Pono no ka Palekana

He mea nui nā Thermocouple i nā ʻōnaehana ākea, mai nā kapuahi kila a me nā ʻenekini turbine i nā reactors semiconductor a me nā mea hana kemika. Hoʻokumu kēia mau mea hana i ka volta e pili ana i ka ʻokoʻa wela ma waena o ʻelua metala like ʻole i hoʻohui ʻia ma kekahi ʻaoʻao. ʻOiai he maʻalahi a paʻa ka thermocouple, hiki i ko lākou ʻike pololei ʻana i ka wela, nā mea ʻino, a me nā haʻalulu mechanical hiki ke hoʻopōkole i ko lākou ola lawelawe a hoʻohaʻahaʻa paha i ka pololei o nā heluhelu wela.

ʻO kēia kahi e pāʻani ai nā paipu sapphire ma ke ʻano he pale pale. Ma ka hoʻopaʻa ʻana i ka thermocouple i loko o kahi paipu sapphire, ua hoʻokaʻawale ʻia ka mea ʻike mai ke kaiapuni paʻakikī ʻoiai e ʻae ana i ka hoʻoili wela kūpono. ʻO ka hopena he mea ʻike lōʻihi, ʻoi aku ka hilinaʻi e mālama i ka pololei mau ʻoiai ma hope o ka loaʻa ʻana o nā kūlana hana koʻikoʻi.

Hiki i ka wela wela o Sapphire ke hiki koke aku i ka thermocouple me ka like ole, e hoemi ana i ke kau wela a me ka hooikaika ana i ka manawa pane. Eia kekahi, ʻo kona kūʻē ʻana i ka hoʻouka kaua kemika e hōʻoia ʻaʻole e hoʻopilikia ʻia ka sensor e nā koena, corrosion, a i ʻole ke kūkulu ʻana i nā mea - nā pilikia e hoʻopilikia pinepine i nā lima lima pale metala.

E hoʻohana i nā hihia ma ka nānā ʻana i ka wela

I loko o nā umu wela wela, hoʻohana mau ʻia nā paipu sapphire e pale i nā thermocouple e nānā i nā kūlana kaʻina hana koʻikoʻi. He mea nui ko lākou kūpaʻa kemika i nā lewa i waiwai i nā kinoea halogen, nā metala hoʻoheheʻe ʻia, a i ʻole nā ​​​​huhū reactive. ʻo kahi laʻana:

  • Hana Hana Semiconductor: Mālama nā ʻahu Sapphire i nā thermocouple i ka wā ulu epitaxial, wafer annealing, a me nā kaʻina hana doping, kahi e koʻikoʻi ai nā kaiapuni maʻemaʻe a me ka mālama ʻana i ka wela.

  • Nā mea hoʻoheheʻe kemika: Ma ka catalytic reactions a corrosive vapor environments, sapphire tubes e hōʻoiaʻiʻo i ka lōʻihi o ka pale ʻana i nā mea wela, me ka hoʻopau ʻana i nā hopohopo contamination.

  • Na kapuahi: Kāohi nā paipu Sapphire i ka ho'ohāhā a me ka pō'ino mechanical i nā thermocouple i ka wā e hana ana ma lalo o nā kinoea inert ha'aha'a.

  • Pūnaehana Puhi: Ke hilinaʻi pinepine nei nā ʻenekini jet, nā huila kinoea, a me nā mea puhi ʻoihana i nā thermocouple i pale ʻia i ka sapphire no ka nānā ʻana i nā pae wela loa no ka hoʻokō ʻana a me ka loiloi palekana.

Ma ka hoʻohana ʻana i nā paipu sapphire, hiki i nā mea ʻenekinia ke hoʻokau i nā thermocouple i nā kūlana i ʻole e luku loa ʻia no nā metala maʻamau a i ʻole nā ​​pahu aniani. Hoʻonui kēia i ka laulā hana o nā ʻōnaehana nānā wela a hoʻonui i kā lākou hana lōʻihi.

Nā Hana Hana Hou o nā Tubes Sapphire

ʻOiai ʻo ka pale thermocouple kahi noi alakaʻi, hoʻohana ʻia nā paipu sapphire i nā ʻenehana holomua ʻē aʻe.

  • Nā kukui hoʻokuʻu kiʻekiʻe (HID).: E like me nā mea envelopp, ʻo nā paipu sapphire ke kū i ka wela nui a me ka radiation UV/IR me ka ʻole o ke ao a palupalu.

  • Nā Keʻena Etching Plasma: Hoʻohana ʻia ma ke ʻano o nā awa nānā a me nā moku hoʻopaʻa ʻia ma muli o ko lākou pale ʻana i ka erosion.

  • Inline Optical Sensing: E ho'ā i ka spectroscopy, imaging, a me ka laser diagnostics ma ke kaʻina hana pipeline me ka ʻole o ka hoʻohaumia ʻana i ke kikowaena.

  • Lapaau Wai a me na Lapaau Lapaau: Ma muli o kā lākou bio-inertness a me ke kū'ē kemika, kūpono nā paipu sapphire no nā ʻōnaehana e koi ana i ka sterility a me ka non-reactivity.

  • Nā Pūnaehana Hoʻouna Laser: E alakaʻi nā paipu Sapphire i nā kukuna mana kiʻekiʻe me ka liʻiliʻi o ka pohō ʻike a me ke kūpaʻa wela kiʻekiʻe.

Loaʻa kēia mau noi mai nā waiwai koʻikoʻi o ka sapphire—kemika inertness, optical clarity, high hardness, and thermal stability—ma nā ʻoihana like ʻole e like me ka aerospace, mālama ola kino, petrochemical, a me nā uila.

Nā Pono Kino Kuleana o nā Paipu Sapphire

  1. Laulā ʻAlohilohi: 0.3–5.0 μm (UV i IR), kūpono no ka hoʻohana ʻana i ka ʻike, laser, a me ka spectroscopic.

  2. ʻoʻoleʻa: Mohs 9—kue i ka abrasion a me ka poino o ka ili

  3. Kū'ē wela: Paʻa a hiki i 2030 ° C, me ka conductivity kiʻekiʻe no ka hoʻololi wela wikiwiki

  4. Paʻa Kemika: Impervious i ka nui o nā mea hoʻoheheʻe, nā ʻakika, a me nā alkali

  5. Hoʻokohu Uila: Paʻa dielectric mau a haʻahaʻa dielectric poho

  6. Paʻa Paʻa: Kūleʻa i ka hoʻonui wela a me ka deformation ma lalo o ke kaomi

  7. Kūʻē Plasma: He kūpono no ka hoʻohana ʻana i nā māla ikaika nui e like me PECVD a i ʻole ka implantation ion

Hōʻuluʻulu a me nā pono no nā ʻōnaehana Thermocouple

  1. Lawe mai nā paipu Sapphire i kahi hui like ʻole o nā hiʻohiʻona i kūpono iā lākoupale thermocouple:

    • Hoʻonui i ka pololei: Hiki ke pane wikiwiki

    • Hoʻopaʻa Paʻa: ʻO ke kū'ē i kaʻaʻahu a me ka corrosion e pale i nā meaʻike no ka wā lōʻihi

    • Hana Paa: Mālama i ka pono mechanical a hiki i ke kaʻa kaʻa kaʻa wela

    • Hoʻohaumia ʻole: ʻO nā ʻili inert kemika e hōʻemi i nā kumu hewa

    • Hiki i ka Multifunctional: Hiki ke hoʻohui i ka ʻike maka me ka nānā wela

Ka hopena

  1. Aia nā Thermocouples i ka puʻuwai o nā ʻōnaehana pale wela, a hilinaʻi nui ko lākou hilinaʻi i ka maikaʻi o ko lākou hale pale. ʻO nā paipu Sapphire, mahalo i kā lākou waiwai waiwai, hāʻawi i ka hui maikaʻi loa o ka pale wela, ka pale mechanical, a me ka maʻemaʻe kemika. Ke hoʻomau nei nā ʻoihana i ka ʻoi aku ka pololei a me ka lōʻihi o nā ʻōnaehana wela, ua lilo nā thermocouple i pale ʻia i ka sapphire tube i mea pono no ka hoʻokō ʻana i kēlā mau manaʻo.
