Paipu pale pale silikoni

I nā ʻoihana kahi e hoʻoweliweli ai nā kūlana koʻikoʻi i ka pono o nā mea hana,mau paipu pale kilikaka (SiC).e puka mai ma ke ʻano he haʻina haʻihaʻi. ʻAʻole like me nā mea pale maʻamau, hui pū ʻo SiC tubes i ka ʻepekema waiwai kiʻekiʻe me ka ʻenehana ikaika e pale i nā mea hana koʻikoʻi a me nā kaʻina hana.

1. Palekana ʻAʻole like ʻole i nā Kūlana Kūʻē

Hana nā paipu pale SiC ma ke ʻano he lālani pale mua i nā wahi kahi i koho ʻole ʻia ai ka hemahema:

（1）Ke pale wela: E kū i nā mahana hoʻomau a hiki i 1600°C, nā mea ʻike pale, nā thermocouples, a i ʻole nā ​​​​probes mai nā metala hoʻoheheʻe, nā lapalapa, a me ka plasma.

（2）Ka palekana kemika: E pale i ka ʻino mai nā waikawa (e laʻa me sulfuric, hydrochloric), alkalis, a me nā kinoea reactive e like me ka chlorine a i ʻole sulfur oxides.

Palekana Abrasion: E pale aku i nā ʻāpana erosive i loko o nā moena wai, nā mea hoʻoheheʻe lanahu, a i ʻole nā ​​​​hana eli.

2. Ka pololei a me ka paʻa no nā ana koʻikoʻi

I nā kaʻina hana ʻoihana kiʻekiʻe, ʻo ka pololei ka mea nui. Hoʻonui nā paipu SiC i ka hilinaʻi ma o:

（1） Hoʻemi i ka hoʻopilikia ʻana i ka hōʻailona: ʻAʻole nā ​​​​mea hoʻokele e pale i nā pilikia electromagnetic i nā mea ʻike uila.

（2）Hoʻopaʻa wela: ʻO ka hoʻololi ʻana i ka wela ma kahi kokoke-zero e hōʻoia i ka alignment mau a me ke ana pololei ʻana ma lalo o ka wikiwiki o ka wela.

（3）Gas-Tight Integrity: Kāohi ka hale impermeable i ke komo ʻana o ke kinoea, mea koʻikoʻi no nā ʻōnaehana vacuum a i ʻole nā ​​lewa hoʻomalu.

3. E ho'ā ana i nā ʻenehana hou aʻe i nā ʻenehana pale SiC e wehe i nā mea hou i nā kula e kū mai ana.

（1）Hydrogen Economy: E lawelawe ma ke ʻano he mau puʻu paʻa no nā mea ʻike i ka hana ʻana o ka hydrogen, ka mālama ʻana, a me nā keena wahie, e kūʻē i ka embrittlement a me ka hōʻike H₂ kiʻekiʻe.

（2）Ka Hana Hana Semiconductor: E pale i nā mea ʻike maka a me ka wela i loko o nā reactors CVD (Chemical Vapor Deposition) mai nā precursors corrosive e like me ka silane a i ʻole ammonia.

（3）Ka ʻImi ʻImi: Nā mea kani pale i nā ʻenekini rocket a me nā ʻimi honua mai nā gradients wela loa a me ka radiation cosmic.

4. Kūʻai-Efficiency Ma o Loihi Ola

ʻOiai ʻoi aku ka kiʻekiʻe o nā kumukūʻai SiC, ʻoi aku ka maikaʻi o kā lākou olaola i ka waiwai:

（1）Ka Hoʻohaʻahaʻa Hoʻohaʻahaʻa: Hoʻopau i nā mea ʻē aʻe metala a i ʻole quartz ma mua o 4-6x i nā hoʻonohonoho abrasive a i ʻole acidic, e hōʻemi ana i ka mālama ʻole ʻia.

（2） Koi ʻia ʻo Zero Coating: ʻAʻole e like me nā metala e pono ana i nā pale pale, ʻo nā waiwai kūlohelohe o SiC e hoʻopau i nā kumukūʻai lapaʻau.

（3） Hoʻohana hou: E ola i nā pōʻai kaʻina hana he nui i nā noi e like me ka hoʻoheheʻe metala a i ʻole ka hana aniani me ka ʻole o ka hōʻino.

5. Hoʻopilikino no nā pono kūikawā

Hoʻololi ʻia nā paipu pale SiC i nā pilikia niche ma o ka ʻenehana i hoʻohālikelike ʻia:

（1）Hybrid Designs: Hoʻohui pū me nā metala a i ʻole nā ​​mea ʻeleʻele no nā hui hana nui (e laʻa i nā mea hoʻohui wili, nā flanges).

（2） Hoʻololi i ka ʻili: ʻO nā loko i hoʻomaʻemaʻe ʻia no nā noi optical a i ʻole nā ​​​​mea i hoʻopaʻa ʻia i waho e hoʻomaikaʻi ai i ka hoʻohemo ʻana i ka wela.

（3）Ka Nui: Hana ʻia mai nā millimeters (nā mea hoʻoheheʻe lab-scale) a i nā mika (nā kiln ʻoihana).

6. Hoʻoponopono hoʻomau

Kākoʻo nā paipu SiC i nā hana ʻoihana pili i ka kaiaola:

（1）Hoʻokohu ʻenehana: Hoʻemi ka maikaʻi wela kiʻekiʻe i ka hoʻohana ʻana i ka wahie umu a hiki i ka 20% ke hoʻohālikelike ʻia me nā pale metala.

（2）Hoemi ʻino: Hoʻopau ke ola lōʻihi i ka ʻōpala waiwai mai ka hoʻololi pinepine ʻana.

（3）Ka hoʻohaʻahaʻa ʻana i ka ʻawaʻawa: Hoʻopau i ka pono o nā uhi pōʻino (e laʻa, nā nickel-based alloys) i loko o nā wahi ʻino.

ʻO Shandong Zhongpeng Special Ceramics Co., Ltd ʻo ia kekahi o ka silicon carbide ceramic mea hoʻonā hou i Kina. ʻO ka ʻenehana loea SiC: ʻO 9 ka paʻakikī o Moh (ʻo 13 ka paʻakikī o New Moh), me ke kūpaʻa maikaʻi loa i ka erosion a me ka corrosion, abrasion maikaʻi loa - kūpaʻa a me ka anti-oxidation. ʻO ke ola lawelawe o ka huahana SiC he 4 a 5 mau manawa lōʻihi ma mua o 92% alumina mea. ʻO ka MOR o RBSiC he 5 a 7 mau manawa o ka SNBSC, hiki ke hoʻohana ʻia no nā ʻano paʻakikī. He wikiwiki ke kaʻina hana, ʻo ka hāʻawi ʻana e like me ka mea i ʻōlelo ʻia a ʻoi aku ka maikaʻi o ka lua. Hoʻomau mau mākou i ka hoʻokūkū i kā mākou mau pahuhopu a hāʻawi i ko mākou naʻau i ke kaiāulu.
