Ka uhi ʻana o ka paipu silikona carbide: Pehea e hana ai ka "pale kaua ʻike ʻole ʻia" o nā paipu ʻoihana?

I ka hana ʻoihana hou, ua like nā ʻōnaehana paipu me nā "kīʻaha koko" o ke kino kanaka, e hana ana i ka hana koʻikoʻi o ka lawe ʻana i nā mea wela kiʻekiʻe a me nā mea ʻino.uhi silicon carbide (SiC)Ua like ka ʻenehana me ke kau ʻana i kahi papa o nā pale kaua hana kiʻekiʻe ma luna o kēia mau "kīʻaha koko", e hāʻawi ana i ka pipeline i ka ikaika o ke kaomi ʻana, ke kūpaʻa i ka pala, a me ke kūpaʻa wela kiʻekiʻe. Pehea e pale ai kēia papa pale maʻalahi i ka hana paʻa o nā pipelines?
1, Nā waiwai mea: ʻO ke "talena kūlohelohe" o ka silicon carbide
Ua kapa ʻia ʻo Silicon carbide ʻo "ka daimana ʻeleʻele ʻoihana", a ʻo kona ʻano atomika he kristal pūnaewele ʻekolu-dimensional i haku ʻia me nā pilina covalent ma waena o ka silicon a me ke kalapona, e hāʻawi ana iā ia me ʻekolu mau waiwai koʻikoʻi:
1. Paʻakikī papa daimana (ʻelua wale nō i ka daimana ma ka paʻakikī Mohs), hiki ke pale aku i ka ʻānai ʻana o nā ʻāpana
2. Ka inertness kemika ikaika loa, kū i nā mea ʻino e like me nā waikawa, nā kumu, a me nā paʻakai
3. Kūlana kūpaʻa wela maikaʻi loa, e mālama ana i ke kūpaʻa kūkulu ʻana i nā mahana kiʻekiʻe o 1350 ℃
ʻO kēia waiwai mea e lilo ai ia i mea pale kūpono no nā kūlana hana koʻikoʻi.
2, ʻōnaehana palekana: ʻōnaehana pale ʻekolu
Ke hoʻopili ka uhi silicon carbide i ka paia o loko o ka pipeline, hana ia i nā papa he nui o ka pale:
Papa pale kino: hoʻokaʻawale pololei nā kristal silicon carbide mānoanoa i ka medium mai ka hoʻopili ʻana me ke kino paipu metala
Papa paʻa kemika: ke hana ʻana i kahi kiʻiʻoniʻoni oxide pale ma o ka hopena passivation, e pale ikaika ana i ka palaho
ʻAe kēia ʻano pale hui i nā pipelines e mālama i ka kūpaʻa o ke kūkulu ʻana ma lalo o nā kūlana paʻakikī e like me ka pala ikaika, ke kāʻei kiʻekiʻe, a me nā wahi mahana kiʻekiʻe.

3, ʻO ka mea huna i ka hana lōʻihi: ka hiki ke ho'ōla pono'ī
Ua ʻike ʻia ma ka noiʻi hou loa he hiki ke hoʻohui hou ʻia ka ʻili o ka silicon carbide ma lalo o nā kūlana hana kikoʻī. Ke hōʻino ʻia ka microscopic, e hoʻonohonoho hou ʻia nā ʻātoma silicon manuahi ma luna o ka ʻili o ka mea i kahi ʻano wela kiʻekiʻe, e hoʻoponopono hapa ana i nā hemahema o ka ʻili. Hoʻonui nui kēia hiʻohiʻona i ke ola lawelawe o ka lining a hoʻemi i ka pinepine o ka mālama ʻana.
4, Nā pono ʻike ʻole ʻia: ka waiwai piha o ke ola holoʻokoʻa
Ke hoʻohālikelike ʻia me nā mea uhi kuʻuna, lawe mai ka uhi silicon carbide i nā pono waiwai huna akā nui i nā ʻoihana ʻoihana ma ka hōʻemi ʻana i ka helu o nā pani no ka mālama ʻana, e hoʻohaʻahaʻa ana i ka pilikia o ka haumia waena, a me ka hoʻolōʻihi ʻana i ke kaʻina hana hoʻololi pipeline. ʻOi loa aku ma nā kahua o nā kemika maikaʻi a me ka hoʻomākaukau ʻana i nā mea ikehu hou, ʻoi aku ka paʻakikī o ke ana ʻana i ka waiwai o ka hōʻoia maʻemaʻe o nā mea me ka ʻikepili maʻalahi.
Me ka hoʻomohala ʻana o ka ʻenehana ʻoihana i ka ʻoi aku ka maikaʻi a me ke aloha i ke kaiapuni, ke ulu nei ka ʻenehana uhi silicon carbide mai ka "pale kūikawā" a i ka "hoʻonohonoho maʻamau". ʻO kēia hopena e hoʻohui i ka ʻepekema mea a me ka naʻauao ʻenekinia e pale mālie i ka "laina ola" o ka ʻoihana hou a lilo i kākoʻo loea koʻikoʻi no ka hoʻomaikaʻi ʻana i ka maikaʻi a me ka pono o nā ʻoihana hana.
