Silicon carbide pipeline lining: Pehea e hana ai ka "mea kaua i ʻike ʻole ʻia" o nā pipeline ʻoihana?

I ka hana ʻenehana hou, ʻo nā ʻōnaehana pipeline e like me nā "moku koko" o ke kino o ke kanaka, e hana ana i ka hana koʻikoʻi o ka lawe ʻana i nā media kiʻekiʻe a me ka corrosive. ʻO kakaʻa kalapona silika (SiC).ʻenehana e like me ke kau ʻana i kahi papa o nā mea kaua kiʻekiʻe ma luna o kēia mau "moku koko", e hāʻawi ana i ka pipeline ikaika compressive, corrosion-resistant, a me ke kūpaʻa wela kiʻekiʻe. Pehea e pale ai kēia ʻāpana pale maʻalahi i ka hana paʻa o nā pipeline?
1 、 Nā waiwai waiwai: ʻO ka "talena kūlohelohe" o ka carbide silika
Ua ʻike ʻia ʻo Silicon carbide ʻo "industrial black daimana", a ʻo kona ʻano atomic he ʻekolu-dimensional network crystal i haku ʻia me nā paʻa covalent ma waena o ke silika a me ke kalapona, e hāʻawi ana iā ia me ʻekolu mau waiwai nui:
1. ʻO ka paʻakikī papa daimana (ʻelua wale nō i ke daimana ma ka paʻakikī Mohs), hiki ke pale aku i ka ʻinoʻino
2. ʻO ka inertness kemika ikaika loa, kū i ka media corrosive e like me nā waikawa, nā kumu, a me nā paʻakai.
3. ʻO ke kūpaʻa wela maikaʻi loa, e mālama ana i ka paʻa o ke kūkulu ʻana a hiki i nā wela kiʻekiʻe o 1350 ℃
Hana kēia waiwai waiwai i mea pale kūpono no nā kūlana hana koʻikoʻi.
2、 Mekanika pale: ʻōnaehana pale ʻekolu
Ke hoʻopili ʻia ka lining silicon carbide i ka paia o loko o ka pipeline, hana ia i nā ʻāpana he nui o ka pale:
Papa pale kino: hoʻokaʻawale pololei nā kristal kalapona silika ʻeleʻele i ke kino mai ka hoʻopili ʻana me ke kino paipu metala.
Lapa paʻa kemika: hana ʻana i kahi kiʻiʻoniʻoni ʻokikene pale ma o ka hopena passivation, kūʻē ikaika i ka corrosion
Hiki i kēia ʻenehana pale composite i nā pipelines e mālama i ka kūpaʻa o ke kūkulu ʻana ma lalo o nā kūlana paʻakikī e like me ka corrosion ikaika, ka lole kiʻekiʻe, a me nā wahi wela kiʻekiʻe.

3、 ʻO ka mea huna i ka hana lōʻihi: hiki ke ho'ōla iā ia iho
Ua ʻike ʻia ka noiʻi hou loa i loaʻa i ka silicon carbide ka hiki ke hoʻohui hou i ka ʻili ma lalo o nā kūlana hana. Ke loaʻa ka pōʻino microscopic, e hoʻonohonoho hou nā ʻātoma silika manuahi ma ka ʻili waiwai i kahi kaiapuni wela kiʻekiʻe, e hoʻoponopono ana i nā hemahema o ka ʻili. Hoʻonui nui kēia hiʻohiʻona i ke ola lawelawe o ka lining a hōʻemi i ka alapine mālama.
4、 Nā pōmaikaʻi ʻike ʻole ʻia: ka waiwai holoʻokoʻa
Ke hoʻohālikelike ʻia me nā mea lining kuʻuna, lawe mai ka lining silicon carbide i nā pono waiwai huna akā nui i nā ʻoihana ʻoihana ma o ka hōʻemi ʻana i ka nui o nā pani no ka mālama ʻana, e hoʻohaʻahaʻa i ka hopena o ka pollution medium, a me ka hoʻonui ʻana i ka pōʻai hoʻololi pipeline. ʻOi aku ka paʻakikī o ke ana ʻana me ka ʻikepili maʻalahi ka waiwai o ka hoʻomaʻemaʻe maʻemaʻe.
Me ka hoʻomohala ʻana o ka ʻenehana ʻenehana i ka ʻoi aku ka maikaʻi a me ka launa ʻana i ke kaiapuni, ke ulu nei ka ʻenehana lining silicon carbide mai ka "palekana kūikawā" i ka "hoʻonohonoho maʻamau". ʻO kēia hoʻonā e hoʻohui i ka ʻepekema waiwai a me ka naʻauao ʻenekinia e pale mālie i ka "laina ola" o ka ʻoihana hou a lilo i kākoʻo ʻenehana koʻikoʻi no ka hoʻomaikaʻi ʻana i ka maikaʻi a me ka pono o nā ʻoihana hana.
