Mu mafakitale amakono, zipangizo zogwira ntchito bwino, zosawononga chilengedwe, komanso zolimba zikuyamikiridwa kwambiri. Zida zadothi zopangidwa ndi silicon carbide, monga zinthu zoboola kwambiri, zikuchita gawo lofunika kwambiri m'magawo monga kusefa kutentha kwambiri, kuteteza chilengedwe, komanso uinjiniya wamankhwala wolondola chifukwa cha ubwino wawo wapadera wogwirira ntchito.
1, Kodi silicon carbide microporous ceramic ndi chiyani?
Silikoni kabide (SiC)ndi chinthu chopangidwa ndi silicon ndi carbon, chomwe chili ndi kuuma kwakukulu, kukana kutentha kwambiri, komanso kukana dzimbiri, ndipo chimadziwika kuti "diamondi ya mafakitale". Zipangizo zadothi zazing'ono zokhala ndi mapokoso ndi zinthu zodzazidwa ndi mapokoso ang'onoang'ono mkati, zomwe zimawapatsa mphamvu zabwino kwambiri zosefera, kulowetsedwa, komanso kupuma.
Zida za silicon carbide zokhala ndi mipopo yopyapyala zimaphatikiza makhalidwe abwino kwambiri a silicon carbide ndi mawonekedwe a mipopo yopyapyala, zomwe zimatha kusunga bata m'malo ovuta kwambiri ndikupanga kusefa bwino ndi kulekanitsa mpweya kapena zakumwa, zomwe zimapangitsa kuti zikhale chida chogwiritsidwa ntchito m'mafakitale.
2, N’chifukwa chiyani zinthu zoumba za silicon carbide microporous zimakonda kwambiri?
1. Kukana kutentha kwambiri, kokhazikika ngati mwala
Zipangizo zambiri zimatha kusinthika kapena kulephera kutentha kwambiri, pomwe silicon carbide microporous ceramics imatha kugwira ntchito mokhazikika m'malo opitilira 1200 ℃ kwa nthawi yayitali popanda kusokoneza magwiridwe antchito awo chifukwa cha kutentha kwambiri. Izi zimapangitsa kuti ikhale chisankho chabwino kwambiri chochizira mpweya wotentha kwambiri m'mafakitale monga zitsulo ndi magetsi.
2. Kusefa kolondola komanso kulekanitsa bwino
Mwa kuwongolera bwino kukula kwa ma micropores, ma ceramics a silicon carbide microporous amatha kuletsa tinthu tating'onoting'ono komanso zinthu zomwe zili mu molekyulu. Pakupanga mankhwala, imatha kulekanitsa bwino ma catalyst; Pankhani yoteteza chilengedwe, imatha kutenga fumbi loipa mu mpweya wotayira wa mafakitale ndikuthandizira kupanga zobiriwira.
3. Yolimba ndipo imachepetsa ndalama zokonzera
Zinthu za silicon carbide zokha zimakhala ndi mphamvu yolimba kwambiri yopewera kuwonongeka komanso kukana kutentha kwambiri. Ngakhale m'malo ozizira komanso otentha kwambiri, zinthu za silicon carbide zomwe zimakhala ndi pobowola pang'ono zimatha kukhalabe zokhazikika, kuchepetsa kwambiri kuchuluka kwa zida zomwe zimayikidwa m'malo mwake komanso kuchepetsa ndalama zogwirira ntchito m'mabizinesi.
3, zochitika zogwiritsira ntchito za silicon carbide microporous ceramics
Kuyeretsa mpweya wotentha kwambiri: monga kusungunula zitsulo, kutentha zinyalala, ndi zina zotero, kumatha kugwira bwino tinthu tating'onoting'ono mu mpweya wotentha kwambiri ndikubwezeretsa mphamvu ya kutentha.
Mankhwala olondola komanso okonza zinthu: Monga chonyamulira zinthu, chimathandiza kuti zinthu zigwire bwino ntchito ndipo chimatha kupirira malo ovuta monga ma asidi amphamvu ndi maziko.
Pankhani ya mphamvu zatsopano, thandizo lokhazikika la kufalikira kwa mpweya limaperekedwa mu njira monga kukonzekera mphamvu ya haidrojeni ndi kuwotcha zinthu za batri.
Kusamalira madzi m'malo ozungulira: Kudzera mu kusintha pamwamba, angagwiritsidwe ntchito posamalira madzi otayira ndi mafuta, kusakaniza ndi zitsulo zolemera, ndi zina zotero, kuti athandize kupanga madzi oyera.
4, malangizo a chitukuko chamtsogolo
Ndi kupita patsogolo kwa ukadaulo wamafakitale komanso kufunikira kowonjezereka kwa chitetezo cha chilengedwe, ziwiya za silicon carbide microporous zikukula kuti zikhale zolondola kwambiri komanso zanzeru. Mwachitsanzo, kukulitsa magwiridwe antchito ake kudzera muukadaulo wopaka utoto wophatikizika, kapena kuziphatikiza ndi njira zanzeru zowunikira kuti zikwaniritse kuwongolera nthawi yeniyeni. M'tsogolomu, zikuyembekezeka kuonekera bwino m'magawo apamwamba monga ma semiconductors ndi biomedicine.
mapeto
Ngakhale kuti zinthu zopangidwa ndi silicon carbide microporous ceramics zingawoneke ngati zachilendo, zimagwira ntchito yofunika kwambiri popanga mafakitale komanso kuteteza chilengedwe. Zimateteza mwakachetechete ukhondo ndi magwiridwe antchito a mafakitale ndi magwiridwe antchito okhazikika, mphamvu zosefera bwino, komanso kulimba kwa nthawi yayitali. M'tsogolomu, ndi luso lopitilira laukadaulo, lipitiliza kuthandizira pakukweza mafakitale ndi chitukuko chobiriwira.
