Kanjani ukwenza amashubhu e-silicon carbide: umhlahlandlela ophelele

I-Silicon Carbide (SIC) iyinto ekhethwayo ezinhlobonhlobo zezicelo zezimboni ngenxa yobulukhuni bayo obuvelele, ukuqina okushisayo, nokumelana kwamakhemikhali. Phakathi kwamafomu alo amaningi, amashubhu e-aillico Carbide abhekwa ngokuqina kwawo kanye nokusebenza ezindaweni ezinokhahlo. Le ndatshana izolungisa inqubo eyinkimbinkimbi yokwenzaAmashubhu e-Silicon Carbide, ukugxila ekukhiqizeni ukusabela - izinkomba ze-silicon Carbide ceramic ceramic.

Ukuqonda Carbito Carbide

Ngaphambi kokuthi singenele kwinqubo yokukhiqiza, kubalulekile ukuqonda ukuthi yiphi i-karicon Carbide. I-Silicon Carbide iyingxenye ye-silicon nekhabhoni eyaziwa ngezakhiwo zayo ezihlukile. Kuyi-semiconductor emelana namazinga okushisa aphezulu, oxidation, nokugqwala. Lezi zakhiwo zenza amashubhu e-silicon Carbide alungele izinhlelo zokusebenza ezimbonini ezinjenge-aerospace, izimoto, kanye nokusebenza kwamakhemikhali.

Ukulungiselela izinto ezingavuthiwe

Isinyathelo sokuqala ekwakheni amashubhu e-silicon Carbide ukulungiselela izinto ezivuthiwe. I-Silicon yekhwalithi ephezulu ye-silicon kanye ne-carbon powder iyizimfanelo zokukhiqiza ukusabela okuphezulu - isobho Carbide (RBSC). Ubumsulwa balawa mapondo bubalulekile; Noma yikuphi ukungcola kuzothinta kakhulu ikhwalithi yomkhiqizo wokugcina. Ngaphezu kwalokho, ukusatshalaliswa kosayizi bezinhlayiyana kwama-powders kumele kulawulwe ngokucophelela. Usayizi ofanayo wezinhlayiyana uqinisekisa ukuthi izinto ezibonakalayo ziphendula ngokulinganayo ngesikhathi senqubo yesono, okuholela kumkhiqizo wokugcina onamandla.

Izithako nokuxubana

Lapho nje izinto eziluhlaza zilungisiwe, isinyathelo esilandelayo siyabhema futhi sixuba. Le nqubo ifaka ukulawula kahle isilinganiso se-silicon powder ku-carbon powder. Isilinganiso esifanele sibalulekile ngoba sinquma ukusabela kwamakhemikhali okuzokwenzeka ngesikhathi sokuthola isono. Ukuxubana kahle amapopi ukuqinisekisa ngisho nokusatshalaliswa kubalulekile ukuze uzuze ukwakheka kwe-silicon carbide okungaguquki. Lesi sinyathelo sibucayi; Noma yikuphi ukungahambelani kwengxube kungaholela ekulimaleni e-silbide Carbide Tube yokugcina yokugcina.

Kwakha ukwakheka kwepayipi

Lapho inqubo yokuhlanganisa nokuxuba iphelele, isinyathelo esilandelayo ukwakheka ipayipi. Lokhu kungatholakala ngezindlela ezahlukahlukene, kufaka phakathi ukucindezela okubandayo okukhona (i-CIP) noma ukukhishwa. I-CIP ibandakanya ukusebenzisa ingcindezi efanayo ye-powder exubile ekufeni, okuholela ekwakhekeni okuhlelekile nokwakheka kahle. Ngenye indlela, ukukhishwa kuvumela ukwakheka okuqhubekayo kokuqukethwe, okuwusizo ikakhulukazi ngokukhiqiza amapayipi amade. Ukukhethwa kwendlela yokubumba kuncike kusayizi oyifunayo kanye nokucaciswa komkhiqizo wokugcina.

Inqubo ye-sonsoring

Inqubo yesono yilapho umlingo wenzeka khona. Ishubhu le-carbide ye-silicon Carbide libekwe esithandweni sokushisa esiphakeme ngejubane elilawulwa ngokushisa kanye nesikhathi sokubamba. Ngalesi sigaba, i-silicon powder kanye ne-carbon powder yasabela ngamakhemikhali ukwakha isakhiwo esiminyene se-silicon carbide. Amazinga okushisa wesono avame phakathi kuka-1400 ° C no-2000 ° C, kuya ngesakhiwo esithile kanye nezakhiwo ezifiselekayo zomkhiqizo wokugcina. Lesi sinyathelo sibalulekile ngoba sinquma amandla omshini nokuqina okushisayo kwe-silicon Carbide Tube.

Ubuchwepheshe bokusebenza ngemuva

Ngemuva kokuthi inqubo yesono iphelele, i-silicon carbide tube isebenza ngemuva. Lesi sigaba sifaka umshini mabhuku kanye ne-surce polishing ukuze sihlangabezane nezidingo zekhwalithi eqondile nezingaphezulu. Ukufakwa ngemishini kungafaka ukusikwa, ukugaya noma ukumba ukufeza ubukhulu obudingekayo, ngenkathi polishing engaphezulu ithuthukisa ama-aesthetics nokusebenza okusebenzayo kwe-tube. Ukusebenza ngemuva kubalulekile ukuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana namazinga wezimboni kanye nokucaciswa kwamakhasimende.

Izindlela zokulawula ezisezingeni eliphakeme

Kuyo yonke inqubo yokukhiqiza, sisebenzisa izindlela zokulawula ezisezingeni lokuqinisekisa ukuthi amashubhu e-silicon Carbide ahlangabezana namazinga adingekayo. Lokhu kufaka phakathi ukuhlola ubumsulwa bezinto zokwakha, ukuqapha ukuguquguquka kwenqubo yokuxuba, nokuhlola ngesikhathi nangemva kokusona. Amasu athuthukile afana nokwehluka kwe-X-RAY nokuskena i-elektroni Microscopy angasetshenziselwa ukuhlaziya ukuhambela kwe-microstructive carbide ukuqinisekisa ukuthi ihlangabezana namazinga okusebenza adingekayo.

Ukusetshenziswa kwe-silicon carbide tube

Amashubhu e-Silicon Carbide asetshenziswa ezinhlobonhlobo zezicelo ngenxa yezakhiwo zazo ezinhle kakhulu. Embonini yokusebenza kwamakhemikhali, zisetshenziselwa ukudlulisa uketshezi olulimazayo, ngenkathi kusemkhakheni we-aerospace, zisetshenziswa njengezakhi ezindaweni ezishisa kakhulu. Ngaphezu kwalokho, amashubhu e-silicon carbide aya ngokuya asetshenziswa kuzinhlelo zokusebenza zamandla, njengezimpendulo zenuzi kanye nama-reaclines wegesi, lapho amandla abo okumelana khona nezimo ezimbi kakhulu zibalulekile.

Ngokufigqiwe

Ukukhiqizwa kwamashubhu e-silicon Carbide amashubhu kuyinqubo eyinkimbinkimbi futhi ebuthakathaka edinga ukunaka ngokucophelela imininingwane ngaso sonke isikhathi. Ukusuka ekuhlelweni kwezinto ezisezingeni eliphakeme zokulawulwa kokulawulwa okuqondile kwenqubo yesono, isinyathelo ngasinye sidlala indima ebalulekile kwikhwalithi yokusebenza komkhiqizo wokugcina. Njengoba izimboni ziyaqhubeka nokufuna izinto ezingamelana nezimo ezinzima, isidingo samashubhu e-silicon Carbide kungenzeka ukuthi sikhule, sikwenze kube okubaluleke kakhulu ukuqonda inqubo yabo yokukhiqiza. Noma ngabe isetshenziselwa izicelo zezimboni noma ukusetshenziswa kwezobuchwepheshe okuthuthukile, amashubhu e-silicon Carbide amele ukuthuthuka okukhulu kwisayensi yezinto zokwakha, ukuhlinzeka ngokuqina nokwethembeka ezindaweni ezahlukahlukene.
