Thuthukisa Amandla Esakhiwo Ngepuleti Ye-Silicon Carbide Eqinile

I-Silicon carbide ingenye yezinto eziqine kakhulu ezitholakalayo ngenkathi isala ingasindi uma kuqhathaniswa, okwenza kube ekahle izicelo zempi Plating.

I-Nitride-bonded silicon carbide ceramic iziqhayisa ukumelana nokukhuphuka okuvelele kanye nokuqina kokuphuka., kanye nokugqwala okuvelele, i-oxidation, futhi ukumelana nokugqoka emazingeni okushisa aphakeme.

Ukuqina

Amapuleti e-silicon carbide’ ukuqina kubenza bakwazi ukumelana nezimo zokusebenza ezinzima ezitholakala ezimbonini nasezindaweni zokugcina izimpahla zanamuhla, okuhlanganisa ukuchayeka emazingeni okushisa aphezulu, ukuwohloka kwamakhemikhali, kanye nokuguga kwemishini. Ukumelana kwazo namazinga okushisa aphezulu, ukuwohloka kwamakhemikhali, futhi ukuguga kwandisa ubude besikhathi semishini ngenkathi kukhulisa ukusebenza.

Ngenxa yezakhiwo zabo eziqinile, izinto ze-ceramic zifaneleka kakhulu ekusetshenzisweni okubandakanya amasondo asikiwe namathuluzi okugaya, izinto eziphikisayo, izingxenye zezimoto, izingxenye ezithwalayo, izingxenye zokushintsha ukushisa kanye nama-ball mill liners. Izinto ze-Ceramic ziziqhenya ngokuqina okuhle kakhulu kokuphuka, Izakhiwo ze-modulus ezisencane namandla aguquguqukayo ezibenza babe ukukhetha okuhle kwezinto ezibonakalayo.

I-Silicon Carbide Crucibles inokusetshenziswa okukhethekile okuningana. Bavame ukuqashwa ezithandweni zokuncibilikisa insimbi, ingilazi annealing amaziko, Izithando zomlilo zokoqweqwe lwawo kanye neziko le-porcelain njengezici ezibalulekile zokubethelwa, esebenza njengama-roller amasilinda embonini ye-ceramic kuyilapho ehlala ekwazi ukumelana nokushaqeka okushisayo, okungase kubangele ubunzima besakhiwo.

Amandla

Amapuleti e-silicon carbide aphakathi kwezinto eziqinile zobuchwepheshe ze-ceramic emakethe. Amandla abo angandiswa ngokuqhubekayo ngokusebenzisa i-microwave sintering, inqubo esungulayo eyehlisa izidingo zamandla kanye namazinga okushisa okusebenza ngokufika ku-1000degC.

I-Material enokuqina okuhle kakhulu kwezinga lokushisa yenza ifaneleke kahle izinhlelo zokusebenza zemvelo ezinokhahlo, kuhlanganise neziphehlisi zenuzi, izinjini zegesi kanye nemishini yokucubungula amakhemikhali. Ihlala iqinile ngisho emazingeni okushisa okusebenza afinyelela ku-1400degC kuyilapho isalokhu ikwazi ukumelana namakhemikhali ukuyivumela ukuthi iqhubeke nokusebenza ezindaweni zokusebenza ezinokhahlo njengalezo ezitholakala ngaphakathi kweziphehlimandla zenuzi., izinjini zegesi kanye nemishini yokucubungula amakhemikhali.

Amapuleti e-silicon carbide aya ngokuya esetshenziswa njengokuvikela imoto yezikhali ngenxa yokuqina kwawo okuyingqayizivele., imvelo engasindi kanye namakhono okuvikela izinsongo eziningi. I-Stanford Advanced Materials (SAM) ungomunye wabahlinzeki abahamba phambili bamapuleti e-SiC ezinhlelo ezinjalo ezibucayi.

Ukuqina

I-Silicon carbide inamandla aphakeme wesakhiwo, ukuqina nokumelana nokugqwala kwamakhemikhali, ukumelana namazinga okushisa okwedlulele kanye nokucindezela okuphezulu ngaphandle kokukhubazeka noma ukukhubazeka ngokuhamba kwesikhathi. Kanjalo, kwenza impahla ekahle yezindawo zezimboni ezijwayele ukugqwala noma amakhemikhali anokhahlo.

Le Ceramic eqinile inezinye izinto eziningi ezihlukile futhi. Yaziwa kakhulu ngokuqina kwayo okukhethekile kokuphuka kanye namagugu e-Young's modulus akhombisa ukumelana nengcindezi nokuqina., kanye ne-thermal conductivity ephezulu kanye namanani e-coefficient yokwandisa okushisayo okuphansi ayenza ifanelekele izinhlelo zokusebenza zezimboni.

Izici ezihlukile ze-Silicon carbide ziyenze yaba into esetshenziswa kabanzi yezikhali zezimoto nezezindiza kanye nezihlangu ze-ballistic kanye nemigoqo., kufaka phakathi izimoto zempi ezifana namathangi kanye nabathwali bezisebenzi ezihlomile ukuze banikeze isivikelo esingcono emlilweni wezikhali ezincane kanye ne-shrapnel.

Ukumelana Nokushisa

Amapuleti e-silicon carbide angakwazi ukumelana namazinga okushisa aphezulu, amakhemikhali nokucindezela ngaphandle kokuphazamisa ubuqotho bawo besakhiwo. Ngaphezu kwalokho, isilinganiso sabo esivelele samandla nesisindo sibavumela ukuthi bavikele abasebenzi kanye nemishini ngokufanayo.

Ukuqina kuzenza ziphelele ezinhlelweni zempi, ngezinto zokuzivikela njengamavesti anamaqhinga, omakalabha nezihlangu ezisetshenziswa ngesikhathi semicimbi ebalulekile njengokuhlenga abathumbi noma ukulawula uthuthuva okuncike kakhulu ezintweni zokuvikela ezifana nalezi ukuze kukhululwe abathumbi noma ukulawula. Ukuqina kwabo okungavamile kubenza bakwazi ukumelana nezinhlamvu noma ezinye izingcezu zesivinini esikhulu ezidutshulwe zibhekiswe kuzo zivela ezinqoleni zesivinini esikhulu..

Izinto ze-amorphous silicon carbide zihlukile kozakwabo abacwebezelayo ngoba ama-athomu ekhabhoni azo asatshalaliswa ngokungahleliwe., engeza amandla nokuqina. Ngaphezu kwalokho, izakhiwo zabo ezincane ezincane zivumela ukushisa kuphele ngokushesha ngenkathi kwandisa ukumelana nokushisa; ukwenza lokhu kube yintandokazi yezisekelo zethreyi le-wafer kanye namapaddles ezithandweni ze-semiconductor.

Ukumelana Kwamakhemikhali

Amapuleti e-Silicon carbide anikeza isivikelo esikhethekile ezindaweni ezinokhahlo ngokumelene nokuhuzuka nokucekelwa phansi, ukuvikela izingxenye ekulimaleni ngokomzimba. Ukusetshenziswa kwazo kuyisihluthulelo kumasistimu abamba amakhemikhali abolayo nezingcindezi kanye nasekufakweni komkhathi nezikhali ezivikelayo..

Le nto yobumba esebenza kahle kakhulu inesinye sezilinganiso zobulukhuni ze-Mohs ezaziwayo, esondela kulena yedayimane. Ngaphezu kwalokho, izimfanelo zayo zihlanganisa amandla avelele, ukwanda okuphansi kokushisa nokumelana nokugqwala kwamakhemikhali.

Lezi zimfanelo zenza i-aluminiyamu ibe yinhle kakhulu ekukhetheni insimbi nokuncibilikisa insimbi, amashalofu eziko kanye nemishini, amasistimu okulawula uketshezi aphatha uketshezi olubolayo noma amagesi, Futha imilomo kanye nemibhobho yokuqhuma njengoba inikeza ukuguguleka okuhle kakhulu nokumelana nokuhuzuka kanye nokumelana ne-oxidation kuqinisekisa ubuqotho besakhiwo sesikhathi eside..
