Njenge “qhawe elingashiwongo” lokudluliswa kwamandla emkhakheni wezimboni,izishintshi zokushisaukusekela buthule ukusebenza kwezimboni ezifana namakhemikhali, amandla, kanye ne-metallurgy. Kusukela ekupholiseni kwesimo somoya kuya ekupholiseni kwenjini yerokhethi, ubukhona bayo bugcwele yonke indawo. Kodwa-ke, ngemuva kokudlulisa ukushisa okubonakala kulula, ukukhethwa kwezinto ngokuvamile kuba yisihluthulelo sokunquma impumelelo noma ukwehluleka kwemishini. Namuhla sizodalula ikhodi ewumnyombo yezishintshisi zokushisa futhi sifunde ukuthi izitsha zobumba ze-silicon carbide ziletha kanjani emisha kulo mkhakha.
1. Izinhlobo ezihlukahlukene zokushintshanisa ukushisa
Izishintshi zokushisa zihlukaniswa kakhulu zibe izigaba ezine ngokusekelwe ezicini zazo zesakhiwo:
1. Uhlobo lwegobolondo neshubhu - umklamo wamapayipi anezendlalelo eziningi ofana nonodoli ovalelwe, lapho imidiya yangaphakathi nengaphandle idlulisela ukushisa ngokungaqondile ngodonga lwamapayipi, okulungele izimo zokucindezela okukhulu nezinga lokushisa eliphezulu;
2. Uhlobo lwepuleti - olwakhiwe ngezingcwecwe zensimbi eziboshelwe eziteshini ze-maze, isakhiwo sepuleti elincane sivumela ukudluliswa kokushisa okusebenzayo "okungaphezulu kuya phezulu" koketshezi olushisayo nolubandayo;
3. Uhlobo lwe-Fin - amaphiko ensimbi akhula ebusweni bepayipi ukuze kwandiswe indawo engaphezulu futhi kuthuthukiswe ukusebenza kahle kokudlulisa ukushisa komoya;
4. I-Spiral - Khipha umzila wokugeleza ube yisimo sentwasahlobo ukuze unwebe isikhathi sokuxhumana se-medium endaweni elinganiselwe.
Sonke isakhiwo sikugeyimu enezici ezibonakalayo zezinto ezibonakalayo: isibonelo, izinto zensimbi ezivamile, nakuba ziqhuba ukushisa ngokushesha, zivame ukuveza ukushiyeka ngaphansi kwezimo ezimbi kakhulu njengokugqwala namazinga okushisa aphezulu.
2, Inguquko Yezinto ezibonakalayo: Ukuphumelela Kwezinto Zobumba zeSilicon Carbide
Njengoba onjiniyela beqhubeka nokwandisa ukwakheka kwezishintshi zokushisa, ukuvela kwe-silicon carbide ceramics kusheshise lokhu kuguquguquka. Le nto yobumba eqine kakhulu ehlanganiswe ngokuzenzisa ibhala kabusha imithetho yegeyimu emkhakheni wokushintshaniswa kokushisa:
1. I-Corrosion Terminator
Ukugqwala kwamakhemikhali okufana ne-asidi eqinile nesifutho sikasawoti kufana "nesitha semvelo" sezinsimbi, kuyilapho izitsha zobumba ze-silicon carbide zinokumelana nokugqwala okuphezulu kakhulu. Ekukhiqizeni amakhemikhali, impilo yabo yesevisi ingafinyelela izikhathi eziningana kuneyendabuko yensimbi engagqwali, futhi imijikelezo yokugcinwa kwemishini inwetshwa kakhulu.
2. Shisisa umzila osheshayo
Nakuba ibizwa nge-ceramic, ukuqhutshwa kwayo okushisayo kuqhathaniswa ne-aluminium alloy. Isakhiwo sekristalu esiyingqayizivele sivumela ukushisa ukuthi kuphakame njengomgwaqo onguthelawayeka, ngokusebenza kahle kokudlulisa ukushisa okuphindwe izikhathi eziningana kunobumba obuvamile, okuyenza ifaneleke ngokukhethekile izinhlelo zokulawula izinga lokushisa ezidinga ukusabela okusheshayo.
3. Ukushisa okuphezulu kwe-fighter
Ingakwazi ukugcina ukuqina kwesakhiwo ngisho nasezingeni eliphezulu lokushisa elingu-1350 ℃, okwenza ingakwazi ukubuyiseleka emikhakheni ekhethekile njengokushiswa kukadoti kanye ne-aerospace. Izinto zensimbi sezivele zithambekile futhi zonakele kule ndawo, kepha i-silicon carbide ihlala iqinile.
4. Ukukhanya futhi kulula ukukuthwala
Uma kuqhathaniswa nemishini yensimbi emikhulu, izitsha zobumba ze-silicon carbide zinokuminyana okuphansi. Le nzuzo "engasindi" ibaluleke kakhulu kumadivayisi eselula kanye nezimo zokusebenza ezisezingeni eliphezulu, ezinciphisa ngokuqondile izindleko zokuhamba nezokufaka.
3, Ikusasa lilapha: Izinto ezintsha ziqhuba ukuthuthukiswa kwezimboni
Ngomongo wokungathathi hlangothi kwekhabhoni, okokusebenza kwezimboni kunezidingo eziqinile ngokuya ngokusebenza kahle kwamandla. Izishintshi zokushisa ze-silicon carbide ze-ceramic azinciphisi nje kuphela ukulahlekelwa amandla okubangelwa ukugqwala nokukalwa, kodwa futhi zinesikhathi eside sokuphila esinciphisa udoti wensiza obangelwa ukushintshwa kwemishini emthonjeni. Njengamanje, lobu buchwepheshe busetshenziswe ngempumelelo emikhakheni yamandla emisha efana nokulungiswa kwe-silicon ye-photovoltaic polycrystalline kanye ne-sintering yebhethri ye-lithium, okubonisa ukuguquguquka okuqinile kwemingcele.
Njengomsunguli obambe iqhaza ngokujulile ocwaningweni nasekuthuthukisweni kwezitsha zobumba ze-silicon carbide, siqhubeka ngokugqashuka izithiyo zobuchwepheshe zokwakheka kwezinto kanye nokwenza kahle machining. Ngokwenza ngokwezifiso imikhiqizo ene-porosity ehlukene nezici ezingaphezulu, lobu' ubuchwepheshe obumnyama 'bungahlangabezana ngempela nezidingo ezikhethekile zezimboni ezihlukahlukene. Lapho izishintshisi zokushisa zendabuko zihlangabezana nezingqinamba zokusebenza, izinto zobumba ze-silicon carbide zingenisa inkathi entsha yokudlulisa ukushisa okusebenzayo.
Umlando wokuziphendukela kwemvelo wobuchwepheshe bokushintshanisa ukushisa empeleni uwumlando wokuqamba izinto ezintsha. Ukusuka kunsimbi ecijile kuye ku-titanium alloy, ukusuka ku-graphite kuye ku-silicon carbide, ukuguqulwa kwezinto ezibonakalayo ngakunye kuletha ukuthuthuka okuthe xaxa ekusebenzeni kahle kwamandla. Ukukhetha i-silicon carbide ceramics akukhona nje ngokukhetha izingxenye zemishini ezinokwethenjelwa, kodwa futhi mayelana nokukhetha izixazululo ezizinzile zezimboni zesikhathi esizayo.
