Uma kukhulunywa “ngezinto zobumba”, abantu abaningi baqala ngokucabanga ngezitsha zasekhaya, amavazi okuhlobisa – abuthakathaka futhi athambile, abonakala engahlobene “nemboni” noma “aqinile”. Kodwa kukhona uhlobo lwezinto zobumba oluphula lo mbono ongokwemvelo. Ubulukhuni balo bulandela idayimane kuphela, futhi lungamelana namazinga okushisa aphezulu, lumelane nokugqwala, futhi luphinde lugqunywe futhi luqhutshwe, lube “luguquguqukayo” emkhakheni wezimboni.i-silicon carbide ceramic.
Kusukela emishinini engagugi ezimayini kuya kumamojula kagesi ezimotweni ezintsha zamandla, kusukela ezingxenyeni ezimelana nokushisa okuphezulu ezindiza kuya ezivikelweni zemishini zansuku zonke, izitsha zobumba ze-silicon carbide zisekela buthule ukusebenza kahle kwezimboni eziningi ngezakhiwo zazo ezihlukile. Namuhla, ake sixoxe ngalokho okwenza lesi sitsha sobumba "esingavamile" sivelele.
1、 Kunzima kakhulu: "isithwali" emkhakheni wokumelana nokuguguleka
Inzuzo eyaziwa kakhulu ye-silicon carbide ceramics ubulukhuni bayo obuphezulu kakhulu kanye nokumelana nokuguguleka. Ubulukhuni bayo be-Mohs bungowesibili kuphela kunedayimane elinzima kakhulu emvelweni, buqine kakhulu kunensimbi evamile, insimbi engagqwali, ngisho ne-alumina ceramics.
Lesi sici esiqinile siyenza ikhanye ezimweni lapho idinga ukumelana nokuguguleka. Isibonelo, ezimbonini zezimayini nezensimbi, imishini yokuthutha udaka kanye ne-slag slurry (njengezinjini zokufaka amaphampu e-slurry kanye ne-pipeline liner) ivame ukugezwa yizinhlayiya zamaminerali eziqinile isikhathi eside, kanti izinsimbi ezivamile zizoguguleka ngokushesha futhi zivuze amanzi. Izingxenye ezenziwe nge-silicon carbide ceramics zingamelana kalula nalokhu “kuguguleka” futhi zibe nokuphila kwenkonzo izikhathi eziningana noma ngisho nangaphezu kweshumi kunezingxenye zensimbi, okunciphisa kakhulu imvamisa kanye nezindleko zokushintsha imishini.
Akukhona nje kuphela ezindaweni zezimboni, kodwa singabona nokuba khona kwayo empilweni yansuku zonke – njenge-silicon carbide friction pair ezivalweni zemishini. Ngokumelana kwayo okuhle kakhulu nokuguguleka, iqinisekisa ukuthi imishini ayivuzi futhi inokulahlekelwa okuncane ngesikhathi sokujikeleza ngesivinini esikhulu, okuvumela ukusebenza okuzinzile kwemishini efana namaphampu amanzi nama-compressor.
2, "Ukumelana" Okuphakeme: Ukuvimbela Ukushisa Okuphezulu Nokugqwala
Ngaphezu kobulukhuni, izitsha zobumba ze-silicon carbide nazo zinokumelana okuhle kakhulu nokushisa okuphezulu kanye nokumelana nokugqwala, okuzivumela ukuthi "zinamathele ezigxotsheni zazo" "ezindaweni eziningi ezinzima".
Ngokuphathelene nokumelana nokushisa okuphezulu, ngisho nangemva kokusebenza isikhathi eside ku-1350 ℃, ngeke kube khona ukuthamba noma ukuguquka. Lesi sici siyenza ibe “yisithandwa” embonini yezindiza kanye neyezempi, njengokusetshenziswa njenge-nozzle yezinjini zamarokhethi, ulwelwesi lwezitofu ezishisa kakhulu, njll. Ingathinta ngqo amalangabi ashisa kakhulu noma izinsimbi ezincibilikisiwe ukuze igcine ukuzinza. Ezinqubweni zokukhiqiza ezishisa kakhulu njengezitofu zezimboni kanye nokuphonswa okuqhubekayo kwensimbi, izingxenye ze-silicon carbide ceramic nazo zingathatha indawo yezinsimbi ezonakala kalula amazinga okushisa aphezulu, zandise impilo yemishini.
Ngokuphathelene nokumelana nokugqwala, izitsha zobumba ze-silicon carbide zinamandla amakhulu kakhulu okuqina kwamakhemikhali. Kungakhathaliseki ukuthi ziyi-asidi, i-alkali, noma amagesi ahlukahlukene agqwalisayo kanye noketshezi, kunzima "ukuyigugula". Ngakho-ke, embonini yamakhemikhali, ivame ukusetshenziselwa ukwenza ulwelwesi lwemikhumbi yokusabela, amapayipi kanye nama-valve okuthutha imithombo egqwalisayo; Emkhakheni wokuvikelwa kwemvelo, ukuba khona kwayo kungabonakala nasemishinini yokwelapha amanzi angcolile ane-asidi ephezulu, ukuqinisekisa ukuthi imishini ayigqwali futhi isebenza kahle.
3, “Amakhono” Aguquguqukayo: “Ingcweti Esebenzayo” engaba lukhuni futhi iguquguquke
Uma ucabanga ukuthi izitsha zobumba ze-silicon carbide "ziqinile" futhi "zihlala isikhathi eside" kuphela, khona-ke uzithatha kancane kakhulu. Ngokwezindlela ezahlukene zokucubungula, zingaba nemisebenzi eminingi efana nokuqhuba, ukuvikela ukushisa, kanye nokuqhuba ukushisa, okwenza kube yinto esebenzayo enokusetshenziswa okuningi.
-Izakhiwo zokuqhuba kanye ne-semiconductor: Ngokusebenzisa ezinye izakhi, i-silicon carbide ceramics ingaguquka kusuka kuma-insulator ibe ama-conductor, futhi ibe yizinto ze-semiconductor. Lokhu kuyivumela ukuthi ibonise amakhono ayo emkhakheni wamandla kagesi, njengokwenza amamojula wamandla ezimoto ezintsha zamandla kanye nezingxenye eziyinhloko zama-traction converters ezitimeleni ezihamba ngesivinini esikhulu. Uma kuqhathaniswa nezinto ze-silicon zendabuko, ama-silicon carbide semiconductors anokusebenza kahle kokuqhuba okuphezulu kanye nokusetshenziswa kwamandla okuphansi, okungenza izimoto ezintsha zamandla zishaje ngokushesha futhi zibe nobubanzi obude, futhi kwenze imishini yamandla ibe mincane futhi isebenze kahle kakhulu.
-Ukushisa okuhle kakhulu: Ukushisa kwe-silicon carbide ceramics kudlula kakhulu okokushisa kwe-ceramics okuvamile, futhi kufinyelela ngisho nokwezinsimbi ezithile. Lesi sici sikwenza kube yinto efanelekile yokushabalalisa ukushisa, isibonelo, endaweni yokushabalalisa ukushisa yezibani ze-LED nama-chip kagesi, kungasheshisa ukudlulisa ukushisa, kuvimbele imishini ukuthi yonakale ngenxa yokushisa ngokweqile, futhi kuthuthukise impilo yesevisi kanye nokuzinza.
4, Okokugcina: Izitsha zobumba ze-silicon carbide, 'amandla okushayela angabonakali' okuthuthukisa izimboni
Kusukela “kokuqina nokungagugi” kuya “kokumelana nokugqwala okushisa okuphezulu”, bese kuba “ukusebenza okuningi”, izitsha ze-silicon carbide ziye zaphula ukuqonda kwabantu ngezitsha zendabuko ngochungechunge lwezakhiwo ezinhle kakhulu, zaba yinto ebalulekile esekela ukuthuthukiswa kokukhiqiza okuphezulu, amandla amasha, ukulondolozwa kwamandla kanye nokuvikelwa kwemvelo. Akujwayelekile njengensimbi noma kube lula njengepulasitiki, kodwa ezimweni zezimboni ezidinga “ukunqoba ubunzima”, ihlala ithembele ezicini zayo “ezinamandla onke” ukuze ibe yimbangela eyinhloko yokuxazulula izinkinga.
Ngokuthuthuka okuqhubekayo kobuchwepheshe, izindleko zokukhiqiza izitsha zobumba ze-silicon carbide ziyancipha kancane kancane, futhi izimo zokusetshenziswa nazo ziyanda njalo. Esikhathini esizayo, kokubili imishini yamandla emisha esebenza kahle kakhulu kanye nemishini yezimboni eqinile ingase ibe namandla kakhulu ngenxa yokwengezwa kwezitsha zobumba ze-silicon carbide. Lolu hlobo "lwezinto ezinamandla onke" ezifihliwe embonini lushintsha kancane kancane umkhiqizo wethu kanye nokuphila kwethu.
