Kwicandelo lemizi-mveliso yanamhlanje, ii-silicon carbide ceramics zaziwa ngokuba “zizixhobo zorhwebo” kwaye ziye zaba zizinto ezibalulekileyo kwiindawo ezixineneyo ngenxa yamandla azo aphezulu, ukumelana nobushushu obuphezulu, kunye nokumelana nokugqwala. Kodwa into abantu abaninzi abangaziyo kukuba usapho lwe-silicon carbide ceramic lunamalungu amaninzi, kwaye iinkqubo ezahlukeneyo zokulungiselela zinika “ubuntu” obahlukileyo. Namhlanje siza kuthetha ngeentlobo eziqhelekileyo zeiiseramikhi zesilicon carbidekwaye ityhila iingenelo ezikhethekileyo ze-reaction sintered silicon carbide, iteknoloji ephambili yamashishini.
1, "Abazalwana abathathu" beSilicon Carbide Ceramics
Ukusebenza kwee-ceramics ze-silicon carbide kuxhomekeke kakhulu kwinkqubo yokulungiselela. Okwangoku kukho iintlobo ezintathu eziphambili:
1. I-silicon carbide engenaxinzelelo
Ngokubumba ngokuthe ngqo umgubo we-silicon carbide ngokusebenzisa i-sintering yobushushu obuphezulu, inobunzima obukhulu kunye nobunzima obuqinileyo, kodwa ubushushu bokulungiselela buphezulu kwaye ixabiso libiza kakhulu, okwenza ukuba ifaneleke kwiindawo ezincinci ezichanekileyo ezineemfuno zokusebenza eziphezulu kakhulu.
2. I-silicon carbide ecinezelweyo eshushu
Yenziwe phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, inesakhiwo esixineneyo kunye nokumelana okuhle kokuguguleka, kodwa izixhobo ziyinkimbinkimbi kwaye kunzima ukuvelisa izinto ezinkulu okanye ezimile ngendlela enzima, nto leyo ethintela uluhlu lwazo lokusetyenziswa.
3. I-Reaction sintered silicon carbide (RBSiC)
Ngokungenisa izinto ze-silicon kwizixhobo ze-silicon carbide kunye nokusebenzisa ii-chemical reactions ukugcwalisa izikhewu zezinto, ubushushu benkqubo buphantsi, umjikelo umfutshane, kwaye iindawo ezinkulu nezingaqhelekanga zinokwenziwa ngokulula. Ukusebenza kakuhle kweendleko kuyamangalisa, okwenza ukuba ibe lolona hlobo lwe-silicon carbide olusetyenziswa kakhulu kwicandelo lemizi-mveliso.
2, Kutheni i-reaction sintered silicon carbide ithandwa ngakumbi?
Njengemveliso ephambili yeshishini, inkqubo eyahlukileyo ye-reaction sintered silicon carbide (RBSiC) yenza ukuba ibe "yinto ekhethwayo" kumashishini amaninzi. Iingenelo zayo zingashwankathelwa ngamagama amathathu angundoqo:
1. Yomelele kwaye ihlala ixesha elide
Inkqubo yokusila i-reaction yenza "isakhiwo esidibeneyo" ngaphakathi kwezinto, esinokumelana namaqondo obushushu aphezulu angama-1350 ℃ kwaye sinokumelana nokuguguleka okugqwesileyo kunye nokumelana namaqondo obushushu aphezulu - akonakalanga lula kwiindawo eziguguleka kakhulu kunye neendawo ezishushu kakhulu, ngakumbi ezifanelekileyo kwiimeko zobushushu obuphezulu ezifana nezixhobo ze-oven kunye nezitshisi.
2. Yiya edabini ngezixhobo ezikhanyayo
Xa kuthelekiswa nezinto zesinyithi zemveli, i-reaction sintered silicon carbide inoxinano oluphantsi kodwa inokubonelela ngenqanaba elifanayo lamandla, nto leyo enciphisa kakhulu ukusetyenziswa kwamandla kwezixhobo. Umzekelo, kwishishini le-photovoltaic, izinto ze-silicon carbide ezikhaphukhaphu zinokuphucula kakhulu ukusebenza kakuhle kwee-single crystal furnaces.
3. Iguquguqukayo kwaye iguquguqukayo
Nokuba ziitreyi ze-semiconductor ezinobubanzi obungaphezulu kweemitha ezi-2, ii-nozzles ezintsonkothileyo, iiringi zokutywina, okanye iindawo ezimile ngendlela eyenzelwe wena ezineemilo ezahlukeneyo, iteknoloji yokusabela ingakwazi ukulawula ngokuchanekileyo imo kunye nobukhulu, isombulule ingxaki yokuvelisa "enkulu nechanekileyo".
3, 'Amandla angabonakaliyo okuqhuba' okuphucula amashishini
"Umfanekiso" we-reactive sintered silicon carbide ungene kwiindawo ezininzi, ukusuka kwiireyili zesikhokelo ezingakhukulisekiyo kwii-oven ze-metallurgical ukuya kwiipayipi ezingakhukulisekiyo kwizixhobo zeekhemikhali. Ukubakho kwayo akupheleli nje ekwandiseni ubomi bezixhobo, kodwa kukwanceda amashishini ukuba afezekise ukonga amandla kunye nokunciphisa ukusetyenziswa - umzekelo, kwicandelo le-oven yemizi-mveliso, ukusetyenziswa kwefenitshala ye-oven ye-silicon carbide kunokunciphisa kakhulu ukulahleka kobushushu.
Isiphelo
'Ubuchule' bee-carbide ceramics budlula le nto. Njengovulindlela kwitekhnoloji ye-reaction sintering, sihlala siphucula inkqubo ukuze siphucule ixabiso lale nto kwiindawo ezixineneyo. Ukuba ujonge izisombululo zoshishino ezimelana nobushushu, ezimelana neempembelelo, nezihlala ixesha elide, unokufuna ukunaka amathuba amaninzi ee-silicon carbide ceramics!
I-Shandong Zhongpeng ibigxile kuphando kunye nokuveliswa kwe-reaction sintered silicon carbide kangangeminyaka engaphezu kweshumi, inika izisombululo ze-ceramic ezenzelwe abathengi behlabathi.
