Kwintsimi yemizi-mveliso yanamhlanje, ii-silicon carbide ceramics zaziwa ngokuba "sisikrweqe semizi-mveliso" kwaye ziye zaba sesona sixhobo siphambili kwiimeko ezigqithisileyo ngenxa yamandla azo aphezulu, ukumelana nobushushu obuphezulu, kunye nokumelana nokugqwala. Kodwa into abantu abaninzi abangayaziyo yeyokuba usapho lwesilicon carbide ceramic eneneni lunamalungu amaninzi, kwaye iinkqubo ezahlukeneyo zamalungiselelo zibanika “ubuntu” obukhethekileyo. Namhlanje siza kuthetha ngeentlobo eziqhelekileyo zei-silicon carbide ceramicskwaye utyhile izibonelelo ezizodwa zokusabela kwi-silicon carbide, itekhnoloji engundoqo yamashishini.
1, "Abazalwana Abathathu" beSilicon Carbide Ceramics
Ukusebenza kwe-silicon carbide ceramics ubukhulu becala kuxhomekeke kwinkqubo yayo yokulungiselela. Ngoku kukho iintlobo ezintathu eziphambili:
1. Non uxinzelelo sintered silicon carbide
Ngokubumba ngokuthe ngqo i-silicon carbide powder ngokusebenzisa i-high-temperature sintering, inoxinano oluphezulu kunye nokuqina olomeleleyo, kodwa ubushushu bokulungiselela buphezulu kwaye ixabiso liyabiza, okwenza ukuba lilungele amacandelo amancinci achanekileyo kunye neemfuno eziphezulu kakhulu zokusebenza.
2. Isilicon carbide ecinezelweyo eshushu
Yakhelwe phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, inesakhiwo esixineneyo kunye nokumelana nokunxiba okugqwesileyo, kodwa izixhobo zintsonkothile kwaye kunzima ukuvelisa izinto ezinobungakanani obukhulu okanye obuntsonkothileyo, zinciphisa usetyenziso lwazo.
3. I-Reaction sintered silicon carbide (RBSiC)
Ngokuzisa izinto ze-silicon kwi-silicon carbide izinto ezikrwada kunye nokusebenzisa iikhemikhali zokuphendula ukuzalisa izikhewu zezinto, ubushushu benkqubo buphantsi, umjikelo mfutshane, kwaye iindawo ezinobungakanani obukhulu kunye nezingaqhelekanga zinokuvezwa ngokuguquguqukayo. Ukusebenza kweendleko kubalaseleyo, okwenza kube lolona hlobo lusetyenziswa kakhulu lwe-silicon carbide kwindawo yoshishino.
2, Kutheni i-react sintered silicon carbide ithandwa ngakumbi?
Njengemveliso engundoqo yeshishini, inkqubo ekhethekileyo yokuphendula i-silicon carbide (RBSiC) iyenza ibe "yeyona nto ikhethwayo" kumashishini amaninzi. Izibonelelo zayo zinokushwankathelwa ngamagama angundoqo amathathu:
1. Yomelele kwaye ihlala ixesha elide
Inkqubo ye-reaction sintering yakha "isakhiwo esidibeneyo" ngaphakathi kwezinto eziphathekayo, ezinokumelana nokushisa okuphezulu kwe-1350 ℃ kwaye inokumelana nokunxiba okugqwesileyo kunye nokumelana nokushisa okuphezulu-angonakaliswa lula kwiindawo eziphezulu zokunxiba kunye neendawo zokushisa eziphezulu, ezilungele iimeko eziphezulu zokushisa ezifana nezixhobo ze-oven kunye nezitshisi.
2. Yiya edabini ngezixhobo zokukhanya
Xa kuthelekiswa nezinto zentsimbi zemveli, i-react sintered silicon carbide inoxinano olusezantsi kodwa inokubonelela ngenqanaba lamandla afanayo, inciphisa kakhulu ukusetyenziswa kwamandla kwezixhobo. Ngokomzekelo, kwishishini le-photovoltaic, i-silicon lightweight carbide components inokuphucula ngokubonakalayo ukusebenza kakuhle kwee-furnaces ze-crystal enye.
3. Iguquguquka kwaye iguquguquka
Nokuba ziitreyi ze-semiconductor ezinobubanzi obungaphezulu kweemitha ezi-2, imilomo entsonkothileyo, imisesane yokutywina, okanye iindawo ezibunjiweyo ezenziwe ngokwezifiso ezinemilo eyahlukeneyo, itekhnoloji ye-reaction sintering inokulawula ngokuchanekileyo imilo kunye nobukhulu, ukusombulula ingxaki yokuvelisa "enkulu kwaye ichanekile".
3, 'Amandla okuqhuba angabonakaliyo' ophuculo lwemizi-mveliso
"Umzobo" we-action sintered silicon carbide uye wangena kwiindawo ezininzi, ukusuka kwisikhokelo esixhathisa ukhukuliseko kwiziko lesinyithi ukuya kwimibhobho ekwaziyo ukudleka kwizixhobo zekhemikhali. Ubukho bayo abunandisi nje kuphela ixesha lokuphila kwezixhobo, kodwa kwakhona kunceda amashishini afezekise ukugcinwa kwamandla kunye nokunciphisa ukusetyenziswa - umzekelo, kwintsimi ye-industrial kilns, ukusetyenziswa kwefenitshala ye-silicon carbide kiln kunokunciphisa kakhulu ukulahleka kobushushu.
Ukuqukumbela
'Ubuchule' beekeramics ze-carbide buhamba ngaphaya koku. Njengovulindlela kwitekhnoloji ye-reaction sintering, siqhuba ngokuqhubekayo inkqubo yokwandisa ixabiso lesi sixhobo kwiimeko ezigqithisileyo. Ukuba ujonge izisombululo zemizi-mveliso ezikwaziyo ukumelana nobushushu, ukumelana neempembelelo, kwaye ezinobomi obude, unokufuna ukunikela ingqalelo kumathuba amaninzi e-silicon carbide ceramics!
I-Shandong Zhongpeng ibigxile kuphando kunye nemveliso ye-action sintered silicon carbide iminyaka engaphezu kweshumi, ibonelela ngezisombululo ze-ceramic ezilungiselelwe abathengi behlabathi.
