Kwihlabathi lemveliso yemizi-mveliso, kusoloko kukho iindawo ezithile ezimile okweemilo ezikhethekileyo ezibangela iintloko zeenjineli - zisenokuba yimibhobho egobileyo kwisixhobo esichanekileyo okanye izakhiwo ezixhasayo ezineemibhobho ezintsonkothileyo kwizixhobo ezishushu kakhulu. Ezi nxalenye, ezaziwa ngokuba “ziinxalenye zasemzini,” zihlala zinzima ukuzenza ngezinto eziqhelekileyo ngenxa yemilo yazo eyahlukileyo kunye neendawo zokusebenza ezinzima. Kule mihla, i-silicon carbide, into ebonakala ingenamsebenzi, itshintsha yonke into kancinci kancinci.
Iingenelo zezinto ezibonakalayo
Ukuqonda isizathui-silicon carbideIyakwazi ukwenza izinto ezingaqhelekanga, kufuneka siqale sijonge "ukwakheka" kwayo. Le nto iqulethe "iijini ezibalaseleyo" ezifunekayo kwimveliso yemizi-mveliso: ubulukhuni bayo bulandela idayimani kuphela, kodwa inokumelana notshintsho olukhulu lobushushu njengesinyithi; Ijongene nokugqwala kwee-asidi ezinamandla kunye ne-alkalis, ihlala inganyakazi; Nokuba kumaqondo obushushu aphezulu akufutshane nomphezulu welanga, isenokugcina imo yayo izinzile.
Olu didi lweempawu luvumele i-silicon carbide ukuba iphumelele kumgca wokuqala ukususela ekuqaleni. Khawuthelekelele ukuba ngelixa ezinye izinto zisasokola ukuba zingenziwa na ngolu hlobo, i-silicon carbide sele icinga ngendlela yokuyenza ibe ngcono. Amandla ayo aphezulu kunye nozinzo kuvumela abayili ukuba baphephe ukutshintsha uyilo lwesakhiwo olufanelekileyo lokuqala ukuze lulungele iipropati zezinto.
'Umlingo wokubumba' oguquguqukayo noguquguqukayo
Ukuba nezinto ezilungileyo zodwa akwanelanga. Ukuguqula i-silicon carbide ibe ziinxalenye ezahlukeneyo ezimile ngendlela engaqhelekanga, kufuneka "umlingo wokubumba" okhethekileyo. Iinjineli kule mihla ziye zafunda iindlela ezahlukeneyo zokwenza i-silicon carbide "ithobele":
Itekhnoloji yokucinezela i-cold isostatic ifana nokubeka "ingubo eqinileyo" ekhethekileyo kwi-silicon carbide powder. Phantsi koxinzelelo oluphezulu, i-powder inokunamathela ngokufanayo kuzo zonke iinkcukacha ze-mold, nokuba yimingxunya enzima kunye neepatheni ezincinci zinokuphinda-phindwa ngokuchanekileyo. Itekhnoloji ye-laser ekhokelwa ngamanzi ifana "nemela yotyando" ethambileyo, isebenzisa ukuhamba kwamanzi ngesantya esiphezulu ukukhokela i-laser kunye nokukrola izakhiwo ezahlukeneyo ezinzima kwi-silicon carbide eqinileyo, engayi kubangela ukuqhekeka kwezinto kwaye inokuqinisekisa ukuba umphezulu uthambile.
Olu phuhliso lwetekhnoloji lukhulule i-silicon carbide kwileyibhile yeeseramikhi zemveli njenge "eqinileyo, enzima, nenzima ukuyicubungula". Njengokubumba ngodongwe ngerabha, ubuchwepheshe bangoku buvumela i-silicon carbide powder ukuba yenze umzimba osondele kwimo yawo yokugqibela, ize emva koko idlule kwi-sintering yobushushu obuphezulu ukuze ibe yimveliso egqityiweyo enzima, nto leyo enciphisa kakhulu ubunzima bokucubungulwa okulandelayo.
Uxanduva Olunokuthenjwa Kwiimeko Ezinzima
Kutheni kufuneka senze umgudu ongaka ekusebenziseni i-silicon carbide ukwenza iindawo ezingahambelaniyo? Kuba amaxesha amaninzi, ezi ndawo zimile ngendlela ekhethekileyo kufuneka zisebenze kwiindawo ezinobungozi.
Kwiketile enamandla ye-acid reaction yesityalo seekhemikhali, umbhobho omile okwe-silicon carbide unokumelana nokugqwala; Kwindawo enobushushu obuphezulu yeenjini zeenqwelo-moya, iibrakethi ezimile okwe-silicon carbide zinokumelana novavanyo lwamawaka eedigri; Kwizixhobo ezichanekileyo zokwenza i-semiconductor, izinto ezimile okwe-silicon carbide zinokugcina ukuchaneka okuzinzileyo. Kwezi meko, imo ekhethekileyo ayenzelwanga ukuba ibukeke intle, kodwa kukufezekisa imisebenzi ethile - isenokuba kukwenza ukuhamba kolwelo kube lula, okanye isenokuba kukususa ubushushu ngokulinganayo.
Ukwahluka kwe-silicon carbide kuxhomekeke ekubeni ikwazi ukuhlangabezana neemfuno zoyilo lwezakhiwo ezingaqhelekanga kunye nokusebenza ngokuthembekileyo kwiindawo ezixineneyo ixesha elide. Olu dibaniso lokuqina kunye nokuguquguquka luye lwenza ukuba ibe yinto ekhethwayo kwiindawo ezininzi zoshishino.
Ikamva lokuvelisa ngokwezifiso
Ngokuhambela phambili kwetekhnoloji yokuvelisa, amandla okwenza ngokwezifiso iindawo ezimile okwe-silicon carbide ahlala ephucuka. Ukusuka kwizakhiwo ezincinci eziziimilimitha ezimbalwa ukuya kwizinto ezinkulu eziziimitha ezininzi ubude, ukusuka ekugobeni okulula ukuya kwi-polyhedra entsonkothileyo, i-silicon carbide iphula ukuqonda kwabantu ngezinto ze-ceramic.
Kumashishini, oku kuthetha amathuba angakumbi okutsha - akusekho mfuneko yokunciphisa izimvo zoyilo lweendawo ezisemgangathweni, kunye nokukwazi ukwenza izisombululo ezifanelekileyo ngokusekelwe kwiimfuno zokwenyani. Kuyo yonke icandelo lemizi-mveliso, ukuthandwa kweendawo ezimile okwe-silicon carbide kuqhuba uphuhliso lwezixhobo ukuya ekusebenzeni okuphezulu, ukuqina, kunye nokuchaneka.
Le nto imangalisayo, “inamandla aqinileyo” kunye “nobugcisa bayo bobuchule”, iguqula uyilo olungaqhelekanga olwalukho kwisicwangciso lube ngamandla asebenzayo aqhuba inkqubela phambili kwezoshishino.
