Kwigumbi elicocekileyo lefektri ye-semiconductor, ii-wafers ezimnyama ezikhazimlayo nge-metallic luster zicutshungulwa ngokuchanekileyo nganye nganye; Kwigumbi lokutsha lenjini ye-spacecraft, icandelo elikhethekileyo le-ceramic libhaptizwa ngomlilo we-2000 ℃. Emva kwezi ziganeko, kukho into esebenzayo ebizwa ngokuba yi-"ilitye elimnyama le-industrial" -iiseramikhi zesilicon carbide.
Le nto iqinileyo, ilandela idayimani kuphela ngobunzima, ibhala ngokutsha imithetho yokwenziwa kwezinto eziphezulu ngokuzolileyo. Iyakwazi ukumelana nemitha enamandla yee-reactor zenyukliya, idlulise ngokukhawuleza amandla ombane akhulayo ezithuthi ezintsha zamandla, kwaye ibe yinto ephambili yokusasaza ubushushu kwizikhululo zesiseko ze-5G. Kodwa emva kokusebenza okugqwesileyo kangaka, kukho umngeni ongenakuphikiswa: indlela yokuthomalalisa le nto "ingalawulekiyo"?
Iipropati zezinto ezibonakalayo zichonga imingeni yokucubungula
Ubunzima bokucubungula i-silicon carbide bufana neepateni zokuqopha kwiglasi. Ubunzima bayo buphindwe kathathu ukuya kahlanu kunobo be-ceramics eziqhelekileyo. Izixhobo zokusika eziqhelekileyo zifana nokuqopha iipleyiti zentsimbi ngetshokhwe, ezingapheleli nje ekubeni nokusebenza okuphantsi kodwa neziqhekeza umphezulu owenziwe ngomatshini ngokulula. Okunzima nangakumbi kukuba le nto ibuthathaka ngokucacileyo, kwaye impazamo encinci inokuyiqhekeza njengebhisikithi, ngakumbi kwiindawo ezichanekileyo ezinobukhulu obungaphantsi kwe-1 millimeter, inkqubo yokucubungula ingachazwa njengokudanisa kwintambo yentsimbi.
Indlela Yokuphumelela Kwemveliso Yanamhlanje
Njengoko bejongene nale mingeni, iinjineli ziye zaphuhlisa “iindlela ezintathu eziphambili zokuthambisa izinto”:
1. Itekhnoloji yokubumba i-mold – inkqubo yokucinezela eshushu efana nokwenza ii-mooncakes, evumela i-silicon carbide powder ukuba "ivumelane ngokuthobela" phantsi kobushushu obuphezulu kunye noxinzelelo, okwenza ukuba ifaneleke ngakumbi ekuveliseni izixhobo zokusika zoshishino ezisemgangathweni. Le teknoloji ifana nokubeka ii-mold shackles kwizixhobo, ukubumba iimilo zejometri eziqhelekileyo phantsi kolawulo lobushushu oluchanekileyo.
2. Indlela yokusika ulwelo – kusetyenziswa iteknoloji yokubumba ngenaliti, ulusu lwezinto lufakwa kwi-mold efana ne-chocolate sauce, kwaye ngolawulo oluchanekileyo lwendlela yokuhamba, izakhiwo ezintsonkothileyo ezingenanto ziyabunjwa. Le ndlela yenza kube nokwenzeka ukuvelisa ii-nozzles ezingaqhelekanga zee-thrusters zesathelayithi.
3. Iteknoloji yokwakha kwakhona umgubo – kusetyenziswa iteknoloji yokunyibilikisa umgubo ukwakha kwakhona ulwakhiwo lwezixhobo ezifana neebhloko zokwakha, ukudala izitywino ze-reactor zenyukliya ezidibanisa amandla kunye nokuchaneka. Le nkqubo ivumela izixhobo ukuba "zitshintshe" kwinqanaba leemolekyuli, zifezekise ukuphuculwa okujoliswe kuko ekusebenzeni.
Iinkcukacha eziphambili zomatshini wokuchwetheza ngokuchanekileyo
Ukuze ukwazi kakuhle oku, akufuneki izixhobo eziphambili kuphela, kodwa kufuneka nemithetho emithathu yegolide: uyilo oluchanekileyo lwesikhunta, ukujonga inkqubo ngononophelo, kunye nonyango oluqinileyo lwezinto ngaphambi kokuba zisetyenziswe. I-Shandong Zhongpeng ilandela ngokungqongqo le mithetho mithathu kwinkqubo yemveliso, izama ukuqinisekisa umgangatho kunye nobungakanani. Ayifuni nje kuphela ukonyuka kwexabiso lemveliso egqityiweyo, kodwa ikwafuna ukuba iimveliso ezigqityiweyo zihlangabezane neemfuno zabathengi ngokungqongqo.
Okwangoku, ngokusebenzisa ubuchwepheshe obutsha obufana nokucubungula nge-laser kunye nokusika nge-ultrasonic, ii-silicon carbide ceramics zigqobhoza imiqobo yokugqibela yokucubungula. Ezi mpumelelo azivumeli nje kuphela "amatye anqabileyo amnyama" ukuba ahambe ngokwenene ukuya kwimizi-mveliso, kodwa zikwabonisa ukufika komjikelo omtsha woguquko lwezinto eziphathekayo.
Kwiinkampani zemveliso ezifuna impumelelo kwezobuchwepheshe, ukucubungula i-silicon carbide ngumceli mngeni kunye nethuba. Ukukhetha amaqabane okucubungula anamava amaninzi kunye neenkqubo ezintsha kuya kuba sisitshixo segolide sokuvula ucango lokuvelisa olukumgangatho ophezulu. Le nto, eyayikade ithathwa 'njengengxaki yokucubungula', ilinde amaqhawe amaninzi ukuba atyhile imfihlakalo yayo yokugqibela.
