Ezweni lokukhiqiza kwezimboni, kuhlale kunezingxenye ezithile ezibunjwe ngendlela ekhethekile ezibangela onjiniyela ikhanda - zingaba amapayipi agobile ethuluzini elinembile noma izakhiwo zokusekela ezinemifantu eyinkimbinkimbi emishinini eshisa kakhulu. Lezi zingxenye, ezaziwa ngokuthi “izingxenye ezingaziwa,” zivame ukuba nzima ukuzenza ngezinto ezivamile ngenxa yezimo zazo ezihlukile kanye nezimo zokusebenza ezinzima. Namuhla, i-silicon carbide, into ebonakala ingabalulekile, ishintsha yonke into buthule.
Izinzuzo ezingokwemvelo zezinto ngokwazo
Ukuqonda ukuthi kunganii-silicon carbideIyakwazi ukwenza ngezifiso izingxenye ezingajwayelekile, sidinga kuqala ukubheka "ukwakheka kwayo". Le nto ithwala ngokwemvelo "izakhi zofuzo ezinhle kakhulu" ezidingekayo ekukhiqizeni izimboni: ubulukhuni bayo bulandela idayimane kuphela, kodwa ingamelana nezinguquko ezinkulu zokushisa njengensimbi; Ibhekene nokugqwala kwama-asidi aqinile nama-alkali, ihlala inganyakazi; Ngisho noma amazinga okushisa aphezulu eduze kobuso belanga, isengagcina isimo sayo sizinzile.
Lokhu kuhlanganiswa kwezici kwavumela i-silicon carbide ukuthi iwine emgqeni wokuqala kusukela ekuqaleni. Cabanga ukuthi ngenkathi ezinye izinto zisabhekene nobunzima bokuthi zingenziwa yini zibe yilesi simo, i-silicon carbide isivele icabanga ukuthi ingayenza kanjani ibe ngcono. Amandla ayo aphezulu kanye nokuqina kwayo kuvumela abaklami ukuthi bagweme ukushintsha umklamo wokuqala wesakhiwo ofanele ukuze bavumelane nezakhiwo zezinto ezibonakalayo.
'Umlingo wokubumba' oguquguqukayo futhi oguquguqukayo
Ukuba nezinto ezinhle kuphela akwanele. Ukuguqula i-silicon carbide ibe izingxenye ezihlukahlukene ezimile ngendlela engavamile, kudingeka "umlingo wokubumba" okhethekile. Onjiniyela kulezi zinsuku sebenolwazi oluhlukahlukene lokusebenzisa amasu okwenza i-silicon carbide ibe "ilalelayo":
Ubuchwepheshe bokucindezela obuyi-cold isostatic bufana nokufaka "ingubo eqinile" ekhethekile ku-silicon carbide powder. Ngaphansi kokucindezela okuphezulu, i-powder inganamathela ngokulinganayo kuyo yonke imininingwane yesikhunta, ngisho nezimbobo eziyinkimbinkimbi namaphethini amancane angakopishwa ngokunembile. Ubuchwepheshe be-laser obuqondiswa ngamanzi bufana "nommese wokuhlinzwa" obucayi, kusetshenziswa ukugeleza kwamanzi okusheshayo ukuqondisa i-laser nokuqopha izakhiwo ezahlukahlukene eziyinkimbinkimbi ku-silicon carbide eqinile, okungeke kubangele ukuqhekeka kwezinto futhi kungaqinisekisa indawo ebushelelezi.
Lezi zintuthuko zobuchwepheshe zikhulule i-silicon carbide kulebula lezinto zobumba zendabuko njenge "eqinile, eqinile, futhi enzima ukuyicubungula". Njengokubumba ngobumba lwerabha, ubuchwepheshe bamanje buvumela i-silicon carbide powder ukuthi yakhe umzimba oseduze nesimo sayo sokugcina, bese idlula ekushiseni okuphezulu ukuze ibe umkhiqizo oqediwe kanzima, okunciphisa kakhulu ubunzima bokucubungula okulandelayo.
Umthwalo Wemfanelo Othembekile Ezindaweni Ezibucayi
Kungani kufanele senze umzamo omkhulu kangaka ekusebenziseni i-silicon carbide ukwenza izingxenye ezingajwayelekile? Ngoba izikhathi eziningi, lezi zingxenye ezibunjwe ngokukhethekile kufanele zisebenze ezindaweni ezinzima kakhulu.
Eketheni yokusabela kwe-acid enamandla yesitshalo samakhemikhali, ipayipi elinomumo we-silicon carbide lingamelana nokugqwala; Endaweni yokushisa okuphezulu kwezinjini zezindiza, amabhuleki anomumo we-silicon carbide angamelana nokuhlolwa kwezinkulungwane zamadigri; Emishinini yokunemba yokukhiqiza i-semiconductor, izingxenye ezinomumo we-silicon carbide zingagcina ukunemba okuzinzile. Kulezi zimo, ukuma okukhethekile akuhloselwe ukubukeka kahle, kodwa ukufeza imisebenzi ethile - kungaba ukwenza ukugeleza koketshezi kube bushelelezi, noma kungaba ukuqeda ukushisa ngokulinganayo.
Ukuhluka kwe-silicon carbide kusekukwazini kwayo ukuhlangabezana nezidingo zomklamo wezakhiwo ezingajwayelekile nokusebenza ngokwethembeka ezindaweni ezibucayi isikhathi eside. Lokhu kuhlanganiswa kokuqina nokuguquguquka kwenze kwaba yinto ekhethwayo emasimini amaningi ezimboni.
Ikusasa lokukhiqiza okwenziwe ngokwezifiso
Ngokuthuthuka kobuchwepheshe bokukhiqiza, ikhono lokwenza ngokwezifiso izingxenye ezimise okwe-silicon carbide lihlala lithuthuka. Kusukela ezakhiweni ezincane ezingamamilimitha ambalwa kuya ezingxenyeni ezinkulu ezingamamitha amaningana ubude, kusukela ekugobeni okulula kuya kuma-polyhedra ayinkimbinkimbi, i-silicon carbide iphula ukuqonda kwabantu okungokwemvelo ngezinto zobumba.
Kumabhizinisi, lokhu kusho amathuba amasha kakhulu - akusadingeki ukulinganisela imibono yokuklama yezingxenye ezijwayelekile, nokukwazi ukwenza izixazululo ezifanele ngokusekelwe ezidingweni zangempela. Kuwo wonke umkhakha wezimboni, ukuthandwa kwezingxenye ezimise okwe-silicon carbide kuholela ekuthuthukisweni kwemishini ekusebenzeni kahle okuphezulu, ukuqina, kanye nokunemba.
Le nto yomlingo, “ngamandla ayo aqinile” kanye “nobuciko obunekhono”, iguqula imiklamo engajwayelekile eyayikhona epulanini ibe amandla asebenzayo aqhuba intuthuko yezimboni.
