I-Green Silicon Carbide Micropowder: Inkanyezi Ekhulayo Yeziphazamiso Ezisebenza Kakhulu
Namuhla, ake siqhubeke nengxoxo yethu ngomunye umdlali onamandla emndenini ohlukumezayo—i-micropowder eluhlaza ye-silicon carbide. Labo bethu embonini ngasese bayibiza ngokuthi “iHulk,” futhi abacabangi ukuthi leli gama liyinqaba; amakhono ayo ahambisana ngempela nalelo gama. Muva nje sixoxe kabanzi nge-alumina emhlophe exutshwe kahle; ifana nengcweti yasenkantolo ecophelelayo, ekhiqiza umsebenzi omuhle nohlanzekile. Kodwa “iHulk” yanamuhla ifana kakhulu nojenene we-vanguard ohlasela empini, ogxile ezimpini ezinzima futhi ebhekana nezinselele ezinzima kakhulu. Kungani ibizwa ngokuthi “inkanyezi ephumayo”? Isizathu sokuqala “ubulukhuni” bayo.
I-silicon carbide eluhlaza inamandla okuqina okuphezulu kakhulu phakathi kwe-abrasives evamile, enobunzima be-Mohs obungu-9.5, obuphansi kancane kunedayimane. Ungawuthathi kalula lo mehluko ongu-0.5 ngaphezulu.i-alumina emhlophe ehlanganisiwe; lapho kusetshenzwa ngezinto ezithile eziqinile, kwenza umehluko omkhulu. Izinto ezintsha zihlala zivela: i-silicon carbide ceramics, i-aluminium nitride, ingilazi ye-sapphire, ama-wafer e-silicon e-photovoltaic, i-carbide eqinisiwe—nganye inzima kuneyokugcina. Ukusebenzisa izinto ezivamile zokukhuhla kufana nokuklwebha itshe ngeshidi lensimbi—kuyakhandla futhi akusebenzi.
Kodwa nge-silicon carbide micropowder eluhlaza, ilungile impela. Imiphetho yayo ecacile nebukhali isebenza njengamathuluzi amancane okusika idayimane, "ihlafuna" ngempumelelo lezi zinto ezinzima. Ikakhulukazi embonini ye-photovoltaic, ukusika lawo ma-ingot e-silicon aqinile futhi aqhekekayo e-monocrystalline kanye ne-polycrystalline, uzobona ukuthi isetshenziswa engxenyeni enkulu yemigqa yokukhiqiza. Ngaphandle kwayo, izindleko kanye nokusebenza kahle kokukhiqiza bekungeke kuncishiswe. Yilokhu okubiza ngokuthi "into eyodwa inqoba enye."
Ngaphezu kwalokho, ukuhanjiswa kwayo kokushisa kuhle kakhulu.
Le nto ngokwayo iyisiqhubi sokushisa esihle kakhulu. Lokhu kuyinzuzo enkulu ezinqubweni zokugaya. Cabanga nje, ukugaya okusheshayo kukhiqiza ukushisa okukhulu ngokushesha. Uma lokhu kushisa kungakwazi ukunyamalala bese kubhajwa ngaphakathi kwento yokusebenza, kuyinhlekelele: ubuso bento yokusebenza buyashesha “ukusha” nokuqhekeka; izingxenye zensimbi zingase zinciphe, zishintshe ubulukhuni bazo; futhi ubukhulu bezingxenye ezinembile bungase bungabi bunembile ngenxa yokwanda nokuncipha kokushisa.
I-micropowder ye-silicon carbide eluhlaza isebenza njenge-"uhlelo lokusabalalisa ukushisa okuncane" olwakhelwe ngaphakathi, oluhambisa ukushisa ngokushesha kude nendawo yokugaya, lunciphisa ngempumelelo izinga lokushisa lendawo yokucubungula. Lokhu kunciphisa umonakalo womsebenzi obangelwa ukushisa ngokweqile, okuqinisekisa ikhwalithi yokucubungula. Lokhu cishe kuyisici esibalulekile, ikakhulukazi ezintweni zokwakha nezingxenye ezizwela kakhulu ekushiseni.
Ngaphezu kwalokho, isici sayo “sokuzilola” sigcina umsebenzi ubukhali njalo.
Izinto zokubhula ezinhle aziwona umkhiqizo "owenziwa kanye kuphela"; kudingeka zihlale isikhathi eside.izinhlayiya ze-silicon carbide eziluhlazaziqinile futhi ziyaphuka, ngaphansi kwamandla okugaya, izinhlayiya ezifiphele zizophuka, zidalule imiphetho emisha, ebukhali ukuze ziqhubeke nokusebenza. Lesi sici sibizwa ngokuthi “ukuzilola.”
Lokhu kufana nokusebenzisa ipensela yomshini; uma iba buthuntu, uyayicindezela futhi, bese kuvela ipensela entsha ukuze iqhubeke nokudweba. Lokhu kusho ukuthi kuyo yonke inqubo yokucubungula, ikhono layo lokusika lihlala lisha futhi linamandla, ngaphandle kokuba buthuntu ngokuhamba kwesikhathi. Ukusebenza kahle kokucubungula kuzinzile, futhi ikhwalithi yobuso bomsebenzi iyafana, kugwema isimo lapho ikhwalithi ithuthuka ekuqaleni kodwa yonakale kamuva. Lokhu kubalulekile ekukhiqizweni kwesimanje, okukhulu, okuzenzakalelayo.
Ake ngikuxoxele indaba eyiqiniso.
Ngonyaka odlule, imboni eyenza ama-nozzle enjini asebenza kahle yangithinta. Ama-nozzle abo enziwe ngobumba obukhethekile obunobulukhuni obukhulu kakhulu. Ukusebenzisa ama-abrasives avamile ekucubunguleni kwakungasebenzi kahle futhi kubiza kakhulu, noma ikhwalithi yobuso yayingaphansi kwezinga, ivame ukukhombisa imifantu emincane. Kamuva, bazama ukusebenzisa i-green silicon carbide micropowder yokugaya nokupholisha kahle, futhi imiphumela yaba ngokushesha. Akuzange nje kuphela ukuthi ukusebenza kahle kwanda ngo-30-40%, kodwa okubaluleke kakhulu, ngaphansi kwe-microscope, ungqimba lomonakalo ebusweni be-workpiece lwalucishe lungabonakali, futhi izinga lokukhiqiza landa kakhulu. Umphathi wabo kamuva wakhala, “Kubonakala sengathi umsebenzi wawungenzima; asikhethanga imishini efanele.”
Uyabona, yilawo amandla “kaHulk”—emkhakheni wayo wobuchwepheshe, ingaxazulula izinkinga abanye abangakwazi ukuzixazulula.
Yiqiniso, le "vanguard general" ayinazo izici zayo ezingavamile. Nakuba iqinile, ukuqina kwayo kuphansi, okwenza iqine kancane. Ngakho-ke, lapho isebenza ngezinto ezithile eziqinile, njengezinsimbi ezithile, ingase ingasebenzi kahle njenge-alumina emhlophe ehlanganisiwe eqinile. Ngaphezu kwalokho, umbala wayo oluhlaza okwesibhakabhaka uvela enanini elincane lokungcola; ezinqubweni ezithile zokupholisha ze-semiconductor ezidinga ubumsulwa obukhulu bamakhemikhali, ngisho nezinto ezihlanzekile zingadingeka. Kodwa lokhu akunciphisi isikhundla sayo sokubusa ekucutshungulweni kwezinto eziqinile nezibuthakathaka.
Ngakho-ke kungani kubhekwa “njengenkanyezi ekhulayo”? Bheka nje izitayela zamanje nezesikhathi esizayo embonini: ama-semiconductor esizukulwane sesithathu (i-silicon carbide, i-gallium nitride), amandla amasha e-photovoltaic, izinto zobumba zezindiza, ingilazi ebonakalayo ephezulu… eziningi zalezi zimboni zokuphuma kwelanga zithembele ezintweni zokucubungula eziyinhloko eziqinile futhi ezibuthakathaka. I-micropowder ye-silicon carbide eluhlaza ingenye yamathuluzi afaneleka kakhulu futhi asebenzayo okubhekana nalezi zinkinga eziyinselele.
Amandla ayo akhula kanye nalezi zimboni zobuchwepheshe obuphezulu. Uma nje lezi zimboni zisathuthuka, kuzoba nesidingo esiqhubekayo se-micropowder eluhlaza ye-silicon carbide esebenza kahle kakhulu. Imboni yethu yokuhudula i-abrasive nayo icwaninga njalo ukuthi ingenza kanjani izinhlayiya zayo zifane kakhulu kanye nokuphathwa kwayo kobuso kube ngcono, ukuze ikhanye kakhulu kulesi sikhathi esithembisayo.
