Kugadzirwa kwesimba remagetsi ezuva ne photovoltaic kwave indasitiri itsva yesimba inovimbisa zvikuru pasi rose. Kana tichienzanisa ne polysilicon ne amorphous silicon solar cells, monocrystalline silicon, sechinhu chinogadzira simba re photovoltaic, ine simba rekushandura simba re photoelectric uye mabhenefiti akanaka ekutengeserana, uye yave chinhu chikuru chekugadzira simba re solar photovoltaic. Czochralski (CZ) ndeimwe yenzira huru dzekugadzirira monocrystalline silicon. Kuumbwa kweCzochralski monocrystalline furnace kunosanganisira furnace system, vacuum system, gas system, thermal field system uye electrical control system. The thermal field system ndeimwe yenzvimbo dzakakosha pakukura kwe monocrystalline silicon, uye mhando ye monocrystalline silicon inokanganiswa zvakananga nekupararira kwetembiricha ye thermal field.
Zvikamu zvemunda wekupisa zvinonyanya kuumbwa nezvinhu zvekabhoni (zvishandiso zvegrafiti nezvinhu zvekabhoni/kabhoni), izvo zvakakamurwa kuita zvikamu zvekutsigira, zvikamu zvinoshanda, zvinhu zvinodziya, zvikamu zvinodzivirira, zvinhu zvinodzivirira kupisa, nezvimwewo, zvichienderana nemabasa azvo, sezvakaratidzwa muMufananidzo 1. Sezvo saizi ye monocrystalline silicon iri kuramba ichikwira, zvinodiwa zvehukuru hwezvikamu zvemunda wekupisa zviri kuwedzerawo. Zvinhu zvekabhoni/kabhoni zvinova sarudzo yekutanga yezvinhu zvemunda wekupisa zve monocrystalline silicon nekuda kwekugadzikana kwayo uye hunhu hwakanaka hwemakanika.
Mukushanda kweCzochralcian monocrystalline silicon, kunyunguduka kwesilicon zvinhu kuchaita kuti silicon vapor uye silicon splash yakanyungudutswa, zvichikonzera kukanganiswa kwecarbon/carbon thermal field materials, uye hunhu hwemakanika uye hupenyu hwebasa recarbon/carbon thermal field materials zvinokanganiswa zvakanyanya. Saka, nzira yekuderedza kukanganiswa kwesilicon necarbon/carbon thermal field materials uye kuvandudza hupenyu hwavo hwebasa yave imwe yenyaya dzinonyanya kufungwa nevagadziri vesilicon monocrystalline nevagadziri vecarbon/carbon thermal field materials.Kupfeka kwesilicon carbiderave sarudzo yekutanga yekudzivirira pamusoro pezvinhu zvemhepo zvinopisa zvecarbon/carbon nekuda kwekudzivirira kwayo kupisa uye kusakara.
Mupepa rino, kutanga nezvinhu zvinoshandiswa mukugadzira monocrystalline silicon, nzira huru dzekugadzirira, zvakanakira uye zvakaipa zve silicon carbide coating zvinounzwa. Pachikonzero ichi, kushandiswa uye kufambira mberi kwekutsvagisa kwe silicon carbide coating muzvinhu zvinoshandiswa mu carbon/carbon thermal field zvinoongororwa zvichienderana nehunhu hwezvinhu zvinoshandiswa mu carbon/carbon thermal field, uye mazano nemirairo yekuvandudza yekudzivirira pamusoro pezvinhu zvinoshandiswa mu carbon/carbon thermal field zvinopihwa.
1 Tekinoroji yekugadzirirasilicon carbide coating
1.1 Nzira yekuisa zvinhu mubhokisi
Nzira yekuisa zvinhu muzvikamu izvi inowanzo shandiswa kugadzirira silicon carbide yemukati muC/C-sic composite material system. Nzira iyi inotanga yashandisa mixed powder kuputira carbon/carbon composite material, uye yozoipisa pakupisa kwakati. Kutevedzana kwemaitiro akaomarara e physico-chemical kunoitika pakati pemixed powder nepamusoro pemuenzaniso kuti pave ne coating. Zvakanakira zvayo ndezvekuti maitiro acho ari nyore, nzira imwe chete ndiyo inogona kugadzirira dense, isina crack matrix composite materials; Diki size change kubva preform kusvika final product; Yakakodzera chero fiber reinforced structure; Imwe composition gradient inogona kuumbwa pakati pe coating ne substrate, iyo yakanyatsobatanidzwa ne substrate. Zvisinei, kunewo zvimwe zvakaipa, zvakaita se chemical reaction pa high tembiricha, iyo inogona kukuvadza fiber, uye mechanical properties ye carbon/carbon matrix inoderera. Kufanana kwe coating kwakaoma kudzora, nekuda kwezvinhu zvakaita se gravity, izvo zvinoita kuti coating isaenzane.
1.2 Nzira yekuputira slurry
Nzira yekuputira slurry ndeyekusanganisa zvinhu zvekuputira nebinder kuita musanganiswa, wozora zvakaenzana pamusoro pematrix, mushure mekuomeswa mumhepo isina kusimba, sampuli yakaputirwa inopisirwa pakupisa kwakanyanya, uye coating inodiwa inogona kuwanikwa. Zvakanakira ndezvekuti maitiro acho ari nyore uye ari nyore kushandisa, uye ukobvu hwekuputira huri nyore kudzora; Dambudziko nderekuti pane simba rakashata rekubatanidza pakati pekuputira ne substrate, uye kuramba kupisa kwekuputira kwakashata, uye kufanana kwecoating kwakaderera.
1.3 Nzira yekuita kwemakemikari
Nzira yemakemikari yekufema (CVR) inzira yekushanda inobvisa zvinhu zvakasimba zvesilicon kuita silicon vapor patembiricha yakati, uye ipapo silicon vapor inopararira mukati nepamusoro pematrix, uye inopindirana nekabhoni mu matrix kugadzira silicon carbide. Zvakanakira zvayo zvinosanganisira mhepo yakafanana muchoto, mwero wekuita wakafanana uye ukobvu hwezvinhu zvakaputirwa kwese kwese; Maitiro acho ari nyore uye ari nyore kushandisa, uye ukobvu hwekuvhara hunogona kudzorwa nekushandura kumanikidzwa kwesilicon vapor, nguva yekuisa uye zvimwe zviyero. Dambudziko nderekuti sampuro inokanganiswa zvakanyanya nenzvimbo muchoto, uye kumanikidzwa kwesilicon vapor muchoto hakugone kusvika pakuenzana kwedzidziso, zvichikonzera ukobvu hwekuvhara husina kuenzana.
1.4 Nzira yekuisa mhute yemakemikari
Kuisa vapor mumakemikari (CVD) inzira inoshandiswa nemahydrocarbon senzvimbo yegesi uye kuchena kwakanyanya N2/Ar segasi rinotakura zvinhu kuti riise magasi akasanganiswa mu chemical vapor reactor, uye mahydrocarbon acho anoora, anogadzirwa, anoparadzirwa, anonyungudutswa uye anogadziriswa pasi pekupisa kwakati uye kumanikidzwa kuti agadzire mafirimu akasimba pamusoro pezvinhu zvakagadzirwa necarbon/carbon. Zvakanakira ndezvekuti huwandu uye kuchena kwe coating zvinogona kudzorwa; Yakakodzerawo work-piece ine chimiro chakaoma; Chimiro chekristaro uye chimiro chepamusoro chechigadzirwa chinogona kudzorwa nekugadzirisa ma parameter e deposition. Zvakashata ndezvekuti deposition rate yakaderera zvakanyanya, maitiro acho akaomarara, mutengo wekugadzira wakakwira, uye panogona kunge paine zvikanganiso zve coating, zvakaita sekutsemuka, mesh defects uye surface defects.
Muchidimbu, nzira yekuisa zvinhu muzvikamu inogumira pahunhu hwayo hwetekinoroji, iyo yakakodzera kugadzirwa nekugadzirwa kwezvinhu zverabhoritari nezvidiki; Nzira yekuputira haina kukodzera kugadzirwa kwehuwandu nekuda kwekusagadzikana kwayo. Nzira yeCVR inogona kusangana nekugadzirwa kwehuwandu hwezvigadzirwa zvakakura, asi ine zvinodiwa zvakanyanya zvemidziyo netekinoroji. Nzira yeCVD inzira yakanaka yekugadziriraSIC yekuputira, asi mutengo wayo wakakwira kupfuura nzira yeCVR nekuda kwekuoma kwayo mukudzora mashandiro.
