I-Semixlab Glassy carbon coated graphite substrate

I-Glassy carbon coated graphite substrate iyinhlanganisela yezinto ezine-graphite njengesisekelo, efakwe noma embozwe ngekhabhoni eyingilazi, ehlanganisa ukusebenza kahle kakhulu nokumelana nokushisa okuphezulu kwegraphite nokungabi namandla kwamakhemikhali aphezulu, ukuminyana nezici ezibushelelezi zekhabhoni eyingilazi.

Ukuze kuhlangatshezwane nezidingo ezithuthukayo zemboni, senze iphothifoliyo yemikhiqizo ehlukahlukene ehlome ngokugcwele ukuhlangabezana nezidingo zobuchwepheshe bokuhlanganisa isizukulwane esilandelayo, siqinisekisa ukuthi singanikeza izixazululo ezihambisana nentuthuko yakamuva emkhakheni we-semiconductor.

Isicelo:

Ngokombono wezinkambu zohlelo lokusebenza, uhla lokusetshenziswa kwe-graphite enengilazi ehlanganiswe nekhabhoni lubanzi kakhulu. Emkhakheni wezinto zokwakha ze-semiconductor, ngenxa yokumelana kwayo okuhle kakhulu nokushisa okuphezulu, ukumelana ne-oxidation kanye ne-conductivity, isibe yimpahla ekahle yokukhiqiza amabhodi esekethe adidiyelwe asebenza kahle kakhulu kanye nemishini kagesi. Emkhakheni wezinto eziqhubekayo zokuphonsa, i-graphite ye-glassy carbon coated isetshenziswa kakhulu ku-crystallizer ulwelwesi lwemishini yokuphonsa eqhubekayo ngenxa yokugcoba kwayo okuhle nokumelana nokushisa okuphezulu, ukuthuthukisa ngokuphumelelayo ukusebenza kahle okuqhubekayo kokuphonsa kanye nekhwalithi ye-ingot. Ngaphezu kwalokho, emkhakheni we-aerospace, imboni yenuzi, i-metallurgy, imboni yamakhemikhali, njll., i-glassy carbon camera graphite nayo idlala indima engenakushintshwa.

Amasevisi anganikezwa:

Ukuhlaziywa kwesimo sohlelo lwekhasimende, izinto ezifanayo, ukuxazulula izinkinga zobuchwepheshe.

Iphrofayela Yenkampani:

I-Semixlab inamalabhorethri angu-2, ithimba lochwepheshe abaneminyaka engu-20 yokuhlangenwe nakho okubalulekile, abane-R&D kanye nokukhiqiza, amakhono okuhlola nokuqinisekisa.

Imininingwane Quick:

a. isicelo esiyinhloko: Ama-substrates e-Glassy carbon coated graphite anezinhlobonhlobo zokusetshenziswa emikhakheni ehlukahlukene njengama-semiconductors, amandla, ubuchwepheshe bokuhlanganisa okukhethekile kanye nobuchwepheshe obusafufusa ngenxa yezakhiwo zabo ezihlukile zomzimba namakhemikhali. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ububanzi bokusebenza nokubaluleka kwayo kulindeleke ukuthi kukhule ngokuqhubekayo.

b. Inqubo yokulungiselela:

Inqubo yokumboza:

I-graphite substrate icwiliswa kusixazululo se-carbonizable polymer precursor futhi i-uniform coating yenziwa nge-spin coating, i-spray coating noma i-chemical vapor deposition (CVD).

I-carbonization yezinga lokushisa eliphezulu:

Ukwelashwa kwezinga lokushisa eliphezulu (1000–3000°C) endaweni engasebenzi (njenge-argon) kuguqula i-polymer ibe ikhabhoni eyingilazi, eboshwe ngokuqinile ku-graphite substrate.

c. Amapharamitha wokucaciswa okubalulekile:

ukujiya kokunamathela (okukhethwe ngokwendawo egqwalayo, enogqinsi oluyi-50-100μm); i-substrate graphite density (ukuminyana okuphezulu ukumelana nokungena); umkhathi wokusetshenziswa (i-oxidizing/inert); Izinga lokushisa ≤10℃/min (yehlisa ingcindezi esibonakalayo); Ukusebenzisa izinga lokushisa emoyeni ≤600℃ (ukuvikelwa kwegesi engenzi lutho kuyadingeka uma kudlula)

Iziqhathaniso zokusebenza ezibalulekile

Izinkambu zohlelo lokusebenza eziyinhloko

Ukuqinisekiswa kochungechunge lwezemvelo

Kuphasiswe ukuqinisekiswa kokwethembeka ngabakhiqizi abafana ne-Sinosteel
Inkampani kanye neFangDa.

Inqubo yokukhiqiza ejwayelekile

Khetha i-substrate (impahla yegraphite ene-porosity engu-10% -15%) → Ukuhlanza indawo (1000-2000 rpm/min, 30-60min) nokushisa kuqala (150-200 ℃, 1-2h) → Ukulungiswa kwesixazululo se-phenolic resin(200-500, viscos-minity) 30min/min 500-1000mpa·s) → Ukwelashwa kwe-Dip(30-50℃, 2-4h, ingcindezi: 5-10mpa) → Ukwelashwa kwezinga lokushisa eliphansi(150-200℃, 2-4h) → Ukwelashwa kwe-Carbonization(1000℃, 1-2h, 0.01mpatha izinga lokushisa → Igrafu ephezulu/iminithi ℄) 2500℃)

Ngokuthuthuka okuqhubekayo kwezobuchwepheshe kanye nokuthuthukiswa komkhiqizo, i-Semixlab's glassy carbon coated graphite substrate izuze impumelelo ezintweni ezifuywayo zegraphite, yahlangabezana nesidingo esikhulayo se-glassy carbon coated graphite emikhakheni esezingeni eliphezulu njengezimoto ezintsha zamandla, izinhlelo zokugcina amandla, nezinto zokwakha ze-semiconductor. Uma udinga ukuthola imininingwane eminingi ngamaphepha amhlophe obuchwepheshe noma uhlele ukuhlolwa kwesampula, sicela uxhumane nethimba lethu losekelo lobuchwepheshe.
