I-Semicera's Siliconized Graphite – Isixazululo Esisebenza Kakhulu Sezicelo Ezithuthukile

I-Semicera's Siliconized Graphite – Isixazululo Esisebenza Kakhulu Sezicelo Ezithuthukisiwe Isithombe Esifakiwe

Incazelo emfushane:

Zitholele i-graphite ye-Semicera's siliconized, isixazululo esisezingeni eliphezulu esidizayinelwe ukusebenza okuphezulu ezinhlelweni ezithuthukile.Ngenhlanganisela yawo eyingqayizivele ye-silicon ne-graphite, umkhiqizo wethu unikeza ukuguquguquka okushisayo okuhlukile, ukuzinza okuhle kakhulu, nokumelana okuthuthukisiwe kwe-oxidation, okuwenza ube yinketho efanelekile ezimbonini ezifuna ngamandla.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Siliconized graphite iyinhlanganisela yezinto lapho i-silicon carbide ixhunywe khona ebusweni be-graphite substrate.Inezici zokuqina okuphezulu, amandla aphezulu emishini kanye nokumelana nokugqoka kwe-silicon carbide, kanye nezakhiwo zokuzithambisa kanye nokumelana nokushaqeka okushisayo kwegraphite.Kuyimpahla ekahle yokungqubuzana nezinto ezisetshenziswayo zokuvala uphawu, ezifanele ukuvalwa kwemishini kwamaphampu amanzi ahlukahlukene, amaphampu kawoyela, amaphampu amakhemikhali, nama-bearings amaphampu amakhulu anesivinini esikhulu futhi anomthwalo omkhulu.Ngaphezu kwalokho, i-siliconized graphite inokumelana okuhle kwe-oxidation, ukumelana nokushaqeka okushisayo, i-porosity ephansi, kanye nokuhamba okuthile kagesi, futhi ingasetshenziswa njengezinto ezifana nezinsimbi zokuncibilikisa insimbi namashubhu okusalungiswa.

Ukwakheka kwe-siliconizedi-graphite iyunifomu, indawo engaphezulu ihambisana nengaphakathi, futhi isilinganiso sokwakheka kwe-silicon carbide ne-graphite siyalungiseka.Ukuphakama kokuqukethwe kwe-silicon carbide, kukhulu ukuminyana kwezinto, kuyanda amandla okucindezela, futhi ukumelana nokuqina kuyanda.
