ʻO nā ʻōkuhi nui ʻekolu o ke koho ʻana i ka graphite semiconductor

ʻO ka ʻoihana semiconductor kahi ʻoihana ʻepekema a me ka ʻenehana e kū mai ana, kahi i huki nui ʻia ai ka manaʻo i nā makahiki i hala iho nei, ua hoʻomaka ka nui o nā ʻoihana e komo i ka ʻoihana semiconductor, a ua lilo ka graphite i hoʻokahi o nā mea pono ʻole no ka hoʻomohala ʻana i ka ʻoihana semiconductor. Pono nā Semiconductors e hoʻohana i ka conductivity uila o ka graphite, no ka mea, ʻo ke kiʻekiʻe o ka ʻike kalapona o ka graphite, ʻoi aku ka maikaʻi o ka conductivity uila, pono e noʻonoʻo i nā ʻōkuhi: ka nui o ka ʻāpana, ke kūpaʻa wela, ka maʻemaʻe.

Pili ka nui o ka palaoa i nā helu mesh like ʻole, a ua hōʻike ʻia nā kikoʻī ma nā helu mesh. ʻO ka helu mesh ka helu o nā lua, ʻo ia hoʻi, ka helu o nā lua i kēlā me kēia ʻīniha kuea. Ma ke ʻano laulā, ʻo ka helu mesh * aperture (micron) =15000. ʻO ka nui o ka helu mesh o ka graphite conductive, ʻo ka liʻiliʻi o ka nui o ka ʻāpana, ʻoi aku ka maikaʻi o ka hana lubrication, hiki ke hoʻohana ʻia ma ke kahua o ka hana ʻana i nā mea lubricating. Pono e lahilahi loa ka nui o ka ʻāpana i hoʻohana ʻia ma ka ʻoihana semiconductor, no ka mea, ʻoi aku ka maʻalahi o ka hoʻokō ʻana i ka pololei o ka hana ʻana, ka ikaika compressive kiʻekiʻe, a me ka pohō liʻiliʻi, ʻoi aku hoʻi no nā ʻōmole sintering, e koi ana i ka pololei o ka hana ʻana.

Ka hoʻolaha ʻana o ka nui o nā ʻāpana, e like me: 20 mesh, 40 mesh, 80 mesh, 100 mesh, 200 mesh, 320 mesh, 500 mesh, 800 mesh, 1200 mesh, 2000 mesh, 3000 mesh, 5000 mesh, 8000 mesh, 12500 mesh, ʻo ka mea liʻiliʻi loa he 15,000 mesh.

Pono e hoʻomehana mau ʻia nā huahana he nui i ka ʻoihana semiconductor, i mea e hoʻolōʻihi ai i ke ola lawelawe o ka hāmeʻa, ka mea e pono ai ka graphite conductive e loaʻa nā waiwai penei: ka hilinaʻi maikaʻi loa a me ke kūpaʻa ʻana i ka hopena wela kiʻekiʻe.

ʻO nā koi no ka hana ʻana o ka graphite i ka ʻoihana semiconductor: ʻo ke kiʻekiʻe o ka maʻemaʻe, ʻoi aku ka maikaʻi, ʻoiai nā mea graphite e pili ana ma waena o nā mea ʻelua, inā he nui nā haumia i loko o lākou, e haumia lākou i ka mea semiconductor. No laila, pono mākou e kāohi pono i ka maʻemaʻe o ka graphite conductive, a pono hoʻi mākou e mālama iā lākou me ka graphitization wela kiʻekiʻe i mea e hōʻemi ai i ka pae hina.
