ʻO nā hōʻailona nui ʻekolu o ke koho graphite semiconductor

ʻO kaʻoihana semiconductor kahiʻoihanaʻepekema a me kaʻenehanaʻenehana e ulu nei, kahi i hoʻokipa nui i nā makahiki i hala iho nei, ua hoʻomaka ka nui o nā hui e komo i kaʻoihana semiconductor, a ua lilo ka graphite i kekahi o nā mea waiwai nui no ka hoʻomohalaʻana i kaʻoihana semiconductor. Pono nā Semiconductors e hoʻohana i ka conductivity uila o ka graphite, no ka mea, ʻoi aku ka kiʻekiʻe o ka carbon content o ka graphite, ʻoi aku ka maikaʻi o ka conductivity uila, maʻamau pono e noʻonoʻo i nā mea hōʻailona: ka nui o ka ʻāpana, ka pale wela, ka maʻemaʻe.

Pili ka nui o ka palaoa i nā helu mesh like ʻole, a hōʻike ʻia nā kikoʻī i nā helu mesh. ʻO ka helu mesh ka helu o nā puka, ʻo ia ka helu o nā puka ma ka ʻīniha huinahā. Ma ka ʻōlelo maʻamau, helu mesh * aperture (micron) =15000. ʻO ka nui o ka helu mesh o ka graphite conductive, ʻoi aku ka liʻiliʻi o ka nui o ka ʻāpana, ʻoi aku ka maikaʻi o ka hana lubrication, hiki ke hoʻohana ʻia i ke kahua o ka hana ʻana i nā mea lubricating. Pono maikaʻi ka nui o ka ʻāpana i hoʻohana ʻia i ka ʻoihana semiconductor, no ka mea ʻoi aku ka maʻalahi o ka hoʻokō ʻana i ka pololei o ka hoʻoponopono ʻana, ka ikaika compressive kiʻekiʻe, a me ka liʻiliʻi liʻiliʻi, ʻoi aku hoʻi no ka sintering molds, e koi ana i ka pololei kaʻina hana kiʻekiʻe.

ʻO ka mahele 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, 8012 mesh ʻoi aku ka maikaʻi loa 15,000 mesh.

Nui nā huahana i loko o ka ʻoihana semiconductor pono e hoʻomau ʻia i ka wela, i mea e hoʻonui ai i ke ola lawelawe o ka hāmeʻa, e koi ana i ka graphite conductive e loaʻa i kēia mau waiwai: hilinaʻi maikaʻi loa a me ke kūpaʻa hopena kiʻekiʻe.

ʻO nā koi no ka hana graphite i ka ʻoihana semiconductor: ʻoi aku ka kiʻekiʻe o ka maʻemaʻe, ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi o nā mea graphite e hoʻopā ai ma waena o nā mea ʻelua, inā he nui nā haumia, e hoʻohaumia lākou i nā mea semiconductor. No laila, pono mākou e hoʻomalu pono i ka maʻemaʻe o ka graphite conductive, a pono mākou e mālama iā lākou me ka graphitization wela kiʻekiʻe i mea e hōʻemi ai i ka pae hina.
