Pehea e hiki ai i ka graphite ke hoʻololi i ke keleawe ma ke ʻano he electrode?Kaʻana like ʻia eKiʻekiʻe mechanical ikaika Graphite Electrode Kina.
I ka makahiki 1960, ua hoʻohana nui ʻia ke keleawe e like me ka mea electrode, me ka helu hoʻohana ʻana ma kahi o 90% a me ka graphite ma kahi o 10%.I ke kenekulia 21, ua hoʻomaka ka nui o nā mea hoʻohana e koho i ka graphite e like me ka mea electrode.Ma ʻEulopa, ʻoi aku ma mua o 90% o nā mea electrode he graphite.ʻO ke keleawe, ʻo ia ka mea nui o ka electrode material, ua aneane nalowale kona lihi ma luna o ka graphite.He aha ke kumu o kēia hoʻololi nui?ʻOiaʻiʻo, nui nā pono o ka electrode graphite.
(1) ʻoi aku ka wikiwiki o ka hana ʻana: ma ke ʻano nui, ka wikiwiki o ka mīkini hanaKūʻai aku ʻo Graphite Electrodehiki ke 2 ~ 5 manawa wikiwiki ma mua o ke keleawe;Eia naʻe, ʻoi aku ka wikiwiki o ka edm ma mua o ke keleawe, a ʻoi aku ka liʻiliʻi o ka mea i ka deformation.ʻO ka wahi palupalu o ke keleawe ma kahi o 1000 degere, a he maʻalahi ke hoʻololi ʻia e ka wela.Graphite sublimation wela o 3650 degere;ʻO ka coefficient o ka hoʻonui wela he 1/30 wale nō o ke keleawe.
(2) ʻoi aku ka māmā: ʻo ka nui o ka graphite he 1/5 wale nō ia o ke keleawe, hiki ke hoʻemi pono i ke kaumaha o ka mīkini mīkini (EDM) i ka wā e hana ʻia ai nā electrodes nui e ka hoʻokuʻu ʻana;ʻOi aku ka maikaʻi no ka hoʻohana ʻana i ka mold nui.
(3) ʻoi aku ka liʻiliʻi o ka hoʻopau ʻana;No ka mea, aia i loko o ka ʻaila hinu nā ʻātoma C, i ka wā o ka hoʻokuʻu ʻana, ʻo ka wela kiʻekiʻe e hoʻoheheʻe ʻia nā ʻātoma C i loko o ka ʻaila hinuhinu, kahi e hana ai i kahi kiʻiʻoniʻoni pale ma ka ʻili o ka electrode graphite, e uku ana i ka nalowale o ka electrode graphite. .
(4) ʻaʻohe burrs;Ma hope o ka hana ʻana o ka electrode keleawe, pono e ʻoki ʻia me ka lima e wehe i nā burrs, aʻo ka graphite e hana ʻia e kahale hana graphite electrodeme ka ʻole burrs, ka mea e mālama ai i ka nui o nā kumukūʻai a maʻalahi i ka hoʻomaʻamaʻa ʻana i ka hana
(5) ʻoi aku ka maʻalahi o ka graphite i ka wili a me ka poli;No ka mea ʻo ka graphite he hapalima wale nō o ka ʻoki ʻana o ke keleawe, ʻoi aku ka maʻalahi o ka wili ʻana a me ka poli me ka lima.
(6) kumu kūʻai haʻahaʻa haʻahaʻa a me ke kumu kūʻai paʻa;Ma muli o ka piʻi ʻana o ke kumukūʻai keleawe i nā makahiki i hala iho nei, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka graphite isotropic ma mua o ke keleawe.Ma lalo o ka leo like, ʻo ke kumu kūʻai o nā huahana graphite maʻamau o ka toyo carbon he 30% ~ 60% haʻahaʻa ma mua o ke keleawe, a ʻoi aku ka paʻa o ke kumukūʻai, ʻoi aku ka liʻiliʻi o ke kumukūʻai pōkole.
Ma muli o kēia pono hiki ʻole ke hoʻohālikelike ʻia, ua hoʻololi mālie ka graphite i ke keleawe e like me ka mea i makemake ʻia no ka electrode EDM.
