Isostatic graphite, ʻike ʻia hoʻi ʻo ka graphite isostatically formed, pili i kahi ʻano kahi e hoʻopili ʻia ai ka hui ʻana o nā mea maka i loko o nā ʻāpana ʻāpana ʻehā a poepoe paha i loko o kahi ʻōnaehana i kapa ʻia ʻo cold isostatic pressing (CIP). ʻO ka paʻi isostatic anuanu kahi ʻano hana e hoʻololi ai i ke kaomi o kahi wai i hoʻopaʻa ʻia a hiki ʻole ke hoʻololi ʻia i kēlā me kēia ʻāpana o ka wai, me ka ʻili o kāna ipu.
Hoʻohālikelike ʻia me nā ʻenehana ʻē aʻe e like me ka extrusion a me ka vibration forming, CIP technology produces the most isotropic synthetic graphite.Isostatic graphiteloaʻa nō hoʻi ka liʻiliʻi liʻiliʻi o ka graphite synthetic (ma kahi o 20 microns).
Kaʻina hana o ka graphite isostatic
ʻO ke kaomi Isostatic kahi kaʻina hana he nui e hiki ai ke loaʻa nā poloka like ʻole me nā ʻāpana kino mau i kēlā me kēia ʻāpana a me nā kiko.
Nā waiwai maʻamau o ka graphite isostatic:
• Ka wela kiʻekiʻe loa a me ka pale kemika
• Kūleʻa haʻalulu wela maikaʻi
• Kiʻekiʻe uila conductivity
• Kiʻekiʻe thermal conductivity
• Hoʻonui i ka ikaika me ka piʻi ʻana o ka mahana
• maʻalahi e hana
• Hiki ke hana 'ia me ka maemae loa (<5 ppm)
Hana ʻia ographite isostatic
1. Koke
ʻO ka Coke kekahi mea i hana ʻia i loko o nā hale hoʻoheheʻe aila ma ka hoʻomehana ʻana i ka lanahu paʻakikī (600-1200°C). Hana ʻia ke kaʻina hana i loko o nā umu coke i hoʻolālā ʻia me ka hoʻohana ʻana i nā kinoea puhi a me ka hāʻawi ʻana i ka oxygen. He ʻoi aku ka nui o ka calorific waiwai ma mua o ka lanahu fossil maʻamau.
2. Kuʻi ʻana
Ma hope o ka nānā ʻana i ka mea maka, ua ʻoki ʻia i kahi nui o ka ʻāpana. ʻO nā mīkini kūikawā no ka wili ʻana i nā mea e hoʻoili i ka pauka lanahu maikaʻi loa i loaʻa i loko o nā ʻeke kūikawā a hoʻokaʻawale iā lākou e like me ka nui o nā ʻāpana.
Pitch
ʻO kēia ka hopena o ka coking o ka lanahu paʻakikī, ʻo ia hoʻi ka ʻala ʻana ma 1000-1200°C me ka ʻole o ka ea. ʻO Pitch kahi wai ʻeleʻele ʻeleʻele.
3. Kneading
Ma hope o ka pau ʻana o ke kaʻina wili coke, hui ʻia me ka pitch. Hoʻohui ʻia nā mea maka ʻelua i ka wela kiʻekiʻe i hiki ke hoʻoheheʻe ka lanahu a hui pū me nā ʻāpana coke.
4. ʻO ka pulverization ʻelua
Ma hope o ka hui ʻana, hoʻokumu ʻia nā pōpō kalapona liʻiliʻi, pono e hoʻoheheʻe hou ʻia i nā ʻāpana maikaʻi loa.
5. Isostatic kaomi
Ke hoʻomākaukau ʻia nā ʻāpana liʻiliʻi o ka nui i makemake ʻia, e hahai ana ka pae kaomi. Hoʻokomo ʻia ka pauka i loaʻa i loko o nā mole nui, ʻo nā ana e like me ka nui o ka poloka hope. Hōʻike ʻia ka pauka kalapona i loko o ka mold i ke kaomi kiʻekiʻe (ʻoi aku ma mua o 150 MPa), e pili ana i ka ikaika like a me ke kaomi ʻana i nā ʻāpana, e hoʻonohonoho ana iā lākou i ka symmetrically a pēlā e puʻunaue like ʻia. Hiki i kēia ʻano hana ke loaʻa nā ʻāpana graphite like i loko o ka mold.
6. ʻO ka hoʻolāʻau
ʻO ka wā e hiki mai ana a lōʻihi loa (2-3 mau mahina) e hoʻomoʻa ʻia i loko o ka umu. Hoʻokomo ʻia ka mea isostatically i kaomi ʻia i loko o kahi umu nui, kahi e hiki ai ka mahana i 1000 ° C. No ka paleʻana i nā hemahema a iʻole nā māwae, e hoʻomalu mauʻia ka mahana o ka umu. Ma hope o ka pau ʻana o ka kuke ʻana, hiki ka poloka i ka paʻakikī i makemake ʻia.
7. ʻO ka hoʻoheheʻe ʻana o ka pitch
I kēia manawa, hiki ke hoʻopili ʻia ka poloka me ka pitch a puhi hou ʻia e hōʻemi i kona porosity. Hoʻokomo pinepine ʻia ka impregnation me kahi pitch me kahi haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka pitch i hoʻohana ʻia ma ke ʻano he binder. Pono ka viscosity haʻahaʻa e hoʻopiha pono i nā āpau.
8. Kipi
I kēia pae, ua kauoha ʻia ka matrix o nā ʻātoma kalapona a ua kapa ʻia ke kaʻina hoʻololi mai ke kalapona i ka graphite. ʻO ka graphitization ka hoʻomehana ʻana o ka poloka i hana ʻia i kahi mahana ma kahi o 3000 ° C. Ma hope o ka graphitization, hoʻomaikaʻi maikaʻi ʻia ka density, conductivity uila, thermal conductivity a me ka corrosion resistance, a hoʻomaikaʻi pū ʻia ka hana ʻana.
9. Mea Kipi
Ma hope o ka graphitization, pono e nānā ʻia nā waiwai a pau o ka graphite - me ka nui o ka palaoa, ka nui, ka piko a me ka ikaika compressive.
10. Hoʻoponopono
Ke hoʻomākaukau pono a nānā ʻia ka mea, hiki ke hana ʻia e like me nā palapala mea kūʻai aku.
11. Hoomaemae
Inā hoʻohana ʻia ka graphite isostatic i ka semiconductor, ka silika aniani hoʻokahi a me nā ʻoihana ikehu atomic, pono ka maʻemaʻe kiʻekiʻe, no laila pono e hoʻoneʻe ʻia nā mea haumia āpau e nā ʻano kemika. ʻO ka hana maʻamau no ka wehe ʻana i nā haumia graphite ʻo ia ke kau ʻana i ka huahana graphitized i loko o ke kinoea halogen a hoʻomehana iā ia ma kahi o 2000°C.
12. Ka lapaʻau ʻili
Ma muli o ka hoʻohana ʻana o ka graphite, hiki ke hoʻoheheʻe ʻia kona ʻili a loaʻa kahi ʻili maʻalahi.
13. Hoouna
Ma hope o ka hana hope ʻana, hoʻopili ʻia nā kikoʻī graphite i hoʻopau ʻia a hoʻouna ʻia i ka mea kūʻai.
No ka ʻike hou aku e pili ana i nā nui i loaʻa, nā māka graphite isostatic a me nā kumukūʻai, e ʻoluʻolu e kelepona iā mākou. E hauʻoli ko mākou mau ʻenekini e aʻo iā ʻoe i nā mea kūpono a pane i kāu mau nīnau āpau.
