Igraphite eIsostatic, ekwaziwa ngokuba yi-isostatically form graphite, ibhekisa kwindlela apho umxube wemathiriyeli ekrwada uxinaniswe ube ziibhloko ezixande okanye ezingqukuva kwinkqubo ebizwa ngokubanda kwe-isostatic pressing (CIP). I-Cold isostatic pressing yindlela yokucubungula izinto apho utshintsho kuxinzelelo lwe-conduction, incompressible fluid luhanjiswa ngokungaguqukiyo kuyo yonke indawo yolwelo, kubandakanywa nomphezulu wesitya sayo.
Xa kuthelekiswa nobunye ubuchule obunje nge-extrusion kunye nokwenziwa kokungcangcazela, itekhnoloji yeCIP ivelisa eyona isotropic synthetic graphite.Igraphite eIsostatickananjalo idla ngokuba neyona sayizi incinci yeenkozo kuyo nayiphi na igraphite eyenziweyo (malunga ne-20 microns).
Inkqubo yokwenziwa kwegraphite ye-isostatic
Ukucinezela kwe-Isostatic yinkqubo enamanqanaba amaninzi evumela ukufumana iibhloko ezifanayo ngokugqithisileyo ezineeparamitha zomzimba ezingaguqukiyo kuyo yonke indawo kunye nendawo.
Iimpawu eziqhelekileyo zegraphite ye-isostatic:
• Ubushushu obuphezulu kakhulu kunye nokumelana neekhemikhali
• Ukuxhathisa ukothuka kwe-thermal
• Ukuhanjiswa kombane okuphezulu
• High conductivity thermal
• Yandisa amandla ngokunyuka kwamaqondo obushushu
• Kulula ukusetyenzwa
• Inokuveliswa ngokucoceka okuphezulu kakhulu (<5 ppm)
Ukwenziwa kweigraphite ye-isostatic
1. ikokhi
I-Coke yinxalenye eveliswa kwiindawo zokucoca ioli ngokufudumeza amalahle aqinileyo (600-1200 ° C). Inkqubo iqhutyelwa kwii-ovens ze-coke ezenziwe ngokukodwa ngokusebenzisa iigesi ezivuthayo kunye nokunikezelwa kwe-oksijini encinci. Inexabiso eliphezulu le calorific kunamalahle efosili eqhelekileyo.
2. Ukutyumza
Emva kokutshekisha i-raw material, ichithwa kwi-particle ethile. Oomatshini abakhethekileyo bokugaya izinto eziphathekayo badlulisa umgubo ocolekileyo kakhulu wamalahle ofunyenwe kwiingxowa ezikhethekileyo kwaye uhlele ngokobukhulu bamasuntswana.
I-pitch
Le yimveliso ephumayo yokuphekwa kwamalahle aqinileyo, oko kukuthi ukugcadwa kwi-1000-1200 ° C ngaphandle komoya. I-pitch lulwelo olumnyama olushinyeneyo.
3. Ukuxova
Emva kokuba inkqubo yokugaya i-coke igqityiwe, ixutywa ne-pitch. Zombini izinto eziluhlaza zixutywe kwiqondo lokushisa eliphezulu ukwenzela ukuba amalahle anyibilike kwaye adibanise kunye neengqungquthela zecoke.
4. I-pulverization yesibini
Emva kwenkqubo yokuxuba, iibhola ezincinci zekhabhoni zenziwe, ekufuneka zihlanjwe kwakhona kwiincinci ezintle kakhulu.
5. Ukucinezela isostatic
Emva kokuba kulungiswe amaqhekeza amancinci obungakanani obufunekayo, inqanaba lokucinezela liyalandela. Ipowder efunyenweyo ifakwe kwiimbumba ezinkulu, imilinganiselo ehambelana nobukhulu bokugqibela bebhloko. I-carbon powder kwi-mold ibonakaliswe kuxinzelelo oluphezulu (ngaphezulu kwe-MPa ye-150), esebenzisa amandla afanayo kunye noxinzelelo kwiinqununu, ukuzicwangcisa ngokulinganayo kwaye ngaloo ndlela zihanjiswe ngokulinganayo. Le ndlela ivumela ukufumana iiparamitha ezifanayo zegraphite kulo lonke isikhunta.
6. Carbonization
Inqanaba elilandelayo nelide kakhulu (iinyanga ezi-2-3) libhaka kwisithando somlilo. Izinto ezicinezelweyo ze-isostatically zifakwe kwisithando somlilo esikhulu, apho ubushushu bufikelela kwi-1000 ° C. Ukuze ugweme naziphi na iziphene okanye ukuqhekeka, iqondo lokushisa kwisithando somlilo lihlala lilawulwa. Emva kokugqitywa kokubhaka, ibhloko ifikelela kubunzima obufunekayo.
7. I-Pitch Impregnation
Kweli nqanaba, ibhloko inokufakwa kwi-pitch kwaye itshiswe kwakhona ukunciphisa i-porosity yayo. I-impregnation idla ngokuqhutywa nge-pitch ene-viscosity esezantsi kune-pitch esetyenziswa njengesibophelelo. I-viscosity ephantsi iyadingeka ukuze ugcwalise izithuba ngokuchanekileyo.
8. Ukuzoba
Kweli nqanaba, i-matrix ye-athomu ye-carbon iye yacwangciswa kwaye inkqubo yokuguqulwa kwekhabhoni ukuya kwigraphite ibizwa ngokuba yi-graphitization. IGraphitization kukufudumeza ibhloko eveliswayo ukuya kubushushu obumalunga ne-3000°C. Emva kwegraphitization, ukuxinana, ukuhanjiswa kombane, ukuhanjiswa kwe-thermal kunye nokumelana nokubola kuphuculwe kakhulu, kunye nokusebenza kakuhle kuphuculwe.
9. Izinto zegraphite
Emva kwegraphitization, zonke iipropathi zegraphite kufuneka zihlolwe - kubandakanywa ubungakanani beenkozo, ubuninzi, ukugoba kunye namandla oxinzelelo.
10. Ukulungiswa
Emva kokuba izinto zilungiswe ngokupheleleyo kwaye zitshekishwe, zingenziwa ngokwamaxwebhu abathengi.
11. Ukuhlanjululwa
Ukuba i-graphite ye-isostatic isetyenziswe kwi-semiconductor, i-silicon eyodwa ye-crystal kunye namashishini anamandla e-athomu, ukucoceka okuphezulu kuyadingeka, ngoko ke zonke izinto ezingcolileyo kufuneka zisuswe ngeendlela zamachiza. Indlela eqhelekileyo yokususa ukungcola kwegraphite kukubeka imveliso eyenziwe ngegraphiti kwirhasi yehalogen kwaye uyifudumeze ukuya kutsho kuma-2000°C.
12. Unyango lomphezulu
Ngokuxhomekeke ekusetyenzisweni kwegraphite, ubuso bayo bunomhlaba kwaye bube nobuso obugudileyo.
13. Ukuthumela ngenqanawa
Emva kokucubungula okokugqibela, iinkcukacha zegraphite ezigqityiweyo zipakishwe kwaye zithunyelwe kumthengi.
Ngolwazi oluthe kratya malunga nobukhulu obukhoyo, amabanga egraphite ye-isostatic kunye namaxabiso, nceda uzive ukhululekile ukuqhagamshelana nathi. Iinjineli zethu ziya kukuvuyela ukukucebisa ngezinto ezifanelekileyo kwaye uphendule yonke imibuzo yakho.
