I-Isostatic icinezelwe igraphite luhlobo olutsha lwemathiriyeli yegraphite, ene-conductivity egqwesileyo yombane, ukumelana nobushushu obuphezulu kunye nokuzinza kweekhemikhali, ngoko ke isetyenziswa kakhulu kwiinkalo ezininzi zobugcisa obuphezulu.Eli phepha liza kwazisa ngokweenkcukacha inkqubo yemveliso, usetyenziso oluphambili kunye nentsingiselo yophuhliso yexesha elizayo yegraphite ecinezelekileyo ye-isostatic.
Inkqubo yokuveliswa kwegraphite ecinezelekileyo ye-isostatic
Inkqubo yemveliso yegraphite isostatic ikakhulu ibandakanya la manyathelo alandelayo:
1. Ukulungiswa kwezinto ezikrwada: Izinto ezisetyenziswayo zegraphite ecinezelweyo ye-isostatic ziquka i-aggregate kunye ne-binder.I-aggregate idla ngokwenziwa nge-petroleum coke okanye i-asphalt coke, efuna ukubalwa kwi-1200 ~ 1400℃ ukususa ukufuma kunye nokuguquguquka ngaphambi kokuba isetyenziswe.I-binder yenziwe nge-coal pitch okanye i-petroleum pitch, eyandisa kwaye ivumelane nge-synchronously kunye ne-aggregate ukuqinisekisa i-isotropy yezinto eziphathekayo.
2. Ukusila: Izinto ezikrwada zigutyungelwa zibe ngumgubo ocolekileyo, odla ngokufuna ukuba ubukhulu be-aggregate bufikelele kwi-20um okanye ngaphantsi.Igraphite ecokisekileyo ye-isostatically ecinezelekileyo, ene-particle diameter ye-1μm, ilungile kakhulu.
3. Uxinzelelo lwe-isostatic ebandayo: Beka umgubo womhlaba kumatshini obandayo we-isostatic kwaye ucinezele ukuba wenze phantsi koxinzelelo oluphezulu.
4. Ukugcoba: I-graphite ebunjiweyo ifakwe kwi-oven yokubhaka kwaye yosiwe kwiqondo lokushisa eliphezulu ukuphucula ngakumbi iqondo le-graphitization.
5. Umjikelo wokukroziswa kwe-Impregnation-roasting: Ukuze kuphunyezwe ingxinano ekujoliswe kuyo, kufuneka imijikelo yokuqhotsa izihlandlo ezininzi.Umjikelo ngamnye unyusa ukuxinana kwegraphite, ukuphumeza amandla aphezulu kunye nokuhamba kombane.
Ukusetyenziswa okuphambili kwegraphite ye-isostatic kubandakanya oku kulandelayo:
1. Intsimi ye-elektroniki: I-graphite ecinezelekileyo ye-Isostatically isetyenziswa ngokubanzi kwintsimi ye-electronics ngenxa ye-conductivity yayo yombane.Ngokukodwa kwimimandla yeebhetri, i-electrode, izixhobo zesemiconductor, njl. njl., ukuhanjiswa kombane okugqwesileyo kwenza igraphite ecinezelekileyo ye-isostatic ibe yinto eyimfuneko.
2. Intsimi ye-Aerospace: i-graphite ecinezelekileyo ye-isostatic ineempawu zokumelana nokushisa okuphezulu, ukuzinza kweekhemikhali kunye namandla aphezulu, ngoko isetyenziswa ngokubanzi kwintsimi ye-aerospace.Ngokomzekelo, kwii-injini ze-rocket kunye ne-space probes, i-graphite ecinezelekileyo ye-isostatically isetyenziselwa ukwenza amacandelo okuqhuba umbane phantsi kobushushu obuphezulu, iimeko zoxinzelelo oluphezulu.
3. I-Automotive field: isostatic pressed graphite iphinda isetyenziswe ngokubanzi kwintsimi yeemoto.Ngokomzekelo, kwintsimi yeebhetri, i-graphite ecinezelwe nge-isostatically isetyenziselwa ukwenza i-electrode yebhetri esebenza kakhulu.Ukongeza, kumacandelo enjini yeemoto, igraphite ecinezelweyo ye-isostatic ikwasetyenziselwa ukwenza izitywina kunye nokunxiba iinxalenye phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.
4. Eminye imimandla: Ukongeza kule mimandla ingentla, i-graphite ye-isostatic iphinda isetyenziswe ngokubanzi kumandla, imboni yeekhemikhali, i-metallurgy kunye nezinye iindawo.Ngokomzekelo, kwintsimi yeeseli zelanga, i-graphite ecinezelwe nge-isostatically isetyenziselwa ukwenza i-electrode esebenzayo kunye ne-conductive substrates.Kwishishini lemichiza, i-graphite ecinezelwe nge-isostatically isetyenziselwa ukwenza imibhobho kunye nezikhongozeli ezinokumelana nokugqwala okuphezulu.Kwi-metallurgy, igraphite ecinezelekileyo isetyenziselwa ukwenza izitovu zobushushu obuphezulu kunye nee-electrode.
Njengohlobo olutsha lwezinto zegraphite, i-isostatic pressed graphite inoluhlu olubanzi lokusetyenziswa kunye nexabiso elibalulekileyo.Inkqubo yayo yemveliso intsonkothile kwaye intekenteke, kwaye kufuneka idlule kumanyathelo amaninzi ukuyigqiba.Nangona kunjalo, ngala manyathelo enkqubo entsonkothileyo enza ukuba igraphite ecinezelekileyo ibe neempawu ezibalaseleyo kunye nethemba losetyenziso olubanzi.Kwixesha elizayo, kunye nenkqubela phambili eqhubekayo yesayensi kunye nobuchwepheshe kunye nokwandiswa kweendawo zokusetyenziswa, i-graphite ecinezelweyo ye-isostatic iya kusetyenziswa ngokubanzi kwaye ikhuthazwe.Kwangaxeshanye, uphando kunye nokuphuculwa kwenkqubo yemveliso kunye nethekhnoloji iya kuba yinto ekugxilwe kuyo uphando.Kukholelwa ukuba kwikamva elingekude, isostatic graphite iya kusizisa izinto ezimangalisayo kunye nezinto ezinokwenzeka.
