Iresiphi ye-greyitititite ye-carbide ye-carbider: isitshixo sokusebenza kakhulu

Kwilizwe le-mentergy kunye nesayensi yezixhobo,inqabilesisixhobo esibalulekileyo sokunyibilika kwaye siphose izinyithi. Phakathi kweentlobo ngeentlobo zeenqaba ezinqabileyo, zegrafiti ye-selichen ye-silicon (i-SIC) ye-carbide (i-SIC) ivela kwipropathi yazo ekhethekileyo, njengokuphumelela okuphezulu, nokungazinzanga okuphezulu kothusayo. Kweli nqaku, siza kuqhuba kwiresiphi yegrafu egrafiki kwaye iphonononge indlela ukwakhiwa kwabo kubangela ukuba kube negalelo kwindlela abasebenza ngayo kwizicelo zeqondo eliphezulu.

Izithako ezisisiseko

Izinto eziphambili zegrafu ye-graphite ye-graphite ye-FADKILS yi-flake igrafu kunye ne-silicon carbide. I-Flake igrafu, idla ngokwenza i-40% -50% ye-on esithe tye, inika ukuqhubela phambili kwengqondo kunye nokungasebenzi, nto leyo enceda ekukhululweni kwesinyithi. I-Silicon Carbide, esenza i-20% -50% ye-on esithe tye, inoxanduva lokungaxhathisi okwenzakalisayo kunye nokuzinza kweekhemikhali kumaqondo obushushu aphakamileyo.

Icandelo elongezelelweyo lokuphucula intsebenzo

Ukuqhubela phambili ukuphucula ukusebenza kobushushu obuphezulu kunye nokuzinza kwamachiza okubakho, kongezwa izinto ezinokongezwayo kwiresiphi:

1. I-Slemental Silicon Powder (4% -10%): Yandisa amandla obushushu obukhuselekileyo kunye nokuchasana kwe-oxidation kwezi zinqabile.
2. I-Boron carbide Powder (1% -5%): Ukunyusa uzinzo kunye nokunyangwa kwizinyithi ezibonakalayo.
3. Udongwe (5% -15%): Izenzo njenge-Binder kwaye iphucule amandla omatshini kunye nokuzinza kwe-thermal ezibethelelekileyo.
4. I-thermoser binder (5% -10%): inceda ekubopheleni onke amacandelo kunye ukwenza isakhiwo esibonakalayo.

Ifomula ePhakamileyo

Izicelo ezifunwayo ngokusebenza okuphezulu, ifomula enqabileyo yegrafu iqashiwe. Le fomula iquka amasuntswana angama-98%, i-2% ye-calcoum oxide, i-1% ye-zurium oxide, i-1% ye-BORIC Acid, i-1% sodium saldium, kunye ne-1% ye-Aluminium. Ezi zithako ezongezelelweyo zibonelela ngokuchaseneyo nokunganyangeki kweqondo lobushushu kunye nezomgangatho yobundlobongela.

Inkqubo yokwenziwa kwemveliso

Ukulungiswa kwe-graphite ye-GIC Crubibles kubandakanya inkqubo yengqondo. Ekuqaleni, i-flake igrafu kunye ne-silicon carbide ixube ngokucokisekileyo. Emva koko, i-Scien Silicon Powder, i-boron carbide powder, udongwe, kunye ne-thermoset binder yongezwa kumxube. Ukudityaniswa emva koko kucinezelwa ukuba kusetyenziswe umatshini woshicilelo obandayo. Okokugqibela, iinqaba ezinqatyisiweyo zenziwe kwiqondo lobushushu eliphezulu lokuphucula amandla abo obuchwephesha kunye nozinzo lobushushu.

Izicelo kunye nezibonelelo

Igrafu ye-graphy isetyenziswe ngokubanzi kumzi-mveliso wensimbi yokunyibilika kwaye iphosa izinyithi ezinjengesinyithi, intsimbi, kunye ne-aluminium. Ukuqhubela phambili kwabo okuphakamileyo kuqinisekisa ukufudumeza okulinganayo kwaye kunciphisa ukusetyenziswa kwamandla. Ukungaxhathisi okuphezulu kwe-thermal onqengqelekayo kunciphisa umngcipheko wokuqhekeka ngexesha lokutshintsha kobushushu obukhawulezileyo, ngelixa uzinzo lwazo lweekhemikhali luqinisekisa ubunyulu bentsimbi etyhidiweyo.

Ukuqukumbela, iresiphi yegrafu yegraficial carbles ngumdibaniso ofanelekileyo wezinto ezibonelela ngemali esemthethweni yokuqhutywa kweMpumelelo, ukuchasana kwe-thermal ukothuka. Oku kwenziwa kwenza ukuba babe nakho ukupheliswa kwicandelo le-menteurgy, apho badlala indima ebaluleke kakhulu ekuphumeni okukuko nangokuthembekileyo nokuphoswa kwezinyithi.

Ngokuqonda amacandelo kunye nenkqubo yokwenza imveliso ye-grafu ye-grafu, amashishini anokwenza ukhetho olunolwazi lwezicelo zawo, aqinisekisa ukusebenza kakuhle kunye nobomi babo obude bebethelele. Njengoko inkqubela phambili yetekhnoloji, ezinye izixhasi eziphezulu kwiindlela zokupheka nemveliso ye-SIC ye-graphy zilindelwe, zihamba ngendlela efanelekileyo iinkqubo ezifanelekileyo nezizinzileyo.
