Dab tsi yog vim li cas rau kev siv graphite hluav taws xob hloov cov hluav taws xob tooj liab?
Cov laj thawj rau kev siv Graphite hluav taws xob hloov chaw tooj liab hluav taws graphite cov khoom yog ua los ntawm cov tshuaj carbon. Graphite yog cov khoom siv uas tau pom kev loj hlob sai hauv kev lag luam ib txwm muaj. Nws siv tsis yog nce (hauv metallurgy, thiab tshuab, kev sib txuas lus, kev tiv thaiv hluav taws xob, kev tiv thaiv biology, thiab ib puag ncig ntawm kev tiv thaiv biology [1 shenzhen]. Graphite blocks yog ib hom duab cuav, uas yog tsim los ntawm cov khoom siv cua sov cream. Feem ntau, yog tias lawv ua kom huv siab kom muaj kev huv siab lossis ua rau cov pa roj carbon fiber, lawv tus nqi ntxiv yuav siab dua.
Graphite hluav taws xob yog tsim los ntawm roj coke thiab koob coke raws li cov ntaub ntawv raw, nrog daim av nplaum ua ke. Lawv tau tsim los ntawm kev saib xyuas, batching, kneading, kneading, nias, ci, ci, graphitization, thiab machining. Lawv yog tus saib xyuas uas kub thiab melt tus nqi nyob rau hauv ib lub rauv hluav taws xob rauv uas muaj hluav taws xob tso rau hauv daim ntawv ntawm arc. Raws li lawv cov ntsuas kev ua tau zoo, lawv tuaj yeem muab faib ua cov khoom siv hluav taws xob, muaj zog, thiab ultra} lub zog loj. Graphite hluav taws xob feem poob ua rau plaub pawg: oxidation graphite electrodes, thiab ultra {6} siab} Cov zog loj graphite hluav taws xob.
Graphite cov pas nrig nquag siv los ua cua sov uas muaj cov cua sov hauv high - sov rawg sov sov, nrog qhov kev ua haujlwm kub siab tshaj plaws txog 3000 degree. Lawv yog cov ntxim haum rau oxidation thaum kub thiab tsuas siv tau hauv nruab nrab lossis txo cov cua hauv nruab nrab, tshwj tsis yog nyob hauv lub tshuab nqus tsev. Lawv muaj cov coefficient ntawm thermal expansion, siab thermal conductivity, thiab kev tiv thaiv (8} ω 13 ω⁻⁶. Lawv muab cov txheej txheem zoo dua li SIC thiab cov pas nrig Mosi₂, tiv taus cov kub siab thiab muaj qhov txias thiab cua sov, thiab yog pheej yig. Cov khoom siv graphite siv nyob rau hauv cov ntawv txheej txheem no yog txias heev yog cov khoom siv elemite, tshwj tsis yog muaj lwm yam kev kawm no tau hais txog qhov kev kawm no tau raug xa mus rau graphite). Cov khoom siv no tau siv thoob ntiaj teb. Hauv Tebchaws Asmeskas, 95% lossis ntau dua ntawm cov neeg siv Xaiv Edm graphite yog lawv cov khoom siv hluav taws xob. Nyob rau hauv lwm lub teb chaws muaj chaw muaj chaw muaj chaw muaj chaw, xws li Nyij Pooj thiab Switzerland, EDM graphite kuj tseem ua haujlwm.
Nyob rau hauv xyoo tsis ntev los no, graphite tau pom ntau dua raws li cov khoom siv hluav taws xob, suav nrog cov khoom lag luam hauv EDM (hauv cov khoom siv hluav taws xob, tshuab hluav taws xob, sib txuas lus, thiab khoom siv hluav taws xob. Graphite muaj qhov ntom ntom ntawm kwv yees li ntawm 1.55 rau 1.85 g / cmÃ, tsuas yog ib {}} tsib ntawm tooj liab. Tsis tas li ntawd, vim nws cov khoom nplaum nplaum, graphite tuaj yeem siv los tsim cov loj, cov khoom siv ua ke ntawm ntau yam duab. Piv rau cov ntaub ntawv loj tooj liab, muaj cov txiaj ntsig zoo xws li muaj zog dua, txo cov hluav taws xob ntxiv, thiab txo cov thermal deformation. Qhov no ua rau nws tsim nyog tshwj xeeb rau cov hluav taws xob siv hauv cov qauv sib xyaw nrog cov qauv sib txawv xws li cov microsters tshwj xeeb xws li siv los ntawm Suav cov tuam ntxhab. Graphite electrodes tau maj mam hloov tooj liab hluav taws xob yog cov ntsiab lus edm electrode cov khoom. Kev ua cov txheej txheem, suav nrog kev xa, milling, sib tsoo, thiab saus, tsuas yog tsim cov electrodes nrog cov duab yooj yim thiab tsawg dua.
Nrog rau kev loj hlob sai thiab kev thov ntawm graphite siab {}} Cov cuab yeej nrawm nrawm, thiab cov cuab yeej siv ib txwm muaj hloov los ntawm high {1} nrawm tshuab hluav taws xob. Lub spindle ceev ntawm graphite siab he {}} ceev ceev machining tshuab ceev feem ntau yog li 60,000 txog 60,000 rpm, nrog pub ceev mus txog 60 m / min. Phab ntsa tuab tuaj yeem tsawg dua 0.000 mm. Cov fillets me me tuaj yeem tsawg dua 0.000 mm, ua kom muaj zog machining zoo thiab meej. Cov kev kho deg tam sim no yog thawj txhais tau tias yog ua tiav tau zoo thiab siab {14} pref precision machining ntawm graphite. Raws li kuv lub teb chaws tsim qauv kev lag luam sai sai txheej txheem loj, cov kev thov kom haum micro {16} {{16} {} Cov pawg ntawm qhov muaj ntau zuj zus. Qhov no tau tsim ib qho kev thov loj rau high- ceev cov ntaub ntawv ua thiab ntau lawm cov khoom siv pwm hauv Suav teb, xav tau ntau dua cov thev naus laus zis thiab tshiab tshaj lij. Thiaj li, graphite elemode tus nqi tau nce ntau zog.
Graphite yog ib qho kev sib cav sib ceg thiab cov khoom siv brittle. Cov graphite chips tsim thaum siab - nrawm milling ib txwm yog cov hmoov av thiab zoo. Txawm tias muaj lub kaw lus muaj zog heev, lawv tau yooj yim tawg, nce, thiab ua raws li sab pem hauv ntej thiab nram qab. Ua ke nrog cov khoom siv graphite sib xyaw ua ke tau ua tiav, lawv tsim cov txiaj ntsig kev sib txawv heev ntawm kev txiav cov cuab yeej. Raws li qhov tshwm sim, lub cuab yeej hnav thiab tawg hauv graphite txiav yog cov teeb meem loj heev.
