I-graphite powder icutshungulwa kusuka ku-graphite enwetshiwe noma i-flexible graphite. Izinhlobo zephepha le-graphite zingahlukaniswa zibe iphepha le-graphite eliguquguqukayo, iphepha le-graphite elivala uphawu, iphepha le-graphite elincane kakhulu, iphepha le-graphite elishisayo elishisayo, njll. Emkhakheni wokuvala izimboni, ukuvala iphepha le-graphite yilona elisetshenziswa kakhulu. Izinhlobo zephepha le-graphite eliguquguqukayo, iphepha le-graphite elivala uphawu, iphepha le-graphite elincanyana kakhulu, njll. zonke ziphelele kakhulu futhi zinezinhlobonhlobo zezicelo zezimboni.
Iphepha le-graphite lenziwa nge-graphite eyandisiwe ngokucindezela, ukugoqa kanye nokubala. Ifaka ukumelana nezinga lokushisa eliphezulu, i-thermal conductivity, ukuguquguquka, ukuqina nokusebenza okuhle kakhulu kokuvala. Iphepha le-graphite lekhwalithi ephezulu linokusebenza okuhle kakhulu kokuvala, lincane futhi lilula ngesisindo, futhi kulula ukulisika. Ngenxa yezakhiwo zalo zokuvala nokushisa, iphepha le-graphite lisetshenziswa kakhulu ezindaweni zokuvala izimboni kanye nokukhipha ukushisa. Iphepha le-graphite elisetshenziselwa ukuvala lincane futhi linezinzuzo zokuba lula ukusika nokucutshungulwa, ukumelana nokushisa, ukumelana nokuguga, ukumelana nokugqwala, ukusebenza kahle kokuvala kanye nomjikelezo omude wokushintsha. Izinzuzo zephepha le-graphite lokuvala uphawu ziye zadlala indima ebaluleke kakhulu emkhakheni wokuvalwa kwezimboni. Lezi zinzuzo zephepha le-graphite lokubekwa uphawu zingahlangabezana nezidingo zokuvalwa kwezimboni. Iphepha le-graphite lokuvalwa lingacutshungulwa libe izindandatho zokuvala ze-graphite, izindandatho zokuvala ze-graphite, ama-gaskets okuvalwa kwe-graphite, ukupakishwa kwe-graphite neminye imikhiqizo yokuvala i-graphite. Ingasetshenziselwa ukuvala izindawo zokuhlangana zamapayipi, ama-valve, amaphampu, njll., kanye nokuvala uphawu kwemishini okuguquguqukayo nokumile. Ukusebenzisa iphepha le-graphite ukuze libekwe uphawu njengezinto ezingavuthiwe zezingxenye zokuvala i-graphite Isebenzisa ngokugcwele izinzuzo zephepha le-graphite ukuze lifakwe uphawu futhi liyinto ebaluleke kakhulu ekukhiqizweni kokuvalwa kwezimboni. Iphepha le-graphite lidlala indima ebaluleke kakhulu emikhakheni yokuvala nokukhipha ukushisa.
Ngokusheshisa ukuthuthukiswa nokushintshwa kwemikhiqizo kagesi kanye nesidingo esandayo sokulawulwa kokuchithwa kokushisa kwemishini emincane, edidiyelwe kakhulu futhi esebenza kahle kakhulu, sekwethulwe nobuchwepheshe obusha sha bokukhipha ukushisa kwemikhiqizo ye-elekthronikhi, okuyisixazululo esisha sokukhipha ukushisa kwe-graphite. Lesi sixazululo esisha sha semvelo se-graphite sisebenzisa ukusebenza kahle kokushisa okuphezulu, ukusebenza kwesikhala esincane nesisindo esincane sephepha legraphite. Iphatha ukushisa ngendlela efanayo kuzo zombili izinkomba, iqeda izindawo “ezishisayo”, futhi ithuthukisa ukusebenza kwama-electronics abathengi kuyilapho ivikela imithombo yokushisa nezingxenye.
Iphepha le-graphite liwumkhiqizo we-graphite owenziwe ngokwelapha ngamakhemikhali i-high-carbon phosphorus flake graphite bese ulibeka ngaphansi kokunwetshwa nokugingqika okunezinga lokushisa eliphezulu. Isebenza njengezinto eziyisisekelo zokukhiqiza ama-graphite seal ahlukahlukene.
Ukusetshenziswa kwalo okuyinhloko: Iphepha le-graphite, elaziwa nangokuthi ishidi le-graphite, lisizakala ngokumelana kwalo nezinga lokushisa eliphezulu kanye nokumelana nokugqwala.
I-graphite powder
Isici se-conductivity kagesi enhle siyenza isetshenziswe ku-petroleum, ubunjiniyela bamakhemikhali kanye ne-electronics. Izinto ezinobuthi, ezivuthayo nezinokushisa okuphezulu noma izakhi zingenziwa zibe yimichilo ehlukahlukene ye-graphite, ama-filler, ama-gaskets okuvalwa, amapuleti ahlanganisiwe, ama-cylinder gaskets, njll.
Ngokusheshisa ukuthuthukiswa nokushintshwa kwemikhiqizo kagesi kanye nesidingo esandayo sokulawulwa kokuchithwa kokushisa kwemishini emincane, edidiyelwe kakhulu futhi esebenza kahle kakhulu, sekwethulwe nobuchwepheshe obusha sha bokukhipha ukushisa kwemikhiqizo ye-elekthronikhi, okuyisixazululo esisha sokukhipha ukushisa kwe-graphite. Lesi sixazululo esisha sha semvelo se-graphite sisebenzisa ukusebenza kahle kokushisa okuphezulu, ukusebenza kwesikhala esincane nesisindo esincane sephepha legraphite. Iphatha ukushisa ngendlela efanayo kuzo zombili izinkomba, iqeda izindawo “ezishisayo”, futhi ithuthukisa ukusebenza kwama-electronics abathengi kuyilapho ivikela imithombo yokushisa nezingxenye.
Ukusetshenziswa okuyinhloko kwalobu buchwepheshe bokufaka isicelo sephepha elisha le-graphite: Kusetshenziswa kumakhompiyutha ezincwadi, izibonisi zephaneli eyisicaba, amakhamera evidiyo edijithali, omakhalekhukhwini kanye namadivayisi omsizi womuntu siqu, njll.
1. Ukukhishwa okungazinzile ekuqaleni kokucubungula
Imbangela yesigameko:
Esigabeni sokuqala somshini kagesi ngama-electrode e-graphite, ngenxa yendawo encane yokuxhumana ye-workpiece noma ukuba khona kwama-chips okusika kanye nama-burrs, ukukhishwa okugxilile kwenzeka. Ngaphezu kwalokho, ngenxa yamandla amakhulu okukhipha (isilinganiso esiphezulu samanje nobubanzi be-pulse ububanzi), kuyilapho isikhawu se-pulse sincane kakhulu futhi ingcindezi ye-jet iphezulu kakhulu, ukukhishwa akuzinzile ekuqaleni kokucubungula, ngisho nezimo zokudonsa i-arc zenzeka.

Ngaphezu kwalokho, ngenxa yamandla amakhulu okukhipha (isilinganiso esiphezulu samanje nobubanzi be-pulse ububanzi), kuyilapho isikhawu se-pulse sincane kakhulu futhi ingcindezi ye-jet iphezulu kakhulu, ukukhishwa akuzinzile ekuqaleni kokucubungula, ngisho nezimo zokudonsa i-arc zenzeka.
Isixazululo:
I-1.Ngaphambi kokucubungula, kuyadingeka ukususa ngokuphelele ama-chips nama-burrs anamathele ku-workpiece, kanye namafilimu e-oxide, ama-coatings, ukugqwala nezinye izinto ezikhiqizwa ukwelashwa okushisa kwe-workpiece.
2. Setha okwamanje ngenani eliphansi uma kuqhathaniswa ekuqaleni. Bese ukhulisa kancane kancane kuze kube manje futhi usethe ingcindezi ye-jet ibe mncane.
2. Ama-protrusions angama-Granular akhiqizwa
Imbangela yesigameko:
1.Uma ububanzi be-pulse busethwe bukhulu kakhulu, ama-protrusions granular azokwakhiwa emagumbini e-electrode, okungabangela umjikelezo omfushane futhi kuholele ekukhishweni kwe-arc.
2. Kunama-chips amaningi okucubungula emikhiqizo ye-electro-rosion, engakwazi ukukhishwa ngesikhathi. Uma i-engeli yenozi yoketshezi olucutshungulwayo isethwe ngokungalungile, uketshezi olucutshungulwayo alukwazi ukujovwa ngokugcwele esikhaleni, futhi imikhiqizo yokuguguleka kwe-electro-rosion nama-chips okucubungula akukwazi ukukhishwa ngokugcwele. Uma ukujula kokucubungula kujule kakhulu, ama-chips okucubungula awakwazi ukukhishwa ngokugcwele futhi ahlale phansi.
Isixazululo:
1.Nciphisa ububanzi be-pulse (Ton), nweba isikhawu se-pulse (Toff), futhi ucindezele ukukhiqizwa kwama-granular protrusions kanye nokwakhiwa kwemikhiqizo yokuguguleka kagesi kanye nama-chips okucubungula.
2. Zama ukubeka i-nozzle eceleni kwe-electrode. Uma ukujula kokucubungula kujule kakhulu,
3. Khulisa inani le-electrode jump, usheshise ijubane lokugxuma, futhi unciphise isikhathi sokukhipha.
3. Ukucindezeleka kwenzeka endaweni ephansi ngesikhathi sokucubungula
Imbangela yesigameko:
Ngesikhathi senqubo yomshini wokukhipha ugesi, uma isikhawu sokushaya kwenhliziyo sisincane kakhulu, ijubane lokugxuma elikhuphuka naphansi le-electrode lihamba kancane, futhi nomfutho wejethi ubuthakathaka, ama-chips okucubungula emikhiqizo yokuguguleka kagesi awakwazi ukudedelwa ngokugcwele. Ngaphezu kwalokho, imikhiqizo eminingi yokuguguleka kagesi inamathela endaweni engaphansi ye-electrode, yenze amabhlogo ane-carbonized, athambekele ekuqhekekeni ngesikhathi sokunyakaza kwe-electrode phezulu naphansi, okuholela ekucindezelekeni endaweni ephansi yokucubungula.
Isixazululo:
1. Nweba isikhawu sokushaya kwenhliziyo.
2. Khulisa isivinini sokugxuma i-electrode.
3. Khulisa umfutho wejethi.
4. Sebenzisa ibhulashi ukuze uhlanze ama-chips omshini kusukela ekugcineni kwe-electrode kanye nendawo engaphansi yokucubungula.
4. Ukungalingani nokugoba kwendawo engaphansi
Imbangela yesigameko:
Ngenxa yesikhawu esincane kakhulu se-pulse, ingcindezi ye-jet ayilingani, igebe phakathi kwama-electrode lincane kakhulu, futhi imikhiqizo ye-electro-rosion ayikwazi ukukhishwa ngokugcwele. Ngaphezu kwalokho, asatshalaliswa ngokungalingani endaweni engaphansi yokucubungula. Njengoba ukucutshungulwa kuqhubeka, ukugoba kwenzeka endaweni engaphansi noma ubulukhuni bendawo engaphansi yokucubungula ayilingani.
Isixazululo:
1.Khulisa i-pulse interval bese usetha i-jet pressure njalo.
2. Khulisa igebe le-inter-electrode futhi uhlole njalo isimo sokususwa kwe-chip.
