Ufa wa graphite umakonzedwa kuchokera ku graphite yotambasuka kapena graphite yosinthasintha. Mitundu ya pepala la graphite ikhoza kugawidwa m'magulu awiri: pepala losinthasintha la graphite, pepala lotsekera la graphite, pepala la graphite lopyapyala kwambiri, pepala la graphite lotenthetsera kutentha, ndi zina zotero. M'munda wotsekera mafakitale, pepala lotsekera la graphite ndilo lomwe limagwiritsidwa ntchito kwambiri. Mitundu ya pepala losinthasintha la graphite, pepala lotsekera la graphite, pepala la graphite lopyapyala kwambiri, ndi zina zotero ndi yokwanira ndipo imagwiritsidwa ntchito m'mafakitale osiyanasiyana.
Pepala la graphite limapangidwa kuchokera ku graphite yotambasuka kudzera mu kukanikiza, kuzunguliza ndi calcination. Lili ndi kukana kutentha kwambiri, kutentha kosinthasintha, kusinthasintha, kulimba mtima komanso magwiridwe antchito abwino kwambiri otsekera. Pepala la graphite labwino kwambiri lili ndi magwiridwe antchito abwino kwambiri otsekera, ndi lopyapyala komanso lopepuka, ndipo ndi losavuta kudula. Chifukwa cha mawonekedwe ake otsekera ndi kutentha, pepala la graphite limagwiritsidwa ntchito makamaka m'mafakitale otsekera ndi kutentha. Pepala la graphite lomwe limagwiritsidwa ntchito potsekera ndi lopyapyala ndipo lili ndi ubwino wosavuta kudula ndi kukonza, losatentha, losatha kutha, losagwira dzimbiri, lokhala ndi magwiridwe antchito abwino otsekera komanso nthawi yayitali yosinthira. Ubwino wa pepala la graphite potsekera wakhala ndi gawo lofunika kwambiri m'mafakitale otsekera. Ubwino uwu wa pepala la graphite potsekera ukhoza kukwaniritsa zofunikira zotsekera m'mafakitale. Pepala la graphite potsekera likhoza kukonzedwa kukhala mphete zotsekera za graphite, mphete zotsekera za graphite, magasket otsekera a graphite, kulongedza graphite ndi zinthu zina zotsekera za graphite. Lingagwiritsidwe ntchito potsekera pamalo olumikizira mapaipi, ma valve, mapampu, ndi zina zotero, komanso potsekera makina mosinthasintha komanso mosasunthika. Kugwiritsa ntchito pepala la graphite potseka ngati zinthu zopangira zida zotsekera za graphite. Limagwiritsa ntchito bwino ubwino wa pepala la graphite potseka ndipo ndi chinthu chofunikira kwambiri popanga zotsekera zamafakitale. Pepala la graphite limagwira ntchito yofunika kwambiri m'magawo otsekera ndi kutayira kutentha.
Ndi kufulumizitsa kusintha ndi kusintha zinthu zamagetsi komanso kufunikira kwakukulu kwa kasamalidwe ka kutenthetsa kutentha kwa zipangizo zamagetsi zazing'ono, zolumikizidwa bwino komanso zogwira ntchito bwino, ukadaulo watsopano wotenthetsa kutentha kwa zinthu zamagetsi wayambitsidwanso, womwe ndi njira yatsopano yotenthetsera kutentha kwa zinthu za graphite. Njira yatsopano yachilengedwe ya graphite iyi imagwiritsa ntchito bwino kutenthetsa kutentha kwambiri, malo ochepa okhala ndi pepala la graphite lolemera pang'ono. Imachita kutentha mofanana mbali zonse ziwiri, imachotsa madera "otentha", ndikukweza magwiridwe antchito a zamagetsi ogwiritsa ntchito pomwe ikuteteza magwero a kutentha ndi zigawo zake.
Pepala la graphite ndi chinthu chopangidwa ndi graphite chomwe chimapangidwa pogwiritsa ntchito mankhwala pochiza graphite ya phosphorous flake yokhala ndi mpweya wambiri kenako n’kuikulitsa ndi kuizunguliza kutentha kwambiri. Limagwiritsidwa ntchito ngati chinthu chofunikira kwambiri popanga zisindikizo zosiyanasiyana za graphite.
Ntchito zake zazikulu: Pepala la graphite, lomwe limadziwikanso kuti pepala la graphite, limagwiritsa ntchito mwayi wake wokana kutentha kwambiri komanso kukana dzimbiri.
Ufa wa grafiti
Kugwira ntchito bwino kwa magetsi kumathandiza kuti igwiritsidwe ntchito mu mafuta, uinjiniya wa mankhwala ndi zamagetsi. Zipangizo kapena zigawo zake zoopsa, zoyaka moto komanso zotentha kwambiri zimatha kupangidwa kukhala mipiringidzo yosiyanasiyana ya graphite, zodzaza, ma gasket otsekera, mbale zophatikizika, ma gasket a silinda, ndi zina zotero.
Ndi kufulumizitsa kusintha ndi kusintha zinthu zamagetsi komanso kufunikira kwakukulu kwa kasamalidwe ka kutenthetsa kutentha kwa zipangizo zamagetsi zazing'ono, zolumikizidwa bwino komanso zogwira ntchito bwino, ukadaulo watsopano wotenthetsa kutentha kwa zinthu zamagetsi wayambitsidwanso, womwe ndi njira yatsopano yotenthetsera kutentha kwa zinthu za graphite. Njira yatsopano yachilengedwe ya graphite iyi imagwiritsa ntchito bwino kutenthetsa kutentha kwambiri, malo ochepa okhala ndi pepala la graphite lolemera pang'ono. Imachita kutentha mofanana mbali zonse ziwiri, imachotsa madera "otentha", ndikukweza magwiridwe antchito a zamagetsi ogwiritsa ntchito pomwe ikuteteza magwero a kutentha ndi zigawo zake.
Kugwiritsa ntchito kwakukulu kwa ukadaulo watsopano wa pepala la graphite: Umagwiritsidwa ntchito pa makompyuta a laputopu, zowonetsera za flat panel, makamera a digito, mafoni am'manja ndi zida zothandizira anthu, ndi zina zotero.
1. Kutulutsa kosakhazikika kumayambiriro kwa kukonza
Chifukwa cha zochitika:
Poyamba kugwiritsa ntchito ma electrode amagetsi pogwiritsa ntchito ma graphite, chifukwa cha malo ochepa olumikizirana ndi workpiece kapena kukhalapo kwa ma chips ndi ma burrs odulidwa, kutulutsa kochulukirapo kumachitika. Komanso, chifukwa cha mphamvu yayikulu yotulutsa (mphamvu yayikulu komanso m'lifupi mwa pulse), pomwe nthawi yolumikizira pulse ndi yopapatiza kwambiri ndipo kuthamanga kwa jet ndi kwakukulu kwambiri, kutulutsa kumakhala kosakhazikika kumayambiriro kwa kukonza, ndipo ngakhale zochitika zokoka arc zimachitika.

Komanso, chifukwa cha mphamvu yayikulu yotulutsa (mphamvu yayikulu komanso m'lifupi mwa pulse), pomwe nthawi yolumikizira pulse ndi yopapatiza kwambiri ndipo kuthamanga kwa jet ndi kwakukulu kwambiri, kutulutsa kumakhala kosakhazikika kumayambiriro kwa kukonza, ndipo ngakhale zochitika zokoka arc zimachitika.
Yankho:
1. Musanagwiritse ntchito, ndikofunikira kuchotsa kwathunthu tchipisi ndi ma burrs omwe amamatira ku workpiece, komanso mafilimu a oxide, zokutira, dzimbiri ndi zinthu zina zomwe zimapangidwa ndi kutentha kwa workpiece.
2. Ikani mphamvu yamagetsi pamtengo wotsika kwambiri pachiyambi. Kenako pang'onopang'ono iwonjezereni kufika pa mphamvu yamagetsi yapamwamba kwambiri ndikuchepetsa kuthamanga kwa jet.
2. Ma granular protrusions amapangidwa
Chifukwa cha zochitika:
1. Ngati m'lifupi mwa pulse mwayikidwa kwambiri, ma granular protrusions adzapangidwa pamakona a electrode, zomwe zingayambitse short circuit ndikupangitsa kuti arc discharge ichitike.
2. Pali ma chip ambiri okonza zinthu zamagetsi, omwe sangatulutsidwe munthawi yake. Ngati ngodya ya nozzle yamadzimadzi okonza zinthu yayikidwa molakwika, madzi okonza zinthu sangalowetsedwe mokwanira mumpata, ndipo zinthu zamagetsi ndi ma chip okonza zinthu sizingatulutsidwe mokwanira. Pamene kuya kwa processing kuli kozama kwambiri, ma chip okonza zinthu sangatulutsidwe mokwanira ndipo amakhalabe pansi.
Yankho:
1. Fupikitsani m'lifupi mwa pulse (Ton), onjezerani nthawi ya pulse (Toff), ndikuletsa kupanga ma granular protrusions ndi kupanga zinthu zamagetsi zomwe zimakokoloka ndi ma processing chips.
2. Yesani kuyika nozzle pambali pa elekitirodi. Ngati kuya kwa processing kuli kozama kwambiri,
3. Wonjezerani kuchuluka kwa ma electrode odumphadumpha, fulumizitsani liwiro la kulumpha, ndikufupikitsa nthawi yotulutsa.
3. Kutsika kwa madzi kumachitika pansi pa nthaka panthawi yokonza
Chifukwa cha zochitika:
Pa nthawi yokonza magetsi, ngati nthawi ya kugunda kwa mtima ndi yochepa kwambiri, liwiro lokwera ndi kutsika la electrode ndi lochepa, ndipo kuthamanga kwa jet ndi kofooka, ma chips opangira zinthu zamagetsi zokokoloka sangathe kutulutsidwa mokwanira. Kuphatikiza apo, zinthu zambiri zamagetsi zokokoloka zimamatira pansi pa electrode, ndikupanga ma blocks okhala ndi kaboni, omwe amatha kusweka panthawi yoyendetsa electrode mmwamba ndi pansi, zomwe zimapangitsa kuti pansi pa processing pakhale kutsika.
Yankho:
1. Wonjezerani nthawi ya kugunda kwa mtima.
2. Wonjezerani liwiro la kulumpha kwa ma electrode.
3. Wonjezerani kuthamanga kwa ndege.
4. Gwiritsani ntchito burashi kuti muyeretse tchipisi ta makina kuchokera kumapeto kwa elekitirodi ndi pansi pa ntchito yokonza.
4. Kusakhazikika ndi kupindika kwa pansi
Chifukwa cha zochitika:
Chifukwa cha kuchepa kwa nthawi ya kugunda kwa mtima, kuthamanga kwa jet sikufanana, mpata pakati pa ma electrode ndi wochepa kwambiri, ndipo zinthu zomwe zimakokoloka ndi magetsi sizingatulutsidwe mokwanira. Komanso, zimagawidwa mosagwirizana pamwamba pa processing. Pamene processing ikupitirira, kupindika kumachitika pansi kapena kukhwima kwa pansi pa processing sikufanana.
Yankho:
1. Onjezani nthawi ya kugunda kwa mtima ndikukhazikitsa kuthamanga kwa jet kosalekeza.
2. Wonjezerani kusiyana kwa ma electrode ndipo nthawi zambiri onani momwe chip imachotsedwera.
