Pali mitundu yambiri ya zinthu zoyera kwambiri za graphite, zomwe zimatha kupangidwa kukhala mbale, midadada, mapaipi, mipiringidzo, ufa ndi mitundu ina molingana ndi ntchito zosiyanasiyana.
1. Plate: Mpukutu wapamwamba kwambiri wa graphite umapangidwa ndi kutentha ndi kupanikizika. Makhalidwe ake akuluakulu ndi kachulukidwe kwambiri ndi mphamvu, kufanana kwabwino, kukula kokhazikika, kutsirizika kwapamwamba, ndi mphamvu zamagetsi zokhazikika komanso zopingasa. Nthawi zambiri amagwiritsidwa ntchito m'magawo ogawa matenthedwe, mbale zoteteza mlengalenga, zakuthambo ndi zina zotero mu ng'anjo ya vacuum yotentha kwambiri.
2. Block: high-purity graphite block ndi mankhwala omwe ali ndi mawonekedwe osasinthasintha. Kupanga kwake kumakhala kosavuta ndipo mtengo wake ndi wotsika. Choncho, midadada mkulu-chiyero graphite chimagwiritsidwa ntchito Machining, zipangizo elekitirodi, mavavu, zipangizo conductive, etc.
3. Mipope: mipope yoyera ya graphite nthawi zambiri imagwiritsidwa ntchito muumisiri wamankhwala pansi pa malo owononga monga asidi amphamvu, alkali wamphamvu, kutentha kwambiri komanso kuthamanga kwambiri, monga ketulo ya nsanja, chotenthetsera kutentha, condenser, payipi ya nthunzi, etc.
4. Bar: High-purity graphite bar ndi chinthu chothandiza kwambiri, chokhala ndi ntchito zambiri. Nthawi zambiri amagwiritsidwa ntchito popanga maelekitirodi, zida zopangira, zolumikizira zamkuwa, ma gratings a photocathode, machubu akupumulira ndi mbale zotenthetsera zamagetsi zamagetsi.
5. Ufa: ufa ndi chinthu choyera kwambiri cha graphite chosungirako bwino komanso choyendetsa, choncho chimagwiritsidwa ntchito kwambiri muzinthu zodzaza polima, zipangizo za electrode, zipangizo zamagetsi zamagetsi, zokutira zotsutsana ndi kutu, etc.
High-purity graphite ili ndi izi:
1. Kukana kwa dzimbiri: chiyero chapamwamba cha graphite chimatha kukana kukokoloka kwa mitundu yosiyanasiyana yamankhwala, monga oxidant, zosungunulira, asidi amphamvu, alkali wamphamvu, ndi zina zambiri.
2. Kukhazikika kwamafuta ambiri: graphite yoyera kwambiri imakhala yokhazikika kwambiri ndipo imatha kupirira kutentha kwambiri. Zogulitsa zina zimatha kugwira ntchito mokhazikika kwa nthawi yayitali kutentha kwambiri kuposa madigiri a 3000.
3. High conductivity ndi mkulu matenthedwe madutsidwe: mkulu-chiyero graphite ali madutsidwe kwambiri ndi matenthedwe madutsidwe, ndipo madutsidwe ake ndi bwino kuposa zitsulo zamkuwa, choncho chimagwiritsidwa ntchito m'minda ya maelekitirodi, zipinda zingalowe ndi zipangizo Kutentha.
4. Zida zamakina apamwamba: graphite yapamwamba kwambiri imakhala ndi makina abwino, ndipo mphamvu zake ndi kuuma kwake ndizokwera kwambiri kuposa zida zachitsulo.
5. Good processability: high chiyero graphite ali kwambiri processing ntchito, amene angagwiritsidwe ntchito pobowola, mphero, kudula waya, dzenje akalowa ndi processing zina, ndipo angapangidwe mu mawonekedwe ovuta.
Kugwiritsidwa ntchito kwakukulu kwa graphite yoyera kwambiri kungagawidwe m'magulu awa:
1. Vacuum mkulu kutentha chipinda: mkulu chiyero graphite mbale ndi zinthu zofunika mu vakuyumu mkulu kutentha ng'anjo ndi mpweya chitetezo ng'anjo, akhoza kupirira kutentha kwambiri ndi zingalowe digiri, ndipo akhoza kuonetsetsa chitetezo ndi bata la nkhani mu ng'anjo kutentha kwambiri.
2. Zinthu za anode: Chifukwa chapamwamba kwambiri komanso kukhazikika kwake, graphite yoyera kwambiri imagwiritsidwa ntchito kwambiri m'mabatire a lithiamu ion, ma electrode a lithiamu batri, machubu a vacuum valve ndi madera ena.
3. Zigawo za graphite: zigawo za graphite zoyera kwambiri zimatha kupangidwa kukhala magawo osiyanasiyana, monga ma washer osindikiza annular, ma graphite molds, etc.
4. Mabwalo a ndege ndi zamlengalenga: graphite yoyera kwambiri imakhala ndi gawo lofunikira kwambiri pamayendedwe apamlengalenga ndi ndege, kupanga zida zamainjini aaero ndi kukana kuvala, kutentha kwambiri, kuthamanga kwambiri komanso kuthamanga kwambiri, ma conductivity amafuta ndi gasket conductive, matenthedwe matenthedwe. zokutira, kompositi zipangizo, etc.
5. Chowotcha cha graphite: Chowotcha cha graphite chimagwiritsidwa ntchito kwambiri mu ng'anjo yotentha ya mafakitale, ng'anjo ya vacuum sintering, ng'anjo yamagetsi ya crucible ndi madera ena chifukwa cha kutentha kwake kwakukulu, kukhazikika kwa kutentha kwakukulu ndi kupulumutsa mphamvu.
6. Phulusa lonse purosesa: Mkulu-kuyera graphite phulusa lonse purosesa ndi mtundu watsopano wa zida zoteteza chilengedwe, amene angagwiritsidwe ntchito zochizira zitsulo zolemera, zinthu organic, styrene ndi zinthu zina mu mafakitale gasi zinyalala gasi ndi zimbudzi mafakitale.
