Machubu a Graphite
Mawonekedwe
1. Kutentha kwakukulu kwa kutentha: Graphite panopa ndi imodzi mwa zipangizo zotentha kwambiri zomwe zimadziwika.Malo ake osungunuka ndi 3850 ℃± 50 ℃, ndipo kuwira kwake kufika pa 4250 ℃.Imayikidwa pa kutentha kwapamwamba kwambiri pa 7000 ℃ kwa masekondi 10, ndi kutaya kochepa kwambiri kwa graphite, komwe ndi 0.8% kulemera kwake.Kuchokera pa izi, zikhoza kuwoneka kuti kukana kwa kutentha kwa graphite ndikopambana kwambiri.
2. Kukaniza kwapadera kwa kutentha kwa kutentha: Graphite imakhala ndi kutentha kwabwino kwa kutentha, zomwe zikutanthauza kuti pamene kutentha kumasintha mwadzidzidzi, coefficient of thermal expansion ndi yaying'ono, kotero imakhala ndi kukhazikika kwabwino kwa kutentha ndipo sichidzatulutsa ming'alu pakusintha kwadzidzidzi kutentha.
3. Thermal conductivity ndi conductivity: Graphite ali ndi matenthedwe abwino matenthedwe ndi madutsidwe.Poyerekeza ndi zipangizo wamba, matenthedwe madutsidwe ake ndi mkulu ndithu.Ndipamwamba ka 4 kuposa chitsulo chosapanga dzimbiri, 2 nthawi zambiri kuposa chitsulo cha carbon, ndipo nthawi 100 kuposa zipangizo wamba zosapanga zitsulo.
4. Lubricity: Kupaka mafuta kwa graphite ndi kofanana ndi molybdenum disulfide, ndi friction coefficient yosakwana 0.1.Ntchito yake yopaka mafuta imasiyanasiyana ndi kukula kwa sikelo.Kukula kwa sikelo, kumachepetsa kugundana kwapakati, komanso momwe mafuta amagwirira ntchito bwino.
5. Kukhazikika kwa Chemical: Graphite imakhala ndi kukhazikika kwamankhwala bwino kutentha kwa firiji, ndipo imatha kupirira acid, alkali, ndi organic solvent corrosion.
Mkulu kachulukidwe, kukula bwino mbewu, chiyero mkulu, mphamvu mkulu, kondomu wabwino, madutsidwe wabwino matenthedwe, kukana otsika enieni, mkulu makina mphamvu, yosavuta mwatsatanetsatane processing, kukana zabwino matenthedwe mantha, kukana kutentha, ndi kukana makutidwe ndi okosijeni.Ili ndi zisonyezo zabwino zolimbana ndi dzimbiri zakuthupi komanso zamankhwala ndipo ndiyoyenera mapampu a rotary vane vacuum opanda mafuta.
Graphite ndi imodzi mwazinthu zolimbana ndi kutentha kwambiri.Malo ake osungunuka ndi 3850 ° C + 50 ° C, ndipo malo ake otentha ndi 4250 ° C. Mitundu yosiyanasiyana ndi ma diameter a machubu a graphite amagwiritsidwa ntchito potenthetsa ng'anjo za vacuum ndi minda yotentha.
Isostatic kukanikiza graphite
Lili ndi madulidwe abwino ndi matenthedwe matenthedwe, kukana kutentha kwapamwamba, kocheperako pang'ono pakukulitsa matenthedwe, kudzipaka mafuta, kukana kutentha kwambiri, kukana kwa asidi, kukana kwa alkali, kukana dzimbiri, kachulukidwe wapamwamba kwambiri, komanso mawonekedwe osavuta opangira.
Ma graphite opangidwa
Kuchulukana kwakukulu, kuyera kwakukulu, kutsika kwa resistivity, mphamvu zamakina apamwamba, kukonza kwamakina, kukana bwino kwa seismic, komanso kukana kutentha kwambiri.Antioxidant dzimbiri.
Kugwedezeka kwa graphite
Kapangidwe ka yunifolomu mu coarse graphite.Mphamvu zamakina apamwamba komanso ntchito yabwino yotentha.Kukula kwakukulu.Angagwiritsidwe ntchito pokonza oversized workpieces
Zimatenga nthawi yayitali bwanji kutchula mawu?
Nthawi zambiri timapereka mawu pasanathe maola 24 titalandira kukula ndi kuchuluka kwazinthuzo.Ngati ndikuyitanitsa mwachangu, mutha kutiyimbira mwachindunji.
Kodi zitsanzo za mayeso zimaperekedwa?
Inde, timapereka zitsanzo kuti muwonetsetse kuti tili ndi khalidwe labwino.Nthawi yoperekera zitsanzo ndi pafupifupi masiku 3-10.Kupatula zomwe zimafunikira makonda.
Kodi nthawi yoyamba yopanga zinthu ndi iti?
Njira yobweretsera imatengera kuchuluka kwake ndipo ndi pafupifupi masiku 7-12.Pazinthu za graphite, chilolezo chogwiritsa ntchito pawiri chiyenera kugwiritsidwa ntchito.
