Ubwino wa zida za graphite ndi zinthu zotenthetsera zamagetsi za ng'anjo ya vacuum

Ndi kusintha kwa mlingo wa ng'anjo yochizira vacuum vacuum, chithandizo cha kutentha kwa vacuum chili ndi ubwino wapadera, ndipo chithandizo cha kutentha kwa vacuum chakondedwa ndi anthu ogwira ntchito chifukwa cha ubwino wambiri monga degassing, degreasing, oxygen free and automation. Komabe, n'zochititsa chidwi kuti ng'anjo vacuum kutentha mankhwala ali ndi muyezo wapamwamba wa zinthu Kutentha magetsi, monga mkulu-kutentha mapindikidwe, fracture Volatilization wakhala chinthu chofunika kuletsa chitukuko cha.ng'anjo ya vacuum.
Pofuna kuthetsa vutoli, makampaniwa adatembenukira ku graphite.Graphiteamapangidwa ndi zitsulo zina ndipo ali ndi ubwino wosaneneka. Zikumveka kuti graphite ndi pafupifupi wotchuka mitundu yosiyanasiyana ya ng'anjo vacuum kutentha mankhwala monga magetsi Kutentha element.
Ndiye ubwino wa graphite vakuyumu kutentha mankhwala magetsi Kutentha zinthu
1) Kukana kutentha kwakukulu: malo osungunuka a graphite ndi 3850 ± 50 ℃ ndi malo otentha ndi 4250 ℃. Ngakhale atawotchedwa ndi ultra-high kutentha kwa arc, kulemera kwake kumakhala kochepa kwambiri ndipo coefficient of thermal expansion ndi yaying'ono kwambiri. Mphamvu ya graphite imawonjezeka ndi kuwonjezeka kwa kutentha. Pa 2000 ℃, mphamvu ya graphite imawirikiza kawiri.
2) Conductivity ndi matenthedwe madutsidwe: madutsidwe wa graphite ndi nthawi 100 apamwamba kuposa zitsulo ambiri sanali zitsulo. Kutentha kotentha kumaposa chitsulo, chitsulo, lead ndi zinthu zina zachitsulo. The matenthedwe madutsidwe amachepetsa ndi kuwonjezeka kutentha. Ngakhale kutentha kwambiri, graphite imakhala insulator. Graphite imatha kuyendetsa magetsi chifukwa atomu iliyonse ya kaboni mu graphite imapanga zomangira zitatu zokha ndi zinakabonima atomu, ndipo atomu iliyonse ya kaboni imakhalabe ndi elekitironi imodzi yaulere kuti isamutsidwe.
3) Lubricity: ntchito yamafuta a graphite imadalira kukula kwa sikelo ya graphite. Kukula kwa sikelo, kumachepetsa kugundana kwapakati, komanso momwe mafuta amagwirira ntchito bwino. Kukhazikika kwa Chemical:graphiteimakhala ndi kukhazikika kwamankhwala bwino kutentha kwa chipinda ndipo imatha kukana asidi, alkali ndi dzimbiri zosungunulira za organic.
4) Pulasitiki: graphite imakhala yolimba kwambiri ndipo imatha kupangidwa kukhala mapepala owonda kwambiri. Thermal shock resistance: graphite ikagwiritsidwa ntchito kutentha kwa firiji, imatha kupirira kusintha kwakukulu kwa kutentha popanda kuwonongeka. Kutentha kukasintha mwadzidzidzi, kuchuluka kwa graphite kumasintha pang'ono ndipo ming'alu sichitika.
Popanga ndi kukonza ng'anjo ya vacuum, tiyenera kuganizira kuti kukana kwa chinthu chotenthetsera chamagetsi kumasintha pang'ono ndi kutentha ndipo resistivity imakhala yokhazikika, kotero graphite ndiye chinthu chomwe chimakondedwa.
