Copper impregnated graphite wapangidwa ndi graphite ndi mkuwa particles.Pakati pawo, graphite ndi zinthu za carbonaceous, zomwe zingathe kugawidwa mu graphite zachilengedwe ndi graphite yokumba.Mtundu wa kristalo wa graphite wachilengedwe ndi pepala la hexagonal, lokhala ndi crystallinity yayikulu komanso matenthedwe apamwamba kwambiri.Ndi zabwino kwambiri matenthedwe conductivity zakuthupi.The yokumba graphite makamaka anakonza ndi mkulu-kutentha sintering ndi njira zina, ndipo ali ndi makhalidwe a homogeneity wabwino ndi mphamvu mkulu.
Tinthu tating'ono ta mkuwa timaphatikiza mkuwa ndi graphite kudzera m'njira inayake kuti apange graphite yopangidwa ndi mkuwa.Kukhalapo kwa tinthu tating'onoting'ono ta mkuwa sikungowonjezera kusinthika kwa graphite, komanso kumapangitsanso mphamvu ndi kuuma kwake, motero kumawonjezera mawotchi ake komanso kukana kuvala.Komanso, particles mkuwa angathe kuchepetsa resistivity wa graphite ndi bwino matenthedwe madutsidwe.
The mankhwala mitundu ya mkuwa impregnated graphite ndi zosiyanasiyana, amene akhoza kugawidwa mu mbale, chitoliro, ufa ndi mitundu ina.
Plate ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri.Amapangidwa ndi graphite ndi ufa wamkuwa ndi njira yotentha yotentha yotentha.Kuchuluka kwake kumakhala pakati pa 1mm ndi 6mm.Kutalika ndi m'lifupi zikhoza kusinthidwa malinga ndi zosowa zenizeni.Pamwamba pa mbaleyo ndi yosalala komanso yofanana, ndipo imatha kupangidwa, kukonzedwa ndi nkhonya kuti ikwaniritse zosowa za ntchito zosiyanasiyana.
Chitolirocho amapangidwa ndi extrusion pambuyo kusakaniza graphite ndi mkuwa particles.Malo ake amkati ndi akunja ndi osalala komanso ofanana.Itha kukonzedwa ndi mabowo amkati ndi mawonekedwe akunja kuti apange maelekitirodi, ma capacitor, ma transfoma omizidwa ndi mafuta apamwamba kwambiri ndi zida zina.
Ufawu umapangidwa ndi tinthu tating'ono ta graphite ndi mkuwa kudzera munjira yapadera yopera.The tinthu kukula kwa ufa akhoza kusintha malinga ndi zosowa zenizeni.Ili ndi malo ambiri olumikizirana komanso ma conductivity abwino.Itha kugwiritsidwa ntchito kwambiri pazida zamagetsi, zida za batri ndi magawo ena.
Njira yopangira graphite yamkuwa ndiyosavuta, makamaka kuphatikiza izi:
1. Zida zokonzekera: ufa wamkuwa ndi ufa wa graphite udzasakanizidwa mu gawo linalake, ndipo kuchuluka kwa mafuta ndi binder kudzawonjezedwa.
2. Kukonzekera kwa thupi lowumba: kanikizani zinthu zosakanizika mu thupi lowumba loyenera kukonzedwa.
3. Kuyanika ndi kukonza: zimitsani akamaumba, ndiyeno ndondomeko, monga kutembenuza, mphero, kubowola, etc.
4. Sintering: sintering mbali kukonzedwa kupanga olimba mkuwa graphite zakuthupi.
Makhalidwe akuluakulu a graphite yopangidwa ndi mkuwa ndi awa:
(1) Good conductivity: mkuwa impregnated graphite muli zambiri mkuwa particles, zomwe zimapangitsa madutsidwe ake kwambiri.
(2) Good mawotchi katundu: kukhalapo kwa particles mkuwa bwino mphamvu ndi kuuma graphite, kupanga izo ndi katundu wabwino makina.
(3) Good kuvala kukana: kukhalapo kwa particles mkuwa kungathandizenso avale kukana graphite.
(4) Good dzimbiri kukana: graphite palokha ali zabwino dzimbiri kukana.Ndi kuwonjezera kwa tinthu ta mkuwa, kukana kwake kwa dzimbiri ndikwabwino kwambiri.
(5) Good matenthedwe madutsidwe: graphite ndi zabwino matenthedwe madutsidwe zakuthupi.Pambuyo powonjezera tinthu ta mkuwa, matenthedwe ake amatenthedwa bwino.
Mkuwa-impregnated graphite ali madutsidwe kwambiri ndi katundu makina, ndipo chimagwiritsidwa ntchito zipangizo batire, kasamalidwe matenthedwe, zipangizo zamagetsi, makina kupanga ndi madera ena.
Pankhani ya zida za batri, graphite yokhala ndi mkuwa yakhala ikugwiritsidwa ntchito kwambiri pokonzekera mbale za electrode ya batri kuti apititse patsogolo magwiridwe antchito a mabatire chifukwa chamayendedwe ake abwino komanso makina amakina.
M'munda wa kasamalidwe ka matenthedwe, graphite yokhala ndi mkuwa imatha kupangidwa kukhala zipsepse zoyendetsa kutentha kwa kutentha kwa zida zosiyanasiyana zamagetsi.Chifukwa cha kutentha kwake kwabwino kwambiri, imatha kutaya kutentha mwamsanga, motero kuonetsetsa kuti zipangizozi zikugwira ntchito kwa nthawi yaitali.
Pazida zamagetsi, graphite yopangidwa ndi mkuwa ingagwiritsidwe ntchito kupanga ma capacitor, ma transfoma omizidwa ndi mafuta apamwamba kwambiri ndi zida zina.Chifukwa cha kayendedwe kabwino kameneka, imatha kutumiza zizindikiro zamagetsi ndi mphamvu, choncho imatha kukwaniritsa zosowa za zipangizo zosiyanasiyana zamagetsi.
Pamakina opanga makina, ma graphite opangidwa ndi mkuwa amatha kupangidwa kukhala mawonekedwe osiyanasiyana a mbale, mapaipi, ufa, ndi zina zambiri, kuti akwaniritse zosowa zosiyanasiyana zamakina.Panthawi imodzimodziyo, kukana kwake kuvala ndi kukana kwa dzimbiri kumapangitsanso kukhala chinthu choyenera kupanga makina.
