Kupanga ndi kusankha ufa wa graphite

Ufa wa graphite ndi chinthu chosakhala chachitsulo chokhala ndi mankhwala abwino kwambiri komanso zinthu zakuthupi. Chimagwiritsidwa ntchito kwambiri popanga mafakitale. Chimasungunuka kwambiri ndipo chimatha kupirira kutentha kopitilira 3000 °C. Kodi tingasiyanitse bwanji ubwino wawo pakati pa ufa wosiyanasiyana wa graphite? Mkonzi wotsatira wa graphite wa Furuite akufotokoza njira yopangira ndi kusankha ufa wa graphite:

Kapangidwe ka mankhwala a ufa wa graphite pa kutentha kwa chipinda ndi kokhazikika, kosasungunuka m'madzi, asidi wochepa, alkali wochepa ndi organic solvent, wokhala ndi kukana kutentha kwabwino, kukana kutentha kwambiri komanso kukana dzimbiri. Ufa wa graphite ungagwiritsidwe ntchito ngati chinthu choletsa ma electrode mabatire. Njira yopangira ndi yovuta kwambiri. Mchere wosaphika umafunika kuphwanyidwa ndi chotsukira mwala, kenako kuyandama ndi mphero ya mpira, kenako n’kuphwanyidwa ndikusankhidwa ndi mphero ya mpira. Zinthu zonyowa zomwe zasankhidwa zimayikidwa m’thumba ndikutumizidwa ku Dry mu chowumitsira. Zinthu zonyowa zimayikidwa mu workshop yowumitsira kuti ziume, ndipo zimauma ndikuyikidwa m’thumba, womwe ndi ufa wamba wa graphite.
Ufa wa graphite wabwino kwambiri uli ndi mpweya wambiri, kuuma kwake ndi 1-2, umagwira ntchito bwino kwambiri, uli ndi khalidwe labwino, wofewa, imvi yakuda, wonenepa, ndipo ukhoza kuipitsa pepalalo. Tinthu tating'onoting'ono tikakhala tating'ono, chinthu chokonzedwacho chidzakhala chosalala. Komabe, sikuti tinthu tating'onoting'ono tikakhala tating'ono, ufa wa graphite umagwira ntchito bwino. Furuite Graphite imakumbutsa aliyense kuti ndi chinsinsi chopeza ufa woyenera wa graphite womwe ukugwirizana ndi zosowa zanu ndikupanga magwiridwe antchito okwera mtengo.
