Njira yaying'ono yoyezera kuchuluka kwa ufa wa graphite

Ma conductivity a ufa wa graphite ndi chinthu chofunika kwambiri popanga zinthu zopangira, choncho ndikofunika kwambiri kuyeza kayendedwe ka ufa wa graphite. The conductivity wa graphite ufa ndi chinthu chofunika kwambiri graphite ufa conductive mankhwala. Pali zinthu zambiri zomwe zimakhudza conductivity ya conductive graphite ufa, monga chiŵerengero cha ufa wa graphite, kuthamanga kwa kunja, chinyezi cha chilengedwe, chinyezi komanso ngakhale kuwala. Nthawi zambiri, njira zotsatirazi zitha kugwiritsidwa ntchito kuyeza kuchuluka kwa ufa wa graphite:

1. Yesani ma conductivity a conductive graphite ufa ndi njira ya utomoni.

Gulani utomoni wa utoto wochititsa chidwi, onjezani ufa wofanana wa conductive graphite, ndiyeno muuveke pa bolodi kuti muyese kusinthasintha kwake ndi multimeter ya digito.

2. Zina zina zoyezera resistivity ya conductive graphite ufa.

Conductivity idzasintha ndi zinthu zakunja, ndipo ndizovuta. Maikolofoni oyambirira onse anali opangidwa ndi ufa wa graphite, chifukwa kugwedezeka kwa phokoso kunasintha kayendedwe kake pakati pa ufa wa graphite, kuti asinthe zamakono ndikupanga zizindikiro za analogi. Ndi zotheka kuti muyenera experimental chilengedwe zofunika kuyeza madutsidwe ake.

3. Kuyeza kukana kwa Voltammetric

Njira yeniyeni: Gwiritsani ntchito mita yamagetsi yaing'ono yokhala ndi miyeso yolondola kapena ma multimeter kuti muyese kusiyanitsa. Mutha kugwiritsa ntchito babu yaying'ono kuti muwone kuwongolera kwake molingana ndi kuwala kwake. Ngati babu ndi wowala, kukana kumakhala kochepa.
