arbon chingwe chokongoletsera kuchokera ku mpweya wolimba kwambiri womwe umakhalapo pambuyo pofewetsa, opangidwa ndi mafuta ogulitsa ndi graphite particles, ndi kudzaza voids, kukhala ngati mafuta otupa, ndi kutseka kuphulika
Mitundu yowonongeka imayikidwa ndi kutuluka kwa PTFE komwe kali ndi graphite particles. Kuyambula kuli ndi ubweya wabwino kwambiri.
Zida zogwiritsidwa ntchito zowonongeka kuchokera ku zida zowonongeka zopangidwa ndi PTFE, zopanda mafuta. Mafuta oxidised ali ndi mphamvu zamphamvu komanso zabwino zamtundu wothandizira, PTFE amachititsa kuti phukusi likhale ndi mafuta okwanira kwambiri.
