KODI CHIFUKWA CHIYANI ZINTHU ZA CARBON ZIYENERA KUBWEREDWA MIMBA, NDIPO KOMANSO ZOKHUDZA KUBADWA NDI CHIYANI?

Zida za carbon ndi za porous. The porosity okwana mankhwala carbon ndi 16% ~ 25%, ndi graphite mankhwala ndi 25% ~ 32%. Kukhalapo kwa ma pores ambiri mosakayikira kudzakhala ndi zotsatirapo zoyipa pazakuthupi ndi zamankhwala komanso magwiridwe antchito a carbon. Mwachitsanzo, pakuwonjezeka kwa porosity, kuchuluka kwa zinthu za kaboni kumachepa, mphamvu yolimbana nayo imawonjezeka, mphamvu zamakina zimachepa, kukana kwa mankhwala ndi dzimbiri kumawonongeka, komanso kutulutsa mpweya ndi zakumwa kumawonjezeka. Chifukwa chake, pazida zina zogwira ntchito kwambiri za kaboni ndi zida zomangira kaboni, compaction ya impregnation iyenera kukhazikitsidwa.

Zolinga zotsatirazi zitha kukwaniritsidwa kudzera mu impregnation ndi chithandizo cha compaction:
(1) kuchepetsa kwambiri porosity ya mankhwala;
(2) Kuchulukitsa kachulukidwe kazinthu ndikuwongolera mphamvu zamakina azinthu:
(3) Kusintha magetsi ndi matenthedwe madutsidwe a mankhwala;
(4) Kuchepetsa permeability wa mankhwala;
(5) Kupititsa patsogolo kukana kwa okosijeni ndi kukana kwa dzimbiri kwa chinthucho;
(6) Kugwiritsa ntchito lubricant impregnation kumatha kupititsa patsogolo kukana kwa chinthucho.
Zotsatira zoyipa za impregnation ndi kachulukidwe wa zinthu za kaboni ndikuti coefficient ya kukula kwamafuta kumawonjezeka pang'ono.
