I-Polyacrylonitrile esekwe kwiGrafite ifayibha yoluvo

Inkcazo emfutshane:

Igrafayithi yaziva inokwahlulwa ibe yigrafayithi esekwe kwi-asphalt, i-polyacrylonitrile-based (PAN-based) yegraphite yaziva kunye ne-viscose-based grafite yaziva ngenxa yokhetho olwahlukileyo lweemvakalelo zokuqala. Ezona zinto ziphambili zisetyenziswayo xa kusenziwa igrafite Ingasetyenziselwa njengezixhobo zokucoca ulwelo olunobunyulu obunobungozi obunokubangela i-reagent kwimveliso yamachiza.

Iimpawu zemveliso

Igrafayithi yaziva inokwahlulwa ibe yigrafayithi esekwe kwi-asphalt, i-polyacrylonitrile-based (PAN-based) yegraphite yaziva kunye ne-viscose-based grafite yaziva ngenxa yokhetho olwahlukileyo lweemvakalelo zokuqala. Ezona zinto ziphambili zisetyenziswayo xa kusenziwa igrafite Ingasetyenziselwa njengezixhobo zokucoca ulwelo olunobunyulu obunobungozi obunokubangela i-reagent kwimveliso yamachiza.

Inkcazo

I-Polyacrylonitrile esekwe kwiGrafite ifayibha yoluvo yenziwa ngokubeka umgangatho ophezulu wesiseko sekhabhoni esaziva kunyango lwe-pyro-grafayithi. Ukukhanya, ukuguquguquka, kunye nomxholo ophezulu wekhabhoni, inempawu zokushisa okuphezulu, ukumelana nokubola ukumelana nokubola, ukuqhuba ubushushu obuncinci kunye nokugcinwa kwemilo ephezulu.

Ukusetyenziswa

Isetyenzisiwe kulondolozo lobushushu kunye nokungatshi komlilo kwiziko lobushushu eliphezulu, njengeziko elinye lekristale, isithando somlilo se-quartz, iziko lokucoca umlilo, iziko lokungenisa, ubushushu obuphezulu kunye nesilinganisi sobushushu besixhobo, ubushushu bonyango lwesithando somlilo, isithando somlilo, uxinzelelo lweziko njl.

Ingasetyenziswa njengezinto zokucoca ulwelo ezinganyangekiyo kumhlwa.
