Ungayithatha kanjani induku ye-graphite?

I-thermal conductivity kanye ne-conductivity kagesi yezinduku ze-graphite ziphakeme kakhulu, futhi ukuqhutshwa kwawo kagesi kuphakeme izikhathi ezi-4 kunezinsimbi ezingenasici, izikhathi ezi-2 ngaphezu kwe-carbon steel, futhi izikhathi ezingu-100 ziphakeme kunezingezona ezensimbi ezijwayelekile. I-conductivity yayo eshisayo ayidluli nje kuphela insimbi, insimbi, umthofu nezinye izinto zensimbi, kodwa futhi iyancipha ngokunyuka kwezinga lokushisa, elihlukile ezintweni ezijwayelekile zensimbi. Emazingeni okushisa aphakeme kakhulu, i-graphite ingashisa ngisho nokushisa. Ngakho-ke, izakhiwo zokushisa ezishisayo ze-graphite zithembeke kakhulu emazingeni okushisa aphezulu kakhulu.

Induku ye-graphite

Izinduku ze-graphite zivame ukusetshenziselwa ukukhishwa kwe-electrothermal kumaziko okushisa aphezulu okushisa. Izinga lokushisa eliphakeme lokusebenza lingafinyelela ku-3000, futhi kulula ukuba i-oxidized emazingeni okushisa aphezulu. Ngaphandle kwe-vacuum, angasetshenziswa kuphela endaweni engathathi hlangothi noma enciphisayo.

Ngenxa yezakhiwo zayo ezinhle kakhulu, i-graphite isetshenziswa kabanzi emikhakheni ehlukahlukene futhi ingasetshenziswa njengento ephikisayo.

Imikhiqizo ye-graphite igcina izakhiwo zamakhemikhali zangempela ze-flake graphite futhi inezici eziqinile zokuzigcoba. I-graphite powder ibonakala ngamandla amakhulu, ukumelana ne-asidi, ukumelana nokugqwala, ukumelana nokushisa okuphezulu nokuphansi.

I-graphite inokuqina okuhle kwamakhemikhali ekamelweni lokushisa futhi ayigqwali yinoma iyiphi i-asidi eqinile, isisekelo esiqinile kanye ne-organic solvent, ngakho-ke ngisho noma isetshenziswe isikhathi eside, ukulahlekelwa kwemikhiqizo ye-graphite kuncane kakhulu, inqobo nje uma isulwa ihlanzekile. , iyafana nentsha.
