Umphumela kanye nenzuzo yezinto ezibonakalayo zemikhiqizo ye-graphite

Ngenxa yezakhiwo zayo eziningi ezivelele, i-graphite isetshenziswa kabanzi emikhakheni yensimbi, yemishini, kagesi, yamakhemikhali, yendwangu, kanye neminye imikhakha yezimboni. Isebenza njengento evimbela ukugqwala futhi igcina izici zamakhemikhali zokuqala ze-graphite ye-flake ngenkathi ibonisa izakhiwo eziqinile zokuzigcoba. I-Graphite powder ibonakala ngokumelana ne-asidi enamandla aphezulu, ukumelana nokugqwala, ukubekezelela amazinga okushisa aphezulu afinyelela ku-3000℃ kanye nokumelana nokushisa okuphansi afinyelela ku--204℃. Ngaphezu kwalokho, inamandla okucindezela adlula u-800kg/Cm2 futhi ikhombisa ukumelana ne-oxidation ngokulahlekelwa isisindo okungu-1% kuphela uma ivezwa emoyeni ku-450℃. Ngaphezu kwalokho, ikhombisa izinga lokubuyela emuva elingu-15-50% (ubuningi obungu-1.1-1.5). Ngenxa yalokho, imikhiqizo ye-graphite isetshenziswa kakhulu ekubumbeni insimbi, embonini yamakhemikhali, embonini ye-petrochemical, kwi-physics yamandla aphezulu, ezindizayo, kuma-electronics nakwamanye amasimu ahlukahlukene.

Imikhiqizo ye-Graphite ngokwayo inezinzuzo ezinkulu kakhulu:

1, imikhiqizo ye-graphite inomuncu omuhle.

Isakhiwo sekhabhoni esingenalutho senza ikhabhoni ibe nokumuncwa okuhle, ngakho-ke ikhabhoni ivame ukusetshenziswa njengento yokumuncwa yokumuncwa kwamanzi, iphunga, izinto ezinobuthi njalo njalo. Senze izivivinyo, ezinsukwini ezimbalwa ezedlule ithreyi yokubhaka ye-graphite esetshenzisiwe ibukeka ihlanzekile kakhulu, kodwa faka i-induction oven heating, uzobona ukuthi ukumuncwa kokugcina kwe-braai kwamafutha nezinto eziyingozi kuzophuma kancane kancane, kodwa ungakhathazeki, nephepha lokudla elihlanzekile lokusula lingasetshenziswa.

2, imikhiqizo ye-graphite inokushisa okuhle, ukudluliselwa kokushisa okusheshayo, ukushisa okufanayo, ukonga uphethiloli.

Amashidi okubhaka namapani enziwe nge-graphite ashiswa ngokushesha, futhi ukudla okushisiwe kushiswa ngokulinganayo, kuphekwe ngaphakathi kuya ngaphandle, futhi isikhathi sokushisa sifushane, hhayi nje kuphela ukuthi ukunambitheka kuhlanzekile, kodwa futhi nezakhamzimba zokuqala zokudla zingavalwa. Senze izivivinyo, lapho ipani lokugcoba le-graphite lisetshenziselwa ukosa, isitofu sokungenisa sishisa umlilo ekuqaleni, futhi singashiswa ngemizuzwana engama-20-30 kuphela, futhi lapho ukudla sekuqalile, kungadlalwa emlilweni omncane, ongasindisa amandla.

3, imikhiqizo ye-graphite inokuqina kwamakhemikhali kanye nokumelana nokugqwala.

I-Graphite inamandla amakhemikhali kahle ekushiseni kwegumbi futhi ayihlaselwa yinoma iyiphi i-asidi enamandla, isisekelo esiqinile kanye nesinyibilikisi sezinto eziphilayo. Ngakho-ke, noma ngabe ukusetshenziswa kwesikhathi eside kwemikhiqizo ye-graphite akunakulahlekelwa okukhulu, inqobo nje uma isuliwe njengentsha.

Imikhiqizo emi-4 ye-graphite inomphumela oqinile wokulwa ne-oxidation kanye nokunciphisa.

Imikhiqizo, ikakhulukazi ukushisa komatrasi we-graphite ingakhiqiza ama-ion e-oxygen angemihle, yenze izinto ezizungezile zisebenze, ilondoloze impilo yabantu, ivimbele ukuguga ngempumelelo, yenze isikhumba sigcwale ukukhazimula nokunwebeka.

5, imikhiqizo ye-graphite impilo yezemvelo, akukho ukungcola okunemisebe, ukumelana nokushisa okuphezulu.

Ikhabhoni ingaba yi-graphite ngemva kwezinsuku nobusuku obuyishumi nambili be-graphitization endaweni yokushisa ephezulu yama-degrees angu-2000-3300, ngakho-ke izinto ezinobuthi neziyingozi ku-graphite sezikhishwe isikhathi eside futhi zizinzile ngaphakathi kwama-degrees okungenani angu-2000.

Ngesikhathi esifanayo, imikhiqizo ye-graphite ngenxa yesakhiwo sayo esikhethekile, enokumelana nokushisa okuphezulu, ukumelana nokushaqeka kokushisa, ukuhanjiswa kukagesi, ukuthambisa, ukuzinza kwamakhemikhali kanye nokuqina kwepulasitiki kanye nezinye izici eziningi, ibilokhu iyinsiza ebalulekile ekuthuthukisweni kwemboni yezempi neyesimanje futhi ubuchwepheshe obuphezulu, obusha nobubukhali, imikhiqizo ye-graphite, njengendandatho ye-graphite, izikebhe ze-graphite zisetshenziswa kabanzi. Ochwepheshe bamazwe ngamazwe babikezele ukuthi "ikhulu lama-20 liyikhulu le-silicon, ikhulu lama-21 lizoba yikhulu le-carbon."

Njengomkhiqizo obalulekile wezokumbiwa phansi ongeyona insimbi, imboni ye-graphite izosetshenziswa ukuphathwa kokufinyelela. Ngokusetshenziswa kohlelo lokufinyelela, i-graphite, imikhiqizo ye-graphite, izoba enye ngemuva kwe-rare earth, i-fluorine chemical, i-phosphorus chemical, izinkampani ezihamba phambili kulo mkhakha zizongena esigabeni esisha sentuthuko.
