Umphumela kanye nenzuzo ebonakalayo yemikhiqizo ye-graphite

Ngenxa yezakhiwo zayo eziningi ezivelele, i-graphite ithola ukusetshenziswa okubanzi emkhakheni we-metallurgical, mechanical, ugesi, amakhemikhali, wendwangu, neminye imikhakha yezimboni. Isebenza njengezinto eziphikisayo futhi igcina izici zamakhemikhali zangempela ze-flake graphite ngenkathi ibonisa izakhiwo eziqinile zokuzigcoba. Impushana ye-graphite ibonakala ngamandla amakhulu ukumelana ne-asidi, ukumelana nokugqwala, ukubekezelela izinga lokushisa eliphezulu kufika ku-3000 ℃ kanye nokumelana nezinga lokushisa eliphansi kuze kufike ku--204 ℃. Ukwengeza, inamandla acindezelayo angaphezu kuka-800kg/Cm2 futhi ikhombisa ukumelana ne-oxidation ngokuncipha kwesisindo okungu-1% kuphela lapho kuvezwe emoyeni ku-450℃. Ngaphezu kwalokho, ikhombisa izinga lokuphindaphinda kwe-15-50% (ukuminyana 1.1-1.5). Ngenxa yalokho, imikhiqizo ye-graphite isetshenziswa kakhulu kwezensimbi, embonini yamakhemikhali, embonini ye-petrochemical, i-high energy physics, i-aerospace, i-electronics neminye imikhakha ehlukahlukene.

Imikhiqizo ye-graphite ngokwayo inezinzuzo ezinkulu kakhulu:

1, imikhiqizo ye-graphite ine-adsorption enhle.

Isakhiwo esingenalutho se-carbon senza i-carbon ibe ne-adsorption enhle, ngakho-ke i-carbon ivame ukusetshenziswa njenge-adsorption material yokumunca amanzi, iphunga, izinto ezinobuthi nokunye. Senze izivivinyo, ezinsukwini ezimbalwa ezedlule izoso esetshenziswa ithreyi lokubhaka i-graphite libukeka lihlanzekile kakhulu, kepha faka ukushisisa kuhhavini lokungeniswa, uzobona ukufakwa kwe-barbecue yokugcina yamafutha nezinto eziyingozi kuzophuma kancane, kodwa ungakhathazeki, nge iphepha lokudla elihlanzekile lokusula lingasetshenziswa.

2, imikhiqizo ye-graphite ine-conductivity enhle yokushisa, ukudluliswa kokushisa okusheshayo, ukushisa okufanayo, ukonga uphethiloli.

Amashidi okubhaka namapani enziwe nge-graphite ashiswa ngokushesha, futhi ukudla okushisiwe kushisa ngokulinganayo, kuphekwe ngaphakathi ngaphandle, futhi isikhathi sokushisa sifushane, hhayi nje ukunambitheka okuhlanzekile, kodwa futhi izakhi zangempela zokudla zingavalwa. . Senze izivivinyo, lapho i-grill pan ye-graphite isetshenziselwa ukugazinga, umpheki we-induction washaya umlilo ekuqaleni, futhi ungashiswa ngamasekhondi angu-20-30 kuphela, futhi lapho ukudla sekuqalisiwe, kungadlalwa umlilo omncane, ongasindisa amandla.

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

I-graphite inokuqina okuhle kwamakhemikhali ekamelweni lokushisa futhi ayihlaselwa yinoma iyiphi i-asidi eqinile, isisekelo esiqinile kanye ne-organic solvent. Ngakho-ke, ngisho noma ukusetshenziswa kwesikhathi eside kwemikhiqizo ye-graphite kungukulahlekelwa okuncane kakhulu, inqobo nje uma kusulwa kuhlanzekile njengokusha.

Imikhiqizo engu-4 ye-graphite ine-anti-oxidation eqinile kanye nomphumela wokunciphisa.

Imikhiqizo, ikakhulukazi ukushisa kwe-mattress ye-graphite ingaveza ama-ion oksijini angalungile, yenze izinto ezizungezile zisebenze, igcine impilo yomuntu, ivimbele ngokuphumelelayo ukuguga, yenza isikhumba sigcwale ukucwebezela nokunwebeka.

5, imikhiqizo ye-graphite impilo yemvelo, akukho ukungcola kwe-radioactive, ukumelana nokushisa okuphezulu.

Ikhabhoni ingaba i-graphite ngemva kwezinsuku okungenani eziyishumi nobusuku be-graphitization endaweni yokushisa ephezulu engu-2000-3300 degrees, ngakho-ke izinto ezinobuthi neziyingozi ku-graphite kade zakhululwa futhi zizinzile ngaphakathi kwamadigri angu-2000 okungenani.

Ngasikhathi sinye, imikhiqizo ye-graphite ngenxa yesakhiwo sayo esikhethekile, enokumelana nokushisa okuphezulu, ukumelana nokushaqeka okushisayo, ukuqhutshwa kukagesi, ukugcotshwa, ukuzinza kwamakhemikhali kanye nepulasitiki kanye nezinye izici eziningi, bekuyinsiza yamasu ebaluleke kakhulu ekuthuthukisweni kwemboni yezempi nesimanje. kanye nobuchwepheshe obuphezulu, obusha nobubukhali, imikhiqizo ye-graphite, njengezindandatho ze-graphite, izikebhe ze-graphite zisetshenziswa kakhulu. Ochwepheshe bamazwe ngamazwe baye babikezela ukuthi "ikhulu lama-20 yikhulu le-silicon, ikhulu lama-21 lizoba yikhulu le-carbon."

Njengomkhiqizo wamasu obalulekile wokumbiwa phansi okungewona owensimbi, imboni ye-graphite izoqaliswa ukuphathwa kokufinyelela. Ngokuqaliswa kwesistimu yokufinyelela, i-graphite, imikhiqizo ye-graphite, izoba enye ngemva komhlaba ongavamile, amakhemikhali e-fluorine, amakhemikhali e-phosphorus, izinkampani ezihamba phambili kulo mkhakha zizongena esigabeni esisha sokuthuthukiswa.
