Graphite yuzuza ni ibikoresho bikora bigizwe na grafite nkibikoresho byingenzi kandi byongeweho nibindi bikoresho bifasha. Zikoreshwa cyane mugushiraho ikimenyetso, gusiga, gukoresha amashanyarazi, no kurwanya ruswa. Imikorere yibanze ishingiye cyane cyane kubigize no kugereranya ibice byabo byingenzi, cyane cyane ubwiza bwa grafite ubwayo ninyongeramusaruro hamwe.
Igishushanyo: Igice cyingenzi cyibishushanyo mbonera
Igishushanyo nicyo kintu cyibanze cyuzuza grafite, mubisanzwe bigizwe na 60% kugeza 95% byimikorere rusange, hamwe numubare wihariye bitewe nibisabwa. Byombi bisanzwe nibisanzwe birashobora gukoreshwa nkibikoresho fatizo, ariko microstructures hamwe nimiterere biratandukanye. Igishushanyo mbonera gisanzwe (nka flake grafite) gifite imiterere ya kristaliste ifite imiterere ihuza imikoranire idahwitse, bigatuma byoroha kuyisiba, bikavamo amavuta meza -. Ibinyuranyo, ibishushanyo mbonera (nka - ubushyuhe bwabazwe kuri peteroli ya peteroli - ishingiye kuri grafite) muri rusange ni byiza kandi bifite umwanda muke, bigatuma bikenerwa mubisabwa bisaba imiti ihamye.
Imiterere nziza ya Graphite ituma yuzuza intangiriro:
1.
Kwiyitirira - gusiga: Ibice bya Graphite biranyerera byoroshye hagati yabyo, bigabanya kwambara munsi yubushyuhe bwumye cyangwa hasi - amavuta yo kwisiga.
2.
Kurwanya Ubushyuhe Bwinshi: Graphite irashobora gukora neza kugera kuri dogere 450 mukirere ndetse no hejuru ya dogere 3000 muri gaze ya inert.
3.
Imiti ihamye: Graphite yerekana imbaraga nyinshi mubitangazamakuru byinshi bya shimi, usibye aside irike ikomeye (nka acide nitricike yibanze na acide sulfurike).
4.
Imyitwarire: Graphite ifite uburyo bwiza bwa elegitoronike, bigatuma ikwirakwizwa neza cyangwa ikoreshwa rya antistatike.
Ibikoresho bifasha: Urufunguzo rwo Kunoza Imikorere Muri rusange
Nubwo igishushanyo nicyo kintu cyibanze, icyuzuzo cya grafite cyuzuza akenshi guharanira ibyifuzo byimikorere igoye. Kubwibyo, ibikoresho byingirakamaro akenshi byongeweho kugirango bongere imikorere yabo. Ibikoresho bisanzwe bifasha birimo:
1. Binders (nka resin, reberi, cyangwa ibyuma bya okiside)
Binders yongerera imbaraga ubukanishi nuburyo bwo kuzuza ibishushanyo mbonera, bigatuma bikoreshwa muburyo butandukanye bwo gutunganya (nko kubumba, gukuramo, cyangwa kwinjiza). Urugero:
• Ibikoresho bya resin (nka fenolike resin na epoxy resin): Byongera ubukana bwuzuza no kurwanya imiti, bigatuma bibera neza.
• Ibikoresho bya reberi (nka nitrile reberi na fluororubber): Kongera imikorere ihindagurika kandi ikora neza, ikwiranye no gufunga kashe.
• Ibyuma bya okiside (nka okiside ya zinc na aluminium oxyde): Kunoza ubushyuhe bwumuriro hamwe nubushyuhe bukabije -.
2. Gushimangira fibre (nka fibre karubone, fibre yikirahure, na aramide fibre):
Kunoza imbaraga za mashini no kwambara birwanya grafite yuzuza, fibre zishimangira akenshi zongerwaho. Urugero:
• Fibre ya karubone: Ihuza imbaraga nyinshi hamwe nubushyuhe bwo hejuru -, bikwiranye nubushyuhe bwo hejuru - nubushyuhe bwo hejuru - ibidukikije bifunga ibidukikije.
• Fibre fibre: Igiciro gito kandi itezimbere uwuzuza amarira.
• Fibre ya Aramide: Itanga kwambara cyane kandi birwanya imbaraga, bikwiranye nibikorwa bikabije.
3. Amavuta akomeye (nka Molybdenum Disulfide na Polytetrafluoroethylene (PTFE))
Muri bimwe birebire - umutwaro cyangwa hasi - porogaramu yo kwihuta, grafite ntishobora gutanga amavuta ahagije, bityo andi mavuta akomeye yongeweho:
• Molybdenum Disulfide (MoS₂): Imikorere myiza munsi yubushyuhe bwinshi nuburemere bwinshi, akenshi ikoreshwa hamwe na grafite.
• Polytetrafluoroethylene (PTFE): Ifite coefficient nkeya cyane yo guterana amagambo kandi ikwiriye gushyirwaho kashe isaba guterana amagambo make.
Guhindura Ibigize Byuzuye Graphite Yuzuza
Ibigize grafite yuzuza birashobora guhuzwa nibisabwa bitandukanye:
• Ruswa - Irwanya Graphite Yuzuza: Ifu yicyuma nka nikel na feza byongeweho kugirango irusheho kurwanya aside na alkali.
• Kuzuza Graphite Yuzuza: Graphite isukuye iriyongera kandi ifu yumuringa cyangwa carbone nanotube yongerwamo imbaraga kugirango yongere neza.
• High-Purity Graphite Fillers: High-purity (>99%) synthique syntique ikoreshwa mukugabanya umwanda, yujuje ibisabwa ninganda zikoreshwa ninganda za kirimbuzi.
Graphite yuzuza igizwe cyane cyane na grafite, hamwe nibikorwa byanonosowe hifashishijwe siyanse igereranya ibikoresho byingirakamaro nka binders, fibre de fonction, na lubricants. Imikorere ihebuje iterwa n'ubwoko bwa grafite (karemano cyangwa sintetike), ubuziranenge bwayo, no guhitamo ibice bigize ibice. Hamwe niterambere mu ikoranabuhanga mu nganda, ibice byuzuza grafite bizarushaho kunonosorwa kugira ngo byuzuze ibisabwa bikenerwa mu kirere, ingufu n’inganda, hamwe n’ibikoresho byanyuma -.
