Amavuta ya Graphite Micro ifu

1. Ibicuruzwa byibanze

Amavuta ya Graphite Micro ifu ni micrometero nini yububiko bwo gukora amavuta yateguwe kuva hejuru - isuku ya flake naturel ya grake cyangwa grafite artificiel binyuze muburyo bwo gusya ultrafine, gusya hejuru - kweza ubushyuhe, no guhindura ubuso (nko guhuza silane hamwe no gutwika aside irike). Agaciro kayo yibanze gushingira kumiterere yihariye ya kristu ya grafite kugirango igere kumikorere ibiri ya "ultra - friction nkeya + ndende - kurinda ijambo". Irashobora gusimbuza amavuta gakondo - ishingiye hamwe n’amavuta ashingiye ku mavuta, igatanga amavuta ahoraho yibikoresho bya mashini mugihe cyakazi gikabije, kandi ifite ibyiza byo kurengera ibidukikije, umwanda - kubuntu, hamwe n’imihindagurikire y’ikirere. Nibikoresho byingenzi byingenzi byo gusiga ibikoresho byo mu nganda no guhindura ibintu.

2.Ibipimo by'ingenzi bya tekiniki

3.Ibiranga ibicuruzwa

(1) Imikorere myiza yo gusiga amavuta

Imodoka ya der der Waals hagati ya grafite igaragara ni ntege nke, kandi kunyerera hagati birashobora kugaragara munsi yimbaraga zo hanze. Coefficient de fraisse irashobora kuba munsi ya 0.05-0.15 (munsi cyane ya 0.3-0.5 ya lisansi gakondo), irashobora kugabanya cyane igipimo cyo kwambara cyibikoresho bya mashini kandi ikongerera igihe cyibikoresho bya serivisi; Ingaruka yo gusiga ntabwo ihindurwa nihindagurika ryumutwaro, kandi iguma ihagaze munsi yumutwaro uremereye (Nturenze cyangwa uhwanye na 50MPa).

(2) Ubushyuhe Bwinshi no Guhuza Ibidukikije

Amavuta ya Graphite Micro ifu irashobora gukora neza murwego rwa dogere -200 (nta buriganya cyangwa gukomera ku bushyuhe buke) kugeza kuri dogere 1200 (mu kirere kitagira inert, nta gushonga cyangwa gutwikwa ku bushyuhe bwo hejuru), kandi irashobora gukoreshwa ku bushyuhe ntarengwa bwa dogere 600 mu kirere. Muri icyo gihe, irwanya ubushuhe n’umukungugu, kandi firime yo gusiga ntabwo byoroshye kunanirwa mugihe cyubushyuhe bwa 80% -95% nubushyuhe bwinshi.

(3) Isuku ryinshi hamwe n’umwanda muke

Icyitegererezo gisanzwe gifite karubone ihamye irenze cyangwa ingana na 99.0%, mugihe icyitegererezo cyo hejuru - gishobora kugera kuri 99,95%, hamwe nivu ryuzuye munsi ya 0.5% (hejuru - iherezo ritarenze cyangwa rihwanye na 0.1%). Irimo umwanda wangiza nka sulfure, gurş, na kadmium, wirinda kwangirika kwibikoresho cyangwa kwanduza ibidukikije, kandi byubahiriza ibipimo by’ibidukikije nka RoHS na REACH.

(4) Gutatanya bihebuje no gufatira hamwe

Nyuma yo kuvura hejuru yubutaka, irashobora gukwirakwizwa kimwe mubitwara nkamavuta yubutare, amavuta yubukorikori, resin, amazi, nibindi, hamwe no gutuza gukomeye kurenza cyangwa bingana namasaha 48 (nta gutuza kugaragara); Kandi ifite imbaraga zifatika hejuru yubutaka nka metero, ceramics, na plastike yubuhanga, hamwe nimbaraga zamavuta ya firime ya Greater irenze cyangwa ingana na 5MPa (ikizamini cya gride), kandi ntishobora gutandukana byoroshye kubera kunyeganyega cyangwa ingaruka.

(5) Imiti ikomeye ihamye

Irwanya kugabanya aside (5% hydrochloric aside, aside sulfurike), kuvanga alkalis (5% sodium hydroxide), hamwe nudukoko twinshi twinshi (Ethanol, acetone, amavuta yubutare), ntabwo ikora imiti hamwe nibitangazamakuru bisanzwe, kandi birashobora gukoreshwa igihe kirekire mubihe byangirika (nkibikoresho bya chimique, imashini zo mu nyanja).

 

 

4. Ibice byingenzi byo gusaba

(1)Gukora imashini no gusiga ibikoresho

Ikora nk'amavuta akomeye yo kwisiga, ibyuma, kuyobora gari ya moshi hamwe na piston impeta munsi yubushyuhe bwo hejuru -, ubushyuhe bwo hejuru - hamwe nuburemere -. Igabanya guterana no kwambara, kandi igasimbuza amavuta yo kwisiga ahantu hakabije nka vacuum.

(2)Metallurgie & Gutunganya ibyuma

Ibikorwa nkibikoresho byo kurekura no gusiga amavuta muguhimba, kuzunguruka no gusohora; byongewe kumashanyarazi yibumba kugirango yongere amavuta nubushuhe bwa slag.

(3)Ibikoresho byo Kuvanga & Sisitemu yo gufata feri

Uzuza urufunguzo rwa feri, isura ya feri ninkweto za feri. Ihindura coefficient de friction, irinda gufunga cyangwa kunyerera, kandi ikongerera ituze sisitemu yo gufata feri.

(4)Amavuta yo kwisiga & Coatings

Imikorere yinyongera yamavuta namavuta kugirango azamure hejuru - ubushyuhe bwo gusiga; yahujwe no kurwanya - kwangirika no kwambara - yihanganira kugira ngo utange amavuta na anti -.

(5)Ingufu nshya & Electronics

Imyitozo ngororamubiri yongerera ingufu za batiri ya lithium kugirango iteze imbere kandi igare neza; gutwikira ibikoresho bya peteroli bipolar plaque kugirango bigabanye guhangana no kongera ruswa.

(6)Gufunga no kubaka ibikoresho

Ibikoresho bibisi bya kashe ya grafite na gasketi ikoreshwa mumiyoboro ya chimique na valve; wongeyeho ibikoresho bitarinda amazi kandi wambare - irwanya igorofa kugirango irusheho kuramba no kurwanya gusaza.

Icyitonderwa

Ingano y'ibice, ubwoko bwo guhindura ibintu (nka hydrophilique ihindura amazi - sisitemu ishingiye hamwe na oleophilic ihindura amavuta sisitemu -), ubuziranenge, nibindi bipimo birashobora gutegurwa ukurikije ibyo abakiriya bakeneye; Tanga raporo yubugenzuzi bufite ireme (COA) kugirango itangwe byinshi, harimo amakuru yapimwe kubipimo byose byavuzwe haruguru.
