Ikiganiro kigufi kijyanye n'ikoranabuhanga rya pome ya diyama yo mu rwego rwo hejuru

Ibipimo bya tekinike byerekana ifu ya diyama yo mu rwego rwo hejuru ikubiyemo gukwirakwiza ingano y’ibice, imiterere y’ibice, ubuziranenge, ibintu bifatika n’ibindi bipimo, bigira ingaruka ku buryo butaziguye mu bikorwa bitandukanye mu nganda (nko gusya, gusya, gukata, n'ibindi). Ibikurikira nibyingenzi byingenzi bya tekinike nibisabwa byatoranijwe bivuye mubisubizo byubushakashatsi byuzuye:

Ingano nini yo gukwirakwiza no kuranga ibipimo
1. Ingano yubunini
Ingano yubunini bwa pome ya diyama mubusanzwe ni microne 0.1-50, kandi ibisabwa mubunini buke biratandukanye cyane muburyo butandukanye bwo gukoresha.
Kuringaniza: Hitamo micron 0-0.5 kugeza kuri micron ya 6-12 ya poro ya micro kugirango ugabanye gushushanya no kunoza ubuso bwa 5
Gusya: Micro-ifu iri hagati ya microne 5-10 kugeza kuri microne 12-22 irakwiriye muburyo bwiza ndetse nubuziranenge bwubuso.
Gusya neza: ifu ya micron 20-30 irashobora kunoza imikorere yo gusya
2. Ingano nini yo gukwirakwiza ibiranga
D10: ingano yingero zingana zingana na 10% yikwirakwizwa ryinshi, byerekana igipimo cyibice byiza. Umubare wibice byiza bigomba kugenzurwa kugirango wirinde kugabanuka neza.
D50.
D95: ingano ihwanye nubunini bwa 95% yo gukwirakwiza, no kugenzura ibiri mubice bito (nka D95 irenze igipimo cyoroshye gutera ibishushanyo kumurimo).
Mv (ingano yubunini buringaniye): yibasiwe cyane nuduce twinshi kandi ikoreshwa mugusuzuma ikwirakwizwa ryanyuma
3. Sisitemu isanzwe
Ibipimo mpuzamahanga bikunze gukoreshwa harimo ANSI (urugero D50, D100) na ISO (urugero ISO6106: 2016).
Icya kabiri, imiterere y'ibice n'ibiranga ubuso
1. Imiterere y'ibipimo
Kuzenguruka: uko uruziga ruri hafi ya 1, niko uduce duto duto duto kandi ningaruka nziza yo gusya; ibice bifite uruziga ruto (impande nyinshi) birakwiriye cyane kuri electroplating wire wongeyeho nandi mashusho akeneye impande zikarishye.
Ibice bisa nibisahani: ibice bifite transmitance> 90% bifatwa nkibisahani, kandi igipimo kigomba kuba munsi ya 10%; birenze urugero bisa nkibice bizaganisha ku gutandukana kwingero zingana no kumenya ingaruka zidahinduka.
Ibice bisa nisaro: uburebure bwubugari bwikigereranyo cyibice> 3: 1 bigomba kugenzurwa cyane, kandi igipimo ntigomba kurenga 3%.
2. Uburyo bwo gutahura uburyo
Microscope optique: ikwiranye no kureba imiterere yibice biri hejuru ya microne 2
Gusikana microscope ya electron (SEM): ikoreshwa mugusesengura morphologie yibice bya ultrafine kurwego rwa nanometero.
Kugenzura isuku no guhumana
1. Ibirimo umwanda
Isuku ya diyama igomba kuba> 99%, naho umwanda wibyuma (nkicyuma, umuringa) nibintu byangiza (sulfure, chlorine) bigomba kugenzurwa cyane munsi ya 1%.
Umwanda wa magneti ugomba kuba muke kugirango wirinde ingaruka za agglomeration kuri polishinge neza.
2. Ibyoroshye bya rukuruzi
Diyama isukuye cyane igomba kuba hafi ya magnetiki, kandi kwanduza magnetiki kwinshi kwerekana umwanda wibyuma bisigaye, bigomba gutahurwa nuburyo bwo kwinjiza amashanyarazi.
Ibipimo byerekana imikorere
1. Ingaruka zikomeye
Kurwanya kumenagura ibice birangwa nigipimo kitavunitse (cyangwa ibihe byacitse) nyuma yikizamini cyingaruka, bigira ingaruka kuburyo burambye bwibikoresho byo gusya.
2. Guhagarara neza
Ifu nziza ikeneye kugumya gutuza mubushyuhe bwinshi (nka 750-1000 ℃) kugirango wirinde gukora grafite cyangwa okiside bigatuma imbaraga zigabanuka; bikunze gukoreshwa isesengura rya thermogravimetric (TGA) gutahura.
3. Microhardness
Microhardness yifu ya diyama igera kuri 10000 kq / mm2, bityo rero birakenewe ko imbaraga zingirakamaro zogukomeza gukora neza.
Ibisabwa byo guhuza n'imihindagurikire y'ikirere 238
1. Kuringaniza hagati yubunini bwikwirakwizwa ningaruka zo gutunganya
Ibice bito (nka D95 yo hejuru) biteza imbere gusya ariko bigabanya kurangiza hejuru: ibice byiza (bito D10) bigira ingaruka zinyuranye. Hindura urwego rwo gukwirakwiza ukurikije ibisabwa.
2. Kurwanya imiterere
Hagarika ibice byinshi-bikwiranye no gusya inziga; uduce duto duto dukwiranye neza.
Uburyo bwo gupima
1. Kugaragaza ingano yubunini
Gutandukanya Laser: bikoreshwa cyane kuri micron / submicron ibice, imikorere yoroshye namakuru yizewe;
Uburyo bwo gushungura: gusa bikoreshwa mubice biri hejuru ya microni 40;
2. Kugaragaza imiterere
Isesengura ryibice bigize isesengura rishobora kugereranya ibipimo nkuburinganire no kugabanya ikosa ryo kwitegereza intoki;

incamake
Ifu nziza ya diyama nziza cyane isaba kugenzura byimazeyo gukwirakwiza ingano (D10 / D50 / D95), imiterere yibice (kuzenguruka, flake cyangwa inshinge), ubuziranenge (umwanda, ibintu bya magneti), nibintu bifatika (imbaraga, ituze ryumuriro). Ababikora bagomba guhitamo ibipimo bishingiye kumiterere yihariye yo gusaba no kwemeza ubuziranenge buhoraho binyuze muburyo nka laser diffaction na microscopi ya electron. Mugihe uhitamo, abakoresha bagomba gutekereza kubisabwa gutunganywa (nkibikorwa no kurangiza) hanyuma bagahuza ibipimo bikurikije. Kurugero, gutunganya neza bigomba gushyira imbere kugenzura D95 no kuzenguruka, mugihe gusya bikabije bishobora koroshya imiterere kugirango byongere imikorere.
Ibirimo byavuzwe haruguru byakuwe murusobe rwibikoresho bya superhard.
