ʻO nā hōʻailona ʻenehana o ka micro powder kiʻekiʻe kiʻekiʻe e pili ana i ka hoʻohele ʻana i ka nui o ka ʻāpana, ke ʻano o ka ʻāpana, ka maʻemaʻe, nā waiwai kino a me nā ʻāpana ʻē aʻe, e pili pono ana i kāna hopena noi i nā ʻano ʻoihana like ʻole (e like me ka polishing, grinding, cutting, etc.). ʻO kēia nā hōʻailona ʻenehana koʻikoʻi a me nā koi i hoʻokaʻawale ʻia mai nā hopena hulina piha.
Māhele ʻāpana nui a me nā ʻāpana kikoʻī
1. Laulā nui o nā ʻāpana
He 0.1-50 microns ka nui o ka pauka daimana microns, a ʻokoʻa nā koi no ka nui o nā ʻāpana i nā ʻano noiʻi like ʻole.
Hoʻomaʻamaʻa: E koho i ka 0-0.5 micron i ka 6-12 micron o ka pauka liʻiliʻi e hōʻemi i nā ʻōpala a hoʻomaikaʻi i ka hoʻopau ʻana o ka ʻili 5
ʻO ka wili: ʻoi aku ka maikaʻi o ka micro-powder mai 5-10 microns a 12-22 microns no ka maikaʻi a me ka maikaʻi o ka ʻili.
ʻO ka wili maikaʻi: 20-30 micron pauka hiki ke hoʻomaikaʻi i ka hana wili
2. Ka hoʻohelehele ʻana i ka nui o ka particle
D10: ʻo ka nui o ka nui o 10% o ka puʻunaue kumulative, e hōʻike ana i ka hapa o nā ʻāpana maikaʻi. Pono e hoʻomalu ʻia ka hapa o nā ʻāpana maikaʻi e pale i ka hōʻemi ʻana o ka pono wili.
D50 (median diameter): hōʻike i ka awelika ka nui o ka ʻāpana, ʻo ia ke ʻano kumu o ka puʻunaue ʻana i ka nui o ka nui a pili pono i ka hana pono a me ka pololei.
D95: ʻO ka nui o ka nui o ka 95% cumulative distribution, a me ka mālama ʻana i ka ʻike o nā ʻāpana koʻikoʻi (e like me D95 ma mua o ka maʻamau e maʻalahi ke kumu i nā ʻōpala ma nā mea hana).
Mv (ka nui awelika o ka nui): ua hoʻopilikia nui ʻia e nā ʻāpana nui a hoʻohana ʻia e loiloi i ka puʻunaue hope loa
3. Pūnaehana maʻamau
ʻO nā maʻamau o ka honua i hoʻohana mau ʻia me ANSI (eg D50, D100) a me ISO (eg ISO6106:2016).
ʻO ka lua, ke ʻano o ka ʻāpana a me nā hiʻohiʻona o ka ʻili
1. Hoʻohālikelike ʻano
ʻO ka pōʻai: ʻoi aku ka kokoke o ka pōʻai i ka 1, ʻoi aku ka spherical o nā ʻāpana a ʻoi aku ka maikaʻi o ka hopena polishing; ʻoi aku ka maikaʻi o nā ʻāpana me ka pōʻai haʻahaʻa (nui nā kihi) no ka hoʻoheheʻe ʻana i nā uwea uila a me nā hiʻohiʻona ʻē aʻe e pono ai nā kihi ʻoi.
ʻO nā ʻāpana like-plate: ʻo nā ʻāpana me ka transmittance> 90% i manaʻo ʻia e like me ka pā, a ʻo ka hapa e emi iho ma mua o 10%; ʻO ka nui o nā ʻāpana e like me ka pā e alakaʻi i ka deviation o ka ʻike ʻana i ka nui o ka nui a me ka hopena noi paʻa ʻole.
ʻO nā ʻāpana like me ka bead: ʻo ka lōʻihi a me ka laulā ākea o nā ʻāpana> 3: 1 pono e hoʻomalu pono ʻia, a ʻaʻole pono ka hapa ma mua o 3%.
2. ʻAno ʻike ʻano
Microscope Optical: kūpono no ka nānā ʻana i ke ʻano o nā ʻāpana ma luna o 2 microns
ʻIke ʻia ka microscope electron (SEM): hoʻohana ʻia no ka nānā ʻana i ka morphology o nā ʻāpana ultrafine ma ka pae nanometer.
Ka hoʻomaʻemaʻe a me ka haumia
1. Maʻiʻo haumia
Pono e hoʻomaʻemaʻe daimana ma> 99%, a me nā mea haumia metala (e like me ka hao, ke keleawe) a me nā mea ʻino (sulfur, chlorine) pono e mālama pono ʻia ma lalo o 1%.
Pono e haʻahaʻa nā haumia magnetic e pale aku i ka hopena o ka agglomeration ma ka poli pololei.
2. Mākēneki maʻalahi
ʻO ke daimana maʻemaʻe kiʻekiʻe e pili kokoke i ka non-magnetic, a ʻo ke kiʻekiʻe magnetic susceptibility e hōʻike i ke koena o nā metala haumia, pono e ʻike ʻia e ke ʻano induction electromagnetic.
Nā hōʻailona hana kino
1. Paʻakikī paʻakikī
Hōʻike ʻia ke kūpaʻa ʻana o nā ʻāpana e ka wikiwiki ʻole (a i ʻole nā manawa semi-cracked) ma hope o ka hoʻāʻo ʻana i ka hopena, e pili pono ana i ka lōʻihi o nā mea hana wili.
2. Paʻa wela
Pono ka pauka maikaʻi e mālama i ka paʻa i ke kiʻekiʻe o ka wela (e like me 750-1000 ℃) i mea e pale ai i ka hoʻokumu ʻana o ka graphite a i ʻole ka oxidation e hoʻemi ai i ka ikaika; ʻike maʻamau i ka thermogravimetric analysis (TGA).
3. Microhardness
ʻO ka microhardness o ka pauka daimana a hiki i ka 10000 kq / mm2, no laila pono e hōʻoia i ka ikaika ʻāpana kiʻekiʻe e mālama i ka ʻoki ʻana.
Nā koi hoʻololi pono 238
1. Kaulike ma waena o ka hoʻolaha ʻana i ka nui o ka ʻāpana a me ka hopena o ka hoʻoili ʻana
ʻO nā ʻāpana koʻikoʻi (e like me D95 kiʻekiʻe) e hoʻomaikaʻi i ka maikaʻi o ka wili ʻana akā e hōʻemi i ka pau ʻana o ka ʻili: ʻoi aku ka hopena o nā ʻāpana maikaʻi (D10 liʻiliʻi). E hoʻoponopono i ka laulā e like me nā koi.
2. Hoʻololi kino
He kūpono nā ʻāpana ʻāpana he nui no nā huila wili resin; kūpono nā ʻāpana spherical no ka polū pololei.
Nā ʻano hoʻokolohua a me nā kūlana
1. ʻIke nui ʻāpana
Laser diffraction: hoʻohana nui ʻia no nā micron/submicron particles, hana maʻalahi a me ka ʻikepili hilinaʻi;
ʻO ke ala kānana: pili wale i nā ʻāpana ma luna o 40 microns;
2. ʻIke kino
Hiki i ka mea kālai kiʻi ʻāpana ke helu i nā ʻāpana e like me ka sphericity a hoʻemi i ka hewa o ka nānā lima;
hōʻuluʻulu
Pono ka micro-powder daimana kiʻekiʻe i ka hoʻomalu piha ʻana ma luna o ka puʻunaue ʻana i ka nui o nā ʻāpana (D10/D50/D95), ke ʻano o nā ʻāpana (ka poepoe, ka flake a i ʻole ka maʻi kui), ka maʻemaʻe (nā haumia, nā waiwai magnetic), a me nā waiwai kino (ikaika, paʻa wela). Pono nā mea hana e hoʻopaʻa i nā ʻāpana e pili ana i nā hiʻohiʻona noiʻi kikoʻī a hōʻoia i ka maikaʻi mau ma o nā ʻano e like me ka laser diffraction a me electron microscopy. I ke koho ʻana, pono nā mea hoʻohana e noʻonoʻo i nā koi hoʻoponopono kikoʻī (e like me ka maikaʻi a me ka hoʻopau) a hoʻohālikelike i nā hōʻailona e like me ia. No ka laʻana, pono e hoʻolalelale i ka D95 a me ka pōʻai, ʻoiai ʻo ka wili ʻana e hoʻomaha i nā koi e hoʻonui ai i ka pono.
Hoʻopuka ʻia ka ʻike ma luna mai ka pūnaewele superhard material.
