Nui nā mea kūʻai aku nāna i hana hale kiaʻi i ʻike i nā ʻāpana e koho e hoʻohui pauka hao ultrafine. Akā ʻike paha ʻoe i nā pono o ka hoʻohui ʻana i ka ultrafine Pauda hao?
ʻAʻole pono ka ʻoi aku o ka ʻoi wale nō o ka ʻili hale kiaʻi o kēia lā ma ka mākeke akā he lōʻihi ke ola lawelawe. E lawe i nā ʻili hale kiaʻi i hoʻohana ʻia ma Macheng, ka ʻāina ʻo Hubei ma ke ʻano he laʻana: ʻo kā lākou mau mea ʻoki Dahua granite, Xiaohua granite, Huangjinma granite, etc. ʻO nā ʻano pōhaku ʻelua hope loa me ka abrasiveness kiʻekiʻe e kau i nā koi kiʻekiʻe ma ka hana o nā ʻāpana ʻike.
Nui nā mea kūʻai e hoʻohui i ka pauka hao ultrafine i ka matrix. Hoʻohālikelike ʻia me ka pauka hao maʻamau, ʻoi aku ka maikaʻi o ka pauka hao ultrafine kiʻekiʻe:
- Hoʻohaʻahaʻa ia i ka mahana sintering o ka matrix a hoʻokumu i kahi ʻāpana pre-alloyed me keleawe a me ka tin ma kahi haʻahaʻa haʻahaʻa.
- Hoʻonui ia i ka nui o ka matrix a hoʻonui i ka ikaika paʻa i nā daimana, a laila e hoʻonui i ka hana holoʻokoʻa o ka māhele ʻike.
No laila, ʻo ka hana holoʻokoʻa o ka hale kiaʻi i ʻike i nā ʻāpana i hoʻohui ʻia me ka maʻemaʻe kiʻekiʻe
pauka hao ultrafine ua hoʻomaikaʻi maikaʻi ʻia, hiki ke ʻoki maʻalahi i nā pōhaku me ka abrasive kiʻekiʻe.

E ʻoluʻolu e nīnau no nā kikoʻī hou aku.
