ʻOi aku ka nui o ka magnesium oxide ma nā piliki Magnesia ma mua o 90% a hoʻohana i ka periclase ma ke ʻano he pae crystalline nui. Hiki ke hoʻokaʻawale ʻia nā Piliki Magnesite i ʻelua mau māhele o nā Piliki Magnesia i puhi ʻia a me nā Piliki Magnesite i hoʻopaʻa ʻia me ke kemika. Loaʻa i nā piliki Magnesite ka hana maikaʻi loa o ka ikaika mechanical wela kiʻekiʻe a me ke kūpaʻa o ka leo. A hiki ke lawelawe i ka mahana kiʻekiʻe o 1750 ℃, he huahana kūpono nā piliki Magnesite no ka hoʻopili ʻana i ka umu aniani.
Nā Waiwai o nā Piliki Magnesia
- Nā refractorines kiʻekiʻe,
- Ke kū'ē ʻana i ka ʻōpala alkaline,
- ʻO ke kūpaʻa ʻana i ka ʻino a me ka anti-oxidation maikaʻi loa,
- ʻO ke kūpaʻa kiʻekiʻe ma lalo o ke kaumaha,
- Ikaika mīkini kiʻekiʻe,
- Paʻa ka leo ma ke ana wela kiʻekiʻe.
Kaʻina Hana Hana ʻana o nā Piliki Magnesia
Hiki ke hoʻokaʻawale ʻia nā piliki magnesia i ʻelua ʻano: nā piliki magnesite i puhi ʻia a me nā piliki magnesite i hoʻopaʻa ʻia me nā kemika. Hana ʻia nā piliki magnesite i puhi ʻia mai ka mea maka o ka periclase, ma hope o ke puhi ʻia ʻana me ka mahana kiʻekiʻe 1550 ~ 1600 ℃ ma o ka kuʻi ʻana, ka hoʻohuihui ʻana, ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana. ʻOi aku ka mahana wela o nā huahana maʻemaʻe kiʻekiʻe ma mua o 1750 ℃. Hana ʻia nā piliki magnesite i puhi ʻole ʻia ma ka hoʻohui ʻana i kahi mea kemika kūpono ma o ka hoʻoheheʻe ʻana, ka hoʻoheheʻe ʻana a me ka hoʻomaloʻo ʻana.
Nā Hoʻokaʻawale ʻana o nā Piliki Magnesia
Ma muli o ke ʻano kemika like ʻole o nā piliki magnesia, hiki ke hoʻokaʻawale ʻia i nā ʻano like ʻole, a ua hana ʻia kēia mau piliki āpau ma o ka sintering. Ma muli o nā mea maka like ʻole, hiki ke hoʻokaʻawale ʻia nā piliki magnesia i nā hoʻokaʻawale ʻana penei:
Piliki magnesia maʻamau: pōhaku magnesite sintered.
Piliki magnesia hoʻopaʻa pololei: magnesite sintered maʻemaʻe kiʻekiʻe.
Piliki Forsterite: peridotite
Piliki magnesia calcia: magnesite sintered e loaʻa ana ka calcium kiʻekiʻe.
Piliki silica magnesia: pōhaku magnesite sintered silicon kiʻekiʻe.
Piliki magnesia chrome: magnesite sintered a me kekahi chrome ore.
Piliki alumina magnesia: pōhaku magnesite sintered a me Al2O3.

Ka hoʻohana ʻana i nā pōhaku Magnesia no ka umu ahi
He kūpono nā piliki magnesite no nā ʻano umu wela kiʻekiʻe a pau, e like me nā umu metallurgical. Eia kekahi, hoʻohana nui ʻia nā piliki magnesia i nā lako wela ʻē aʻe, e like me ka umu tunnel hyperthermia, ka uhi o ka umu sima rotary, ka lalo a me ka paia o ka umu hoʻomehana, ke keʻena hoʻōla hou o ka umu aniani, ka lalo a me ka paia o ka umu uila a pēlā aku.
Mea Hana Piliki Magnesia ma KinaM
ʻO ka mea hana pale RS kahi mea hana piliki magnesia ʻoihana ma Kina, hiki ke hāʻawi i nā piliki magnesite kiʻekiʻe nāu. Inā makemake ʻoe i nā piliki magnesia, a i ʻole he mau nīnau kāu e pili ana i nā piliki magnesia e pili ana i nā ʻōuli kino a me ke kemika, e ʻoluʻolu e kelepona mai iā mākou no ka manuahi, e hoʻokaʻaʻike aku kā mākou mea kūʻai aku iā ʻoe i ka wā hikiwawe loa.
