Feldspar: Mea Pono Pono Pohaku a me Kona Hana Hana Hana

ʻO Feldspar kekahi o nā koʻikoʻi koʻikoʻi o ka hoʻokumu ʻana i ka pōhaku i ka ʻōpala o ka honua.Hoʻohana nui ʻia ka potasium a i ʻole ka sodium-rich feldspar i nā seramika, enamel, aniani, abrasives, a me nā ʻāpana ʻoihana ʻē aʻe.ʻO ka potassium feldspar, ma muli o kona kiʻekiʻe o ka pāhare pāpaʻa a ʻo ia ka wai-wai-soluble punawai, hiki ke hoʻohana ʻia i ka wā e hiki mai ana no ka hana ʻana i nā mea kanu potash, e lilo ia i kumu waiwai koʻikoʻi koʻikoʻi.Hiki i nā Feldspar ke loaʻa nā mea laʻa e like me ka rubidium a me ka cesium ke lilo i kumu mineral no ka unuhi ʻana i kēia mau mea.Hiki ke hoʻohana ʻia nā feldspar ʻulaʻula nani e like me nā pōhaku hoʻonaninani a me nā pōhaku makamae.

Ma waho aʻe o ka lilo ʻana i mea waiwai no ka ʻoihana aniani (e pili ana i ka 50-60% o ka nui o ka hoʻohana ʻana), hoʻohana ʻia ka feldspar i ka ʻoihana seramika (30%), me ke koena i hoʻohana ʻia i nā kemika, abrasives, fiberglass, welding electrodes, a me nā ʻoihana ʻē aʻe.

Holoi aniani
ʻO Feldspar kekahi o nā mea nui o nā hui aniani.Me ka Al₂O₃ kiʻekiʻe a me ka haʻahaʻa haʻahaʻa hao, hoʻoheheʻe ʻo feldspar ma kahi haʻahaʻa haʻahaʻa a loaʻa kahi ākea heheʻe.Hoʻohana nui ʻia ia e hoʻonui i ka ʻike alumina i loko o nā hui aniani, e hoʻemi i ka mahana hoʻoheheʻe, a hoʻonui i ka ʻike alkali, pēlā e hoʻemi ai i ka nui o ka alkali i hoʻohana ʻia.Hoʻohui hou, hoʻoheheʻe mālie ʻo feldspar i ke aniani, pale i ka hana ʻana o nā kristal e hiki ke hōʻino i ka huahana.Kōkua ʻo Feldspar i ka hoʻoponopono ʻana i ka viscosity o ke aniani.ʻO ka maʻamau, hoʻohana ʻia ka potassium a i ʻole ka sodium feldspar i nā hui aniani like ʻole.

ʻO nā mea hana kino keramika
Ma mua o ke kī ʻana, hana ʻo feldspar ma ke ʻano he mea hoʻoheheʻe ʻia, e hōʻemi ana i ka hoʻomaloʻo ʻana a me ka deformation o ke kino, e hoʻomaikaʻi i ka hana maloʻo, a me ka pōkole o ka manawa maloʻo.I ka wā o ke kī ʻana, hana ʻo feldspar ma ke ʻano he flux e hoʻohaʻahaʻa i ka mahana ahi, e hoʻoikaika ana i ka hoʻoheheʻe ʻana o ka quartz a me kaolin, a me ka hoʻomaʻamaʻa ʻana i ka hana ʻana o ka mullite i ka pae wai.ʻO ke aniani feldspar i hana ʻia i ka wā e hoʻoheheʻe ʻia e hoʻopiha i nā kīʻaha kristal mullite i loko o ke kino, e hoʻomāhuahua ai a hōʻemi i ka porosity, a laila e hoʻonui ai i kona ikaika mechanical a me nā waiwai dielectric.Hoʻohui ʻia, hoʻonui ka hoʻokumu ʻana o ke aniani feldspar i ka translucency o ke kino.ʻO ka nui o ka feldspar i hoʻohui ʻia i nā kino seramika e like me nā mea maka a me nā koi huahana.

ʻAiʻi Ceramic
Hoʻokumu ʻia ka ceramic glaze me ka feldspar, quartz, a me ka pālolo, me ka ʻike feldspar mai 10-35%.I ka ʻoihana seramika (ke kino a me ka glaze), hoʻohana nui ʻia ka potassium feldspar.

Na Waiwai Kino a Kimia
ʻO Feldspar kahi minerala nui i loaʻa ma ka honua, me ka nui o ka potassium feldspar i kapa ʻia ʻo ka potassium feldspar, i hoʻohālikelike ʻia me ka KAlSi₃O₈.ʻO Orthoclase, microcline, a me sanidine nā mineral feldspar potassium.Loaʻa i kēia mau feldspars ke kūpaʻa kemika maikaʻi a kūpaʻa maʻamau i ka decomposition acid.Loaʻa iā lākou ka paʻakikī o 5.5-6.5, kahi umekaumaha kikoʻī o 2.55-2.75 t / m³, a me kahi helu heheʻe o 1185-1490 ° C.ʻO nā minela pili maʻamau, ʻo ia ka quartz, muscovite, biotite, beryl, garnet, a me nā mea liʻiliʻi o ka magnetite, columbite, a me tantalite.

Hoʻokaʻawale i nā waihona Feldspar
Hoʻokaʻawale ʻia nā waihona Feldspar i ʻelua ʻano ma muli o kā lākou genesis:

1. **Gneiss a i ʻole Migmatitic Gneiss**: Loaʻa kekahi mau aʻa i loko o ka granite a i ʻole nā ​​pōhaku kumu, a i ʻole ma ko lākou mau wahi pili.Hoʻopili nui ʻia ka ʻai i loko o ka feldspar block zone o nā pegmatites a i ʻole nā ​​​​pegmatites feldspar differentiated.

2. ** Nā Waihona Feldspar ʻAno Pōhaku Igneous**: Aia kēia mau waihona i loko o nā pōhaku ʻakika, waena, a me ka alkaline.ʻO nā mea i loaʻa i loko o nā pōhaku alkaline ka mea nui loa, e like me ka nepheline syenite, a ukali ʻia e ka granite, albite granite, orthoclase granite, a me quartz orthoclase granite deposits.

Ma muli o ke kaʻina hana mineralization o feldspar, ua hoʻokaʻawale ʻia nā waihona feldspar i nā ʻano pōhaku igneous, ʻano pegmatite, ʻano granite weathered, a me nā ʻano pōhaku sedimentary, me nā ʻano pegmatite a me nā ʻano pōhaku igneous ka mea nui.

Nā Hana Hoʻokaʻawale
- **Kōʻulu Manaʻo**: Ma muli o nā ʻokoʻa ʻokoʻa o ke ʻano a me ka waihoʻoluʻu mai nā mineral gangue ʻē aʻe, hoʻohana ʻia ka hoʻokaʻawale lima.
- **Hoʻokaʻawale Magnetic**: Ma hope o ka ʻohi ʻana a me ka wili ʻana, hoʻohana ʻia nā mea hoʻokaʻawale magnetic e like me ka plate magnetic separator, LHGC vertical ring high gradient magnetic separator, a me HTDZ electromagnetic slurry magnetic separator e hoʻoneʻe i ka hao hao palupalu, titanium, a me nā minerala haumia ʻē aʻe. no ka hoomaemae ana.
- **Flotation**: Hoʻohana nui ʻia ka HF acid ma lalo o nā kūlana acidic, me nā amine cations ma ke ʻano he ʻohi no ka hoʻokaʻawale ʻana i ka feldspar mai ka quartz.

No ka ʻike hou aku e pili ana i nā mea hoʻokaʻawale magnetic Huate a pehea e hiki ai iā lākou ke kōkua i ka hoʻomaʻemaʻe a me ka hoʻokaʻawale ʻana i nā feldspar a me nā minerala ʻē aʻe, e kipa i kā mākou pūnaewele.Hāʻawi ʻo Huate Magnetic Separator i nā hopena hoʻokaʻawale magnetic kiʻekiʻe i kūpono i kāu mau pono ʻoihana.
