ʻO Bentonite kahi mineral non-metallic i haku nui ʻia me ka montmorillonite.ʻO ka hale montmorillonite he 2:1 ʻano ʻano aniani i haku ʻia me ʻelua silica tetrahedra i kāwili ʻia me kahi papa o ka alumini oxide octahedra.Ma muli o ka papa hana i hoʻokumu ʻia e ka montmorillonite crystal cell, aia kekahi mau cations, e like me Cu, Mg, Na, K, a me nā mea ʻē aʻe, a ʻo kā lākou launa pū ʻana me nā cell crystal montmorillonite he paʻa ʻole, he maʻalahi ke hoʻololi ʻia e nā cations ʻē aʻe. no laila, loaʻa iā lākou nā waiwai hoʻololi ion maikaʻi.Ma nā ʻāina ʻē, ua hoʻohana ʻia ma nā keʻena ʻoi aku ma mua o 100 ma 24 mau kahua o ka hana ʻoihana a me ka mahiʻai, me nā huahana 300, no laila ua kapa ʻia e nā kānaka he "ʻāina honua".

Ua ʻike ʻia ʻo Bentonite he bentonite, bentonite, a i ʻole bentonite.He moʻolelo lōʻihi ko Kina no ka hoʻomohala ʻana a me ka hoʻohana ʻana i ka bentonite, kahi i hoʻohana mua ʻia ma ke ʻano he mea holoi.Aia nā lua hāmama ma Renshou o Sichuan i nā haneli mau makahiki i hala aku nei, a ua ʻōlelo ka poʻe kamaʻāina i ka bentonite ma ke ʻano he lepo lepo.Hoʻohana nui ʻia ia akā aia wale nō ka mōʻaukala ma mua o hoʻokahi haneli mau makahiki.ʻO ka mea i ʻike mua ʻia ma ʻAmelika Hui Pū ʻIa ma ka papa kahiko o Wyoming, kahi i kapa ʻia ai ka pālolo ʻōmaʻomaʻo melemele, hiki ke hoʻonui i loko o kahi paʻi ma hope o ka hoʻohui ʻana i ka wai, i kapa ʻia he bentonite.ʻO ka ʻoiaʻiʻo, ʻo ka ʻāpana mineral nui o ka bentonite he montmorillonite, me kahi ʻike o 85-90%.Hoʻoholo ʻia kekahi mau waiwai o ka bentonite e ka montmorillonite.Hiki ke ʻike ʻia ka Montmorillonite i nā kala like ʻole e like me ka melemele ʻōmaʻomaʻo, melemele keʻokeʻo, hina, keʻokeʻo, a pēlā aku.Hiki iā ia ke hana i nā poloka paʻapū a i ʻole ka lepo ʻūhā, me ka manaʻo paheʻe ke hamo ʻia me nā manamana lima.Ma hope o ka hoʻohui ʻana i ka wai, hoʻonui nui ka nui o nā poloka liʻiliʻi i nā manawa he 20-30, e ʻike ʻia ana i kahi kūlana i hoʻokuʻu ʻia i loko o ka wai, a ma kahi ʻano paʻi i ka wā liʻiliʻi ka wai.ʻO nā waiwai o ka montmorillonite e pili ana i kona haku mele a me ka hoʻolālā o loko.

pālolo hoʻāla ʻia

ʻO ka pālolo i hana ʻia he adsorbent i hana ʻia mai ka pālolo (ʻoi aku ka bentonite) ma ke ʻano he mea maka, i hoʻopaʻa ʻia i ka mālama ʻana i ka acidification inorganic, a ukali ʻia e ka holoi ʻana i ka wai a me ka maloʻo.ʻO kona hiʻohiʻona he waiu keʻokeʻo pauka, ʻala ʻole, ʻono ʻole, ʻaʻohe mea ʻawaʻawa, a loaʻa ka hana adsorption ikaika.Hiki iā ia ke hoʻopili i nā mea kala a me nā mea organik.He maʻalahi ke komo i ka makū i ka lewa, a ʻo ka waiho ʻana no ka lōʻihi loa e hōʻemi i ka hana adsorption.Eia nō naʻe, hoʻomaka ka hoʻomehana ʻana ma luna o 300 degere Celsius e nalowale i ka wai crystalline, e hoʻololi i ke ʻano o ka hana a pili i ka hopena mae.ʻAʻole hiki ke hoʻoheheʻe ʻia ka pālolo i hoʻopaʻa ʻia i ka wai, nā mea hoʻoheheʻe kūlohelohe, a me nā ʻaila like ʻole, aneane hiki ke hoʻoheheʻe ʻia i ka soda caustic wela a me ka waika hydrochloric, me ka mānoanoa pili o 2.3-2.5, a me ka pehu liʻiliʻi i ka wai a me ka ʻaila.

ʻO ka lepo bleached maoli

ʻO ka pālolo keʻokeʻo maoli me nā waiwai bleaching kūlohelohe he pālolo keʻokeʻo keʻokeʻo keʻokeʻo i haku nui ʻia me ka montmorillonite, albite, a me ka quartz, a he ʻano bentonite.
ʻO ka hua nui o ka decomposition o nā pōhaku lua pele aniani, ʻaʻole e hoʻonui ma hope o ka hoʻomoʻa ʻana i ka wai, a ʻokoʻa ka pH waiwai o ka hoʻokuʻu ʻana mai ka bentonite alkaline;ʻOi aku ka maikaʻi o kāna hana bleaching ma mua o ka pālolo hana.ʻO nā waihoʻoluʻu he melemele māmā, ʻōmaʻomaʻo keʻokeʻo, hina, kala ʻoliva, ʻeleʻele, waiu keʻokeʻo, ʻulaʻula peach, uliuli, etc. He kakaikahi nā keʻokeʻo maʻemaʻe.ʻO ka mānoanoa 2.7-2.9g/cm.He haʻahaʻa pinepine ka mānoanoa ʻike ma muli o kona porosity.ʻO ka hui kemika ua like ia me ka pālolo maʻamau, me nā mea kemika nui he alumini oxide, silicon dioxide, wai, a me kahi liʻiliʻi o ka hao, magnesium, calcium, a me nā mea ʻē aʻe. ʻAʻohe plasticity, me ka mana adsorption kiʻekiʻe.Ma muli o kona kiʻekiʻe o ka hydrous silicic acid, he ʻakika ia i ka litmus.Hiki ke pohā ka wai a nui ka wai.ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka fineness, ʻoi aku ka kiʻekiʻe o ka mana decolorization.

ʻOka Bentonite
ʻO Bentonite ore he mineral me nā hoʻohana he nui, a me kona maikaʻi.
