He mineral ʻole-metala ka Bentonite i haku ʻia me ka montmorillonite. ʻO ke ʻano montmorillonite he ʻano kristal ʻano 2:1 i haku ʻia me ʻelua silica tetrahedra i hoʻopili ʻia me kahi papa o ka alumini oxide octahedra. Ma muli o ke ʻano papa i hana ʻia e nā cell kristal montmorillonite, aia kekahi mau cations, e like me Cu, Mg, Na, K, a pēlā aku, a ʻo kā lākou launa pū ʻana me nā cell kristal montmorillonite he paʻa ʻole loa, kahi mea maʻalahi ke hoʻololi ʻia e nā cations ʻē aʻe, no laila he mau waiwai hoʻololi ion maikaʻi ko lākou. Ma waho, ua hoʻohana ʻia ma mua o 100 mau keʻena ma 24 mau kahua o ka hana ʻoihana a me ka mahiʻai, me ka ʻoi aku o 300 mau huahana, no laila ua kapa ʻia ʻo ia he "lepo honua".

Ua kapa ʻia ʻo Bentonite ʻo 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 lua hāmama ma ka ʻāina ʻo Renshou o Sichuan i nā haneli mau makahiki i hala aku nei, a ua kapa nā kamaʻāina i ka bentonite ʻo ka pauka lepo. Hoʻohana nui ʻia akā he moʻolelo wale nō ma mua o hoʻokahi haneli mau makahiki. ʻO ka ʻike mua loa ma ʻAmelika Hui Pū ʻIa ma nā papa kahiko o Wyoming, kahi i kapa pinepine ʻia ai ka lepo melemele ʻōmaʻomaʻo, hiki ke hoʻonui i loko o kahi paʻi ma hope o ka hoʻohui ʻana i ka wai, ʻo ia ka bentonite. ʻO ka ʻoiaʻiʻo, ʻo ka ʻāpana mineral nui o ka bentonite ʻo montmorillonite, me ka ʻike o 85-90%. Hoʻoholo ʻia kekahi mau waiwai o ka bentonite e ka montmorillonite. Hiki ke ʻike ʻia ʻo 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 mānoanoa a i ʻole ka lepo palupalu, me ka manaʻo pahee ke hamo ʻia me nā manamana lima. Ma hope o ka hoʻohui ʻana i ka wai, hoʻonui ʻia ka nui o nā poloka liʻiliʻi i nā manawa he nui i 20-30 mau manawa, e ʻike ʻia ana ma ke ʻano hoʻokuʻu ʻia i loko o ka wai, a ma ke ʻano hoʻopili ke liʻiliʻi ka wai. Pili nā waiwai o ka montmorillonite i kona ʻano kemika a me ke ʻano o loko.

Lepo i hoʻāla ʻia

ʻO ka pālolo i hoʻāla ʻia he mea hoʻopili i hana ʻia mai ka pālolo (ʻo ka bentonite nui) ma ke ʻano he mea maka, kahi i hoʻopili ʻia i ka mālama ʻana i ka acidification inorganic, a ukali ʻia e ka holoi ʻana a me ka hoʻomaloʻo ʻana i ka wai. ʻO kona ʻano he pauka keʻokeʻo waiū, ʻaʻohe ʻala, ʻaʻohe ʻono, ʻaʻohe ʻawaʻawa, a he hana adsorption ikaika. Hiki iā ia ke adsorb i nā mea kala a me nā mea ola. He maʻalahi ke omo i ka makū i ka lewa, a ʻo ke kau ʻana no ka lōʻihi loa e hōʻemi i ka hana adsorption. Eia nō naʻe, ʻo ka hoʻomehana ʻana ma luna o 300 degere Celsius e hoʻomaka ana e nalowale ka wai crystalline, e hoʻoulu ai i nā loli kūkulu a hoʻopilikia i ka hopena mae. ʻAʻole hiki ke hoʻoheheʻe ʻia ka pālolo i hoʻāla ʻia i ka wai, nā mea hoʻoheheʻe organik, a me nā ʻaila like ʻole, kokoke e hoʻoheheʻe loa ʻia i ka soda caustic wela a me ka waikawa hydrochloric, me ka density pili o 2.3-2.5, a me ka pehu liʻiliʻi i ka wai a me ka ʻaila.

Lepo keʻokeʻo kūlohelohe

ʻO ka lepo keʻokeʻo kūlohelohe me nā waiwai hoʻokeʻokeʻo kūlohelohe he lepo keʻokeʻo, hina keʻokeʻo i haku ʻia me ka montmorillonite, albite, a me ka quartz, a he ʻano bentonite ia.
ʻO ka hopena nui o ka palaho ʻana o nā pōhaku pele aniani, ʻaʻole e hoʻonui ma hope o ka omo ʻana i ka wai, a ʻokoʻa ka waiwai pH o ka hoʻokuʻu ʻana mai ka bentonite alkaline; ʻOi aku ka maikaʻi o kāna hana bleaching ma mua o ka lepo i hoʻāla ʻia. ʻO nā kala maʻamau e komo pū me ka melemele māmā, keʻokeʻo ʻōmaʻomaʻo, hina, kala ʻoliva, brown, keʻokeʻo waiū, ʻulaʻula peach, uliuli, a pēlā aku. He kakaikahi loa nā mea keʻokeʻo maʻemaʻe. Density 2.7-2.9g/cm2. Haʻahaʻa pinepine ka density ʻike ʻia ma muli o kona porosity. Ua like ke ʻano kemika me ka lepo maʻamau, me nā mea kemika nui he alumini oxide, silicon dioxide, wai, a me kahi liʻiliʻi o ka hao, magnesium, calcium, a pēlā aku. ʻAʻohe plasticity, me ka hiki ke adsorption kiʻekiʻe. Ma muli o kona nui o ka hydrous silicic acid, he acidic ia i ka litmus. He maʻalahi ka wai i ka haki a he nui ka wai. Ma keʻano laulā, ʻoi aku ka maikaʻi o ka fineness, ʻoi aku ka kiʻekiʻe o ka mana decolorization.

ʻO ka ʻaila Bentonite
He mineral ka ʻaila Bentonite me nā hoʻohana he nui, a me kona ʻano maikaʻi.
