ʻO ka Bentonite he mineral non-metallic me ka montmorillonite ma ke ʻano nui o ka mineral.ʻO ka hale montmorillonite he ʻano ʻano kristal 2:1 i haku ʻia me ʻelua silicon oxygen tetrahedrons i kāwili ʻia me kahi papa o ka alumini oxide octahedron.No ka mea, ʻo ka papa hana i hoʻokumu ʻia e ka montmorillonite cell he mau cations, e like me Cu, Mg, Na, K, etc., a ʻo ke kuleana o kēia mau cations me ka cell montmorillonite he paʻa loa, maʻalahi ke hoʻololi ʻia e nā cations ʻē aʻe, he ion maikaʻi. hiki ke hoololi.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.Hiki ke hoʻonui i ka pālolo chartreuse i ka paʻi ma hope o ka hoʻohui ʻana i ka wai.Ma hope mai, ua kapa nā kānaka i nā pālolo a pau me kēia waiwai he bentonite.ʻO ka ʻoiaʻiʻo, ʻo ka 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 i ka Montmorillonite ke waiho i nā waihoʻoluʻu like ʻole, e like me ka melemele ʻōmaʻomaʻo, melemele keʻokeʻo, hina, keʻokeʻo, a pēlā aku.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 ke ʻano o ka montmorillonite e pili ana i kāna ʻano kemika a me ka hoʻolālā o loko.
