He mineral ʻole ka Bentonite me ka montmorillonite ma ke ʻano he mineral nui. ʻO ke ʻano o ka montmorillonite he ʻano kristal ʻano 2:1 i haku ʻia me ʻelua silicon oxide tetrahedrons i hoʻopili ʻia me kahi papa o ka octahedron alumini oxide. Ma muli o ke ʻano papa i hana ʻia e ke kelepona kristal montmorillonite, aia kekahi mau cations, e like me Cu, Mg, Na, K, a pēlā aku, a ʻo ka pilina ma waena o kēia mau cations a me ke kelepona kristal montmorillonite he paʻa ʻole loa ia, kahi maʻalahi ke hoʻololi ʻia e nā cations ʻē aʻe, no laila he mau waiwai hoʻololi ion maikaʻi kona. 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 ʻia nā kānaka kūloko he pauka lepo bentonite.). Ua hoʻohana nui ʻia no hoʻokahi haneli mau makahiki wale nō. ʻO ka ʻike mua loa ma ʻAmelika Hui Pū ʻIa ma nā papa kahiko o Wyoming, kahi i kapa 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 i ka Montmorillonite ke lawe 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 puʻupuʻu mānoanoa a i ʻole ka lepo wehe, me ka manaʻo pahee ke hamo ʻia me kou mau manamana lima. Ma hope o ka hoʻohui ʻana i ka wai, hoʻonui ke kino liʻiliʻi i nā manawa he nui i 20-30 mau manawa i ka nui, a ʻike ʻia ua kau ʻia i loko o ka wai. Ke liʻiliʻi ka wai, ʻike ʻia he palupalu. Pili nā waiwai o ka montmorillonite i kona ʻano kemika a me kona ʻano kūloko.

Lepo keʻokeʻo kūlohelohe

ʻO ia hoʻi, 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.

ʻO ia ka huahana nui o ka palaho ʻana o ka pōhaku pele vitreous, ʻaʻole e hoʻonui ma hope o ka omo ʻana i ka wai, a ʻo ka waiwai pH o ka hoʻokuʻu ʻana he waikawa nāwaliwali, kahi ʻokoʻa 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 ka poʻe keʻokeʻo maʻemaʻe. Density: 2.7-2.9g/cm2. Haʻahaʻa pinepine ka density ʻike ʻia ma muli o ka 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, kiʻekiʻe ka adsorption. 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.

I ka wā o ka ʻimi ʻana, i ka wā e hana ai i ka loiloi maikaʻi, pono ia e ana i kāna hana bleaching, acidity, filtration performance, omo ʻana o ka aila, a me nā mea ʻē aʻe.

ʻO ka ʻaila Bentonite
He mineral ka ʻaila Bentonite me nā hoʻohana he nui, a ʻo kona ʻano a me nā kahua noi e hilinaʻi nui ʻia i ka ʻano o ka montmorillonite a me kona mau waiwai kemika kristal. No laila, pono e ʻokoʻa kona hoʻomohala ʻana a me ka hoʻohana ʻana mai ka lua a i ka lua a mai ka hana a i ka hana. No ka laʻana, ka hana ʻana o ka pālolo i hoʻāla ʻia, ka calcium i hoʻokumu ʻia i ka sodium, ka wili ʻana i ka grouting no ka wili ʻana i ka petroleum, ka hoʻololi ʻana i ka starch ma ke ʻano he slurry no ka milo ʻana, ka paʻi ʻana a me ka hoʻoluʻu ʻana, ka hoʻohana ʻana i nā uhi paia o loko a me waho ma nā mea kūkulu hale, ka hoʻomākaukau ʻana i ka bentonite organik, ka synthesizing 4A zeolite mai ka bentonite, ka hana ʻana i ka ʻeleʻele kalapona keʻokeʻo, a pēlā aku.

ʻO ka ʻokoʻa ma waena o ka calcium a me ka sodium

Hoʻoholo ʻia ke ʻano o ka bentonite e ke ʻano o ka cation interlayer i loko o ka bentonite. Ke Na+ ka cation interlayer, ua kapa ʻia ʻo ia he sodium based bentonite; Ua kapa ʻia ʻo Calcium based bentonite ke Ca+ ka cation interlayer. ʻOi aku ka maikaʻi o nā waiwai o ka sodium montmorillonite (a i ʻole sodium bentonite) ma mua o ka bentonite calcium based. Eia nō naʻe, ʻoi aku ka laulā o ka hoʻolaha ʻana o ka lepo calcareous ma ka honua ma mua o ka lepo sodium. No laila, me ka hoʻoikaika ʻana i ka ʻimi ʻana i ka lepo sodium, pono e hoʻololi i ka lepo calcareous e lilo i lepo sodium.
