ʻO nā olonā i hana nui ʻia me nā minelala sepiolite ua kapa ʻia he olonā minelala sepiolite. ʻO ka sepiolite kahi minelala olonā silicate waiwai magnesium me kahi ʻano physicochemical o Mgo [Si12O30] (OH) 4 12 H2O. ʻEhā mau mole wai he wai crystalline, ʻo ke koena he wai zeolite, a loaʻa pinepine nā mea liʻiliʻi e like me ka manganese a me ka chromium.

Loaʻa iā Sepiolite ka adsorption maikaʻi, decolorization, thermal stability, corrosion resistance, radiation resistance, thermal insulation, friction resistance, a me ke komo ʻana, a hoʻohana nui ʻia i ka ʻeli ʻana, petroleum, lāʻau lapaʻau, hana pia, nā mea kūkulu hale, nā pesticides, nā mea hoʻouluulu, nā huahana rubber, braking, a me nā mahina ʻē aʻe.

ʻO nā koi no nā olonā mineral sepiolite ma kekahi mau kahua penei:

ʻO ka nui o ka hoʻokahe kala ʻana he ≥ 100%, ʻo ka nui o ka pulping he >4m3/t, a ʻo ka wikiwiki o ka hoʻopuehu ʻana, ʻekolu manawa o ka asbestos. ʻO ke kiko heheʻe he 1650 ℃, ʻo ka viscosity he 30-40s, a hiki ke palaho maoli me ka ʻole o ka hana ʻana i ka haumia. ʻO ia ka lua o ka manaʻo o ka hoʻolālā aupuni i kākoʻo nui ʻia e ka ʻāina, kahi i hoʻopili piha ʻia ma nā ʻāina ʻē a ua ʻike ʻia ʻo ia he fiber mineral ʻōmaʻomaʻo.

1. ʻAʻohe haumia o ka hoʻohana ʻana i ka sepiolite ma ke ʻano he huahana laholio, me ka hana sila maikaʻi loa a me ke kūpaʻa ʻakika kiʻekiʻe.

2. ʻO ka hana ʻana me ka sepiolite e hopena i ʻehiku manawa ʻoi aku ka nui o ka hoʻokaʻawale ʻana o ke kala a me ka hoʻomaʻemaʻe ʻana o ka wai ma mua o ka asbestos.

3. ʻO ka hoʻohana ʻana i ka sepiolite no ka friction he elasticity maikaʻi, paʻa ka paʻakikī o ka hoʻopuehu ʻana, a he 150 mau manawa ka nui o ka omo ʻana o ke kani ma mua o ka asbestos. He haʻahaʻa loa ke kani friction, a he mea waiwai nui ia no ka loaʻa kālā ma waho aku.

ʻO ka fiber Sepiolite kahi fiber mineral kūlohelohe, he ʻano fibrous o ka mineral sepiolite a ua kapa ʻia ʻo α-Sepiolite. Wahi a nā loea, ʻo ka sepiolite, ma ke ʻano he mineral silicate kaulahao papa, he ʻāpana hoʻonohonoho papa 2:1 i haku ʻia me ʻelua papa o ka silicon oxygen tetrahedra i hoʻopaʻa ʻia e kahi papa o ka magnesium oxygen octahedra. Hoʻomau ka papa tetrahedral, a ke hoʻololi pinepine ʻia nei ke kuhikuhi ʻana o nā ʻano oxygen reactive i loko o ka papa. Hoʻokumu nā papa octahedral i nā kahawai i hoʻonohonoho ʻia ma waena o nā papa o luna a me lalo. Kūlike ke kuhikuhi ʻana o ke kahawai me ke axis fiber, e ʻae ana i nā mole wai, nā cations metala, nā mole liʻiliʻi organik, a me nā mea ʻē aʻe e komo i loko. Loaʻa iā Sepiolite ka pale wela maikaʻi, ka hoʻololi ion a me nā waiwai catalytic, a me nā waiwai maikaʻi loa e like me ke kūpaʻa ʻana i ka corrosion, ke kūpaʻa ʻana i ka radiation, ka insulation, a me ka insulation thermal. ʻOi loa, hiki i ka Si-OH i loko o kona ʻano ke hana pololei me nā mea organik e hana i nā derivatives mineral organik.

I loko o kona ʻāpana hoʻonohonoho, hoʻololi ka silicon oxide tetrahedra a me ka magnesium oxide octahedra kekahi i kekahi, e hōʻike ana i nā ʻano hoʻololi o nā ʻano papa a me nā kaulahao. Loaʻa iā Sepiolite nā waiwai kino a me nā kemika kūikawā, me kahi ʻāpana ʻili kikoʻī kiʻekiʻe (a hiki i 800-900m2/g), kahi porosity nui, a me nā hiki adsorption a me catalytic ikaika.

He ākea loa nā kahua noi o ka sepiolite, a ma hope o kekahi mau ʻano lapaʻau e like me ka hoʻomaʻemaʻe ʻana, ka hana ʻana i ka ultra-fine, a me ka hoʻololi ʻana, hiki ke hoʻohana ʻia ka sepiolite ma ke ʻano he adsorbent, mea hoʻomaʻemaʻe, deodorant, mea hoʻoikaika, mea hoʻomaha, mea thixotropic, mea hoʻopiha, a pēlā aku ma nā ʻano ʻoihana e like me ka mālama ʻana i ka wai, catalysis, rubber, coatings, fertilizers, feed, etc. Eia kekahi, ʻo ke kūpaʻa paʻakai maikaʻi a me ke kūpaʻa wela kiʻekiʻe o ka sepiolite e hoʻolilo iā ia i mea lepo wili kiʻekiʻe i hoʻohana ʻia i ka wili petroleum, ka wili geothermal, a me nā kahua ʻē aʻe.
