ʻO Sepiolite kahi ʻano mineral me ke ʻano fiber, ʻo ia kahi ʻano fiber e hoʻonui ʻia ana mai ka paia pore polyhedral a me ke kahawai pore.Aia i loko o ka hale fiber kahi papa papa, i haku ʻia me ʻelua mau papa o ka paʻa Si-O-Si pili i ka silicon oxide tetrahedron a me ka octahedron i loko o ka magnesium oxide ma waena, e hana ana i ka 0.36 nm × 1.06nm honeycomb pore.Pono ka noi ʻoihana Sepiolitewili wili sepiolite pauda e wili ʻia i pauda sepiolite.ʻO HCMilling(Guilin Hongcheng) he mea hana ʻoihana o wili wili sepiolite.ʻO ka hui holoʻokoʻa o kā mākou wili wili sepiolite ua hoʻohana nui ʻia ka laina hana ma ka mākeke.Welina mai e aʻo hou aku ma ka pūnaewele.Eia ka hoʻolauna ʻana i ka hoʻohana ʻana i ka pauka sepiolite:

1. Na waiwai o ka sepiolite

(1) Adsorption waiwai o sepiolite

ʻO Sepiolite kahi hoʻolālā kūikawā ʻekolu-dimensional me kahi ākea ākea nui a me ka porosity layered, i hoʻopili ʻia e SiO2 tetrahedron a me Mg-O octahedron.Nui nō hoʻi nā kikowaena acidic [SiO4] alkaline [MgO6] ma kona ʻili, no laila he ikaika ka hana adsorption o ka sepiolite.

ʻEkolu mau wahi kikowaena hana adsorption like ʻole: Sepiolite crystal structure:

ʻO ka mua ʻo O atom ma Si-O tetrahedron;

ʻO ka lua, ʻo ia nā molekole wai e hui pū me Mg2+ ma ka lihi o Mg-O octahedron, e hana nui ana i nā paʻa hydrogen me nā mea ʻē aʻe;

ʻO ke kolu, ʻo ia ka hui pū ʻana o Si OH, i hana ʻia e ka haki ʻana o ka paʻa oxygen silicon i ka tetrahedron SiO2 a loaʻa i kahi mole proton a i ʻole hydrocarbon e hoʻopaʻi i ka hiki ke nalowale.Hiki i ka paʻa Si OH i loko o ka sepiolite ke launa pū me nā molekala i hoʻopili ʻia ma luna o kona ʻili e hoʻoikaika i ka adsorption, a hiki ke hana i nā mea paʻa covalent me kekahi mau mea ola.

(2) Paʻa wela o ka sepiolite

ʻO Sepiolite kahi mea pālolo inorganic me ke kūpaʻa kūpaʻa kiʻekiʻe.I loko o ke kaʻina hana hoʻomehana haʻahaʻa mai ka wela haʻahaʻa a hiki i ka wela kiʻekiʻe, ua hele ke ʻano aniani o ka sepiolite i ʻehā mau pae kaumaha.

Ke piʻi ka mahana o waho ma kahi o 100 ℃, ʻo nā molekele wai e lilo ai ka sepiolite i ka pae mua he wai zeolite i loko o nā pores, a ʻo ka nalowale ʻana o kēia ʻāpana o nā molekala wai e hiki i kahi 11% o ka nui o ke kaumaha o ka sepiolite.

Ke piʻi ka mahana o waho i 130 ℃ a 300 ℃, e lilo ka sepiolite i ka lua o ka ʻāpana i ka hapa mua o ka wai hui pū me Mg2+, ʻo ia ka 3% o kona nuipa.

Ke piʻi ka mahana o waho i 300 ℃ a 500 ℃, e nalowale ka sepiolite i ke kolu o ka pae i ka lua o ka wai hui pū me Mg2+.

Ke piʻi ka mahana o waho ma luna o 500 ℃, e nalowale ka wai hana (- OH) i hui pū ʻia me ka octahedron i loko i ka hā o ka pae.Ua luku loa ʻia ke ʻano fiber o sepiolite i kēia pae, no laila ʻaʻole hiki ke hoʻololi ʻia ke kaʻina hana.

(3) Ke pale ʻana i ka corrosion o sepiolite

Loaʻa i ka Sepiolite maoli ka waikawa a me ke kūpaʻa alkali.Aia i loko o ke kikowaena me ka pH solution<3 a i ʻole>10, e ʻino ʻia ke ʻano o loko o ka sepiolite.Aia ma waena o 3-10, hōʻike ka sepiolite i ke kūpaʻa ikaika.Hōʻike ia he ikaika ikaika ka sepiolite a me ke kūpaʻa alkali, ʻo ia ke kumu nui e hoʻohana ʻia ai ka sepiolite ma ke ʻano he kumu inorganic e hoʻomākaukau ai i ka Maya e like me ka puaʻa uliuli.

(4) Nā waiwai catalytic o sepiolite

ʻO Sepiolite kahi mea lawe catalyst maʻalahi a kūpono hoʻi.ʻO ke kumu nui ʻo ia ka hiki ke loaʻa i ka sepiolite kahi ʻāpana kikoʻī kiʻekiʻe a me kona ʻano porous layered ma hope o ka hoʻololi ʻana i ka waikawa, ʻo ia nā kūlana kūpono no ka hoʻohana ʻana i ka sepiolite ma ke ʻano he catalyst carrier.Hiki ke hoʻohana ʻia ʻo Sepiolite ma ke ʻano he mea lawe e hana i kahi photocatalyst me ka hana catalytic maikaʻi loa me TiO2, i hoʻohana nui ʻia i ka hydrogenation, oxidation, denitrification, desulfurization, etc.

(5) Hoʻololi Ion o sepiolite

Hoʻohana ke ʻano hoʻololi ion i nā cations metala ʻē aʻe me ka polarization ikaika e hoʻololi iā Mg2+ ma ka hopena o ka octahedron i loko o ke ʻano sepiolite, pēlā e hoʻololi ai i ka spacing papa a me ka acidity o ka ʻili, a hoʻonui i ka hana adsorption o sepiolite.ʻO nā ion metala o ka sepiolite e hoʻomaluʻia e nā ion magnesium, me kahi liʻiliʻi o nā ion alumini a me kahi liʻiliʻi o nā cations ʻē aʻe.ʻO ka haku mele kūikawā a me ke ʻano o ka sepiolite e maʻalahi i nā cations i kona ʻano e hoʻololi me nā cations ʻē aʻe.

(6) Rheological waiwai o sepiolite

He ʻano koʻokoʻo ʻo Sepiolite ponoʻī, akā ʻo ka hapa nui o lākou e hōʻiliʻili ʻia i loko o nā pūʻulu me ke ʻano ʻole.Ke hoʻoheheʻe ʻia ka sepiolite i loko o ka wai a i ʻole nā ​​​​mea hoʻoheheʻe polar ʻē aʻe, e hoʻopuehu koke kēia mau pūʻulu a hui pū ʻia e hana i kahi ʻupena fiber paʻakikī me ka paʻa ʻole o ka solvent.Hoʻokumu kēia mau pūnaewele i kahi hoʻokuʻu me ka rheology ikaika a me ka viscosity kiʻekiʻe, e hōʻike ana i nā waiwai rheological kūʻokoʻa o sepiolite.

Eia kekahi, loaʻa i ka sepiolite nā hiʻohiʻona o ka insulation, decolorization, flame retardancy a me expansibility, nona ka waiwai noi nui i ka ʻoihana ʻoihana.

2. Nā noi nui o Sepiolitekaʻina pauda eSepiolitewili palaoa

Me ka ulu wikiwiki ʻana o ka hoʻokele waiwai o Kina, ke ulu nei ka makemake o ka mākeke no nā mea pili i ke kaiapuni, nā mea waiwai kiʻekiʻe.ʻO Sepiolite kahi ʻano mea inorganic me ka paʻa maikaʻi ma muli o kāna ʻano aniani kūikawā, ʻaʻohe pollution, ʻoluʻolu a me ka maʻalahi.Ma hope o ka hana ʻia ʻana e ka mīkini wili sepiolite, hiki ke hoʻohana nui ʻia i nā ʻano ʻoihana like ʻole, e like me ka hoʻolālā, ka ʻenehana seramika, ka hoʻomākaukau catalyst, ka pigment synthesis, ka hoʻomaʻemaʻe ʻana i ka ʻaila, ka mālama ʻana i ke kaiapuni, nā plastik, a me nā mea ʻē aʻe. hooulu ana.I ka manawa like, ua hoʻomaka ka poʻe e uku hou aku i ka noiʻi hou a me ka hoʻomohala ʻenehana o sepiolite, a e hoʻolōʻihi i ke kūkulu ʻana i kahi kaulahao ʻoihana sepiolite maʻalahi e hoʻoponopono i ka hemahema o ka sepiolite i kēia manawa ma ka mākeke.
