Umuti

Sepiolite ni ubwoko bw'amabuye y'agaciro afite ishusho ya fibre, ikaba ari imiterere ya fibre iva ku rukuta rw'imyobo ya polyhedral n'umuyoboro w'imyobo. Imiterere ya fibre irimo imiterere y'ibice bibiri, igizwe n'ibice bibiri bya Si-O-Si bihujwe na silicon oxide tetrahedron na octahedron birimo magnesium oxide hagati, igakora 0.36 nm × 1.06nm honeycomb pore. Gukoresha Sepiolite mu nganda akenshi bisabauruganda rusya sepiolite ifu igomba gusya ikavamo ifu ya sepiolite. HCMilling (Guilin Hongcheng) ni uruganda rw'umwuga rukora uruganda rusya sepiolite. Ibikoresho byacu byose uruganda rusya sepiolite Umurongo w'umusaruro wakoreshejwe cyane ku isoko. Murakaza neza kugira ngo mumenye byinshi kuri interineti. Ibi bikurikira ni intangiriro ku ikoreshwa ry'ifu ya sepiolite:

1. Imiterere ya sepiolite

(1) Imiterere y'inyunganiramirire ya sepiolite

Sepiolite ni imiterere yihariye ifite ubuso bunini bwihariye n'imyenge y'ibice, iterwamo na tetrahedron ya SiO2 na octahedron ya Mg-O. Hariho kandi ibice byinshi bya aside [SiO4] alkaline [MgO6] ku buso bwayo, bityo sepiolite ifite ubushobozi bwo kuyungurura cyane.

Imiterere ya kristu ya Sepiolite ifite ahantu hatatu hatandukanye ho gushyiramo amazi mu kirere:

Iya mbere ni atome ya O muri tetrahedron ya Si-O;

Icya kabiri ni molekile z'amazi zihuza na Mg2+ ku nkengero za octahedron ya Mg-O, ahanini zikora imigozi ya hydrogen n'ibindi bintu;

Icya gatatu ni uruhurirane rwa Si OH, rukomoka ku gucika k'umugozi wa silicon ogisijeni muri tetrahedron ya SiO2 maze rugahabwa molekile ya protoni cyangwa hydrocarbon kugira ngo isubize ubushobozi bubura. Umugozi wa Si OH muri sepiolite ushobora gukorana n'utunyangingo twinjijwe ku buso bwawo kugira ngo wongere imbaraga zo guhumeka, kandi ushobora gukora imigozi ihuza ibintu bimwe na bimwe by’umwimerere.

(2) Ubushyuhe bwa sepiolite buhamye

Sepiolite ni ibumba ridafite umwimerere rifite ubushobozi bwo guhangana n’ubushyuhe bwinshi. Mu gihe cyo gushyushya buhoro buhoro kuva ku bushyuhe buke kugeza ku bushyuhe bwinshi, imiterere ya kristu ya sepiolite yanyuze mu byiciro bine byo kugabanya ibiro:

Iyo ubushyuhe bwo hanze bugeze kuri dogere 100°C, molekile z'amazi sepiolite izatakaza mu cyiciro cya mbere ni amazi ya zeolite mu myenge, kandi igihombo cy'iki gice cy'amazi kigera kuri 11% by'uburemere bwose bwa sepiolite.

Iyo ubushyuhe bwo hanze bugeze kuri dogere 130 ℃ kugeza kuri dogere 300 ℃, sepiolite mu cyiciro cya kabiri izatakaza igice cya mbere cy'amazi ahuza na Mg2+, ari na byo bigera kuri 3% by'uburemere bwayo.

Iyo ubushyuhe bwo hanze bugeze kuri 300 ℃ kugeza kuri 500 ℃, sepiolite mu cyiciro cya gatatu izatakaza igice cya kabiri cy'amazi ahuza na Mg2+.

Iyo ubushyuhe bwo hanze bugeze hejuru ya 500 ℃, amazi y’imiterere (- OH) ahujwe na octahedron imbere azatakara mu cyiciro cya kane. Imiterere ya fibre ya sepiolite muri iki cyiciro yarasenyutse burundu, bityo inzira ntishobora gusubizwa inyuma.

(3) Ubudahangarwa bwa sepiolite mu kurwanya ingese

Sepiolite mu buryo busanzwe ifite ubushobozi bwo kurwanya aside na alkali. Iyo iri mu buryo bufite pH y'umuti <3 cyangwa>10, imiterere y'imbere ya sepiolite irangirika. Iyo iri hagati ya 3-10, sepiolite igaragaza ubushobozi bwo guhangana. Bigaragaza ko sepiolite ifite ubushobozi bwo kurwanya aside na alkali, ari nayo mpamvu ikomeye ituma sepiolite ikoreshwa nk'ishingiro ry'ibintu bidafite umwimerere mu gutegura Maya nk'ibara ry'ubururu.

(4) Imiterere ya sepiolite mu gukamura

Sepiolite ni catalyst catalyst ihendutse kandi ikora neza. Impamvu nyamukuru ni uko sepiolite ishobora kubona ubuso bwihariye n'imiterere yayo ifite imyenge nyuma yo guhindura aside, ibyo bikaba ari ibintu byiza byo gukoresha sepiolite nk'catalyst catalyst. Sepiolite ishobora gukoreshwa nk'catalyst kugira ngo ikore fotocaliste ifite imikorere myiza ya catalytic hamwe na TiO2, ikoreshwa cyane mu gukwirakwiza hydrogenation, oxidation, denitrification, desulfurization, nibindi.

(5) Ihinduranya rya iyoni rya sepiolite

Uburyo bwo guhinduranya iyoni bukoresha izindi cation z'icyuma zifite polarisation ikomeye kugira ngo zisimbuze Mg2+ ku mpera ya octahedron mu miterere ya sepiolite, bityo bigahindura intera y'urwego rwayo n'ubushyuhe bw'ubuso, kandi byongera imikorere ya sepiolite. Iyoni z'icyuma za sepiolite ziganjemo iyoni za manyeziyumu, hamwe na iyoni nke za aluminiyumu n'izindi cation nke. Imiterere yihariye n'imiterere ya sepiolite bituma byoroha ko cations mu miterere yayo zihinduranya n'izindi cations.

(6) Imiterere ya sepiolite mu mitsi yo mu bwonko

Sepiolite ubwayo ifite ishusho y'inkoni nto, ariko inyinshi muri zo zirundanywa mu matsinda afite gahunda idahwitse. Iyo sepiolite ishongeshejwe mu mazi cyangwa mu bindi binyabutabire byo mu mazi, aya matsinda azahita atandukana vuba kandi avangavanze neza kugira ngo akore urusobe rw'imigozi rugoye kandi rufite ubushobozi bwo kubika imigozi mu buryo butari bwo. Aya matsinda akora ihuriro rifite imiterere ikomeye ya rheology n'ubukana bwinshi, bigaragaza imiterere yihariye ya rheology ya sepiolite.

Byongeye kandi, sepiolite ifite imiterere yo gukingira, gukuraho ibara, kudakoresha umuriro no kwaguka, ikaba ifite akamaro kanini mu nganda.

2. Imikoreshereze y'ingenzi ya Sepioliteifu ikorwa naSepioliteuruganda rusya

Bitewe n’iterambere ryihuse ry’ubukungu bw’Ubushinwa, isoko ry’ibikoresho bibungabunga ibidukikije kandi bifite agaciro kanini ririmo kwiyongera. Sepiolite ni ubwoko bw’ibikoresho bidafite umwimerere bifite umutekano mwiza bitewe n’imiterere yabyo yihariye ya kristu, ikaba idafite umwanda, irinda ibidukikije kandi ihendutse. Nyuma yo gutunganywa n’imashini isya sepiolite, ishobora gukoreshwa cyane mu nganda zitandukanye, nko mu bwubatsi, ikoranabuhanga rya ceramic, gutegura catalysts, gukora irangi, gutunganya peteroli, kurengera ibidukikije, pulasitiki, nibindi, bigira ingaruka zikomeye ku iterambere ry’inganda z’Ubushinwa. Muri icyo gihe, abantu batangiye kwita cyane ku iterambere ry’inganda zikoresha neza sepiolite, kandi bihutisha iyubakwa ry’inganda zigezweho za sepiolite kugira ngo bikemure ikibazo cy’ibura rya sepiolite ku isoko. Agaciro gato k’ibicuruzwa.
