Igisubizo

Sepiolite ni ubwoko bwa minerval ifite fibre, ni fibre fibre igenda isimburana kuva kurukuta rwa polyhedrale nuyoboro wa pore.Imiterere ya fibre irimo imiterere, igizwe nibice bibiri byububiko bwa Si-O-Si bihujwe na silicon oxyde tetrahedron na octahedron irimo oxyde ya magnesium hagati, ikora 0.36 nm × 1.06nm pore yubuki.Sepiolite yinganda zikoreshwa mubisanzweurusyo rwa sepiolite ifu kugirango ibe ifu ya sepiolite.HCMilling (Guilin Hongcheng) ni uruganda rukora umwuga urusyo rwa sepiolite.Ibikoresho byose byacu urusyo rwa sepiolite umurongo wo kubyaza umusaruro wakoreshejwe cyane ku isoko.Murakaza neza kugirango mwige byinshi kumurongo.Ibikurikira nintangiriro yo gukoresha ifu ya sepiolite:

1. Ibyiza bya sepiolite

(1) Indangantego ya sepiolite

Sepiolite ni imiterere-yuburyo butatu ifite ubuso bunini bwubuso bwihariye hamwe nuburinganire bwimbitse, bikozwe na tetrahedron ya SiO2 na octahedron ya Mg-O.Hariho kandi aside nyinshi [SiO4] alkaline [MgO6] hejuru yayo, sepiolite rero ifite imikorere ikomeye ya adsorption.

Sepiolite kristaliste ifite ibice bitatu bitandukanye bya adsorption yibikorwa byikigo:

Iya mbere ni O atom muri Si-O tetrahedron;

Iya kabiri ni molekile y'amazi ihuza na Mg2 + ku nkombe ya Mg-O octahedron, cyane cyane ikora hydrogène hamwe nibindi bintu;

Iya gatatu ni ihuriro rya Si OH, riterwa no kumena umurongo wa ogisijeni wa silicon muri tetrahedron ya SiO2 kandi ugahabwa molekile ya proton cyangwa hydrocarubone kugirango yishyure ubushobozi bwabuze.Umubumbe wa Si OH muri sepiolite urashobora gukorana na molekile zamamajwe hejuru yacyo kugirango zongere imbaraga za adsorption, kandi irashobora gukora imiyoboro ya covalent hamwe nibintu bimwe na bimwe kama.

(2) Ubushyuhe bwumuriro wa sepiolite

Sepiolite ni ibumba ryibumba ridafite imbaraga zo guhangana nubushyuhe bwo hejuru.Mugihe cyo gushyushya buhoro buhoro kuva ubushyuhe buke kugeza ubushyuhe bwinshi, imiterere ya kristu ya sepiolite yanyuze mubyiciro bine byo kugabanya ibiro:

Iyo ubushyuhe bwo hanze bugeze kuri 100 ℃, molekile zamazi sepiolite izabura mugice cya mbere ni amazi ya zeolite mu byobo, kandi gutakaza iki gice cya molekile zamazi bigera kuri 11% byuburemere bwa sepiolite.

Iyo ubushyuhe bwo hanze bugeze kuri 130 ℃ kugeza 300 ℃, sepiolite mugice cya kabiri izabura igice cyambere cyamazi yo guhuza hamwe na Mg2 +, ni hafi 3% yubunini bwayo.

Iyo ubushyuhe bwo hanze bugeze kuri 300 ℃ kugeza 500 ℃, sepiolite mugice cya gatatu izabura igice cya kabiri cyamazi yo guhuza hamwe na Mg2 +.

Iyo ubushyuhe bwo hanze bugeze hejuru ya 500 ℃, amazi yubatswe (- OH) ahujwe na octahedron imbere azabura murwego rwa kane.Imiterere ya fibre ya sepiolite muriki cyiciro yarasenyutse rwose, inzira rero ntisubirwaho.

(3) Kurwanya ruswa ya sepiolite

Sepiolite mubisanzwe ifite aside nziza hamwe na alkali irwanya.Iyo iri murwego hamwe nigisubizo pH agaciro <3 cyangwa> 10, imiterere yimbere ya sepiolite izangirika.Iyo iri hagati ya 3-10, sepiolite yerekana ituze rikomeye.Irerekana ko sepiolite ifite acide ikomeye na anti-alkali, niyo mpamvu yingenzi ituma sepiolite ikoreshwa nkintungamubiri idasanzwe kugirango itegure Maya nka pigment yubururu.

(4) Imiterere ya catalitiki ya sepiolite

Sepiolite ni itwara ibintu bihendutse kandi bifatika.Impamvu nyamukuru nuko sepiolite ishobora kubona ubuso bwihariye bwo hejuru hamwe nuburyo bwayo butandukanye nyuma yo guhindura aside, ibyo bikaba ari ibintu byiza byo gukoresha sepiolite nk'itwara rya catalizator.Sepiolite irashobora gukoreshwa nkubwikorezi kugirango ikore fotokateri ifite imikorere myiza ya catalitiki hamwe na TiO2, ikoreshwa cyane muri hydrogenation, okiside, denitrification, desulfurizasi, nibindi.

(5) Ion guhana sepiolite

Uburyo bwo guhanahana ion bukoresha ibindi byuma hamwe na polarisiyasi ikomeye kugirango isimbuze Mg2 + kumpera ya octahedron mumiterere ya sepiolite, bityo ihindure intera yayo hamwe na acide yo hejuru, kandi byongere imikorere ya adsorption ya sepiolite.Iyoni yicyuma ya sepiolite yiganjemo ioni ya magnesium, hamwe na ion ya aluminiyumu nkeya hamwe nandi mato mato.Imiterere yihariye nuburyo bwa sepiolite byorohereza cations mumiterere yabyo guhana hamwe nizindi cations.

(6) Imiterere yimiterere ya sepiolite

Sepiolite ubwayo nuburyo bworoshye bwinkoni, ariko inyinshi murizo zegeranijwe mumigozi hamwe na gahunda idasanzwe.Iyo sepiolite yashongeshejwe mumazi cyangwa andi mashanyarazi ya polar, iyi bundle izahita ikwirakwira kandi ivangavanga bidahwitse kugirango ibe umuyoboro utoroshye wa fibre hamwe no kugumana bidasanzwe.Iyi miyoboro y'urusobe ikora ihagarikwa hamwe na rheologiya ikomeye hamwe n'ubukonje bwinshi, byerekana imiterere idasanzwe ya rheologiya ya sepiolite.

Byongeye kandi, sepiolite ifite kandi ibiranga insulation, decolorisation, flame retardancy and expansibility, ifite agaciro gakomeye mubikorwa byinganda.

2. Ibyingenzi Byingenzi bya Sepioliteifu ya bySepioliteurusyo

Iterambere ryihuse ry’ubukungu bw’Ubushinwa, isoko ry’ibikoresho byangiza ibidukikije, byongerewe agaciro cyane biriyongera.Sepiolite ni ubwoko bwibintu bidasanzwe kandi bifite umutekano muke bitewe nuburyo bwihariye bwa kirisiti, butarangwamo umwanda, butangiza ibidukikije kandi bihendutse.Nyuma yo gutunganywa na mashini yo gusya ya sepiolite, irashobora gukoreshwa cyane mubikorwa bitandukanye byinganda, nkubwubatsi, ikoranabuhanga ryubutaka, gutegura catalizator, synthesis pigment, gutunganya peteroli, kurengera ibidukikije, plastike, nibindi, bigira ingaruka zikomeye mubikorwa byinganda mubushinwa. iterambere.Muri icyo gihe, abantu batangiye kwita cyane ku guhanga udushya no guteza imbere ikoranabuhanga rya sepiolite, no kwihutisha iyubakwa ry’inganda zikomeye za sepiolite kugira ngo bakemure ikibazo cy’ibura rya sepiolite ku isoko Agaciro kiyongereye ku bicuruzwa.
