Igisubizo

Sepiolite nubwo ubwoko bwamabuye ya fibre, nicyo kintu cya fibre cyuzuyemo urukuta rwa polyhedrali na pore. Imiterere ya fibre irimo imiterere yumviyeho, igizwe n'ibice bibiri bya SI-O-Si Bond bihujwe na silicon oxide tetrahedron na octahedron irimo magnesium oxide hagati, ikora 0.36 NM. Gusaba inganda za sepiolite mubisanzwe bisabaSepiolite Gusya Urusyo ifu kugirango ibe ubutaka muri se sepiolite. Hcmilling (guini hongcheng) ni uwuba ukora umwuga wa Sepiolite Gusya Urusyo. Urutonde rwose rwibikoresho byacu Sepiolite Gusya Urusyo Umurongo utanga umusaruro wakoreshejwe cyane ku isoko. Murakaza neza kugirango umenye byinshi kumurongo. Ibikurikira ni intangiriro yo gukoresha ifu ya sepiolite:

1. Ibiranga Sepiyolite

(1) Umutungo wa adsorption ya sepiolite

Sepiolite nuburyo bwihariye-bwigice hamwe nubuso bunini bwihariye kandi bwahinduwe na sio2 tetrahedron na mg-o octahedron. Hariho kandi acide nyinshi [Sio4] ibigo bya alkaline [Mgo6] hejuru yacyo, bityo se se seliolite afite imikorere ya adsorption ikomeye.

Imiterere ya Sepiolite ifite ibibuga bitatu bifatika bifatika:

Iya mbere ni anom muri Si-o tetrahedron;

Iya kabiri ni molekile y'amazi zihuza na MG2 + ku nkombe za MG-o Octahedron, cyane cyane zikora hydrogen ifitanye isano n'ibindi bintu;

Iya gatatu ni Si Oh Bond Ihuriro, ikorwa no kumena kwa silicon ogisijeni muri Sio2 tetrahedron no kwakira proton cyangwa hydrocarbone cyangwa molekile cyangwa hydrocarbone cyangwa ubushobozi bwo kwishyura ubushobozi bwabuze. Imwe ya SI yewe muri sedelite irashobora gusabana na molekile ihishe hejuru kugirango ishimangire adsorption, kandi irashobora gukora ubumwe bwa kallsoption hamwe nibintu bimwe na bimwe.

(2) Umutekano wa Sedeli ya Sepiyolite

Sepiolite nigikoresho cyimbaho ​​idasanzwe hamwe no kurwanya ubushyuhe buhamye. Mugihe cyo gushyushya buhoro buhoro kuva mubushyuhe buke kugeza ubushyuhe bwinshi, imiterere ya sepiyolite yanyuze mubyiciro bine byo kugabanya ibiro:

Iyo ubushyuhe bwo hanze bugera ku 100 ℃, molekile y'amazi zimaze gutakaza mu cyiciro cya mbere ni amazi ya zeolite muri porekile, kandi gutakaza iki gice cya molekile y'amazi yose.

Iyo ubushyuhe bwo hanze bugera kuri 130 ℃ kugeza 300 ℃, sepiolite mugice cya kabiri kizatakaza igice cyambere cyamazi yo guhuza hamwe na MG2 +, ni nka 3% ya misa yacyo.

Iyo ubushyuhe bwo hanze bugera kuri 300 ℃ kugeza 500 ℃, sepiolite mucyiciro cya gatatu azabura igice cya kabiri cyamazi yo guhuza Mg2 +.

Iyo ubushyuhe bwo hanze bugera kuri 500 ℃, amazi yibibagi (- Oh) yahujwe na octahedron imbere azabura mu cyiciro cya kane. Imiterere ya fibre ya sepiolite muriki cyiciro yasenyutse rwose, nuko inzira idasubirwaho.

(3) kurwanya ruswa ya sedelite

Sedelite mubisanzwe ifite aside hamwe na alkali. Iyo biri muburyo bwigisubizo ph agaciro <3 cyangwa> 10, imiterere yimbere ya sedelite izaringirwa. Iyo biri hagati ya 3-10, sepiolite yerekana umutekano ukomeye. Irerekana ko sedelite ifite aside ikomeye na alkali, niyihe mpamvu yingenzi ituma se se se se se se se seliolite ikoreshwa nkimbere yimbere yo gutegura maya nk'ingurube y'ubururu.

(4) imiterere ya cataletititique ya sedelite

Sepiolite ni ukwitwara neza kandi neza. Impamvu nyamukuru nuko sedelite irashobora kubona ahantu hihariye hakoreshejwe urwego rwibintu byateganijwe nyuma yo guhindura aside, nibisabwa byiza kugirango ukoreshe se se seliolite nkabatwara. Sedelite irashobora gukoreshwa nkuwitwaye kugirango akore photostlest hamwe na catalytic nziza hamwe na tio2, ikoreshwa cyane muri hydrogenation, okiside, dexication, dexicamisation, nibindi.

(5) Ion Guhana Sepiolite

The ion exchange method uses other metal cations with stronger polarization to replace Mg2+at the end of octahedron in sepiolite structure, thus changing its layer spacing and surface acidity, and enhancing the adsorption performance of sepiolite. Icuti ry'icyuma rya sepiolite ryiganjemo magnesium ion, hamwe na onte ntoya ya aluminium hamwe nandi mato. Ibigize bidasanzwe n'imiterere ya sepiolite yorohereza kuri catitions muburyo bwayo bwo guhana hamwe nibindi bitaje.

(6) imiterere yuburyo bwa sepiyolite

Sedelite ubwayo ninkoni yoroshye, ariko benshi muribo barundanyaga mumitsi hamwe na gahunda idasanzwe. Iyo sepiolite yashonga mumazi cyangwa indi miti ya polan, izi rezo izatatana vuba no gutabara impande zose kugirango ikore umuyoboro wa fibrex na kidasanzwe. Iyi fomu yurusobe ikubiyemo guhagarikwa hamwe nuburyo bukomeye hamwe na viso ndende, byerekana imiterere yihariye ya segolite.

Byongeye kandi, Sepiolite nanone ifite ibiranga insulation, decolorisation, flame redindant no kongera imbaraga, bifite agaciro gakomeye mubikorwa byunganda.

2. Porogaramu nyamukuru ya SedeliteIfu yaSe se selioliteGusya urusyo

Hamwe no guteza imbere byihuse ubukungu bw'Ubushinwa, gusaba isoko ry'imiryango ifasha ibidukikije, ibikoresho byongeweho bifite agaciro. Sedelite nuburyo bwibikoresho bidasanzwe hamwe nubukungu bwiza bitewe nuburyo bwa kirisiti yihariye, bukaba bwanduye, ibidukikije kandi bihendutse. Nyuma yo gutunganywa na imashini yo gusya Sepiolite, irashobora gukoreshwa cyane mu nzego zitandukanye z'inganda, nk'ubwubatsi, Ikoranabuhanga ry'i Ceramic, Synthesis, pestic yo gutunganya ibidukikije, ibidukikije, ibidukikije, n'ibindi, ibidukikije, n'ibindi, ibidukikije Iterambere. Muri icyo gihe, abantu batangiye kwitondera cyane kubisabwa no guteza imbere ikoranabuhanga hamwe niterambere ryikoranabuhanga rya se se seliolite, kandi ryihutisha kubaka urunigi rwinganda rufite imbaraga zo gukemura ikibazo cya sepiolite kumasoko yongeyeho agaciro k'ibicuruzwa.
