Isisombululo

I-Sepiolite luhlobo lweminerali ene-fiber form, eyi-fiber structure ephuma ngokuhlukileyo ukusuka kwi-polyhedral pore wall kunye ne-pore channel.Ulwakhiwo lwefayibha lunesakhiwo esinemaleko, esakhiwe ngamacandelo amabini e-Si-O-Si bond edibeneyo i-silicon oxide tetrahedron kunye ne-octahedron equlethe i-magnesium oxide phakathi, eyenza i-0.36 nm × 1.06nm pore yobusi.Ukusetyenziswa kweshishini le-Sepiolite ngokuqhelekileyo kufunailitye lokusila i-sepiolite umgubo wokuculwa ube ngumgubo we-sepiolite.I-HCMilling(Guilin Hongcheng) ngumvelisi oyingcali we ilitye lokusila i-sepiolite.Iseti yonke yezixhobo zethu ilitye lokusila i-sepiolite umgca wemveliso usetyenziswe ngokubanzi kwimarike.Wamkelekile ukuba ufunde ngakumbi kwi-intanethi.Oku kulandelayo kukwazisa ukusetyenziswa kwe-sepiolite powder:

1. Iipropati ze-sepiolite

(1) Iimpawu ze-Adsorption ze-sepiolite

I-Sepiolite sisakhiwo esikhethekileyo esine-dimensional ezintathu kunye nommandla omkhulu ocacileyo kunye ne-porosity elayishiwe, ehlonyelwe yi-SiO2 tetrahedron kunye ne-Mg-O octahedron.Kukho amaziko amaninzi ane-acidic [SiO4] alkaline [MgO6] kumphezulu wayo, ngoko ke i-sepiolite inokusebenza okunamandla kwe-adsorption.

Isakhiwo sekristale se-Sepiolite sineendawo ezintathu ezahlukeneyo ze-adsorption kwiziko elisebenzayo:

Eyokuqala yi-O athom eseSi-O tetrahedron;

Eyesibini ziimolekyuli zamanzi ezinxibelelana neMg2+ kumda we-Mg-O octahedron, ikakhulu zenza iibhondi zehydrogen nezinye izinto;

Okwesithathu yindibaniselwano yebhondi ye-Si OH, eyenziwa ngokuphulwa kwebhondi ye-silicon oksijini kwi-tetrahedron ye-SiO2 kwaye ifumana i-proton okanye i-hydrocarbon molekyuli ukubuyisela amandla angekhoyo.Ibhondi ye-Si OH kwi-sepiolite inokusebenzisana kunye neemolekyuli ezibhengezwe kumphezulu wayo ukuqinisa i-adsorption, kwaye inokwenza i-covalent bonds kunye nezinto ezithile eziphilayo.

(2) Ukuzinza kwe-thermal ye-sepiolite

I-Sepiolite yinto yodongwe engabonakaliyo kunye nokumelana nokushisa okuphezulu okuzinzileyo.Ngexesha lenkqubo yokufudumeza ngokuthe ngcembe ukusuka kubushushu obuphantsi ukuya kubushushu obuphezulu, ubume bekristale be-sepiolite budlule kwizigaba ezine zokulahleka kobunzima:

Xa ubushushu bangaphandle bufikelela malunga ne-100 ℃, iimolekyuli zamanzi eziza kulahlekelwa yi-sepiolite kwinqanaba lokuqala ziyi-zeolite yamanzi kwi-pores, kwaye ilahleko yale nxalenye yeemolekyuli zamanzi ifikelela malunga ne-11% yobunzima be-sepiolite.

Xa izinga lokushisa langaphandle lifikelela kwi-130 ℃ ukuya kwi-300 ℃, i-sepiolite kwinqanaba lesibini liya kulahlekelwa yinxalenye yokuqala yamanzi okulungelelanisa kunye ne-Mg2 +, malunga ne-3% yobunzima bayo.

Xa ubushushu bangaphandle bufikelela kwi-300 ℃ ukuya kwi-500 ℃, i-sepiolite kwinqanaba lesithathu liya kulahlekelwa yinxalenye yesibini yamanzi okulungelelanisa kunye ne-Mg2 +.

Xa ubushushu bangaphandle bufikelela ngaphezu kwe-500 ℃, amanzi akhiweyo (- OH) adityaniswe ne-octahedron ngaphakathi aya kulahleka kwinqanaba lesine.Ukwakhiwa kwefiber ye-sepiolite kweli nqanaba kutshatyalaliswe ngokupheleleyo, ngoko ke inkqubo ayinakuguqulwa.

(3) Ukuxhatshazwa kwe-Corrosion ye-sepiolite

I-Sepiolite ngokwemvelo ine-asidi efanelekileyo kunye nokumelana ne-alkali.Xa iphakathi kunye nexabiso le-pH isisombululo <3 okanye> i-10, isakhiwo sangaphakathi se-sepiolite siya kugqwala.Xa kuphakathi kwe-3-10, i-sepiolite ibonisa ukuzinza okuqinileyo.Kubonisa ukuba i-sepiolite ine-asidi eqinile kunye nokuchasana kwe-alkali, isizathu esibalulekileyo sokuba i-sepiolite isetyenziswe njenge-inorganic core ukulungiselela iMaya njenge-pigment eluhlaza okwesibhakabhaka.

(4) Iipropati ze-Catalytic ze-sepiolite

I-Sepiolite yinto enexabiso eliphantsi kwaye iyasebenza.Isizathu esona sizathu kukuba i-sepiolite inokufumana indawo ephezulu ephezulu kunye nesakhiwo sayo se-porous emva kokuguqulwa kwe-asidi, eziziimeko ezifanelekileyo zokusetyenziswa kwe-sepiolite njenge-catalyst carrier.I-Sepiolite ingasetyenziselwa njenge-carrier ukwenza i-photocatalyst kunye nokusebenza kakuhle kwe-catalytic kunye ne-TiO2, esetyenziswa ngokubanzi kwi-hydrogenation, i-oxidation, i-denitrification, i-desulfurization, njl.

(5) Ukutshintshwa kwe-ion ye-sepiolite

Indlela yokutshintshiselana nge-ion isebenzisa ezinye ii-cations zetsimbi nge-polarization eyomeleleyo ukuze ithathe indawo ye-Mg2 + ekupheleni kwe-octahedron kwisakhiwo se-sepiolite, ngaloo ndlela itshintsha isithuba somaleko kunye ne-asidi yomphezulu, kunye nokuphucula ukusebenza kwe-adsorption ye-sepiolite.I-ion zetsimbi ze-sepiolite zilawulwa yi-magnesium ion, kunye nenani elincinci le-aluminium ion kunye nenani elincinci lezinye ii-cations.Ukubunjwa okukhethekileyo kunye nesakhiwo se-sepiolite kwenza kube lula kwii-cations kwisakhiwo sayo ukutshintshiselana nezinye ii-cations.

(6) Iimpawu ze-Rheological ze-sepiolite

I-Sepiolite ngokwayo iyimilo yentonga ebhityileyo, kodwa uninzi lwazo ludityaniswe kwiingxowa ezinocwangco.Xa i-sepiolite ichithwa emanzini okanye kwezinye i-solvents ze-polar, ezi zibopho ziza kusasaza ngokukhawuleza kwaye zidibanise ngokungahambi kakuhle ukwenza inethiwekhi yefiber eyinkimbinkimbi kunye nokugcinwa kwe-solvent engavumelekanga.Ezi fom zenethiwekhi zenza ukumiswa nge-rheology enamandla kunye ne-viscosity ephezulu, ebonisa iimpawu ezikhethekileyo ze-rheological ze-sepiolite.

Ukongeza, i-sepiolite nayo ineempawu zokugquma, i-decolorization, i-flame retardancy kunye nokwandiswa, enexabiso elikhulu lesicelo kwintsimi yoshishino.

2. Izicelo eziphambili zeSepioliteinkqubo yomgubo ngeSepioliteilitye lokusila

Ngophuhliso olukhawulezayo loqoqosho lwaseTshayina, imfuno yentengiso yezinto ezisingqongileyo-enobuhlobo, iyanda.I-Sepiolite luhlobo lwe-inorganic material kunye nozinzo oluhle ngenxa yesakhiwo sayo esikhethekileyo sekristale, esingangcolisi, sinobume bendalo kunye nexabiso eliphantsi.Emva kokucutshungulwa ngumatshini wokugaya i-sepiolite, inokusetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zoshishino, ezifana ne-architecture, iteknoloji ye-ceramic, ukulungiswa kwe-catalyst, i-pigment synthesis, ukucocwa kwepetroleum, ukukhuselwa kwendalo, iiplastiki, njl., ezinempembelelo enkulu kwimizi-mveliso yaseChina. uphuhliso.Ngelo xesha, abantu baye baqala ukubeka ingqalelo ngakumbi kwi-innovative application kunye nophuhliso lwetekhnoloji ye-sepiolite, kunye nokukhawulezisa ukwakhiwa kwe-sepiolite industry chain chain ukusombulula ukunqongophala kwangoku kwe-sepiolite kwimarike Ixabiso eliphantsi elongezelelweyo leemveliso.
