1. Properties na sepiolite

(1) Adsorption Properties na sepiolite

Sepiolite wani tsari ne na musamman mai girma uku tare da ƙayyadaddun yanki na musamman da kuma porosity mai laushi, wanda SiO2 tetrahedron da Mg-O octahedron suka yi.Hakanan akwai cibiyoyi masu yawa na acidic [SiO4] alkaline [MgO6] akan saman sa, don haka sepiolite yana da ƙarfin tallan talla.

Tsarin kristal na Sepiolite yana da wurare daban-daban na adsorption masu aiki:

Na farko shine O atom a cikin Si-O tetrahedron;

Na biyu shine kwayoyin ruwa wadanda ke daidaitawa da Mg2+ a gefen Mg-O octahedron, galibi suna samar da haɗin gwiwar hydrogen tare da wasu abubuwa;

Na uku shine haɗin haɗin Si OH, wanda aka samo shi ta hanyar karyewar haɗin oxygen na silicon a cikin SiO2 tetrahedron kuma yana karɓar proton ko kwayoyin hydrocarbon don rama abin da ya ɓace.Haɗin Si OH a cikin sepiolite zai iya yin hulɗa tare da kwayoyin da aka tallata a samansa don ƙarfafa adsorption, kuma zai iya samar da haɗin gwiwa tare da wasu abubuwa na halitta.

(2) Thermal kwanciyar hankali na sepiolite

Sepiolite wani abu ne na yumbu mai inorganic tare da tsayin daka mai tsayin zafi.A lokacin tsarin dumama a hankali daga ƙananan zafin jiki zuwa babban zafin jiki, tsarin crystal na sepiolite ya wuce matakan asarar nauyi guda huɗu:

Lokacin da zafin jiki na waje ya kai kimanin 100 ℃, kwayoyin ruwa da sepiolite zasu rasa a mataki na farko shine ruwan zeolite a cikin pores, kuma asarar wannan bangare na kwayoyin ruwa ya kai kimanin 11% na nauyin nauyin sepiolite.

Lokacin da zafin jiki na waje ya kai 130 ℃ zuwa 300 ℃, sepiolite a mataki na biyu zai rasa kashi na farko na ruwa tare da Mg2 +, wanda shine game da 3% na yawan sa.

Lokacin da zafin jiki na waje ya kai 300 ℃ zuwa 500 ℃, sepiolite a mataki na uku zai rasa kashi na biyu na ruwa mai daidaitawa tare da Mg2+.

Lokacin da zafin jiki na waje ya kai sama da 500 ℃, ruwan tsarin (-OH) hade da octahedron a ciki zai rasa a mataki na hudu.Tsarin fiber na sepiolite a cikin wannan matakin ya lalace gaba ɗaya, don haka tsarin ba zai yuwu ba.

(3) Juriya na lalata na sepiolite

Sepiolite a dabi'a yana da kyakkyawan juriya na acid da alkali.Lokacin da yake a cikin matsakaici tare da bayani pH darajar <3 ko>10, tsarin ciki na sepiolite zai lalace.Lokacin da yake tsakanin 3-10, sepiolite yana nuna kwanciyar hankali mai ƙarfi.Ya nuna cewa sepiolite yana da ƙarfin acid da juriya na alkali, wanda shine muhimmin dalilin da yasa ake amfani da sepiolite azaman inorganic core don shirya Maya kamar blue pigment.

(4) Kaddarorin kaddarorin na sepiolite

Sepiolite mai arha ne kuma mai ɗaukar nauyi mai amfani.Babban dalili shi ne cewa sepiolite na iya samun wani yanki na musamman na musamman da kuma tsarinsa mai laushi mai laushi bayan gyaran acid, wanda shine kyawawan yanayi don amfani da sepiolite a matsayin mai ɗaukar hoto.Ana iya amfani da Sepiolite azaman mai ɗaukar hoto don samar da photocatalyst tare da kyakkyawan aikin haɓakawa tare da TiO2, wanda aka yi amfani da shi sosai a cikin hydrogenation, oxidation, denitrification, desulfurization, da sauransu.

(5) ion musayar sepiolite

Hanyar musayar ion tana amfani da wasu cations na ƙarfe tare da polarization mai ƙarfi don maye gurbin Mg2+ a ƙarshen octahedron a cikin tsarin sepiolite, don haka canza tazarar Layer da acidity na saman, da haɓaka aikin adsorption na sepiolite.Abubuwan ions na ƙarfe na sepiolite sun mamaye ions na magnesium, tare da ƙananan ions na aluminum da ƙananan adadin sauran cations.Abun da ke ciki na musamman da tsarin sepiolite yana sauƙaƙe cations a cikin tsarinsa don musanya tare da sauran cations.

(6) Rheological Properties na sepiolite

Sepiolite kanta siffar sanda ce siriri, amma yawancinsu ana tara su cikin daure tare da tsari mara tsari.Lokacin da aka narkar da sepiolite a cikin ruwa ko wasu abubuwan kaushi na polar, waɗannan dam ɗin za su watse da sauri kuma su haɗa cikin ɓarna don samar da hadadden hanyar sadarwa na fiber tare da riƙewar ƙarfi mara daidaituwa.Wadannan hanyoyin sadarwa suna samar da dakatarwa tare da rheology mai karfi da kuma danko mai girma, yana nuna nau'in rheological na musamman na sepiolite.

Bugu da kari, sepiolite kuma yana da halaye na rufi, decolorization, harshen wuta retardancy da expansibility, wanda yana da babban aikace-aikace darajar a masana'antu filin.
