Sepiolite wani nau'in ma'adinai ne mai siffar zare, wanda tsarin zare ne wanda ke fitowa daga bangon pore na polyhedral da kuma hanyar pore. Tsarin zaren ya ƙunshi tsari mai layi, wanda ya ƙunshi layuka biyu na Si-O-Si bond connected silicon oxide tetrahedron da octahedron wanda ke ɗauke da magnesium oxide a tsakiya, wanda ke samar da pore na zuma mai girman 0.36 nm × 1.06nm. Aikace-aikacen masana'antu na Sepiolite yawanci yana buƙatarniƙa niƙa na sepiolite foda da za a niƙa shi ya zama foda na sepiolite. HCMalling (Guilin Hongcheng) ƙwararren mai kera shi ne niƙa niƙa na sepioliteDuk kayan aikinmu niƙa niƙa na sepiolite An yi amfani da layin samarwa sosai a kasuwa. Barka da zuwa ƙarin koyo akan layi. Ga gabatarwar amfani da foda na sepiolite:

1. Halayen sepiolite

(1) Sifofin shaye-shaye na sepiolite

Sepiolite wani tsari ne na musamman mai girma uku wanda ke da babban yanki na musamman da kuma ramuka masu layi, wanda SiO2 tetrahedron da Mg-O octahedron ke dasawa. Akwai kuma cibiyoyin acidic [SiO4] alkaline [MgO6] da yawa a saman sa, don haka sepiolite yana da ƙarfin aikin sha.

Tsarin lu'ulu'u na Sepiolite yana da wurare uku daban-daban na tsakiyar shaye-shaye:

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

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

Na uku shine haɗin haɗin Si OH, wanda ake samarwa ta hanyar karyewar haɗin silicon oxygen a cikin tetrahedron SiO2 kuma yana karɓar ƙwayar proton ko hydrocarbon don rama ƙarfin da ya ɓace. Haɗin Si OH a cikin sepiolite na iya hulɗa da ƙwayoyin da ke shaƙa a saman sa don ƙarfafa shaƙa, kuma yana iya samar da haɗin haɗin gwiwa tare da wasu abubuwa na halitta.

(2) Daidaiton zafi na sepiolite

Sepiolite wani abu ne na yumbu mara tsari wanda ke da juriya ga zafin jiki mai ƙarfi. A lokacin dumama a hankali daga ƙarancin zafi zuwa babban zafin jiki, tsarin lu'ulu'u na sepiolite ya shiga matakai huɗu na rage nauyi:

Lokacin da zafin jiki na waje ya kai kimanin 100 ℃, ƙwayoyin ruwa da sepiolite za su rasa a mataki na farko sune ruwan zeolite a cikin ramuka, kuma asarar wannan ɓangaren ƙwayoyin ruwa ya kai kusan kashi 11% na jimlar nauyin sepiolite.

Lokacin da zafin jiki na waje ya kai 130 ℃ zuwa 300 ℃, sepiolite a mataki na biyu zai rasa kashi na farko na ruwan daidaitawa tare da Mg2+, wanda shine kusan 3% na nauyinsa.

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

Idan zafin jiki na waje ya kai sama da 500 ℃, ruwan tsarin (- OH) tare da octahedron a ciki zai ɓace a mataki na huɗu. Tsarin zare na sepiolite a wannan matakin ya lalace gaba ɗaya, don haka tsarin ba zai iya canzawa ba.

(3) Juriyar tsatsa ta sepiolite

Sepiolite ta halitta tana da kyakkyawan juriya ga acid da alkali. Idan tana cikin matsakaici tare da ƙimar pH <3 ko>10, tsarin ciki na sepiolite zai lalace. Lokacin da yake tsakanin 3-10, sepiolite yana nuna ƙarfi da kwanciyar hankali. Yana nuna cewa sepiolite yana da ƙarfi da juriya ga acid da alkali, wanda shine muhimmin dalili da yasa ake amfani da sepiolite azaman tushen da ba shi da tsari don shirya launin shuɗi mai kama da Maya.

(4) Halayen abubuwan da ke haifar da tasirin sepiolite

Sepiolite mai ɗaukar sinadarin catalyst ne mai araha kuma mai amfani. Babban dalili shine cewa sepiolite na iya samun mafi girman yanki na saman da kuma tsarinsa mai lanƙwasa bayan an gyara acid, wanda shine yanayi mai kyau don amfani da sepiolite azaman mai ɗaukar sinadarin catalyst. Ana iya amfani da Sepiolite azaman mai ɗaukar sinadarin don samar da mai ɗaukar sinadarin photocatalyst tare da kyakkyawan aikin catalytic tare da TiO2, wanda ake amfani dashi sosai a cikin hydrogenation, oxidation, denitrification, desulfurization, da sauransu.

(5) Musayar ion na sepiolite

Hanyar musayar ion tana amfani da wasu cations na ƙarfe masu ƙarfi don maye gurbin Mg2+ a ƙarshen octahedron a cikin tsarin sepiolite, don haka canza tazara tsakanin layukan da acidity na saman, da haɓaka aikin sha na sepiolite. ions na ƙarfe na sepiolite suna mamaye da ions na magnesium, tare da ƙaramin adadin ions na aluminum da ƙaramin adadin wasu cations. Tsarin musamman da tsarin sepiolite yana sa cations a cikin tsarinsa su yi musayar su da sauran cations.

(6) Halayen ilimin halittar sepiolite

Sepiolite kanta siririyar siffa ce ta sanda, amma yawancinsu an tara su cikin tarin abubuwa ba tare da tsari ba. Lokacin da sepiolite ya narke a cikin ruwa ko wasu sinadarai masu narkewa a cikin polar, waɗannan tarin za su watse cikin sauri su haɗu cikin rashin tsari don samar da hanyar sadarwa ta fiber mai rikitarwa tare da riƙewar sinadarai marasa tsari. Waɗannan hanyoyin sadarwa suna samar da dakatarwa mai ƙarfi da kuma ɗanko mai yawa, wanda ke nuna halayen rheological na musamman na sepiolite.

Bugu da ƙari, sepiolite yana da halaye na rufi, canza launi, jinkirin harshen wuta da faɗaɗawa, wanda ke da babban ƙimar aikace-aikace a fagen masana'antu.

2. Babban Amfani da Sepiolitetsarin foda ta hanyarSepioliteniƙa niƙa

Tare da saurin ci gaban tattalin arzikin kasar Sin, bukatar kasuwa ta kayayyakin da suka dace da muhalli, masu daraja na karuwa. Sepiolite wani nau'in kayan da ba na halitta ba ne, wanda ke da kyakkyawan kwanciyar hankali saboda tsarin kristal na musamman, wanda ba shi da gurɓatawa, mai sauƙin muhalli kuma mai arha. Bayan an sarrafa shi ta hanyar injin niƙa na sepiolite, ana iya amfani da shi sosai a fannoni daban-daban na masana'antu, kamar gine-gine, fasahar yumbu, shirye-shiryen kara kuzari, hada launuka, tace mai, kariyar muhalli, robobi, da sauransu, wanda ke da babban tasiri ga ci gaban masana'antar kasar Sin. A lokaci guda, mutane sun fara mai da hankali kan sabbin aikace-aikace da ci gaban fasaha na sepiolite, da kuma hanzarta gina sarkar masana'antar sepiolite mai inganci don magance karancin sepiolite a kasuwa.
