Sepiolite imhando yemineral ine chimiro chefiber, inova chimiro chefiber chinotambanuka kubva pamadziro epore nepaburi repore. Chimiro chefiber chine chimiro chakaiswa, icho chine zvikamu zviviri zveSi-O-Si bond yakabatana nesilicon oxide tetrahedron neoctahedron ine magnesium oxide pakati, ichigadzira 0.36 nm × 1.06nm honeycomb pore. Kushandiswa kweSepiolite mumaindasitiri kunowanzo dachigayo chekukuya che sepiolite upfu hunogayiwa kuita upfu hwe sepiolite. HCMilling (Guilin Hongcheng) inyanzvi yekugadzira chigayo chekukuya che sepioliteSeti yese yemidziyo yedu chigayo chekukuya che sepiolite Mutsetse wekugadzira wave uchishandiswa zvakanyanya pamusika. Tinokugamuchirai kuti mudzidze zvakawanda online. Zvinotevera ndizvo zvinotanga kushandiswa kwehupfu hwesepiolite:

1. Hunhu hwe sepiolite

(1) Hunhu hwekunyungudutsa kwesepiolite

Sepiolite imhando yemhando nhatu ine nzvimbo yakakura uye porosity yakatsetseka, iyo inosunganidzwa neSiO2 tetrahedron uye Mg-O octahedron. Kunewo nzvimbo dzakawanda dzine acidic [SiO4] alkaline [MgO6] pamusoro payo, saka sepiolite ine simba rakasimba rekunyungudutsa mvura.

Chimiro chekristaro cheSepiolite chine nzvimbo nhatu dzakasiyana dze adsorption active centre:

Chekutanga iatomu reO muSi-O tetrahedron;

Chechipiri mamorekuru emvura anowirirana neMg2+ pamucheto weMg-O octahedron, achinyanya kugadzira zvisungo zvehydrogen nezvimwe zvinhu;

Chechitatu iboka reSi OH, iro rinogadzirwa nekutyoka kweboka resilicon oxygen muSiO2 tetrahedron uye rinowana proton kana hydrocarbon molecule kuti ritsive simba risipo. Bond reSi OH mu sepiolite rinogona kusangana nemamorekuru akanyudzwa pamusoro paro kusimbisa adsorption, uye rinogona kuumba ma covalent bonds nezvimwe zvinhu zvipenyu.

(2) Kugadzikana kwekupisa kwe sepiolite

Sepiolite ivhu remhando ye inorganic rine simba rakasimba rekudzivirira kupisa kwakanyanya. Munguva yekupisa zvishoma nezvishoma kubva pakupisa kwakaderera kusvika pakupisa kwakakwirira, chimiro chekristaro che sepiolite chakapfuura nematanho mana ekuderedza uremu:

Kana tembiricha yekunze yasvika pa100 ℃, mamorekuru emvura ayo sepiolite icharasikirwa nawo padanho rekutanga imvura yezeolite iri mumaburi, uye kurasikirwa kwechikamu ichi chemamorekuru emvura kunosvika pa11% yehuremu hwese hwese hwesepiolite.

Kana tembiricha yekunze yasvika 130 ℃ kusvika 300 ℃, sepiolite muchikamu chechipiri icharasikirwa nechikamu chekutanga chemvura inobatanidza neMg2+, inova inenge 3% yehuremu hwayo.

Kana tembiricha yekunze yasvika 300 ℃ kusvika 500 ℃, sepiolite muchikamu chechitatu icharasikirwa nechikamu chechipiri chemvura inobatanidza neMg2+.

Kana tembiricha yekunze yasvika pamusoro pe500 ℃, mvura yemuumbi (- OH) yakasanganiswa neoctahedron iri mukati icharasika padanho rechina. Maumbirwo efiber e sepiolite padanho rino akaparadzwa zvachose, saka maitiro acho haadzoreki.

(3) Kuramba ngura kwe sepiolite

Sepiolite ine simba rakanaka rekudzivirira acid nealkali. Kana iri pakati pemvura ine pH <3 kana>10, chimiro chemukati chesepiolite chinoora. Kana iri pakati pe3-10, sepiolite inoratidza kugadzikana kwakasimba. Izvi zvinoratidza kuti sepiolite ine simba rekudzivirira acid nealkali, ndicho chikonzero chakakosha nei sepiolite ichishandiswa senzvimbo isina kugadzirwa kugadzira Maya yakaita seruvara rwebhuruu.

(4) Hunhu hweSepiolite hweCatalytic

Sepiolite inotakura zvinhu zvinokonzeresa mvura zvakachipa uye zvinoshanda. Chikonzero chikuru ndechekuti sepiolite inogona kuwana nzvimbo yepamusoro uye chimiro chayo chine maburi mushure mekugadzirisa acid, izvo zviri mamiriro akanaka ekushandiswa kwesepiolite semutakura zvinhu zvinokonzeresa mvura. Sepiolite inogona kushandiswa semutakura kugadzira photocatalyst ine simba rakanaka rekugadzira zvinhu zvinokonzeresa mvura neTiO2, iyo inoshandiswa zvakanyanya muhydrogenation, oxidation, denitrification, desulfurization, nezvimwewo.

(5) Kuchinjana kwemaion e sepiolite

Nzira yekuchinjana maion inoshandisa mamwe ma cation esimbi ane polarization yakasimba kutsiva Mg2+ pakupera kwe octahedron muchimiro che sepiolite, nokudaro ichichinja nzvimbo yayo ye layer uye surface acidity, uye ichivandudza adsorption performance ye sepiolite. Ma ions esimbi e sepiolite anotongwa nema magnesium ions, ane ma ions mashoma e aluminium uye ma cations mashoma. Kuumbwa kwakakosha uye chimiro che sepiolite kunoita kuti zvive nyore kuti ma cations ari muchimiro chayo achinje nemamwe ma cations.

(6) Hunhu hwe sepiolite mu rheological

Sepiolite pachayo ine chimiro chetsvimbo diki, asi zhinji dzacho dzakaunganidzwa kuita mabundles asina kurongeka zvakanaka. Kana sepiolite ikanyungudutswa mumvura kana mune zvimwe zvinonyungudutsa, mabundles aya anokurumidza kupararira uye kusangana zvisina kurongeka kuti agadzire network yakaoma yefiber ine solvent retention isina kurongeka zvakanaka. Mafomu aya enetwork anoita suspension ine rheology yakasimba uye viscosity yakakwira, ichiratidza hunhu hwakasiyana hwe rheological hwesepiolite.

Pamusoro pezvo, sepiolite ine hunhu hwekuputira, kubvisa ruvara, kunonoka kwemurazvo uye kuwedzera, izvo zvine kukosha kukuru muindasitiri.

2. Mashandisirwo Akanyanya eSepiolitemaitiro eupfu neSepiolitechigayo chekukuya

Nekukura kuri kuita hupfumi hweChina nekukurumidza, kudiwa kwezvinhu zvisingakuvadzi nharaunda uye zvine kukosha kwakanyanya kuri kuwedzera pamusika. Sepiolite imhando yezvinhu zvisingararami zvine kugadzikana kwakanaka nekuda kwechimiro chayo chekristaro, chisina kusvibiswa, chisingakuvadzi nharaunda uye chakachipa. Mushure mekunge yagadziriswa nemuchina wekukuya wesepiolite, inogona kushandiswa zvakanyanya muminda yakasiyana-siyana yemaindasitiri, senge kuvaka, tekinoroji yeceramic, kugadzirira catalyst, kugadzira pigment, kucheneswa kwepetroleum, kuchengetedzwa kwenharaunda, mapurasitiki, nezvimwewo, izvo zvine simba guru pakukura kwemaindasitiri eChina. Panguva imwe chete, vanhu vatanga kutarisisa zvakanyanya kushandiswa kwehunyanzvi uye kuvandudzwa kwetekinoroji yesepiolite, uye kukurumidzisa kuvakwa kweketani yeindasitiri yesepiolite yakaoma kugadzirisa kushomeka kwesepiolite pari zvino mumusika. Kukosha kwakaderera kwezvinhu.
