Sepiolite imhando yemaminerari ane faibha fomu, inova chimiro chefiber chinotambanuka chichichinjika kubva pa polyhedral pore madziro uye pore chiteshi.Iyo fiber chimiro ine layered chimiro, iyo inoumbwa nezvikamu zviviri zveSi-O-Si bond yakabatana nesilicon oxide tetrahedron uye octahedron ine magnesium oxide pakati, ichigadzira 0.36 nm × 1.06nm huchi pore.Sepiolite indasitiri application inowanzodasepiolite ichikuya chigayo hupfu hwekukuyiwa kuita sepiolite upfu.HCMilling(Guilin Hongcheng) inyanzvi inogadzira sepiolite ichikuya chigayo.Iyo yese seti yemidziyo yedu sepiolite ichikuya chigayo mutsara wekugadzira wakashandiswa zvakanyanya mumusika.Kugamuchirwa kuti udzidze zvakawanda online.Izvi zvinotevera sumo yekushandiswa kwesepiolite powder:

 

1. Zvinhu zve sepiolite

(1) Adsorption zvimiro zve sepiolite

Sepiolite itatu-dimensional yakakosha chimiro ine yakakura chaiyo nzvimbo uye akaturikidzana porosity, iyo inobatanidzwa neSiO2 tetrahedron uye Mg-O octahedron.Kune zvakare akawanda acidic [SiO4] alkaline [MgO6] nzvimbo pamusoro payo, saka sepiolite ine yakasimba adsorption performance.

 

Sepiolite crystal chimiro chine matatu akasiyana adsorption anoshanda nzvimbo nzvimbo:

Yokutanga iO atomu muSi-O tetrahedron;

Chechipiri mamorekuru emvura anowirirana neMg2+ kumucheto kweMg-O octahedron, kunyanya achigadzira mahydrogen bond nezvimwe zvinhu;

 

Yetatu ndeyeSi OH bond musanganiswa, iyo inogadzirwa nekutyoka kwesilicon oxygen bond muSiO2 tetrahedron uye inogamuchira proton kana hydrocarbon molecule kutsiva iyo inoshaikwa.Iyo Si OH bond mu sepiolite inogona kudyidzana nemamorekuru adsorbed pamusoro payo kusimbisa adsorption, uye inogona kugadzira covalent zvisungo nezvimwe organic zvinhu.

 

(2) Thermal kugadzikana kwe sepiolite

Sepiolite ndeye inorganic ivhu zvinhu ine yakagadzikana yakakwirira tembiricha kuramba.Munguva yekudziya zvishoma nezvishoma kubva pakudziya kwakadzika kusvika kune yakanyanya tembiricha, chimiro chekristaro che sepiolite chapfuura nematanho mana ekurasikirwa nehuremu:

 

Kana tembiricha yekunze yasvika pa100 ℃, mamorekuru emvura anorasikirwa nesepiolite padanho rekutanga imvura yezeolite mumapores, uye kurasikirwa kwechikamu ichi chemamorekuru emvura kunosvika 11% yehuremu hwesepiolite.

 

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

 

Kana tembiricha yekunze yasvika 300 ℃ kusvika 500 ℃, sepiolite muchikamu chechitatu inorasikirwa nechikamu chechipiri chekubatanidza mvura neMg2 +.

 

Kana tembiricha yekunze yasvika pamusoro pe500 ℃, mvura yezvimiro (- OH) yakasanganiswa neoctahedron mukati inorasika muchikamu chechina.Iyo fiber chimiro che sepiolite mune ino nhanho yakaparadzwa zvachose, saka maitiro haachinjike.

 

(3) Corrosion resistance ye sepiolite

Sepiolite zvakasikwa ine yakanaka asidhi uye alkali kuramba.Kana iri pakati nepakati nemhinduro pH kukosha <3 kana> 10, chimiro chemukati che sepiolite chichasvibiswa.Kana iri pakati pe3-10, sepiolite inoratidza kugadzikana kwakasimba.Zvinoratidza kuti sepiolite ine asidhi yakasimba uye alkali kuramba, icho chikonzero chakakosha nei sepiolite ichishandiswa se inorganic core kugadzirira Maya seblue pigment.

 

(4) Catalytic zvimiro zve sepiolite

Sepiolite inochipa uye inoshanda inotakura inotakura.Chikonzero chikuru ndechekuti sepiolite inogona kuwana yakakwira chaiyo nzvimbo uye yayo yakaturikidzana porous chimiro mushure mekugadziriswa kweasidhi, ayo ari mamiriro akanaka ekushandiswa kwesepiolite se catalyst carrier.Sepiolite inogona kushandiswa semutakuri kugadzira photocatalyst ine yakanakisa catalytic kuita neTiO2, iyo inoshandiswa zvakanyanya muhydrogenation, oxidation, denitrification, desulfurization, nezvimwe.

 

(5) Ion kuchinjana kwe sepiolite

Iyo ion yekutsinhana nzira inoshandisa mamwe simbi cations ane akasimba polarization kutsiva Mg2 + pakupera kweoctahedron mune sepiolite chimiro, nekudaro ichichinja nzvimbo yayo yakatsetseka uye acidity yepasi, uye kuwedzera adsorption kuita kwesepiolite.Ioni dzesimbi dze sepiolite dzinotungamirirwa ne magnesium ions, ine shoma shoma yearuminiyamu ion uye shoma shoma yemamwe cations.Iyo yakakosha kuumbwa uye chimiro che sepiolite chinoita kuti zvive nyore kune cations muchimiro chayo kuchinjana nemamwe cations.

 

(6) Rheological properties ye sepiolite

Sepiolite pachayo chimiro chakatetepa chetsvimbo, asi mazhinji acho anoturikidzwa mumasumbu asina kurongeka.Kana sepiolite yakanyungudutswa mumvura kana zvimwe zvinonyungudutsa polar, masumbu aya achakurumidza kupararira uye kupindirana zvisina kurongeka kuti aite yakaoma fiber network ine isingawanzo solvent retention.Aya mafomu etiweki anoumba kumiswa ane rheology yakasimba uye yakakwirira viscosity, inoratidza yakasarudzika rheological zvimiro zve sepiolite.

 

Uye zvakare, sepiolite zvakare ine hunhu hwekuisa, decolorization, kudzoreredza murazvo uye kuwedzera, iyo ine hukuru hwekushandisa kukosha mundima yeindasitiri.

 

2. Main Applications yeSepiolitehupfu process bySepiolitekugaya

Nekukurumidza kusimukira kwehupfumi hweChina, kudiwa kwemusika wezvakatipoteredza-hushamwari, zvinhu zvakawedzerwa zvakakosha zviri kukura.Sepiolite imhando yezvinhu zvisingaverengeki zvine kugadzikana kwakanaka nekuda kwechimiro chayo chekristaro, iyo isina kusvibiswa-isina, nharaunda-inoshamwaridzika uye yakachipa.Mushure mekugadzirwa ne sepiolite kugaya muchina, inogona kushandiswa zvakanyanya munzvimbo dzakasiyana siyana dzemaindasitiri, senge architecture, ceramic tekinoroji, catalyst kugadzirira, pigment synthesis, petroleum kunatsa, kuchengetedza kwezvakatipoteredza, mapurasitiki, nezvimwewo, izvo zvine simba guru kumaindasitiri eChina. development.Panguva imwecheteyo, vanhu vatanga kutarisisa kune innovative application uye tekinoroji kusimudzira sepiolite, uye nekukasira kuvakwa kweiyo sophisticated sepiolite indasitiri chain kugadzirisa kushomeka kwazvino kwesepiolite mumusika Kuderera kwakawedzera kukosha kwezvigadzirwa.
