Ulusi wopangidwa makamaka ndi mchere wa sepiolite umatchedwa sepiolite mineral fibers.sepiolite ndi mchere wochuluka wa magnesium silicate fiber wokhala ndi physicochemical formula ya Mgo [Si12O30] (OH) 4 12 H2O.Mamolekyu anayi amadzi ndi madzi a crystalline, ena onse ndi madzi a zeolite, ndipo nthawi zambiri amakhala ndi zinthu zochepa monga manganese ndi chromium.

Sepiolite imakhala ndi ma adsorption abwino, decolorization, kukhazikika kwamafuta, kukana kwa dzimbiri, kukana kwa radiation, kutchinjiriza kwamafuta, kukana kukangana, komanso kukana kulowa, ndipo imagwiritsidwa ntchito kwambiri pobowola, mafuta, mankhwala, kufungira, zomangira, mankhwala ophera tizilombo, feteleza, zinthu za mphira, braking. , ndi magawo ena.

Zofunikira za ulusi wamchere wa sepiolite m'magawo ena ndi izi:

The decolorization rate ndi ≥ 100%, pulping rate ndi> 4m3 / t, ndipo dispersibility ndi mofulumira, katatu kuposa asbestosi.Malo osungunuka ndi 1650 ℃, mamasukidwe akayendedwe ndi 30-40s, ndipo amatha kuwola mwachilengedwe osatulutsa kuipitsa.Ndi mfundo yachiwiri ya ndondomeko yaulere ya asibesitosi yomwe yakhala ikugwiritsidwa ntchito kunja ndipo imadziwika kuti green mineral fiber.

mwayi

1. Kugwiritsira ntchito sepiolite ngati mankhwala a rabala ndi opanda zowononga, ndi ntchito yabwino yosindikiza komanso kukana kwa asidi wambiri.

2. Kuwotcha ndi sepiolite kumapangitsa kuti madzi asungunuke kasanu ndi kawiri ndi kuyeretsa kuposa asibesitosi.

3. Kugwiritsa ntchito sepiolite pa kukangana kumakhala ndi kusungunuka kwabwino, kulimba kokhazikika, komanso kutsekemera kwa mawu 150 kuchulukitsa kwa asibesitosi.Phokoso la mkangano ndilotsika kwambiri, ndipo ndi chinthu chowonjezera chamtengo wapatali chopangira ndalama zogulitsa kunja.

Sepiolite fiber ndi mchere wachilengedwe, womwe ndi wosiyanasiyana wa mchere wa sepiolite ndipo umatchedwa α-Sepiolite.Malinga ndi akatswiri, sepiolite, monga layered unyolo silicate mchere, ali 2:1 layered structural unit wopangidwa ndi zigawo ziwiri za silikoni oxygen tetrahedra sandwich wosanjikiza wa magnesium oxygen octahedra.Gawo la tetrahedral limapitilira, ndipo mawonekedwe amtundu wa okosijeni wokhazikika pagawolo amasinthidwa nthawi ndi nthawi.Zigawo za octahedral zimapanga ngalande zokonzedwa mosinthana pakati pa zigawo zakumwamba ndi zapansi.Mayendedwe a njirayo amagwirizana ndi fiber axis, kulola kuti mamolekyu amadzi, ma cations achitsulo, mamolekyu ang'onoang'ono achilengedwe alowemo.Sepiolite ili ndi kukana kutentha kwabwino, kusinthanitsa kwa ion ndi zida zothandizira, komanso zinthu zabwino kwambiri monga kukana dzimbiri, kukana kwa radiation, kutsekereza, komanso kutsekemera kwamafuta.Makamaka, Si-OH m'mapangidwe ake amatha kuchitapo kanthu mwachindunji ndi zinthu zakuthupi kuti apange organic mineral zotumphukira.

M'magawo ake, silicon oxide tetrahedra ndi magnesium oxide octahedra amasinthana wina ndi mzake, kuwonetsa mawonekedwe a kusintha kwa zosanjikiza ndi unyolo wonga maunyolo.Sepiolite ili ndi mawonekedwe apadera a thupi ndi mankhwala, okhala ndi malo apamwamba kwambiri (mpaka 800-900m / g), porosity yaikulu, ndi mphamvu zokopa komanso zochititsa chidwi.

Minda yogwiritsira ntchito sepiolite ndi yochuluka kwambiri, ndipo pambuyo pa mankhwala angapo monga kuyeretsedwa, kukonza bwino kwambiri, ndi kusinthidwa, sepiolite ingagwiritsidwe ntchito ngati adsorbent, kuyeretsa wothandizira, deodorant, kulimbikitsa wothandizira, kuyimitsidwa, wothandizira thixotropic, kudzaza wothandizila, etc. m'zinthu zamafakitale monga kuthira madzi, catalysis, mphira, zokutira, feteleza, chakudya, ndi zina zotero. Kuphatikiza apo, kukana kwa mchere wabwino komanso kutentha kwa kutentha kwa sepiolite kumapangitsa kuti pakhale matope apamwamba kwambiri omwe amagwiritsidwa ntchito mu petroleum. kubowola, kubowola kwa geothermal, ndi madera ena.
