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

Sepiolite ili ndi mayamwidwe abwino, kusintha mtundu, kukhazikika kwa kutentha, kukana dzimbiri, kukana kuwala kwa dzuwa, kutchinjiriza kutentha, kukana kukangana, komanso kukana kulowa mkati, ndipo imagwiritsidwa ntchito kwambiri pakubowola, mafuta, mankhwala, kupanga mowa, zipangizo zomangira, mankhwala ophera tizilombo, feteleza, zinthu za rabara, mabuleki, ndi zina.

Zofunikira pa ulusi wa mchere wa sepiolite m'magawo ena ndi izi:

Kuchuluka kwa utoto ndi ≥ 100%, kuchuluka kwa pulping ndi>4m3/t, ndipo kufalikira kwake ndi kwachangu, katatu kuposa asbestos. Malo osungunuka ndi 1650 ℃, kukhuthala kwake ndi 30-40s, ndipo amatha kuwola mwachilengedwe popanda kuipitsa. Ndi gawo lachiwiri la dongosolo lopanda asbestos lomwe likulimbikitsidwa kwambiri mdziko lonse, lomwe lagwiritsidwa ntchito kwathunthu kunja ndipo limadziwika kuti ulusi wobiriwira wa mchere.

ubwino

1. Kugwiritsa ntchito sepiolite ngati chinthu cha rabara sikuipitsa, kumakhala ndi magwiridwe antchito abwino kwambiri otsekera komanso kukana asidi kwambiri.

2. Kuphika ndi sepiolite kumapangitsa kuti madzi asinthe mtundu ndi kuyeretsa kuwirikiza kasanu ndi kawiri kuposa asbestos.

3. Kugwiritsa ntchito sepiolite pakukangana kumakhala ndi kusinthasintha kwabwino, kuuma kokhazikika, komanso kutengera phokoso nthawi 150 kuposa asbestos. Phokoso la kukangana ndi lochepa kwambiri, ndipo ndi zinthu zopangira zomwe zimawonjezera phindu lotumizira kunja.

Ulusi wa Sepiolite ndi ulusi wachilengedwe wa mchere, womwe ndi mtundu wa ulusi wa mchere wa sepiolite ndipo umatchedwa α-Sepiolite. Malinga ndi akatswiri, sepiolite, monga mchere wa silicate wopangidwa ndi zigawo ziwiri, ili ndi gawo la 2:1 lopangidwa ndi zigawo ziwiri za silicon oxygen tetrahedra yokhala ndi wosanjikiza wa magnesium oxygen octahedra. Gawo la tetrahedral limakhala lopitirira, ndipo mawonekedwe a mitundu ya okosijeni yogwira ntchito mu wosanjikizawo amasinthidwa nthawi ndi nthawi. Zigawo za octahedral zimapanga njira zokhazikika pakati pa zigawo zapamwamba ndi zapansi. Mawonekedwe a njirayo amagwirizana ndi mzere wa ulusi, zomwe zimathandiza mamolekyulu amadzi, zitsulo, mamolekyulu ang'onoang'ono achilengedwe, ndi zina zotero kuti alowemo. Sepiolite ili ndi kukana kutentha bwino, kusinthana kwa ma ion ndi zinthu zoyambitsa, komanso makhalidwe abwino kwambiri monga kukana dzimbiri, kukana ma radiation, kutchinjiriza, ndi kutchinjiriza kutentha. Makamaka, Si-OH m'mapangidwe ake imatha kuchita mwachindunji ndi zinthu zachilengedwe kuti ipange zinthu zochokera ku mchere wachilengedwe.

Mu kapangidwe kake, silicon oxide tetrahedra ndi magnesium oxide octahedra zimasinthasinthana, kusonyeza makhalidwe osinthika a kapangidwe kokhala ndi zigawo ndi unyolo. Sepiolite ili ndi mphamvu zapadera zakuthupi ndi zamakemikolo, yokhala ndi malo apamwamba kwambiri (mpaka 800-900m/g), ma porosity akuluakulu, komanso mphamvu zamphamvu zoyatsira ndi kusonkhezera.

Magawo ogwiritsira ntchito sepiolite nawonso ndi ochulukirapo, ndipo pambuyo pa njira zingapo monga kuyeretsa, kukonza bwino kwambiri, ndi kusintha, sepiolite ingagwiritsidwe ntchito ngati chokometsera, choyeretsera, chochotsera fungo loipa, cholimbitsa, choyimitsa, chothandizira thixotropic, chodzaza, ndi zina zotero m'mafakitale monga kuyeretsa madzi, catalysis, rabara, zokutira, feteleza, chakudya, ndi zina zotero. Kuphatikiza apo, kukana mchere wabwino komanso kukana kutentha kwambiri kwa sepiolite kumapangitsa kuti ikhale chinthu chapamwamba kwambiri chobowola chomwe chimagwiritsidwa ntchito pobowola mafuta, kubowola kwa geothermal, ndi zina.
