Thandizo la sefa ya Diatomiteali ndi mawonekedwe abwino a microporous, adsorption performance ndi anti-compression performance, zomwe sizimangopangitsa kuti madzi osefedwa azitha kupeza bwino, komanso amasefa zolimba zolimba kuti ziwoneke bwino. Dziko la Diatomaceous ndilo gawo la zotsalira za diatoms zakale za cell imodzi. Makhalidwe ake: kulemera kopepuka, porous, mphamvu yayikulu, kukana kuvala, kutchinjiriza, kutsekereza kutentha, kutsatsa ndi kudzaza ndi zina zabwino kwambiri. Masiku ano, Julian diatomite adzatchuka several njira zosiyanasiyana zosefera za diatomite zosefera zothandizira.

Thandizo la zosefera la diatomite makamaka limatchera tinthu tating'onoting'ono tomwe timayimitsidwa pamadzi pamwamba pa sing'anga ndi njira kudzera muzochita zitatu zowunikira, kuyatsa, ndi kutsatsa, kuti mukwaniritse cholinga cha kulekanitsa kwamadzi olimba.

1. Diatomite screening effect: Izi ndizomwe zimasefa pamwamba. Madziwo akamadutsa m'dziko la diatomaceous, ma pores a dziko lapansi a diatomaceous amakhala ochepa kuposa kukula kwa tinthu tazonyansa, kotero kuti zonyansazo sizingadutse ndikulandidwa. Zotsatira zake zimatchedwa screening effect.

2. Kuzama kwa Diatomite: Kuzama kwakuya ndikusungirako kusefera kozama. Mu kusefa kwambiri, njira yolekanitsa imangochitika "mkati" mwa sing'anga. Mbali ya tinthu tating'ono tonyansa tomwe timalowa pamwamba pa keke ya fyuluta imakutidwa ndi diatomite. The mkati tortuous microporous dongosolo ndi bwino pores mkati fyuluta keke oletsedwa. Tinthu tating'onoting'ono tomwe timakhala tating'onoting'ono kuposa ma micropores a dziko lapansi la diatomaceous. Pamene particles kugunda khoma la njira, iwo akhoza kusiya madzi otaya. Komabe, ngati zingatheke izi zimadalira mphamvu ya inertial mphamvu ndi kukana kwa tinthu tating'onoting'ono. Kuyikira uku ndi kuwunika ndizofanana m'chilengedwe, ndipo zonse zimakhala ndi zotsatira zamakina. Kutha kusefa tinthu tating'onoting'ono timangogwirizana ndi kukula kwake ndi mawonekedwe a tinthu tolimba ndi pores.

3. Diatomite adsorption: The adsorption kwenikweni akhoza kuonedwa ngati electrokinetic kukopa, zomwe makamaka zimadalira pamwamba katundu wa particles olimba ndi diatomite palokha. Pamalo a dziko lapansi la diatomaceous ndilabwino, mtengo wake ndi waukulu, ndipo imatha kutsatsa bwino ndalama zolipiritsa. Pamene tinthu ting'onoting'ono kuposa ma pores amkati a dziko lapansi la diatomaceous atawombana pamtunda wa porous diatomaceous lapansi, amakopeka ndi magetsi. Palinso mtundu wa kukopana pakati pa tinthu tating'onoting'ono kuti tipange masango ndikumamatira ku dziko la diatomaceous. Zonsezi ndi za adsorption, ndipo kutsatsa kumakhala kovuta kwambiri kuposa zotsatira ziwiri zam'mbuyomu. Nthawi zambiri amakhulupirira kuti chifukwa chomwe tinthu tating'onoting'ono tomwe timatsekera m'mimba mwake ndi chifukwa cha: mphamvu za intermolecular (zomwe zimatchedwanso van der Waals attraction), kuphatikizapo dipole lokhazikika, dipole, dipole pompopompo komanso kukhalapo kwa njira yosinthira Ion.
