Pasi pemamiriro ehuwandu - mvura, bentonite crystal chimiro chakanyanya kunaka, uye iyi yakakosha yakanaka yekristaro chimiro inoona kuti ine akawanda akanakisa maitiro:
(1) Kunwa mvura
Munzvimbo ine hydrated yakazara, nzvimbo yepakati inogona kuwedzerwa, uye vhoriyamu mushure mekutora mvura inogona kuwedzerwa nel0 ~ 30 nguva.
(2) Kumiswa
Bentonite mineral zvikamu zvidiki (pazasi 0.2μm), zviri nyore kupatsanura pakati peyuniti crystal layer uye iyo crystal layer yekrisitive mushure merdration yakazara, ichigadzira collid ine mvura. Mukuwedzera, nekuti masero emontmortilon ane nhamba yakafanana yezvakaipa, anodzinganisa. Zvakaoma kuunganidzira kuita zvidimbu zvakakura mumhinduro dzeDilute. Kana iyo pH yekumiswa kwemvura iri> 7, kuwedzera kwakasimba uye kumiswa kwemhedzisiro kuri nani.
(3) Thixotropy
Iro hydroxyl boka muchimiro richagadzira hydrogen zvisungo mu static medium, zvichiita kuti ive yunifomu gel ine imwe viscosity. Kana ichimutswa pamberi pekunze kwesimba rekucheka, iyo hydrogen zvisungo ichaparadzwa uye viscosity ichave isina simba. Nokudaro, kana bentonite inogadziriswa yakasvibiswa, kusungirirwa kuchaita se sol - mvura ine mvura yakanaka, uye kana kuputika kwekunze kunomira, ichazvironga pachayo kuva gel ine matatu - dimensional network structure. Iko hakuna kugadzirisa delamination uye kupatsanurwa kwemvura, uye kana simba rekunze rinoshandiswa kushungurudza, gel rinogona kukurumidza kuputswa uye fluidity inogona kudzorerwa. Hunhu uhu hunoita kuti bentonite ive yakakosha mukumiswa.
(4) kubatana
Kubatana kwakaunzwa nekuvhengana kwe bentonite Uye mvura inobva kune zvakawanda zvikamu, zvakadai seBentonite hydrophilic, zvakashata zvimedu zvemari, hydroxyl pamusoro mafomu eHydrogen.
(5) Adsorption
Mushure mokunge Al3 + inotsiviwa nemaion akasiyana mu bentonite, kusaenzana kwemhosva yemukati kunokonzerwa nekugadzira magetsi adsorption centre. Panguva imwecheteyo, montmorillonite ine yakakura yakananga nzvimbo nekuda kweiyo yakasarudzika bioctahedral chimiro uye laminate musanganiswa, saka ine yakakwira dhigirii yekusarudza adsorption.
(6) Ion kuchinjana
Kubva pakuona kwemaitiro, bentonite inoumbwa nezvikamu zviviri zve silica tetrahedron ine chidimbu chealuminium oxide octahedron pakati, mutengo wepamusoro unogona kuchinjwa nemutengo wakaderera cation muchitokisi, zvichiita kuti kusaenzana kwemhosva muchikwata. layer, bentonite yakachajiswa zvisina kunaka, uye inofanirwa kutora imwe inogona kuchinjana K+, Na+, ca2+, Mg2+ kubva kunharaunda yakatenderedza kuti ienzanise mutero. Iyo inonyanya kuchinjika cations ndeye ca2 + uye Na +, saka, zvichienderana nerudzi uye huwandu hwekuchinjana cations dzirimo.
(7) Kugadzikana
Bentonite inogona kumira 300 ℃ yakakwirira tembiricha, ine yakanaka yekudziya kugadzikana, isinganyungudika mumvura, inonyungudika zvishoma muasidhi yakasimba, hwaro hwakasimba, pakupisa kwekamuri haina oxidized kana kuderedzwa, isinganyungudika muorganic solvents. Iine kugadzikana kwakanaka kwemakemikari.
(8) Non-chepfu
Bentonite Haisi - ine chepfu uye inokoshesa kuvanhu, zvipfuyo nezvidyarwa, hapana kukurudzira kweganda revanhu, hapana kukanganisa kwehurongwa hwekutya uye hwekufema, uye kunogona kushandiswa semutakuri wemishonga.
