Bentonite isiri-metallic mineral ine montmorillonite seyo huru mineral component.Iyo montmorillonite chimiro ndeye 2: 1 mhando yekristaro chimiro chinoumbwa maviri silicon oxide tetrahedron akaiswa sandwich ne layer yealuminium oxide octahedron.Nekuda kweiyo yakaturikidzana dhizaini yakaumbwa ne montmorillonite crystal cell, kune mamwe ma cations, akadai seCu, Mg, Na, K, nezvimwewo, uye kudyidzana pakati peiyi cations uye montmorillonite crystal cell haina kugadzikana, zviri nyore kuve. yakatsinhaniswa nemamwe cations, saka ine yakanaka ion exchange properties.Kumhiri kwemakungwa, yakashandiswa mumadhipatimendi anopfuura zana muminda makumi maviri nemana ekugadzirwa kwemaindasitiri nekurima, ine zvigadzirwa zvinopfuura mazana matatu, saka vanhu vanoidana kuti "ivhu repasi rose".
Bentonite inozivikanwawo se bentonite, bentonite, kana bentonite.China ine nhoroondo yakareba yekugadzira nekushandisa bentonite, iyo yakatanga kushandiswa se detergent.(Kwaive nemigodhi yakavhurika munzvimbo yeRenshou yeSichuan mazana emakore apfuura, uye vanhu veko vainzi bentonite ivhu rehupfu.).Yakangoshandiswa zvakanyanya kweanopfuura makore zana.Kuwanikwa kwekutanga muUnited States kwaive munharaunda yekare yeWyoming, uko ivhu reyero-girinhi, iro rinogona kuwedzera kuita dongo mushure mekuwedzera mvura, rakange richinzi bentonite.Muchokwadi, iyo huru yemaminerari chikamu chebentonite ndeye montmorillonite, ine zvinyorwa zve85-90%.Zvimwe zvinhu zve bentonite zvinotemerwawo ne montmorillonite.Montmorillonite inogona kutora mavara akasiyana seyero yegirini, yero chena, grey, chena, zvichingodaro.Inogona kuumba mapundu akakora kana ivhu rakasununguka, nekunzwa kutsvedza kana uchikweshwa neminwe yako.Mushure mekuwedzera mvura, muviri muduku unowedzera kakawanda kusvika ku20-30 nguva muhuwandu, uye inoratidzika yakamiswa mumvura.Kana paine mvura shoma, inoita kunge mushy.Izvo zvimiro zve montmorillonite zvine chekuita nemakemikari ayo uye chimiro chemukati.
Natural bleached ivhu
Sezvineiwo, ivhu chena rinongoitika riine bleaching properties ivhu jena, jena grey rinonyanya kuumbwa nemontmorillonite, albite, uye quartz, uye imhando yebentonite.
Icho chinonyanya kugadzirwa kwekuparara kwevitreous volcanic rock, iyo isingawedzere mushure mekutora mvura, uye pH kukosha kwekusimirirwa haina simba acid, iyo yakasiyana nealkaline bentonite;Kuita kwayo kuchena kwakaipa kupfuura kwevhu rakagadzirwa.Iwo mavara anowanzo sanganisira mwenje yero, girini chena, grey, olive ruvara, brown, mukaka chena, peach tsvuku, bhuruu, zvichingodaro.Vashoma vachena chena.Density: 2.7-2.9g/cm.Iyo inooneka density kazhinji yakaderera nekuda kweporosity.Mushonga wekemikari wakafanana nevhuwo zvaro, rine makemikari makuru ealuminium oxide, silicon dioxide, mvura, uye shoma shoma yesimbi, magnesium, calcium, nezvimwewo. Hapana plastiki, yakakwirira adsorption.Nekuda kwehuwandu hwehuwandu hwe hydrous silicic acid, ine acidic kune litmus.Mvura inowanzoputika uye ine mvura yakawanda.Kazhinji, kutsetseka kwacho, ndiko kuwedzera kwesimba re decolorization.
Munguva yechikamu chekuongorora, kana uchiitisa kuongororwa kwemhando, zvinodikanwa kuyera kuita kwayo kuchena, acidity, kusefa kuita, kunyura kwemafuta, uye zvimwe zvinhu.
Bentonite ore
Bentonite ore iminerari ine mashandisirwo akawanda, uye kunaka kwayo uye minda yekushandisa inonyanya kuenderana nezviri mukati uye hunhu rudzi rwemontmorillonite uye makristasi ayo emakemikari zvimiro.Naizvozvo, kukura kwayo uye kushandiswa kunofanirwa kusiyana kubva kune yangu kuenda kune yangu uye kubva pakuita basa kuenda kune rimwe basa.Semuenzaniso, kugadzirwa kwevhu rakagadzirwa, calcium yakavakirwa kune sodium yakavakirwa, kuchera grouting yekuchera petroleum, kutsiva starch senge slurry yekuruka, kudhinda uye dhayi, uchishandisa mukati uye kunze kwemadziro machira pazvinhu zvekuvaka, kugadzirira organic bentonite, synthesizing 4A zeolite. kubva ku bentonite, kubudisa white carbon black, nezvimwewo.
Musiyano pakati pecalcium based uye sodium based
Mhando ye bentonite inotarirwa nemhando ye interlayer cation mu bentonite.Kana iyo interlayer cation iri Na +, inonzi sodium based bentonite;Calcium yakavakirwa bentonite inodanwa kana iyo interlayer cation iri Ca +.Sodium montmorillonite (kana sodium bentonite) ine zvivakwa zviri nani pane calcium based bentonite.Zvisinei, kugovewa kwevhu recalcareous munyika kwakakura zvikuru kupfuura kwevhu resodium.Nokudaro, kunze kwekusimbisa kutsvaga kwevhu re sodium, zvakakosha kugadzirisa ivhu re calcareous kuti riite ivhu re sodium.
