Bentonite isiri-metallic mineral inonyanya kuumbwa ne montmorillonite.The montmorillonite structure is a 2:1 type crystal structure inoumbwa netwo silica tetrahedra sandwiched with a layer of aluminium oxide octahedra.Nekuda kweiyo yakaturikidzana dhizaini yakaumbwa ne montmorillonite crystal masero, kune mamwe cations, akadai Cu, Mg, Na, K, nezvimwewo, uye kudyidzana kwavo nemontmorillonite crystal masero hakuna kugadzikana, izvo zviri nyore kuchinjana nemamwe cations. saka vane yakanaka ion exchange properties.Kunze kwenyika, yakashandiswa mumadhipatimendi anopfuura zana muminda makumi maviri nemana yekugadzira maindasitiri 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.Kwakanga kune migodhi yakavhurika munzvimbo yeRenshou yeSichuan mazana emakore apfuura, uye vagari veko vaiti bentonite seupfu hwevhu.Inoshandiswa zvakafara zvechokwadi asi inongova nenhoroondo yeanopfuura makore zana.Kuwanikwa kwekutanga muUnited States kwaive munharaunda yekare yeWyoming, uko ivhu reyero rakasvibirira, iro rinogona kuwedzera kuita dongo mushure mekuwedzera mvura, raiwanzonzi bentonite.Muchokwadi, iyo huru yemaminerari chikamu chebentonite ndeye montmorillonite, ine zvinyorwa zve85-90%.Zvimwe zvinhu zve bentonite zvinotemerwawo ne montmorillonite.Montmorillonite inogona kuoneka mumarudzi akasiyana-siyana seyero yegirini, yero chena, grey, chena, zvichingodaro.Inogona kuumba zvidhinha zvakakora kana ivhu rakasununguka, ine manzwiro ekutsvedza kana ichikwizwa neminwe.Mushure mekuwedzera mvura, vhoriyamu yezvidhinha zvidiki inowedzera kakawanda kusvika ku20-30 nguva, ichionekwa mune yakamiswa mamiriro mumvura, uye mune paste state kana paine mvura shoma.Izvo zvimiro zve montmorillonite zvine chekuita nemakemikari ayo uye chimiro chemukati.

Activated ivhu

Activated clay is an adsorbent yakagadzirwa kubva kuvhu (kunyanya bentonite) seyakabikwa, iyo inoiswa pasi pe inorganic acidification kurapwa, ichiteverwa nekusuka kwemvura nekuomesa.Chitarisiko chayo chine mukaka chena poda, isinganhuhwi, isinganakidze, isina chepfu, uye ine yakasimba adsorption performance.Inogona adsorb mavara uye organic zvinhu.Zviri nyore kutora hunyoro mumhepo, uye kuiisa kwenguva yakareba kunoderedza adsorption performance.Nekudaro, kupisa kusvika pamusoro pe300 madhigirii Celsius kunotanga kurasikirwa nemvura inopenya, zvichikonzera shanduko yezvimiro uye kukanganisa mhedzisiro.Ivhu rakabatidzwa harinyungudike mumvura, organic solvents, nemafuta akasiyana siyana, anenge akanyatso kunyungudika mune inopisa caustic pasoda uye hydrochloric acid, ine hama density ye2.3-2.5, uye kushoma kuzvimba mumvura nemafuta.

Natural bleached ivhu

Ivhu chena rinongo itika rine machenera evhu ivhu chena, jena grey ivhu rinonyanya kuumbwa ne montmorillonite, albite, uye quartz, uye imhando ye bentonite.
Kunyanya chigadzirwa chekuparara kwegirazi matombo emakomo, asingawedzere mushure mekutora mvura, uye pH kukosha kwekusimisa kwakasiyana neiyo alkaline bentonite;Kuita kwayo kuchena kwakaipa kupfuura kwevhu rakagadzirwa.Mavara acho anowanzo sanganisira yero yero, girini jena, grey, ruvara rweolive, brown, mukaka chena, pichisi tsvuku, bhuruu, nezvimwewo. Kune mashoma mashoma machena.Density 2.7-2.9g/cm.Iyo inooneka density inowanzove yakaderera nekuda kwe porosity yayo.Mushonga wekemikari wakafanana nevhuwo zvaro, rine makemikari makuru ealuminium oxide, silicon dioxide, mvura, uye shoma shoma yesimbi, magnesium, calcium, nezvimwewo. Hapana plasticity, ine high adsorption capacity.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.

Bentonite ore
Bentonite ore iminerari ine mashandisirwo akawanda, uye kunaka kwayo.
