I-bentonite ekhethekile ye-gel ephilayo yokumba uketshezi

Ngenxa yesakhiwo esithile esinezingqimba ze-bentonite, inendawo enkulu ethize, ngakho-ke ine-adsorption eqinile, futhi ngenxa yokuba khona kweqembu le-hydrophilic OH-, inokuhlakazeka okuhle kakhulu, ukumiswa nokunamathela kusixazululo samanzi, futhi ikhombisa i-thixotropy enhle kakhulu. ebangeni elithile lokuhlushwa.Okungukuthi, uma kukhona ukugqugquzela kwangaphandle, uketshezi lokumiswa luvela njenge-sol ene-fluidity enhle, futhi ngemva kokuyeka ukugqugquzela, izozihlela ibe ijeli enesakhiwo senethiwekhi ngaphandle kokuthungatha nokuhlukaniswa kwamanzi.Lesi sakhiwo sifaneleka ngokukhethekile ekwakhiweni kodaka lokumba.Kungakhathaliseki ukuthi ukumba uwoyela noma ukumba i-geological exploration, inani elikhulu le-bentonite lisetshenziswa njengezinto ezisetshenziswayo eziyinhloko ukulungisa udaka lokumba ukuze kuvikelwe udonga lomthombo, ukusika amatshe phezulu, ukubhola okupholisayo. izingcezu, njll.

I-Bentonite iyinto ebaluleke kakhulu yemvelo yamaminerali esetshenziselwa ukulungisa izakhiwo ze-rheology nokuhlunga uketshezi lokumba.I-Bentonite, esetshenziswa njengento yokumba uketshezi, ngokuvamile i-bentonite esekelwe ku-sodium, futhi i-bentonite esekelwe ku-calcium idinga ukusetshenziswa ngemva kokufakwa kwe-sodification.Ukuguqulwa kwezinto eziphilayo ze-bentonite ngokuvamile ukufaka izinto eziphilayo phakathi kwezingqimba ze-montmorillonite futhi kwenze ukushintshwa kwe-cation phakathi kwezingqimba ze-montmorillonite;Ngesikhathi esifanayo, kukhona namaqembu amaningi e-hydroxyl namaqembu asebenzayo ebusweni bezinhlayiya ze-montmorillonite kanye nokuhlukana kwe-lateral kwamakristalu, okungaxhunyelelwa futhi kwenziwe i-polymerized nge-alkene monomers ngaphansi kwezimo ezithile.Inhloso yayo ngokuyinhloko ukuthuthukisa i-adsorption yayo kanye ne-hydration, ukuthuthukisa umphumela wokulahlekelwa kwesihlungi se-bentonite kanye nekhono le-synergistic namanye ama-ejenti okwelapha.
