I-bentonite ekhethekileyo ye-gel ye-organic ephezulu yokwemba ulwelo

Ngenxa yolwakhiwo oluthile lwe-bentonite, inendawo enkulu yendawo ethile, ngoko ine-adsorption enamandla, kwaye ngenxa yobukho beqela le-hydrophilic OH-, inokusasazwa okugqwesileyo, ukumiswa kunye nokubambelela kwisisombululo esinamanzi, kwaye ibonisa i-thixotropy egqwesileyo. kuluhlu oluthile loxinaniso.Okokuthi, xa kukho ukuvuselela kwangaphandle, ulwelo lokumiswa lubonakala njenge-sol kunye ne-fluidity enhle, kwaye emva kokuyeka ukuvuselela, kuya kuzilungiselela kwijel kunye nesakhiwo sothungelwano ngaphandle kwe-sedimentation kunye nokuhlukana kwamanzi.Le propati ifaneleka ngokukodwa ekuqulunqweni kodaka lokugaya.Kungakhathaliseki ukuba i-oyile i-oyile okanye i-geological exploration drilling, inani elikhulu le-bentonite lisetyenziswa njengeyona nto iphambili yokulungisa udaka lokugaya ukukhusela udonga lwamaqula, ukusika amatye aphezulu, ukupholisa i-drill. amasuntswana, njl.

I-Bentonite iyona nto ibaluleke kakhulu yendalo yamaminerali esetyenziselwa ukulungelelanisa i-rheology kunye ne-filtration properties ze-drilling fluids.I-Bentonite, esetyenziselwa njengento yokugaya amanzi, ngokuqhelekileyo i-sodium-based bentonite, kunye ne-calcium-based bentonite kufuneka isetyenziswe emva kwe-sodification.Ukuguqulwa kwezinto eziphilayo ze-bentonite ngokuqhelekileyo kukufaka i-organic matter phakathi kwe-montmorillonite layers kunye nokwenza indawo ye-cation phakathi kwe-montmorillonite layers;Kwangaxeshanye, kukho namaqela amaninzi e-hydroxyl kunye namaqela asebenzayo kumphezulu wamasuntswana e-montmorillonite kunye neefractures ze-lateral ze-crystals, ezinokugxunyekwa kunye ne-polymerized nge-alkene monomers phantsi kweemeko ezithile.Injongo yayo ikakhulu kukuphucula i-adsorption kunye ne-hydration, ukuphucula isiphumo sokulahlekelwa kwesihluzi se-bentonite kunye nobuchule be-synergistic kunye nezinye ii-arhente zonyango.
