Yintoni i-bentonite?

I-Bentonite iyiminerali yodongwe equlunqwe ngokukodwa i-montmorillonite, uhlobo lwe-smectite mineral.Yenziwe ngenxa yemozulu yothuthu lwentaba-mlilo kunye nezinye intlenga zentaba-mlilo, kwaye idla ngokufumaneka kwiindawo ezinentaba-mlilo ephezulu.I-Bentonite isetyenziswa ngokubanzi kumashishini ahlukeneyo, kuquka ukwakhiwa, ezolimo, kunye nokugaya, ngenxa yeempawu zayo ezizodwa.

I-Bentonite inesakhiwo esine-layer, kunye neengqimba zomntu ngamnye eziqulethwe ngamacwecwe e-silicon kunye ne-aluminium oxides edityaniswe omnye nomnye nge-athomu ye-oxygen.Iimaleko zibanjwa kunye ngamandla e-van der Waals, abuthathaka ngokwentelekiso, avumela amanzi kunye nezinye iimolekyuli ezincinci ukuba zingene phakathi kweeleya.Oku kunika i-bentonite amandla ayo okuvuvukala kunye nokufunxa amanzi, okwenza kube luncedo kwiinkqubo ezahlukeneyo.

Enye yezinto eziphambili zokusetyenziswa kwe-bentonite ifana nolwelo lokugaya kwishishini leoli kunye negesi.I-Bentonite yongezwa kwi-drilling muds ukuphucula i-viscosity yabo kunye neempawu zokumiswa, inceda ukuthutha i-cuttings cuttings out of the wellbore kunye nokuthintela ukuwa kweendonga ze-borehole.I-Bentonite iphinda incede ukulawula ukulahlekelwa kwamanzi, ukuthintela ukulahleka kodaka lokugaya kwiifom ze-porous.

I-Bentonite iphinda isetyenziswe ekwakhiweni njengenxalenye ye-grouts, i-mortar, kunye nekhonkrithi.Inokuphucula ukusebenza kunye nokuhamba kwezi zixhobo, ngelixa ukwandisa amandla kunye nokuqina kwazo.Kwizicelo zokuzinzisa umhlaba, i-bentonite ingasetyenziselwa ukuphucula iimpawu zomhlaba wodongwe, ukuthintela ukuvuvukala okugqithisileyo kunye nokunciphisa ngenxa yokutshintsha komswakama.

Kwezolimo, i-bentonite isetyenziswa njengesilungiso somhlaba ukuphucula ubume bomhlaba kunye nokugcinwa kwamanzi.Ingasetyenziselwa ukucacisa kunye nokuzinzisa iwayini, iijusi, kunye nokunye ukutya kunye neemveliso zesiselo.

Okunye ukusetyenziswa kwe-bentonite kubandakanya i-litter yekati, izimonyo, kunye namayeza.I-Bentonite ifunyenwe inezixhobo zokulwa ne-antibacterial kunye ne-antifungal, eyenza ibe luncedo kwiintlobo ezahlukeneyo zonyango.

Naphezu kokusetyenziswa kwayo okuninzi, i-bentonite ingaba neempembelelo ezimbi zokusingqongileyo ukuba ayiphathwa kakuhle.Ukusetyenziswa ngokugqithiseleyo kwe-bentonite kwi-drilling fluids kunokubangela ukuvala ukubunjwa, ngelixa ukulahlwa kwenkunkuma equkethe i-bentonite kunokukhokelela ekungcoleni komhlaba kunye namanzi aphantsi komhlaba.Ukulawula ngononophelo ukusetyenziswa kwe-bentonite kuyimfuneko ukunciphisa ezi mpembelelo.
