Yini i-bentonite?

I-Bentonite iyimaminerali yobumba eyakhiwe ngokuyinhloko i-montmorillonite, uhlobo lwe-smectite mineral. Yakheka ngenxa yesimo sezulu somlotha wentaba-mlilo nezinye izinsalela zentaba-mlilo, futhi ngokuvamile itholakala ezindaweni ezinentaba-mlilo ephezulu. I-Bentonite isetshenziswa kabanzi ezimbonini ezihlukahlukene, kuhlanganise nezokwakha, ezolimo, nokumba, ngenxa yezakhiwo zayo eziyingqayizivele.

I-Bentonite inesakhiwo esinezingqimba, ezinezingqimba ngazinye ezihlanganisa amashidi e-silicon nama-aluminium oxides ahlanganiswe omunye nomunye ngama-athomu omoya-mpilo. Izingqimba zibanjwe ndawonye amandla e-van der Waals, abuthakathaka uma kuqhathaniswa, avumela amanzi namanye ama-molecule amancane ukuba angene phakathi kwezingqimba. Lokhu kunikeza i-bentonite ikhono layo lokuvuvukala nokumunca amanzi, okwenza kube usizo emisebenzini ehlukahlukene.

Enye yezindlela eziyinhloko ezisetshenziswa ngayo i-bentonite iwuketshezi lokumba embonini kawoyela negesi. I-Bentonite yengezwa ekubhobozeni udaka ukuze kuthuthukiswe i-viscosity yabo kanye nezakhiwo zokumiswa, ukusiza ukuthutha ukusika ukumba ngaphandle komthombo futhi kuvimbele ukuwa kwezindonga ze-borehole. I-Bentonite iphinde isize ukulawula ukulahlekelwa kwamanzi, ukuvimbela ukulahlekelwa kodaka lokumba lube yizimbotshana.

I-Bentonite nayo isetshenziselwa ukwakhiwa njengengxenye yama-grouts, udaka, nokhonkolo. Ingathuthukisa ukusebenza nokugeleza kwalezi zinto, kuyilapho ikhulisa amandla nokuqina kwazo. Ekusetshenzisweni kokuqiniswa kwenhlabathi, i-bentonite ingasetshenziswa ukuthuthukisa izakhiwo zenhlabathi yobumba, ukuvimbela ukuvuvukala ngokweqile nokunciphisa ngenxa yezinguquko zomswakama.

Kwezolimo, i-bentonite isetshenziswa njengesichibiyelo senhlabathi ukuze kuthuthukiswe ukwakheka kwenhlabathi nokugcinwa kwamanzi. Ingase futhi isetshenziselwe ukucacisa kanye nokusimamisa iwayini, amajusi, neminye imikhiqizo yokudla neziphuzo.

Okunye ukusetshenziswa kwe-bentonite kufaka phakathi udoti wekati, izimonyo, kanye nemithi. I-Bentonite itholakale inezinto zokulwa ne-antibacterial kanye ne-antifungal, okwenza kube usizo ezinhlobonhlobo zezicelo zezokwelapha.

Naphezu kokusetshenziswa kwayo okuningi, i-bentonite ingaba nemithelela emibi yemvelo uma ingaphathwa kahle. Ukusetshenziswa ngokweqile kwe-bentonite emanzini okumba kungabangela ukuvinjelwa kokwakheka, kuyilapho ukulahlwa kwemfucuza equkethe i-bentonite kungaholela ekungcolisweni komhlabathi namanzi angaphansi komhlaba. Ukuphatha ngokucophelela ukusetshenziswa kwe-bentonite kuyadingeka ukuze kuncishiswe le mithelela.
