Isilinganiso sokuxuba i-bentonite odakeni lokumba singahluka kuye ngokuthi izidingo ezithile zomsebenzi wokumba kanye nohlobo lodaka lokumba olusetshenziswayo. I-Bentonite iyisici esiyinhloko sokumba udaka, futhi injongo yayo eyinhloko ukuthuthukisa i-viscosity kanye nezakhiwo zokugcoba zodaka. Isilinganiso esifanele sengxube sibalulekile ekuzuzeni ukusebenza kahle kodaka lokumba.
Ngokuvamile, i-bentonite ixubene namanzi ukuze yenze i-slurry, futhi isilinganiso sokuxuba sivezwa njengenani le-bentonite (ngesisindo) elingezwe kumthamo othize wamanzi. Izici ezifiselekayo zodaka lokumba, njenge-viscosity, amandla ejeli, nokulawulwa kokuhlunga, kuthonya ukukhethwa kwe-mix ratio.
Izici eziningana zithonya ukuzimisela kwesilinganiso sokuxuba, kuhlanganise nohlobo lwe-bentonite esetshenzisiwe (i-bentonite ye-sodium noma i-calcium bentonite), izimo zokumba, kanye nezidingo ezithile zokusebenza kokumba. Lezi zici kufanele zicatshangelwe ukuze zenze udaka lokumba luhambisane nezici ze-geological zokubunjwa okumbayo.
I-sodium bentonite wuhlobo lwe-bentonite oluvame ukusetshenziselwa ukumba ukwakheka kodaka. Isilinganiso esivamile sokuxuba sobumba be-sodium bentonite singamakhilogremu angu-20 kuya kwangu-35 wobumba be-bentonite ngamalitha angu-100 amanzi. Nokho, lesi silinganiso singalungiswa ngokusekelwe ezidingweni ezithile nezimo zokumba.
I-calcium bentonite, ngakolunye uhlangothi, ingadinga isilinganiso esihlukile sokuxuba uma kuqhathaniswa ne-sodium bentonite. Ukukhethwa phakathi kwe-bentonite ye-sodium ne-calcium bentonite kuncike ezintweni ezifana nezindawo zoketshezi olufunayo, usawoti woketshezi lokumba, kanye nezici ze-geological zokwakheka.
Ngokungeziwe esilinganisweni esiyisisekelo sokuxuba, ukwakheka kodaka lokumba kungaqukatha ezinye izithasiselo zokuthuthukisa ukusebenza. Lezi zengezo zingabandakanya ama-polymer, ama-viscosifiers, ama-ejenti okulawula uketshezi, nama-ejenti okulinganisa. Ukusebenzisana phakathi kwe-bentonite nalezi zithako kucatshangelwa ngokucophelela ukuze kuzuzwe izakhiwo ezifunwayo ze-rheological kanye nezici zodaka zokumba.
Kubalulekile ukuthi ochwepheshe bokubhola benze ukuhlolwa kwaselabhorethri kanye nezivivinyo zasensimini ukuze bakhulise izilinganiso zemiksi emisebenzini ethile yokumba. Umgomo wawuwukwakha udaka lokumba oluzothwala ngempumelelo izimbobo zokubhoboza phezulu, lunikeze ukuzinza kumgodi, futhi luhlangabezane nezidingo zemvelo kanye nokulawula kwendawo yokumba.
I-mix ratio ye-bentonite edaka lokumba iyipharamitha ebalulekile ehluka ngokusekelwe ezicini ezifana nohlobo lwe-bentonite, izimo zokumba kanye nezakhiwo zodaka ezidingekayo. Ochwepheshe bemboni yokumba bahlola ngokucophelela lezi zici ukuze banqume isilinganiso esifanele sokuxutshwa komsebenzi othile wokumba, baqinisekise imiphumela ephumelelayo, ephumelelayo yokumba.
