Okuqukethwe okuphezulu kwe-sodium, i-viscosity ephezulu, i-adsorption enamandla, ubumba lwensipho olusekelwe kwi-sodium

Amaminerali angewona awensimbi ane-montmorillonite njengokwakheka kwamaminerali okuyinhloko.

I-Bentonite iyi-mineral engeyona eyensimbi ene-montmorillonite njengengxenye yamaminerali eyinhloko, isakhiwo se-montmorillonite sakhiwe nge-silicon-oksijini tetrahedron ehlanganiswe nongqimba lwe-aluminium oksijini octahedron olwakhiwe 2:1 isakhiwo sekristalu, ngenxa yesakhiwo esinezingqimba esakhiwe iyunithi ye-montmorillonite. amaseli Kunama-cation athile, njenge-Cu, Mg, Na, K, njll., futhi lawa maseli eyunithi namayunithi e-montmorillonite awazinzile, kulula ukushintshaniswa ngamanye ama-cation, ngakho anokushintshana okungcono kwe-ion.Amazwe angaphandle asetshenziswe eminyangweni engaphezu kwe-100 emikhakheni ye-24 yokukhiqiza izimboni nezolimo, enemikhiqizo engaphezu kuka-300, ngakho abantu bayibiza ngokuthi "umhlabathi wendawo yonke".

I-Bentonite ibizwa nangokuthi i-porphyry, insipho yobumba noma i-bentonite.I-China inomlando omude wokuthuthukisa nokusebenzisa i-bentonite, ekuqaleni eyayisetshenziswa njengendawo yokuhlanza.(Kwakunezimayini zemigodi evulekile endaweni yaseRenshou eSichuan emakhulwini eminyaka edlule, futhi abantu bendawo babebiza i-bentonite njengofulawa wenhlabathi).Ineminyaka eyikhulu kuphela ubudala.I-United States yaqala ukutholwa esiqeshini sasendulo sase-Wyoming, ubumba oluphuzi oluluhlaza, olungakhula lube unamathisele ngemva kokwengeza amanzi, futhi kamuva abantu babiza lonke ubumba olunale ndawo ngokuthi i-bentonite.Eqinisweni, ingxenye eyinhloko yamaminerali ye-bentonite yi-montmorillonite, okuqukethwe yi-85-90%, kanti ezinye izakhiwo ze-bentonite nazo zinqunywe yi-montmorillonite.I-Montmorillonite ingaba nemibala ehlukahlukene efana nophuzi-oluhlaza, ophuzi-mhlophe, ompunga, omhlophe njalonjalo.Kungaba ibhulokhi elicinene, noma kungaba inhlabathi exegayo, futhi kuba nomuzwa oshelelayo lapho uhlikihlwa ngeminwe, futhi umthamo webhulokhi elincane unwebeka izikhathi ezimbalwa kuye izikhathi ezingama-20-30 ngemuva kokungeza amanzi, futhi umiswa emanzini. futhi unamathisele lapho amanzi emancane.Izakhiwo ze-montmorillonite zihlobene nokwakheka kwamakhemikhali kanye nesakhiwo sangaphakathi.
