I-Sodium Bentonite
Indalo
I-bentonite ye-sodium yahlulwe ngokohlobo kunye nomxholo we-cations exchangeable between layers of montmorillonite: enye ene-alkalinity coefficient enkulu okanye elingana ne-1 yi-sodium bentonite, kunye ne-alkalinity coefficient engaphantsi kwe-1 yi-calcium bentonite.
Ukushisa kokungaphumeleli kwe-sodium bentonite eyenziwe yahlukile ngenxa yeemeko ezahlukeneyo ze-sodium, kodwa zonke ziphantsi kune-bentonite ye-sodium yendalo;amandla okwandiswa kwe-sodium bentonite yendalo inkulu kune-bentonite ye-sodium eyenziweyo;i-c-axis order ye-bentonite ye-sodium yendalo iphezulu kune-bentonite ye-sodium eyenziweyo, eneengqolowa ezintle kunye ne-dispersion enamandla.Iimpawu ezibonakalayo kunye neekhemikhali kunye nezobuchwepheshe ze-Na bentonite ziphezulu kunezo zeCa bentonite.Ibonakaliswa ngokuyintloko: ukufunxa amanzi okucothayo, ukufunxa kwamanzi aphezulu kunye nomlinganiselo wokwandisa;umthamo wotshintshiselwano nge-cation ephezulu;ukusasazwa kakuhle kumbindi wamanzi, ixabiso eliphezulu le-colloidal;i-thixotropy enhle, i-viscosity, i-lubricity, ixabiso le-pH;ukuzinza okuhle kwe-thermal;iplastiki ephezulu kunye nokunamathela okuqinileyo;amandla aphezulu obushushu obumanzi kunye namandla oxinzelelo olomileyo.Ngoko ke, ixabiso lokusetyenziswa kunye nexabiso lezoqoqosho ze-sodium bentonite ziphezulu.Iimpawu zomzimba kunye neekhemikhali ze-sodium bentonite eyenziweyo azixhomekanga kuphela kuhlobo kunye nomxholo we-montmorillonite, kodwa nakwindlela kunye neqondo le-sodium yokwenziwa.
Ipropathi yemveliso

Isicelo
1. Ekubhobhozeni kakuhle, ukumiswa kodaka lokugaya kunye ne-fluidity ephezulu kunye ne-thixotropy ihlelwe.
2. Kwimveliso yomatshini, ingasetyenziselwa njengesanti yokubumba kunye ne-binder, enokuthi inqobe isiganeko "sokufakwa kwesanti" kunye ne "peeling" ye-castings, ukunciphisa izinga le-scrap of castings, kunye nokuqinisekisa ukuchaneka kunye nokuguquguquka kwe-castings.
3. Isetyenziswa njengesizalisi sephepha kushishino lwamaphepha ukunyusa ukuqaqamba kwamaphepha ephepha.
4. Ingasetyenziswa njenge-antistatic yokwambathisa endaweni yokulinganisa isitatshi kunye nokuprinta ukutyabeka kushicilelo lwelaphu kunye nolwelo lokudaya.
5. Kwi-industry metallurgical, i-bentonite isetyenziswe njenge-binder ye-iron ore pellet, eyenza i-particle size ye-ore uniform kunye nokunciphisa ukusebenza kakuhle, eyona nto isetyenziswa kakhulu ye-bentonite.
6. Kwishishini le-petroleum, i-sodium bentonite isetyenziselwa ukulungisa i-emulsion yamanzi e-tar.
7. Kwishishini lokutya, i-bentonite ye-sodium isetyenziselwa i-decolorize kwaye ihlambulule ioli yezilwanyana kunye nemifuno, ukucacisa iwayini kunye nejusi, ukuzinzisa ubhiya, njl.
8. Kwishishini lokuprinta i-textile kunye nokudaya, i-bentonite ye-sodium isetyenziswa njenge-filler, i-ejenti ye-bleaching, i-antistatic coating, enokuthi ithathe indawo ye-starch sizeing kunye ne-printing paste.
9. Kwakhona inokuba sisongezo sokutya.
