Sodium Bentonite
Kamere
Sodium bentonite igabanijwe ukurikije ubwoko n'ibirimo bya cations zishobora guhindurwa hagati ya montmorillonite: imwe ifite coefficient ya alkalinity irenze cyangwa ingana na 1 ni sodium bentonite, naho iyifite coefficient ya alkaline iri munsi ya 1 ni calcium bentonite.
Ubushyuhe bwo kunanirwa bwa sodium bentonite yubukorikori buratandukanye bitewe na sodium itandukanye, ariko byose biri munsi yubwa sodium bentonite karemano;imbaraga zo kwaguka za sodium bentonite karemano nini kuruta iy'ubukorikori bwa sodium bentonite;c-axis itondekanya sodium naturite karemano iruta iy'ubukorikori bwa sodium bentonite, hamwe nintete nziza no gutatana gukomeye.Imiterere yumubiri nubumashini nibintu byikoranabuhanga bya Na bentonite biruta ibya Ca bentonite.Igaragarira cyane cyane: kwinjiza amazi gahoro, kwinjiza amazi menshi no kugereranya kwaguka;ubushobozi bwo guhanahana amakuru menshi;gutatanya neza mumazi yo hagati, igiciro kinini cya colloidal;thixotropy nziza, viscosity, lubricity, pH agaciro;umutekano mwiza;plastike nyinshi hamwe no gufatana gukomeye;ubushyuhe bushyushye butose imbaraga nimbaraga zumye.Kubwibyo, gukoresha agaciro nubukungu bwa sodium bentonite iri hejuru.Imiterere yumubiri na chimique ya sodium bentonite yubukorikori ntibiterwa gusa nubwoko nibirimo bya montmorillonite, ahubwo biterwa nuburyo nuburyo bwa sodium yubukorikori.
Umutungo wibicuruzwa

Gusaba
1. Mu gucukura neza, gutondeka ibyondo byo gutobora bifite amazi menshi na thixotropy.
2. Mu gukora imashini, irashobora gukoreshwa nko kubumba umucanga na binder, ishobora gutsinda ikibazo cyo "gushyiramo umucanga" na "gukuramo" ibishishwa, kugabanya igipimo cy’ibisambo, no kwemeza neza neza.
3. Ikoreshwa nkuzuza impapuro muruganda rwimpapuro kugirango uzamure urumuri rwimpapuro.
4. Irashobora gukoreshwa nka antistatike yo kwisiga aho kuba ingano ya krahisi no gucapa impapuro zo gucapa no gusiga irangi.
5. Mu nganda zibyuma, bentonite ikoreshwa nkumuhuza wamabuye yicyuma pellet, bigatuma ingano yubunini bwimyambaro yubutare hamwe nigabanuka ryibyiza, aribwo buryo bukoreshwa cyane na bentonite.
6. Mu nganda za peteroli, sodium bentonite ikoreshwa mugutegura amazi y’amazi.
7. Mu nganda zibiribwa, sodium bentonite ikoreshwa mugushushanya no kweza amavuta yinyamanswa nimboga, gusobanura vino numutobe, guhagarika byeri, nibindi.
8. Mu nganda zo gucapa no gusiga amarangi, sodium bentonite ikoreshwa nk'uzuza, imiti ihumanya, antistatike, ishobora gusimbuza ubunini bwa krahisi no gukora paste.
9. Birashobora kandi kuba inyongeramusaruro.
