Bentonite ya sodium
Chilengedwe
Sodium bentonite imagawidwa molingana ndi mtundu ndi zomwe zili zosinthika pakati pa zigawo za montmorillonite: yemwe ali ndi alkalinity coefficient wamkulu kapena wofanana ndi 1 ndi sodium bentonite, ndipo yemwe ali ndi alkalinity coefficient zosakwana 1 ndi calcium bentonite.
Kulephera kutentha kwa yokumba sodium bentonite ndi osiyana chifukwa cha zinthu zosiyanasiyana sodium, koma onse ndi otsika kuposa zachilengedwe sodium bentonite;mphamvu yowonjezera ya sodium bentonite yachilengedwe ndi yayikulu kuposa ya bentonite ya sodium yokumba;dongosolo la c-axis la bentonite yachilengedwe ya sodium ndi yapamwamba kuposa ya bentonite ya sodium yochita kupanga, yokhala ndi njere zabwino komanso kubalalitsidwa kolimba.Zomwe zimagwiritsidwa ntchito ndi mankhwala komanso zamakono za Na bentonite ndizoposa za Ca bentonite.Imawonetseredwa makamaka mu: kuyamwa kwapang'onopang'ono kwa madzi, kuyamwa kwakukulu kwa madzi ndi chiŵerengero cha kukula;mkulu macation kuwombola mphamvu;kubalalitsidwa bwino mu sing'anga madzi, mkulu colloidal mtengo;zabwino thixotropy, mamasukidwe akayendedwe, lubricity, pH mtengo;kukhazikika kwamafuta abwino;high plasticity ndi amphamvu adhesion;mkulu kutentha konyowa konyowa mphamvu ndi youma kuthamanga mphamvu.Choncho, mtengo wogwiritsira ntchito komanso mtengo wamtengo wapatali wa sodium bentonite ndi wapamwamba.The thupi ndi mankhwala katundu wa yokumba sodium bentonite zimadalira osati pa mtundu ndi zili montmorillonite, komanso pa njira ndi digiri yokumba sodium.

Kugwiritsa ntchito
1. Pobowola bwino, kuyimitsidwa kwamatope obowola ndi madzi ochuluka komanso thixotropy amakonzedwa.
2. Pakupanga makina, angagwiritsidwe ntchito ngati kuumba mchenga ndi binder, zomwe zingathe kuthana ndi zochitika za "kuphatikiza mchenga" ndi "peeling" za castings, kuchepetsa kuchuluka kwa zidutswa zowonongeka, ndikuwonetsetsa kuti kulondola ndi kusalala kwa castings.
3. Amagwiritsidwa ntchito ngati chojambulira pamapepala kuti awonjezere kuwala kwa mapepala.
4. Itha kugwiritsidwa ntchito ngati zokutira antistatic m'malo mwa wowuma sizing ndi kusindikiza zokutira mu nsalu yosindikiza ndi utoto wamadzimadzi.
5. M'makampani opanga zitsulo, bentonite imagwiritsidwa ntchito ngati chomangira chachitsulo chachitsulo, chomwe chimapangitsa kuti tinthu tating'onoting'ono ta yunifolomu ya ore ikhale yabwino, yomwe ndi ntchito yaikulu kwambiri ya bentonite.
6. Mu mafuta a petroleum, sodium bentonite imagwiritsidwa ntchito pokonzekera emulsion yamadzi a phula.
7. M'makampani a zakudya, sodium bentonite imagwiritsidwa ntchito poyeretsa ndi kuyeretsa nyama ndi mafuta a masamba, kufotokozera vinyo ndi madzi, kukhazikika mowa, etc.
8. M'makampani osindikizira nsalu ndi utoto, sodium bentonite imagwiritsidwa ntchito ngati filler, bleaching agent, antistatic coating, yomwe imatha m'malo mwa wowuma ndikupanga phala losindikiza.
9. Itha kukhalanso chowonjezera cha chakudya.
