I-Sodium Bentonite
Imvelo
I-sodium bentonite ihlukaniswa ngokohlobo nokuqukethwe kwama-cations ashintshayo phakathi kwezingqimba ze-montmorillonite: leyo ene-alkalinity coefficient enkulu noma elingana no-1 i-sodium bentonite, kanti leyo ene-alkalinity coefficient engaphansi kuka-1 i-calcium bentonite.
Ukushisa okuhlulekayo kwe-bentonite ye-sodium yokufakelwa kuhlukile ngenxa yezimo ezihlukene ze-sodium, kodwa zonke ziphansi kune-bentonite yemvelo ye-sodium;amandla okunwetshwa kwe-sodium bentonite yemvelo inkulu kune-bentonite ye-sodium yokufakelwa;i-c-axis oda ye-sodium bentonite yemvelo iphakeme kunaleyo ye-sodium bentonite yokwenziwa, enezinhlamvu ezinhle kanye nokuhlakazeka okuqinile.Izakhiwo zomzimba namakhemikhali kanye nezobuchwepheshe be-Na bentonite ziphakeme kune-Ca bentonite.Ibonakaliswa ngokuyinhloko: ukumuncwa kwamanzi kancane, ukumuncwa kwamanzi aphezulu kanye nesilinganiso sokwandisa;amandla okushintshanisa ama-cation aphezulu;ukuhlakazeka okuhle emanzini, intengo ephezulu ye-colloidal;i-thixotropy enhle, i-viscosity, i-lubricity, inani le-pH;ukuzinza okuhle kokushisa;ipulasitiki ephezulu kanye nokunamathela okuqinile;amandla okuqina aphezulu ashisayo ashisayo namandla okucindezela okomile.Ngakho-ke, inani lokusetshenziswa kanye nenani lezomnotho le-sodium bentonite liphakeme.Izakhiwo zomzimba nezamakhemikhali ze-sodium bentonite yokufakelwa azixhomeki kuphela ohlotsheni nokuqukethwe kwe-montmorillonite, kodwa futhi endleleni kanye nezinga le-sodium yokufakelwa.
Impahla yomkhiqizo
| I-Montmorillonite | 60% - 88% |
| Umthamo wokunweba | 25-50ml / g |
| Inani le-Colloidal | ≥ 99ml / 15g |
| 2 h ukumuncwa amanzi | 250-350% |
| Okuqukethwe kwamanzi | ≥ 12 |
| Amandla okucindezela okumanzi | ≥ 0.23 (MPA) |
| Ukumuncwa okuhlaza okwesibhakabhaka ≥ 80mmol / 100g | |
| I-Na2O ≥ 1.28 | |
Isicelo
1. Ekubambeni kahle, ukumiswa kodaka lokumba nge-fluidity ephezulu kanye ne-thixotropy ihlelwe.
2. Ekukhiqizeni ngomshini, ingasetshenziswa njengesihlabathi sokubumba kanye ne-binder, enganqoba isenzakalo "sokufakwa kwesihlabathi" kanye "nokucwecwa" kokubunjwa, ukunciphisa izinga le-scrap of castings, futhi kuqinisekiswe ukunemba nokushelela kokusakazwa.
3. Isetshenziswa njengokugcwalisa iphepha embonini yamaphepha ukuze kuthuthukiswe ukugqama kwamaphepha.
4. Ingasetshenziswa njenge-antistatic coating esikhundleni sokulinganisa isitashi nokuphrinta okokuphrinta ku-textile printing kanye noketshezi lokudaya.
5. Embonini ye-metallurgical, i-bentonite isetshenziswa njenge-binder ye-iron ore pellet, eyenza ubukhulu bezinhlayiyana ze-ore uniform kanye nokusebenza kokunciphisa kube kuhle, okuwukusetshenziswa okukhulu kwe-bentonite.
6. Embonini ye-petroleum, i-bentonite ye-sodium isetshenziselwa ukulungisa i-emulsion yamanzi e-tar.
7. Embonini yokudla, i-sodium bentonite isetshenziselwa ukukhipha umbala nokuhlanza amafutha ezilwane nemifino, ukucacisa iwayini nejusi, ukuzinzisa ubhiya, njll.
8. Embonini yokunyathelisa yendwangu kanye nokudaya, i-sodium bentonite isetshenziswa njenge-filler, i-ejenti ye-bleaching, i-antistatic coating, engashintsha ukulinganisa isitashi futhi yenze ukunamathisela kokuphrinta.
9. Kungaba futhi isengezo sokuphakelayo.
