Ukunyibilika: I-EDTA 4NA iyancibilika emanzini ne-asidi, ayincibiliki otshwaleni ne-benzene.
Ukuzinza: Izinzile.Akuhambisani nama-oxidizing agents aqinile.
Izimo zokugcina: Gcina endaweni epholile, engenamoya futhi eyomile, evikelekile elangeni nasemvuleni.
Inqubo yomkhiqizo:
Itholakala ekuphenduleni kwe-ethylenediamine nge-chloroacetic acid, noma ekuphenduleni kwe-ethylenediamine nge-formaldehyde ne-sodium cyanide.
Izici:
I-EDTA 4NA i-white crystalline powder iqukethe amanzi angamakristalu angu-4, ancibilika kalula emanzini, isixazululo esinamanzi sine-alkaline, sincibilika kancane kuzincibilikisi eziphilayo njenge-ethanol, singalahlekelwa ingxenye noma wonke amanzi ekristalu ekushiseni okuphezulu.
Izicelo:
I-EDTA 4NA iyinsimbi ye-ion chelator esetshenziswa kabanzi.
1. Ingasetshenziswa embonini yendwangu ukudaya, ukuthuthukisa umbala, ukuthuthukisa umbala nokukhanya kwezindwangu ezidayiwe.
2. Isetshenziswa njenge-additive, activator, i-metal ion masking agent kanye ne-activator embonini yenjoloba ye-butadiene.
3. Ingasetshenziswa embonini eyomile ye-acrylic ukuze isuse ukuphazamiseka kwensimbi.
4. I-EDTA 4NA ingasetshenziswa futhi kumshini wokuhlanza uketshezi ukuthuthukisa ikhwalithi yokuwasha kanye nomphumela wokuwasha.
5. Isetshenziswa njengesithambisi samanzi, isihlanzi samanzi, esisetshenziselwa ukwelashwa kwekhwalithi yamanzi.
6. Isetshenziswa njenge-synthetic rubber catalyst, i-acrylic polymerization terminator, izinsiza zokuphrinta nokudaya, njll.
7. Iphinde isetshenziselwe i-titration ekuhlaziyweni kwamakhemikhali, futhi ingahlanganisa ngokunembile izinhlobonhlobo ze-ion zensimbi.
8. Ngaphezu kwalokhu kusetshenziswa okungenhla, i-EDTA 4NA ingasetshenziswa futhi kwezemithi, kumakhemikhali ansuku zonke, ekwenzeni amaphepha nakwezinye izimboni.
