Inqubo yomkhiqizo:
Itholakala ekusabeleni kwe-ethylenediamine ne-chloroacetic acid, noma ekusabeleni kwe-ethylenediamine ne-formaldehyde ne-sodium cyanide.
Izici:
I-EDTA 4NA iyimpuphu emhlophe ekristalu equkethe amanzi amakristalu ama-4, ancibilika kalula emanzini, isixazululo samanzi siyi-alkaline, sincibilika kancane ezinyibilikisini eziphilayo ezifana ne-ethanol, singalahlekelwa yingxenye noma wonke amanzi ekristalu ekushiseni okuphezulu.
Izicelo:
I-EDTA 4NA iyi-chelator ye-ion yensimbi esetshenziswa kabanzi.
1. Ingasetshenziswa embonini yezindwangu ukudaya, ukuthuthukisa umbala, ukuthuthukisa umbala nokukhanya kwezindwangu ezidaywe.
2. Isetshenziswa njengesengezo, isiqalisi, i-ejenti yokufihla ama-ion ensimbi kanye nesiqalisi embonini yerabha ye-butadiene.
3. Ingasetshenziswa embonini ye-acrylic eyomile ukuze kulungiswe ukuphazamiseka kwensimbi.
4. I-EDTA 4NA ingasetshenziswa futhi ekuhlanzeni okuwuketshezi ukuthuthukisa ikhwalithi yokuwasha kanye nomphumela wokuwasha.
5. Isetshenziswa njengesithambisi samanzi, isihlanzi samanzi, isetshenziselwa ukwelashwa kwekhwalithi yamanzi.
6. Isetshenziswa njenge-catalyst yerabha yokwenziwa, i-acrylic polymerization terminator, izinsiza zokunyathelisa nokudaya, njll.
7. Iphinde isetshenziswe ekuhlaziyeni amakhemikhali, futhi ingalinganisa ngokunembile izinhlobo ezahlukene zama-ion ensimbi.
8. Ngaphezu kokusetshenziswa okungenhla, i-EDTA 4NA ingasetshenziswa nasezimbonini zemithi, zamakhemikhali zansuku zonke, ekwenziweni kwephepha nakwezinye izimboni.
