Inkqubo yemveliso:
Ifunyanwa kwimpendulo ye-ethylenediamine kunye ne-chloroacetic acid, okanye kwimpendulo ye-ethylenediamine kunye ne-formaldehyde kunye ne-sodium cyanide.
Iimbonakalo:
I-EDTA 4NA ngumgubo omhlophe wekristale oqulethe amanzi ekristale ama-4, anyibilika lula emanzini, isisombululo samanzi si-alkaline, sinyibilika kancinci kwizinyibilikisi ze-organic ezifana ne-ethanol, sinokulahlekelwa yinxalenye okanye yiyo yonke ikristale yamanzi kubushushu obuphezulu.
Izicelo:
I-EDTA 4NA sisixhobo esisetyenziswa kakhulu ekuphembeleleni ii-ion zesinyithi.
1. Ingasetyenziswa kwishishini leempahla zokudaya, ukuphucula umbala, ukuphucula umbala kunye nokukhanya kweempahla ezidayiweyo.
2. Isetyenziswa njenge-additive, activator, metal ion masking agent kunye ne-activator kwishishini lerabha le-butadiene.
3. Ingasetyenziswa kwishishini le-acrylic elomileyo ukuphelisa ukuphazamiseka kwesinyithi.
4. I-EDTA 4NA ingasetyenziswa nakwisepha yolwelo ukuphucula umgangatho wokuhlamba kunye nempembelelo yokuhlamba.
5. Isetyenziswa njengesithambisi-manzi, isicoci samanzi, isetyenziselwa unyango lomgangatho wamanzi.
6. Isetyenziswa njengesixhobo sokulungisa irabha esenziwe ngokwenziwa, isiphelisi se-acrylic polymerization, izincedisi zokuprinta kunye nokudaya, njl.
7. Ikwasetyenziselwa ukuhluza i-titration kuhlalutyo lweekhemikhali, kwaye inokuhluza ngokuchanekileyo i-ioni ezahlukeneyo zesinyithi.
8. Ukongeza kokusetyenziswa okungentla, i-EDTA 4NA ingasetyenziswa nakwimizi-mveliso yamayeza, iikhemikhali zemihla ngemihla, ukwenza amaphepha kunye neminye imimandla.
