Inkqubo yemveliso:
Ifunyenwe kwi-reaction ye-ethylenediamine kunye ne-chloroacetic acid, okanye kwi-reaction ye-ethylenediamine kunye ne-formaldehyde kunye ne-sodium cyanide.
Iimbonakalo:
I-EDTA 4NA i-white crystalline powder iqulethe i-4 crystal yamanzi, i-soluble kalula emanzini, isisombululo esinamanzi yi-alkaline, i-soluble kancinane kwi-solvents yezinto eziphilayo ezifana ne-ethanol, inokulahlekelwa inxalenye okanye onke amanzi e-crystal kwiqondo lokushisa eliphezulu.
Usetyenziso:
I-EDTA 4NA isetyenziswa ngokubanzi i-ion chelator yensimbi.
1. Ingasetyenziswa kwishishini lelaphu lokudaya, ukuphucula umbala, ukuphucula umbala kunye nokuqaqamba kwamalaphu adayiweyo.
2. Isetyenziswe njenge-additive, activator, i-agent ion masking agent kunye ne-activator kwishishini le-rubber ye-butadiene.
3. Ingasetyenziselwa kwishishini elomileyo le-acrylic ukucima ukuphazamiseka kwesinyithi.
4. I-EDTA 4NA ingasetyenziselwa isicoci solwelo ukuphucula umgangatho wokuhlamba kunye nesiphumo sokuhlamba.
5. Isetyenziswa njengesithambisi samanzi, isicoci samanzi, sisetyenziselwa unyango lomgangatho wamanzi.
6. Isetyenziswe njenge-raber catalyst yokwenziwa, i-acrylic polymerization terminator, ukuprinta kunye nokudaya abancedisi, njl.
7. Kwakhona isetyenziselwa i-titration kuhlalutyo lweekhemikhali, kwaye iyakwazi ukubethelela ngokuchanekileyo iindidi ze-ion zetsimbi.
8. Ukongeza kolu setyenziso lungasentla, i-EDTA 4NA isenokusetyenziswa kwakhona kwikhemikhali, kwikhemikhali yemihla ngemihla, ekwenzeni amaphepha nakwamanye amashishini.
