Ndondomeko yamalonda:
Iwo analandira zimene ethylenediamine ndi chloroacetic asidi, kapena zimene ethylenediamine ndi formaldehyde ndi sodium cyanide.
Mawonekedwe:
EDTA 4NA ndi ufa woyera wa crystalline uli ndi madzi a kristalo 4, osungunuka mosavuta m'madzi, njira yamadzimadzi ndi yamchere, yosungunuka pang'ono mu zosungunulira za organic monga ethanol, zimatha kutaya gawo kapena madzi onse a kristalo pa kutentha kwakukulu.
Mapulogalamu:
EDTA 4NA ndi chitsulo chogwiritsidwa ntchito kwambiri ndi ion chelator.
1. Itha kugwiritsidwa ntchito pamakampani opanga nsalu popaka utoto, kukulitsa mtundu, kukonza utoto ndi kuwala kwa nsalu zopaka utoto.
2. Amagwiritsidwa ntchito ngati zowonjezera, activator, metal ion masking agent ndi activator mu makampani a rabara a butadiene.
3. Ikhoza kugwiritsidwa ntchito mu mafakitale owuma a acrylic kuti athetse kusokoneza kwazitsulo.
4. EDTA 4NA itha kugwiritsidwanso ntchito mu zotsukira zamadzimadzi kuti zithandizire kuchapa komanso kuchapa.
5. Amagwiritsidwa ntchito ngati chofewa chamadzi, chotsuka madzi, chogwiritsidwa ntchito pochiza madzi.
6. Ntchito monga kupanga mphira chothandizira, akiliriki polymerization terminator, kusindikiza ndi utoto wothandiza, etc.
7. Amagwiritsidwanso ntchito ngati titration pakuwunika kwamankhwala, ndipo amatha kutsitsa molondola ma ion achitsulo osiyanasiyana.
8. Kuphatikiza pa zomwe zili pamwambazi, EDTA 4NA ingagwiritsidwenso ntchito pamankhwala, mankhwala a tsiku ndi tsiku, kupanga mapepala ndi mafakitale ena.
