Gukemura: EDTA 4NA irashobora gushonga mumazi na aside, idashobora gushonga muri alcool na benzene.
Igihagararo: gihamye.Ntibishobora gukoreshwa na okiside ikomeye.
Imiterere yububiko: Bika ahantu hakonje, uhumeka kandi wumye, urinzwe izuba n imvura.
Igicuruzwa:
Bikomoka ku myitwarire ya Ethylenediamine hamwe na aside ya chloroacetike, cyangwa bivuye kuri Ethylenediamine hamwe na formaldehyde na sodium cyanide.
Ibiranga:
EDTA 4NA ni ifu yera ya kristaline irimo amazi 4 ya kirisiti, gushonga byoroshye mumazi, igisubizo cyamazi ni alkaline, gishonga gato mumashanyarazi kama nka Ethanol, irashobora gutakaza igice cyangwa amazi ya kristu yose mubushyuhe bwinshi.
Porogaramu:
EDTA 4NA nicyuma gikoreshwa cyane.
1. Irashobora gukoreshwa mu nganda z’imyenda mu gusiga irangi, kuzamura amabara, kunoza ibara nuburanga bwimyenda irangi.
2. Ikoreshwa nk'inyongera, ikora, icyuma cya ion masking agent na activateur mu ruganda rwa butadiene.
3. Irashobora gukoreshwa munganda zumye za acrylic kugirango ziveho ibyuma.
4. EDTA 4NA irashobora kandi gukoreshwa mumazi yo kwisiga kugirango yongere ubwiza no gukaraba.
5. Ikoreshwa nk'iyoroshya amazi, isukura amazi, ikoreshwa mugutunganya amazi meza.
6. Ikoreshwa nka catalizike ya rubber ya catalizike, terminator ya acrylic polymerisation, gucapa no gusiga amarangi, nibindi.
7. Irakoreshwa kandi muri titre mu isesengura ryimiti, kandi irashobora gutanga titre neza ion zitandukanye.
8. Usibye imikoreshereze yavuzwe haruguru, EDTA 4NA irashobora kandi gukoreshwa mubuvuzi, imiti ya buri munsi, gukora impapuro nizindi nganda.
