Maitiro echigadzirwa:
Inowanikwa kubva mukusangana kwe ethylenediamine ne chloroacetic acid, kana kubva mukusangana kwe ethylenediamine ne formaldehyde uye sodium cyanide.
Zvimiro:
EDTA 4NA ihupfu hwemakristaro machena hune mvura ina dzemakristaro, inonyungudika nyore mumvura, mvura ine alkaline, inonyungudika zvishoma muzvinhu zvinonyungudutsa zvakaita seethanol, inogona kurasikirwa nemvura yese kana chikamu chayo pakupisa kwakanyanya.
Mashandisirwo:
EDTA 4NA isimbi inoshandiswa zvakanyanya inonzi ion chelator.
1. Inogona kushandiswa muindasitiri yemachira pakudhaya, kuwedzera ruvara, kuvandudza ruvara nekupenya kwemachira akadhayiwa.
2. Inoshandiswa sechinowedzera, chinosimudzira, chinovhara ion yesimbi uye chinosimudzira muindasitiri yerabha yebutadiene.
3. Inogona kushandiswa muindasitiri yeacrylic yakaoma kudzivirira kukanganiswa kwesimbi.
4. EDTA 4NA inogona kushandiswawo mu sipo yemvura kuti ivandudze kunaka kwekuwacha uye simba rekusuka.
5. Inoshandiswa sechinonyorovesa mvura, chinochenesa mvura, uye inoshandiswa pakuchenesa mvura.
6. Inoshandiswa senzira yekugadzira rabha, acrylic polymerization terminator, kudhinda uye kudhaya machira, nezvimwewo.
7. Inoshandiswawo pakuongorora maitikiro esimbi, uye inogona kuyera maitikiro esimbi akasiyana-siyana nemazvo.
8. Pamusoro pekushandiswa kuri pamusoro apa, EDTA 4NA inogonawo kushandiswa mumishonga, makemikari ezuva nezuva, kugadzira mapepa nemamwe maindasitiri.
