Product process:
Inowanikwa kubva pakuita kwe ethylenediamine ne chloroacetic acid, kana kubva pakuita kwe ethylenediamine ne formaldehyde uye sodium cyanide.
Features:
EDTA 4NA ichena crystalline poda ine 4 crystal mvura, inonyungudika zviri nyore mumvura, aqueous solution is alkaline, zvishoma soluble muorganic solvents senge ethanol, inogona kurasikirwa nechikamu kana yese yekristaro mvura pakupisa kwakanyanya.
Applications:
EDTA 4NA inoshandiswa zvakanyanya simbi ion chelator.
1. Inogona kushandiswa muindasitiri yemachira kudhayira, kuwedzera ruvara, kuvandudza ruvara uye kupenya kwemachira akadhayiwa.
2. Inoshandiswa sekuwedzera, activator, metal ion masking agent uye activator mubutadiene rubber industry.
3. Inogona kushandiswa mune yakaoma acrylic indasitiri kuti kubvisa simbi kupindira.
4. EDTA 4NA inogonawo kushandiswa mumushonga wemvura kuti uvandudze kushambidzika kwehutano uye maitiro ekugeza.
5. Inoshandiswa semvura inopfava, yekuchenesa mvura, inoshandiswa pakurapa kwemhando yemvura.
6. Inoshandiswa seyakagadzirwa rabha catalyst, acrylic polymerization terminator, kudhinda uye dhayi ebetsero, nezvimwe.
7. Inoshandiswawo kune titration mukuongorora kwemakemikari, uye inogona kunyatsogadzirisa zvakasiyana-siyana zvesimbi ions.
8. Pamusoro pekushandiswa kwepamusoro, EDTA 4NA inogonawo kushandiswa mumishonga, makemikari ezuva nezuva, kugadzira mapepa uye mamwe maindasitiri.
