Product Description:
Dawb crystalline hmoov, melting point 240 ° C (decomposition). Insoluble nyob rau hauv dej txias, cawv thiab cov organic solvents, me ntsis soluble nyob rau hauv dej kub, soluble nyob rau hauv cov kev daws ntawm sodium hydroxide, sodium carbonate thiab ammonia.
Daim ntawv thov:
(1) Siv los ua cov tshuaj dawb thiab kho kom zoo rau kev ua cov ntaub ntawv xim xim, dyeing auxiliaries, fiber ntau kho auxiliaries, cosmetic additives, ntshav anticoagulants, detergents, stabilizers, hluavtaws roj hmab polymerisation pib, EDTA yog ib tug neeg sawv cev tshuaj rau chelating agents.
(2) Nws tuaj yeem tsim cov dej-soluble complexes ruaj khov nrog alkaline ntiaj teb hlau, tsis tshua muaj ntiaj teb cov ntsiab lus thiab cov hlau hloov pauv. Ntxiv nrog rau cov ntsev ntsev, tseem muaj ammonium ntsev thiab hlau, magnesium, calcium, tooj liab, manganese, zinc, cobalt, txhuas thiab lwm yam ntsev, txhua yam ntawm cov ntsev no muaj kev siv sib txawv.
(3) EDTA kuj tuaj yeem siv los tshem tawm cov teeb meem hluav taws xob hlau los ntawm tib neeg lub cev hauv cov txheej txheem tshem tawm sai. Nws kuj yog siv los ua tus neeg sawv cev kho dej.
(4) EDTA yog qhov taw qhia tseem ceeb thiab tuaj yeem siv rau titrate npib tsib xee, tooj liab, thiab lwm yam. Nws yuav tsum tau siv ua ke nrog ammonia los ua qhov taw qhia.
