Daim ntawv thov
Cov kaus poom kimchi
EDTA muaj antioxidant zog thiab muaj zog chelating nyhuv ntawm hlau ions, ua rau nws ib tug stabilizer. Peb lub teb chaws tau hais tias nws tuaj yeem siv tau rau Pickled zaub thiab cov kaus poom zaub mov, thiab qhov siv ntau tshaj plaws yog 0.25g/kg.
ntxhua khaub ncaws
Ntawm cov ntsev ntawm EDTA, disodium ntsev yog qhov tseem ceeb tshaj plaws. EDTA disodium ntsev yog ib qho tseem ceeb complexing neeg sawv cev rau complexing hlau ions thiab cais kub chemobooks. Nws kuj tseem siv tau rau hauv cov tshuaj ntxuav tes, xab npum ua kua, tshuaj zawv plaub hau, tshuaj tua kab mob, cov khoom siv xim xim, tshuaj pleev xim, tshuaj ntxuav dej, pH regulators, anion coagulants, thiab lwm yam.
Txheej
EDTA feem ntau yog siv rau hauv cov nplaum, fiber ntau winding, laminates, cov txheej txheem kev ua haujlwm siab, thiab cov txheej txheej hauv lub tank, ua tus neeg saib xyuas rau epoxy resins thiab cov saw txuas rau polyurethane monome.
