Khoom Paub meej

EDTA-4Na yog tag nrho neutralized sodium ntsev ntawm ethylenediaminetetraacetic acid, muab los ua dawb crystalline hmoov los yog granular khoom. Nrog rau tag nrho plaub pawg carboxyl hloov mus rau hauv sodium ntsev, cov khoom lag luam nthuav tawm cov dej solubility siab heev thiab dissolves sai heev los tsim cov kev daws teeb meem tsis muaj qhov seem turbidity. A 1% aqueous tov feem ntau qhia tau hais tias muaj zog alkalinity, nrog pH ntau ntawm kwv yees li 10.5-11.5, uas txawv EDTA-4Na los ntawm ib nrab neutralized EDTA ntsev.

Daim ntawv sodium ntsev ua tiav no ua ke ob qho kev ua haujlwm zoo hauv ib qho khoom siv. Ntawm ib sab tes, nws tuav lub zog thiab dav chelating peev xwm ntawm EDTA, ua tau zoo losis tswvyim dabtsi divalent thiab trivalent hlau ions xws li Ca²⁺, Mg²⁺, Fe³⁺, thiab Cu²⁺. Ntawm qhov tod tes, nws cov alkalinity inherent tso cai rau nws los pab rau pH hloov thiab buffering nyob rau hauv alkaline systems, txo los yog ib feem hloov qhov xav tau rau cais alkali ntxiv nyob rau hauv tej yam txheej txheem.

Hauv kev ua textile, EDTA-4Na plays lub luag haujlwm tseem ceeb los ntawm kev kho ua ntej los ntawm dyeing. Thaum lub sij hawm desizing, scouring, thiab tshwj xeeb tshaj yog hydrogen peroxide bleaching, kab hlau ions tuaj yeem catalyze uncontrolled peroxide decomposition, ua rau fiber ntau puas, uneven whiteness, thiab txo cov txheej txheem efficiency. EDTA-4Na sai sai ua rau cov ions no, stabilizing lub bleaching da dej thiab kom tswj tau oxidation thaum khaws cia fiber ntau zog thiab ntaub zoo.

Nyob rau hauv reactive dyeing ntawm paj rwb, EDTA-4Na tseem ua raws li cov dej softener thiab hlau ion sequestrant, tiv thaiv kev cuam tshuam nrog dye fixation. Nyob rau tib lub sijhawm, nws qhov xwm txheej alkaline pab tswj kom muaj cov xim zoo nkauj da dej pH, txhawb kev kho cov tshuaj tiv thaiv zoo ib yam thiab txhim kho ntxoov ntxoo rov tsim dua ntawm cov xim ntau.

Tshaj li textiles, EDTA-4Na yog dav siv nyob rau hauv industrial tu thiab dej kho rau scale tshem tawm thiab hardness tswj, nyob rau hauv detergents thiab tsev chemicals los txhim kho kev ua hauj lwm tu, thiab nyob rau hauv kev ua liaj ua teb raws li ib tug chelating carrier rau micronutrient chiv. Nws ua ke ntawm kev solubility ceev, muaj zog chelation, thiab alkalinity ua rau nws tshwj xeeb tshaj yog haum rau cov txheej txheem uas yuav tsum tau npaj sai thiab ua haujlwm nyob rau hauv alkaline tej yam kev mob.

EDTA

Taw qhia: EDTA yog ib qho siv ntau thiab muaj txiaj ntsig zoo hlau ion chelating tus neeg sawv cev uas tuaj yeem ruaj khov khi hlau ions xws li calcium, magnesium, hlau, thiab tooj liab, tshem tawm lawv cuam tshuam nrog lub cev. Nws yog dav siv nyob rau hauv textile printing thiab dyeing, dej kho, detergents, kws, zaub mov, thiab industrial tu, rau softening dej, stabilizing cov tshuaj tiv thaiv, thiab kev txhim kho cov khoom zoo thiab cov txheej txheem stability.
