Daim ntawv thov
EthylenedIninetetraiacetic acid tetrasodium (Edta-4na) yog cov neeg sawv cev ntau yam siv ntau yam ntawm kev lag luam:
Kev kho cov dej:
Raws li cov dej muag dej, Edta-4Na tuaj yeem chelate nyuaj ions xws li calcium thiab magnesium, tiv thaiv kev tsim kom muaj kev nplua, thiab txhim kho cov dej ua kom zoo. Hauv cov boiler descaling, nws lub peev xwm chelating tuaj yeem txo cov peev txheej tso tawm, txhim kho kev ua haujlwm kom khov, thiab nws qhov ruaj khov ntawm cov tshuaj kub zoo dua li cov tshuaj phosphates zoo dua.
Textile thiab luam ntawv thiab Dyeing:
Edta-4na yog siv los ua qhov dyeing pab kom tshem tawm cov kev cuam tshuam ntawm cov hlau ions ntawm dyes thiab xim ceev ceev. Hauv Acrylic Fiber ua, raws li kev pib, nws tuaj yeem txhim kho cov tshuaj pleev cov fiber ntau thiab lub zog.
Kev Lag Luam Txhua Hnub:
Edta-4na txhim kho lub peev xwm ntxuav ntawm surfactants hauv kev xab npum thiab tiv thaiv kev tiv thaiv tsis ua haujlwm los ntawm cov hlau ion catalytic oxidation. Cov tshuaj ntxuav tawv tawv kom txo cov dej ntws los ntawm chelating hlau impurities.
Kws Kev Lag Luam:
Edta-48na tuaj yeem siv los kho cov hlau hnyav (xws li cov hmoov txhuas thiab mercury excetion; Txo hypercalcemia thiab txo kom txo nqi xacim.
Kev Lag Luam Khoom Noj:
Edta-48na tuaj yeem tiv thaiv cov hlau ions los ntawm oxidizing cov khoom noj khoom noj khoom haus thiab muab txee rau lub neej. Siv los ua kom muaj zog calcium ions hauv cov zaub mov mos thiab khoom noj mis nyuj, zam cov protein nag lossis daus.
Roj Hmab Thiab Yas:
Thaum lub sij hawm polymerization ntawm styrene butadiene roj hmab, edta-4na yog siv los ua ib tug activator los txhim kho cov kev sib txawv ntawm cov kev faib tawm hnyav molecular; Chelate hlau impurities nyob rau hauv pvc ua los tiv thaiv kev catalytic oxidation.
Ntawv thiab luam ntawv:
Edta-48 tuaj yeem txhim kho cov dej tsis kam ua thiab txhim kho tshuaj dawb; Ruaj khov nab kuab sawv daws kom txo cov hlau ion kev cuam tshuam.
Chaw ntim khoom
Lub Warehouse yog cua thiab qhuav ntawm qhov kub tsis qhuav. Zam kev ua tshav ntuj ncaj qha thiab kev nqus dej noo.
