Cov Neeg Muag Khoom Zoo Muag Khoom Kub Muag Chelating Agent 99% Assay Dawb Qauv CAS 64-02-8 EDTA Tetrasodium EDTA 4na Sodium Edetate
Peb ntseeg hais tias kev sib koom ua ke mus sij hawm ntev yog los ntawm kev ua tau zoo, muaj txiaj ntsig ntxiv, kev nplua nuj thiab kev sib cuag ntawm tus kheej rau Cov Neeg Muag Khoom Zoo Muag Kub Muag Chelating Agent 99% Assay Dawb Qauv CAS 64-02-8 EDTA Tetrasodium EDTA 4na Sodium Edetate, Peb yuav muab cov kev daws teeb meem zoo thiab cov tuam txhab zoo heev ntawm cov nqi hnyav.Pib tau txais txiaj ntsig los ntawm peb cov neeg muab kev pabcuam dav dav los ntawm kev tiv tauj peb hnub no.
Peb ntseeg hais tias kev sib koom ua lag luam mus sij hawm ntev yog qhov ua tau zoo, muaj txiaj ntsig ntxiv kev pabcuam, kev nplua nuj kev paub thiab kev sib cuag rau tus kheejTuam Tshoj EDTA thiab EDTA 99% Min, Peb paub meej txog peb cov neeg siv khoom xav tau.Peb muab cov khoom zoo, cov nqi sib tw thiab cov kev pabcuam thawj zaug.Peb xav tsim kom muaj kev lag luam kev sib raug zoo nrog rau kev phooj ywg nrog koj nyob rau yav tom ntej.
Cov khoom no yog cov xim tsis muaj xim lossis yellowish siab viscous kua.Soluble hauv dej, ethanol, hygroscopic, insoluble hauv benzene thiab acetone.Cov dej nag yuav tshwm sim thaum nws ua tau raws li sulfuric acid nrog tus nqi pH qis dua 2.4.Cov tshuaj aqueous yog qhov zoo them, thiab qhov sib ntxiv ntawm formaldehyde tsim cov hws.Nws yog siv los ua tus neeg sawv cev ntub dej ntawm cov ntawv ua tsis taus pa, thiab tus neeg sawv cev tuav thiab ntaus tus neeg sawv cev hauv cov txheej txheem ntawm papermaking tuaj yeem txo qhov kev ntaus nqi ntawm pulp.Txhim kho lub peev xwm dewatering ntawm daim ntawv.Qhov qhuav ntawm daim ntawv yog nce los ntawm 1% - 4%.Lub peev xwm ntau lawm yog nce los ntawm 5% - 20%.

1. Siv los ua tus neeg saib xyuas lub zog ntub dej ntawm cov ntawv tsis muaj qhov ua pa, tuav tus neeg saib xyuas thiab tus neeg sawv cev ntaus hauv cov txheej txheem ntawm papermaking, uas tuaj yeem txo qhov kev ntaus nqi ntawm cov pulp.Txhim kho lub peev xwm dewatering ntawm daim ntawv.Qhov qhuav ntawm daim ntawv yog nce los ntawm 1% - 4%.Lub peev xwm ntau lawm yog nce los ntawm 5% - 20%.
2. Siv dav hauv kev luam ntawv number case, txheej, nplaum thiab lwm yam.
3. Siv nyob rau hauv papermaking dej kho, electroplating tov thiab dispersant.
4. Siv ua epoxy resin reagent, aldehyde adsorbent thiab dye fixative.
Ntim rau hauv 25kgs nruas thiab khaws cia kom deb ntawm lub teeb ntawm qhov kub ntawm 25 ℃.
