High Purity EDTA-2na Impurity Control thiab International Ua Raws Cai

High purity EDTA-2Na yog tsuas yog muab rau cov tshuaj pleev ib ce, khoom noj khoom haus additives thiab tshuaj raw khoom lag luam, uas tso rau pem hauv ntej tsis tshua muaj kev cai rau impurity tswj thiab kev nyab xeeb ua raws. Kev tsim khoom thiab xa tawm cov lag luam yuav tsum ua raws li cov txheej txheem thoob ntiaj teb los tswj cov hlau hnyav, chloride, sulfate thiab insoluble impurities nyob rau hauv kev txwv tsis pub dhau.

 

Nyob rau hauv cov txheej txheem ntau lawm ntawm siab -purity EDTA-2Na, ntau recrystallization, pom thiab purification txheej txheem yog ntxiv raws li cov pa synthesis. Kev soj ntsuam nruj raw khoom yog siv los txo cov kev taw qhia ntawm kab impurities los ntawm qhov chaw, thiab xyuas kom meej tias cov khoom muaj cov ntsiab lus tseem ceeb thiab cov yam ntxwv tsis zoo ntawm cov khoom seem.

 

Core impurity tswj cov ntsuas muaj xws li txhuas, arsenic, cadmium thiab lwm yam hlau hnyav, nrog rau cov dej insoluble teeb meem, chloride thiab sulfate cov ntsiab lus. Cov hlau hnyav ntau dhau yuav ua rau muaj kev nyab xeeb rau cov tshuaj pleev ib ce thiab cov khoom siv tshuaj, thaum cov teeb meem insoluble ntau dhau yuav cuam tshuam rau cov khoom tawg thiab cov tsos tsis sib xws.

 

Kev ua raws cai thoob ntiaj teb cov qauv tseem ceeb suav nrog cov txheej txheem kev nyab xeeb ntawm cov khoom siv tshuaj pleev ib ce, cov khoom noj khoom haus additive grade qauv thiab REACH cov cai rau npe ntawm European lag luam. Siab -purity EDTA-2Na rau kev xa tawm yuav tsum ua kom tiav cov kev ntsuas cuam tshuam thiab ntawv pov thawj kom ua tiav kev soj ntsuam kev lis kev cai thiab cov neeg yuav khoom hauv lub Hoobkas nkag mus kuaj.

 

Cov neeg yuav khoom koom nrog siab -kawg zoo tshuaj raw khoom ntshuam ua tib zoo saib xyuas lub Hoobkas tsim nyog thiab thib peb-cov ntaub ntawv xeem ntawmEDTA-2 Na. Ua tiav cov ntaub ntawv ua raws cai thiab qib kev tswj hwm tsis huv yog qhov tseem ceeb rau kev ua haujlwm ntev - kev koom tes ntawm cov neeg muag khoom thiab thoob ntiaj teb siab - cov neeg siv khoom kawg.

 

Rau cov tuam txhab xa tawm tshuaj, ua raws li qib siab -purity ntau lawm qauv thiab nruj impurity tswj yuav qhib siab -kawg kev lag luam raws, tshem tawm ntawm qis- nqi homogenization kev sib tw, thiab txhim kho cov khoom lag luam ntxiv thiab kev sib tw thoob ntiaj teb kev lag luam.
