1. Core Dissolution Data (25 degree, dej ntshiab, txheem nplawm)
| Yam khoom | EDTA Disodium (EDTA-2Na) hmoov | EDTA Tetrasodium (EDTA-4Na) |
|---|---|---|
| Solubility siab tshaj | ~10 g/L | ~60 g/L |
| Dissolution ceev | qeeb; yuav tsum tau ntev stirring | ceev heev; dissolves yuav luag tam sim ntawd |
| Dissolution xeev | Ib qho yooj yim los tsim lumps / undissolved hais | Tsis muaj caking, uniform tov |
| Yuav tsum tau stirring lub sij hawm | 10-20 mins rau tag nrho dissolution | 1-3 mins rau tag nrho dissolution |
2. Kev ua tau zoo ntawm Automated Production Lines
EDTA-2 Na
Qhov tsis zoo:
Tsawg solubility tsis tuaj yeem npaj siab -cov ntsiab lus cov ntsiab lus, txwv kev noj zaub mov kom zoo.
Kev sib xyaw qeeb qeeb thiab kev pheej hmoo ua rau cov khoom tsis sib xws, uas txhaws cov kav dej, lim dej, cov nozzles hauv cov kab txuas txuas ntxiv.
Xav tau txuas ntxiv stirring lossis cua sov, ncua sij hawm lub voj voog thiab nce lub zog noj.
Muaj cov xwm txheej: Tsuas yog yooj yim sib tshuam batch ntau lawm,tsis pom zoo rau tus qauv automated kab.
EDTA-4 Na
Qhov zoo:
Kev tawg sai sai yoog mus rau siab - ceev nruam noj cov khoom siv tsis siv neeg.
Kev solubility siab txhawb nqa cov kua dej ntau ntxiv, txiav cov ntim ntim, khaws cia thiab cov nqi thauj mus los.
Tsis muaj sediment los yog lumps, ruaj khov khoom xa tuaj, txo cov khoom tu thiab downtime.
Muaj cov xwm txheej: Thawj qhov kev xaiv rau tag nrho cov kab ntau lawm(industrial detergents, textile, alkaline dej kho, kua chiv thiab lwm yam).
3. Kev txiav txim zaum kawg
EDTA Tetrasodium (EDTA-4Na) yog qhov zoo dua rau cov kab ntau lawm.
Cov Lus Qhia Ntxiv
EDTA-4Na muaj zog alkaline; tsis txhob sib tov ncaj qha nrog cov khoom siv acidic kom tiv thaiv nag lossis daus.
Yog tias koj cov kab hluav taws xob tsis siv neeg tsim cov khoom nruab nrab / tsis muaj zog acidic (khoom noj khoom haus, tshuaj pleev ib ce), lo rau EDTA-2Na thiab ua ntej yaj nws ua ntej nrog kev nplawm txaus.
