EDTA 2 Na

1 Hauv kev lag luam khoom noj, cov tshuaj tiv thaiv ntawm propylene glycol thiab fatty acid los tsim propylene glycol fatty acid ester yog siv los ua zaub mov emulsifier.
2 Propylene glycol feem ntau yog siv los ua cov kuab tshuaj, emollient thiab excipient hauv kev lag luam kws tshuaj.
3 Propylene glycol kuj tseem siv los ua cov kuab tshuaj thiab cov tshuaj softener hauv cov tshuaj pleev ib ce vim nws zoo sib xws nrog ntau yam txuj lom.
4 Propylene glycol kuj tseem siv los ua tus neeg haus luam yeeb ntub dej, tshuaj tiv thaiv kab mob, txiv hmab txiv ntoo ripening preservative, antifreeze thiab cua sov tus neeg saib xyuas.

EDTA SERIES khoom

Taw qhia

EDTA, los yog ethylenediaminetetraacetic acid, yog ib tug chelating neeg sawv cev lug siv nyob rau hauv kev lag luam,

zaub mov thiab chaw kho mob. EDTA yog tsim los ntawm alkaline cyanomethylation ntawm ethylene.

diamine nrog sodium cyanide thiab formaldehyde. Cov txheej txheem chelation yog stabilized

hlau ion, tiv thaiv nws los ntawm reacts chemically nrog lwm yam tshuaj. EDTA yog

Nws yog tsim nyob rau hauv daim ntawv ntawm ntau ntsev, tshwj xeeb tshaj yog disodium EDTA thiab calcium disodium EDTA.

Nqe lus:

EDTA yog ib qho tseem ceeb chelating tus neeg saib xyuas nrog rau kev siv dav. Nws tuaj yeem siv rau hauv detergents, dye additives, fiber ntau kho cov neeg ua haujlwm, tshuaj pleev ib ce additives, zaub mov additives, ntshav anticoagulants, dej purification agents, ua liaj ua teb chiv, thiab lwm yam.

EDTA tuaj yeem tsim cov dej-soluble complexes ruaj khov nrog cov hlau alkali, cov ntsiab lus tsis tshua muaj hauv ntiaj teb thiab cov hlau hloov pauv. Ntxiv rau cov ntsev ntsev, muaj ammonium thiab hlau ntsev, magnesium, calcium, tooj liab, manganese, zinc, cobalt, txhuas thiab lwm yam ntsev uas muaj ntau yam siv.

Tsis tas li ntawd, EDTA kuj tuaj yeem siv los tshem tawm cov hlau tsis zoo, uas tau tshem tawm sai sai ntawm tib neeg lub cev.

FAQ:

1. Dab tsi yog qhov txawv ntawm sodium ntsev EDTA thiab EDTA?

В тех же щелочных условиях хелатирующая способность - EDTA (кислота)> ЭДТА 2NA>EDTA 4 NAS. Solubility ntawm acid EDTA thiab EDTA 2NA nyob rau hauv dej yog tsawg dua EDTA 4NA. Yog li, nyob ntawm pH ntawm qhov nruab nrab thiab solubility, cov khoom sib txawv EDTA yuav tsum tau ua.

2. Muaj pes tsawg tons ntawm lub thawv ntim khoom?

Rau EDTA 2Na 18/21 MT ntawm 20FCL. Rau EDTA 4Na 20/24 MT ntawm 20FCL. Rau acid EDTA 20/22 MT ntawm 20FCL.

3. Puas yog OEM pob khoom muaj?

Yog lawm, qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis rau OEM yog 20 lab tons. Peb tuaj yeem kho cov ntawv ntim khoom xa tuaj nrog rau lub hnab.

4. Koj puas muaj lub hnab loj?

Peb muaj 1 tuj hnab rau EDTA thiab 850 kg hnab rau 2Na EDTA.

5. Lub sijhawm khoom xa tuaj yog dab tsi?

1-5tons, lub sijhawm xa khoom 7 hnub ua haujlwm. Ntau tshaj 5 tons, lub sijhawm xa khoom yog 10-15 hnub ua haujlwm.

6. Hais txog qhov zoo.

Peb muab cov kev qhia tshwj xeeb ntawm kev lag luam, qib zaub mov zoo li qib tshuaj pleev ib ce. Yog tias muaj cov kev cai tshwj xeeb rau kev ntsuas thiab qhov zoo, thov qhia rau peb paub thiab peb yuav ua raws.

7. Yuav ua li cas txog lub peev xwm ntau lawm?

Lub peev xwm tsim tau ntawm EDTA sodium ntsev yog 26 000 tons hauv ib xyoos, thiab EDTA acids yog - 50 000 tons hauv ib xyoos.

8. Yuav ua li cas thiaj tau txais tus qauv?

Dawb 100g qauv nrog daim ntawv qhia. Thov hu rau koj tus thawj tswj kev muag khoom kom paub ntau ntxiv.
