Katundu: Ethylene Diamine Tetraacetic Acid Tetrasodium (EDTA Na4)
CAS#: 64-02-8
Fomula: C10H12N2O8Na4·4H2O
Kapangidwe ka Chilinganizo:
Ntchito: Amagwiritsidwa ntchito ngati zinthu zofewetsa madzi, zinthu zoyambitsa mphira wopangidwa, zinthu zosindikizira ndi kupaka utoto, komanso zinthu zotsukira madzi.
Mafotokozedwe:

Njira yogulitsira:
Imapezeka kuchokera ku zomwe ethylenediamine imachita ndi chloroacetic acid, kapena kuchokera ku zomwe ethylenediamine imachita ndi formaldehyde ndi sodium cyanide.
Mawonekedwe:
EDTA 4NA ndi ufa woyera wa kristalo womwe uli ndi madzi anayi a kristalo, umasungunuka mosavuta m'madzi, madzi amchere ndi amchere, umasungunuka pang'ono mu zosungunulira zachilengedwe monga ethanol, ukhoza kutaya madzi enaake kapena onse a kristalo pa kutentha kwakukulu.
Mapulogalamu:
EDTA 4NA ndi chida choyezera ma ion achitsulo chomwe chimagwiritsidwa ntchito kwambiri.
1. Itha kugwiritsidwa ntchito mumakampani opanga nsalu popaka utoto, kuwonjezera mitundu, kukonza mtundu ndi kuwala kwa nsalu zopaka utoto.
2. Amagwiritsidwa ntchito ngati chowonjezera, choyambitsa, chophimba ma ion achitsulo komanso choyambitsa mumakampani opanga mphira wa butadiene.
3. Itha kugwiritsidwa ntchito m'makampani ouma a acrylic kuti athetse kusokonezeka kwa zitsulo.
4. EDTA 4NA ingagwiritsidwenso ntchito mu sopo wamadzimadzi kuti iwonjezere ubwino wa kutsuka ndi kutsuka.
5. Amagwiritsidwa ntchito ngati chofewetsa madzi, chotsukira madzi, komanso chotsukira madzi.
6. Amagwiritsidwa ntchito ngati chothandizira cha mphira chopangidwa, chomaliza cha polymerization ya acrylic, othandizira osindikizira ndi kupaka utoto, ndi zina zotero.
7. Imagwiritsidwanso ntchito poyesa titration mu kusanthula mankhwala, ndipo imatha kusanthula molondola ma ayoni osiyanasiyana achitsulo.
8. Kuwonjezera pa ntchito zomwe zili pamwambapa, EDTA 4NA ingagwiritsidwenso ntchito m'mafakitale opanga mankhwala, mankhwala a tsiku ndi tsiku, kupanga mapepala ndi mafakitale ena.
