Habka wax soo saarka:
Waxaa laga helaa falcelinta ethylenediamine oo leh chloroacetic acid, ama falcelinta ethylenediamine oo leh formaldehyde iyo sodium cyanide.
Astaamaha:
EDTA 4NA waa budo cad oo crystalline ah oo ka kooban 4 biyo crystal ah, si fudud ugu milmi kara biyaha, xalka biyaha waa alkaline, wuxuu si yar ugu milmi karaa dareerayaasha dabiiciga ah sida ethanol, wuxuu waayi karaa qayb ama dhammaan biyaha crystal heerkulka sare.
Codsiyada:
EDTA 4NA waa kiimiko bir ah oo si weyn loo isticmaalo.
1. Waxaa loo isticmaali karaa warshadaha dharka si loo midabeeyo, loo hagaajiyo midabka, loo hagaajiyo midabka iyo dhalaalka dharka la midabeeyay.
2. Waxaa loo isticmaalaa sidii wax lagu daro, firfircooni, wakiilka maaskaro ee birta iyo firfircooni warshadaha caagga ah ee butadiene.
3. Waxaa loo isticmaali karaa warshadaha akrilik qalalan si loo yareeyo faragelinta birta.
4. EDTA 4NA waxaa sidoo kale loo isticmaali karaa saabuunta dareeraha ah si loo hagaajiyo tayada dhaqidda iyo saameynta dhaqidda.
5. Waxaa loo isticmaalaa jilciyaha biyaha, nadiifiyaha biyaha, oo loo isticmaalo daawaynta tayada biyaha.
6. Waxaa loo isticmaalaa sida kataliye caag ah oo macmal ah, joojiye polymerization acrylic, daabacaad iyo kaaliyeyaal rinjiyeyn, iwm.
7. Waxa kale oo loo isticmaalaa titration-ka falanqaynta kiimikada, waxayna si sax ah u titrin kartaa noocyo kala duwan oo ah ayoonnada birta ah.
8. Marka laga soo tago isticmaalka kor ku xusan, EDTA 4NA waxaa sidoo kale loo isticmaali karaa dawooyinka, kiimikada maalinlaha ah, sameynta waraaqaha iyo warshadaha kale.
