I-Ethylenediaminetetraacetic acid (EDTA ACID)
IiNkcazo zeeMveliso
Njenge-agent enye ye-chelating, ingasetyenziselwa ukucocwa kwemizi-mveliso, ukusetyenziswa komntu kunye nekhaya, i-Bleaching of pulp kunye ne-textile, i-Micronutrients kwezolimo, i-Polymer processing kunye ne-Metal plating njl njl. Ngendlela yokongeza, iarhente esebenzayo, isicacisi, isisusa sesinyithi.Inkonzo yeeNkcukacha sinokubonelela ngazo:1. Isikhongozeli esixutyiweyo, sinokuxuba izinto ezahlukeneyo kwisikhongozeli esinye.2. Ulawulo lomgangatho, ngaphambi kokuthunyelwa, isampuli yasimahla yovavanyo. emva kokuthunyelwa, gcina isampuli iminyaka emi-33. Ukuthunyelwa ngokukhawuleza kunye namaxwebhu aqeqeshiweyo4. Ukupakisha njengesicelo sakho, kunye nefoto ngaphambi kokuthunyelwa. Izinto eziluncedo Zethu: Amava agcweleyo amanani amakhulu izikhongozeli ezilayishwa kwizibuko lolwandle lwaseTshayina ukuthunyelwa ngokukhawuleza ngokupakishwa kwelayini yokuthutha eyaziwayo ngepallet njengesicelo esikhethekileyo senkonzo yomthengi emva kokuthunyelwa ngemithwalo ye-imeyile kunye nenkonzo yokuthengiswa kweekhonteyina ezikhoyo ezivela kwimvelaphi yaseTshayina.
