Matumizi:
HEDP hutumika kama kizuizi cha kiwango na kutu katika kuzunguka kwa mfumo wa maji baridi, uwanja wa mafuta na boilers zenye shinikizo la chini katika nyanja kama vile nguvu za umeme, tasnia ya kemikali, madini, mbolea, nk. Katika tasnia nyepesi iliyosokotwa, HEDP hutumika kama sabuni ya chuma na isiyo ya chuma. Katika tasnia ya kupaka rangi, HEDP hutumika kama kiimarishaji cha peroksidi na wakala wa kurekebisha rangi; Katika electroplating isiyo ya sianidi, HEDP hutumika kama wakala wa chelating. Kipimo cha 1-10mg/L kinapendekezwa kama kizuia mizani, 10-50mg/L kama kizuizi cha kutu, na 1000-2000mg/L kama sabuni. Kwa kawaida, HEDP Inatumika pamoja na asidi ya polycarboxylic.
Kifurushi na Hifadhi:
HEDP kioevu: 200L ngoma ya plastiki, IBC (1000L), mahitaji ya wateja.
HEDP imara: 25kg / mfuko, mahitaji ya wateja.
Hifadhi kwa miezi kumi na mbili katika chumba chenye kivuli na mahali pakavu.
