HEDP inodzivirira ngura ye organophosphorus acid. Inogona kucheneruka nemaion eFe, Cu, uye Zn kuti igadzire macompounds echelating akagadzikana. Inogona kunyungudutsa zvinhu zvakasanganiswa ne oxidized pamusoro pesimbi idzi. HEDP inoratidza mhedzisiro yakanaka kwazvo yekudzikamisa kukura uye ngura pasi pekupisa kwe250℃. HEDP ine kugadzikana kwakanaka kwemakemikari kana iine pH yakakwira, yakaoma hydrolyzed, uye yakaoma kuora kana iine chiedza chakajairika uye mamiriro ekupisa. Kushivirira kwayo acid/alkali uye chlorine oxidation kuri nani pane kwemamwe organophosphorus acids (munyu). HEDP inogona kuita nemaion esimbi mumvura kuti igadzire hexa-element chelating complex, kunyanya necalcium ion. Nokudaro, HEDP ine mhedzisiro yakanaka yekusakura uye inooneka. Kana yakavakwa pamwe chete nemamwe makemikari ekurapa mvura, inoratidza mhedzisiro yakanaka yekubatana. Mamiriro akasimba e HEDP ipfu yekristaro, yakakodzera kushandiswa munguva yechando nenzvimbo dzinotonhora zvikuru. Nekuda kwekuchena kwayo kwakanyanya, inogona kushandiswa semushonga wekuchenesa munzvimbo dzemagetsi uye sezvinhu zvinowedzerwa mumakemikari ezuva nezuva.
HEDP inoshandiswa senzira yekudzikamisa ngura uye kudzikamisa ngura mumidziyo yemvura inotonhorera inotenderera, nzvimbo yemafuta uye mabhoyira ane simba shoma muminda yakaita semagetsi, indasitiri yemakemikari, simbi, fetereza, nezvimwewo. Muindasitiri yakarukwa zvishoma, HEDP inoshandiswa semushonga wekushambidza simbi neisiri simbi. Muindasitiri yekudhaya, HEDP inoshandiswa se peroxide stabilizer uye dye-fixing agent; Mu electroplating isiri cyanide, HEDP inoshandiswa semushonga wekubvisa tsvina. Chipimo che1-10mg/L chinosarudzwa semushonga wekucheka, 10-50mg/L semushonga wekubvisa ngura, uye 1000-2000mg/L semushonga wekuchenesa. Kazhinji, HEDP Inoshandiswa pamwe chete ne polycarboxylic acid.
