HEDPhe mea ʻoki kūpikipiki waikawa organophosphoric. Hiki iā ia ke chelate me nā Fe, Cu, a me Zn ions e hana i nā mea chelating stable.HEDP hōʻike i nā pālākiō maikaʻi loa a me nā hopena kaohi kūpē ma lalo o ka mahana 250 ℃. HEDPhe kūpaʻa kemika maikaʻi ma lalo o ke kumu kiʻekiʻe o ka pH, paʻakikī e hydrolyzed, a paʻakikī e decomposed ma lalo o ke ʻano maʻamau a me nā ʻano wela. ʻOi aku ka maikaʻi o ka ʻakika / alkali a me ka chlorine oxidation tolerance ma mua o kēlā me nā acid acid (ph paʻakai) ʻē aʻe.HEDPhiki ke hana me nā iona metala i loko o ka ʻōnaehana wai e hana i ka paʻakikī hexa-element chelating complex, me ka ion ion i loko. No laila,HEDPloaʻa nā hopena antiscale maikaʻi a ʻike ʻia hoʻi. Ke kūkulu pū ʻia me nā kemika lapaʻau wai ʻē aʻe, hōʻike ia i nā hopena synergistic maikaʻi. Ke kūlana paʻa oHEDPʻo ia ka pauma aniani, kūpono no ka hoʻohana ʻana i nā ʻāina hoʻoilo a me nā moku hau. Ma muli o kona maʻemaʻe kiʻekiʻe, hiki ke hoʻohana ʻia i mea hoʻomaʻemaʻe ma nā kahua uila a me nā mea hoʻohui i nā kemika o kēlā me kēia lā.
