Usetyenziso:
I-1.HEDP isetyenziselwa isikali kunye nokuthintela ukubola ekujikelezeni inkqubo yamanzi epholileyo, intsimi yeoli kunye ne-boilers yoxinzelelo oluphantsi kwiindawo ezifana namandla ombane, imboni yeekhemikhali, i-metallurgy, isichumisi, njl.
2.Kushishino olulukiweyo olulula, i-HEDP isetyenziswa njengesicoci sesinyithi kunye nesingeyontsimbi. Kwishishini lokudaya, i-HEDP isetyenziswa njenge-peroxide stabilizer kunye ne-agent yokulungisa idayi;
3.Kwi-non-cyanide electroplating, i-HEDP isetyenziswa njenge-agent chelating. I-dosage ye-1-10mg / L ikhethwa njenge-inhibitor yesikali, i-10-50mg / L njenge-corrosion inhibitor, kunye ne-1000-2000mg / L njenge-detergent.
4.Ngokuqhelekileyo, i-HEDP isetyenziswa kunye ne-polycarboxylic acid.
