Zvimiro:
HEDP inodzivirira corrosion ye organophosphorus acid. Inogona kupararira neFe, Cu, uye Zn nezvimwewo.
maayoni esimbi uye anoumba musanganiswa wakasimba wakaomarara.
Inogona kunyungudutsa zvinhu zvakasanganiswa ne oxidized pamusoro pesimbi idzi. Pasi pe 250℃ HEDP inoratidza kugona kukuru kwehukuru uye kudzivirira ngura.
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 ari mumvura kuti igadzire hexa-element chelating complex, kunyanya calcium ion. Nokudaro, HEDP ine mhedzisiro yakanaka yekusakura uye inoonekwa.
Kana yakavakwa pamwe chete nemamwe makemikari ekurapa mvura, inoratidza mhedzisiro yakanaka yekubatana.
Chinhu chakasimba cheHEDP chakachena kwazvo, chakakodzera kushandiswa munguva yechando nenzvimbo dzinotonhora.
yakakodzera kushandiswa semushonga wekuchenesa muminda yemagetsi uye sezvinhu zvinowedzerwa mumakemikari ezuva nezuva.
Mashandisirwo:
HEDP inoshandiswa zvakanyanya mumagetsi, makemikari, simbi, fetereza, nezvimwewo, uye inoshandiswa zvakanyanya senzira yekudzora ngura yemaboiler ane simba shoma, mafashamo emvura mumunda, mapaipi emafuta.
Muindasitiri yechiedza nemachira, HEDP inoshandiswa sechinosuka chesimbi neisiri simbi. Muindasitiri yekudhaya, HEDP inoshandiswa sechinosimbisa peroxide uye chinogadzirisa dhayi; Muindasitiri yemagetsi isiri cyanide, HEDP inoshandiswa sechinosuka chelating. Chiyero che1-10mg/L chinosarudzwa sechinodzika scale inhibitor, 10-50mg/L sechinodzika ngura, uye 1000-2000mg/L sechinosuka. Kazhinji, HEDP inoshandiswa pamwe chete nepolycarboxylic acid.
