Features:
HEDP inonzi organophosphoric acid corrosion inhibitor. Inogona chelate neFe, Cu, uye Zn nezvimwe.
simbi ions uye inogadzira yakagadzikana yakaoma musanganiswa.
Inogona kunyungudutsa zvinhu zvine oxidized pane aya masimbi 'nzvimbo. Pasi pe250 ℃ HEDP inoratidza chiyero chepamusoro uye kugona kwekudzivirira.
HEDP ine kugadzikana kwakanaka kwemakemikari pasi pehupamhi hwepH, yakaoma kuita hydrolyzed, uye yakaoma kuodzwa pasi pechiedza chakajairwa uye mamiriro ekupisa. Asidhi yayo / alkali uye chlorine oxidation kushivirira zviri nani pane zveimwe organophosphoric acids (munyu).
HEDP inogona kuita nesimbi ions muhurongwa hwemvura kuita hexa-element chelating yakaoma, ine calcium ion kunyanya. Naizvozvo, HEDP ine yakanaka antiscale uye inooneka pachikumbaridzo mhedzisiro.
Kana ichivakwa pamwe chete nemamwe makemikari ekurapa mvura, inoratidza yakanaka synergistic mhedzisiro.
Iyo yakasimba yeHEDP yakakwira kuchena chigadzirwa, yakakodzera kushandiswa munguva yechando uye inotonhora matunhu.
yakanyatsokodzera kushandiswa semumiririri wekuchenesa muminda yemagetsi uye sekuwedzera mumakemikari ezuva nezuva.
Applications:
HEDP inoshandiswa zvakanyanya mukutenderedza mvura inotonhorera yemagetsi emagetsi, indasitiri yemakemikari, simbi, fetiraiza, nezvimwewo uye inoshandiswa zvakanyanya seyero uye corrosion inhibitor yepasi-pressure boilers, mvura yemumunda, pombi yemafuta.
Muchiedza & machira indasitiri, HEDP inoshandiswa sedetergent yesimbi uye isiri metal. Muindasitiri yekudhaya, HEDP inoshandiswa seperoxide stabilizer uye mugadziri wedhayi; Mune isiri-cyanide electroplating, HEDP inoshandiswa sechelating agent. Muyero we1-10mg/L inosarudzwa se scale inhibitor, 10-50mg/L se corrosion inhibitor, uye 1000-2000mg/L se detergent. Kazhinji, HEDP inoshandiswa pamwe chete nepolycarboxylic acid.
