HEDP Cas 2809-21-4 Etidronic Acid Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
Nambala ya CAS: 2809-21-4
Fomula ya Maselo: C2H8O7P2
Gwiritsani ntchito
HEDP ndi mtundu wa cathodic corrosion inhibitor. Poyerekeza ndi inorganic phosphates, imatha kuwonjezeredwa ndi sodium molybdate, silicate, zinc salt ndi co-polymer makamaka ngati scale corrosion inhibitor pochiza madzi ozizira, mafuta oundana ndi madzi a boiler. Itha kugwiritsidwanso ntchito ngati sequestrant mu detergent ndi complexing agent komanso metal scour mu electroplating.
Khalidwe
HEDP imatha kusuntha ma ioni asanu abwino kapena oipa ndikutulutsa ma ioni awiri achitsulo m'madzi. Chifukwa chake imakhala ndi mphamvu yabwino yoletsa kukula kwa scale. Izi zimateteza kutentha kwambiri, okosijeni komanso pH yokwera. Imakhala ndi mphamvu ya synergic komanso kuthetsa mavuto ngakhale ikuphatikizidwa ndi zoletsa zina za dzimbiri ndi zoletsa kukula kwa scale.
Kufotokozera
| Maonekedwe | Madzi owonekera bwino opanda utoto mpaka achikasu chopepuka |
| Zomwe zikugwira ntchito | ≥60.0% |
| Asidi ya phosphorous (monga PO33-) | ≤2.0% |
| Phosphoric acid (monga PO43-) | ≤0.8% |
| Chloride (monga Cl-) | ≤100ppm |
| Kuchulukana (20℃) | ≥1.40 g/cm3 |
| PH (1% yankho la madzi) | ≤2.0 |
| Kusunga calcium | ≥500 mgCaCO3/g |
Kagwiritsidwe Ntchito
HEDP ikhoza kuwonjezeredwa ndi hydroxylaectic acid, PAA, BTA, molybdate, copolymer, mchere wa zinc, kuti apange mankhwala a whole-organic-alkali kapena low-phosphor zinc-based agent of water treatment kuti agwiritsidwe ntchito m'njira zosiyanasiyana zoziziritsira madzi mosiyana ndi ubwino wa madzi. Mlingo nthawi zambiri umakhala 2 ~ 10mg/L pomwe HEDP imagwiritsidwa ntchito yokha.
Phukusi ndi Kusungirako
Dramu ya pulasitiki ya 250kg kapena 1250kg IBC, iyenera kusungidwa m'chipinda chozizira komanso chopanda mpweya wokwanira chaka chimodzi.
Chonde titumizireni uthenga kuti mupeze COA ndi MSDS. Zikomo.
