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)
Nhamba yeCAS: 2809-21-4
Molecular Formula: C2H8O7P2
Shandisa
HEDP imhando ye cathodic corrosion inhibitor.Kana ichienzaniswa neinorganic phosphates, inogona kusanganiswa ne sodium molybdate, silicate, zinc munyu uye co-polymer kunyanya sescale corrosion inhibitor mukurapa kwe cyclic kutonhora mvura, oiri field flash uye boiler mvura .Inogona zvakare kushandiswa sesequestrant mune detergent uye complexing agent uye metal scour mu electroplating.
Hunhu
HEDP inogona kubatanidza maion mashanu akanaka kana kuti asina kunaka uye chelate iyoni-valent metal ion mumvura.Saka zvinotora chiyero chakanaka chekudzivisa.Ichi chigadzirwa chiratidzo chinopesana nekushisa kwakanyanya, oxidizing uye yakakwirira pH kukosha.Iyo inoratidza yakakwana synergic mhedzisiro uye kugadzirisa chikumbaridzo mhedzisiro uku ichisanganiswa nemamwe corrosion inhibitors uye scale inhibitors.
