1-Hydroxy Ethylidene-1,1-Diphosphonic Acid
(HEDP)
CAS No. 2809-21-4
Molecular Formula: C 2 H 8O 7P 2
Molecular yuag: 206,02
Properties:
HEDP yog ib qho organophosphoric acid xeb inhibitor. Nws yuav chelate nrog Fe, Cu, thiab ZN ions tsim ruaj khov chelating compounds.It yuav yaj oxidized ntaub ntawv nyob rau hauv cov hlau 'chaw. HEDP qhia tau hais tias zoo heev scale thiab corrosion inhibition los nyob rau hauv kub 250 ° C. HEDP muaj zoo tshuaj stability nyob rau hauv siab pH nqi, ib qho nyuaj rau yuav hydrolyzed, thiab nyuaj rau yuav decomposed nyob rau hauv zoo tib yam lub teeb thiab kub tej yam kev mob. Nws acid / alkali thiab tshuaj oxidation kam yog zoo dua li ntawd ntawm lwm yam organophosphoric acids (ntsev). HEDP yuav hnov mob nrog hlau ions nyob rau hauv dej system tsim Hexa-caij chelating complex, uas muaj calcium ion nyob rau hauv particular. Yog li ntawd,HEDP muaj zoo antiscale thiab pom pib los. Thaum ua ke nrog rau lwm cov dej kev kho mob tshuaj, nws qhia tau hais tias zoo synergistic los.
Cov khoom hauv lub xeev ntawm HEDP yog siv lead ua hmoov, haum rau pab nyob rau hauv lub caij ntuj no thiab khov cheeb tsam. Vim hais tias ntawm nws cov high purity, nws yuav siv tau raws li tu neeg sawv cev nyob rau hauv hluav taws xob teb thiab raws li additives nyob rau hauv txhua txhua hnub tshuaj.

pab
HEDP yog siv raws li teev thiab corrosion inhibition nyob rau hauv circulating dej txias system, roj teb thiab tsawg-siab boilers nyob rau hauv teb xws li hluav taws xob lub hwj chim, tshuaj kev lag luam, metallurgy, chiv, thiab lwm yam .. Nyob rau hauv lub teeb woven kev lag luam,HEDP yog siv raws li xab npum rau hlau thiab nonmetal. Nyob rau hauv dyeing kev lag luam,HEDP yog siv raws li peroxide stabilizer thiab zas-kho neeg sawv cev; Nyob rau hauv uas tsis yog-cyanide electroplating,HEDP yog siv raws li chelating neeg sawv cev. Cov tshuaj ntawm 1-10mg / L yog dua li teev inhibitor, 10-50mg / L raws li xeb inhibitor, thiab 1000-2000mg / L raws li xab npum. Feem ntau,HEDP yog siv ua ke nrog polycarboxylic acid.
