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
Chilinganizo cha Molecular: C2H8O7P2
Gwiritsani ntchito
HEDP ndi mtundu wa cathodic corrosion inhibitor. Poyerekeza ndi mankwala phosphates, zikhoza kuphatikizidwa ndi sodium molybdate, silicate, mchere nthaka ndi co-polymer makamaka monga sikelo dzimbiri inhibitor pochiza cyclic kuzirala madzi, mafuta kung'anima kumunda ndi kukatentha madzi .It Angagwiritsidwenso ntchito ngati sequestrant mu detergent ndi complexing wothandizila ndi zitsulo scour electroplating.
Khalidwe
HEDP imatha kulumikiza ma ion asanu kukhala abwino kapena ayi ndikuthira ayoni wazitsulo ziwiri m'madzi. Chifukwa chake zimatengera sikelo yabwino yolepheretsa. Izi ndi umboni motsutsana ndi kutentha kwakukulu, oxidizing ndi pH mtengo wapamwamba. Imawonetsa zotsatira zabwino za synergic ndikuthana ndi vuto pomwe zikuphatikizidwa ndi ma corrosion inhibitors ndi ma scale inhibitors.

Kugwiritsa ntchito
HEDP ikhoza kuphatikizidwa ndi hydroxylaectic acid, PAA, BTA, molybdate, copolymer, zinki mchere, kupanga zonse-organic-alkali kapena otsika phosphor zinki-based wothandizira madzi kuti agwiritsidwe ntchito mumitundu yonse yamadzi ozizira ozungulira osiyanasiyana ndi madzi. Mlingo nthawi zambiri ndi 2 ~ 10mg/L pomwe HEDP imagwiritsidwa ntchito yokha.
Phukusi ndi Kusunga
250kg pulasitiki ng'oma kapena 1250kg IBC, kusungidwa m'chipinda ozizira ndi mpweya wokwanira ndi alumali nthawi ya chaka chimodzi.
Pls tilankhule nafe kuti tipeze COA ndi MSDS. Zikomo.
