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 ma phosphates achilengedwe, amatha kuphatikizidwa ndi sodium molybdate, silicate, mchere wa zinc ndi co-polymer makamaka ngati inhibitor yayikulu pochiza madzi ozizira a cyclic, kung'anima kwamafuta ndi madzi otentha. complexing agent ndi chitsulo scour mu 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.
Kufotokozera

Kugwiritsa ntchito
HEDP ikhoza kuphatikizidwa ndi hydroxylaectic acid, PAA, BTA, molybdate, copolymer, zinki mchere, kupanga zonse-organic-alkali kapena otsika phosphor nthaka ofotokoza wothandizira madzi kuti agwiritsidwe ntchito mumitundu yonse yamadzi ozizira ozungulira osiyanasiyana. kuchokera ku khalidwe la madzi.Mlingo nthawi zambiri ndi 2 ~ 10mg/L pamene 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.
