I-HEDP CAS 2809-21-4 Etidronic acid monohydrate
I-1-hydroxyethyylidene-1,1-diphohosphonic acid / HEDP CAS 2809-21-4
I-1-hydroxyethyylidene-1,1-diphophonic acid (HEDP)
I-COS NO: 2809-21-4-4
Ifomula ye-molecular: c2h8o7p2
Sebenzisa
I-HEDP uhlobo lwe-cathodic corrosion inhibitor. Uma kuqhathaniswa nama-phosphates ama-inorganic, kungahlanganiswa nge-sodium molybdate, izimbumbulu, usawoti kasawoti kanye ne-co-polymer ikakhulukazi njengoba amanzi e-corlosion kanye namanzi we-boiler .Kwase futhi asetshenziswe njenge-sequestrant ku-detergent futhi I-Agent enobunzima nensimbi yensimbi ku-electroplating.
-Yisimilo
I-HEDP ingahle ikhiphe ama-ion amahlanu amahle noma alungile futhi abheke i-ion yensimbi emibili emanzini. Ngakho-ke kuthatha umphumela omuhle wokuvimbela umphumela. Lo mkhiqizo ungubufakazi obuphikisana nokushisa okuphezulu, i-oxidizing kanye nenani eliphakeme le-PH. Kubonisa umphumela ophelele we-Synergic kanye nokuxazulula umphumela womkhawulo ngenkathi kuhlanganiswa nezinye izinhlanga ezivinjelwe kanye nama-scale shihibitors.

Umsebenzi
I-HEDP ingahlanganiswa nge-hydroxylaetic acid, i-PAA, BTA, Molybdate, Copolymer, i-zinc usawoti, ukwenza i-ejenti ye-organic-alkali ye-organic noma i-agent ephansi ye-organic ye-organic kusuka kwikhwalithi yamanzi. I-Dose ngokuvamile ingu-2 ~ 10mg / l ngenkathi i-hedp isetshenziswa yedwa.
Iphakheji kanye nesitoreji
I-250kg yepulasitiki yepulasitiki noma i-1250kg IBC, izogcinwa egumbini elipholile futhi elinomoya onomoya onomoya onomoya wonyaka owodwa.
Pls Xhumana nathi ukuthola i-COA ne-MSDS. Ngiyabonga.
