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)
Nama CAS: 2809-21-4
Tātai rāpoi: C2H8O7P2
Whakamahi
Ko te HEDP he momo aukati waikura cathodic.Ina whakaritea ki te phosphates pararopi, ka taea te whakahuihui ki te konutai molybdate, te silicate, te tote konutea me te tahi-polymer te nuinga hei aukati waikura tauine i roto i te maimoatanga o te wai whakamahana hurihanga, te rama hinu mara me te wai kohua .Ka taea hoki te whakamahi hei sequestrant i roto i te hopi kaiwhakawhanake me te whiu whakarewa i roto i te whakakikorua hiko.
Te ahuatanga
Ka whakakorehia e te HEDP ki nga katote e rima he pai, he kino ranei, ka tarai i te katote whakarewa rua-valent i roto i te wai.No reira he pai te painga o te tauine.He tohu tenei hua ki te pāmahana teitei, te waikura me te uara pH teitei.E whakaatu ana i te tino whakahiato me te whakaoti i te paanga o te paepae i te wa e whakakotahihia ana me etahi atu aukati waikura me nga aukati tauine.
